Description
Technical field
Technical field of liquid crystal display is the utility model is related to, relates more specifically to a kind of liquid crystal display die set and for the mould
The fixture of group.
Background technology
Liquid crystal display die set generally includes CTP（Capacitive Touch Panel, capacitive touch screen）、TFT-LCD
（Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-LCD）, backlight and in
Glue frame.Wherein CTP is one of key building block of touch display panel, has that sturdy and durable, reaction speed is fast, it is empty to save
Between, be easy to exchange many advantages, such as, be mainly used on the display panel of the products such as smart mobile phone, notebook computer, PAD.
TFT-LCD is used for editing photo, screen, document etc., has high-resolution, high color fidelity, high brightness, high-contrast, height
The features such as response speed.
It is typically that TFT-LCD is first bonded in group on the middle glue frame 4 of backlight when liquid crystal display die set assembles in the prior art
It is fitted together to obtain LCM, is then bonded CTP with LCM.Specifically as shown in figure 1, CTP1 includes protecgulum 11 and touch sensing
12, in advance protecgulum 11 and touch sensing 12 are fit together to be formed by optical cement 6 before liquid crystal display die set is assembled
CTP1, then the sides of TFT-LCD 2 are bonded on the continuing surface of the middle glue frame 4 in backlight 3 by tacky on two sides 5, then by CTP1
It is fitted in by optical cement 6 on the opposite sides of TFT-LCD 2.
Problems be present in above-mentioned liquid crystal display die set：
1st, because CTP1 peripheries are bigger than TFT-LCD 2, after TFT-LCD 2 is bonded entirely with CTP 1, by TFT-LCD 2
It is peripheral to be assembled in the positioning of the continuing surface of middle glue frame 4 in backlight 3, it can be covered by CTP 1, it is difficult to align, assembling is difficult；
2nd, CTP1 is glued on such a structure TFT-LCD 2, lower viscous backlight 3, the bearing up-down forces of TFT-LCD 2, easily causes box thick
Inequality, produce MURA problems；
3rd, because the backrest light 3 of TFT-LCD 2 positions so that gap d very little between TFT-LCD 2 and middle glue frame 4, although existing
There is the gap d that the upper theory of design is stayed in 0.1 ~ 0.2mm, but due to being to keep to the side to assemble, TFT-LCD 2 may be abutted after assembling
The medial surface of glue frame 4 in.Middle glue frame 4 can produce shrinkage phenomenon in low temperature, cause size to diminish, and then oppress TFT-LCD
2, TFT-LCD 2 is produced MURA problems.

Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As Figure 2-3, a kind of liquid crystal display die set includes cover plate 100, TFT-LCD 200 and backlight 300, the lid
Plate 100 includes protecgulum 110 and touch sensing 120, and the protecgulum 110 and touch sensing 120 are bonded by optical cement 600
Together.The TFT-LCD 200 includes polarizer 1, TFT substrate, filter substrate, the polarizer 2 to fit together, and this is
Prior art, it will not be repeated here.The cover plate 100 is when inner side by being fitted in one when optical cement and TFT-LCD 200
Rise and form touch control display plate.
The backlight 300 includes underframe 310, middle glue frame 320 and backlight module 330, the underframe 310 and middle glue frame 320
To carry the cladding backlight module 330, the middle glue frame 320 includes the first loading end 321 and the second loading end for engagement
322, the outside that first loading end 321 passes through the tacky on two sides phase the same faces of TFT-LCD 200 Nian Jie with the cover plate 100
Fit together, the top of second loading end 322 is accommodating the TFT-LCD 200, the He of the second loading end 322
Foam ring 400 is provided between TFT-LCD 200 to fill the gap between the second loading end 322 and TFT-LCD 200 to prevent
Dust is entered in backlight 300.The foam ring 400 requires high compression ratio, is held in the state of not compressed by second
Gap between section 322 and TFT-LCD 200 is filled up completely with.By the way that TFT-LCD 200 is bonded with cover plate 100, without with
Middle glue frame 320 or backlight module 330 are directly bonded, it is ensured that LCD is not acted on by external force, has good display effect.
The middle common used material of glue frame 320 described in prior art is expected for PC, and LCD is made up of glass, the thermal expansion system of PC material
Number is 65um/ (m. DEG C), and thermal expansion coefficient of glass 7.5um/ (m. DEG C), and both are differed greatly, and this is meant that in low temperature
In the case of, glue frame is more much greater than the size of LCD shrinkage, so that middle glue frame is urged to LCD, causes LCD to produce MURA problems.
As a further improvement, due to TFT-LCD 200, to be not required to glue frame 320 in relying on spacing, therefore can increase the sides of TFT-LCD 200
With the gap between the middle medial surface of glue frame 320.Between the sides of TFT-LCD 200 and the middle medial surface of glue frame 320
Clearance D for 0.3mm and more than, preferably 0.5mm, thermal coefficient of expansion and TFT-LCD 200 with specific reference to middle glue frame 320
Depending on length, to ensure that the shrinkage of the middle glue frame 320 will not be urged to TFT-LCD 200, solve in the limiting case
TFT-LCD 200 because by the shrinkage of middle glue frame 320 extruding and caused by MURA the problem of.
As a further improvement, the underframe 310 is metal frame, the position that the underframe 310 engages with middle glue frame 320 is prolonged
Locating dowel 311 is stretched, the corresponding locating dowel 311 of middle glue frame 320 offers positioning hole 323, the locating dowel 311 and positioning hole
323 grafting can effectively prevent middle glue frame 320 to be expressed to TFT-LCD200 because of the influence expanded with heat and contract with cold.
As a further improvement, the backlight module 330 includes optical film 331, light guide plate 332 and reflector plate 333, it is described
Optical film 331 is arranged on the exiting surface of the light guide plate 332, and the reflector plate 333 is located at the exiting surface phase of light guide plate 332
To another side on.The medial surface of underframe 310 is provided with luminescence component 312, and the luminescence component 312 is towards the light guide plate
332 incidence surface.The optical film 331, light guide plate 332, reflector plate 333 and luminescence component 312 are formed in the and of underframe 310
In the space of middle glue frame 320.
First cover plate 100 and TFT-LCD 200 is fit together during liquid crystal display die set assembling, then by backlight mould
Group 330 and the touch control display plate of middle glue frame 320 and cover plate 100 and TFT-LCD 200 touch control display plate pass through double-sided adhesive sticker
It is combined.Easily align during the liquid crystal display die set assembling of this structure, be easy to assembly, the liquid crystal display die set after assembling is shown
Natural rate of interest is high.
