P4 Indoor RGB Panel
Application
This technical manual applies only to indoor P4 (80* 40),constant current 1/20 scan with die-casting aluminum cabinet .
Product Description
- Indoor full color P4 1/20 scan module is composed of a pixel matrix, which is dominated by red LED chip, green and blue LED chip ,then fixed on the plastic
- This module contains drive IC and input buffer IC, connected to the LED display control system .It can display videos, images, texts
- Through OE signal to drive RGB’s drive IC, the screen can form 4,398,000,000,000 kinds of colors.
- The module can be assembled both in horizontal and vertical direction, so that customer can get different sizes display screen
- Module Characteristics:
- super bright LED and high quality plastic parts
- high contrast display can achieve good results
- Light weight: easy installation and removal
- can be a single point, single-lamp maintenance, low cost
- using constant current drive LED, light uniformity, low power consumption
- pixel pitch of 4.0mm, a total of 80 * 40 pixels , each pixel is composed of 1R1G1B
