Terminology of LED injection molding module

Time:2017/07/26    Article Release:本站

In understanding the LED injection molding module, we must solve some problems, which are related to the professional terms of the LED injection molding module, such as resolution, LED brightness, dot pitch, grayscale, dual primary color, full color. Let's find out together.


1. Resolution


The number of rows and columns of LED display pixels is called the resolution of LED display. Resolution is the total number of pixels in the display, which determines the information capacity of a display.


2. Brightness of LED injection molding module


Under normal circumstances, the brightness of the indoor LED injection molding module display is different from the brightness of the outdoor LED injection molding module display. The light intensity of the group display is 100mcd-1000mcd, or even above 1000mcd.


3. Dot pitch, pixel density and information capacity


The dot pitch refers to the center distance between two pixels of the LED injection molding module display screen. The number of pixels in a unit area is called pixel density, and the number of display contents contained in a unit area is called information capacity. Dot pitch, pixel density, and information capacity are the same concepts described, that is, dot pitch reflects the pixel density from the distance between two pixels, dot pitch and pixel density are the physical properties of the display screen, and information capacity is the information of pixel density. Quantitative unit of carrying capacity. The smaller the dot pitch, the higher the pixel density, the more information capacity, and the closer the viewing distance is. The larger the dot pitch, the lower the pixel density, the less information capacity, and the longer the distance suitable for viewing.


4. Grayscale


Grayscale refers to the brightness of the pixel's light emission. The grayscale of a primary color generally ranges from 8 to 1024 levels. Under normal circumstances, the grayscale of the LED injection molding module display is 256 levels.


5. LED injection molding module pixel module


LED injection molding modules are arranged in a matrix or pen segment, prefabricated into standard size modules. The pixel module for outdoor display screens is also called a manifold module because each pixel is composed of more than two LED injection molding module tube bundles.


6. Double primary color


Double-click color LED injection molding module display, that is, each pixel has two LED injection molding module dies, red and green dies, when the red die is on, the pixel is red, and when the green die is on, the pixel is red. The pixel is green, and when the red and green dies are on at the same time, the pixel is yellow.


7. Full color


Red and green two primary colors plus blue primary colors, three primary colors constitute a full color. Since the technology for forming full-color blue tubes and pure green dies is now mature, full-color is basically used in the market.
