Embodiment Construction

[0081] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0082] First, see figure 2 , is a schematic diagram of an embodiment of the present invention. As shown in the figure, a large light-emitting diode (LED) display 20 includes a plurality of pixels 22 , and each pixel 22 is arranged in an array, and there is a pitch 21 between adjacent pixels 22 . Wherein, the pixel pitch 21 varies according to the viewing distance designed for the large LED display 20 , and is generally about 5 cm to 10 cm, or even farther. For a full-color LED display, one pixel should include at least one red LED, one green LED and one blue LED. In addition, a white LED can be added as required.

[0083] The picture quality that the large LED display 20 can display is mainly determined by the amount of information that can be provided when displaying a picture. Generally speaking, the more pixels 22 of t...

Abstract

The invention discloses a display method of a large LED display. The large LED display comprises multiple pixels which are set in array, and a certain preset interval is kept between adjacent pixels. The display method comprises the following steps of: choosing the quantity of virtual pixels of an insert column between pixels of each column; choosing the quantity of virtual pixels of an insert row between pixels of each row; inserting a cross virtual pixel in the cross position of the vertical extending direction of virtual pixels of each column and the horizontal extending direction of virtual pixel of each row respectively; and displaying virtual pixel of each column, virtual pixel of each row and the cross virtual pixel by time sharing, wherein adjacent pixels share the corresponding chromaluminance of the virtual pixels. The invention presets the quantity of the virtual pixels to be inserted between pixels in each column and each row, utilizes pixels which are adjacent to each virtual pixel or within the identification scope of each virtual pixel to share the chromaluminance of the virtual pixels by time sharing, and improves the video quality and resolution of the large LED display as required.

Description

technical field [0001] The invention relates to a display method of a large light-emitting diode display, in particular to a high-quality display method of a large light-emitting diode display. Background technique [0002] Due to the continuous improvement of the manufacturing technology of light-emitting diodes (LEDs), the displayable color, brightness and lifespan of light-emitting diodes have been continuously improved, and their cost is relatively low. Many large-area or outdoor displays have been replaced by light-emitting diode displays. [0003] see figure 1 , is a schematic diagram of virtual pixels of the LED display 10 in the prior art. As shown in the figure, the LED display 10 includes a plurality of pixels 12 , and each pixel 12 includes two red LEDs 121 and 127 , a green LED 123 and a blue LED 125 respectively. [0004] It mainly makes the red LEDs 121 and 127 in each pixel 12 be arranged above and below the pixel 12 respectively, and the green LED 123 and t...
