Fig. 3 is the structure and principle of induction schematic diagram for the touch screen that the utility model one embodiment provides.
Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
Due to the prevalence of narrow frame design scheme, lead to the display touch area and casing (such as hand set machine shell) side of touch screen
The distance between edge is increasingly closer, and when mobile phone is held in the hand by user sees information, the tiger's jaw of palm can be covered close to mobile phone edge
The touch screen of a part is covered, is easy to cause wrong report point, edge clicking operation is identified as by mistake.
By taking a display area is 6 cun of mobile phone as an example, length direction needs 24 channels or so (i.e. along mobile phone screen
The transverse electrode of lateral arrangement), shown referring to Fig.1 (as shown in the figure is only the partial region of touch screen), the then unilateral outlet of mobile phone
The space that needs calculates are as follows: 0.2mm*12=0.24mm, along with corresponding spacing, the sides of mobile phone such as safe distance from side need
The space that width W is 2.53mm is wanted to realize that the signal of transverse electrode is drawn.Therefore, the region of this 2.53mm wide belongs to oncontacting
The sense blind area touched.
Referring to (as shown in the figure is only the partial region of touch screen) shown in Fig. 2, when user's finger and palm are on the side of screen
When edge touches, finger and palm are with the interaction area A and interaction face that are formed between the induction pattern of the touch-sensitive area of touch screen
Product B be it is the same, cause induction amount very close in this way, be difficult the finger or hand that differentiation is user from conventional calculatings angle
Palm touch behavior needs normally to report coordinate if it is finger, to carry out forbidding reporting coordinate if it is palm.The prior art
In can not accurately distinguish whether be palm touch behavior, therefore exist wrong report the case where.
Based on this, referring to shown in Fig. 3 (as shown in the figure is only the partial region of touch screen), one of the utility model is specific
