50 inch Panel Module

Regardless of whether a single-color, two-color or three-color screen is made with LEDs, the brightness of each LED that is required to form an image must be adjustable, and the degree of fineness of the adjustment is the gray level of the display. The higher the gray level, the finer the displayed image and the richer the color, and the more complex the corresponding display control system. Generally, the image of 256 gray scales has a very soft color transition, while the color image of 16 gray scales has a clear color transition boundary. Therefore, color LED screens are currently required to be 256 to 4096 grayscale.

 

The LED luminescent materials used in the display screen have the following forms:

1 LED light (or single light) Generally consists of a single LED chip, reflective bowl, metal anode, metal cathode, and an epoxy resin shell with light-transmitting ability. One or more (different color) single lamps can be used to form a basic pixel, which is mostly used for outdoor displays due to high brightness.

2 LED dot matrix module The light matrix is composed of several wafers and encapsulated in a plastic case with epoxy resin. It is suitable for row and column scanning drive, and it is easy to form a high-density display screen, which is mostly used in indoor display.

3 SMD LED lighting (or SMD LED) is the package of LED lighting, which can be used in indoor full color display, which can realize single point maintenance and effectively overcome the mosaic phenomenon.
