Problems solved by technology

At present, the immaturity of high-density electronic assembly technology of LED tubes in China, the physical size of LED tubes and electronic components packaging, the complexity of circuits, and the high cost have hindered the improvement of the physical resolution of display screens.
Regarding the sub-pixel virtual display, although relevant research has shown that the number of pixels can be increased by 4 times through virtual display, or even a higher frequency doubling effect, but with the increase in the number of frequency multiplications, such as when the number of frequency multiplications reaches more than 10 times , it will bring blurred or trailing image display phenomenon
Therefore, in order to further improve the resolution of indoor small-pitch display screens, only relying on virtual display cannot achieve the desired effect.

Abstract

The invention relates to a virtual LED display module based on a three-color strip-type LED chip and a virtual LED six-fold frequency-doubling display method based on the three-color strip-type LED chips. The virtual LED display module comprises a three-color LED chip group formed by three-color strip-shaped LED chips; each three-color strip-shaped LED chip comprises at least three LED light emitting units; three-color strip-shaped LED chips are regularly arrayed such that a regular array of multiple equilateral triangles is formed by multiple LED light emitting units; and three LED light emitting units of three vertexes of each equilateral triangle are LED light emitting units have different primary colors. LED chips integrated with three colors RGB are prepared by adoption of light emitting material on the basis of GaN material. The LED chips are regularly arrayed to form small spacing arrays in which primary-color light emitting units are uniformly distributed at equal intervals. Therefore, physics resolution is increased. Meanwhile, six-fold scanning is performed through a sub-pixel sharing method so that virtual pixels are displayed and visual density is increased by six times. Sharpness of image display is raised.

Description

technical field [0001] The invention relates to the display field of LED display screens, in particular to a virtual LED display module based on three-color strip LED chips and a 6-fold frequency display method. Background technique [0002] As a digital image display medium, the LED display can display the image information of the video image source in real time. There are two key factors that affect the display effect of the LED display: one is the resolution of the LED display; the other is the display color and gray level of the display. Indoor LED displays generally adopt small-pitch LED displays with high physical resolution, and the LED dot pitch is below P2.5, mainly including P2.5, P2.0, P1.8, P1.5 and other specifications. At present, the display color and grayscale standards of LED display screens can meet the requirements, while indoor LED display screens have always had higher requirements for resolution, hoping to achieve higher display resolution.
