压力传感器和制备方法、压力感应方法以及显示装置
摘要：
本发明公开了压力传感器和制备方法、压力感应方法以及显示装置。该压力传感器包括：衬底；第一电极；多个支撑部，多个支撑部设置在第一电极远离衬底的一侧，且覆盖第一电极的部分表面；弹性复合电极，弹性复合电极设置在支撑部远离第一电极的一侧，弹性复合电极、多个支撑部以及第一电极之间限定出可压缩空间，弹性复合电极以及第一电极之间通过支撑部以及可压缩空间绝缘；第二电极，第二电极设置在弹性复合电极远离第一电极的一侧；以及有机发光层，有机发光层设置在第一电极以及第二电极之间，并与第一电极以及第二电极之中的一个相接触。由此，该压力传感器具有功耗低、响应快、灵敏度高等优点。
摘要（英）：

A pressure sensor and a preparation method, pressure sensing method and display device. The pressure sensor comprises: a first electrode (200); at least two supports (300), arranged on a first surface of the first electrode (200); an elastic compound electrode (400) arranged at the side of the supports (300) away from the first electrode (200), wherein two adjacent supports (300) among the at least two supports (300), the elastic compound electrode (400) and the first electrode (200) define a compressible space (10), and the at least two supports (300) are made of insulated materials; a second electrode (500) arranged at the side of the elastic compound electrode (400) away from the first electrode (200); and an organic light emitting layer (600) arranged between the first electrode (200) and the second electrode (500) and in contact with one of the first electrode (200) and the second electrode (500). The present pressure sensor has the advantages of low power consumption, fast response, high sensitivity, and so on.
