Technology 1: How to automatically switch on and off the LED display First, the BIOS settings are automatically turned on every day. Step 1: Start the LED display servo computer, press DEL, enter the BIOS, and then select “POWER MANAGEMENT FEATURES†"Enter, enter. In the power window, find the "RESTORE ON AC / POWER LOSS" item, press Enter, and then set its value to "POWER ON" by the arrow keys; Step 2: Select “RESUME ONRTC ALARM†and press Enter, then set the value to “ENABLE†by the arrow keys; Step 3: Select “RTC†ALARMDATE" press Enter, then set its value to "EVERYDAY", which means that the same operation is performed every day. In the same way, respectively, "RTC ALARM" HOURSâ€, “RTCALA RM MI NUT Eâ€, “RTM ALARM SECOND is set to “07â€, “55†and “00â€. This means that the boot time is “7:55:00†in the morning. After all settings, press F10 to save and restart. Since the BIOS of different motherboards is different, some motherboard settings may be different from the above, but just remember to find "WAKE UP" or "Resume by" in power management. The word "Alarm" will do, because this is the option to set the timed boot. Second, with the shortcut, boot automatically run display information file Step 1: Associate the display file with the display program. For example, the display file is "common.led", the program to open it is "LED.exe", just right click on "common. le d icon, click "Properties", click the "Change" button in the "General" option, find the program "LED.exe", click "OK" on it; Step 2: Generate a shortcut to the display file. Right click on the "Common.led" icon and click on "Create Shortcut" to bring up a "shortcut to Use the ".led" icon, then click "Start" and "Run" and "Browse" in the lower left corner of the computer display, find the "shortcut to common.led" file and confirm, copy the "" that appears in the "Open" column... …A shortcut To the usual .led.lnk "". Note: If you click "OK", you can directly open the display file "Common.led"; Step 3: Set the startup item in the Super Rabbit. Download the Super Rabbit software on the external network and install it on the LED display server computer. Open the "Magic Settings - Create your own system" in the "Bunny Tools", right click in the "Startup Program" and select "New Project" , paste "in the command line" D: LED shortcut to commonly used .led.lnk", the title is set by yourself. After this setting, the open opportunity automatically runs the display file "Common.led", which is the same effect as manually opening "Common.led". Technology 2: How to detect the quality of LED display pixels from the cell board "Pixel" is a unit used to calculate digital images. Just like a photo taken, digital images also have continuous tone and tone. If we magnify the image several times, we will find that these continuous colors are actually similar to many colors. The small square points are the smallest unit "pixels" that make up the image. This smallest unit of graphics can display a single stain point on the screen. According to the color principle, we know that red (R), green (G), and blue (B) are called three primary colors. These three colors can be combined to give any color from black to white. In the LED display classification, there are a monochrome display, a two-color display, and a full-color display. Monochrome is relatively simple, and only one of the three primary colors is required to achieve monochrome display. In practical applications, there are more red LED lights. In this case, a red LED is a pixel. The two-color display is similar to the monochrome display. You can achieve two colors by selecting any two of the three primary colors. In practical applications, choose red and green. When both red and green are on, yellow can be achieved. Therefore, the two-color display can realize three colors of red, green and yellow.
