LCD tester capable of testing various LCD modules

摘要

The LCD test apparatus which can test a variety of LCD module is described. LCD test device of the present invention, the main control section, key pads, subtitle fishermen and comprises a chamber into which examination tables are arranged, the main control unit stores a test program for the operation and control of the LCD test device, LCD module according to a test program, the evaluation of the test. The keypad should test drive the LCD device manually. Subtitle fisherman is a chamber (chameber), one per each connection. The main controller and sub-title fisherman is for example connected to the communication line such as RS232. Subtitle fisherman serves to transfer the pattern of the LCD module to each of the pattern generating unit intended for the test of the LCD module, which is assigned to each chamber. In the main control unit or the sub-title fisherman to generate the addresses of the LCD module. Inspection stage is recognizing the LCD modules, the address of the power supply, and the LCD module to supply power parameters of the LCD module, in which the pattern units pattern generator for generating pattern data in accordance with the data, connected to the pattern generating units provided in the main control unit It comprises an address recognition unit. Therefore, according to the LCD test device of the present invention, individually, a variety of the LCD module, and it can be tested by, or channel groups, even manually by in the event the main control portion fault operating the sub-title fisherman driven by the keypad It may drive the LCD test device, and does not require parts of conventional large capacity of power supply due to keep separate from a power supply for each LCD module.
