Background

In a conventional Thin film transistor liquid crystal display (TFT-LCD) product, when a digital signal is transmitted in a digital channel, the digital signal is transmitted from a control (TCON) end to a drive (Driver) end, and the transmitted digital signal needs to be encoded and then transmitted in a baseband. Since there is no independent clock signal in the data transmission process, the clock signal is embedded into the data. When a plurality of consecutive 0 s or consecutive 1 s occur in the transmission data, the receiving end easily recognizes the embedded clock signal by mistake. The purpose of encoding is to make the transmission signal be a square wave with a certain jump, so as to prevent the clock synchronization information received by the receiving end from being easy to generate errors and finally causing error codes due to the excessive number of continuous 0 or continuous 1.

Currently, the most widely used encoding scheme in the field of data transmission is to encode all data packets (packets) (i.e., raw data), so that a lot of time is consumed for data encoding and decoding during the data transmission process, thereby causing problems of slow data transmission, influence on response time and image quality, and the like.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Fig. 1 is a flowchart illustrating steps of a data encoding method according to an embodiment of the present invention. The method comprises the following steps:

step S110: raw data is acquired.

Specifically, the original data includes a plurality of data streams. The data streams are arranged in sequence, and the data streams are coded in sequence in the coding process. When data is transmitted, the data streams are transmitted in sequence according to the coding sequence of the data streams.

Step S120: and acquiring a first data stream which does not meet the preset standard and recording the first data stream as a data stream to be assigned.

Wherein the data stream comprises a first predetermined number of data bits, each of the data bits being filled with a respective value, the predetermined criterion being that the same value in consecutive data bits does not exceed a second predetermined number. In this embodiment, the value of the first predetermined number is greater than the value of the second predetermined number, and the first predetermined number is 8, so that the first data stream is 8-Bit data. Each of said data bits is filled with a respective value, e.g. the first data stream, recorded as a square wave signal, has a data bit filling with a respective value of either 0 or 1.

The operation method of the predetermined criteria will be described in detail below. Assuming that the first data stream is 8-Bit data (i.e., M0-M7 data bits), and the second predetermined number is 5, the detailed logic operation of the predetermined criteria is as follows: NAND (M7-M2), NAND (M6-M1), NAND (M5-M0), OR (M7-M2), OR (M6-M1), OR (M5-M0)) ═ 1. Where (M7-M2) denotes M7, M6, M5, M4, M3 and M2, and the others refer to (M7-M2), NAND denotes an exclusive-OR operation, OR denotes an OR operation, and ═ denotes whether OR not equal to. Thus, NAND (M7-M2), NAND (M6-M1), NAND (M5-M0) indicates whether OR not 0 exists in every 6 consecutive values of M7-M0, OR (M7-M2), OR (M6-M1), OR (M5-M0) indicates whether OR not 1 exists in every 6 consecutive values of M7-M0. That is, there are consecutive same values in the first data stream, for example, in an 8-Bit first data stream (10111111), the first data stream is the first data stream that does not satisfy the predetermined standard, and the first data stream may be a data signal with error in the channel transmission process.

Step S130: and performing logic operation on each data bit in the data stream to be assigned and assigning the data bit to each data bit in a second data stream.

In this embodiment, the number of data bits in the second data stream is greater than the number of data bits in the first data stream. The number of data bits of the second data stream is 9.

The method has the advantages that the first data stream which does not meet the preset standard is obtained and recorded as the data stream to be assigned, the first data stream in the data stream to be assigned is operated to generate the second data stream which meets the preset standard, and the data stream which meets the preset standard is added with a third preset number of data bits to obtain the second data stream. Therefore, the data stream meeting the preset standard can be screened out, and only the data stream not meeting the preset standard is coded, so that the complexity of data calculation is reduced, and the transmission efficiency of data is improved.

Fig. 2 is a flowchart illustrating steps of a data encoding method according to a second embodiment of the present invention. The method comprises the following steps:

step S210: raw data is acquired.

Specifically, the original data includes a plurality of data streams. The data streams are arranged in sequence, and the data streams are coded in sequence in the coding process. When data is transmitted, the data streams are transmitted in sequence according to the coding sequence of the data streams.

Step S220: and judging whether each first data stream meets a preset standard or not.

Wherein the data stream comprises a first predetermined number of data bits, each of the first data bits being filled with a respective value, the predetermined criterion being that the same value in consecutive data bits does not exceed a second predetermined number. In this embodiment, the value of the first predetermined number is greater than the value of the second predetermined number, and the first predetermined number is 8, so that the first data stream is 8-Bit data. Each of said data bits is filled with a respective value, e.g. the first data stream, recorded as a square wave signal, has a data bit filling with a respective value of either 0 or 1.

The operation method of the predetermined criteria will be described in detail below. Assuming that the first data stream is 8-Bit data (i.e., M0-M7 data bits), and the second predetermined number is 5, the detailed logic operation of the predetermined criteria is as follows: NAND (M7-M2), NAND (M6-M1), NAND (M5-M0), OR (M7-M2), OR (M6-M1), OR (M5-M0)) ═ 1. Where (M7-M2) denotes M7, M6, M5, M4, M3 and M2, and the others refer to (M7-M2), NAND denotes an exclusive-OR operation, OR denotes an OR operation, and ═ denotes whether OR not equal to. Thus, NAND (M7-M2), NAND (M6-M1), NAND (M5-M0) indicates whether OR not 0 exists in every 6 consecutive values of M7-M0, OR (M7-M2), OR (M6-M1), OR (M5-M0) indicates whether OR not 1 exists in every 6 consecutive values of M7-M0.

Step S230: and acquiring a first data stream which does not meet the preset standard and recording the first data stream as a data stream to be assigned.

I.e. there are consecutive identical values in the data stream, e.g. (10111111) in an 8-Bit first data stream, which is a data stream that does not meet the predetermined criteria, which may be a data signal with errors during the channel transmission.

Step S240: and performing logic operation on each data bit in the data stream to be assigned and assigning the data bit to each data bit in a second data stream.

In this embodiment, the number of data bits in the second data stream is greater than the number of data bits in the first data stream. The number of data bits of the second data stream is 9. When carrying out logic assignment on a data stream to be assigned, firstly, a tag value of the data stream to be assigned is acquired, where the tag value is used to improve the discreteness of the data stream, and the specific steps are as follows:

referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps of step S240 in fig. 2.

step S241: the value of the third data bit in the first data stream is assigned to the zeroth data bit in the second data stream.

Step S242: the value of the fifth data bit in the first data stream is assigned to the third data bit in the second data stream.

Step S243: the value of the sixth data bit in the first data stream is assigned to the fourth data bit in the second data stream.

Step S244: the value of the fourth data bit in the first data stream is assigned to the seventh data bit in the second data stream.

Step S245: the value of the seventh data bit in the first data stream is assigned to the eighth data bit in the second data stream.

When any one of the following conditions is met in the second data stream, the first data bit in the second data stream is a second value, and when the second data bit in the first data stream is a first value and the first data bit in the first data stream is a second value, the first data bit in the second data stream is a second value; the second case is when the third data bit in the first data stream is the first value, the second data bit in the first data stream is the second value and the first data bit in the first data stream is the second value, the first data bit in the second data stream is the second value; the third case is when the second data bit in the first data stream is the first value and the zeroth data bit in the first data stream is the first value, the first data bit in the second data stream is the second value.

When any one of the following conditions is met in the second data stream, the second data bit in the second data stream is a second value, and when the second data bit in the first data stream is the second value and the first data bit in the first data stream is the first value, the second data bit in the second data stream is the second value; the second case is when the third data bit in the first data stream is the first value, the second data bit in the first data stream is the second value and the first data bit in the first data stream is the second value, the second data bit in the second data stream is the second value; the third case is when the first data bit in the first data stream is the first value and the zeroth data bit in the first data stream is the second value, the second data bit in the second data stream is the second value.

When any one of the following conditions is met in the second data stream, the second data bit in the fifth data stream is a second value, and when the fourth data bit in the first data stream is a first value, the second data bit in the first data stream is a first value, and the first data bit in the first data stream is a first value, the second data bit in the fifth data stream is a second value; the second case is that when the second data bit in the first data stream is the second value and the zeroth data bit in the first data stream is the first value, the second data bit in the fifth data stream is the second value; the third case is when the first data bit in the first data stream is the second value and the zeroth data bit in the first data stream is the first value, the second data bit in the fifth data stream is the second value.

When any one of the following conditions is met in the second data stream, the second data bit in the sixth data stream is the second value, and when the fourth data bit in the first data stream is the first value, the second data bit in the first data stream is the first value, and the first data bit in the first data stream is the first value, the second data bit in the sixth data stream is the second value; the second case is that when the second data bit in the first data stream is the second value and the zeroth data bit in the first data stream is the second value, the second data bit in the sixth data stream is the second value; the third case is when the first data bit in the first data stream is the second value and the zeroth data bit in the first data stream is the second value, the second data bit in the sixth data stream is the second value.

Wherein the first value is 0 and the second value is 1.

The operation is obtained by performing a plurality of test tests, and the discreteness of the first data stream can be effectively adjusted. In some other embodiments, the operation may also be performed by a logical operation, such as

And acquiring values of a plurality of data bits in the data stream to be assigned with the values.

In this embodiment, for example, when the data stream of 8 bits is (10111111), M0 and M1 are selected, i.e., M0 is equal to 1 and M1 is equal to 0. The number of the selected data bits is not limited, and two data bits are generally selected for calculation. The selected data bit may be any, and in general, adjacent data bits are selected to improve the discreteness of the data stream (i.e., to increase the waveform hopping frequency of data).

And carrying out XOR operation on the numerical values of a plurality of data bits in the data stream to be assigned to obtain the tag value of the data stream to be assigned.

For example, M0 ═ 1 and M1 ═ 0 are selected. Let the flag value be X, X ═ NAND (M0, M1).

And performing logic operation on each data bit in the data stream to be assigned according to the tag value and assigning to each data bit in a second data stream.

According to the calculation in steps S241 and S242, X is 0, and the logical operation in this embodiment is as follows, since the second data stream is 9 bits (i.e. there are 9 data bits) N0-N8, where N0 is equal to M1, N1 is equal to M1, N2 is equal to M1, N3 is equal to M2, N4 is equal to NAND (X, M3), N5 is equal to NAND (X, M4), N6 is equal to M5, N7 is equal to NAND (X, M6), and N8 is equal to NAND (X, M7). The discreteness of the data stream can be increased by the logic operation.

Step S231: and acquiring a first data stream meeting a preset standard and recording the first data stream as a data stream to be filled.

In this step, please refer to the calculation method in step S120 for the detailed calculation method of the preset standard, which is not described herein again.

Step S232: and adding a third preset number of data bits to the data stream to be filled to obtain the second data stream.

In this embodiment, the third predetermined number is 1, but is not limited thereto, and the encoding of the signal may be more bits, for example, 8 bits may be converted into 10 bits, etc., according to the requirement of the product. In this step, only the third preset number of data bits is added to the data stream to be padded, and the calculation amount of performing logic operation on each data bit in the data stream to be assigned and assigning the data bit to each data bit in the second data stream is small compared with that of performing logic operation on each data bit in the data stream to be assigned, so that the operation time of encoding and decoding can be simplified, and the transmission efficiency of data is improved.

In addition, in this embodiment, the third predetermined number is 1, that is, the transmission channel is saved by converting 8 bits into 9 bits compared with converting 8 bits into 10 bits.

The method has the advantages that the first data stream which does not meet the preset standard is obtained and recorded as the data stream to be assigned, the first data stream in the data stream to be assigned is operated to generate the second data stream which meets the preset standard, and the data stream which meets the preset standard is added with a third preset number of data bits to obtain the second data stream. Therefore, the data stream meeting the preset standard can be screened out, and only the data stream not meeting the preset standard is coded, so that the complexity of data calculation is reduced, and the transmission efficiency of data is improved.

Fig. 4 is a schematic structural diagram of a data encoding device according to a third embodiment of the present invention. The device includes: the data acquisition unit 10, the assigned value data acquisition unit 20, and the data assignment unit 30.

The data acquisition unit 10 is used to acquire the original data stream. Specifically, the original data includes a plurality of data streams. The data streams are arranged in sequence, and the data streams are coded in sequence in the coding process. When data is transmitted, the data streams are transmitted in sequence according to the coding sequence of the data streams.

The assigned data acquiring unit 20 is configured to determine whether the discreteness of each of the first data streams meets a preset criterion. Wherein the first data stream comprises a first predetermined number of data bits, each of the data bits being filled with a corresponding value, the predetermined criterion being that the same value in consecutive data bits does not exceed a second predetermined number. In this embodiment, the value of the first predetermined number is greater than the value of the second predetermined number, and the first predetermined number is 8, so that the first data stream is 8-Bit data. Each of said data bits is filled with a respective value, e.g. the first data stream, recorded as a square wave signal, has a data bit filling with a respective value of either 0 or 1.

The operation method of the predetermined criteria will be described in detail below. Assuming that the data stream is 8-Bit data (i.e., M0-M7 data bits), and the second predetermined number is 5, the detailed logic operation of the predetermined criteria is as follows: NAND (M7-M2), NAND (M6-M1), NAND (M5-M0), OR (M7-M2), OR (M6-M1), OR (M5-M0)) ═ 1. Where (M7-M2) denotes M7, M6, M5, M4, M3 and M2, and the others refer to (M7-M2), NAND denotes an exclusive-OR operation, OR denotes an OR operation, and ═ denotes whether OR not equal to. Thus, NAND (M7-M2), NAND (M6-M1), NAND (M5-M0) indicates whether OR not 0 exists in every 6 consecutive values of M7-M0, OR (M7-M2), OR (M6-M1), OR (M5-M0) indicates whether OR not 1 exists in every 6 consecutive values of M7-M0.

The same values are continuously present in the first data stream, for example, in a 8-Bit first data stream (10111111), the first data stream is a data stream that does not meet the predetermined standard, and the first data stream may generate error data signals during channel transmission.

The data assigning unit 30 is configured to perform a logic operation on each data bit in the data stream to be assigned and assign the data bit to each data bit in the second data stream. In this embodiment, the number of data bits in the second data stream is greater than the number of data bits in the data stream. The number of data bits of the second data stream is 9.

The method has the advantages that the first data stream which does not meet the preset standard is obtained and recorded as the data stream to be assigned, the first data stream in the data stream to be assigned is operated to generate the second data stream which meets the preset standard, and the data stream which meets the preset standard is added with a third preset number of data bits to obtain the second data stream. Therefore, the data stream meeting the preset standard can be screened out, and only the data stream not meeting the preset standard is coded, so that the complexity of data calculation is reduced, and the transmission efficiency of data is improved.
