Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The utility model provides a kind of display device, comprise the array that several drive electrodes and induction electrode form, described drive electrode and induction electrode have identical structure, specifically as shown in Fig. 1～5, this structure comprises: T font electrode body (drive electrode main body 11, induction electrode main body 21) and symmetrical, and connect some electrode support body (drive electrode support bodies 12 of described electrode body, induction electrode support body 22), to form symmetrical the first sub-electrode and second sub-electrode two parts (part as shown in solid box in Fig. 3 and dotted line frame).Induction electrode comprises: the first induction electrode 2 and the second induction electrode 3.Adjacent three drive electrodes are respectively arranged with first induction electrode 2 and the second induction electrode 3 between any two, and the electrode support body of drive electrode is arranged on the gap location of the adjacent electrode support body (the electrode support body of the electrode support body of the first induction electrode 2 or the second induction electrode 3) of the described induction electrode being adjacent, and described the first induction electrode 2 is connected different signal wires separately with the second induction electrode 3.
Particularly, described drive electrode 1 and induction electrode are arranged as follows in a row or column: the electrode support body 11 of the first sub-electrode of arbitrary described drive electrode 1 inserts the gap between the electrode support body 22 of the second sub-electrode of previous the first induction electrode 2 being adjacent, and the electrode support body 11 of the second sub-electrode of described drive electrode 1 inserts the gap between the electrode support body 22 of the first sub-electrode of rear second induction electrode 3 being adjacent.The first induction electrode 2 connects the first induced signal line 2 ＇, and the second induction electrode 3 connects the second induced signal line 3 ＇.Each drive electrode 1 connects a drive electrode signal wire 5 separately.Wherein, shielding earth 4 is for shielding the phase mutual interference between interference and the adjacent sensing unit of outer bound pair electrode signal.
Wherein, electrode support body and electrode body are and are greater than the angle that 0 degree is less than 90 degree.In Fig. 5, the first induction electrode 2 and the second induction electrode 3 are decomposed out signal (so that understanding).Drive electrode 1, the first induction electrode 2 are identical with the shape of the second induction electrode 3 similar " flakes " and shape, and both are staggered forms a basic capacitive sensing unit in conjunction with (outstanding electrode support body inserts in the other side's a body space mutually); The elementary cell of the multiple repetition of whole touch screen induction layer is arranged and is formed, and forms multiple lines and multiple rows.Wherein, the first induced signal line 2 ＇ are around the outline cabling of the second induction electrode 3, the cabling of such the first induced signal line 2 ＇ can be arranged on same layer with the first induction electrode 2, the second induction electrode 3 and the second induced signal line 3 ＇, has avoided again having and intersecting with the second induced signal line 3 ＇ simultaneously.
Owing to comprising two induction electrodes, this " two induction " arrangement mode, i.e. corresponding two induction electrode leading points in same row, a drive electrode forms two basic capacitive sensing unit with " 2 × half induction electrode ".Concrete as in Fig. 2, the latter half (i.e. the second sub-electrode) of the first half of drive electrode 1 (i.e. the first sub-electrode) and the first induction electrode 2 forms a basic capacitive sensing unit.The latter half (i.e. the second sub-electrode) of drive electrode 1 forms another basic capacitive sensing unit with the first half (i.e. the first sub-electrode) of the second induction electrode 3, in the time forming the sensing unit of same number, the number of the drive electrode 1 of Fig. 2 mode is relatively few, and cabling is also relatively few.Therefore, such mode can ensure less electrode separation (being the center distance of elementary cell), (this part cabling region belongs to the inactive area of touch to have reduced again the quantity of drive electrode cabling-" cabling region ", the smaller the better, its size directly affects the linearity of line).
