摘要
针对TFT-LCD液晶显示器电源电路与驱动电路专业配件购买难、集成度高、维修成本高等问题,通过采用"二次配板"点屏技术,实现了用台式计算机电源供应器改装后替换原来液晶显示器电源板的新方法同时,采用ISP烧写技术,实现了驱动板的固件写入,解决了液晶显示器故障率较高的电源模块和驱动模块电路快速维修的问题。
Aiming at the difficulties in purchasing professional accessories of TFT-LCD power supply circuit and driving circuit, high integration and high maintenance costs, a second matching board technology is adopted to create a new method in replacing the original LCD power board with the power supply of the desktop computer. At the same time, the firmware writing of the drive board is realized by using the ISP technique. The fast maintenance problem of power supply module and drive module circuit with high failure rate of LCD is solved.
