LCD Splicing Screen and Video Matrix

The display unit adopts LCD technology with high definition, high brightness and high color gamut, capable of displaying up to 16.7 million colors with a wide viewing angle and a lifespan of 50,000 hours, meeting 24/7 operation requirements. The spliced video wall is ultra-light, ultra-thin, long-lasting, low-maintenance, low-power, radiation-free and high-definition.
1.1LCD Display Principle and Structure

1. Formation of the LCD Display Panel
   The LCD display is relatively complex, with its main components including fluorescent tubes, light guide plates, polarizers, color filters, glass substrates, alignment layers, liquid crystal materials, thin-film transistors, etc.
2. Working Principle of the LCD Display
   First, the LCD display must utilize a backlight source, i.e., fluorescent tubes projecting light. This light first passes through a polarizer and then through the liquid crystal, where the arrangement of liquid crystal molecules changes the angle of light passing through the crystal. The light then passes through a front color filter film and another polarizer. Therefore, by changing the voltage applied to the liquid crystal, we can control the final light intensity and color, thereby producing different shades and color combinations on the LCD panel.
3. LCD Display Characteristics
   a) High Resolution
   LCD offers higher resolution. LCD displays computer signals at XGA, SVGA, VGA resolutions, and can also display DTV or high-definition HDTV signals.
   b) Flicker-free Picture
   Each pixel of the LCD is independently controlled and equipped with double-scan circuitry, so even ordinary TV signals or VCR tapes can present fine and perfect images.
   c) Accurate Color Reproduction
   Samsung LCD displays typically show up to 16.7M+ colors, providing a perfect 13-bit grayscale, supplemented by rich grayscale levels, delivering fuller and more vivid colors.
   d) Widescreen Display Mode
   The large-screen LCD display has a 16:9 aspect ratio instead of the traditional 4:3, designed for users to enjoy most DVD discs and future HDTV signals (16:9 aspect ratio). Of course, you can also select 4:3 format to watch regular TV program signals.
   e) Perfect Flat Panel Display
   LCD is a true flat panel display. The large picture has no curvature, with no deformation or distortion even at the corners.
   f) Uniform Brightness
   Most other mainstream display technologies suffer from uneven screen brightness (such as projection, PDP, CRT, etc.), but due to the unique display principle of LCD, brightness is very uniform, with no darkening at the corners.
   g) Ultra-thin Chassis Design
   While possessing a large display area, the LCD has an ultra-thin chassis, making it easy to install in any location. The ultra-light and ultra-thin advantages make LCD displays the best equipment for indoor large-screen display.
   h) Ultra-wide Viewing Angle
   Due to the light-emitting characteristics of the LCD light source, the viewing angle of LCD is extremely wide, exceeding 178 degrees in both horizontal and vertical directions.
   i) Full-system Signal Reception
   The LCD display can connect to most common video signal sources, including composite video S-Video (NTSC/PAL), standard AV signals (Video), DVD/HD (YPbPr), VGA signals output by computers, RGB/HV signals, and DVI signals.
