How LED displays connect with mobile devices
In fact, one of the most important reasons for cell phones and ipads to control LED full-color display is to connect these devices, so are cell phones and ipads like computers that need a network cable to connect? The answer is no, only need to use to WIFI can be connected.
First, the cell phone and ipad control led full color display screen several methods
1.1, WIFI wireless control
System to mobile (cell phone, IPAD) for the console, the first time to realize the remote wireless control screen, all of its functions can be realized by the touch screen control, zero-second switching without lag. Really abandon the traditional keyboard, mouse, software instead of hardware.
Working principle: by adding a wireless router or other wireless devices, and the user's original wireless network for bridging, build a wireless LAN, convenient network control card into the wireless network, wireless network control.
Features: no wiring, easy installation and commissioning, fast data transmission speed.
Required equipment: bridge, wireless router (led full-color display on the application of the best choice of interchangeable antenna equipment, so that you can effectively receive the wireless signal).
Disadvantages: the communication distance mainly depends on the gain capacity of the bridge, the communication distance of the wireless router is relatively short, the signal across the wall is weak or no signal. Applicable to short distance places with wireless signals. If your display is in the area of wireless signal coverage, it is more simple, only need to led full color display screen and led full color display control card connected to the wireless router bridge to your wireless network, you can control the display on any computer in the network.
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, it will generate a virtual serial port and send data through this serial port.
1.3、GPRS wireless control
Working principle: GPRS module is powered up to complete the dial-up process and connect to the data center server.
After the GPRS module is powered up, it connects to the server in the data center, and the client accesses the server through the client software, and the server forwards the information.
1.4、4G full network pass wireless control
Working principle: basically the same as 3G/GPRS.
Characteristics: 4G full network pass (China Mobile, China Unicom, China Telecom full range of support), fast transmission rate, fully realize real-time control, send commands can instantly respond to the relevant control.
Second, cell phone and ipad control led full color display screen several functions
2.1, image preview, visualization operation
With ipad control screen, any function is visualized, at a glance, will play the cell phone, iPad, will control the LED screen curtain! Before switching, it is possible to preview the content of the upcoming playback, maximize the prevention of misuse, safe and reliable!
2.2, Brightness, volume, a key to any adjustment
According to the actual situation of the site, customers can at any time in the iPad one-key remote control screen brightness (from the brightest to the black screen) and volume, simple and convenient. Most importantly, any operation will not affect the use of the current screen body, without having to exit the current playback!
2.3 Support list editing
Before or during the use, customers can always play the program file classification, list sorting, file increase or decrease, as well as pre-monitoring. When playing video, you can set up single loop or list loop.
2.4 Picture-in-picture, four-screen and nine-screen switching with one key
Single-screen playback mode and picture-in-picture (support up to four sub-pictures, sub-pictures can be dragged and dropped size), four-screen, nine-screen, can be switched with one key, zero-second delay without lag; in multi-picture mode, double-click on any of them to switch between full-screen and window (audio synchronization).
2.5 Support PPT, Word, and other Office files playback.
In addition to the above features, the wireless screen control system also supports normal playback of Office files (including PPT animation), seamless switching between Office files, and seamless switching with video (i.e., it can support non-lagging playback of larger video files). A file can be placed in multiple windows, independent of each other, so as to pre-monitor the next screen, security.
2.6. Synchronized editing of subtitles, support for synchronous and asynchronous video recording
In the process of using, the user can synchronize editing letters, a key can be video recording, support for synchronous video and a video, the recorded file can be exported.
2.7 Support multi-screen synchronization
This system can support a control of multiple screens. By switching, you can control the playback content of each display separately, and can synchronize the control of multiple screens.
2.8 Other features
Power failure renewal: even if the iPad is turned off, the screen will still play in accordance with the original mode of playback without black screen playback;
External devices: support for cameras, DV, DVD players, laptops and other equipment signal direct connection, and can be synchronized to pre-supervise the live screen, can be switched with a key.
Third, cell phones and ipad combination program control led full-color display (with the main control secret box + LED video processor + WIFI) combination program main control secret box can also be replaced with millet box, the following main control secret box as an example:
3.1 The main functions realized
Through the cell phone (Android, Apple) system to control the LED display to play the content in the phone, the content contains conventional pictures, videos, etc..
3.2 Required functional devices:
(1) One Android/Apple system cell phone
2）One master secret box
3) One wireless router (need to connect to the Internet)
4) A set of led full color display
5) LED video processor-support HDMI or related HDMI conversion line (the main control box is HDMI interface)
3.3 control before the equipment need to complete the connection and playback file preparation:
(1) first led full-color display and LED video processor normal connection and debugging is completed
(2) the HDMI output of the main control box connected to the LED video processor and make the appropriate settings
(3) wireless router to open the wireless network, and the phone, the master control box at the same time connected to the same WIFI network
(4) cell phone according to the system to install a corresponding version of the LED master control system, and through the settings to connect to the master control box and the LED stage screen need to play the contents of the backup to the phone in advance
3.4 Specific operation method:
(1) through the master control system control will be cell phones, sharing computer video or photos through the way up to send directly to the master control box, the master control box to receive the secret box will directly play your customized video, picture files
(2) You can also play various videos in the Internet through the main control box.
