Embodiment
For making the object of the invention, structure, characteristic and function thereof there are further understanding, cooperate embodiment to specify as follows now.
See also Figure 1A and Figure 1B, Figure 1A and Figure 1B are the synoptic diagram of the electric resistance touch-control panel 1 of one embodiment of the invention.Electric resistance touch-control panel 1 comprises housing 10, touch control film 11 and diaphragm 12.Housing 10 has first strong point 101.Touch control film 11 is arranged in this housing 10, and this touch control film 11 comprises the touch area (frame of broken lines is with interior zone among Figure 1A) with first area, and first outer rim 111 of this first strong point 101 and this touch area is at a distance of first distance L.Diaphragm 12 is arranged on this touch control film 11, and this diaphragm 12 has the second area (area that shade covered among Figure 1A) greater than this first area, and in should the scope of first distance L, has space 120 between this diaphragm 12 and this housing 10.Wherein, first edge part 121 of this diaphragm 12 is contacted with this first strong point 101 with this housing 10.
In one embodiment, housing 10 comprises first supporting surface 102 and second supporting surface, 103, the first strong points 101 are arranged on this first supporting surface 102, and space 120 is arranged between second supporting surface 103 and the diaphragm 12.Need to prove that the present invention is not as limit.In practical application, four edges of diaphragm 12 all exceed this touch area, and preferably, the distance that exceeds should be greater than first distance L.
In practical application, touch control film 11 can comprise conductive layer.Housing 10 can adopt the rigidity foundry goods.Because the electric resistance touch-control principle is those skilled in the art's common technology, and not emphasis of the present invention place, so do not give unnecessary details at this.
In one embodiment, when on this diaphragm 12, exerting pressure F with these first outer rim, 111 corresponding zones, the lower surface of first edge part 121 of diaphragm 12 more closely contacts with housing 10.See also Figure 1B; Notion by mechanics can be known, when using finger or pointer when the A of contact panel 1 point is exerted pressure F, supposes the touch area of A point representative near the edge; The A point will make the diaphragm distortion and trigger the required pressure F of touch control film just big more more near the edge.The present invention is just through prolonging diaphragm on the direction away from touch control film; With first strong point 101 of housing 10 as the fulcrum that contacts with diaphragm first edge part 121; Be equivalent to the fulcrum zone is elongated; Thereby required applied pressure in the time of can reducing the edge touch-control, and then improved the touch-control sensitivity at electric resistance touch-control panel edge.
