Embodiment Construction

[0023] The present invention will be further described below in combination with the accompanying drawings and specific embodiments.

[0024] (1) Provide the original image of each frame, such as figure 1 Shown is the original image of this embodiment, a small square in the figure represents a pixel on the LED display. Build the original template image with the same size as the original image, like image 3 As shown in , the original template image is a dot matrix pattern with black pixels and white pixels arranged alternately.

[0025] (2) The color of each pixel in the original image is mixed and superimposed with the color of the corresponding pixel in the original template image to synthesize a new image. After the pixels in the original image are superimposed with the black pixels in the original template image, the pixel brightness is weakened, and the LED light tube is nearly extinguished; after the pixels in the original image are superimposed with the white pixels i...

Abstract

The invention discloses an image processing based energy-saving method of an LED display screen. An original image is provided, an original template image is established, and the original template image includes a lattice graph in which black and white pixels are arranged in alternate; the color of each pixel in the original image is mixed with the color of the pixel in the corresponding position in the original template image to synthesize a primary new image; pixel values of red, green and blue of all the pixels in the original template image are inverted according to bits, a new template image is obtained, and the color of each pixel in the original image is mixed with the color of the pixel in the corresponding position in the original template image to synthesize a secondary new image; and a time interval t is set, and the primary new image and the secondary new image are displayed in a cyclic manner at time interval t. According to the method of the invention, power consumption of the LED display screen can be reduced, and the service life of the LED display screen is prolonged.

Description

technical field [0001] The invention relates to LED display screens, in particular to an image processing-based energy-saving method for LED display screens. Background technique [0002] The LED display is different from other display carriers. It can be assembled and spliced ​​arbitrarily according to the size of the actual site, and can realize ultra-large-scale display applications. In addition, it can cooperate with a wide variety of video processing equipment to achieve beautiful display scenes and Effect. Therefore, this kind of product can be widely used in various indoor and outdoor advertising, and with its unique display effect, it is the best in the same advertising screen industry and has a very broad market prospect. LED display has the advantages of high luminous efficiency, no pollution to the environment, energy saving, easy assembly and realization, etc. It will become an important way to improve the image of the city and enrich the cultural life of reside...
