Embodiment
Refer to Fig. 2, Figure 2 shows that the schematic diagram of the first embodiment of touch control display apparatus of the prior art.The invention provides a kind of touch-control display module 10, comprise display panels 12, touch-control sensing layer 13, line layer 14 and overlayer 20.Display panels 12 has viewing area BB and neighboring area AA, and display panels 12 has first substrate 16 stacked successively, second substrate 18 and the second polaroid 19.Wherein first substrate 16 is colored filter substrate, and second substrate 18 is thin-film transistor array base-plate.Also accompany liquid crystal layer 17 between certain first substrate 16 and second substrate 18, this is prior art, at this not at detailed description.Touch-control sensing layer 13 is arranged in the viewing area BB of display panels 12.Line layer 14 is electrically connected at touch-control sensing layer 13, and line layer 14 is arranged on first substrate 16, and line layer 14 is positioned at neighboring area AA.Here line layer 14 is driving layer, and namely touch-control sensing layer 13 and line layer 14 represent two electrode layers of electric capacity.Wherein, the material of line layer 14 is such as metal (such as chromium, aluminium, copper, molybdenum, molybdenum aluminium alloy, titanium, titanium-aluminium alloy, silver, silver palladium alloy or aforementioned combination).
And overlayer 20 is covered in make line layer 14 invisible on line layer 14, and the first end 201 closing on the first side 161 of first substrate 16 of overlayer 20 and first substrate 16 close contact.In addition, in present embodiment, overlayer 20 is the first polaroid, and the first polaroid 20 is arranged on first substrate 16, and is positioned at the side of first substrate 16 away from second substrate 18.
And due to line layer 14 overlapping with overlayer 20, therefore not easily discover in appearance and line layer 14.And due to the neighboring area BB of display panels 12 be non-induction zone or non-visible area, therefore overlayer 20 is when the edge of corresponding second substrate 18 is formed, and does not affect inducing function in viewing area or induction region or picture display.
So, use such overlayer 20 make the transmission quality of the contact panel of touch-control display module good and can effectively cover line layer and meet the demand of user to product appearance.
In addition, the thickness of overlayer 20 is preferably 2 μm ~ 10 μm, so can reach desirable screening polarimetry nature.Tectal material comprises lighttight insulating material, such as resin, and resin can be resin or the white resin of black.Preferably, tectal color adopts black.In another embodiment, overlayer is such as refractory ceramics ink; Or this overlayer is utilize gold-tinted processing procedure to be made with photoresist, in order to possess desirable screening polarimetry nature, photoresist can be generally black or white, so that is, overlayer, based on its material characteristic and production method, can have suitable thickness and required screening polarimetry nature.
Refer to Fig. 3, Figure 3 shows that the schematic diagram of the second embodiment according to touch-control display module of the present invention.Be with the first embodiment difference, the overlayer 40 in present embodiment is not the first polaroid.In present embodiment, same, display panels 12 also comprises the first polaroid 15, first polaroid 15 is arranged on first substrate 16, and be positioned at the side of first substrate 16 away from second substrate 18, line layer 14 between the first polaroid 15 and first substrate 16, but in addition, touch-control display module also includes overlayer 40, and overlayer 40 is arranged between the first polaroid 15 and first substrate 16.
In addition, in present embodiment, touch-control sensing layer 13 is also between first substrate 15 and the first polaroid 16, and the touch-control display module in present embodiment is the on-cell touch-control display module often said.
And, continue see Fig. 3, preferably, the first end 401 of overlayer 40 flushes with the first side 161 of first substrate 16, second end 402 of overlayer 40 flushes with one end of first side 161 away from first substrate 16 of line layer 14, wherein, the first end 401 of overlayer 40 is tectal outer end here, and the second end 402 of overlayer 40 is tectal the inner.So, can ensure that the end 141 of line layer 14 can not be outside exposed well, thus also can not go wrong because of the exposed display panels 12 that causes of line layer 14 or cause hydraulic performance decline.
Refer to Fig. 4, Figure 4 shows that the schematic diagram of the 3rd embodiment according to touch-control display module of the present invention.It is similar that touch-control display module in present embodiment and the touch-control in the second embodiment show module, and difference is that the touch-control sensing layer 13 in present embodiment is positioned at the side of first substrate 16 away from the first polaroid 15.Touch-control display module in present embodiment is the In-cell touch-control display module often said.
In sum, for touch-control display module of the present invention utilizes overlayer to cover the line layer of neighboring area completely, make it not expose, thus it is abnormal to avoid display panels to occur.And the overlayer in the present invention also can adopt atrament to be formed, so more by controlling tectal position and width, to cover the line layer of neighboring area completely, and then avoid user from the perimeter circuit can perceiving neighboring area in appearance, thus touch-control is caused to show the apparent defect of module and unsightly.
By the above detailed description of preferred embodiments, be wish clearly to describe feature of the present invention and spirit, and not with above-mentioned disclosed preferred embodiment, protection scope of the present invention limited.Therefore, the protection domain of the claim that the present invention applies for should do the broadest explanation, with the arrangement causing it to contain all possible change and tool equality according to above-mentioned explanation.
