High brightness, high color rendering, and seamless mosaic of pictures are the most important factors for LED display. However, in some occasions, because the brightness of the led display is too high, it brings trouble to the surrounding life. To solve this problem, here are a few tips to solve:
1, brightness adjustment:
Brightness adjustment can make the human eye feel the frequency of change by modulating the pulse width. The most common method of Led display is to adopt the microcomputer. In addition, the passing current of the led display can also be changed.
2, color adjustment:
The Led display product determines a color as a reference according to the brightness of the red, green and blue. In general, when the brightness of the reference reaches the highest brightness, the full color led display needs to adjust the other two colors.
- Select the appropriate primary wavelength:
Led display screens are used in a wide range of applications. For different occasions, the LED base color wavelength also has different requirements. For example, to meet people’s viewing habits, in line with industry, national standards, etc., so choose a good primary color wavelength is also very critical for LED display.
4, the allocation of white field color coordinates:
White field color coordinate modulation is one of the most basic technologies for full color LED display. With the promulgation of the industry standards and the improvement of equipment, LED display manufacturers have begun to standardize the color matching of full-color screens. However, due to the lack of theoretical guidance at this stage, the performance of this aspect is still not well improved.
