Advantages and disadvantages of grid LED display screen

Grid transparent  LED display screen is a new product that led technology is applied to the field of outdoor decorative lighting. Its working principle is composed of two parts: drive and control. Small LED square lamp is used as the light-emitting display unit. LED screen or LED billboard is formed by several square LED pixel units arranged in a certain matrix, and connected with video controller and computer. Next, we will discuss the advantages and disadvantages of grid LED display application.

1. Benefits of LED
LED is a semiconductor that can convert electric energy into visible light. Its characteristics are as follows
a. High efficiency and low energy consumption.
b. Light quality is good, because there is no ultraviolet and infrared in the spectrum, so there is no heat, no radiation, LED is a typical green lighting source.
c. Long life, luminous flux attenuation to 50% of the nominal life of 100000 hours.
d. The working voltage of the unit is about 1.5V ~ 5V, and the working current is about 20mA.
e. Green environmental protection, recyclable waste, no pollution; Unlike fluorescent lamps, which contain mercury.
f. The control is flexible, the light can be adjusted by adjusting the current, the combination of different light colors can be toned, and the timing control circuit can achieve a variety of dynamic changes.
These advantages make LED be considered as an ideal green light source, which has been more and more successfully applied in the field of engineering lighting and display. Compared with the traditional neon lamp, incandescent lamp and halogen lamp, LED has obvious advantages in color performance, lighting control, environmental protection and energy saving
LED pixel combination can form a dynamic and ever-changing visual effect.
2. Problems to be solved
At present, disco bar has a wide variety of lighting and control systems. If we want to construct a shocking full-color display wall as the environmental background, the light source should give priority to LED, rather than the traditional thermal radiation light source and gas discharge light source with large power consumption, high control difficulty, short service life and poor system safety factor.
Design concept: environmental background design novel, environmental protection, under the control of computer color changes, reflecting the characteristics of high-grade disco bar. Through the overall point-to-point control, cascade data transmission and system instant response, the overall unified control of LED lights inside the bar can be achieved, and the corresponding tone (such as displaying a simple change picture) and atmosphere can be adjusted.
3. Design thinking
LED screen display involves optics, electricity, control, machinery, materials, art and other multidisciplinary technology. On the premise of ensuring the lighting function, the design achieves the visual effect consistent with the environment.
