The quality and price of the screen are mainly reflected in several aspects, which are several criteria for you to decide whether to buy the machine.
The screen size accounts for the vast majority of the price, generally including 32, 42, 47, 55, 65, 70 and 84 Inches, while the screen difference is 10 inches, the price will be more than 1000, and the larger the size, the greater the difference. After all, the larger the screen, the higher the stability requirements.
The power distribution cabinet plays a very important role in the large-size LED display screen. The display screen with power above 10kW needs to be equipped. It is very important to ensure the stability of screen power supply, prevent tripping and greatly improve the safety. Screen heat dissipation also plays a key role in anti-aging and service life. Keeping good body temperature and internal temperature can better delay the life of LED display screen, and the screen color will not change much over time.
Video processor is an important part of playing multi format media on the screen. The query and display software of computer-made advertising multimedia or touch all-in-one machine must have the support of multi format. The thickness of a single LED display screen needs to be thin, but generally, the LED will be thinner than the LCD, which is more luxurious and generous. At the same time, space needs to be reserved for assembly with infrared touch screen, computer host, casing, etc. when manufacturing touch advertising machine and all-in-one machine. The lightning arrester is special for outdoor, and it can be selected not to add indoor.
