Abstract

The embodiment of the invention provides a pixel unit circuit for an organic LED of an active matrix, and a display panel; and is used for integrating a touch screen circuit in the AMOLED pixel unit circuit and manufacturing the AMOLED display panel having a touch screen function. The AMOLED pixel unit circuit comprises a driving module, a luminescence control module, a threshold compensation module, a touch induction module and an induction-signal output module, wherein the driving module is used for amplifying induction signals generated by the touch induction module, outputting by the induction-signal output module and driving a luminescence module; the luminescence control module is used for controlling the luminescence module to luminesce; the threshold compensation module is used for carrying out threshold voltage compensation to the driving module; the touch induction module is used for generating the induction signals and outputting the signals to the driving module and the induction-signal output module is used for outputting the induction signals 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...
