Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail.It is understood that herein
Described specific embodiment is used only for explanation this utility model, rather than to restriction of the present utility model.Further need exist for
It is bright, for the ease of description, the part related to this utility model rather than entire infrastructure are illustrate only in accompanying drawing.
When Fig. 1 a are carrying out to a kind of existing touch-control display panel of obtaining of the method full frame pressing test using emulation
The distribution schematic diagram of diverse location deformation differences on two measurement directions.Referring to Fig. 1 a, the touch-control display panel includes showing
Area 11 and the non-display area 12 around viewing area 11.A pressure is provided only with the non-display area 12 of the touch-control display panel
Power inductance bridge 20, in the A of region.It should be noted that in test, selected pressure sensitive electric bridge 20 is used to detect
Pressing position deformation quantity in the first direction and a second direction, and then obtain the pressing position in a first direction and second direction
On deformation quantity difference, finally the mathematic interpolation of the deformation quantity according to the pressing position in the first direction and a second direction obtain
To the size of touch-control pressure.In fig 1 a, the pressure sensitive electric bridge 20 is detected first direction and second direction and X-axis in figure
The angle in direction is 45 degree.Including the curve of a plurality of closing in the viewing area 11.Numerical value on curve shows should in pressing
On curve during any point, the difference of pressing position deformation quantity in the first direction and a second direction.
Referring to Fig. 1 a, by carrying out full frame pressing test to the touch-control display panel after, find to show when pressing the touch-control
In region B in the viewing area 11 of panel during any position, the pressure sensitive electric bridge 20 cannot detect the size of the touch-control pressure.
This is because pressure sensitive electric bridge 20 is to determine touch-control pressure by detecting pressing position deformation differences in different directions
Size.When any position in the B of the region is pressed, the deformation differences in the both direction that the pressure sensitive electric bridge 20 is detected
Very little, even 0, therefore the pressure sensitive electric bridge 20 cannot detect the size of the touch-control pressure in the area.Region B is referred to as
The inspection blind area of the pressure sensitive electric bridge.
Fig. 1 b are that full frame pressing test is carried out to existing another kind of touch-control display panel using what the method for emulation was obtained
When diverse location deformation differences on two measurement directions distribution schematic diagram.It is different compared with pressure sensitive electric bridge in Fig. 1 a
It is 0 ° that part is the angle of X-direction in the first direction that pressure sensitive electric bridge 20 is detected in Fig. 1 b and figure, inductance bridge
The second direction and the angle of X-direction in figure for detecting 20 is 90 °.The pressure sensitive electric bridge 20 is can be found that from Fig. 1 b
Check frequency (i.e. region B) is located at edge of the viewing area 11 near the side of pressure sensitive electric bridge 20.

Part is that the first direction that pressure sensitive electric bridge 20 is detected in Fig. 1 c is 15 ° with the angle of X-direction in figure, feeling of stress
The second direction that electric bridge 20 is detected is answered to be 75 ° with the angle of X-direction in figure.From Fig. 1 c, still can find, for the pressure
Power inductance bridge 20, still suffers from check frequency on touch-control display panel.
In fact, for the arbitrary pressure sensitive electric bridge being arranged on touch-control display panel, on touch-control display panel
There is check frequency.And comparison diagram 1a to Fig. 1 c, can also draw, for being arranged at same position on touch-control display panel
Pressure sensitive electric bridge for, the detection direction of pressure sensitive electric bridge is different, the check frequency position of the pressure sensitive electric bridge and
It is of different sizes.In fact, for the arbitrary pressure sensitive electric bridge being arranged on touch-control display panel, the position of its check frequency and
Size additionally depends on the pressure sensitive electric bridge in touch-control display surface in addition to the detection direction depending on the pressure sensitive electric bridge
Concrete set location in plate.In addition, for arbitrary pressure sensitive electric bridge, the pressure sensitive electric bridge is removed in display floater viewing area
The region checked outside blind area be the detectable area of the pressure sensitive electric bridge.
