Embodiment Construction

[0056] 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.

[0057] It should be noted that in the embodiments of the present invention, rows and columns are relative concepts. The rows described in the embodiments of the present invention are in the horizontal direction, that is, the row direction in this application; the columns are in the vertical direction, That is, the column direction in this application. However, since the pixels are arranged in a matrix, when the direction of observation is different, the row an...

Abstract

The embodiment of the invention provides a display drive method, a device and a display device and relates to the technical field of displaying. The display drive method is used for improving the display effect of the display device under the condition that a sub-pixel area is not changed. The method includes the steps that a to-be-displayed image signal is received; the to-be-displayed image signal is converted into a virtual pixel array formed by virtual sub-pixels at three colors, and a gray scale of each virtual sub-pixel is determined; three continuous sub-pixels are divided into a pixel unit in the horizontal direction, and a sampling area is arranged on the corresponding position of each pixel unit in the virtual pixel array; a gray scale of the sub-pixel of each color in the pixel unit is determined according to the gray scale of the virtual sub-pixel of each color covered with the corresponding sampling area. The display drive method is used for driving the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display driving method, device and display device. Background technique [0002] At present, displays are widely used in various electronic devices such as mobile phones, personal digital assistants (PDA), digital cameras, computer screens or notebook computer screens, and high-resolution displays have gradually become One of the important features of various electronic devices. [0003] The common pixel design of traditional displays is to use three sub-pixels: red, green, blue (English full name: Red, Green, Blue, abbreviation: RGB) sub-pixels to form a pixel, and then a plurality of the above-mentioned pixels are arranged in a matrix form. When a user watches a display device, his visual resolution is the physical resolution (actual resolution) of the display device. Therefore, in order to improve the display effect of the display device, it is necessary to adopt ...
