Factors affecting the quality of full-color LED display_Shenzhen full-color LED display manufacturer

Nowadays, the demand for LED displays in our lives is increasing, and the scope of applications is getting wider and wider. Then, how should we judge the quality of an LED display? The relevant staff of Huaze Optoelectronics will be coming soon. Answer for everyone. 1. The problem of the mask kit The ink color and consistency of the mask directly affect the display effect of the LED display. If the ink color is good, the quality of the LED lamp is good, and basically there is no big problem in the display. 2. White balance effect The white balance effect is one of the most important indicators of the display. In color science, pure white will be displayed when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16. If the actual ratio is a little different, the white balance will be deviated. Generally, pay attention to whether the white is blue or yellow. Green phenomenon. The quality of the white balance is mainly determined by the control system of the led display, and the die also has an impact on the color reproduction. 3. The waterproof treatment of the outdoor led display depends on whether it is machine glue or manual glue, the quality of the glue, and the ratio of glue are related. 4. Color reproducibility Color reproducibility refers to the color reducibility of the display screen, that is, the color displayed on the led display must be highly consistent with the color of the playback source, so as to ensure the realism of the image. 5. The thickness of the iron sheet of the box body and the regularity of the box body are related to the structure drawings of the box body made by the LED display manufacturer. The structure is completed, the installation is convenient, and other heat dissipation will be better. 6. Whether there is mosaic or dead spots. Mosaic refers to the small four squares that are always bright or black that appear on the LED display. It is the phenomenon of module necrosis. The main reason is that the quality of the connectors used in the display is not good enough. Dead point refers to a single point that is always bright or black that appears on the LED display. The number of dead points is mainly determined by the quality of the die. 7. Whether there is color block Color block refers to the obvious color difference between adjacent LED display modules. The color transition is based on the module. The color block phenomenon is mainly caused by the poor control system and the gray level. High, caused by low scanning frequency. 8. There are many circuit board manufacturers. Shenzhen is a gathering place for electronic products. The purchase of raw materials is very fast. The circuit boards are divided into two-layer and four-layer boards. What affects the quality of the circuit board is the conductor inside the circuit board. , The thickness of the conductor should reach the standard thickness of 1ns or more, because the temperature of the led display screen increases and decreases during use. If the conductor is thin, it will easily fuse during use, which will result in a large area of u200bu200bquality. problem. 9. Brightness and viewing angle The brightness of the indoor full-color led display must be above 800cd/m², and the brightness of the outdoor full-color led display must be above 1500 cd/m² to ensure the normal operation of the led display. The brightness is too low to see the displayed image clearly. The size of the brightness is mainly determined by the quality of the LED die. Of course, it is not that the brighter the brightness, the better, because increasing the current can increase the brightness of the LED lamp, but this will affect the life of the LED lamp. The next bad LED display business opportunity is to start to increase the LED brightness to make you look good , But generally can’t be used in less than a year. The size of the viewing angle directly determines the audience of the display screen, so the larger the better. The size of the viewing angle is mainly determined by the packaging method of the die. So the most important thing is to look at the uniformity of the brightness. Uniformity means that the brightness is almost soft, and you can change the angle to see under the light. The evaluation of uneven brightness looks like a very dirty feeling. It's like I didn't wipe it clean. 10. Flatness The flatness of the surface of the full-color LED display should be within ±1mm to ensure that the displayed image is not distorted. Local protrusions or recesses will cause a blind spot in the viewing angle of the display. The quality of flatness is mainly determined by the production process. The above are the 10 factors that determine the quality of the full-color LED display.
