According to embodiment of the present utility model, there is provided a kind of display device with pressure sensitivity function.The display device bag
Include framework, touching display screen and pressure sensor 15 and printed substrate 17.Pressure sensor 15 is integrated into printed substrate
On 17, and pressure signal is transmitted by printed substrate 17, printed substrate is hardboard.Touching display screen and printed substrate
17 are arranged on framework.For example, touching display screen includes touch-control surface 13 and the back side 14 relative with touch-control surface 13.Touch-control
Surface 13 is that user implements touch control operation, the surface of pressing operation, is generally facing away from framework.The back side 14 is generally located near framework
Side.Pressure sensor 15 is offseted with touching display screen, and the pressure of touch-control surface 13 is applied to sensing.For example, pressure sensing
Device 15 offsets with the back side 14.For example, pressure sensor 15 can be contacted directly with the back side 14, bolster and the back side can also be passed through
14 contacts, as long as pressing can be sensed.
Framework is that pressure sensor 15 provides support, so that when user presses touch-control surface 13, touching display screen
Deformation can be sensed by pressure sensor 15.
Optionally, framework for electronic equipment housing 11 or be separately provided with touching display screen and pressure sensor
The element that 15 structure matches.
The display device of the utility model embodiment, the back side 14 of touching display screen are provided with pressure sensor 15.When with
When family presses touch-control surface 13, pressure sensor 15 can sense the pressure, and give the pressure transmission to corresponding equipment, with reality
Existing pressure sensitivity function.
Further, since printed substrate 17 is hardboard, therefore the space in structural thickness direction can be saved, Stability Analysis of Structures, reduced
Cost.
In addition, the display device structure is simple, high sensitivity.
In addition, the display device can realize underwater pressing operation and press behaviour in the case where non-conductor contacts (such as wearing gloves)
Make.
Fig. 1 is the sectional view according to the display device of one embodiment of the present utility model.
As shown in figure 1, in this example embodiment, framework is the housing 11 of electronic equipment.For example, the watchcase of intelligent watch.Housing
11 are provided with mounting groove.Touching display screen is arranged on mounting groove, and together with enclosing with framework, to be internally formed appearance at them
Receive space.Pressure sensor 15 is arranged in receiving space, and positioned at the bottom of mounting groove.
Preferably, touching display screen is capacitance plate, such as touch control capacitance screen 12.This display screen have be quick on the draw,
The characteristics of being easy to touch control operation.
In one example, display device also includes setting the overleaf rubber cushion 16 between 14 and pressure sensor 15.
In display device installation process, structure tolerance often occurs.For example, the structure tolerance makes pressure sensor 15 not touch
The back side 14 of touch control capacitance screen 12, build-up of pressure sensor 15 can not sense pressure.The setting of rubber cushion 16 causes pressure sensor
15 are in contact by rubber cushion 16 with the back side 14, so as to be compensated to the structure tolerance.By setting rubber cushion 16, assembling is reduced
Difficulty.When pressing touch-control surface 13, touch control capacitance screen 12 can deform upon user.The deformation causes the position of rubber cushion 16 to occur
Change, the change of position is applied on pressure sensor 15, so that pressure sensor 15 can sense user by rubber cushion 16
Pressing operation.
In addition, rubber cushion 16 also acts as the effect of buffering, pressure sensor 15 can be reduced or even avoided by external impacts.
Optionally, rubber cushion 16 is made by rubber or silica gel.For example, user passes through shape the methods of injection, punching press
Into rubber cushion 16.Above-mentioned material wide material sources, cost are low, and service life is grown.Those skilled in the art can be according to actual feelings
Condition selects the elasticity of rubber cushion 16.
In one example, as Figure 2-3, display device also includes the printed substrate being arranged on framework.Pressure
Sensor 15 is set on a printed-wiring board, and transmits pressure signal by printed substrate.In this way, pressure
The transmission of signal can be more accurate.
In addition, user can be directly integrated into pressure sensor 15 on printed substrate, to facilitate pressure sensor 15
With the connection of printed substrate.
Preferably, printed substrate is hardboard, and pressure sensor 15 is integrated on hardboard, is also integrated with hardboard
Process chip for processing pressure signal and/or touching signals.For example, as Figure 2-3, hardboard has stronger structure strong
Degree.Hardboard is arranged on the bottom of mounting groove.Pressure sensor 15, process chip (not shown), which are integrated on hardboard, forms pressure
The hardboard module of force snesor 15.Pressure sensor 15 and process chip are attached by the circuit on hardboard, in order to pressure
The transmission of signal.Touch control capacitance screen 12 is connected with hardboard, in order to which touching signals are transferred into process chip.Pressure sensor
15 hardboard modules have less thickness, have complied with the development trend that electronic equipment is lightening, minimizes.
In addition, hardboard has strong hardness, it can prevent pressure sensor 15 from misplacing and deforming, in such manner, it is possible to ensure pressure
What is sensed is accurate, and the algorithm of process chip can be made simpler.
Process chip receives pressure signal, and corresponding function is realized according to built-in algorithm.For example, display pressure size,
Trigger or close some software, carry out a certain operation etc..
Preferably, the distance at pressure sensor 15 to the edge of touching display screen is more than or equal to 2 millimeters.For example, such as Fig. 2
Shown, the distance at the edge of pressure sensor 15 to touch control capacitance screen 12 is more than or equal to 2 millimeters.In this way, Neng Goubao
The accuracy that pressure sensor 15 senses pressure is demonstrate,proved, and the size will not improve the installation difficulty of pressure sensor 15.
In one example, pressure sensor 15 is multiple to be gathered with forming multipoint pressure.It can carry in this way
The precision of high pressure sensing.
For example, between touching display screen is circle, and multiple pressure sensors 15 are centered on the center of circle of touching display screen
Every equiangularly arranged overleaf 14.As Figure 2-3, pressure sensor 15 is 4, and 90 ° of the interval cloth centered on the center of circle
Put overleaf on 14.This arrangement has the characteristics of pressure-sensing precision is high.
For example, touch control capacitance screen 12 is square, pressure sensor 15 is 4, and is respectively disposed at close to touch-control electricity
Hold the position in 4 corners of screen 12 or be disposed in close to the position at the midpoint on 4 sides of touch control capacitance screen 12.So, together
Sample can accurately sense the pressure from touch-control surface 13.
According to another embodiment of the present utility model, there is provided a kind of electronic equipment.The electronic equipment can be but not
Mobile phone, tablet personal computer, notebook computer, intelligent television etc. are confined to, can also be intelligent watch, Intelligent bracelet, VR equipment etc.
Wearable device.
