The differences between LCD matrix screens and LED matrix screens

The differences between LCD liquid crystal display (LCD) mosaic screens and LED displays: Characteristics of LCD mosaic screens
1. High brightness and high contrast: DID liquid crystal mosaic screens have higher brightness compared to ordinary TV and PC liquid crystal screens. The brightness of TV or PC liquid crystal screens is generally only 250-300 cd/m2, while the brightness of DID liquid crystal screens can reach over 700 cd/m2. DID liquid crystal mosaic screens have a contrast ratio of 1200:1, even up to 10000:1, which is more than twice that of traditional PC or TV liquid crystal screens and is three times that of common projection screens.
2. Thanks to the professional color calibration technology developed for DID products, through this technology, not only can the color be calibrated for static images, but also for dynamic images. This ensures the accuracy and stability of the image output. In terms of color saturation, DID LCD can achieve a high color saturation of 80%-92%, while the color saturation of ordinary CRT is only about 50%.
3. Uniform brightness, stable image without flickering. Due to the fact that each point of LCD maintains the same color and brightness after receiving the signal, unlike CRT which requires continuous refreshing of pixel points. Therefore, LCD has uniform brightness, high picture quality and absolutely no flickering.
4. 120Hz double-frequency refresh rate, the 120Hz double-frequency liquid crystal display technology of DID products can effectively solve the trailing and blurring during the rapid movement of images, enhance the clarity and contrast of the image, and make the picture clearer. The human eye is less likely to feel fatigue when watching for a long time.
5. Broader viewing angle, by using this technology, the viewing angle can reach double 180° (horizontal and vertical), and through the application of PVA technology, also known as "image vertical adjustment technology", the LCD mosaic screen has a wider viewing angle.
6. Pure planar display, LCD is the representative of flat display devices, a true flat monitor, completely without curvature and large screen? without distortion and distortion.
7. Ultra-thin and narrow-edge design. LCD mosaic screens not only have the characteristic of a large display area, but also have advantages such as ultra-lightweight. They can be easily spliced and installed. The splicing-specific LCD screen, with its excellent narrow-edge design, ensures that the edge of a single piece is even below 1 cm, and this small edge effect will not affect the overall display effect of the entire screen.
8. Long service life, the backlight of DID LCD liquid crystal screens has a service life of over 5-100,000 hours? This ensures the consistency of brightness, contrast and color of each spliced LCD screen after long-term use? and ensures that the service life of the display screen is not less than 50,000 hours.
9. Better reliability, ordinary liquid crystal screens are not designed for continuous use day and night. DID liquid crystal screens are designed for monitoring centers and display centers? supporting continuous use 7x24 hours.
The differences between LCD liquid crystal display (LCD) mosaic screens and LED displays: Characteristics of LED displays
1. Strong light emission in the visible distance when sunlight shines directly on the screen surface, the displayed content is clearly visible.
2. Automatic brightness adjustment has an automatic brightness adjustment function, which can achieve the best playback effect in different brightness environments.
3. Various information display, network display, remote control
4. Advanced digital video processing, distributed scanning, modular design / constant current static drive, automatic brightness adjustment
5. Super gray level control with 1024-4096 levels of gray level control, displaying over 16.7M colors, clear and realistic colors, strong three-dimensionality
6. Static scanning technology adopts static latch scanning mode, high-power drive, fully ensuring the brightness
7. Fully adopt imported large-scale integrated circuits, reliability greatly improved, convenient for debugging and maintenance 8. The static scanning technology adopts a static latch scanning method, with high-power drive, ensuring sufficient light emission brightness.
9. The image is clear, without jitter or ghosting, and distortion is completely avoided.
