Embodiment Construction

[0025] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0026] In order to solve the problem in the related technology, when the terminal is in the black screen gesture mode, the common line is only connected to the scan driving power supply in each scanning cycle to realize the scanning operation, which makes the residual charge in the common line exist. At this time, if the The common circuit is connected to the display reference power supply, which can easily lead to the polarization of the LCD panel, and problems such as screen flicker and afterimages, which affect the normal ...

Abstract

The invention discloses a display screen control method, device and display screen drive circuit, wherein the method comprises the steps that a present state of a terminal display screen is determined; if the display screen is at a black screen state, and it is determined whether or not a terminal is at a black screen gesture working state; if yes, a shared circuit is controlled to be alternatively connected with a scanning drive power and an earth point. According to the method, it is achieved that after a scanning operation is completed by the shared circuit, the shared circuit is connectedwith the earth point to quickly remove residual charges remaining on the shared circuit, thereby effectively solving the problem that screen flashing and ghost shadow occur when a follow-up display screen displays images, the reliable guarantee is provided for the displayed images of the display screen, and the user good use feeling is greatly improved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a display screen control method, device and display screen drive circuit. Background technique [0002] In order to realize the thinning and lightening of the control panel of the terminal equipment, an In-cell display screen has appeared in the electronic industry at present. Among them, In-cell refers to the method of embedding the touch panel function into the liquid crystal panel, that is, adding a touch integrated circuit (Integrated Circuit, referred to as FPC) on the main flexible circuit board (Flexible Printed Circuit board, referred to as FPC) of the In-cell display screen. IC) and key connectors, so that the original external touch panel components can be integrated with the LCD panel. [0003] At present, the structure of the In-cell display screen is usually a Full-Incell structure, which performs time-division multiplexing through a common line to rea...
