Display panel virtual pixel multiplexing control method

Abstract

The invention discloses a virtual pixel multiplexing control method of a display panel, and belongs to the technical field of LED display panel control. The virtual pixel multiplexing control method solves the problems that an existing virtual pixel multiplexing control method causes image distortion due to large gray loss and is difficult to implement. A red chip, a green chip and a blue chip serve as a pixel unit, and the pixel unit is arranged in an inverted triangle and regular triangle alternate arrangement mode. According to the control mode, display of a frame of picture is completed through line-by-line scanning, and three-time and six-time multiplexing of virtual pixels is achieved. The method is suitable for the technical field of LED display panel control, and different virtual pixel multiplexing display effects are obtained through different line scanning processing modes of the display panel.

Description

technical field

[0001] The invention belongs to the technical field of LED display panel control, and in particular relates to a virtual pixel multiplexing control method of a display panel. Background technique

[0002] At present, high-density small-pitch LED, Mini LED, and Micro LED display technologies have become hot topics in the new display industry, and the display effect of products has become the focus of both users and the industry; regardless of brightness, contrast, and stability In the case of and uniformity, the factors affecting the image clarity of high-density LED display mainly include image spatial resolution, image display level resolution, pixel optical crosstalk, pixel edge fusion, etc. Medium is equivalent to the arrangement density of LED pixels.

[0003] Most of the LED display panels are arranged in a triangular arrangement. For example, the patent document CN113410259A discloses a "flip-chip spatial pixel arrangement structure and a display panel...
