Abstract

The invention relates to an LED display method, an LED display unit array, and a display control device. The LED display method comprises steps: an inputted original image is received; sub pixel down sampling is carried out on the original image to obtain multiple sub pixel color data corresponding to each LED display unit; complementary color processing is carried out on the multiple sub pixel color data of the multiple LED display units to obtain multiple sub pixel color data after complementary color processing for each LED display unit; and according to the multiple sub pixel color data after complementary color processing for each LED display unit, a first color LED, a second color LED and a third color LED which are arranged in a triangle mode in the corresponding LED display unit are driven for image display respectively. In view of the layout of physical sub pixels (LED) arranged in a one red-one green-one blue cellular mode, the sub pixel down sampling technology and the sub pixel color data complementary color processing algorithm are combined for image display, and the brightness resolution of the display screen can be effectively enhanced.

Description

technical field

[0001] The present invention relates to the technical field of LED display, in particular to an LED display method based on sub-pixel down-sampling, an LED display unit array and a display control device based on sub-pixel down-sampling. Background technique

[0002] Display technology is one of the most critical parts of the technology contained in the information industry. As a new display technology, LED (Light Emitting Diode) display system is gradually accepted by the market due to its advantages of energy saving, environmental protection and high brightness. Widely used in urban media, urban transportation and other fields.

[0003] The pursuit of display quality such as high-resolution display is the constant pursuit of the LED display industry.

[0004] Most of the existing LED display screens use three-color display technology, and only traditional sampling technology is used to improve the resolution, mainly by increasing the density and scale of p...
