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 correction method. By interrupting the first lead electrode, the initial state of each liquid crystal slit is corrected. This correction method is operated before the liquid crystal slit grating is bonded to the display panel. However, in the bonding process, the assembly error between the liquid crystal slit grating and the display panel still cannot be reduced, resulting in poor display effect of the bonded stereoscopic display device
[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.

Embodiment approach 1

[0048] Such as figure 1 and figure 2As shown, the embodiment of the present invention provides a calibration device for a stereoscopic display device, which is used to obtain the calibration parameters of the stereoscopic display device 1 that meet the preset conditions. The calibration parameters provided in this embodiment are obtained by detecting the assembled stereoscopic display device 1 . Parameters corresponding to assembly errors. The correction equipment for the stereoscopic display device includes a support mechanism (not shown in the figure) and an image processing device (not shown in the figure), and the image processing device is installed on the support mechanism. The image processing device is used to obtain the stereoscopic image displayed by the stereoscopic display device 1 , and obtain correction parameters satisfying preset conditions according to the stereoscopic image, and the correction parameters are used to correct assembly errors of the stereoscop...

Embodiment approach 2

[0084] The calibration equipment of the stereoscopic display device provided in this embodiment is generally the same in structure as the calibration device of the stereoscopic display device provided in Embodiment 1, the difference is that, as figure 2 , Figure 5 as well as Figure 6 , the stereoscopic display device 1 is provided with a tracking unit 13, and the mounting part 31 is provided with a characteristic mark 33 that can be recognized by the tracking unit 13. When the tracking unit 13 tracks the characteristic mark 33, the control device 2 controls the image acquisition device 3 to obtain a stereoscopic image . The feature identifier 33 provided in this embodiment may be a plane cardboard or a three-dimensional head portrait with features that can be identified by the tracking unit 13 , which will not be described here. The tracking function of the tracking unit 13 is turned on, and when the tracking unit 13 tracks the feature mark 33 , the stereoscopic display d...

Embodiment approach 3

[0089] The calibration equipment of the stereoscopic display device provided in this embodiment is generally the same in structure as the calibration device of the stereoscopic display device provided in Embodiment 1, the difference is that, as Figure 5 , Figure 6 as well as Figure 9 , Figure 10 As shown, the second supporting part 5 includes a housing 55 , and the housing 55 is provided with a mounting part 551 , and the stereoscopic display device 1 is detachably mounted in the mounting part 551 . Since the image acquisition device 3 is an imaging device, including multiple precision devices, and the first support part 4 is composed of multiple components, in the production environment, processing debris affects the normal operation of the image acquisition device 3 and the first support part 4 , or the surrounding environment interferes with the operation of the image acquisition device 3, in order to ensure the stability of the calibration environment, the image acqu...
