Shenzhen Fengyingxin Optoelectronics Co., Ltd. was established on October 1, 2001. Since its establishment, the company has been focusing on the research and development of LED, LED bottom-side backlight and other optoelectronic devices. Products are widely used in audio, communications, multimedia, electronic appliances, toys, household appliances and instrument lights. Is a domestic manufacturer of LED backlight, LCD backlight, logo backlight and other backlight manufacturers.
The LED screen is definitely not a common LED backlight, and the LED display is also called an electronic display or floating characters. By LED dot matrix and LEDPC panel, text, image, animation, video and content can be displayed by the red, blue, white and green LEDs on and off. According to different occasions and different supervisions, such as general billboards and the flowing calligraphy, it is produced by flash animation needs, saved in the display of the memory card, and then displayed by technical methods. It can be changed at any time according to different needs. The various parts are in the modular structure of the display device. The traditional LED display screen usually consists of display module, control system and power supply system.
The color and luminous efficiency of the LED light are all blue at the beginning of the production material and the related LED light bulb process, but later together with the phosphor, different light colors are adjusted according to the different needs of users, the widely used red, green, and blue, Yellow 4. Due to the low working voltage of the LED, it can actively emit light and has certain brightness, brightness and voltage adjustment. It is also resistant to shock, vibration and long life (100,000 hours), so in large display equipment, there are no other display methods and LEDs. The display matches.
Red and green LED chips or lights are made together as pixels to display the so-called black and white or monochromatic screen and three-color or two-color screen. Red, green and blue LED chips or discharge lamps are made together as a pixel display called a three-color screen or Full color screen. If there is only one color, the indoor LED screen is called a monochrome pixel size, which is generally 2-16 mm. It is often used to make a variety of different colors of LED dies into a package. The pixel size of an outdoor LED large screen is mainly 6 mm-31.5, each pixel consists of several various monochromatic LEDs, which means pixel tubes, two-color pixel tubes are generally composed of two red, 1 green, three-color pixel tubes, red, green, and blue. 1 common product.

LED screen people's lives and closer cooperation
Whether to produce a single-color, two-color or three-color screen with LEDs, the image needs to be displayed by adjusting the brightness of each LED that constitutes the pixel. The higher the level, the more delicate the grayscale image display, the richer the color, and the more complicated display control system. Generally, 256-level grayscale images have very soft color transitions, while 16-level grayscale color images have very obvious color transition boundaries. Therefore, the demand for color LED displays is doing 256-4096 gray.
Through extensive attention and rapid development of LED, 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 displays have the characteristics of environmental protection, high brightness, high definition, and high reliability. On the stage, the market of LED displays just meets the needs of people, but for LED display products, they do not meet the requirements. low quality. With the development of LED displays, LED products now have a new breakthrough. At least compared with the previous stage, improve progress. In addition, we have developed a series of completely different products that are applied from traditional light sources will become popular. LED display screens will have greater development and broader space. The LED display is not only beautifying, it has changed the way people work more closely and make life more closely.
