How to distinguish between LED display and LED backlight
Jul 17, 2018
LED screens are definitely not a common LED backlight, and LED displays are also known as electronic displays or floating words. The LED dot matrix and the LEDPC panel display text, images, animations, videos, and content through the red, blue, white, and green LEDs. According to different occasions, different regulations, such as general billboards, these flowing calligraphy, are carried out by the requirements of flash animation production, saved in the display of the memory card, and then displayed by technical methods, which are changed according to different needs. Each part is a modular structure of the display device. Traditional LED displays are typically made up of display modules, control systems and power supply systems.
LED illuminates the color and luminous efficiency and produces all the blue color of the material and related LED bulb process, but later with the phosphor, adjust the different light colors according to the different needs of users, widely used red, green, blue, Yellow 4. Due to the low operating voltage of LED, it can actively emit light and have certain brightness, brightness and voltage regulation, and it is resistant to shock, vibration and long life (100,000 hours). Therefore, in large display devices, there is no other display mode and LED. The display matches.
Red and green LED chips or lights are made together as pixels, showing so-called black and white or monochrome screens and three- or two-color screens, red, green and blue LED chips or discharge lamps together as a pixel display called tri-color screen or Full color screen. If only one color is called a monochrome pixel size, the indoor LED screen is typically 2-16 mm, which is often used to make a variety of different color LED dies to a package. The outdoor LED large screen pixel size is mainly 6mm - 31.5, each pixel consists of several kinds of monochromatic LEDs, which is said to be a pixel tube, a two-color pixel tube is generally composed of two red, green, and three-color pixel tubes, red, green, and blue.

LED screen people's lives and closer cooperation
Whether the LED produces a monochrome, two-color or three-color screen, the image needs to be displayed for each LED illuminating brightness of the pixel that must be able to adjust the adjusted gray level. The higher the level, the more grayscale the image is displayed, the more colorful it is, and the corresponding display control system is more complicated. Generally, the image of 256-level gray scale has a very soft color transition, while the color image of 16-level gray scale has a clear color transition boundary. Therefore, the demand for color LED displays is doing 256-4096 gray.
Through extensive attention and rapid development of LEDs, this is inseparable from its own advantages. The extremely broad development prospects of LED are moving towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, and full colorization.
LED display has the characteristics of environmental protection, high brightness, high definition, high reliability, and on the stage, the market of LED display just meets people's needs, but for LED display products, but does not meet the requirements, low quality. With the development of LED displays, LED products now have a new breakthrough. At least than the previous stage, improve progress. In addition, we have developed a series of completely different products that will be popular from traditional light source applications. LED displays will show greater development and broader space. The LED display not only beautifies the role, it changes the way people work more closely to make life more and more.
