【 Weak current college 】 building large-screen display and touch screen system 】

In as people increasingly high demands on vision, imaging devices, or get a fast development, the large-screen display devices have rear-projection TVs, projectors, plasma TV (PDP), LCD TV (LCDTV), large screen TVs (CRT) and big vision super bright light emitting diodes (LED) display. The following is a building on the large screen display and touch screen for practical application.
1 Overview
Modern society has entered the modern information age, information dissemination, occupies an increasingly important role, while people for Visual media have an increasingly higher demand, demand media Visual and rapidly disseminate information, lively, and eye-catching. In order to meet the increasingly high visual requirements, to retain the old customers, the more you want to continue to attract new customers, this requires that we constantly, in a timely manner to the public announcement of their diversified services, attract large numbers of customers. This works in a prominent position set indoor dual-color led display to show various news and current events, notifications, enterprise promotion and so on, the establishment of a public electronic information bulletin system. The so-called "video screen", the LED screen and control your computer monitors have dots corresponding mapping, video screen is gray control, and synchronization with the computer monitor, so you can play the animation.
A prominent position on both sides of the Hall set up a touch screen, touch screen, we removed complex keyboard commands that enable customers to focus on what they are looking for. By touching the screen on the appropriate icon, people can quickly turn their attention focused on their favorite columns, the columns of the relevant information quickly identify the content they care about. The touchscreen is that we can get the most direct and simple interface. We have a majority of the members of the public is limited computer knowledge, the touch screen do not need to have computer knowledge. Use it to query internal structure, the company locations, departments, contact phone and other information, establish business headquarters public electronic information query system, public electronic information bulletin system and public electronic information query system together constitute public electronic information display system. Public electronic information display system through the management system, connected to a public electronic information display system server, over the Organization, management and control to display various types of information.
2 system design principles
The programme is designed in the spirit of nature, relevance, openness, reliability, and affordability and design principles.
Advanced
At present, the large-screen display system market and touchscreen system of manufacturers on the market, many sizes is not a very big companies do not have their own technology development strength, the technique still in the early days of technical standards, such products while the price is cheaper, but the performance comparison between backwardness and reliability is poor. We design in ensuring product maturity and reliability, the selection of representatives of the most high technological level of products that guarantee the product's technical advancement.
Usability
Large-screen display system and touch-screen system product specifications, some small changes of parameters may cause large changes in the price and Visual effects. In the design, the spirit of the principles for the sake of customers, we will always put the needs of customers in the first place, it is first necessary to ensure that products are able to complete the client's functional requirements, do of the practical and applicable.

Open
Equipment integration and linkage between the future intelligent product development trend display and other follow major standard communication protocols of Internet devices.
Reliability
Large-screen display system and touch-screen system is generally installed in very high places, quality problems are directly attributable to a bad influence and maintenance will interrupt the normal use of the product. Therefore require product reliability is very high, in the design we strictly follow the failure rate is below industry standards and industry average of principles for product selection.
Economics
Economics for all times is the owner of the system's basic requirements in the design we will customers think, optimal design of the system and to ensure that in implementing the user function needs of the premise, as far as possible, consider saving investment for our clients.
