[0002] At present, LED TV is a display device product that has emerged with the development of LED display technology. The high-definition self-luminous LED display can achieve functions such as ultra-small spacing and high-definition physical resolution, and has strong color expression capabilities, obvious grayscale and contrast advantages. It is fully suitable for displaying signals and images in various video interface forms.

[0003] However, existing LED TVs mainly appear in the form of display screens, which are generally accessed through a single video interface (such as VGA or DVI, etc.), and directly display the connected TV signal on the screen without any processing of the connected signal. As a result, existing LED TVs often only function as display screens, not TV functions, and the displayed picture effect is very poor, resulting in a poor user experience. In addition, existing LED TVs use a 1000M network cable physical layer custom transmission solution, which requires at least 16 network cables to transmit 4K ultra-high-definition signal LEDs for display. At the same time, the network cable physical layer is private and cannot be universally standardized, which increases the manufacturing cost of LED TVs and is prone to problems such as high bit error rate and slow response speed.
