触控基板、触控显示面板以及显示装置
摘要：
本发明提供了一种触控基板、触摸显示面板及显示装置，属于触摸显示领域。其中，触控基板，包括设置在基板上的多个光感应薄膜晶体管，所述触控基板还包括：至少一个设置于所述光感应薄膜晶体管上方的压电感应结构，在所述压电感应结构被按压时，对应光感应薄膜晶体管的源极和漏极之间的导通电流发生变化。本发明的技术方案能够在不影响显示装置的开口率和功耗的前提下，提高触控的灵敏度和适用范围。
摘要（英）：

The present disclosure provides a touch substrate, a touch display panel and a display device which belong to a field of touch display. The touch substrate includes a plurality of photo-sensing thin film transistor arranged on the substrate, the touch substrate further includes a piezoelectric sensing structure arranged above at least one of the photo-sensing thin film transistors, and a breakover current between a source and a drain of the photo-sensing thin film transistor corresponding to the piezoelectric sensing structure is changed, when the at least one piezoelectric sensing structure is pressed.
