Analysis of seven common technical terms of LED display
Sensor Basin Faucets can make your bathroom cleaner and easier to use. Since you don`t need to touch a handle or knob, you can turn the water on with something in your hand, and you won`t spread germs or bacteria to the other people in your household. If you`re remodeling the bathroom, consider these benefits of hands-free faucets.

1. LED brightness: The brightness of a light emitting diode is generally expressed in terms of luminous intensity (Luminous Intensity), and the unit is Candela cd; 1000 ucd (micro candela)=1 mcd (m Candela), 1000 mcd=1 cd. The light intensity of a single LED for indoor use is generally 500 ucd-50 mcd, while the light intensity of a single LED for outdoor use should generally be 100 mcd-1000 mcd or even over 1000 mcd.
2, LED pixel module: LED arrayed into a matrix or a pen segment, pre-made into a standard size module. Indoor display commonly used 8 * 8 pixel module, 8 word 7 segment digital module. Outdoor display pixel modules have 4*4, 8*8, 8*16 pixels and other specifications. Pixel modules used in outdoor displays, because each pixel consists of more than two LED tube bundles, is also referred to as a manifold bundle module.
3. Pixel and Pixel Diameter: Each LED light unit (point) in the LED display that can be controlled individually is called a pixel (or pixel). The pixel diameter ∮ refers to the diameter of each pixel in millimeters.
4. Resolution: The number of rows of LED display pixels is called the resolution of the LED display. Resolution is the total number of pixels in the display, which determines the information capacity of a display.
5. Grayscale: Grayscale refers to the degree of light and shade changes of a pixel's light, and a basic color has 8 to 12 levels of gray. For example, if the gray level of each primary color is 256, for a dual-color color screen, the display color is 256*256=64K, which is also known as a 256-color display.
6, dual-color: that each pixel has two LED dies: a red light core, a green light core. The pixel is red when the red light is on, green when the green light is on, and yellow when both red and green are on. Among them, red and green are called base colors.
7, full color: red and green double color plus blue base color, the three primary colors constitute full color. Since the technology for forming full-color blue tubes and pure green dies is now mature, the market basically uses full-color. [Editor: ltongled]
