There are two design methods for energy saving of led display: one is equiping led display with light sensor to adjust brightness. the other is using common cathode energy saving led display with energy saving IC and low votage power supply.

Due to the different raw material IC and chip, product specifications, supporting system and led brands, LED display has different prices.

Common cathode" refers to the use of common cathode power supply to power the LED display , that is, the R, G, B (red, green, blue) of the LED lamp beads are separated for power supply, and the current and voltage are accurately allocated to the R, G, B lamp beads.

The taxi LED display is a product that displays information on mobile cars using LED technology, GSM/GPRS technology, low temperature technology, anti-static technology, anti-interference technology, and car-mounted electronic technology. It is different from ordinary LED displays installed in fixed places.

The pole LED display cabinet is a metal structure with a small internal space. It is generally installed on the roadside. In the hot summer, the internal temperature can reach 80℃. Such a high temperature environment is an extremely terrible for an LED pole screen, so control the internal working temperature is very important.

After entering the summer, many places will experience high temperatures. Extremely high temperatures are fatal to LED displays. For users of LED displays, special attention should be paid to the impact of high temperatures on displays. So what are the specific harms of high temperatures to LED displays?
