针对内嵌式触控显示屏中横条纹缺陷进行了原因分析,提出了相应的解决方案,如调节扫描电压、改变驱动模式、增强驱动能力等。实验结果表明,水平同步扫描模式下,内嵌式触控屏报点率达到120Hz,横条纹缺陷问题得到了改善,对提高显示质量有重要意义。
In order to solve the reason of the horizontal stripe defects in the in-cell touch screen, the corresponding solutions are proposed, such as adjusting the scanning voltage, changing the driving mode and enhancing the driving ability. The experimental results show that under the condition of horizontal synchronous scanning mode, the report rate of in-cell touch screen reaches 120Hz, the problem of horizontal stripe defects has been improved, which is of great significance to improve the display quality.
