Problems solved by technology

[0003] In the existing LED display screen, the components that consume the most power are mainly the driver chip and the LED lamp bead; according to the power control mode of the existing LED display screen, when the LED lamp bead is in the state , it will still supply power to the driver chip, so the driver chip will still consume power. At the same time, because the driver chip has a pre-charging circuit, when the driver chip is powered on, the LED lamp bead connected to it will withstand a large reverse voltage. The longer the LED lamp bead withstands the reverse voltage, the higher its voltage, so the service life of the LED lamp bead will be shorter

Abstract

The present invention relates to the technical field of electronic display equipment, and in particular to a method and device for reducing power consumption of an LED display screen, which includes: receiving and detecting a display control signal at the current moment; judging the display according to the display control signal Whether the screen is in the standby state, if it is in the standby state, record its state information, and judge whether the state information at the current moment is consistent with the state information stored at the previous moment, and if they are consistent, stop supplying power to the driver chip; The present invention acquires the display data signal, and identifies the content of the display data. When it is recognized that the current display screen is in the standby state, it disconnects the power supply to the drive chip, so the drive chip does not consume electric energy, which effectively The overall power consumption of the display screen during standby is reduced, energy consumption is saved, and at the same time, the reverse voltage received by the LED lamp beads is reduced, which improves the service life of the display screen.

Description

Technical field [0001] The present invention relates to the technical field of electronic display devices, and in particular to a method of reducing the power consumption of the LED display and a device that reduces the power consumption of the LED display. Background technique [0002] With the development of electronic technology, the LED display is widely used in home entertainment and outdoor advertisements due to its characteristics of high brightness, small size and convenient installation and maintenance. The LED display is composed of a plurality of LED lamp beads arranged; each LED lamp is coupled to a drive chip that is used to control the working state of the LED lamp bead. [0003] In an existing LED display, the most power consumption is mainly two parts: driving chips and LED lamp beads; according to the power control mode of the existing LED display, when the LED lamp is not illuminated It will still supply power to the drive chip, so the drive chip will still cons...
