characteristic
1. Choose DID control panel
Samsung's original DID (Digital Information Display) control panel technology has become the focus of attention in the display information industry chain. The subversive improvement of the DID control panel depends on the LED luminous tube degree, ultra-high contrast, ultra-durability and ultra-ultra-narrow application, which solves the technical obstacles of the liquid crystal display used in public display information and data outdoor advertising light boxes. Generally speaking, the chromaticity of LCD screens commonly used on TVs or computers is only 250300cd/m2, and the chromaticity of LCD screens with DID control panel can reach 700cd/m2, and the saturation can reach 10000:1, which is better than traditional ones. The LCD screen on the computer or TV is more than doubled, and it is three times the general rear projection. Therefore, the technical professional LCD display with the DID control panel is clearly visible even under direct sunlight.
2High brightness
Compared with TV and PC liquid crystal displays, LCD liquid crystal displays have higher chromaticity. The chromaticity of TV or PC liquid crystal display is generally only 250300cd/㎡, while the chromaticity of DIDLCD liquid crystal display can reach 700cd/㎡ (46"). 3. High-contrast DID liquid crystal display has 3000:1 ( 46 ") The saturation is more than twice that of traditional PC or TV LCD screens, and three times that of normal rear projection.
3 Image resolution technology
Allows low-resolution images to be reproduced clearly in the full HD display; to solve technical problems line by line, to eliminate flicker; to eliminate overlapping optimization algorithms, to eliminate "jaggies"; dynamic interpolation compensation, three-d comb filtering Detector, 10-bit data chromaticity and its color enhancement, automatic skin color calibration, three-d motion compensation, discrete system zoom and other international leading technical solutions.
4. Stronger colorful contrast
Generally, the color contrast of CRT is only about 50 percent , while DIDLCD can achieve high color contrast of 92 percent . This is due to the color correction technology developed and designed for product technology. According to this technology, except for the color development on the stationary interface In addition to the correction, the color correction of the dynamic interface can also be carried out, so as to ensure the accuracy and stability of the interface output.
5. A wider angle
PVA (Patterned Vertical Alignment) technology is the "image vertical adjustment technology", using this technology, the visibility angle of view reaches double 178 degree (horizontal and vertical).
More credibility
Generally, the LCD screen is a TV and PC display design, which is not compatible with day and night continuous applications. The LCD splicing wall is a monitoring system and exhibition center design solution, which is suitable for 7x24 continuous applications.
6. Pure floor plan display information
LCD is a flat-panel display device, which means it is a true flat-screen display, completely without a large interface with refractive index, and without deformation and frame loss.
7. Slim and ultra-narrow design
