Abstract

The invention discloses an LED (light emitting diode) display, an LED television, a communication method and a communication device. The LED display comprises an LED panel and a control circuit board. The LED panel is used for displaying images corresponding to video streams and is an array of a plurality of LED lamp panels in an (M*N) array form, wherein M refers to an integer larger than or equal to 1, and N refers to an integer larger than 1; each two adjacent LED lamp panels in each row of the array of the LED lamp panels are connected through a first communication interface. The control circuit board is used for distributing the video streams and is connected with the LED lamp panels in first columns of the corresponding rows in the array of the LED lamp panels through M second communication interfaces respectively. By the LED display, the LED television, the communication method and the communication device, the technical problem of high implementation cost caused by communication between the control circuit board and each LED light panel through network interfaces in related techniques is solved.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED display, an LED TV, and a communication method and device. Background technique [0002] Taking TV as an example, with the development of LEDs towards high density and small spacing, small and medium-sized high-definition LED TV panels (hereinafter referred to as LED panels) have been realized. However, LED TV is generally composed of LED control system and LED panel, which is different from other flat panel display technologies, such as LCD, plasma and other TVs. The TV panel of any size is a single complete panel, while the panel of LED TV is It is spliced ​​by many standard size LED light panels. This display technology, which consists of multiple LED light panels spliced ​​into a fixed-size LED panel, involves the LED control system and the LED light panels, as well as how to effectively transmit video streams and data between LED light panels. Command communication and other iss...
