Abstract: In recent years, LED displays have become more and more popular in the market due to their excellent brightness and color performance and their unbreakable picture integrity. However, some cities have also experienced problems due to the high brightness of LED displays that affect the lives of residents around them and traffic. How to adjust the brightness and color of the LED display, edit and share with you a few tips.
In recent years, LED displays have become more and more popular with the market due to their excellent brightness and color performance, as well as seamless screen integrity. However, some cities have also experienced problems due to the high brightness of LED displays that affect the lives of residents around them and traffic. How to adjust the brightness and color of the LED display, edit and share with you a few tips.
First, the brightness adjustment 1, the modulation pulse width (PWM), the use of human eyes can feel the frequency of change, the use of pulse width modulation method to achieve gray control, that is, periodically change the optical pulse width. Pulse width modulation is more suitable for digital control and has been widely used. The most common method is to adopt a microcomputer. At present, almost all LED displays adopt pulse width modulation to control the gray level.
2. Common LED tubes allow continuous task current to be around 20 mA. By changing the current flowing through the LED, the brightness of the rest of the LED is basically proportional to the current flowing in addition to the saturation of the red LED.
Second, the color adjustment LED high-definition display is installed on the principle of three primary colors display. The determination of the red, green, and blue colors is based on the brightness of the selected product's red, green, and blue colors. In general, the luminance reference is a type with a low luminance ratio. When the maximum brightness has been reached, it is necessary to adjust another color for the two-color LED display screen, and for the full-color LED display screen, the color of the other two kinds of LEDs is adjusted.
