Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] The transistors used in all embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain of the transistors used here are symmetrical, there is no difference between the source and the drain. of. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the gate, one pole is called the source, and t...

Abstract

The invention discloses an active matrix / organic light emitting diode (AMOLED) pixel circuit, a driving method thereof and a display device and relates to the technical field of display. According to the AMOLED pixel circuit and the driving method of the AMOLED pixel circuit, the integration level of an AMOLED driving circuit and an embedded type touch circuit can be improved. The AMOLED pixel circuit comprises a light-emitting module, a touch module, a control module and a driving amplification module. The AMOLED pixel circuit and the driving method of the AMOLED pixel circuit are used for manufacturing the AMOLED display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an AMOLED pixel circuit, a driving method thereof, and a display device. Background technique [0002] With the rapid progress of display technology, display devices with touch function are gradually becoming more and more popular due to their advantages such as visual operation. According to the relative positions of the touch panel and the display panel, the existing display devices with touch function can generally be classified into two types: on-cell touch panels and in-cell touch panels. Compared with the surface touch panel, the in-cell touch panel has thinner thickness and higher light transmittance. [0003] As for the existing display devices, Organic Light Emitting Diode (OLED) is a current-type light-emitting device, because of its self-illumination, fast response, wide viewing angle and the ability to be fabricated on a flexible substrate. and other characteristic...
