Embodiment
See also Fig. 2, Fig. 2 is the structural representation of touch-type display 100 of the present invention.The invention provides a kind of available pressure and control the touch-type display 100 of magnification.Touch-type display 100 includes a display panel 104, a sensing face 102, a display controller 106 and a pressure detector 108.Display panel 104 is used for the display image picture.Wherein sensing face 102 forms a touch sensor with pressure detector 108.Sensing face 102 is used for sensing one and puts on the pressure size and location of sensing face 102 external force, and produces corresponding pressure signal and position signalling.Display controller 106 is electrically connected on display panel 104 and this touch sensor, be used for controlling the shown image frame of display panel 104, and according to position signalling that this touch sensor produced, will with the corresponding image frame part of this position signalling, a central processing unit (CPU) 112 and a storer 114 by a personal computer 110, amplified according to a magnification, this magnification is the pressure signal that is produced by this touch sensor, decides according to a predetermined translative mode.
See also Fig. 3, Fig. 3 is the decomposition organigram of touch-type display 100 of the present invention shown in Figure 2.Transparent sensory panel 102 is fixed in the surface of display panel 104.Sensory panel 102 includes a plurality of pressure-sensitive sensing cells 128, and each sensing cell 128 all is positioned at a precalculated position of display panel 104, is used for the pressure size of sensing one external force.As shown in Figure 4, along a direction A, a touch points 122 of light pressure sensitivity drafting board 102 produces this external force by a control pen 120.Pressure detector 108 is electrically connected on sensory panel 102, is used for detecting the pressure size and location of this external force that sensory panel 102 sensed, and produces corresponding pressure signal and position signalling.
The pressure-sensing method of touch-type display 100 of the present invention, for each sensing cell 128 has included an electric capacity 129, and when this external force puts on sensing cell 128, the capacitance of the electric capacity 129 of sensing cell 128 can change, and the capacitance method of measuring electric capacity 129 for those skilled in the art energy unlabored, so do not given unnecessary details at this.Then, pressure detector 108 can produce this pressure signal by the capacitance that detects sensing cell 128, and produces corresponding position signalling 124 by the position 122 at sensing cell 128 places.
See also Fig. 4, Fig. 4 is the pressure survey synoptic diagram of touch-type display 100 of the present invention shown in Figure 3 when touching.When control pen 120 presses the touch points 122 of sensory panel 102, by reason of heavy pressure little difference, control pen 120 distances of being depressed thereby different, sensory panel 102 thickness originally is d, sensory panel 102 is the rubber-like film like plank of a softness, bigger when controlling pen 120 strength that press down, sensory panel 102 remaining thickness d are just little; Opposite, pen 120 strength that press down are littler when controlling, and sensory panel 102 remaining thickness d are just bigger.And the thickness d of the capacitance of electric capacity 129 and sensory panel 102 has following relationship:
Capacitance=∑ A/d
Instantly amount of pressure is bigger, and d is littler, and capacitance is just bigger.
