Background technology
With work growth in the living standard, a development trend of TFT LCD module is to 3D display development.Current 3D shows mainly spectacle, and spectacle mainly has again three kinds of modes: aberration formula, polarization type and active-shutter.Aberration formula uses red-indigo plant to wait colour filter 3D glasses, and structure is simple, with low cost, but 3D display effect is also the poorest.Polarization type will use passive type polaroid glasses, and the 3D rendering effect colorimetric differential of its display is slightly good, but higher to the brightness requirement of display device.Active-shutter glasses use shutter type 3 D spectacles, and its complex structure, display effect is relatively better.
There is following shortcoming in spectacle: common aberration formula glasses display effect is poor, the shortcomings such as polaroid glasses are higher to display device brightness requirement, and active-shutter glasses exist complex structure, fragile, and equipment investment is large, uses the 3D technical user of spectacle to experience bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of principle simple, compact conformation, processing technology is ripe, and convenient to operation, reliability is high, the Naked eye grating TFT LCD that 3D display effect is good.
The utility model realizes like this, a kind of 3D TFT LCD, comprise the raster pattern 3D liquid crystal display be cascading from top to bottom, optical cement layer and TFT liquid crystal display, raster pattern 3D liquid crystal display comprises the upper optical glass be cascading from top to bottom, middle liquid crystal and surrounding frame glue-line, lower optical glass and the FPC connected, TFT LCD is by upper polaroid, upper color filter plate substrate, middle TFT liquid crystal and surrounding frame glue-line, lower TFT substrate, lower polaroid, TFT DRIVER IC, FPC and backlight composition; It is characterized in that: upper polaroid and color filter plate substrate and lower polaroid and lower TFT substrate use pressure sensitive adhesive to bond, TFT DRIVER IC uses ACF (different square conducting resinl) first to be pre-fixed by IC in lower array substrate D RIVER IC Bang Ding district, after carrying out heating pressurization through using COG machine, nation is connected to together surely, TFT FPC uses ACF (different square conducting resinl) by FPC and lower array base palte FPC place, and after using TAB board to carry out heating pressurization, nation is linked together surely.Backlight uses one deck black and white double faced adhesive tape (or black double faced adhesive tape) of its inner glass groove upper surface to cling lower polaroid surface, and then TFT LCD is assembled into glass guide channel in backlight and forms an overall TFT LCD module.
Concrete, described upper and lower optical glass is TN type, and thickness is 0.2mm, 0.3mm, 0.4mm, 0.55mm, 0.7mm equal-specification, and type of drive is generally 1/2 DUTY, 1/2 BIAS, and driving voltage is 1.2 ~ 3.3V.
Concrete, described optical cement layer is the optical cement that applicable GLASS+GLASS fits, and thickness is generally 0.05mm ~ 0.250mm.
Technique effect of the present utility model is: it is simple that (1) 3 D TFT LCD has principle, compact conformation, and processing technology is ripe, and convenient to operation, reliability is high, the good advantage of 3D display effect; (2) TFT LCD module has that structure is simple, lightweight, thickness is thin, product integrated level is high, shock-resistant, vibration resistance, penetrability are high, Glassless 3D, the advantage that manufacturing procedure is few.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of 3D TFT LCD that the utility model embodiment provides, be specially: 3D liquid crystal display comprises the raster pattern 3D liquid crystal display (1) be cascading from top to bottom, optical cement layer (2) and TFT liquid crystal display (3), raster pattern 3D liquid crystal display (1) comprises the upper optical glass (11) be cascading from top to bottom, middle liquid crystal and surrounding frame glue-line (12), lower optical glass (13) and the FPC (14) connected are formed, TFT LCD (3) is by upper polaroid (31), upper color filter plate substrate (32), middle TFT liquid crystal and surrounding frame glue-line (33), lower TFT substrate (34), lower polaroid (35), TFT DRIVER IC(36), FPC(37) and backlight (38) composition, upper polaroid (31) uses pressure sensitive adhesive to bond with color filter plate substrate (32) and lower polaroid (35) with lower TFT substrate (34), TFT DRIVER IC(36) be use ACF (different square conducting resinl) first to be pre-fixed by IC in lower array substrate D RIVER IC Bang Ding district, after carrying out heating pressurization through using COG machine, nation is connected to together surely, TFT FPC(37) be use ACF (different square conducting resinl) by FPC and lower array base palte FPC place, after using TAB board to carry out heating pressurization, nation is linked together surely, backlight (38) uses one deck black and white double faced adhesive tape (or black double faced adhesive tape) of its inner glass groove upper surface to cling lower polaroid surface, and then TFT LCD is assembled into glass guide channel in backlight and forms an overall TFT LCD module.
Upper filter glass, lower array glass, and the pass between the liquid crystal of upper lower-glass and centre is: be first coating polyimide film (PI) by friction process respectively on upper and lower base plate surface, being formed can the alignment films that arranges on request of inducing molecule.The good sealant material of array base palte periphery cloth under TFT afterwards, then by bonding for two pieces of substrate contrapositions, makes CF pattern and TFT pattern of pixels align one by one, then through thermal treatment, encapsulant is solidified.When printing and sealing material, inlet need be left, to vacuumize perfusion liquid crystal.In recent years, along with continuing to increase of technical progress and substrate size, the perfusion that vacuumizes before is also become liquid crystal and drips method in advance by the manufacture technology of liquid crystal cell gradually, liquid crystal drips in advance and generally refers in the envelope frame of CF substrate with multiple Glue dripping head quantitatively large density ground liquid crystal that drips, then utilize the surface tension stream of liquid crystal to make to be full of liquid crystal in viewing area, more under vacuum TFT substrate overturn contraposition, paste box compression heat sealing form liquid crystal cell on CF substrate.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
