AI Technical Summary

Problems solved by technology

When the display screen displays a full TV picture, the dot matrix resolution of the display screen is much lower than the spatial frequency of the TV picture, which will produce a folding effect, resulting in a serious decline in image quality

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] combine figure 1 , figure 2 , image 3 and Figure 4 The outdoor all-weather giant full-color LED display array display unit generally adopts combined pixel technology, and its pixels are composed of high-quality red, green, and blue LED lights, and the three primary colors of color video display are provided through the color conversion matrix of the display control system. To select LED lights with appropriate brightness, the ratio of 1 red, 1 green and 1 blue can be adopted; the conventional array display unit is a 4*4 pixel array, arranged in a triangle. The ratio of 2 red 1 green 1 blue can also be adopted; the conventional array display unit is a 4*4 pixel array arranged in a square.

[0018] The development of LED lamp technology and technology makes the LED lamp have sufficient brightness even in the case of a large angle, resulting in excessive bri...

Abstract

A superresolution display method includes sampling picture matrix by using cardinal number line-cardinal number column, cardinal number line-even number column, even number line-cardinal number column, even number line-even number column; dicomposing picture matrix to be four picture submatrixes; using normal frame to display one picture of them and using recombined frame to display the other three pictures.

Description

1. Technical field [0001] The invention relates to a method for improving the resolution of a color array display system, in particular to a method for color array super-resolution display based on pixel recombination. 2. Background technology [0002] Among the public information publishing media, the outdoor all-weather giant full-color LED display screen has been widely used because of its special expression. However, in order to achieve a good display effect, the outdoor giant full-color display requires a very high display resolution, that is, a high number of dots. Due to the high cost of outdoor all-weather full-color LED display screens, the actual LED display screens currently produced only have relatively low pixels (such as: 320*240 dot matrix; 480*320 dot matrix; 512*384 dot matrix, etc.). In fact, this is the case where a full TV picture is sampled with a limited array of display units. When the display screen displays a full TV picture, the dot matrix resolut...
