  As the LCD video wall ‘ s appearance,solving all kinds of flows of the traditional TV wall.Scheduling and engineering application provides the best big screen display system for convenient,comprehensive, real-time display system of video information, especially the remote real-time command. The characteristics of the LCD video wall: 1、Long service life and low maintenance costs. LCD is the longest service life of the display device and its itself is very long service life.Even the back light part of the shortest life, also is as high as more than 50000 hours, and even use over such a long time, also will affect the brightness.Simply replacing the back light bulb can restore the original bright beautiful color. 2、Viewing angles. Viewing angle used to be a big problem restricting LCD for early products,but the problem has been completely solved by the constant progress of liquid crystal technology. 3、High resolution, beautiful picture.The distance of LCD is much smaller than plasma and the physical resolution can easily reach and exceed high definition standard. LCD brightness and contrast is very high, colorful, BSV LCD technology for flat surface display completely no curvature, image stabilization is not flashing. 4、Ultra-thin light. The characteristics of the LCD with thin thickness, light weight, can be easily splicing and installation. Special 40 inches LCD screen, the weight is only 12.5 KG, the thickness of less than 10 cm, this is can't be matched by other display device. 5、Low consumption, low calorific value. LCD device, low power, low fever has been praised by people. Small size LCD screen costs energy is less than 35W, and the inches over 40 LCD screen, its power is only about 150W, only about a third to one quarter of the plasma. 6、Long time between failures, maintenance cost is low. Liquid crystal display device is the most stable and reliable, because of the heat is small, the device is stable, it will not cause components high temperature damage. .

With the popularity of smart phones, capacitive touch technology has been steadily progressing. All around us, smart flat, multi-function display one machine, subway ticket machines, bank queuing machine, mall advertising, widely distributed in just a finger touches the touch screen can be a variety of operations. Touchscreen convenience unnecessary to say, but it's the type of technology I am afraid that most people do not understand. Including surface acoustic wave touch screen, infrared, resistive, capacitive, etc., wherein the capacitive touch screen with its excellent sensitivity, clarity and light transmittance gradually become mainstream touchscreen devices. Touch screen application trends leading advanced products for users provide leisure life more easy and convenient material conditions. Provide a basis for the creation of a better, happier life.   These products with smooth multi-touch technology, allowing users to have a better touch experience in the operation, but the touch screen can also identify clicks from multiple points on the screen, touch action and respond. Capacitive touch screen sensitivity and accuracy is satisfactory; 16: 9 wide-screen high-definition wide viewing angle LCD panel to ensure illustrations glance; aluminum casting pressure display frame exquisite appearance, feel comfortable; three-dimensional display with curved bracket perfect match easy to install, stable structure, placed in shopping malls, conferences, education, government agencies slim, finger point, recalling the tragic. People quickly into self-expression, the joy of the realm of passion. Wall is also a capacitive touch screen, can be hung on a wall or flush mounting, so you can save the limited interior space, allowing users to more freely entertainment, but also can decorate the indoor environment.   Android operating system capacitive touch one machine is a stand-alone device similar to a computer, which is pre-installed on phones and tablets popular Android operating system, integrated multimedia decoding, HDMI, LAN, Bluetooth, WIFI technology, support for popular video and computer picture format, you can also add USB and SD memory card, using almost the same operation as a desktop computer, keyboard and mouse, of course, not by a finger touch. Czech electric shock for touch capacitive touch screen is 16: 9 wide screen, 1920X1080 full high-definition LCD panel, the picture exquisite eye-catching. Touch screen mounted on the unique curved frame, beautiful appearance, solid structure, it is also more convenient to move. This touch one machine, as well as wall-mounted and desktop varieties, provide user interactive experience, to achieve learning, interaction, entertainment and conferences. Display a variety of installation, which allows the use of more convenient, make the room more beautiful, full of pride leaving users more free and easy to release.

Industrial touch one machine has the following several advantages:   1, stylish, slim compact. Highly integrated design simplicity. 2, touch one more space than the average desktop. LCD touch one machine is a host and LCD monitor, speakers combined into one machine that will host the hardware are placed behind the liquid crystal display, and try to compress it up, as well as built-in speakers, it's possible volume small, which enables users to place the machine saves space. This "high cost of land," city users is significant. 3, touch one of the moderate price. Highly integrated one machine, it is not to be expensive? And many friends, read some article said that after the high price of LCD one machine, also began to think that it really should be. But in-depth understanding of it after the fact is not the case. 4, good mobility, high portability. Since the liquid crystal touch one set of host, display and speakers, and therefore, the volume and the total weight to be smaller than the average desktop confidential, only ten kilograms, greatly facilitates the user to move the machine. Its internal integration is high, the parts of the connection leads directly from the PCB, eliminating the need for many past data cable, additional compact body also eliminates the need for conventional large packaging and transportation costs 5, touch one not only save space, but also reduces the cost of living, you save the high tariffs. A typical PC power from about 200W to 400W or more (depending on the configuration, performance, and availability). ARM-based embedded industrial machine, from 7 inches to 15 inches more than the power consumption is only 3W to 20W. As for application development, as long as ordinary PC PC software programming personnel can quickly master the basic familiar based on embedded WinCE ARM architecture, Linux, android programming. Because the basic software developers need only call to a simple API function, the underlying work, manufacturers have done very refined.
