Example Embodiment

[0027] see figure 1 , figure 1 It is a schematic diagram of the sub-pixel arrangement structure of a standard RGB display screen. In the standard RGB sub-pixel arrangement structure, red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B) are arranged in sequence, and the sub-pixels in each row are arranged in the same order.

[0028] see figure 2 , figure 2 It is a schematic diagram of a display panel using a Delta-type sub-pixel arrangement structure. In the delta-type sub-pixel arrangement structure, red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B) are sequentially arranged in a specific order. The arrangement order of the Delta-type sub-pixels is: in the arrangement structure of M×N sub-pixels, any sub-pixel in the i-th row and the j-th column, the i+1-th row and the j+1-th column sub-pixel, the i+2-th row and the j-th sub-pixel. The subpixels in the column and the subpixels in the i+3th row and the j+1th column have the same color, i=1,2,...

Abstract

The invention discloses a verification and display method of Delta-type arranged sub-pixel rendering. The method comprises the steps of 1, rendering sub-pixels of an original image with the pixel sizeof P*Q to obtain an RGB greyscale value matrix of the sub-pixels; 2, utilizing the mode of horizontally borrowing the sub-pixels to redistribute the RGB greyscale value matrix according to the arranging sequence of the Delta-type sub-pixels to obtain a Delta-type RGB greyscale value matrix with the pixel size of P*2Q; 3, reducing the Delta-type RGB greyscale value matrix with the pixel size of P*2Q into a Delta-type image with the pixel size of P*2Q and comparing and displaying the original image with the Delta-type image to complete verification. A standard RGB screen can be utilized to display a picture after the sub-pixels are rendered, and thus the feasibility of a sub-pixel rendering algorithm arranged by a display panel can be well verified.

Description

technical field [0001] The present invention relates to the field of image processing and display technology, more specifically to a display method for standard RGB screen verification sub-pixel rendering technology. technical background [0002] Displays are widely used, and display devices can be seen in electronic devices used by human beings in daily life. Conventional liquid crystal displays and OLED displays consist of two-dimensional arrays of pixels. Each pixel includes sub-pixels arranged in a certain order. The colors of the sub-pixels include red (R), green (G), blue (B) and the like. The sub-pixel colors of each pixel are mixed to display the color of the pixel, thereby displaying a color image on the display device. [0003] In today's display field, the sub-pixel arrangement of the display panel has changed. Taking the AMOLED screen as an example, the sub-pixel arrangement order of the display panel is no longer the traditional R, G, B order. Common sub-pi...
