Abstract
The invention discloses a liquid crystal dimming projection display system. The system is formed by a dimming screen and a projection system. The dimming screen is formed by a dimming film, glass and a touch control system. The projection system is formed by a projector and a multimedia function system. Through effective integration of the dimming screen and the projection system, various magic states and conversion of transparency, opacity, projection, perspective projection, double-sided imaging and 360 degree visuality can be realized. The system is widely applied and a brand new multimedia display platform which can attract a client to publish information, recommend a product, and carry out public relation propaganda and the like is provided for activities of education, medical treatment, media propagation, an exhibiting company and the like.
Description
Technical field
The invention belongs to display device, more particularly, to a kind of liquid crystal light modulation projection display system.
Background technology
Not only cost is high for large-scale LCD TV in the market or laser television, and single function, it is impossible to meet the requirement of client, constantly improves with society, people have requirements at the higher level to life, needs to develop a feature richness and the high display device of cost performance.
It is known that projection TV is more cheap than LCD TV, especially to large scale, price difference is even more substantially.When size is more than 70 inches, the price of LCD TV will rise suddenly, because price is too high, 100 inch liquid crystal TVs have been no longer belong to the consumer goods.Further, since projection can provide more tonal gradations and color, the quality of projection image is higher than all known other technology, such as LCD TV or plasm TV.Meanwhile, projection can provide extremely many colors so that the personage of projection or scenery just seem and more have levels, softer, closer to real-world object.Therefore develop a large-sized projection display system to be extremely necessary.
Light modulation film is by two sheets of flexible transparent conductive film and one layer of polymeric dispersed liquid crystal material（PDLC）Constitute, during power-off, scattered power and Penetration ration are attained by higher state, it is used for doing back projection screens, effect outclass curtain, if light modulation film can be combined a liquid crystal light modulation projection display system of exploitation with shadow casting technique, this system can provide a kind of brand-new media concept for client, will be also that display and demonstration field has breakthrough Innovation System.
Content of the invention
It is an object of the invention to provide a kind of liquid crystal light modulation projection display system, this system is made up of light modulation screen and optical projection system, light modulation screen is by light modulation film, glass, touch-control system forms, optical projection system is made up of projecting apparatus and multimedia capable systems, by effectively integrating light modulation screen and optical projection system, enable transparent, opaque, projection, perspective projection, double-face imaging, 360 ° of visual various mystery states and conversion, for education, medical treatment, broadcasting media, the activity such as exhibiter provides brand-new attracting clients, release news, promotion product, the multimedia display platform of PR publicity etc..
The present invention is made up of two large divisions, is light modulation screen and optical projection system successively.
Described light modulation screen is made up of light modulation film, glass and touch-control system, and light modulation film and touch-control system are respectively placed in the two sides of glass, and touch surface is visual operation face, and light modulation face is the back side, and projection ray is from light modulation face incidence.
Described light modulation film can be any light modulation film, in order that drop shadow effect is optimal, preferably high fog light modulation film, i.e. and OFF state mist degree >=97% of light modulation film.
Described glass can be any glass, in order to farthest reduce the reflection in glass viewing face, preferably anti reflection glass.
Described touch-control system can be any system, and large scale screen is preferably infrared touch-control system.
Described optical projection system is made up of projecting apparatus and multimedia capable systems.
Described projecting apparatus can be any projecting apparatus, in order to reach optimal display effect, need to select projecting apparatus according to the size of the main application of device and screen, preferably high definition, ultrashort burnt and low-power consumption.
Described multimedia capable systems, refer to the function system that Projection Display is combined with computer multiplexing technologies, can be according to customer demand flexible configuration application system, family is mainly viewing, games system, community is mainly inquiry, display systems, and market is mainly publicity, product introduction and and Customer Interaction system etc..
This liquid crystal light modulation projection display system manufacture craft is simple, the mode of production can flexibly be selected, can make in factory, also can make at the scene, factory makes mainly for brand-new building or integral type liquid crystal light modulation projection display equipment, field fabrication is primarily directed to existing building, such as market show window transformation, subway promotional system transformation etc..
Preparation method in factory for this device is as follows：With UV glue/AB glue/double faced adhesive tape, light modulation film is attached on glass first, then touch-control system is pasted the another side in glass with Special two-side glue, then whole screen is fixed on inframe and forms complete projection screen, finally again this screen is arranged on fixing position, projecting apparatus and multimedia capable systems are configured, a complete liquid crystal light modulation optical projection system can complete.
This device preparation method at the scene is basically identical with factory preparation method, unique difference is not need to prepare in advance glass, directly pad pasting is carried out on existing glass, touch-control system is installed, after edge is processed and is decorated, projecting apparatus and multimedia capable systems are configured, a complete liquid crystal light modulation projection arrangement can complete.
Brief description
Fig. 1 is the configuration diagram of the present invention.
