Silly not clear LED screen is not commonly used LED backlight

LED display also known as electronic display or floating word screen. Is composed of LED dot matrix and LED PC panel, through the red, blue, white, green LED lights out to display text, pictures, animation, video, content. Can make different adjustment according to the needs of different occasions, such as billboards that flow and is produced by flash an animation, savings in a memory card display, through the display techniques, can change according to different needs, each part of the components are display module the structure of the. Traditional LED display is usually composed of display module, control system and power system.

Light color and luminous efficiency of LED and production of LED material and technology, the beginning is full of blue light ball, but followed by fluorescent powder, according to the different needs of customers, adjust the different color, widely used are red, green, blue and yellow four. Because the LED low voltage, active luminescence and a certain brightness, brightness and voltage regulation, and impact resistance, vibration resistance, long life (100 thousand hours), so in a large display device, there is no other display and LED display mode.

LED display (three color screen or full color)

The red and green light LED chip or put together as a pixel made display called the single color or monochrome screen and color or double color screen, the red, green and blue three LED chip or lamp put together as a pixel display screen called three color or full color. If there is only one kind of color is called color, make indoor LED screen pixel size is generally 2-16 mm, often used to produce several different primary colors LED die package into a whole, outdoor LED screen pixel size is 6-31.5 mm, each pixel comprises a plurality of monochromatic LED, common product called pixel tube double color pixel tube, usually consists of 2 Red 1 green, 1 Red 1 green 1 blue three color pixel tube.

LED screen more appropriate people work and life

Regardless of the use of LED monochrome, two-color or three color screen, to display the image needs to constitute a pixel of each LED luminous brightness must be able to adjust, the degree of adjustment is the display of the gray level. The higher the gray level, the more delicate the image is, the richer the color is, the more complex the display control system is. General 256 gray level image, color transition has been very soft, and the color of the gray level of the 16 levels, color transition boundaries is very obvious. Therefore, the color LED screen is currently required to make 256 to 4096 gray.

LED display

LED has been widely valued and developed rapidly, which is inseparable from its own advantages. The development prospect of LED is very broad, and it is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and full color.

Back of LED screen

LED display with environmental protection, high brightness, high resolution, high reliability and other characteristics gradually emerged, but on a stage, the LED display market is to meet the demand of people, but in the LED display products are not up to the requirements, but the quality of. With the development of LED display, and now LED products have a new breakthrough. At least improve progress over the previous stage. Also developed a series of products that are completely different from the traditional light source will be popular. LED display will be bigger and broader space for development. LED display is not only the role of landscaping, it makes the more appropriate changes in people's lives and work bit by bit.
