Some simple knowledge about LED displays

The upstairs was very professional and good! I saved it.

First of all, the LED display of the new screen display can be used for outdoor display and indoor display. In terms of outdoor display, its brightness is larger, the waterproof performance is good, and the wind resistance is strong for slag removal, while in the indoor display, its resolution is high, the color reproduction is accurate, and the display effect is more beautiful. Secondly, it can also support a variety of file formats, such as **, **, text, etc., and can be remotely controlled and managed through network connection, which is very convenient.

In addition, the LED display of the new screen display also supports automatic brightness sensing system and intelligent interactive display technology, which can automatically adjust the brightness of the screen according to the ambient brightness, realize alarms, prompts and other functions in special circumstances, and provide an interactive user experience.

For how to choose an LED display, we recommend considering the following aspects: Look at the pixel density, that is, the line density, spacing density and point density of the display to ensure that the display quality is excellent; Look at the brightness and color reproduction, it depends on the specific occasion; Looking at the angle of view, BTG should ensure that the picture is clearly visible and not affected by the angle; Look at the curtain wall splicing technology to ensure the accuracy and seamlessness of picture segmentation; Looking at the after-sales service ability, there is a great guarantee for maintenance and use.

To sum up, the LED display with the new screen display can meet the needs of different occasions, and has a variety of intelligent functions, and can also enjoy professional after-sales service guarantee.

Shenzhen Dayuanneng Technology Engineer Huangshi will answer for you:

What are the specific functions of the LED display.

1. Information release function: miss late talk.

1) It can display all kinds of computer information, graphics, drawings and.

2. Three-dimensional animation.

2) There are a variety of Chinese characters and fonts to choose from, and you can also input English and French.

German, Greek, Russian and Japanese.

and many other foreign languages;

3) The broadcast system has multi-class software, which can flexibly input and broadcast a variety of information; Text information can be scrolled, rolled lines, introduced into the lead out mode, can be moved up, moved left, and the message can be broadcast in a loop. Font and font size can be arbitrarily selected, and the speed can be set back to touch, and multiple messages can be broadcast at the same time, or broadcast at the same time with animations and images.

4) Date, time, or string can be displayed.

4) Brightness, contrast.

Saturation and chromaticity can be adjusted by software, and the adjustment range is 256 levels;

5) It has three display modes: overlap (VGA+VIDE), image (video) and VGA;

6) It has the function of video image compression control.

7) It has the function of display synchronization.

8) Use the line-double function to convert the staggered picture into a non-staggered screen for movement compensation;

According to the display base color, it is divided into monochrome, two-color, and full-color! The installation location is divided into indoor, semi-outdoor, and outdoor!! It has a wide range of uses, such as billboards, door screens, square screens, etc!!

Abstract: At present, with the increasing development of China's LED display industry, the LED large-screen screen display in the streets and alleys of major cities has gradually increased. While we enjoy the economic benefits brought by LED electronic screens, some businesses with LED electronic displays do not fully understand the precautions for the operation and use of LED electronic screens, resulting in shortening the life of LED electronic displays.

Here, the precautions for the operation and use of LED electronic display are analyzed to ensure the safe and normal operation of the LED display system! 1. Precautions for switching on and off LED displays.

1. Switching sequence:

When the screen is turned on: the computer is turned on first, and then the screen is turned on.

When the screen is turned off: the screen is turned off first, then the computer is turned off.

If you turn off the computer without turning off the display screen, it will cause high highlights on the screen and burn the lamp, with serious consequences. )

2. The screen opening and closing time interval should be greater than 5 minutes;

3. After the computer enters the engineering control software, the screen can be turned on and powered on.

4. Avoid opening the screen in the state of full white screen, because the impulse current of the system is the largest at this time.

5. Avoid turning on the screen in a runaway state, because the impulse current of the system is the largest at this time.

6. When the ambient temperature is too high or the heat dissipation conditions are not good, you should be careful not to open the screen for a long time.

7. When a line of electronic display is very bright, attention should be paid to turning off the screen in time, and it is not appropriate to open the screen for a long time in this state.

8. The power switch of the display screen often trips, and the screen body should be checked or replaced in time.

9. Regularly check the firmness of the hook. If there is any loosening phenomenon, pay attention to timely adjustment, re-reinforcement or update the hanging parts.

10. According to the environmental conditions of the large-screen display screen and control part, avoid insect bites, and place rodenticide if necessary.

2. Changes and precautions for changes in the control part.

1. The power cord of the computer and the control part cannot be reversed, and should be plugged in strictly according to the original position. If there are peripherals, after the connection is completed, the case should be tested to see if it is live.

2. When moving the computer and other control equipment, check whether the connection line and control board are loose before powering on.

3. The position and length of the communication line and flat connection line cannot be changed at will.

4. If it is found that there is an abnormal appearance such as short circuit, tripping, wire burning, and smoke after moving, it should not be repeatedly powered on for testing, and the problem should be found in time.

3. Precautions for software operation and use.

1. Software backup: win2003, winxp, applications, software security programs, databases, etc., it is recommended to use "one-click restore" software, which is easy to operate.

2. Proficient in installation methods, original data recovery, and backup.

3. Master the setting of control parameters and the modification of basic data presets.

4. Proficient in the use of procedures, operations and.

5. Check for viruses regularly and delete irrelevant data.

6. Non-full-time personnel, please do not operate the software system.
