Detection system for intelligent liquid crystal display module

Abstract

The invention relates to a detection system for an intelligent liquid crystal display module. An FPGA (Field Programmable Gata Array) controller is respectively connected with an input power supply interface, an upper computer communication interface, an SD (Secure Digital) memory card, a liquid crystal display module interface and a touch screen interface. The liquid crystal display module interface and the touch screen interface can be used for driving liquid crystal display modules with various interface types and various touch screens; the FPGA controller can be in communication with an upper computer on a real-time basis and is used for sending a series of initial set instructions to the detected liquid crystal display module, and the detected liquid crystal display module displays adetection picture on the real-time basis; and the FPGA controller can also read and sequentially display the driving manner, the initial set instructions and the detection picture of the module from the SD memory card so as to realize the offline detection. The detection system has the advantages that the response speed is quick, the various interface types are supported, and the communication with the upper computer can be realized; and the detection system fulfills double protection functions, can quickly switch off the output when the output current exceeds the specified value, can protectthe detected module from breakdown and can be also prevented from burning out by a strong current.
