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

Abstract

The invention discloses a sub-pixel rendering method of an AMOLED (Active Matrix / Organic Light Emitting Diode) display panel, which comprises the following steps of: 1) setting a two-dimensional filter array with N rows and M columns, configuring filter coefficients, and executing a sub-pixel rendering function; 2) inputting a preprocessed A-row B-column two-dimensional filter array; 3) detecting whether the input image has any predefined special mode or not by using a mode detection module; 4) detecting predefined modes by a mode detection module, wherein each predefined mode maps a predefined coefficient set; and 5) according to the result of the mode detection, changing to one value in the predefined coefficient set. The method has the beneficial technical effects that a sub-pixel rendering function is improved, and a high-quality image is provided for a viewer by utilizing the position and the shape of the sub-pixel, so that the original image can be displayed on various AMOLED panels in an effect close to natural illumination.

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, and any light source can be made with OLED. AMOLED is an active matrix driven OLED. 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 smartphones and large-screen TVs, which will cost less than traditional LCD displays and display better. OLED has better black and is clearer and sharper The color 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 addition, OLED offers e...
