Title: DISPLAY PANEL, PRESSURE-SENSING TOUCH SCREEN AND DISPLAY APPARATUS
Abstract:
A display panel, a pressure-sensing touch screen and a display apparatus. A plurality of pressure-sensing touch control structures (4) are arranged between an array substrate (1) and an opposite substrate (2). The pressure-sensing touch control structure (4) comprises a first touch control electrode (41), a piezoelectric conversion layer (42) and a second touch control electrode (43). When the pressure-sensing touch control structures (4) are subject to the effect of a pressure, a pressure-sensing detection unit (5) determines the size of the pressure at a touch control position by detecting a change of a voltage value between the first touch control electrode (41) and the second touch control electrode (43), thus realizing a pressure-sensing touch control function. Pressure-sensing touch control structures are embedded in a display panel like this, so that a small modification is made on the structure design of the display panel, there is no limitation on an assembly tolerance, and better detection precision is realized.
