Abstract

The invention provides a pixel circuit, a pixel circuit driving method and a piezoelectric touch type organic light emitting display. The pixel circuit is of a 9T2C circuit structure, can collect and read touch signals while controlling an organic light emitting diode to emit light and can also amplify the touch signals and improve touch sensitivity. Furthermore, the brightness of a touch position will change when the piezoelectric touch type organic light emitting display is touched, so a better touch operation experience effect can be achieved.

Description

Technical field [0001] The present invention relates to the field of flat panel display technology, in particular to a pixel circuit and a driving method thereof and a piezoelectric touch type organic light emitting display. Background technique [0002] The organic light-emitting display uses organic light-emitting diodes (Organic Lighting Emitting Diode, OLED for short) to display images. It is an active light-emitting display. Its display method is similar to that of the traditional thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display for short). TFT-LCD) has different display modes, no backlight, and has many advantages such as high contrast, fast response speed, lightness and thinness. Therefore, organic light emitting displays are known as a new generation of displays that can replace thin film transistor liquid crystal displays. [0003] In recent years, touch technology has also developed rapidly. Touch electronic products can not only s...
