Correction method and system for OLED display image and character edge color cast, storage medium and processor

Abstract

The invention discloses an OLED display image and character edge color cast correction method and system, a storage medium and a processor, and the method comprises the steps: inputting sub-pixels line by line and one by one in a line scanning mode; acquiring a pixel value of a neighborhood pixel corresponding to the current sub-pixel; calculating color saturation values S and lightness values Y of all neighborhood pixels; performing feature recognition on the color saturation value S and the lightness value Y to obtain a matching result value and a matching degree value; judging whether the current sub-pixel needs to be corrected or not; if so, carrying out color mixing processing on the pixel value of the current sub-pixel, and taking the sub-pixel color mixing value as a corrected pixel value and outputting the corrected pixel value; if not, the pixel value of the current sub-pixel is reserved and output. No matter whether the SPR algorithm is applied to an AP chip of a mobile phone end or a DDIC driving chip of a module end, the problem of color cast generated on a screen when a character edge or an image edge contour is displayed can be always corrected through adjustment of the correction method provided by the invention.

Description

[0001] Technical neighborhood [0002] The present invention belongs to the field of integrated circuit design, in particular to a correction method for color casts of OLED display images and text edges, systems, storage media and processors. Background [0003] The present invention belongs to the integrated circuit design neighborhood, suitable for subpixels for SPR (sub pixel rendering, subpixel rendering) arrangement OLED (organic light emitting diode, organic light emitting diode) display. The OLED display arranged by SPR is the standard of all mid-to-high-end flagship mobile phones currently on the market. The main feature of SPR-arranged OLED displays is that the sum of the number of physical subpixels per line is two-thirds of the number of subpixels per line of Real RGB pictures. Therefore, the OLED display arranged by SPR can reduce the PPI while achieving ultra-high resolution performance, thereby reducing the difficulty of preparing the OLED display panel to improve the...

Problems solved by technology

The general scenario is that the mobile phone host cannot be replaced, but the OLED module can be replaced after damage

When an OLED module is replaced, the SPR arrangement type of the newly replaced OLED module or the preparation materials, physical size, and luminous efficiency of the R, G, and B sub-pixels may be different from the original OLED module.

In this scenario, since the SPR algorithm of the AP chip of the mobile phone host is applicable to the original OLED module, but not to the newly replaced OLED module, the newly replaced OLED module is often added to display text or image edges. There is a problem with color cast when contouring
