How to solve the LED display mosaic problem?
Full-color LED display “mosaic” phenomenon is a problem that has been plaguing LED display manufacturers. It is manifested in the form of display surface brightness subregion inconsistency, from the phenomenon, LED display “mosaic” phenomenon is manifested in the display surface bright homogeneity, i.e., poor uniformity. poor uniformity of the LED display screen, including poor brightness uniformity and poor chromaticity uniformity of the two aspects, poor uniformity, presenting the “blossom” or “mosaic” phenomenon will seriously affect the image viewing effect. “Mosaic” phenomenon will seriously affect the image viewing effect. The root cause of mosaic is the consistency of the lamp itself and the use of the consistency of defects caused.
First, what is the LED display mosaic phenomenon?
LED module is the LED (light-emitting diode) arranged in accordance with certain rules and then encapsulated, plus some waterproofing treatment of products, is the LED module. Said quadrilateral module can be with a decorative structure for blurring the boundaries of the module splicing on the main view. LED module COB light source LED surface light source utility model from the perspective of vision and optics, so that the straight line to form a dislocation of the short line strips, the use of visual rectilinearity, the human eye visual scanning from the top to the bottom (or left and right direction movement) can not be taken into account at the same time the dislocation of the two strips, it is bound to form countless dislocation of the discontinuous short line segment This completely eliminates the LED display mosaic phenomenon formed by the gap between the modules.
LED module is a LED product in the wider application of the product, in terms of structure and electronics there is also a big difference, simple is to use a circuit board equipped with LEDs and the shell into a LED module, complexity is added to some of the control, constant current source and the related heat dissipation processing to make the LED life and luminous intensity better.
Second, how to solve the LED display “mosaic” problem?
In the LED display manufacturers use the same batch of red, green and blue LED lights, and the batch of LED lights red, green and blue to re-grade. For constant current devices for inter-slice staging, a total of 5 gears, and each grade of constant current source evenly distributed to the whole screen for LED unit board production, with standard production fixtures to ensure that the LED lights in the same module are in the same balanced position.
Control the mold making process to ensure that all the LED lights in the module in the horizontal, up and down, front and back are no abnormal deviation. After filling the glue, use the standard front cover to fix the lights. Each LED unit board for single module brightness adjustment, that is, white balance fine-tuning, to ensure uniform white balance between modules.
Assemble the modules into a box. The box body adopts steel plate ribbed structure with strong reinforcement at appropriate positions. Ensure the steel and flatness of the box plane. Box stamping, bending using CNC equipment for one-time molding, the use of CNC punching machine to ensure that the module is installed in place precision. And there is an appropriate margin to eliminate the cumulative error.
