LED display screens are increasingly favored by the market due to their excellent brightness and color performance, as well as seamless picture integrity. However, in some cities, problems such as high brightness of LED display screens have affected the lives of surrounding residents and traffic. How to adjust the brightness and color of the LED display, here, Winbond Editor will share with you a few tips.

LED display screens are widely used in various industries, and different applications have different requirements for the wavelength of the primary color of the LED. Some of the wavelengths of the primary color of the LED are selected to achieve good visual effects, and some are to meet people's requirements. Customs, and some are more regulated by industry standards, national standards and even international standards. For example, the choice of the wavelength of the primary color of the green tube in a full-color LED display; in the early days, people generally used a yellow-green LED with a wavelength of 570nm. Although the cost is low, the color gamut of the display is small, the color reproduction is poor, and the brightness is low. After choosing a pure green tube with a wavelength of 525nm, the color gamut of the display screen has nearly doubled, and the color reproduction has been greatly improved, which greatly improves the visual effect of the display screen. Another example is the stock market display screen. People are usually accustomed to using red to indicate stock price increases, green to indicate stock prices falling, and $ to indicate flat prices. In the transportation industry, the national standards strictly stipulate that the blue and green bands are for traffic and the red band is forbidden. Therefore, the choice of the wavelength of the primary color is one of the important aspects of the LED display.
