That is to say that over cap 14 of the present invention directly is arranged at this cabling district 1424 on the curved surface, but not avoid the curved surface setting, therefore can improve the surperficial utilization factor of this over cap 14.In addition, under measure-alike situation, the employing curved surface can increase the surface area of this substrate 142, further improves the surperficial utilization factor of this over cap 14.
This display panel 12 can be display panels, (organic light emitting diode, OLED) display panel or other suitable display panels.In the present embodiment, this display panel 12 is display panels.
This substrate 142 adopts transparent materials such as glass, plastics, sapphire to make, and has good physical property, for example high rigidity, resistance to wear etc.In the present embodiment, this substrate 142 adopts glass to make.
This over cap 14 these display panels 12 of sealing play that dustproof, waterproof, shatter-resistant are bumped, effect such as anti-wear.In addition and since with this sensed layer 144 and this at least lead 146 directly be arranged on this substrate 142, this over cap 14 also plays the effect of traditional touch panel.
In order to reach the set purpose of some, for example, in order to enlarge the surface area of this substrate 142 under size constancy even the situation of dwindling, this substrate 142 includes curved surface, and for example, this cabling district 1424 is inner sunken face.In the present embodiment, whole should assembling face 1422 all be curved surface (for example inner sunken face), that is to say that this sensing area 1423 also is curved surface (for example inner sunken face), and this substrate 142 was equivalent to an optical mirror slip.
