In informationalized and digitized times ,the deciders need to learn, analyse , handle and grasp a mass of information data by conference .In this situation it is unrealizable to adopt traditional method that rely on one projector .Therefore ,we research and develop desktop LCD lifting system .A 15"－19" LCD is provided for every conference seat to offer more convenient auxiliary display terminal to conventioneers . When in use they touch off controller panel ,and the screen can be opened automatically up to desktop .The system can be widely used for various fields such as multimedia conference system ,TV conference system, command and dispatching system, production analysing system, financial analysing system, and conference simultaneous interpretation  system, etc.

Characters：

1 Panel: Aluminum alloy wire drawing or sand blasting panel, edge polishing treatment , top grade and utility ,suitable for installation and usage of more conference desk.

2 Angle of elevation : 10 degree fixed angle of elevation after lifting, according with human engineering ,which makes conference more orderly and beautiful.
3 Control : Support RS485 protocol, physical Dialing code ,preventing losing code of centralized control .
4.Button: Compared to thin film button ,plastic one improving useful life , enormously decreasing the customer service problems.
5.Structure : adopting spatial isolation structure ,avoiding data line damage caused by machine long running .
6.Transmission: double chain transmission mode ,more stable and permanent compared to other transmission mode .
