Moreover, in the above-described embodiment, shown in Figure 1A, be between second substrate 120 and shielding pattern layer 130, to be example with touch control electrode layer 140, but in another embodiment, as shown in Figure 6, in touch-control display panel 100a, touch control electrode layer 140 also can be between second substrate 120 and shielding pattern layer 130.Or in another embodiment, as shown in Figure 7, touch-control display panel 100b more comprises assisting base plate 170, and assisting base plate 170 is positioned on the outside surface 120a of second substrate 120, and touch control electrode layer 140 is positioned on the assisting base plate 170.In other words, touch control electrode layer 140 is built in the display panel (display panel herein just refers to the structure that first substrate 110 and second substrate 120 and display medium between the two 160 are constituted) in can be shown in Figure 1A, or as Fig. 6 and outer being affixed on the display panel shown in Figure 7.In addition, in the above-described embodiment, all be that to be arranged on second substrate 120 with shielding pattern layer 130 be example, but shielding pattern layer 130 also can be arranged on first substrate 110.For instance, as shown in Figure 8, in the touch-control display panel 100c of an embodiment again, shielding pattern layer 130 also can be arranged on first substrate 110, and between active layers 112 and display medium 160.In addition, (do not illustrate) in one embodiment, shielding pattern layer 130 also can by data line DL shown in Figure 1B and sweep trace SL constituted or have other structures or otherwise be disposed at first substrate 110 or second substrate 120 on.
In the above-described embodiment, because all the other members of touch- control display panel 100a, 100b, 100c are all similar to the touch-control display panel 100 described in first embodiment to configuration mode, therefore do not give unnecessary details in this.But special one what carry is that in touch- control display panel 100a, 100b, 100c, the netted touch pad in the touch control electrode layer 140 can be above-mentioned netted touch pad 146～146d or other netted touch pad designed according to this invention.Moreover, because the netted touch pad of touch- control display panel 100a, 100b, 100c is made of above-mentioned trellis pattern, therefore, touch- control display panel 100a, 100b, 100c also have better visual effect, good transmittance and have good sensing sensitivity in operations.
In sum, in the present invention, the trellis pattern that constitutes netted touch pad is designed to have the specific shape and the trellis length of side, and make between the pixel length of side of the base of trellis pattern and pixel cell and have specific angle, interference between netted touch pad and the shielding pattern layer can be reached minimize, and solve folded line and the trellis pattern is problems such as visual visible structure.In addition, because the reticulate texture of netted touch pad for being made of the trellis pattern, therefore netted touch pad has preferable transmittance, less resistance value and preferable sensitivity.Therefore, touch-control display panel of the present invention has better visual effect, and has good sensing sensitivity in operation.
Though the present invention with embodiment openly as above; right its is not in order to limit the present invention; those of ordinary skill under any in the technical field; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when the scope of looking claims protection defines.
