Abstract

The invention discloses a display screen and a splicing screen. The display screen comprises a video processing panel, an LED module and a power module, wherein the video processing panel comprises one or more digital signal interfaces and one or more analog signal interfaces and is used for conducting signal processing and LED display control processing on received digital signals or analog signals and outputting video signals and control signals; the LED module is connected to the video processing panel and used for receiving the video signals and the control signals and controlling display of the video signals according to the control signals; the power module is connected to the video processing panel and the LED module and used for supplying power to the video processing panel and the LED module. By means of the display screen and the splicing screen, the technical problem that in relevant technologies, an LED display unit is singular in signal processing is solved, and the effect that the LED display screen integrates processing and displaying of multiple types of signals is further achieved.

Description

technical field [0001] The invention relates to the field of LED displays, in particular to a display screen and a splicing screen. Background technique [0002] At present, the pixel center distance of small-pitch LED display screens is less than 1mm. The smaller pixel pitch brings higher resolution under the same display area. For example, a 54-inch small-pitch LED display unit with a pixel center distance of 0.9mm Has reached 1280*720 (720p) high-definition resolution. At the same time, a number of LED manufacturers have successively launched 27-inch, 50-inch, 55-inch and more standard-sized small-pitch LED display units. From the appearance, the current small-pitch LED display unit is more like an LCD video wall display. [0003] As we all know, the display process of the LED display is to drive the LED light board to display images through the sending card / LED controller, receiving card, and scanning board. The sending card / LED controller is a digital signal processi...
