Special one carry be, shading strip 340 and the second bridging line B2 can utilize same processing procedure to form, and therefore the second bridging line B2 is identical with the material of shading strip 340, thus, can in the situation that do not increase existing processing procedure number, form the second bridging line B2 and shading strip 340 simultaneously.In other words, the first insulation course 330, except making the first bridging line B1 and the second bridging line B2 be electrically insulated, also can make shading strip 340 be electrically insulated with corresponding touch control electrode layer 320.
Specifically, referring to Fig. 3 and Fig. 6, shading strip 340 is the tops that are positioned at the light-shielding pattern 314 of arranging along first direction D1 of shielding pattern layer 310, and in other words, the light-shielding pattern extended along second direction D2 314 of the corresponding shielding pattern layer 310 of shading strip 340 arranges.In addition, shading strip 340 corresponding units zones 312 and separated from one another the setting.Furthermore, 340 of shading strips are arranged on the top of the light-shielding pattern 314 of arranging along first direction D1, and be not arranged on along the top of the light-shielding pattern 316 of second direction D2 arrangement, this measure can reduce the stray capacitance between shading strip 340 and touch control electrode layer 322.From another angle, the set position of shading strip 340 is spatially overlapping with data line 130.Yet the person with usual knowledge in their respective areas should be understood that shading strip 340 and data line 130 can be fully overlapping or partly overlap.
In addition, please again simultaneously with reference to Fig. 1 and Fig. 6, shading strip 340 is that correspondence is arranged on adjacent color filter patterns 350(associated description and will illustrates below) second direction D2 on border on, therefore there is the function similar to shielding pattern layer 310, that is effectively cover the ninsolid color light produced by adjacent color filter patterns 350.In this manual, term " ninsolid color light " means the light of non-redness, non-blueness and non-green.
It should be noted that, as shown in Figure 1, if shielding pattern layer 310 and color filter patterns 350(associated description will illustrate below) between have the first insulation course 330, the user is when side direction is visual, the emitted ninsolid color light of touch-control display panel 10 can't be covered by shielding pattern layer 310, therefore cause the problem that display quality is deteriorated.In the present embodiment, because color filter patterns 350(associated description will illustrate below) directly overlay on shading strip 340, this makes shading strip 340 can cover the ninsolid color light that shielding pattern layer 310 can't be covered, thereby, when user's side direction is visual, touch-control display panel 10 still has good display quality.
In addition, in the present embodiment, the width W 4 of shading strip 340 is for example to be greater than 4 microns.In other words, the width W 4 of shading strip 340 need to satisfied be less than the live width W1 of shielding pattern layer 310 and be greater than 4 microns.Yet the present invention not take 4 microns as restriction.Under field have and usually know that the knowledgeable should be understood that and depend in fact the processing procedure limit and process variation, range of size meeting of the width W 4 of shading strip 340 thereby change.In addition, in the present embodiment, because the first touch-control electrode P1, the second touch-control electrode P2 and the first bridging line B1 reticulate structure, the width W 4 of shading strip 340 can be equal to or greater than cancellated live width W2.
In addition, although illustrate shading strip 340 in Fig. 6, be to arrange with the corresponding shielding pattern layer 310 of regular mode, the present invention is not as limit.In other embodiments, shading strip 340 can also be random or the corresponding shielding pattern layer 310 of the mode that any one is regular and arranging.For example, in Fig. 1, although illustrate the touch-control display panel 10 of part, be provided with three shading strips 340, yet according to different set-up modes, can two or or all setting wherein only is set.Therefore, affiliated field has and usually knows that the knowledgeable can adjust according to actual demand the position of shading strip 340.
In this, in order more to clearly demonstrate the relation of corresponding configuration between shielding pattern layer 310, touch control component layer 320 and shading strip 340, please refer to Fig. 7.
In Fig. 7, the corresponding shielding pattern layer 310 of the reticulate texture of touch control component layer 320 arranges, and the light-shielding pattern 314 that shading strip 340 is only arranged along first direction D1 in corresponding shielding pattern layer 310 arranges.What deserves to be explained is, the person with usual knowledge in their respective areas should understand with the description of shading strip 340 for shielding pattern layer 310, touch control component layer 320 by above-mentioned, touch control component layer 320 in Fig. 7 can be the part (that is, the part of the first touch-control electrode P1, the second touch-control electrode P2 or the first bridging line B1) of touch control electrode layer 322.In addition, for clear, illustrate the configuration relation between shielding pattern layer 310, touch control component layer 320 and shading strip 340, in Fig. 7, omit and illustrate the first insulation course 330.
Please, referring again to Fig. 1, a plurality of color filter patterns 350 corresponding unit zones 312 arrange, and cover the second bridging line B2 and shading strip 340.Color filter patterns 350 comprises red filter pattern, green filter pattern or blue filter pattern.
Please refer to Fig. 1, counter electrode 360 is positioned on color filter patterns 350.The material of counter electrode 360 comprises indium tin oxide, indium-zinc oxide, aluminium zinc oxide etc., with and composition thereof or lamination.
