How to modify the scrolling subtitles at the door

Question 1: How does the LED electronic screen (scrolling advertisement at the door) change the previous text? Who pressed it for you? Who are you looking for ~

I don't know if this thing has a small screen ~ but it should be set directly. If you want to change it, you have to find it for you.

The big screen is connected to the computer, and there is software in the computer to change the text ~

That's what I do ~ haha

Question 2: How to change the subtitles of the LED display screen in front of the store? The word change of the display screen is carried out by special software, and the content generated by the software is stored in the root directory of the U disk, depending on the software. It is impossible without software. If you don't know what card it is, you don't know what software it is. It is not difficult to tear down the screen or ask previous users, or find professionals to try the software one by one.

I hope I can help you.

Question 3: What are the scrolling subtitles in front of the store? It's called an led display. If you advertise in front of the store, you must register with the industrial and commercial department, or you will be fined. As for the physical principles, they are basically as follows:

LED is the abbreviation of English light emitting diode. Its basic structure is electroluminescent semiconductor material, which is placed on the shelf with leads and then sealed with epoxy resin to protect the internal core wire.

First, the principle of LED lighting

LED is made by injection electroluminescence principle, and its core part is a chip composed of p-type semiconductor and n-type semiconductor. There is a transition layer between p-type semiconductor and n-type semiconductor, which is called pn junction. In the pn junction of some semiconductor materials, when the injected minority carriers (electrons and holes) recombine with the majority carriers, the excess energy will be released in the form of light, thus directly converting electric energy into light energy. Pn junction with reverse voltage is difficult to inject minority carriers, so it does not emit light.

Second, the basic characteristics of LED light source

Compared with other light sources, LED light sources have the following basic characteristics:

1. Strong safety and reliability: LED adopts low-voltage power supply, and the power supply voltage is between 6 ~ 24V according to different products. Therefore, it is a safer light source than using high-voltage power supply, especially suitable for public places. Moreover, LED has low calorific value (cold light source) and almost no thermal radiation. It can accurately control the kind of light and its luminous angle, and the light color is soft and no glare. The built-in microprocessor system can control the luminous intensity and adjust the luminous mode to realize the combination of light and art.

2. Low power consumption: Under the same light intensity, the power consumption is one-eighth of that of incandescent lamps and one-half of that of fluorescent lamps.

3. High luminous efficiency: After decades of technical improvement, the luminous efficiency of LED has been greatly improved. For example, at present, the luminous efficiency of incandescent lamps and tungsten halogen lamps is 12 ~ 24 lumens/watt, fluorescent lamps are 50 ~ 70 lumens/watt, and sodium lamps are 90 ~ 140 lumens/watt, so the thermal effect of lamps is wasted. After improvement, the luminous efficiency of LED light source will reach 50 ~ 200 lumens/watt, and its light has good monochromaticity and narrow spectrum, and it can directly emit color visible light without filtering.

4. Strong applicability: a single LED is very small, and each unit LED chip is 3 ~ 5 mm square, so it can be made into devices with various shapes, which is very suitable for various changeable environments.

5. Good stability: If the percentage of LED light decay is generally considered by foreign scholars as the basis of its life, if the initial 50% LED light decay, its average life will reach 65.438+10,000 hours (more than ten years). Moreover, LED is small in size, light in weight, encapsulated by epoxy resin, high in strength, resistant to mechanical shock and vibration, and not easy to break.

6. Short response time (delay time of LED turning on or off): The response time of LED lamp is nanosecond (10-9 seconds), while that of incandescent lamp is millisecond (10-3 seconds).

7. Can change color: The same LED can change color by changing current. LED can conveniently adjust the energy band structure and band gap of materials through chemical modification, and realize multicolor emission of red, yellow, green, blue and orange. For example, an LED that is red at low current can turn orange, yellow and finally green with the increase of current.

8. Conducive to environmental protection: LED is an all-solid-state luminous body, which does not contain substances harmful to health such as mercury and sodium, and the waste can be recycled with little pollution.

Third, the application and prospect of LED

Based on the above advantages of LED, LED has been widely used in indicator lamp, signal lamp, large screen display, landscape lighting and other fields. In our daily life, we can see everywhere: the power indicator light of household appliances, telephones and so on. , dashboard (panel) lighting, anti-fog lights, brake lights, traffic lights, etc. Especially in recent years, with the development of semiconductor luminescent materials, the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), ultra-high brightness LEDs of various colors have made breakthrough progress; Chromaticity also realizes all colors in the visible light band, the most important of which is the appearance of ultra-high brightness white LED, which makes it possible for LED applications to leap into the ranks of efficient lighting sources. It has been pointed out that high-brightness LED will be one of the greatest inventions in the field of lighting after Edison invented incandescent light bulb.

Development and application of monochromatic LED

The earliest LED light source based on the principle of semiconductor pn junction appeared in the early 1960s. Used at that time ... >>

Question 4: How to change the words on the scrolling screen of LED door? Mine was given by someone else, and the words were changed with a USB flash drive. I am not as good as you.

1, you can copy a software where you buy Led lights.

2, there is no download online, and the downloaded things are not necessarily safe.

Question 5: Highlighting led display screen, advertising screen, finished screen, led door screen, scrolling subtitles, and how to debug outdoor monochrome display are all available in general software. The effects of various settings are quite comprehensive.

Set it to the style you want in the software and send it to u ***.

Question 6: The LED display at the entrance of the decoration shop shows the subtitle content. The word change of the display screen is carried out by special software, and the content generated by the software is stored in the root directory of the U disk, depending on the software. It is impossible without software. If you don't know what card it is, you don't know what software it is. It is not difficult to tear down the screen or ask previous users, or find professionals to try the software one by one.

I hope I can help you.

Question 7: How to set the data link of the door LED scrolling? Word 5 split screen parameter setting error.

Question 8: Does the installation of LED scrolling subtitles in front of the store require the approval of relevant industrial and commercial departments? The LED screen installed in front of the door shows the information of your own shop, so it is not an outdoor advertising publishing tool. Naturally, there is no need to go to the industry and commerce to publish and register outdoor advertisements. If your screen installation does not exceed your door factory, it does not belong to the occupation of the road. Urban management will naturally leave you alone. As long as you don't publish bad information.

Question 9: How to input the text content of led advertising scroll screen? Ask the manufacturer if the control procedures are different. Of course, different softwares have different methods.

Question 10: It's easy to remotely replace the LED subtitle billboard. Use SMS card or wifi card.
