Technical Field

[0001] The present invention belongs to the technical field of display screens, and in particular relates to a Mini LED display screen that is convenient for improving brightness. Background Art

[0002] Mini LED display is a display device that uses Mini LED backlight technology. Mini LED is a micro light emitting diode, which is much smaller than traditional LEDs, usually between 50 and 200 microns. This size advantage allows more LED beads to be accommodated in a screen of the same size, thereby greatly improving the screen brightness and contrast.

[0003] However, with the rapid iterative development of LED display application technology, the requirements for LED screens, LED devices, and LED RGB chips are getting higher and higher; among them, the brightness requirement for the screen is the most prominent. However, the ultimate factor for the insufficient brightness of the screen is the low brightness of the LED R chip. Due to its materials, production capacity and other factors, the LED R chip has low luminous efficiency and high cost. Technologies such as quantum dot color conversion and Micro LED are not yet mature and cannot replace the traditional LED R chip market, so staff need to improve them. Summary of the invention

A mounting plate 3 is fixed to one side of the inner wall of the display screen body 1, and an LED lamp bead array 4 is fixedly connected to the surface of the mounting plate 3, including an LED R chip, an LED G chip, and an LED B chip, to provide a high brightness and high contrast display effect. The LED R chip is controlled by a PCB circuit board 5 to use a low scan, and the LED The G / B chip uses high scanning to reduce the number of driver chips and reduce costs while maintaining the high brightness performance of the display screen. The display scheme is implemented using the 6-pin LED device SMD process or COB process to ensure that the R, G, and B chips are controlled separately and do not interfere with each other, thereby realizing convenient brightness adjustment. A plurality of heat sinks 9 and a battery assembly 10 are fixedly connected to the back of the display screen body 1 and electrically connected to the power supply assembly 8 to ensure effective heat dissipation of electronic components and stable power supply. Wind energy is generated by setting the driving mechanism 12 and the fan blades 15, and the ventilation frame 16 and the conical air outlet duct are designed to quickly cool down and dissipate heat to protect the electronic components inside the display screen body 1.

[0045] Working principle: When in use, the PCB circuit board 5 is designed to make the LED R chip use low scanning and the LED G / B chip use high scanning. Compared with LED RGB, which all use low scanning, the number of driver chips is reduced by about 2 / 3, the performance of the LED RGB chip is maximized, and the performance of a high-brightness display screen is achieved at a lower cost, keeping the service life of the display screen unchanged. Because the scanning numbers of the R and G / B chips are different, the display solution can be implemented using a 6-pin LED device SMD process or a COB process. The reason is that the R, G, and B chips need to be controlled separately without interfering with each other. The heat dissipation plate 9 facilitates the heat dissipation of the electronic components inside the display screen body 1.

Due to the unique design of the tapered air outlet duct, when the wind energy is blown out, the air is compressed by the tapered air outlet duct, so that the discharged air is rapidly cooled down, thereby quickly cooling and dissipating the electronic components inside the display screen main body 1. The staff connects the servo motor 21 to the power supply, and the output end of the servo motor 21 drives the transmission rod to rotate, and the transmission rod drives the driving gear 22 at one end to rotate, and the driving gear 22 drives the transmission gear 23 meshingly connected on the surface to rotate, and the transmission gear 23 drives the top support rod 19 to rotate, thereby driving the display screen main body 1 at the top of the support rod 19 to adjust the angle.
