How to understand indoor outdoor LED display correctly

What is led display?.

Comparison of LED display screen and LCD display screen： The power consumption ratio of LED display screen and LCD display screen is about 1:10, LED display screen is more energy-saving; it has higher refresh rate and better performance in video; LED display provides a wide angle of view up to 160 ° and can display various text, digital, color images and animation information, and can play TV, ວິດີໂອ, ວີຊີດີ, DVD and other color video signals. The reaction speed of single element of LED display screen is 1000 times faster than that of LCD screen. It can also take care of under strong light and adapt to low temperature of – 40 ℃.

LED display maintenance
first: determine the type of hub used by the LED display module or LED display unit board, so that the interface definition of the wiring can be the same.

secondly: according to different types of LED display module or LED display unit board, send the corresponding program to the receiving card to ensure that the LED display module and LED display unit board are displayed under the correct program, which is the premise to find out the cause of the fault. ໂດຍທົ່ວໄປ, the model of the module or unit board will be printed on the PCB board.

finally: observe the LED display module or LED display unit board phenomenon, determine the initial fault. ຍົກ​ຕົວ​ຢ່າງ, common blind lights, string points, small squares, ແລະອື່ນໆ. Using the multimeter to find out the fault is mainly to use the above short circuit detection method to detect between the chip and the lamp pin.

outdoor LED display must pay attention to the use of LED display screen,
LED display installed outdoors, often exposed to the sun and rain, wind blowing dust cover, the working environment is bad. If electronic equipment is wet or seriously damped, it will cause short circuit or even fire, and cause fault or even fire, resulting in loss. The display screen may be attacked by strong electricity and strong magnetic field caused by lightning.

outdoor LED display varies greatly with the ambient temperature. When the outdoor LED display screen works, it will generate a certain amount of heat. If the environment temperature is too high and the heat dissipation is poor, the integrated circuit may not work normally, or even be burned, so that the outdoor LED display system can not work normally. The audience is wide, the visual distance is far and the vision is wide; the ambient light changes greatly, especially may be exposed to direct sunlight.
