电子设备、压力感应触摸显示屏及其压力感应触摸屏
摘要：
本发明涉及一种电子设备、压力感应触摸显示屏及其压力感应触摸屏，压力感应触摸屏包括第一基材、驱动电极层、压电薄膜、第一承载体、触摸感应电极层及压力感应电极层，触摸感应电极层与压力感应电极层交替位于第一承载体的第三表面，因此触摸感应电极与压力感应电极层位于同一表面；驱动电极层通过分时的方式既作为触摸驱动电极层，又作为压力驱动电极层，所以能够同时感测触摸动作和压力的大小。相较于传统的方案，压力感应电极层距离触摸面的距离更近。当触摸面发生触摸动作时，可以有效保证检测到的压力信号的强度，而且驱动电极层作为触摸和压力感应的共用驱动电极层，减少了一层电极层数，有利于减小压力感应触摸屏的整体厚度。
摘要（英）：

The invention relates to an electronic device, a pressure induction touch display screen and a pressure induction touch screen of a pressure induction touch display screen. The pressure induction touch screen comprises a first substrate, a driver electrode layer, a piezoelectric film, a first bearing body, a touch induction electrode layer and a pressure induction electrode layer, wherein the touch induction electrode layer and the pressure induction electrode layer are alternately located on a third surface of the first bearing body, so that the touch induction electrode layers and the pressure induction electrode layers are located on the same surface; and the driver electrode layer serves as not only a touch driver electrode layer but also a pressure driver electrode layer in a time division manner, so that a touch action and a pressure value can be sensed at the same time. Compared with a conventional scheme, the pressure induction electrode layer is closer to a touch surface. When the touch action is generated on the touch surface, the intensity of a detected pressure signal can be effectively ensured; and the driver electrode layer serves as a shared driver electrode layer for touch and pressure induction, so that an electrode layer is removed and the overall thickness of the pressure induction touch screen can be reduced.
