In the present embodiment, the first touch control electrode P1, the second touch control electrode P2 and the first bridging line B1 are made up of reticulate texture, and this reticulate texture is corresponding with shielding pattern layer 310 arranges.Specifically, the one of each opening H1 in the first touch control electrode P1, the second touch control electrode P2 and the first bridging line B1 respectively in corresponding multiple unit area 312.More specifically, each opening H1 in the first touch control electrode P1, the second touch control electrode P2 and the first bridging line B1 is overlapping with the one in multiple unit area 312 respectively.In addition, described cancellated live width W2 is less than the live width W1 of shielding pattern layer 310.Therefore, even if the material of touch control electrode layer 322 is the metals with shading character, the brightness that touch-control display panel 10 can remain certain is still made.
Except above-mentioned touch control electrode layer 322, touch element layer 320 also comprises multiple second bridging line B2.
Referring to Fig. 1 and Fig. 5, the second bridging line B2 is positioned on subtend substrate 300, and the second bridging line B2 is electrically connected in order to make the second touch control electrode P2.The material of the second bridging line B2 can be identical with the material of touch control electrode layer 322, such as, be metal, transparent conductive material or other conductive materials be applicable to.
Furthermore, second touch-control tandem L2 comprises multiple second touch control electrode P2 and multiple second bridging line B2, multiple second touch-control tandem L2 citing is set parallel to each other and is not electrically connected, wherein the second bridging line B2 connects adjacent two the second touch control electrode P2 and the second touch-control tandem L2 is extended along first direction D1, and multiple second touch-control tandem L2 arranges along second direction D2.In addition, in Figure 5, identical with the first touch control electrode P1, the second touch control electrode P2 and the first bridging line B1, the second bridging line B2 is made up of reticulate texture, and this reticulate texture is corresponding with shielding pattern layer 310 arranges.Therefore, each opening H2 in the second bridging line B2 similarly distinguishes the one in corresponding multiple unit area 312.More specifically, each opening H2 in the second bridging line B2 is overlapping with the one in multiple unit area 312 respectively.In the present embodiment, the cancellated live width W3 of the second bridging line B2 is identical with the cancellated live width W2 of the first touch control electrode P1, the second touch control electrode P2 and the first bridging line B1 in fact, therefore, even if the material of the second bridging line B2 is the metal with shading character, touch-control display panel 10 similarly still can maintain certain brightness.
Please referring again to Fig. 1, the first insulation course 330 between touch control electrode layer 322 and multiple second bridging line B2, and covers touch control electrode layer 322.First insulation course 330 is electrically insulated in order to make the first bridging line B1 and the second bridging line B2.The material of the first insulation course 330 is such as inorganic material, organic material or above-mentioned combination, and wherein inorganic material is such as the stack layer of monox, silicon nitride, silicon oxynitride, sieve and silica-sesquioxide or above-mentioned at least two kinds of materials.But the present invention is not as limit, and every material of insulation characterisitic that can provide all optionally is applied to the first insulation course 330 of the present invention.
Referring to Fig. 1 and Fig. 6, multiple shading strip 340 is positioned on the first insulation course 330, and wherein the corresponding shielding pattern layer of shading strip 340 310 arranges and is in electrical floating state, and the width W 4 of shading strip 340 is less than the live width W1 of shielding pattern layer 310.In the present embodiment, the material of shading strip 340 comprises the material with shading characteristic, such as, be metal, metal oxide, metal nitride or other suitable materials.Metal is such as aluminium, copper, silver, gold, titanium, molybdenum, tungsten, chromium, palladium, neodymium, tantalum, niobium etc., and its alloy or lamination.
Special one carry be, shading strip 340 and the second bridging line B2 can utilize same processing procedure to be formed, and therefore the second bridging line B2 is identical with the material of shading strip 340, thus, when not increasing existing processing procedure number, the second bridging line B2 and shading strip 340 can be formed simultaneously.In other words, the first insulation course 330 is electrically insulated except making the first bridging line B1 and the second bridging line B2, and shading strip 340 also can be made to be electrically insulated with corresponding touch control electrode layer 320.
Specifically, referring to Fig. 3 and Fig. 6, shading strip 340 is the tops of the light-shielding pattern 314 along first direction D1 arrangement being positioned at shielding pattern layer 310, and in other words, the light-shielding pattern 314 along second direction D2 extension of the corresponding shielding pattern layer 310 of shading strip 340 is arranged.In addition, shading strip 340 corresponding unit region 312 and arranging separated from one anotherly.Furthermore, shading strip 340 is only arranged on the top of the light-shielding pattern 314 arranged along first direction D1, and not being arranged on the top of the light-shielding pattern 316 along 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 position set by shading strip 340 is spatially overlapping with data line 130.But person with usual knowledge in their respective areas should be understood that shading strip 340 and data line 130 can be completely 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 pattern 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 pattern 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, user is when side direction is visual, ninsolid color light emitted by touch-control display panel 10 cannot be blocked patterned layer 310 and cover, therefore causes the problem of display quality deterioration.In the present embodiment, because color filter patterns 350(associated description will illustrate below) directly overlay on shading strip 340, this ninsolid color light making shading strip 340 can cover shielding pattern layer 310 cannot to cover, thus, 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 such as be greater than 4 microns.In other words, width W 4 demand fulfillment of shading strip 340 is less than the live width W1 of shielding pattern layer 310 and is greater than 4 microns.But, the present invention not with 4 microns for restriction.Belonging to field have and usually know that the knowledgeable should be understood that and depend in fact process margins and process variation, thus the range of size of the width W 4 of shading strip 340 can 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.
