Indoor LED displays have become increasingly common in recent years, appearing in places such as hotels, train stations, and large supermarkets. So, what are the characteristics of LED displays?
I. Characteristics of Indoor LED Displays:
1. High Brightness: Outdoor LED displays have a brightness greater than 8000 mcd/㎡, making them the only large display terminal that can be used outdoors all day long; indoor LED displays have a brightness greater than 2000 mcd/㎡.
2. Long Lifespan: LEDs have a lifespan of over 100,000 hours (ten years). This parameter generally refers to the design lifespan, and includes the period even when the brightness decreases;
3. Wide Viewing Angle: The indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light-emitting diode. 4. The screen area can be large or small, ranging from less than one square meter to hundreds or even thousands of square meters;
II. Indoor Full-Color LED Display Functions
1. Video Playback Function:
Plays video programs from VCRs, DVD players (VCD, DVD, LD), etc., meeting the basic needs of cultural and sports activities;
Displays video images from cameras clearly and without flickering, enabling live broadcasting of various programs;
Brightness, contrast, saturation, and hue can be adjusted via software, with an adjustment range of 256 levels;
Uses the Line-Double function to convert interlaced images to non-interlaced images and perform motion compensation;
Can play various file formats such as AVI, MOV, MPG, DAT, and VOB;
Has video image compression control function;
Has three display modes: overlay (VGA+VIDEO), video, and VGA;
Has display synchronization function;
Provides one audio signal output to the power amplifier and has at least two camera video input interfaces;
2. Information Release Function:
The full-color LED display can display various computer information, graphics, pictures, and 2D and 3D animations, with rich playback methods, displaying scrolling information, notices, slogans, etc., and has a large data storage capacity;
The broadcasting system has multimedia software, which can flexibly input and broadcast various information; it can play text information, and the playback format can be scrolling dots, scrolling lines, entry and exit modes, upward movement, leftward movement, and messages can be broadcast in a loop. Fonts and font sizes can be freely selected, and playback speed can be set. Multiple messages can be broadcast simultaneously, or simultaneously with animations and images.
The full-color LED display has a variety of Chinese fonts and styles to choose from, and can also input many foreign languages such as English, French, German, Greek, Russian, and Japanese;
3. Network Function:
The indoor full-color LED display is equipped with a network interface and can be networked with a computer. It can simultaneously broadcast network information and achieve network control. According to customer requirements, multiple screens in different locations can be centrally controlled through the network using "VPM + broadband" for remote control.
