Summary of the invention
In view of this, be necessary to provide a kind of electronic installation with touch-screen of different sensitivity.
The present invention provides a kind of Wrist-wearing electronic device; Comprise display screen and touch-screen; The lobed display surface of this display screen; This display surface comprises the first area of protrusion and around the second area of this first area, this touch-screen is fitted on this display surface, and this touch-screen comprises first touch area and second touch area; This first touch area is corresponding with the first area and the second area of this display surface respectively with second touch area, and the sensitivity of this first touch area is greater than the sensitivity of this second touch area.
The present invention also provides a kind of electronic installation with touch-screen; Comprise display screen and touch-screen; This touch-screen is fitted on this display screen, and this touch-screen comprises first touch area and second touch area, and this first touch area has different sensitivity with second touch area.
Touch-screen with electronic installation of touch-screen of the present invention has different sensitivity, can reduce because of the contact area deficiency causes to make this touch-screen can't detect the probability of user's touch.

Embodiment
With reference to figure 1 and Fig. 2, a kind of electronic installation 10 with touch-screen comprises display screen 20 and touch-screen 30, this touch-screen 30 be fitted in this display screen 20 on observer's display surface.This display screen 20 is roughly rectangular-shaped, and its display surface comprises first area 21 that roughly is positioned at the center and the second area 22 that centers on this first area 21.
With reference to figure 3, in this embodiment, this touch-screen 30 is a mutual capacitance type projection touch-screen in the lump, and it comprises along a plurality of first electrodes 31 of directions X extension and a plurality of second electrodes 32 that extend along the Y direction.Identical with existing mutual capacitance type projection touch-screen: this first electrode 31 and second electrode 32 are superimposed upon on the transparent substrate 33 successively, and have separation layer (figure does not show) between the two.This first electrode 31 and second electrode 32 can be made up of transparent ITO (Indium Tin Oxide, tin indium oxide).Usually, this first electrode 31 comprises the wide width part 34 alternately arranged and is connected wide width part wire portion 35 formations.Same, this second electrode 32 comprises that the wide width part of alternately arranging 34 constitutes with wire portion 35.This touch-screen 30 comprises first touch area 36 consistent with first area 21, and second touch area 37 consistent with second area 22.
Near first electrode 31 finger touch can make touch location during to touch-screen 30 and the coupling capacitance between second electrode 32 change, and the controller (not shown) in the electronic installation 10 is confirmed touch location according to the variation of the coupling capacitance that detects.According to disclosed data; The ratio (hereinafter to be referred as signal to noise ratio (S/N ratio)) of first electrode 31 that causes during finger contact touch-screen 30 and the variation of the coupling capacitance between second electrode 32 and ground unrest is the index of the sensitivity of reflection touch-screen 30; If need to improve the sensitivity of touch-screen 30, then need improve the variation of coupling capacitance or reduce noise.The electric capacity that forms between the variation of coupling capacitance and the finger that contacts touch-screen 30 and electrode (first electrode 31 or second electrode 32) is directly proportional.Ground unrest derives from the voltage signal that display screen 20 produces in order to show.Usually, the area of the wide width part 34 of first electrode 31 or second electrode 32 is big more, and then ground unrest is detected more easily, and promptly ground unrest is big more.
In this embodiment; The area of each first electrode 31 in first touch area 36 and the wide width part 34a of second electrode 32 is all less than the area of each wide width part 34 in second touch area 37, so the interior wide width part 34a in first touch area 36 has lower ground unrest with respect to the wide width part 34 of second touch area 37.Simultaneously; Be provided with pseudo electrode 38 around the wide width part 34a in this first touch area 36; Have certain interval between this pseudo electrode 38 and the wide width part 34a, this two roughly constituted with second touch area 37 in the roughly the same shape of wide width part 34, so; In the ground unrest that has reduced by first touch area 36; Also guaranteed that formed electric capacity does not reduce along with the reducing of area of the wide width part 34a in first touch area 36 when finger touch first touch area 36, that is finger touch first touch area and second touch area 37 can form roughly the same electric capacity.Through above-mentioned setting, 36 to the second touch areas 37, first touch area have higher signal to noise ratio (S/N ratio), that is 36 to the second touch areas 37, first touch area have higher sensitivity.
In the lump with reference to figure 4, this touch-screen 30 has remarkable advantages in following state: this electronic installation 10 is Wrist-wearing electronic device, the lobed display surface of its display screen 20a.It is corresponding with the projection of this display surface that this first touch area 36 is set, and other parts with on this display surface that this second touch area 37 is set are corresponding.Because this first touch area 36 has higher sensitivity, can guarantee also to be detected when the user touches this protruding display surface, and can be because of not contacting the touch that deficiency can't detect the user.
