Abstract
A kind of light leakage rear projection display, including being arranged at the liquid crystal panel of metal framework end face, it is arranged at metal framework other end and is provided with backboard, reflector plate is disposed with backboard, light guide plate and blooming piece, liquid crystal panel is apart from 10 ~ 15mm of blooming piece, liquid crystal panel, glue frame connection is set between backboard and metal framework, the section of the glue frame is T fonts, extinction plate is provided with glue frame and the horizontal raised line of liquid crystal panel, the 45 degree of settings of the extinction plate and horizontal plane, the horizontal raised line upper surface is apart from 6.6 ~ 7.6mm of liquid crystal panel, apart from 7.7 ~ 8.7mm of blooming piece, the metal framework is provided with horizontal extension with backboard junction, backboard is crimped on extension.Light leak, simple structure is effectively prevented to be easily installed and manufacture.
Description
Technical field
The present invention relates to the viscous curtain technical field of DLP, more particularly to rear-projection Display Technique.
Background technology
Rear-projection " is exactly the television set of rear projection.One kind makes use of projection and principle of reflection, the TV imaging system that screen and optical projection system are placed in one.In projection display apparatus, it is divided into orthographic projection by its projection pattern Projection Display（Front Projection）With back projection two ways.Rear-projection (Rear Projector) is for front projector (Front Projector).Briefly, it is the same side that observer and scialyscope are located at reflective viewing screen just to throw, and is mapped to screen from projector illumination out, it is seen that the light returned of screen reflection, the maximum light that is not both liquid crystal-spliced with BSV have passed through reflection with refraction to observer；Rear-projection is the both sides that observer and scialyscope are located at rear projection screen, by bottom of the scialyscope in fuselage, has part light transmission when being mapped to translucent rear projection screen from projector illumination out, and observer is it is seen that the light that transmits.Due to being integrated for scialyscope and screen, the user of back projection TV need not carry out pH effect to system so that its ease of use greatly exceed front projection machine.Although existing rear projection display product is sealed with glue bonding, due to the permeability of light, easily liquid crystal display screen or the phenomenon of generation light leak, so as to affect the quality of picture, have much room for improvement.
Content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided one kind effectively prevents light leak, simple structure, the light leakage rear projection display for being easily installed and manufacturing.
For realizing the object of the invention, there is provided technical scheme below：A kind of light leakage rear projection display, it is characterized in that including the liquid crystal panel for being arranged at metal framework end face, it is arranged at metal framework other end and is provided with backboard, reflector plate is disposed with backboard, light guide plate and blooming piece, liquid crystal panel is apart from 10 ~ 15mm of blooming piece, liquid crystal panel, glue frame connection is set between backboard and metal framework, the section of the glue frame is T fonts, extinction plate is provided with glue frame and the horizontal raised line of liquid crystal panel, the 45 degree of settings of the extinction plate and horizontal plane, the horizontal raised line upper surface is apart from 6.6 ~ 7.6mm of liquid crystal panel, apart from 7.7 ~ 8.7mm of blooming piece, the metal framework is provided with horizontal extension with backboard junction, backboard is crimped on extension.
Preferably, extension is provided with light-absorption layer with the backboard place of crimping.
Preferably, the back plate surface is provided with square groove, square groove, and inlay card has reflector plate, light guide plate and blooming piece successively.
Beneficial effect of the present invention：The present invention enormously simplify mounting structure, effectively be prevented light leak by the structure of change glue frame.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Embodiment 1：A kind of light leakage rear projection display，Including being arranged at the liquid crystal panel 2 of 1 end face of metal framework、It is arranged at 1 other end of metal framework and is provided with backboard 3、Reflector plate 4 is disposed with backboard 3、Light guide plate 5 and blooming piece 6，Liquid crystal panel 2 is apart from 610 ~ 15mm of blooming piece，Liquid crystal panel 2、Arrange glue frame 7 to connect between backboard 3 and metal framework 1，The section of the glue frame 7 is T fonts，Extinction plate 7.2 is provided with glue frame 7 and the horizontal raised line 7.1 of liquid crystal panel 2，The 45 degree of settings of the extinction plate 7.2 and horizontal plane，7.1 upper surface of horizontal raised line is apart from 2 6.6 ~ 7.6mm of liquid crystal panel，Apart from 6 7.7 ~ 8.7mm of blooming piece，The metal framework 1 is provided with horizontal extension 1.1 with 3 junction of backboard，Backboard 3 is crimped on extension 1.1.Extension 1.1 is provided with light-absorption layer 8 with 3 place of crimping of backboard.3 surface of the backboard is provided with square groove 3.1, and in square groove 3.1, inlay card has reflector plate 4, light guide plate 5 and blooming piece 6 successively.
