Embodiment Construction

[0077] 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.

[0078] The transistors used in all embodiments of the present invention may be triodes, 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 control pole, one pole is called the first pole, and the other pole is called the second pole.

[0079] In actual operation, when the transistor is a triode, the contr...

Abstract

The invention provides a pixel circuit, a driving method, a display module and a driving method thereof. The pixel circuit includes a first pixel unit and a second pixel unit; the first pixel unit includes a first pixel electrode, a first control circuit and a first display driving circuit; the second pixel unit includes a second pixel electrode, a second control circuit and The second display driving circuit; the first display driving circuit and the second display driving circuit are connected to the same display control line; the first display driving circuit is the first pixel electrode under the control of the display control signal and the voltage of the first positive phase node providing the first display driving voltage; the second display driving circuit provides the second display driving voltage for the second pixel electrode under the control of the display control signal and the voltage of the second positive phase node. The present invention is beneficial to realize PPI (Pixels Per Inch, the number of pixels per inch), reduce charging differences, and realize narrow frame.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel circuit, a driving method, a display module and a driving method thereof. Background technique [0002] The existing MIP (Memory IN Pixel, a latch is set in the pixel) pixel structure includes a first pixel unit and a second pixel unit, the first pixel unit is connected to the first display control line, and the second pixel unit is connected to the second display Control line connection; the existing MIP pixel structure uses a large number of display control lines, which is not conducive to the realization of PPI (Pixels Per Inch, the number of pixels per inch), and is not conducive to reducing charging differences and simplifying the process of providing display control signals. The structure of GOA (Gate OnArray, a gate drive circuit disposed on an array substrate). Contents of the invention [0003] The main purpose of the present invention is to provide a pixel c...
