Technical field

The present invention relates to liquid crystal display field, in particular to a kind of liquid crystal display optical property automatic test device and method.

Background technique

Vehicle-mounted liquid crystal screen needs to assess optical parameter after designing and producing out, using CA310 instrument to liquid crystal The measurement of screen is important evaluation measures, and the method for measurement is usually that 9 points on liquid crystal display is taken to measure.Usually by people Hand averagely takes a little, as shown in Figure 1, measuring in hand-held CA310 camera lens to 9 points, but often manpower takes a precision not high, more Cumbersome, time-consuming.

The uniformity of measurement liquid crystal display is to take 9 positions to carry out taking a measurement liquid crystal display using the camera lens of CA310 instrument, The data of comprehensive 9 points are averaged；But measured since manpower can not uniformly choose 9 points on a display screen, it may It will lead to measurement result inaccuracy, be unable to satisfy experiment demand.

Summary of the invention

The embodiment of the present invention is designed to provide a kind of liquid crystal display optical property automatic test device, so that test knot Fruit is more accurate, more efficient.

A kind of liquid crystal display optical property automatic test device provided in an embodiment of the present invention, including telecontrol equipment and installation Camera and testing lens on the telecontrol equipment further include video signal source, liquid crystal display to be measured and power supply, the movement Device, camera, testing lens and video signal source are connect with the processor of operation test software, and the video signal source drives It moves the liquid crystal screen to be measured and shows test pictures, the power supply is the liquid crystal display to be measured, video signal source and processor power supply.

Optionally, the camera is using high-definition camera for capturing display screen.

Optionally, the testing lens are used to capture the liquid crystal parameter of liquid crystal display to be measured using CA310 equipment.
