Embodiment 1

[0070] Please refer to figure 1 and figure 2 , figure 1 It is a flowchart of the overall implementation steps of a pixel rendering method in this embodiment, figure 2 It is a flow chart of implementation steps for judging whether the display mode of the pixel to be rendered is the text display mode in a pixel rendering method of this embodiment. From figure 1 and figure 2 It can be seen that a pixel rendering method of the present invention includes:

[0071] A pixel rendering method, comprising the following steps:

[0072] Step S101: Obtain the gray scale value of the RGB three primary color components of each pixel of the original image, and convert it into a normalized brightness value.

[0073] In this step, the gray scale value of the RGB three primary color components of each pixel of the original image is converted into a normalized brightness value by using a De-Gamma conversion method. Specifically, the following formula is used for calculation:

[0074] t...

Embodiment 2

[0118] The content of this embodiment is mostly the same as that of Embodiment 1, and the different parts are as follows:

[0119] The pixel rendering according to the text display mode in this embodiment is different from the method in Embodiment 1, which specifically includes:

[0120] Obtain the RGBW brightness values ​​of the first pixel, the second pixel, and the third pixel that are arranged adjacently from left to right in the same row of pixels, and use the first pixel as the pixel to be rendered, and calculate it according to the following formula :

[0121] W1 out =a 1 *W1+a 2 *W2+a 3 *W3, R1 out =a 1 *R1+a 2 *R2+a 3 *R3,

[0122] G1 out =a 1 *G1+a 2 *G2+a 3 *G3, B1 out =a 1 *B1+a 2 *B2+a 3 *B3,

[0123] Among them, a 1 、a 2 with a 3 is the weighting coefficient, and 0≤a 1 ≤1, 0≤a 2 ≤1, 0≤a 3 ≤1, a 1 +a 2 +a 3 = 1, W1 out , R1 out , G1 out and B1 out are the brightness values ​​of the rendered W sub-pixel, R sub-pixel, G sub-pixel and B...

Embodiment 3

[0144] Please refer to image 3 and Figure 4 , image 3 is a schematic diagram of the overall structure of a pixel rendering device 10 in this embodiment, Figure 4 It is a schematic diagram of the overall structure of the mode judging module 104 of a pixel rendering device 10 in this embodiment. From image 3 and Figure 4 It can be seen that a pixel rendering device 10 of the present invention includes:

[0145] The grayscale value acquisition module 101 is configured to acquire the grayscale values ​​of the RGB three primary color components of each pixel of the original image.

[0146] The first conversion module 102 is configured to convert the grayscale values ​​of the RGB three primary color components into normalized brightness values.

[0147] The second conversion module 103 is configured to convert the normalized brightness values ​​of the RGB three primary color components into corresponding RGBW brightness values.

[0148] The mode judging module 104 is co...

Abstract

A pixel rendering method and a pixel rendering device. The pixel rendering method comprises: obtaining a RGB brightness value of each pixel of an original image (S101), and converting the RGB brightness value into a RGBW brightness value (S102); determining whether a display mode is a text display mode (S103); if yes, performing rendering according to the text display mode (S104), or else, performing rendering according to an image display mode (S105); and converting the brightness value obtained after rendering into a gray-scale value and outputting the gray-scale value (S106). The pixel rendering method and the pixel rendering device can ensure that actual resolution is not reduced, and the loss of display details will not be caused.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display, in particular to a pixel rendering method and a pixel rendering device. 【Background technique】 [0002] With the continuous improvement of living standards and the continuous development of display technology, the shortcomings of the traditional three-color display system have gradually emerged, and it has been difficult to meet the growing needs of people. This is mainly reflected in that as the resolution of the display screen increases, the aperture ratio of the pixels will decrease, and the light penetration rate of the screen will also decrease, resulting in a significant increase in the power consumption of the backlight and the entire screen. [0003] Compared with the traditional RGB display, the RGBW display includes white (W) sub-pixels in addition to red (R) sub-pixels, green (G) sub-pixels, and blue (B) sub-pixels. The addition of white sub-pixels can be extremely Greatly impr...
