Description
本發明係關於一種觸控與顯示驅動整合系統之顯示效果優化方法及採用該方法之觸控顯示面板，利用本發明之顯示效果優化方法可避免顯示面板出現水平細線瑕疵（H-line）的情況。The invention relates to a display effect optimization method of a touch and display drive integration system and a touch display panel using the method. By using the display effect optimization method of the present invention, a horizontal thin line defect (H-line) can be avoided in a display panel .
隨著行動裝置的普及與蓬勃發展，觸控顯示裝置已經成為其中不可缺乏的零組件之一。傳統的系統架構中，觸控與顯示功能分別由觸控晶片與顯示晶片獨立控制，而觸控與顯示驅動器整合系統（Touch and Display Driver Integration，TDDI）藉由把觸控晶片與顯示晶片整合進單一晶片之技術，不但減少了元件的數量，使螢幕變得更薄、也能提升面板透光率，使電池續航時間相對變得更長。With the popularity and vigorous development of mobile devices, touch display devices have become one of the indispensable components. In the traditional system architecture, the touch and display functions are controlled independently by the touch chip and the display chip, respectively. The Touch and Display Driver Integration (TDDI) system integrates the touch chip and the display chip by The single chip technology not only reduces the number of components, makes the screen thinner, but also improves the light transmittance of the panel, making the battery life longer.
使用TDDI系統之顯示面板在進行掃描時，通常是在顯示一定數量的行數後，插入部分觸碰掃描。然而，在此種掃描方式期間，正常的顯示會被觸碰掃描打斷，且源極線上的電壓會產生變化，因此當觸碰掃描完成後再繼續顯示時，由於源極線上的起始電壓與非TDDI掃描的情況不一致，使得觸碰掃描完成後的下一行顯示出現水平細線瑕疵（H-line）的異常情況。When the display panel using the TDDI system is scanning, usually after a certain number of lines are displayed, the insertion part touches the scan. However, during this scanning mode, the normal display will be interrupted by the touch scan, and the voltage on the source line will change. Therefore, when the display is continued after the touch scan is completed, the initial voltage on the source line It is inconsistent with the non-TDDI scan, so that the next line after the touch scan is completed shows an abnormal situation of horizontal thin line defects (H-line).
為解決上述問題，本領域亟需一新穎的觸控與顯示驅動整合系統之顯示效果優化方法，以避免前述顯示面板之缺陷。In order to solve the above problems, a new method for optimizing the display effect of a touch and display driving integration system is urgently needed in the art to avoid the defects of the foregoing display panel.
