Abstract

The invention relates to the technical field of LCD adjustment, and discloses a debugging device of an LCD logic board control module and a using method, a plurality of segment key source control circuits is connected with an LCD panel and a key matrix through a plurality of segment key source terminals so as to periodically output a signal for a frame, and the frame comprises a display output period and a key source output period, each electrical component in the plurality of segment key source control circuits. The LCD logic board control module edits by taking bytes as units, stores the edits in a read-write FLASH, uses a serial port with a Baud rate of 115200 to carry out communication transmission with a test mainboard, and is small in occupied space and high in sending and receiving speed. The invention further relates to an LCD testing method, the addressing mode adopted by the LCD testing method can be set in advance under a main program of a testing mainboard and can also be manually changed at any time, operation and writing are convenient, and the addressing mode between software is high in timeliness and good in confidentiality.

Description

technical field [0001] The invention relates to the technical field of LCD adjustment, in particular to a debugging device and a using method of an LCD logic board control module. Background technique [0002] Existing LCD test files are based on the FAT file system architecture and are stored in disk storage, which is based on the principle of electromagnetic conversion, and then read and write data through disk storage. For small memory storage types, not only waste storage space, There is also the disadvantage of slow reading and writing speed. At present, the management method of LCD test software is to store it locally, and the production personnel can use it remotely by extracting it by mail. Due to the huge amount of software, it is easy to cause problems such as lack of management and confusion in the use of software, which will affect the test efficiency. However, remote control has a high risk of information leakage, and the testers have a high error rate and low ...
