- The first method is to change the current flowing through the LED. In addition to the saturation phenomenon of the red LED, the general LED tube allows a continuous current of about 20 mA, and the brightness of the LED is almost proportional to the current flowing. However, this method of changing the current flowing through the LED is relatively simple, but it is less and less suitable for rapid and precise modulation, and more accepts the following modulation method. The second is pulse width modulation, referred to as PWM. Its principle is: using the frequency of change of the eye to be perceived, the gray level control is completed by the pulse width modulation method, that is, the duty ratio, that is, the optical pulse width is periodically changed, and only the refresh frequency is sufficiently high, that is, such repetition The period of lighting is relatively short, and the eyes do not feel the jitter of the pixels. Because this method is more suitable for digital control, it has been widely used. More common is to adopt a microcomputer to provide LED display. Alm...

- The display display effect adjustment is divided into two parts, one is the resolution and the color, which is soft adjustment, adjusted in the WINDOWS system (right click "Desktop" - Properties - Settings); the other part is the adjustment of light and dark, screen size, etc. Adjustment, generally the corresponding adjustment button will be displayed below the display, you can press "MENU" to call up the corresponding menu and make the corresponding selection to adjust. If you still recover after this adjustment, it can only indicate that your monitor has a hardware failure and you have to repair it....

- LED subtitle modification software] Modify LED subtitle display method: Usually when we buy, the manufacturer will give us the corresponding LED subtitle modification software. Because each manufacturer writes different ways and habits, the software for each company‘s LED subtitles is different. Of course, some companies may adopt a unified programming specification, so they can be controlled using unified subtitle modification software. If you want to change the subtitles to what we want, we need to install the LED subtitle software on the computer first. After the installation, the next step is to connect with the corresponding LED electronic display. Most of them are connected by the number or serial number....
