Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for full color uniformity of LED display screens, which solves the problem of LED screen full color uniformity correction by the existing detection equipment proposed in the above background technology. The disassembly and assembly steps of the display screen are cumbersome and time-consuming, and it cannot provide efficient heat dissipation for the LED display screen. High temperature easily affects the full color distribution of the LED display screen, and it is not very convenient. The problem of correcting the full color of the LED display

Abstract

The invention discloses an LED display screen full-color degree uniformity device, and relates to the technical field of LED display screens, in particular to an LED display screen full-color degree uniformity device. The device comprises a bottom cabinet and a red, green and blue LED array; a position limiting mechanism is installed above the bottom cabinet, and a frame is installed above the position limiting mechanism. A notch is formed in the front end of the bottom of the inner wall of the frame, a USB interface is formed in the notch, the red, green and blue LED array is located at the front end of the frame, and air guide mechanisms are installed on the left side and the right side of the rear end of the frame. The LED display screen full-color uniformity device is provided with theposition limiting mechanism, the linear lead screw motor pushes the lead screw guide sleeve to move in the direction of the horizontal center line of the containing frame through the adjusting lead screw, the pressing plates are close to each other through symmetrical distribution of the pressing plates, the pressing plates apply a clamping force to the frame, so the position of the frame can beeffectively limited, and the convenience of assembling and disassembling the frame can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a full-color uniformity device for LED display screens. Background technique [0002] Full-color LED display is a display method by controlling RGB semiconductor light-emitting diodes. Its general appearance is composed of many RGB three-color light-emitting diodes. Each pixel combination has RGB diodes. Off to display a full-color screen in different colors. A display screen used to display various information such as text, graphics, images, animations, quotations, videos, and video signals. [0003] When the existing testing equipment corrects the full color uniformity of the LED display, the disassembly and assembly steps of the LED display are relatively cumbersome, it takes a long time, and it cannot provide efficient heat dissipation for the LED display. , High temperature is easy to affect the distribution of the full color of the LED display, and it cannot c...
