In response to the development of the times, mobile phones and ipads are now equipped with more and more computer functions, that is, online office can be realized on mobile phones and ipads. Since mobile phones and Ipads can achieve most of the functions of computers, it is no problem to use mobile phones and ipads to control the led display. Then how do they control the led display and what is the principle.

In fact, one of the important reasons for the mobile phone and ipad to control the led display is to connect these devices, then do the mobile phone and ipad need a network cable to connect like a computer? The answer is no, just use WIFI to connect.

Several methods for mobile phone and ipad to control led display

1.1, WIFI wireless control

The system uses the mobile terminal (mobile phone, IPAD) as the control terminal to realize the remote wireless control screen for the first time. All of its functions can be realized by the touch screen control, with zero-second switching without freezing. Really abandon the traditional keyboard and mouse, and replace the hardware with software.

Working principle: By installing a wireless router or other wireless equipment, bridge the user's original wireless network to build a wireless local area network, and easily integrate the network control card into the wireless network for wireless network control.

Features: No wiring required, easy installation and debugging, and fast data transmission.

Required equipment: network bridge, wireless router (the application on the display screen is to select equipment with replaceable antennas, so that wireless signals can be effectively received).

Disadvantages: The communication distance mainly depends on the gain capability of the bridge. The communication distance of the wireless router is relatively short, and the signal of the partition wall is weak or no signal. It is suitable for places with wireless signals in short distances. If the area where your display is located already has wireless signal coverage, it is even simpler. Just bridge the wireless router connected to the led display control card in the led display to your wireless network, and you can use the intranet The display screen is controlled on any computer.

1.2, RF wireless control

Working principle: One end of the RF module is connected to the control computer, and the other end is connected to the serial port of the control card. After the computer installs the driver, a virtual serial port is generated and data is sent through this serial port.

1.3, GPRS wireless control

Working principle: After the GPRS module is powered on, it completes the dial-up process and connects to the data center server. The client accesses the server through the client software, and the server forwards the information.

1.4, 4G full Netcom wireless control

Working principle: basically the same as 3G/GPRS.

Features: 4G full Netcom (supported by all series of China Mobile, China Unicom, and China Telecom), fast transmission rate, fully realized real-time control, sending commands can instantly respond to related controls.

Analysis of the advantages and disadvantages of transparent LED screen and conventional display

Both conventional LED display and transparent LED display are a kind of LED display. LED display is a general term. Why is conventional LED display called conventional because it is the design when LED display was first born, and the most commonly used one is currently in the market. The most common use, such as: structure, shape, control, use, etc. are relatively conventional, all spare parts can be bought at will, no need to customize. So everyone gave it a conventional name.

The design principle of the transparent LED screen is the same as that of the conventional LED display. It is developed on the basis of the conventional LED screen. The conventional LED screen is opaque, and has a relatively thick structure and a relatively bulky appearance. The transparent LED screen adopts a light bar design, incorporates light-transmitting elements, and the overall structure is optimized, and the overall appearance looks more beautiful and high-end, with thinner thickness and lighter weight. Many advantages such as better heat dissipation, coupled with the update of the control system, make the control more convenient.

The transparent LED screen is based on the principle of conventional LED display, combined with the principle of the shutter structure, and the light bar is parallel to produce gaps to form transparency. At present, it is mainly used in the fields of glass curtain wall, stage art, commercial display, municipal engineering and so on. The comparison of the advantages and disadvantages of the transparent LED screen and the conventional LED display is mainly manifested in the aspects of product design, process technology and so on.

1. Structural features

Conventional LED display screens are relatively thick and heavy, including the box frame, modules, heat dissipation and other equipment. They are relatively heavy, with a conventional appearance and price comparison, and are not easy to maintain. Transparent LED screen, simple structure, aluminum profile structure and transparent PC panel, stylish and beautiful appearance. Because the province has transparent lighting, no additional heat dissipation equipment is needed. And there is no centralized layout of cabinet accessories. The weight of the same area size is more than 50% lighter than the traditional display screen.

2. Presenting the display effect

Traditional screens tend to have poor color reproduction, distortion, and color adjustability. Especially the small pitch makes it easy to mix colors. Transparent screen, transparent, bright, gorgeous, ultra-high refresh rate display screen floating. Symphony, attracting people's attention.

Three, installation and after-sales maintenance

Traditional screens are complex in structure and heavy in quality, and steel structure is required for installation. If they are installed on a fixed wall, the wall will be damaged, and outdoor installation will have safety hazards. Post-maintenance also requires special operations; the transparent screen, because it is transparent, can be installed indoors. The skeleton is fully equipped with movable locks, which is convenient and easy to install and operate. And the accessory module is not welded down, the 1/4 module of the card plug-in replacement module, gently push from the back of the module by hand, there is no need to remove the module, only the defective unit parts need to be replaced, and the maintenance is simple and labor-saving.

Fourth, product specificity

The traditional screen has strong resistance and the highest degree of protection can be IP67. Soft plastic embedded layout, the minimum spacing can be P0.8, and the display effect can reach ultra-high-definition. Transparent screen, because the lamp beads are exposed, and the texture is light, the protection level is the highest IP46. Due to the need for transparent specificity, the minimum distance can only be P3, and only clear results can be achieved.
