LED display and LCD splicing screen characteristics analysis

• LED display Features

1. Strong luminous brightness in the visible distance in direct sunlight on the screen surface, the display content is clearly visible
2. Automatic brightness adjustment with automatic brightness adjustment function, can get the best playback effect in different brightness environment.
3. Video, animation, charts, text, pictures and other information display, network display, remote control
4. Advanced digital video processing, technology distributed scanning, modular design/constant-current static drive, automatic brightness adjustment
5. Super grayscale control with 1024-4096 levels of grayscale control, display color 16.7M or more, clear and realistic colors, strong sense of three-dimensionality
6. Static scanning technology adopts static latch scanning mode, high power drive, fully guarantee the luminous brightness.
7. Comprehensive use of imported large-scale integrated circuits, greatly improving reliability, easy to debug and maintain
8. Static scanning technology adopts static latch scanning mode, high power drive, fully guarantee the brightness of light emission.
9. The image is clear, no jitter and ghosting, and eliminate distortion.
10. Ultra-high brightness pure color pixels
11. All-weather work fully adapted to a variety of harsh outdoor environments, waterproof, moisture-proof, anti-corrosion, lightning, seismic overall performance, display performance, cost-effective, pixel tube can be used P10mm, P16mm and other specifications.

• LCD splicing screen Features

1.high brightness, high contrast ratio: DID LCD splicing screen has a higher brightness, different from ordinary TV and PC LCD screen TV or PC LCD screen brightness is generally only 250~300cd/m2, while the brightness of DID LCD screen can reach more than 700cd/m2. DID LCD splicing screen has a contrast ratio of 1200:1, or even up to DID LCD splicing screen has 1200:1 contrast ratio, and even up to 10000:1 contrast ratio, than the traditional PC or TV LCD screen to be more than twice as high as the general rear projection of three times.
2. Thanks to the DID products for the professional development of color calibration technology, through this technology, in addition to color calibration of the static picture can also be color calibration of the dynamic picture. This ensures accurate and stable picture output. In terms of color saturation, DIDLCD can reach 80% -92% high color saturation, while the current ordinary CRT color saturation is only about 50%.
3. Uniform brightness, image stability without flickering. As the LCD each point in the received signal has been to maintain the color and brightness, unlike CRT as the need to constantly refresh the pixel points. Therefore, LCD brightness uniformity, high picture quality and absolutely no flicker.
4.120HZ times the refresh frequency, DID products 120Hz times the frequency of LCD technology can effectively solve the image of rapid movement in the process of tailing and blurring to enhance the clarity of the image and contrast to make the picture clearer  human eyes are not easy to fatigue for long periods of time to watch.
5. Wider viewing angle, the use of this technology viewing angle of up to double 180 ° (horizontal and vertical), through the PVA technology that is “image vertical adjustment technology” application makes the LCD splicing screen has a wider viewing angle.
6. Pure flat display, LCD is a representative of the flat panel display device, is a true flat display, completely curvature-free big picture distortion-free distortion.
7. Ultra-thin narrow edge design, LCD splicing screen not only has the characteristics of large display area, there are advantages such as ultra-thin. Can be easily spliced and installed. Splicing special LCD screen, its excellent narrow edge design, so that the edge of its single piece even below 1 centimeter, so that the small edge effect will not affect the overall display effect of the whole display.
