1 BIOS setting fixed-point automatic power on every day
Step 1: start the LED display server computer, press del, enter BIOS, and then select "power management features"
, enter. Find the item "restore on AC / power loss" in the power window, press enter, and then set its value to "power on" through the direction key;
Step 2: select "resume onrtc alarm" and press enter, and then set its value to "enable" through the direction key; Step 3: select RTC
"Alarmdate" press enter, and then set its value to "every day", indicating that the same operation is performed every day. According to the same method, respectively "RTC alarm"
"Second" is set to "07", "55" and "00", which means that the startup time is "7:55:00" in the morning. After all settings are set, press F10 to save and restart.
Because the BIOS of different motherboards is different, the settings of some motherboards may be a little different from those above, but just remember to find "wake up" or "resume by" in power management
The word "alarm" is OK, because this is the option to set the timed startup.
2 With the help of shortcuts, the display information file is automatically run after startup
Step 1: associate the display file with the display program. For example, the display file is "common. Led", and the program to open it is "led. Exe". Just click "common. L e" with the right mouse button
D "icon, click" attribute ", click" change "button in the" general "option, find the program" led.exe ", and click" OK ";
Step 2: generate a shortcut to the display file. Right click the "common. Led" icon and click "create shortcut" to display a "shortcut to"
Click "common. Led" icon, then click "start", "run" and "Browse" in the lower left corner of the computer display screen, find the "shortcut to common. Led" file and confirm it, and copy the ""... Shortcut in the "open" column
To the common. 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 Internet and install it into the LED display server computer. Open the "magic settings - create your own system" in the "rabbit tool", right-click in the "startup program", select "new project", and paste it in the "command line"
D: Led shortcut to "common. Led. LNK", the title is set by yourself.
After this setting, the startup will automatically run the display file "common. Led", which has the same effect as manually opening "common. Led".
Technology 2: how to detect the quality of LED display pixels from the unit board
"Pixel" is a unit used to calculate digital images. Like photographic photos, digital images also have continuous shades. If we enlarge the image several times, we will find that these continuous tones are actually composed of many small square points with similar colors. These small square points are the smallest unit "pixel" of the image. This smallest graphic unit can be displayed on the screen, usually a single dye point.
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 obtain any color from black to white. In the classification of LED display screen, there are monochrome display screen, two-color display screen and full-color display screen. Monochrome is relatively simple. You only need to select any one of the three primary colors to realize monochrome display. In practical application, there are many red LED lamps. In this way, a red LED is a pixel.
The two-color display screen is similar to the monochrome display screen. As long as any two of the three primary colors are selected, the two-color display can be realized. In practical application, red and green are often selected. When red and green are on at the same time, yellow can be realized. Therefore, the two-color display can realize three colors: red, green and yellow.
