Embodiment Construction

[0032] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0033] Such as figure 1 As shown, one embodiment of the present invention proposes a driving system for FPGA-based display module testing, the system includes an external main control device 1, a driving device 2 and a display module 3, and the external main control device performs a test on the driving device. Initial parameter setting, the driving device 2 drives the display module 3 to complete the multi-function test.

[0034] In a specific embodiment, the external master control device may be an ARM processor or a ho...

Abstract

One embodiment of the invention discloses a driving device, system and method for a display module test based on FPGA, and the device comprises a first interface processing module, a read-write control module, an image storage control module, an image output generation processing module, a register control module and a second interface processing module, the first interface processing module analyzes the initial parameters from the external main control equipment and sends the analyzed initial parameters to the register control module; the register control module is used for initially settingthe driving device according to the analyzed initial parameters; the image storage control module is used for storing the image data into a storage chip externally connected with FPGA through the read-write control module according to storage and reading rules of a to-be-displayed picture; and the image output generation processing module is used for reading the image data from the storage chip and sending the image data to the second interface processing module according to the image output rule.

Description

technical field [0001] The invention relates to the technical field of display and testing of liquid crystal modules. More specifically, it relates to a driving device, system and method for FPGA-based display module testing. Background technique [0002] As people's requirements for satisfaction with the use of mobile phones, tablets and other electronic products are getting higher and higher, and the maintenance cost of display modules of electronic terminal products is gradually increasing, the testing requirements of electronic terminal product manufacturers for display modules are also increasing. More and more, and the requirements are becoming more and more complex. A display module that can be used in products must be tested by multiple different testing procedures, including basic display function tests, brightness adjustment tests, power consumption tests, etc., as well as complex color differences accurate to the pixel level Tests, frame-accurate dynamic refresh...
