Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure.

Example one

Fig. 1 is a schematic view of a stereoscopic display device of a light splitting device according to an embodiment of the present invention.

The stereoscopic display equipment with the light splitting device comprises a display panel 110 and the light splitting device 120, wherein the distance between the display panel and the light splitting device is smaller than the focal length f of the light splitting device, and the distance d from the focal point of the light splitting device to the display panel is configured to be 0.4f-0.6f, so that the brightness change of the stereoscopic display equipment when the stereoscopic display equipment is watched at different angles is within a preset range.

At present, in the technology of implementing stereoscopic display based on a light splitting device and a display panel, the implementation of a naked-eye 3D mobile phone generally implements stereoscopic display by covering the light splitting device on a pixel display panel, where the light splitting device may generally be a lenticular lens. But due to the black space between the display panel pixels of the LCD and LED displays. When the pixels of the display panel are enlarged by the lenticular lens, the black space between the pixels is also enlarged, the brightness of the screen viewed by the user at different angles is changed due to the black space, and d in fig. 1 represents the distance from the focal point of the lenticular lens to the display panel. As shown in fig. 2 and 3, the ratio of the black space of the single lenticular lens is different in the enlarged portions of the display panel at different angles, and thus, after enlargement, the color composition may be different at each angle, which may cause glare.

As shown in fig. 2 and 3, the distance from the focal point of the lenticular lens to the display panel in fig. 2 is 0.2f (f is the focal length of the lenticular lens), and the distance from the focal point of the lenticular lens to the display panel in fig. 4 is 0.33f, and it can be seen from fig. 2 and 3 that if the distance d, that is, the distance from the focal point of the lenticular lens to the display panel, changes, the lenticular lens enlarges the pixels and black spaces on the display panel in different proportions. In the six observation directions, the regions enlarged from the first and fourth directions in the top-down sequence in fig. 2 are the intervals of ineffective non-light emission, so the light can be seen darkly, and the pixels enlarged in the other directions emit light brightly. In fig. 3, the areas just enlarged in the first, third, fourth and sixth directions from top to bottom are the intervals where the pixels do not emit light in black, so the light can be seen darker.

As shown in fig. 1, the distance d from the focal point of the light splitting device to the display panel can be configured to be 0.4f-0.6f, so that the brightness variation of the stereoscopic display device when viewed at different angles can be within a preset range.

Preferably, the distance d from the focal point of the light splitting device to the display panel may be configured to be 0.4f to 0.5 f.

Preferably, the distance d from the focal point of the light splitting device to the display panel may be configured to be 0.5 f.

Example two

Fig. 4 is a flowchart of a testing method of a stereoscopic display device with a light-splitting device according to a second embodiment of the present invention, the testing method is used for testing the stereoscopic display device with the light-splitting device according to the first embodiment of the present invention, and the testing method can be executed by a testing apparatus of the stereoscopic display device with the light-splitting device, and the apparatus can be implemented by software and/or hardware and can be integrated into an electronic device. As shown in fig. 4, the testing method of the stereoscopic display device with a light splitting device in this embodiment includes the following steps:

s410, adjusting the distance from the focus of the current width light splitting device to the display panel in parallel to obtain a candidate distance.

From the observation results of fig. 2 and 3, it is found that by changing the distance from the focal point of the lenticular lens to the display panel through testing so that the display panel is at a proper focal distance, it is possible to keep the influence of the black interval in each direction substantially the same, thereby avoiding the occurrence of glare due to the change in brightness.

The display panel can be a matrix array display, such as an LCD or an LED display screen, the light splitting device can be a lenticular grating, a naked eye 3D effect is achieved through the lenticular grating, and the width of a single lenticular lens is fixed. The adjustment of the distance from the focal point of the lenticular lens to the display panel can be expressed by a multiple of the focal length. Illustratively, the range of candidate distances may be chosen to be 0.1f-f, with each adjustment being incremented by 0.1f, in which case 10 candidate distances may be generated.

In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. Wherein, at least two brightness sensors are arranged at least two preset angles in front of the current width light-splitting device.

Wherein, the brightness detection at least two detection angles can be performed by arranging brightness sensors at different angles.

And S420, determining brightness values of at least two detection angles when brightness detection is carried out towards the current width light splitting device under the candidate distance.

Here, as shown in the example of fig. 2 and 3, the direction in which the line of sight is perpendicular to the display panel is taken as 0 ° at candidate distances of 0.2f and 0.33f, and the six directions are-30 °, -20 °, -10 °, and 30 °, 20 °, 10 °, respectively. The detection angle can redefine the setting, and the more the detection angle is set, the more accurately the brightness change condition at the candidate distance can be determined.

S430, according to the brightness values of the at least two detection angles at different candidate distances, screening the candidate distances to obtain a candidate distance with a brightness difference within a preset range as a target distance, and using the candidate distance to produce the stereoscopic display equipment based on the light splitting device and the display panel.

The preset range of the brightness difference can be that the brightness difference value between every two detection angles is less than 5%, the distance with the brightness difference within the preset range is found from the candidate distances to serve as a target distance, and the stereoscopic display device based on the light splitting device is produced according to the target distance.

In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. Wherein, according to the brightness values of at least two detection angles at different candidate distances, a candidate distance with a brightness difference within a preset range is obtained by screening from the candidate distances as a target distance, and the method comprises steps a1-a 2:

step A1, recording the brightness value variation trends of the current width light-splitting device at the at least two detection angles under different candidate distances.

And A2, determining the candidate distance with the minimum brightness value variation trend in the different candidate distances as the target distance.

And recording the brightness change trend of the current width light splitting device between the set detection angles under each candidate distance, and selecting the candidate distance with the minimum brightness change trend as the target distance. As shown in fig. 5, when the lenticular width covers two pixels, it can be found that when the size of the distance d is 0.5f, the influence of the black space on the brightness viewed at each angle is uniform. After the observation angles in fig. 5 are further expanded, the occupation ratios of the black intervals at the respective observation angles after being enlarged are counted, and as shown in fig. 6, when the candidate distance is 0.5f, the occupation ratio of the black intervals at the respective observation angles is always 20%, and therefore, the observation is performed at different angles without brightness change.

In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. Wherein, in case the candidate distance is determined, changing a preset sensor distance between the at least two sensors and the current width of the light splitting device; and recording the preset sensor distance with the minimum brightness value change trend under at least two preset sensor distances.

In an alternative of the present embodiment, it may be combined with one or more of the alternatives of the present embodiment. After the candidate distances are screened according to the brightness values of at least two detection angles at different candidate distances to obtain the candidate distances with the brightness difference within the preset range as the target distance, the method may include steps B1-B3:

and step B1, sending an observation instruction to an observer under the condition of the target distance, wherein the observation instruction is used for instructing the observer to observe the stereoscopic display result at least two detection angles respectively.

And step B2, receiving the stereoscopic display observation results of the observer at least two detection angles.

And B3, screening out the actual target distance from the target distances according to the stereo display observation result.

Under the target distance, under the condition that the minimum brightness change trend of each detection angle is met, the target distance which cannot realize three-dimensional display may exist in the target distance due to the fact that the light splitting device realizes naked eye 3D display characteristics. Therefore, the observer needs to actively observe the stereoscopic display result, and remove the target distance that cannot realize the stereoscopic display from the target distance set, so as to screen out the actual target distance that can realize the stereoscopic display.

According to the technical scheme of the embodiment, the distance from the focus of the current-width light splitting device to the display panel is adjusted in parallel to obtain the candidate distance; determining the brightness values of at least two detection angles when brightness detection is carried out towards the current width light splitting device under the candidate distance; according to the brightness values of at least two detection angles under different candidate distances, the candidate distance with the brightness difference within the preset range is screened from the candidate distances and is used as the target distance for producing the three-dimensional display equipment based on the light splitting device and the display panel, the dazzling condition caused by the brightness change when the naked eye 3D display panel realized by the light splitting device is watched at different angles can be avoided, and the technical effect of user experience is improved.
