Light that is dead
Due to the welding technology used on LED display screens, the lamp beads have a certain dead light rate, which can cause the lamp beads to fall during production, transportation, installation, and later use. The lamp will not display once the lamp beads fall.
The resolution is average, and the near view effect is unclear
LED display screens are measured by the distance between dots. As a result of packaging limitations, the dot spacing of LED display screens cannot be as small as that of LCD at present, which results in a range of resolutions. The resolution is generally average, especially when viewed from a close distance.
Contrast is low
Compared to LCD screens, LED displays have similar color contrasts, so when they display a gorgeous image, the effect is not very bright, especially when the brightness decreases, the entire screen will become gray, not as bright as LCD screens.
Heat is high
During operation, the LED display screen generates more heat the larger the area. It is necessary to install an air conditioner in order to achieve rapid heat dissipation.
