Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a stereoscopic display device detection system and a stereoscopic display device detection method for detecting a stereoscopic display device. Background technique [0002] The imaging principle of stereoscopic image display technology is: based on the binocular parallax of the viewer, the left and right eyes of the viewer perceive the disparity map with image difference, and the viewer's brain forms a stereoscopic image based on the perceived image difference. [0003] Such as figure 1 As shown, the existing stereoscopic display device 1 includes a light-splitting device 11 and a display panel 12 , and the light-splitting device 11 is disposed on the light-emitting side of the display panel 12 . The display panel 11 provides a left view and a right view with image differences. Through the light splitting effect of the spectroscopic device 12, the left v...

Problems solved by technology

However, during the assembly process, assembly errors between the light-splitting device 11 and the display panel 12 cannot be avoided, resulting in that the light-splitting device 11 cannot be accurately attached to the display panel 12 according to the design requirements, resulting in crosstalk, poor stereoscopic display effects, and even Unable to meet stereoscopic imaging requirements and other issues

If the stereoscopic display device is not processed before leaving the factory, it will directly affect the user experience, thereby limiting the development of stereoscopic display technology

[0005] The prior art provides a liquid crystal slit grating stereoscopic display calibration method. By interrupting the first lead electrode, the initial state of each liquid crystal slit is corrected to be consistent. This stereoscopic display device calibration method is based on the liquid crystal slit grating and display However, during the lamination process, the assembly error between the liquid crystal slit grating and the display panel cannot be reduced, resulting in poor display effect of the three-dimensional display device after lamination

[0006] The prior art discloses a parameter measurement system of a stereoscopic display device. By detecting the projection image formed on the test plate when the stereoscopic display device displays a preset test picture, and analyzing the detection result, the stereoscopic display can be measured. The actual value of the grating parameters of the display device. When testing the parameter measurement system of the stereoscopic display device, the test board needs to be moved to the position corresponding to the position adjustment command. The operation is complicated, the test efficiency is low, and only the grating parameters can be obtained.
