Problems solved by technology

However, the content disclosed in the invention patent application is to eliminate color errors by constructing filters for each primary color of the original image, which may blur the image and make it difficult to achieve high-resolution and high-definition effects
[0006] Therefore, at present, in the field of LED display, there is no LED display method that can really combine the improvement of image resolution with the elimination of color errors to achieve high definition and high resolution.

Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] In order to facilitate the understanding of the present invention, the following two parts, the LED layout and the display method, will be described in detail respectively.

[0037] See figure 1 , the LED display unit array of this embodiment includes a plurality of LED display units (or LED pixels) P, which are applied to LED display screens, for example. A single LED display unit P adopts a three-color triangular layout, that is, three colors of red (R), blue (B), and green (G) are used as the primary colors, and the three LEDs of R, B, and G are arranged in a triangular layout. . In addition, these three LEDs are not close together in the spatial layout, but have a certain distance. Red LEDs, green LEDs, and blue LEDs can ...

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. LED (Light Emitting Diode, light-emitting diode) display system, as a new display technology, has gradually been accepted by the market due to its advantages of energy saving, environmental protection, and high brightness. It is 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 increasi...
