Display screen dynamic control system and display screen

Abstract

The invention relates to a display screen dynamic control system and a display screen. The system comprises a receiving card and a first voltage stabilization power supply module. The receiving card is provided with a first pin, the first pin is connected with the enabling end of the first voltage stabilization power supply module, and the power supply output end of the first voltage stabilizationpower supply module is used for connecting a first display module. The receiving card is used for detecting whether a light-emitting signal for driving the first display module exists in display dataor not after the display data is received; and when the display data does not have the light-emitting signal for driving the first display module, the first control signal is sent to the enabling endof the first voltage-stabilizing power supply module through the first pin, so that the first voltage-stabilizing power supply module stops working, the standby loss of the first voltage-stabilizingpower supply module and the first display module is reduced, the waste of electric energy is reduced, and the temperature rise of a box body caused by the standby state of the first voltage-stabilizing power supply module is avoided.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a display screen dynamic control system and a display screen. Background technique [0002] With the rapid development of LED (Light Emitting Diode, light-emitting diode) display technology, large-scale integrated circuits and computer technology, LED display has become a new display medium. Compared with traditional colorful neon lights, pixel tube TV walls, For display media such as four-color magnetic flaps, LED displays are widely used due to their advantages such as high brightness, good dynamic image display effect, low failure, low energy consumption, long service life, various display contents, rich display methods, and high performance-price ratio. Applied to all walks of life. [0003] As we all know, the current LED display large-screen system is spliced ​​by small boxes, and its power supply method is column-by-column power supply, that is, each column is pow...

AI Technical Summary

Problems solved by technology

For example, a 2K screen receives a variety of video sources in practical applications, and it cannot guarantee full use of the large screen. There are often situations where there is no display in a certain corner box. Standby power consumption, the standby power consumption of a cabinet is about 30W, which not only wastes power, but also increases the temperature of the cabinet, making it inconvenient to operate the display module.
