Description
Technical field
The utility model belongs to the large-screen splicing technical field, is specifically related to a kind of seamless large-screen splicing display unit.
Background technology
Present jumbotron both domestic and external all adopt liquid crystal panel LCD, plasma PDP and DLP etc. independently display unit carry out physics and be spliced.Because the reduction of the production cost of liquid crystal panel LCD, plasma PDP, and the little power consumption of they intrinsic low pressure, flat structure, display message amount big, be easy to colorize, electromagnetic-radiation-free and X ray (being beneficial to information privacy), long-life, free from glare, do not stimulate the characteristic of human eye more and more to be subjected to liking of jumbotron user human body safety.
But, because more or less existing, the restriction of manufacture craft and the physical characteristics of itself shows dead band (can not show or show back the framed of packed material blocks) through the display unit after the encapsulation because each display unit physically all is independently and all to have oneself independently to encapsulate.When carrying out tiled display, formed bigger slit, influenced the visual effect of picture in splicing place with so two or more display units.
The domestic and international at present disposal route to this slit has two kinds:
One, ultra-thin material is adopted in the encapsulation of display unit, so that reduce the screen splicing space.
This method can only reduce the splicing space, and can not eliminate the space, and the size in space depends on installer's the technical merit and the material thickness of employing.
Two, the flexible cord of the display panel of most display unit all is to draw from the both sides of panel, and it is very tiny so just to have determined that the encapsulation frame of panel can not be done.
Three, simply adopt the way that on display unit, adds lens change optical link.
This way has certain feasibility in theory, but operability is very poor in actual engineering, and reason is as follows: the independent displaying unit in the large screen system is often many, and the lens that are added in the middle display unit of whole screen can't be fixed; Because the colour temperature aberration of each separate unit has certain difference, especially degree of aging can be variant behind the long-play, like this can be variant to the light curvature of lens; During light process lens, lens can absorb light and get intensity, can influence visual effect; In the actual installation process, the slit of screen can not uniformity because lens are different with the material of display unit, so lens and display unit the degree of expanding with heat and contract with cold also different, the visual effect temperature influence of whole screen is bigger, so lens need be after the installing of screen, according to the result who measures every lens of processing separately, and because the parameter of every lens is different, not can manufacture, cause the cost height, long in time limit, problem such as quality is unreliable.
