The image display of LED uses an electronic light-emitting system to display the image conversion results of digital signals. The dedicated video card JMC-LED has emerged, which is based on a 64 bit graphics accelerator used on the PCI bus, forming a unified compatibility with VGA and video functions, allowing video data to be stacked on top of VGA data, improving compatibility deficiencies. Adopting a full screen approach to capture resolution, the video image achieves full angle resolution to enhance resolution, eliminate edge blurring issues, and can be scaled and moved at any time, responding to different playback requirements in a timely manner. Effectively separate red, green, and blue colors to improve the true color imaging effect of electronic displays.
Data reconstruction and storage
The commonly used memory combination methods currently include combination pixel method and bit level pixel method. Among them, the median plane method has significant advantages, effectively improving the optimal display effect of LED screens. By reconstructing the circuit from bit plane data, RGB data conversion is achieved, where different pixels are organically combined within the same weight bit, and adjacent storage structures are used for data storage.
ISP for circuit design
With the emergence of System Programmable Technology (ISP), users can repeatedly patch the shortcomings in their designs, design their own goals, systems, or circuit boards, and achieve the application functions of software integration for designers. At this point, the combination of digital systems and system programmable technology has brought new application effects. The introduction and use of new technologies have effectively shortened design time, expanded the limited usage range of components, simplified on-site maintenance, and facilitated the realization of target equipment functions. When inputting logic into the system software, the influence of the selected device can be ignored, and input components can be freely selected, or virtual components can be selected for adaptation after input is completed.
1. Switching order:
When opening the screen: Turn on the computer first, then turn on the screen.
When turning off the screen: Turn off the screen first, then turn off the power.
(Turning off the display screen without turning it off will cause bright spots on the display screen body, and the LED will burn out the light tube, resulting in serious consequences.).
The time interval between opening and closing the screen should be greater than 5 minutes.
After entering the engineering control software, the computer can open the screen and power on.
2. Avoid turning on the screen when it is completely white, as the system's surge is at its maximum.
3. Avoid opening the screen when it loses control, as the system's surge is at its maximum.
When the electronic display screen in one row is very bright, attention should be paid to turning off the screen in a timely manner. In this state, it is not suitable to open the screen for a long time.
4. The power switch of the display screen often trips, and the display screen should be checked or the power switch should be replaced in a timely manner.
5. Regularly check the firmness of the joints. If there is any looseness, please make timely adjustments and re strengthen or update the suspension parts.
When the ambient temperature is too high or the heat dissipation conditions are poor, LED lighting should be careful not to turn on the screen for a long time.
