Three color bar-shaped LED chip based virtual LED display module and six frequency doubling display method

Abstract

The invention relates to a three color bar-shaped LED chip based virtual LED display module and a six frequency doubling display method. The virtual LED display module comprises a three color LED chipset composed of three color bar-shaped LED chips; each three color bar-shaped LED chip at least comprises three LED light emitting units; the three color bar-shaped LED chips are regularly arranged, the multiple LED light emitting units form an M*N matrix; the LED light emitting units are arranged at equal intervals for a first spacing in the transverse direction and arranged at equal intervals for a second spacing in the longitudinal direction, and the first spacing is not equal to the second spacing; the LED light emitting units located in the first oblique line direction of the matrix havethe same primary color; the LED light emitting units located in the second oblique line direction of the matrix are three primary color LED light emitting units arranged by turns according to the specific sequence. Accordingly, RGB three color integrated LED chips prepared on the basis of GaN materials are adopted, virtual display is achieved through six-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 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.

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.
