Problems solved by technology

[0026] In order to solve the problems of wide data transmission bandwidth, high scanning rate, complex circuit, illegible handwriting when displaying single stroke characters, and the inability to flexibly select real mapping display mode and virtual pixel display through software settings in existing virtual display technology In view of these defects, the present invention obtains the method for displaying data of the primary colors corresponding to the light-emitting tubes on the display screen by preprocessing the three primary color data of the pixel points of the image source, so as to realize displaying more information on a display screen as small as possible, and the purpose is to provide A method of pixel multiplexing to improve display screen image resolution

specific Embodiment 1

[0050] Such as Figure 8 As shown in (3) and 8(4), the LED display tubes are arranged in such a way that one red, one green, and one blue LEDs are combined to form three primary color pixels, and the red, green, and blue tubes are at right angles and aligned vertically and horizontally. , Arranged evenly at equal intervals. Except for the edge, each luminous tube can form red, green and blue primary color pixels with two surrounding luminous tubes, and each luminous tube can be reused four times, corresponding to four different pixel points of the image source Corresponds to the base color.

[0051] Figure 8 (1), 8(2), 8(3), and 8(4) reflect the mapping relationship between the display screen and the image source. Among them, R, G, and B represent the red, green, and blue light-emitting tubes of the display screen; r, g, and b represent the red, green, and blue primary colors of the image source pixels.

[0052] The general expression of the mapping relationship between t...

specific Embodiment 2

[0070] Figure 8 (3), 8(4) Another luminous tube is arranged in the hollow position, and the three primary color pixels are formed by combining four adjacent luminous tubes, such as Figure 10 shown. The four light-emitting tubes are aligned vertically and horizontally, and arranged evenly at equal intervals, and the two light-emitting tubes on one of the diagonals have the same color. Except for the edge, each single tube can form three primary color pixels with three surrounding light-emitting tubes, and each single tube can be multiplexed four times, corresponding to the corresponding primary colors of four different pixel points of the image source.

[0071] Figure 11 (1), 11(2), 11(3), and 11(4) reflect the mapping relationship between the display screen and the image source. Among them, R, G, and B represent the red, green, and blue light-emitting tubes of the display screen; r, g, and b represent the red, green, and blue primary colors of the image source pixels.

Abstract

The present invention refers to method using pixel multiplexing to raise display screen image resolving, belonging to image display technology field. It contains using red, green, blue pixel point as displaying unit, uniformly distributing red, green, blue luminotron on LED display screen; determining display screen x line y column luminotron D with picture source mapping relation; to make preprocessing to picture source pixel point data; summarizing picture source adjacent four pixel point corresponding display screen luminotron relevant primary color data divided by four to obtain display screen corresponded luminotron primary color display data; sending obtained luminotron video data to display screen for displaying. The present invention realizes displaying more messages on small display screen with fine displaying effect than traditional virtual displaying and high displaying quality.

Description

technical field [0001] The invention belongs to the technical field of image display, and relates to a method for improving the display effect of an LED display screen, in particular to a method for improving the image resolution of the display screen by multiplexing pixels. Background technique [0002] The basic display unit of a digital image is a pixel. The quality of an image is mainly affected by two factors. One is the physical property of the image, that is, the physical pixel density, which is represented by image resolution or physical resolution; the other is the color property, which is the color level that a single pixel can express. , represented by image bits or gray levels. [0003] Currently, the most commonly used digital video image sources have a resolution of up to 1600×1200 (USXGA), commonly used 1280×1024 (SXGA), 1024×768 (XGA), 800×600 (SVGA) and 640×480 (VGA). The pixels of a digital video image source are composed of three primary colors of red, g...
