Abstract

The invention relates to the field of display, in particular to a sub-pixel rendering method and system based on an RGB triangular sub-pixel layout and a display device. The sub-pixel rendering methodcomprises the following steps: carrying out edge detection on RGB image data to obtain edge information; according to the edge information, carrying out kernel reconstruction on each filter kernel provided with a preset filter coefficient, and obtaining a reconstructed new filter coefficient; and obtaining a sub-pixel rendering RGB video or RGB image. In a DDI (Double Data Interchange) self-adaptive SPR (Surface Plasmon Resonance) method, after various edge types are effectively detected with STH (similar threshold) and DSTH (dissimilar threshold) using a filter directionally reconfigurable according to edge information, filter coefficients are effectively modified with edge information using a simple equation, and edge cracking in sub-pixel rendering is reduced by retaining edges.

Description

technical field [0001] The present invention relates to the display field, in particular to a sub-pixel rendering method, system and display device based on an RGB triangular sub-pixel layout. Background technique [0002] Today, due to the rapid development of display technology, AMOLED display devices are becoming more and more popular and become the main product in the mobile device display market. Although the resolution of AMOLED display devices continues to increase, a unit pixel is still composed of sub-pixels of the three primary colors of red, green, and blue, although more recent experimental devices have introduced more primary colors than conventional devices. [0003] Most traditional LCD display devices use RGB stripe sub-pixel arrangement to form a unit pixel composed of three main sub-pixels. On the other hand, AMOLED display devices are usually completed with various sub-pixel arrangements, such as RGB Delta, Pentile, Diamond patterns, etc. Therefore, the ...
