Description

The capacitance touching control pen

Technical field

The relevant a kind of capacitance touching control pen of the utility model; Especially refer to a kind of pointer that is used in capacitance type touch-control panel; Can make the soft touch control component of pointer when operation, keep due pliability; But still can effectively limit weak deflection, and guaranteeing that associated components under firm winding, has good internal actions air pressure stream way system.

Background technology

Mobile phone and flat computer that the topmost leader of information products Apple Computer was released modern age mostly adopt capacitance type touch-control panel; This type of contact panel is supported multi-point touch and is combined smooth graphical operation interface; Thereby receive consumers in general's welcome and warmly echo, make other relevant manufacturer information products also one after another follow-up adopt this type of capacitance type touch-control panel.

Capacitance type touch-control panel mainly is at the most electrodes of the even cross-distribution of both direction; When capacitance type touch-control panel receives like the extraneous earth conductor touching of the class of people's finger or pointer; Changed by the electrode self-capacitance touched and the mutual capacitance meeting of above-mentioned infall, can obtain required telecommunication reaction according to the position of electrode that changes or infall.The point that therefore, can see through above-mentioned finger electrostatic current or pointer touches detection and calculates position of touch.

The touch control type operation interface is to reach by the graphical operation interface of contact panel binding operation system basically; Operating capacitance touch screen actual flow is very faint through the signal of capacitance type touch-control panel; Under some operating conditions, receive the excessive or finger temperature of finger and other factor affecting easily and produce skew; Can't precisely carry out character calligraph and drawing performance delicately, under these job statuses, use pointer thereby its necessity is arranged.

Be used in a capacitance touching control structure of this type of capacitance touch control screen in early days; Mainly be to contain a preseting length by the made penholder of conductive material in order to conducting user static; The end of this penholder is provided with one basically by the plastics or the made soft touch control component of rubber of electric conductivity; One nib made by metal haply and that be made as straight-tube shape then is arranged in the above-mentioned pen arm end endoporus, and makes its focal length stretch into above-mentioned soft touch control component.Because soft touch control component directly presses with capacitance type touch-control panel and contacts; Its touch-control end can be made as circular-arc to increase contact area and to prevent the panel that weares and teares usually; The nib focal length that is made as straight-tube shape stretches into to be incorporated in the preset endoporus of soft touch control component and can form the clearance space that is not supported than large tracts of land; Cause user's point on capacitance touch control screen to touch or during slippage, surface of contact centre, the circular-arc end of soft touch control component can form the inside weak phenomenon of moderate finite deformation, because the not enough and induction variation of real contact area is caused at the position that subsides; Make accurately computing of position of touch, and produce the problem that induction is insensitive and squint.

To this shortcoming; No. 100217198 " pointer of capacitance touch control screen " patent case of the novel patent of TaiWan, China then provides a kind of structure-improved; Its pen arm end that is included in a pointer is assembled the copper post of a straight-tube shape, and a soft conductive component is located at the tip of the brushstyle of a writing or painting equally as direct touch control component, and it mainly is provided with a nib between above-mentioned copper post and soft conductive component; Said nib is made as triangle taper section basically; Make its inner bottom part that can press against the preset hole of above-mentioned soft conductive component fully, use the supporting construction that forms soft conductive component touch-control end, and can prevent the soft phenomenon of spoiling that the pointer end is caused when reality is used.But this kind pointer structure-improved for forming required supporting role, almost is in tightlock status between the member between each main actuating member, reckons without the internal air pressure currency structure and has influence on the functions of use of pointer; Simultaneously, obviously also desirable not to the utmost on the connection lead structure that comprises main actuating member such as soft conductive component, copper post and nib.
