Timing control system for testing t-con boards

Abstract

The invention discloses a timing control system for testing a T-con board, which includes a power input module, a protection module, a delay module, a control module, a voltage conversion module and a button input module, and the output terminals of the power input module are respectively connected to the voltage conversion The input terminal of the module is electrically connected with the protection module, the output terminal of the protection module is electrically connected with the input terminal of the delay module, the output terminal of the delay module is used for output voltage, and the control module is respectively connected with the voltage conversion module, the key input module and the delay module. The modules are electrically connected. The invention is a timing control system for testing a T-con board. By arranging a protection module, a delay module and a control module on a circuit board, compared with the prior art, it is possible to avoid the occurrence of welding wires The problem is that the connection is simple and convenient, which makes the whole system compact; at the same time, it can also avoid interference caused by too long welding leads, improve the stability of the test, and then improve the accuracy of the test.

Description

technical field [0001] The invention relates to the field of T-con board testing, in particular to a timing control system for testing a T-con board. Background technique [0002] With the development of the times, optoelectronic technology is constantly updated, and various optoelectronic products spring up like bamboo shoots after a rain. As we all know, when some optoelectronic products are powered on, the main chip in the board needs to read the EEPROM data, and after reading, send it to the PWM power chip, such as CS601, SY7611 and other chips to configure the registers, so that they can output VGL, VGH, GAMMA, etc. This process is also the initialization process of PCBA. The whole process takes about 70ms to 80ms. The I2C bus is busy during the initialization process, so it is not allowed to be interfered by the outside world. If there is another signal input at this time It will cause program confusion, so that the initialization process of PCBA will fail, and the sy...

Problems solved by technology

However, the existing three modules need to carry out their own welding wires to achieve electrical connection. The process is cumbersome, and it is not enough to make the whole system not compact enough. Prone to the problem of low delay accuracy
