led
Abbreviation for Light Emitting Diode. Widely seen in daily life, such as the indicator light of household appliances, fog lights behind the car. The most prominent feature of the LED is its long life and high photoelectric conversion efficiency.
The LED module LEDs are arranged in a matrix or a pen segment and are prefabricated into standard size modules. Commonly used 8X8 dot matrix module (64×1 for single color or 64×2 for dual color diodes), 8 word 7-segment digital module.
In order to increase the brightness and increase the line-of-sight, the LED tube assembly integrates two or more LEDs into a cluster tube as a pixel. This LED tube assembly is mainly used for making outdoor screens. Also known as a pixel tube.
LED display screen will be assembled according to the actual needs of the size of the LED module or assembly tube matrix, with a dedicated display circuit, DC power supply, software, frame and exterior decoration, which constitutes a LED display.
Pixel and pixel diameter
Each light-emitting unit in the LED display that can be individually controlled is called a pixel. Pixel diameter ∮ refers to the diameter of each LED light-emitting pixel, in millimeters. For indoor screens, the more common ones are ∮3, ∮3.7, ∮5, ∮8. ∮10 and so on, of which the most ∮5. For outdoor screens, there are ∮10, ∮12, ∮16, ∮18, ∮21, ∮26, ∮48, etc. (the units are in mm). There are usually more than one LED in an outdoor screen pixel.
The distance between the two pixels of the dot pitch LED display is called the dot pitch. The denser the dot pitch, the higher the pixel density per unit area, the higher the resolution, and the higher the cost. The smaller the pixel diameter, the smaller the dot pitch.
The number of rows and columns of pixels in the resolution LED display is called the resolution of the LED display.
Gray-scale gray-scale refers to the degree of light-to-dark change of pixels. A gray color of a basic color generally has 8 levels to 256 levels. For example, if the gray level of each primary color is 16, for a dual-color color screen, the display color is 16*16=256 colors, also known as the screen is a 256-color display screen.
Dual Colors Most color LED displays today are dual-color color screens, ie, each pixel has two LED dies: one for the red die and one for the green die. 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 the basic colors.
The full-color red-green dual-primary color plus the blue-based color, the three basic colors constitute a full-color. Due to the expensiveness of the blue die, there are currently relatively few full-color screens.
