Embodiment Construction

[0052] 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.

[0053] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. 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 first pole, and the other pole is called the second pole. In actual operation, the first electrode may be a drain, and the second electrode may...

Abstract

The invention provides a driving module, method and display device of a pixel circuit. The driving module of the pixel circuit includes: a signal generation unit, which transmits the read control signal to the corresponding row read control line, and transmits the gate drive control signal to the gate drive circuit; The gate driving control signal generates a plurality of gate driving signals to control multiple rows of gate lines to be turned off during the reading period; one gate driving signal corresponds to one row of the gate lines. The invention solves the problem that the influence of gate line and data line timing on the photoelectric module cannot be avoided in the prior art.

Description

technical field [0001] The present invention relates, in particular, to a pixel circuit driving module, method and display device. Background technique [0002] The existing pixel compensation unit based on OLED (Organic Light Emitting Diode) display includes: a photosensitive module, which is used to convert the light signal sent by the pixel unit into a corresponding electrical signal; a read control module, which is used to read Under the control of the read control signal on the control line, the electrical signal is transmitted to the corresponding column read line during the read time period; and the data voltage compensation module is used to adjust the corresponding column data line according to the electrical signal. Compensate for the data voltage on the However, the existing pixel compensation unit cannot avoid the impact of the gate line and data line timing on the photoelectric module, and cannot dynamically adjust the integration time, making the compensation ...
