Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the embodiments and accompanying drawings. Apparently, the described embodiments are only some of the embodiments, not all of them. In the case of no conflict, the following embodiments and technical features thereof can be combined with each other.

[0041] In the related art, the SPR function is usually implemented in the OLED display driver IC through a two-dimensional filter to change the value of each sub-pixel to fit each sub-pixel to a Delta-RGB type or RGBG type panel. Depending on the panel type, the filter coefficients are fixed, which apply to all input images. After setting the filter coefficients, all input images are affected by the filter coefficients of the 2D filter. The SPR processing effect is good for some input images and bad for some...

Abstract

The invention discloses a sub-pixel rendering method, a display device and a storage medium. The method comprises: inputting an original image; determining a preset image according to the original image; selecting a specific filter coefficient according to the determined preset image; and filtering the original image according to the specific filter coefficient, and rendering and displaying the original image to a display panel. According to the sub-pixel rendering method, the original image is input, the preset image is determined according to the original image, the specific filter coefficient is selected according to the determined preset image, and the original image is filtered according to the specific filter coefficient and rendered and displayed to the display panel, so that different filter coefficients can be used for different input images; different sub-pixel rendering is realized, and the SPR processing effect and the display effect of the image are improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a sub-pixel rendering method, a display device, and a storage medium. Background technique [0002] An OLED (Organic Light Emitting Diode) display panel has sub-pixels of various structures, namely red / green / blue, and the combination of positions and shapes of these sub-pixels will affect the image quality of the OLED panel. The SPR (Sub-PixelRendering, sub-pixel rendering) function enables the original image to be displayed naturally on various OLED panels. The SPR function is usually implemented in the OLED display driver IC with a two-dimensional filter to change each sub-pixel value, fitting each sub-pixel to a Delta-RGB type or RGBG type panel. The SPR function may process images well for some images but poorly for others. That is, since each input image has different characteristics, it is impossible to make all SPR processed images work well. Contents of...
