Specific embodiment
A kind of pressure touch display panel of the invention and display device are retouched in more detail below with reference to schematic diagram
It states, which show the preferred embodiment of the present invention, it should be appreciated that those skilled in the art can modify described herein hair
It is bright, and still realize advantageous effects of the invention.Therefore, following description should be understood as the wide of those skilled in the art
It is general to know, and it is not intended as limitation of the present invention.
Fig. 1 is the schematic diagram of the pressure sensitive structure of the prior art, in pressure sensitive touch-control design at present, color membrane substrates side
It is provided with first electrode 1, array substrate side is provided with second electrode 2, and first electrode 1 and second electrode 2 form capacitor C.When outer
Boundary's object, for example when finger touching display panel, the touch control electrode of array substrate side detects position of touch.In addition, finger touches
Pressure the box thickness of display panel can be made to change, generate a certain distance deformation.First electrode 1 passes through with second electrode 2
This generates a capacitance variations apart from deformation, and driving circuit detects the size of finger pressure by calculating capacitance variations.But because
It is smaller for the variation of liquid crystal display panel box thickness, and the basic capacitor formed between first electrode 1 and second electrode 2 is relatively small,
It is not easy to detect the variation of box thickness, the precision that will cause pressure-sensing is inadequate.
To solve the above problems, the present invention provides a kind of pressure touch display panel, as shown in Figure 2 and Figure 3, Fig. 2 is this
A kind of floor map for pressure touch display panel that inventive embodiments provide, Fig. 3 are provided in an embodiment of the present invention along Fig. 2
The sectional structure chart of middle cutting line AA '.In a kind of pressure touch display panel that such as Fig. 2 is provided, including first substrate 1 and the
Two substrates 2, first substrate 1 are oppositely arranged with the second substrate 2, and liquid crystal 10 is arranged between first substrate 1 and the second substrate 2.
It is additionally provided with interval body 4 between first substrate 1 and the second substrate 2, is located at first substrate 1 towards on the side of the second substrate 2.
The surface of first substrate 1 and interval body 4 towards the second substrate 2 is provided with first electrode 11, and the second substrate 2 is towards first substrate 1
Surface be provided with second electrode 21.First electrode 11 and second electrode 21 pass through the formation of liquid crystal 10 first capacitor C1.
In addition, pressure touch display panel further includes spacer 5, the setting of spacer 5 second electrode 21 and interval body 4 it
Between, and first electrode 11 is additionally provided between spacer 5 and interval body 4.Specifically, the corresponding place of all interval bodies 4 is
It is provided with spacer 5, i.e., first electrode 11, which tiles, is arranged in the surface of all interval bodies 4, and 4 one end of interval body is provided with the first electricity
The position of pole 11 position corresponding with second electrode 21 is provided with spacer 5.Between first electrode 11 and second electrode 21 pass through
Parting 5 forms the second capacitor C2.
Specifically, interval body 4 includes the first interval body 41 and the second interval body 42, and the first interval body 41 and second is spaced
Body 42 has different height.In the present embodiment, the first interval body 41 is main interval body, i.e. main-PS, the second interval body 42 is
The height of auxiliary interval body, i.e. sub-PS, the first interval body 41 is higher than the second interval body 42, and the first interval body 41 is mainly in display surface
It plays a supportive role in plate.
Specifically, the dielectric constant of spacer 5 is greater than the dielectric constant of liquid crystal 10.Because of capacitance equation C=ε S/d it is found that originally
In embodiment the distance between first electrode 11 and second electrode 21 compared with the prior art in it is much smaller at a distance from two electrodes, because
The first capacitor C1 provided in this present embodiment is larger, has biggish variation range.In addition, because of the permittivity ε of spacer 5
Greater than the dielectric constant of liquid crystal, therefore, the second capacitor C2 is greater than first capacitor C1.In the present embodiment, first capacitor C1 and second
Capacitor C2 has biggish capacitance variations range compared with the prior art, therefore can more precisely detect pressure touch, increases
Strong pressure touch effect.
In the prior art, display panel only forms capacitor between upper and lower base plate, because the capacitor is to box thickness distance change
Induction it is insensitive, therefore pressure detecting precision is lower.In the present embodiment, first by the way that first electrode is arranged on interval body 4
11, first capacitor C1 is formed with the second electrode 21 of 2 side of the second substrate.According to capacitance equation C=ε S/d it is found that because of first electrode
The distance between 11 and second electrode 21 compared with the existing technology for very little, therefore the basic capacitor of first capacitor C1 is relatively
Greatly, range that can be detected is also relatively broad, conducive to the detection of power and the classification of size.
In addition, because the dielectric constant of spacer 5 is greater than the dielectric constant of liquid crystal 10, therefore first electrode 11 and second electrode
The basic capacitor of 21 the second capacitor C2 formed by spacer 5 is bigger relative to first capacitor C1, and detection range is more extensive.
The present embodiment cooperates to detect pressure size by first capacitor C1 and the second capacitor C2 jointly.Meanwhile because of interval body near
Liquid crystal is in null field, therefore the liquid crystal when showing switching at this does not rotate, and will not influence corresponding position
First capacitor C1.The setting of second capacitor C2 substantially increases the pressure-sensing capabilities of display panel.
