Display module light-on test device and method

Abstract

The invention discloses a display module light-on test device and a display module light-on test method. The device is used for performing light-on test on a to-be-tested display module and comprises a memorizer, a peripheral circuit and a field programmable gate array chip, wherein a microprocessor and a display interface controller are integrated in the field programmable gate array chip; the microprocessor is used for outputting initialization information; the microprocessor is connected with the display interface controller; and the field programmable gate array chip is connected with the to-be-tested display module through the display interface controller to output the initialization information to the to-be-tested display module, so that the to-be-tested display module is subjected to initialization operation, processed picture data is output to the to-be-tested display module, and the to-be-tested display module is subjected to light-on test. By the method, a hardware part of the light-on test device can be simplified, the design of the peripheral circuit is reduced, the use amount of electronic components is reduced, the stability of the light-on device is improved and maintenance of research staff is facilitated.

Description

technical field [0001] The invention relates to the display field, in particular to a display module lighting test device and method. Background technique [0002] At present, small-size panel manufacturers will conduct corresponding functional tests on the mobile phone module after the mobile phone panel is assembled, such as the quality of the module optics, the overall power consumption of the module, and gamma debugging. These related tests require a module lighting test platform to be implemented. Most small-size panel manufacturers use a large number of components in the lighting test device, which is relatively expensive and easily affects the progress of module testing. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a display module lighting test device and method, which can simplify the hardware part of the lighting test device, reduce peripheral circuit design, reduce the number of electronic componen...
