The 'mosaic' phenomenon has been a problem that has always plagued LED display manufacturers. From the perspective of phenomenon, the 'mosaic' phenomenon of LED display shows the inconsistency of the brightness of the display surface in different regions, that is, the poor uniformity. The root cause of the mosaic is caused by the consistency of the lamp itself and the consistency defects during use.
What is LED display mosaic phenomenon?
The LED module is a product made up of LEDs (LED Light module emitting diodes) arranged together according to a certain rule and then packaged together with some waterproof treatments, which is the LED module. The main viewing surface of the quadrilateral module can be provided with a decorative structure for blurring the splicing boundaries of the modules. LED module COB LED Light module source LED surface LED Light module source This utility model allows straight lines to form short staggered lines from the perspective of vision and optics. By using the linearity of vision, human vision cannot simultaneously take into account misalignment when scanning from top to bottom (or left and right). Two, it is bound to form countless dislocation discontinuous short line segments, which completely eliminates the LED display mosaic phenomenon caused by the gap between the modules.
LED module is a widely used product in LED products. There are also big differences in structure and electronics. The simple thing is to use a circuit board and housing equipped with LEDs to become an LED module. It is complicated Just add some control to the constant current source and related heat dissipation treatment to make the LED life and luminous intensity better.
How to solve the 'mosaic' problem?
Use the same batch of red, green, and blue LED lights on each LED display manufacturer, and reclassify the red, green, and blue colors of this batch of LED lights. For constant current devices, the chip is divided into 5 levels, and the constant current source of each level is evenly distributed to the entire screen for LED unit board production. Standard production fixtures are used to ensure that the LED lights are in the same module. The same equilibrium position.
Control the mold making process to ensure that all the LED lights in the module are level, up and down, front and rear without abnormal position. After filling the glue, use the standard front cover to fix the lamp. Each LED unit board performs single-module brightness adjustment, that is, white balance fine-tuning, to ensure uniform white balance between modules.
Assemble the module into a box. The box body adopts steel plate reinforcement structure, and strengthened ribs are added at appropriate positions. Ensure the rigidity and flatness of the box plane. The punching and bending of the box body are formed by numerical control equipment at one time, and the numerical control punching machine is used to ensure the accuracy of module installation. And there is a proper margin to eliminate the accumulated error.
are an important part of the society and they come in handy in any place where there are led light engine module in need of led light engine.
