Embodiment 1

[0061] Such as figure 1 As shown, this embodiment provides a 3D display alignment system, including: a 3D display 100, an alignment processing module 102, and a color coordinate measurement module 104;

[0062] The above-mentioned 3D display screen 100 includes: a viewing area for the left eye and a viewing area for the right eye; for displaying a first color in the viewing area for the left eye and displaying a second color in the viewing area for the right eye; wherein the second color and said first color is a different color;

[0063] The above-mentioned color coordinate measurement module 104 is pre-set at the human eye viewing position of the above-mentioned 3D display screen 100, and is used to measure the color coordinates of pixels in the above-mentioned left-eye viewing area and the above-mentioned right-eye viewing area; wherein, the above-mentioned human eye viewing position Including: left eye pupil position, right eye pupil position and human eye 1 / 2 pupil dista...

Embodiment 2

[0096] This embodiment proposes a 3D display alignment method, which uses the 3D display alignment system described in Embodiment 1 above, and the execution subject is an alignment processing module, which is used to obtain the above-mentioned color coordinates measured by the above-mentioned color coordinate measurement module, And when it is determined that the above-mentioned 3D display screen needs to be aligned according to the above-mentioned color coordinates, an alignment operation is performed on the above-mentioned 3D display screen.

[0097] see Figure 4 As shown in the alignment method flow, the 3D display alignment method proposed in this embodiment includes the following specific steps:

[0098] Step 400: Obtain the first color coordinates of the pixels in the left-eye viewing area when the first color is displayed in the left-eye viewing area of ​​the 3D display screen and the second color of the pixels in the right-eye viewing area when the second color is dis...

Abstract

The invention provides a 3D display screen alignment system and method. A color coordinate measuring module and an alignment processing module are arranged in the system, the color coordinate measuring module measures a color coordinate of a color displayed on a 3D display screen, and when the alignment processing module determines that the 3D display screen requires alignment, an alignment operation is carried out on the 3D display screen. Compared with the process of determining whether alignment is carried out according to an image observation result by an alignment worker in related art, the manner of judging whether the 3D display screen requires alignment through the alignment processing module has the advantages that the alignment judging standard is objective, erroneous judgment is unlikely to be generated, the operation is simple, and the display effect of the 3D display screen after alignment is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a 3D display screen alignment system and method. Background technique [0002] Currently, 3D display screens are being increasingly applied to computing devices (eg, portable computers, mobile terminals). When assembling the 3D display screen, in order to ensure the display performance of the 3D display screen, it is necessary to calibrate the alignment between the 3D display panel and the 2D display panel in the 3D display screen. [0003] In the related art, the 3D display screen alignment system mainly includes two cameras and a computer connected with the two cameras, the two cameras are set up on the same horizontal line, and the horizontal distance between the two is set to the interpupillary distance of human eyes (about 65mm ), the vertical distance from the camera to the 3D display screen to be aligned is the optimal viewing distance of the final 3D display de...
