Problems solved by technology

When the sub-pixel rendering function processes the original fringe image, it will slightly change the sub-pixel value according to the type of OLED panel. It may be through the filter system in the driver IC to change the sub-pixel value. In this process, a sub-pixel rendering function Hundreds of thousands of images can be processed, for some images the processing results may be good, but for others the processing results will be poor, the original is that each image has different characteristics, it is impossible to make all processed by sub-pixel rendering function The processed images all have the quality close to the effect of natural light

Embodiment Construction

[0028] The following description of the embodiments will be more helpful for the public to understand the present invention, but the specific embodiments given by the applicant cannot and should not be regarded as limitations on the technical solutions of the present invention. Changes in the definition of the present invention and / or formal but not substantial changes to the overall structure shall be regarded as the protection scope limited by the technical solutions of the present invention.

[0029] like figure 1 shown, figure 1 is an ideal RGB pattern. The figure shows the positional relationship of sub-pixels in striped RGB and incremental RGB. In ideal RGB module 101, each sub-pixel is located at the center of the RGB shape. In striped RGB module 102, each sub-pixel is located in the center of the RGB shape. The pixels are all located at the same horizontal position, and in the incremental RGB module 103, each sub-pixel is distributed on the central position of the inc...

Abstract

The invention discloses a sub-pixel rendering method of an AMOLED display panel. The method includes the following steps: 1) setting a two-dimensional filter array with N rows and M columns, configuring filter coefficients, and performing sub-pixel rendering function; The preprocessed two-dimensional filter array of row A and column B; 3) Use the pattern detection module to detect whether there are any predefined special patterns in the input image; 4) The pattern detection module detects the predefined patterns, and each predefined pattern maps a Predefined coefficient set; 5) According to the result of pattern detection, change to one of the values ​​in the predefined coefficient set. The beneficial technical effects of the present invention are: improving the sub-pixel rendering function, using the position and shape of the sub-pixel to provide high-quality images for the viewer, so that the original image can be displayed on various AMOLED panels with an effect close to natural lighting .

Description

technical field [0001] The invention relates to a rendering method, in particular to a sub-image rendering method of an AMOLED display panel. Background technique [0002] OLED (Organic Light Emitting Diode) is a self-luminous element, any light source can be made with OLED. AMOLED is an OLED driven by an active matrix. The active matrix driving method can realize that each pixel has its own brightness and color. This form of OLED device set is suitable for high-resolution displays. [0003] OLED has become the most popular technology in the flat panel display market, because OLED display devices are used in smart phones and large-screen TVs, which will cost less than traditional liquid crystal displays, and have better display effects. OLED has better blacks and is clearer and sharper It can provide better contrast and clearer images. Because OLED has its own light source and does not need a backlight, it has low power consumption and can be made thinner and lighter. In a...
