Embodiment
For technology contents that the application is disclosed is more detailed and complete, can be with reference to accompanying drawing and following various specific embodiments of the present invention, identical mark represents same or analogous assembly in the accompanying drawing.Yet those of ordinary skill in the art should be appreciated that the embodiment that hereinafter provides limits the scope that the present invention is contained.In addition, accompanying drawing only is used for schematically being illustrated, and does not draw according to its life size.
With reference to the accompanying drawings, the embodiment of various aspects of the present invention is described in further detail.
Fig. 1 illustrates touch control display apparatus of the prior art makes the UV adhesive curing between contact panel and the liquid crystal display module by the UV irradiation schematic diagram.
With reference to Fig. 1, this touch control display apparatus comprises a contact panel 1 and a liquid crystal display module 2, wherein, and black matrix 103 and black matrix 105 that contact panel 1 comprises a touch screen 101 and lays respectively at touch screen 101 both sides.Liquid crystal display module 2 has a frame glue 201 and 203, this frame glue 201 and 203 hold respectively liquid crystal display module 2 around.Wherein, the upper surface of frame glue 201 is corresponding with black matrix area 103, and the upper surface of frame glue 203 is corresponding with black matrix area 105.
As previously mentioned, in this touch control display apparatus, for contact panel 1 and liquid crystal display module 2 are sticked together securely, a UV glue-line 3 often is set between contact panel 1 and liquid crystal display module 2, realizes binding function by the curing of this UV glue-line 3.As shown in Figure 1, when the UV of outside light when the top shines touch control display apparatus, this UV light arrives most of zone of UV glue via transparent touch screen 101, and then realizes solidifying.But to arrive the UV glue of its below regional because touch screen 101 both sides are provided with that black matrix 103 and 105, UV light can't penetrate these black matrixes, causes this UV glue zone not to be cured.In case uncured UV glue infilters backlight module, will make backlight module contaminated or damaged.
When the touch control display apparatus that Fig. 2 illustrates Fig. 1 utilizes the UV irradiation of side directions, the schematic diagram of the curing depth of UV glue.
For the problem that above-mentioned Fig. 1 mentions, a solution of the prior art is to be, UV light changes by the side directions irradiation from touch control display apparatus, and then the two side portions of UV glue is further solidified after the vertical direction irradiation.Yet the curing depth of this UV glue (Fig. 2 indicates with d) is still less, approximately between 5mm ~ 10mm, still has suitable UV glue zone not yet to be cured.
For defective or the deficiency of above-mentioned Fig. 1 and Fig. 2, the invention provides the touch control display apparatus structure after a kind of improve.Schematic diagram when particularly, Fig. 3 illustrates touch control display apparatus according to one embodiment of the present invention and utilizes the UV irradiation of side directions.
Be similar to Fig. 1, in Fig. 3, touch control display apparatus of the present invention comprises a contact panel 1 and a liquid crystal display module 2.Wherein, contact panel 1 is positioned at the top of liquid crystal display module 2.Contact panel 1 comprises a touch screen 101 and the black matrix 103 and 105 that is positioned at touch screen 101 both sides.Liquid crystal display module 2 has frame glue 201 and 203.This frame glue 201 and 203 hold liquid crystal display module 2 around, and frame glue 201 is corresponding with black matrix 103 and 105 respectively with 203 separately upper surfaces.UV glue 3 is cured UV glue 3 by the UV irradiation of outside between contact panel 1 and liquid crystal display module 2, to bind contact panel 1 and liquid crystal display module 2.
It needs to be noted, in touch control display apparatus of the present invention, the lower surface of the black matrix 103 of contact panel 1 is provided with one first reflection horizon 107, and the upper surface of the frame glue 201 of liquid crystal display module 2 is provided with one second reflection horizon 205.After UV light is incident to the inside of UV glue 3 from the side directions (as shown by arrows in FIG.) of device, improve the curing depth of UV glue 3 by the first reflection horizon 107 and the second reflection horizon 205.For example, when UV light was advanced in the inside of UV glue, a part of light that arrives the reflecting surface in the first reflection horizon 107 can reflect, and the light after the reflection arrives the reflecting surface in the second reflection horizon 205, and again reflects.And for example, a part of light that arrives the reflecting surface in the second reflection horizon 205 can reflect, and the light after the reflection arrives the reflecting surface in the first reflection horizon 107, and again reflects.From the above, incide the UV light of UV glue inside from side directions, by the Multi reflection between the first reflection horizon 107 and the second reflection horizon 205, so that the travel distance of UV light is longer, thereby can increase significantly the curing depth of UV glue, improve and promote the state of cure of UV glue.
In one embodiment, the first reflection horizon 107 is white reflection material, and the second reflection horizon 205 also is white reflection material.After tested, the curing depth of UV glue 3 can reach 20mm.
In one embodiment, the first reflection horizon 107 is silver color reflection material, and the second reflection horizon 205 also is silver color reflection material.After tested, the curing depth of UV glue 3 also can reach 15mm.
In addition, in order farthest to bring into play the reflection characteristic in reflection horizon, can be with the length in the first reflection horizon 107 length greater than the second reflection horizon 205.More preferably, with the inboard in the first reflection horizon 107 (namely, end near the centre) inboard with black matrix 103 is set on same straight line at vertical direction, and the inboard in the second reflection horizon 205 (that is, near a middle end) inboard with frame glue 201 upper surfaces is set on the same straight line at vertical direction.
Adopt touch control display apparatus of the present invention, lower surface at the black matrix of contact panel arranges the first reflection horizon, and the upper surface at the frame glue of liquid crystal display module arranges the second reflection horizon, after UV light incides UV glue inside, the propagation distance that prolongs UV light by the Multi reflection between this first reflection horizon and the second reflection horizon, and then improve the curing depth of UV glue, make the UV adhesive curing more abundant, so bonding more firm between contact panel and the liquid crystal display module.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, in the situation that without departing from the spirit and scope of the present invention, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replacement all drop in claims limited range of the present invention.
