Problems solved by technology

[0005] The display unit of the traditional LED display is powered by a linear power processor, but due to the limitation of its principle design, the main disadvantage of the linear power processor is that the linear power processor has high power consumption, low efficiency, and heat Serious and low power disadvantages
It is precisely because of the above shortcomings of the linear power processor that it restricts the overall luminous efficiency of the LED display as a whole.
And this is one of the main disadvantages of the traditional LED display

Description

technical field [0001] The present invention relates to an image display device, in particular to a display screen which structurally includes a signal input system, a signal control system and a signal display system, wherein the signal display system is composed of several LED pixel lamps. Background technique [0002] As we all know, with the development of society, LED light source, as a new type of light source, has been applied in many occasions due to its low power supply voltage, low power consumption, long life and no radiation. With the continuous improvement of its brightness in recent years, Especially with the emergence of ultra-bright LEDs, light-emitting diodes have been widely used. From traditional indoor instrument signal indications, they have gradually developed to be used in traffic lights, car lights, backlights, indoor and outdoor large-screen displays, and are currently being used Deep into the field of lighting. At present, the application of LED in...
