Embodiment Construction

[0040] The present invention provides a method for driving an image signal and a display device. In order to make the object, technical solution and advantages of the present invention clearer and clearer, the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0041] In order to achieve the purpose of reducing the high-speed changing current variation when the display device is displaying, improving signal integrity, and preventing EMC interference, the present invention provides a driving method for an image signal and a display device, which divides the display screen into a plurality of The first-level area; receive the data sent by the front-end video processing circuit, and obtain the coordinates of the data according to the position of the row and column of the signal; confirm the first-level area to which the data belongs according to the coordinates of the data; distribute all the data equally The data switchi...

Abstract

The invention provides an image signal driving method and a display device; a display screen is divided into a plurality of first-class areas; signals and data sent by a receiving front end video processing circuit determine the coordinates of the data according to the sequential logic of the signals; the first-class area that the data belongs to is determined according to the data coordinates; data switching points in the first-class area are uniformly distributed; and the data switching points send the data to the first-class area. The current variables which are changed at high speed can be reduced by dividing the picture on the display screen into the plurality of the areas, so as to improve the completeness of the signals, and prevent EMC interference and other problems.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a method for driving an image signal and a display device. Background technique [0002] In data display driving, each frame of data is continuously sent to the driving stage, and the driving circuit directly drives the display device to display the data. From the current driving characteristics of different display devices: displays that include a whole screen of data and are updated at the time of frame switching, such as LCD (LiquidCrystal Display, liquid crystal display) displays, and displays that update data line by line in the frame, such as (LEDLight Emitting Diode, light-emitting diode) display, etc. [0003] As the size and resolution of the display device become larger and larger, the amount of data to be updated in each frame becomes larger and larger. Each display pixel corresponds to a driving unit, and each driving unit requires a certain driving ...
