southbound indoor high-end SO-P4 LED display module can be widely used in conference rooms, command and dispatch, live studios, monitoring centers, radio stations, school classrooms, exhibition halls, security, stations, airports, hospitals, tourist attractions, TV studios and other high-end scenes.
1. The indoor full-color display effect is more clear and delicate, and the resolution can reach more than 1080P; Achieve high refresh rate, high gray scale and high lamp utilization rate; No residual shadow, anti-” caterpillar “, low power consumption, low surge and other functions;
2. Indoor full-color display is mainly composed of red LED chips, green LED chips and blue LED chips packaged into a pixel matrix, and then fixed to the plastic kit;
3. The indoor full-color display contains a driver chip and an input buffer chip, which can be connected to the LED display control system to display video, images and text information;
4. Through the system control of the driver chip driving red LED, green LED and blue LED, 4,398 billion color changes can be formed;
5 The unit board and the box can be spliced horizontally and vertically to form a display of different sizes;
6. Product features:
High quality lamp, high efficiency lamp brightness utilization rate, while ensuring the service life of the lamp and high-quality plastic parts
High contrast can achieve good display effect
The weight is easy to install and remove
Single point, single lamp maintenance, low cost
Constant current drive LED, uniform light, low power consumption
The driver chip uses SSOP package constant current driver chip
