Abstract

Embodiments of the present invention provide an AMOLED (Active Matrix/Organic Light Emitting Diode) pixel unit circuit and a display panel. According to the invention, a touch screen panel circuit is integrated in the AMOLED pixel unit circuit, and an AMOLED display panel with functions of a touch screen panel is produced. The AMOLED pixel unit circuit comprises a driving module for amplifying a sensing signal generated by a touch sensing module for a sensing signal output module to output, and driving a light emitting module; a light emitting control module for controlling the light emitting module to emit light; a threshold compensation module for compensating a threshold voltage of the driving module; a charging module for charging the threshold compensation module; the touch sensing module for generating a sensing signal and outputting the sensing signal to the driving module; and the sensing signal output module for outputting the sensing signal amplified by the driving module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an active matrix organic light emitting diode pixel unit circuit and a display panel. Background technique [0002] The touch screen is integrated in the liquid crystal box. The TSP in Cell technology is to make the TSP (Touch Screen Panel, touch screen) sensor Sensor and its driving circuit on the Array substrate by using the array Array process. Integrating the TSP Sensor into the liquid crystal display panel LCD (Liquid Crystal Display, liquid crystal display) panel can make the product thinner, have more functions, and effectively improve the reliability of the touch screen. [0003] Figure 1(a) and Figure 1(b) are the basic light-sensing TSP in Cell circuits in the prior art. In Figure 1(a), the Sensor uses photodiode D1 to sense light and generate leakage to detect touch signals. As shown in Figure 1(b), the Sensor uses the inductive capacitor C2 to sense light, and relie...
