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

An AMOLED pixel circuit, a drive method of same, and a display device. The pixel circuit and the drive method of same can enhance the integration between a built-in touch circuit and an AMOLED drive circuit. The AMOLED pixel circuit comprises a light-emitting module (11), a touch module (12), a control module (13), and a drive amplification module (14). The AMOLED pixel circuit is used to manufacture an 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 device, organic light emitting diode (OrganicLightEmittingDiode, OLED) is a kind of current-mode light-emitting device, because of its characteristics such as self-illumination, fast response, wide viewing angle and can be fabricated on ...
