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.
As for the sub-pixel virtual display, although relevant studies have 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 doubling, it will bring blurred or dragged images. tail 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 three-color H-shaped LED chips and a two-time frequency display method. The virtual LED display module comprises a three-color LED chip group consisting of the three-color H-shaped LED chips and single-color LED chips; each three-color H-shaped LED chip comprises five LED luminous units; in the three-color LED chip group, the three-color H-shaped LED chips are arranged by m* n array, and the single-color LED chips are arranged among the adjacent three-color H-shaped LED chips of the m* n array along a first direction; and in the three-color LED chip group, the LED luminous units are arranged to form a plurality of triangles, and the distances among the optional adjacent LED luminous units along the first direction are equal toone another. RGB three-color-integrated H-shaped LED chips which are prepared by luminous materials in three colors on the basis of GaN materials are adopted, virtual pixel displaying is implemented by two-time scanning, and the image display definition is improved.

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 a three-color I-shaped LED chip and a double 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.
