Different degrees of subregional "Mosaic" phenomenon has long been a problem in LED display manufacturers. Look from the phenomenon, LED display the phenomenon of "Mosaic" light to show the display surface, namely uniformity is poor. Due to the fundamental cause of Mosaic is the consistency of the lamp itself from defects and consistency when using.
What is the LED display Mosaic phenomenon?
LED module is to turn the LED (light-emitting diode) arranged according to certain rules to encapsulate together, plus some waterproof treatment of products, is the LED module. Described the quadrilateral module's main visual surface could be used for fuzzy module with the adornment of the stitching line structure. Module COB LED light source LED light face utility model from the perspective of visual and optical, make form the dislocation short straight line, the use of visual linearity, the human eye vision from the top down (or direction) scan can't both dislocation, dislocation is bound to form numerous discontinuous short line segment, so as to eliminate the gap between the due to the module of LED display Mosaic phenomenon.

LED module is LED products are widely used in products, in terms of structure and electronic there are great

 differences, simple is to use an LED circuit board and the shell became an LED module, complex could add some control, constant current source and relevant heat treatment to make LED luminous intensity and better life.

How to solve the problem of "Mosaic"?
On every piece of LED display manufacturers use the same batch of red, green and blue leds, and the number of leds are red, green, blue for second step. Constant current devices for step between slices, which is divided into five files, and the constant current source uniform distribution of each class to the whole screen LED unit board production, using standard production jig ensure LED lights are in the same module in the same equilibrium position.
Control of mould making process, to ensure that all the leds of the module in a horizontal, up and down, and no abnormal offset. After the glue, using standard front cover will light fixed. Every single module LED unit board of brightness adjustment, namely white balance tweaks, ensure uniform white balance between modules.
The module assembly into housing. Enclosure structure of steel reinforcement, and in the appropriate position with strong gluten. Ensure the smoothness and rigidity in the plane of the body. Body stamping, bending adopt numerical control equipment, a forming adopts CNC punch press ensure accuracy of modules installed. And has the appropriate allowance to eliminate the accumulated error.
