Fig. 3 AAA ' lines illustrate depending on the section entered.Contact panel 304 includes a transparent cover plate 300 and a touch-control sensing layer 305.It is real herein
Apply in example, used transparent cover plate 300 is bend in one direction pattern.The visible surface part of transparent cover plate 300 or user touch
Face is a curved surface 302, and the part that transparent cover plate 300 couples touch-control sensing layer 305 is then a plane 303.Wherein, curved surface 302
Be from a y directions symmetry axis 301 to respectively to positive x and negative x-direction bending and its thickness with more remote from a distance from symmetry axis 301 and
Decline, therefore the bend in one direction pattern of meaning, such as its thickness is thicker close to the part of symmetry axis 301 for transparent cover plate 300, and away from right
Claim its thinner thickness of the both sides of transparent cover plate 300 of axle 301, in other words, curved surface 302 is from symmetry axis 301 to transparent cover plate 300
