Description
[technical field]
The invention relates to a kind of LCD.
[background technology]
Because the liquid crystal itself in the panel of LCD is not luminous, thereby, for reaching display effect, a planar light source device is provided must for the LCD panel, as module backlight, to realize Presentation Function.
Prior art module backlight comprises light source, light guide plate and framework, light source is the incidence surface setting of relative light guide plate, the transmission direction that the light-guide plate guides light source emits beam, the light that line source or pointolite are transferred turns to the outgoing of uniform in-plane light to illuminate the display panels in the LCD.Framework is used for fixing each assembly of this module backlight.
A kind of LCD of prior art as shown in Figure 1, this LCD 1 comprises a display panels 10 and a module 20 backlight, this display panels 10 and module backlight 20 stacked settings.
This display panels 10 comprises a viewing area 11, a non-display area 12, a chip for driving 13 and flexible circuit board 14, this chip for driving 13 and flexible circuit board 14 are positioned at this non-display area 12, by anisotropy conductiving glue (Anisotropic ConductiveFilm, ACF) this chip for driving 13 is pasted non-display area 12, and by shading double faced adhesive tape (Masking Tape) end of flexible circuit board 14 is pasted non-display area 12, by this flexible circuit board 14 to chip for driving 13 input electric energy.
This module 20 backlight comprise brightening piece 21 on, once brightening piece 22, a diffusion sheet 23, a light guide plate 24, a circuit board 25, be arranged on a plurality of light-emitting components 26, a glue frame 27 and a reflector plate 28 on this circuit board 25, wherein, this light guide plate 24 comprises an exiting surface 241 and one and the bottom surface 242 that is oppositely arranged of this exiting surface 241.
This module 20 backlight can be assembled according to following order.At first, this light guide plate 24 is arranged on this glue frame 27, again this circuit board 25 is arranged in this glue frame 27, make be arranged on the circuit board 25 more than light-emitting component 26 lay respectively in a plurality of breach of this glue frame 27, again diffusion sheet 23, time brightening piece 22, last brightening piece 21 are successively set on the exit facet 241 of light guide plate 24, and reflector plate 28 are arranged on the bottom surface 242 of light guide plate 24.
The module backlight 20 that utilizes the shading double faced adhesive tape can fix this display panels 10 and assemble, the one side of this shading double faced adhesive tape is pasted display panels 10, and another side adhesive glue frame 27 reaches goes up brightening piece 21.
Yet, when utilizing the shading double faced adhesive tape to paste display panels 10 and module 20 backlight, flexible circuit board 12 can be folded into module backlight 20 bottom surfaces, at this moment, flexible circuit board 12 can produce internal stress at bending position, this internal stress is 25 liang of object pull-ups of circuit board of the shading double faced adhesive tape and the light-emitting component 26 of display panels 10 belows, thereby is easy to cause bad optical phenomenas such as light leak, and then influences display quality.
And, when utilizing the shading double faced adhesive tape to paste display panels 10 and module 20 backlight,, can cause module 20 bright dippings backlight inhomogeneous, and then influence display quality because of having the shading double faced adhesive tape on the last brightening piece 21.
[summary of the invention]
For the problem of bad optical phenomena appears in the LCD that overcomes prior art, be necessary to provide a kind of bad optical phenomena that overcomes, improve the LCD of display quality.
A kind of LCD comprises a display panels and a module backlight, this display panels comprises a viewing area, one non-display area and flexible circuit board, this viewing area and non-display area are adjacent, one end of this flexible circuit board connects non-display area, this module backlight comprises a framework, this framework comprises four sidewalls, these four sidewalls form a receiving space, be used to accommodate this display panels, wherein, on at least one sidewall of the corresponding display panels non-display area of this framework at least one projection is set, this projection is replaced the one side that deviates from this module backlight of this display panels non-display area.
Compared to prior art, owing on the sidewall of the framework of this LCD projection is set, this projection is replaced the one side that deviates from this module backlight of this display panels non-display area, thereby can offset the internal stress of the bending place generation of flexible circuit board, prevent internal stress pull-up display panels because of the bending place generation of flexible circuit board, liquid crystal panel is stablized affixed, thereby prevent bad optical phenomenas such as light leak, and need not use the shading double faced adhesive tape to paste display panels and module backlight, avoid bright dipping inhomogeneous, and then improve the liquid crystal display quality.
