What is the size of the LED display module?
The LED module is divided into two categories. The indoor led module is generally called table stickers (three -in -one table stickers); outdoor and semi -outdoor are generally called modules. The characteristics of indoor table stickers: high image clarity, color and richness, not enough for high prices; outdoor and semi -outdoor module unit board features: high brightness, waterproof, rich color.

The quality of LED lamp beads determines the color saturation and clarity of the performance of the entire LED display display. Therefore, the LED module's lamp beads are particularly important at the raw material selection and packaging process. It directly determines the quality and performance of the LED display module product product quality and performance.
2. Select according to the PCB board of the module
PCB boards with stable performance LED display modules are generally composed of substrates and metal coatings. Because there are many links in the quality of PC boards in the external environmental impact module during the application process
3. Select according to the suite of the module
The LED unit board module kit is one of the main causes of the display effect, and is the key element of the entire unit board and the entire stitching screen. The LED unit board kit must be able to prevent moisture, waterproof, and ultraviolet protection, and the quality of the kit will affect the flatness, contrast and service life of the display.
