Sep. 13, 2018

1 real pixel and virtual pixel. Like the p3.91mm Indoor Rental Led Display, the number of pixels in the indoor full color screen is also divided into real pixels and virtual pixels.

2 dies. Good die ensures the quality of the LED

3 package form. The LED surface of the indoor LED display has a single lamp, a sub-surface sticker, a three-ply-one-surface sticker and a three-in-one surface sticker, and the appearance is also different. The advantages of surface-mount package are large viewing angle, good luminous consistency, and easy automatic welding processing. It is the mainstream product of full-color LED screen, but now the price is relatively high; the single-lamp viewing angle is relatively small, the brightness is slightly higher, and the price is lower. The sub-surface sticker is actually a kind of single lamp. Single and sub-stickers are cheaper and are a transitional product.

4 density. Since the Indoor LED Display Module chip generates a large amount of heat and the control circuit has a high density, the dot density of the commercial full-color screen cannot be made high.

5 drive mode. The driving mode of the indoor full-color LED display is constant current driving, which adopts dynamic scanning mode (mainly 1/4, 1/8, etc.). In the case of the same die, the 1/4 scan circuit requires more, and the brightness is higher.
