Embodiment Construction

[0030] The pixel virtual display method of the LED display screen of the present invention is to virtualize the actual pixel points of the LED display screen into new pixel points four times the actual pixel points and display them. The steps it includes are:

[0031] 1. Set the coordinates of the monochrome display positions X11, X12, X21, and X22 of actual pixels.

[0032] Set the coordinates of the actual pixel monochrome display positions X11, X12, X21, and X22 of the LED display screen respectively, and set the LED lights for displaying each monochrome at the upper left corner of each actual pixel. Taking the display screen of 3×3 pixels as an example, the method for setting the display coordinates of the LED lights at the four display positions of each actual pixel is explained respectively.

[0033] Such as image 3 As shown, the coordinates of the monochromatic display position X11 (such as the display coordinates of the green LED light) are set as: the screen starts f...

Abstract

The invention relates to a virtual display method of an LED display screen and a device thereof. The method comprises the following steps: a. the coordinates of monochromatic display positions X11, X12, X21 and X22 of actual pixel points of an LED display screen are respectively set; and an LED lamp for displaying each monochrome is arranged at the top left corner of each actual pixel point; and b. the position of each actual pixel point is divided into four equivalent cross-shaped symmetrical display areas; each display area is defined as the position of the new pixel point, and the color contained in the new pixel point is to the same as the actual pixel; and in the course of transmitting digital images, all the monochromes virtually computed in each new pixel are displayed through the LED lamp on the top left corner of each actual pixel. The device comprises a digital video source unit, an external memory, an FPGA chip, a scanning board and a display screen. Under the condition that the number of the LED lamps is not changed, the method and the device can increase the visual dot density of the display screen by a plurality of times, thus effectively increasing the quality of video images.

Description

【Technical field】 [0001] The invention relates to the technical field of LED display screens, in particular to a method and device for virtual display of pixels on an LED display screen. 【Background technique】 [0002] In digital display technology, the most basic unit of a digital image is a single pixel. The quality of a digital image is mainly restricted by two factors, one is the pixel density of a digital image, usually measured by resolution; the other is the color level that a single pixel can express, that is, the number of bits or gray degree level. For the same image, the display media with a resolution of 1024×768 and a color level of 32-bit true color will definitely have a better effect than a display medium with a resolution of 640×480 and a color level of 16-bit enhanced color. The LED display is a typical digital image display medium, so if you want to improve the display effect of the LED display, you usually start from two aspects. The first is to increa...
