In order to respond to the development of the times, mobile phones and iPads now have more and more computer functions, that is, online work can be realized on mobile phones and iPads. Since mobile phones and iPads can implement most of the computer’s functions, it is no problem to use mobile phones and iPads to control the LED display. So how do they control the LED display and what is the principle?
In fact, one of the most important reasons for mobile phones and iPads to control the LED display is to connect these devices. Do mobile phones and iPads need a network cable like a computer to connect? The answer is no, just use WIFI to connect.
Several Methods of Mobile Phone and iPad to Control LED Display
WIFI wireless control
The system uses a mobile terminal (mobile phone, IPAD) as the control terminal, and realizes remote wireless screen control for the first time. All its functions can be realized by touch screen control. Zero-second switching is not blocked. Really abandon the traditional keyboard, mouse, software instead of hardware.
Working principle: By installing a wireless router or other wireless equipment, bridge the user’s original wireless network, build a wireless local area network, and easily integrate the network control card into the wireless network for wireless network control for Novastar TB3.
Features: No wiring, convenient installation and debugging, fast data transmission speed.
Required equipment: network bridge, wireless router (applied on the display is a device that selects a replaceable antenna, so that it can effectively receive wireless signals).
Disadvantages: The communication distance mainly depends on the gain capability of the network 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 short distance wireless signals. If there is wireless signal coverage in your display area, it is even simpler. You only need to bridge the wireless router connected to the LED display control card in the Linsn to your wireless network, and you can access the internal network. Control the display on any computer.
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 control card serial port. After the driver is installed on the computer, a virtual serial port is generated and data is sent through this serial port.
GPRS wireless control
Working principle: After the GPRS module is powered on, it completes the process of dialing up to the Internet and connects to the data center server. The client accesses the server through the client software, and the server forwards the information.
4G full Netcom wireless control
Working principle: Basically the same as 3G / GPRS.
Features: 4G full Netcom (supported by China Mobile, China Unicom and China Telecom), fast transmission rate, fully real-time control, and sending commands can instantly respond to related controls.
