Following embodiment and graphic in, same or analogous label is represented same or analogous assembly, with simplified illustration.
Second embodiment
Fig. 4 is the schematic top plan view of the electric resistance type touch control display panel 700 of second embodiment of the invention.Electric resistance type touch control display panel 700 is similar to electric resistance type touch control display panel 400, and only both main difference parts are: the arrangement mode of zone C and region D is different.As shown in Figure 4, zone C and region D are all along a specific direction, and for example the x direction is arranged in rows, and zone C and region D and present alternately configuration.It should be noted that in the present embodiment though zone C and region D are to be arranged in rows along the x direction, yet in other embodiments, zone C and region D also can be arranged in row along the y direction.
The 3rd embodiment
Fig. 5 is the schematic top plan view of the electric resistance type touch control display panel 800 of third embodiment of the invention.Electric resistance type touch control display panel 800 is similar to electric resistance type touch control display panel 400, and only both main difference parts are: each subpixel area C
1Respectively corresponding contact hole h, and the respectively corresponding contact hole h of each pixel region D.
The 4th embodiment
Fig. 6 is the schematic top plan view of the electric resistance type touch control display panel 900 of fourth embodiment of the invention.Electric resistance type touch control display panel 800 is similar to electric resistance type touch control display panel 400, only both main differences be in: the first touch pad 542a of present embodiment is different with the plan view shape of the plan view shape of the second touch pad 544a and electric resistance type touch control display panel 400.As shown in Figure 6, in the staggered place of the first touch pad 542a and data line 520, the plan view shape of the first touch pad 542a has constriction position (neckig), with the stray capacitance (parasitic capacitance) that reduces by the first touch pad 542a and data line 520.Similarly, in the staggered place of the second touch pad 544a and data line 520, the plan view shape of the second touch pad 544a also has the constriction position, to reduce the stray capacitance of the second touch pad 544a and data line 520.
In sum, the electric resistance type touch control display panel that embodiments of the invention proposed is owing to have a plurality of sub-touch control units, so can increase the sensitivity of electric resistance type touch control display panel, and because the increase of sub-touch control unit number, also make that the touch-control pressure on the electric resistance type touch control display panel can be disperseed, and then prolong the serviceable life of electric resistance type touch control display panel.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; 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 looking accompanying the claim person of defining.
