Abstract

The invention relates to a quality detecting device for a naked eye 3D (three-dimensional) device. A computer is respectively connected with a naked eye 3D display device and a stepping motor control circuit board; the stepping motor control circuit board is connected with a stepping motor A, a stepping motor B, a stepping motor C and a stepping motor D; the stepping motor A, the stepping motor B, the stepping motor C and the stepping motor D are respectively connected with an X shaft screw rod A, an X shaft screw rod B, a Y shaft screw rod and a Z shaft screw rod; a CCD (Charge Coupled Device) sensor is connected with the Z shaft screw rod; the Z shaft screw rod moves in an XYZ space; and the CCD sensor is connected to a video capture card. The quality detecting device for the naked eye 3D device has the advantages that the three-dimensional degree of the whole naked eye 3D display screen is measured by utilizing the CCD sensor, and the spectrum, contrast ratio and image deforming degree of left and right eye sub-screens displayed by the naked eye 3D device can be respectively detected.

Description

technical field [0001] The invention relates to a detection device, in particular to a naked-eye 3D equipment quality detection device. Background technique [0002] With the development of display technology and the demand of the market, the research on glasses-free 3D display devices has entered the stage of practical application. After the display devices are developed, their display effects must be tested. Only after the technical quality of the product is tested and qualified can it be put on the market, so as to ensure the quality of the product and realize the real productization. At present, only inspection equipment for two-dimensional display devices can be found on the market, and there is no naked-eye 3D equipment quality inspection system on sale. Ordinary two-dimensional display inspection equipment cannot complete the quality inspection of naked-eye 3D display equipment and its left and right eye sub-screens.
