Specific embodiment
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model a part
Embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, fall within the protection scope of the utility model.
As shown in FIG. 1, FIG. 1 is the schematic diagram of the section structure of touch module provided by the utility model embodiment, the touchings
Controlling mould group includes:
Cover board 1, TP sensor layer 2, liquid crystal display layer and the backlight layer set gradually.
Wherein, which generally can be used glass cover-plate or PMMA cover board, but it is not excluded that using the lid of other materials
Plate.
It should be noted that touch module includes three kinds of structures: OGS structure, i.e. one glass solution, monolithic glass
Glass processing procedure directly forms ITO conductive film and sensor structure on a sheet glass；GG structure, glass cover-plate+optical cement+
The touch module of sensor glass；PG structure, PMMA cover board+optical cement+sensor glass touch module.
Touch module in the utility model is primarily referred to as GG structure or PG structure, i.e., above-mentioned cover board 1 is using glass cover
Plate or PMMA cover board.
Optionally, it because touch module requires user hand substantially and gives directions touching, is inevitably stayed in touch-control screen surfaces
Therefore lower fingerprint can be arranged anti-fingerprint coating on the surface of cover board, avoid touch screen fingerprint surface excessive, influence user's
Usage experience.
TP sensor layer 2 includes glass substrate and the ITO conductive layer that glass baseplate surface is arranged in.
Liquid crystal display layer and backlight layer are the LCD assembly and backlight assembly in conventional touching display screen, specifically
Ground, can refer to Fig. 1, and LCD assembly includes the groups such as upper polaroid 31, upper glass plate 32, lower sheet glass 33, down polaroid 34
Part；Backlight assembly includes antireflective coating 41, Diffusion barrier layer 42, light guide plate 43, reflective coating 44 and glue frame 45.
Closed space is collectively formed in glue frame 45 and glass substrate, encapsulates all parts of touch module, and in general, TP
The width dimensions of sensor layer 2 are, the width dimensions of all parts of liquid crystal display layer and the increasing of backlight layer identical with cover board 1
The width dimensions of the components such as light film layer 41, Diffusion barrier layer 42, light guide plate 43, reflective coating 44 are intended to be slightly less than the width of cover board 1
Size is used for encapsulated liquid crystal so general be collectively formed closed space by the glass substrate of glue frame 45 and TP sensor layer 2
Display component and backlight assembly.
Cover board 1 includes sight area and non-line-of-sight area, and sight area needs to illuminate by the light of backlight layer, in order to avoid user
The internal component that touch module can be watched by non-line-of-sight area, bad visual experience is brought to user, in the non-of cover board 1
The first light shield layer 11 can be set in visibility region.
But the sight angle of user is not always the surface perpendicular to the cover board 1 of touch module, when user sight and
Cover board 1 at an angle when, user be still able to by from the side edge of liquid crystal display layer reflect light observe touch-control
The internal part of component.And hence it is also possible to further be provided with the second light shield layer at the surface edge zone of glass substrate
21, wherein the second light shield layer and ito film layer are located at glass substrate two different surfaces up and down.Second shading is set
The surface of layer 21 is the surface that glass substrate is bonded liquid crystal display layer.
Specifically, it can refer to Fig. 2, Fig. 2 is light path schematic diagram in the touch module of not set second light shield layer, void in Fig. 2
It is the region that user's sight is able to observe that when being not provided with the second light shield layer 21 in wire frame, line with the arrow is in dotted line frame
The schematic lines of light reflection.By Fig. 1 it is found that will have the light at partial liquid crystal display layer edge if being not provided with the second light shield layer 21
Line enters in the sight of user.
Further, as shown in Figure 1, the marginal surface of backlight layer fitting liquid crystal display layer is provided with third light shield layer 30,
That is to say that the marginal position of backlight layer to add lustre between film layer 41 and upper polaroid 31 is provided with third light shield layer 30, be conducive into
The light for blocking to one step backlight layer edge-emission also has certain barrier effect to the entire light for touching mould group edge.
By the mating reaction of the first light shield layer 11, the second light shield layer 21 and third light shield layer 30, liquid crystal is blocked
Show that the light of layer edge reflexes in human eye sight, user is made only to be able to observe that the first light shield layer 11 and from marginal position
Two light shield layers 21, improve the visual experience of user.
Optionally, the first light shield layer 11 and the second light shield layer 21 are disposed as black ink layer or black gummed paper layer.Because
Black has the ability of good absorption light, can effectively prevent the transmission of light.
Optionally, which can be shading glue.
In addition, being bonded optical adhesive layer by TP between glass substrate and cover board 1 is bonded to each other connection.And liquid crystal display layer and
It is fitted and connected between glass substrate by being bonded optical cement entirely.
Based on above-mentioned any embodiment, for the glue frame 45 of backlight film layer, it may include annular element 451 and be set to annular
The plate structure 452 of 451 one end of component, liquid crystal display layer and backlight layer are arranged in the inner ring of annular element 451, and plate
Structure 452 and glass substrate are located at the both ends of annular element 451, form enclosure space.Specifically, it can refer to Fig. 3, at this
In the another specific embodiment of invention, may include:
The internal ring wall and antireflective coating 41 of annular element 451, Diffusion barrier layer 42, light guide plate 43, reflective coating 44 edge
It fits, then from the edge-of-parts such as the antireflective coating 41 of backlight layer, Diffusion barrier layer 42, light guide plate 43, reflective coating 44
The light launched, so that it may directly by 51 inner wall of annular element and antireflective coating 41, Diffusion barrier layer 42, light guide plate 43, reflection
In all parts of the direct back into backlight layer in interface between the edge-of-parts such as film layer 44, without by gap between the two
It is reflected to the direction of cover board 1.
The utility model additionally provides a kind of car-mounted display equipment, which includes any embodiment institute as above
