Problems solved by technology

However, this kind of LED display contains a G (green) component with higher luminance information and less chroma information, and two R (red) and B (blue) components with more chroma information and less luminance information. ; Studies have shown that the visual system's ability to distinguish brightness details is higher than that of color details, so this layout is not conducive to improving brightness resolution

Embodiment Construction

[0039] 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.

[0040] 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.

[0041] 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 four-lamp matrix layout, including one red (R) LED, one blue (B) LED and two green (G) LEDs arranged in a rectangle; here, the rectangular arrangement includes a rectangular permutations and square permutations. Among them, the two G LEDs are always located on the same diagonal of the rectangle. In addition, these four LEDs are not close...

Abstract

The invention relates to a sub-pixel downsampling based LED display method, a related structure and a device. The sub-pixel downsampling based LED display method comprises the steps of receiving an inputted original image; carrying out sub-pixel downsampling on the original image so as to acquire a plurality of pieces of sub-pixel color data corresponding to each LED display unit; carrying out color complementing treatment on the plurality of pieces of sub-pixel color data of each LED display unit so as to acquire a plurality of pieces of color complementing treated sub-pixel color data corresponding to the LED display units; and respectively driving a first color LED, a second color LED and two third color LEDs in the corresponding LED display unit according to the plurality of pieces of color complementing treated sub-pixel color data of each LED display unit so as to carry out image display. The LED display method provided by the invention carries out image display by adopting a specific physical sub-pixel layout, such as LED layout, and combining a sub-pixel downsampling technology and a sub-pixel color data color complementing treatment algorithm, thereby being capable of effectively improving the brightness and the resolution of a display screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an LED display method based on sub-pixel down-sampling, an LED structure, a display unit 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, and it is the bridge and link between information systems and human interaction. Its development and transformation have improved people's quality of life and promoted the development of other industries. Since the 21st century, LED display screens have been widely used for their advantages of energy saving, environmental protection, and high brightness, and can be seen everywhere in social life. LED display screens are different from CRT displays that rely on electron beam bombardment of fluorescent screens to emit light. They only have a fixed resolution, because their physical pix...
