Description
Technical field
The present invention relates to the technical field of display device, more particularly to a kind of touch-control display module and its pressure sensing group
Part.
Background technology
Strain transducer can apply to touch-screen, to realize pressure sensitive function.The inductive material one of strain transducer
As be non-transparent material metal alloy, traditional common line width of metal strain sensor is wider, easily forms vision and visually imitates
Really, therefore the back side of display device can only be assembled in.
However, touch-screen is when bearing user's pressing, strain transducer is as placement location is further away from cover sheet, its shape
Becoming can be slowed down by the flexible membrane layer below cover sheet, influence the sensitivity of strain transducer.
The content of the invention
Based on this, it is necessary in view of the above-mentioned problems, provide one kind can have more highly sensitive touch-control display module and
Its pressure sensor module.
A kind of pressure sensor module of touch-control display module, including：
Substrate layer；And
Strain transducer, the strain transducer is formed on the substrate layer in latticed；The strain transducer
The line width of grid is less than or equal to 6 microns.
The pressure sensor module of above-mentioned touch-control display module, touch-control display module passes through detection when bearing user's pressing
The resistance variations of strain transducer realize the deformation of detection touch-control display module, so as to realize pressure detecting.Strain transducer is got over
Close cover sheet, deformation degree is higher, and sensitivity is higher.Because strain transducer is in latticed, less than or equal to 6 microns
Line width can visually reach transparent effect beyond the scope of eye recognition.Therefore, strain transducer can be arranged on
Closer to cover sheet position, can make touch-control display module have higher pressure detecting sensitivity.
In one of the embodiments, the relative both sides positioned at the substrate layer of the grid of the strain transducer.Press
During strain transducer, simultaneously resistance variations occur for the grid positioned at substrate layer both sides, can further improve the sensitivity of detection.
In one of the embodiments, the resistance positioned at the Partial Mesh of the strain transducer of opposite sides is identical.
It therefore, it can to form symmetrical wheatstone bridge circuitry, and then influence of the temperature to the resistance of strain sensing unit can be solved
Problem.
In one of the embodiments, the Partial Mesh positioned at the strain transducer of the both sides of the substrate layer is formed
Sensitive grid, bearing of trend is consistent.Therefore, pressure detecting is more sensitive, and sensitivity is higher.
In one of the embodiments, the strain transducer is used for the quick of induction pressure by the local grid protocol that disconnects
Feel grid.Therefore, convenient processing, cost is relatively low.
In one of the embodiments, the distance of disconnection is more than or equal to 10 microns.Gap can effectively insulate.
In one of the embodiments, the distance range of disconnection is 10 microns to 30 microns.Therefore, the distance of disconnection can be with
It is smaller so that overall visually indifference, it is advantageously implemented more preferable visual effect.
In one of the embodiments, in addition to vision supplementary structure, the vision supplementary structure is in latticed；It is described to regard
Feel that supplementary structure and the strain transducer are coplanar, the entirety of the strain transducer and vision supplementary structure formation can
Cover the visible area of the touch-control display module.It can thus be avoided vision difference is produced, with preferable visual effect.
In one of the embodiments, the surface of the strain transducer and the vision supplementary structure is in dark color.Avoid
Color is obvious, can improve visual effect.
In one of the embodiments, the electroplating surface of the strain transducer and the vision supplementary structure has dark plating
Layer.Surface is caused in dark color, to be easy to processing by dark coating.
In one of the embodiments, the material of the dark coating is tin-nickel alloy.The Conductivity Ratio of tin-nickel alloy should

One or more in gold, calite and platinum.Above-mentioned material is needed with the characteristics of resistance change is big after deformation, sharp
Use senses change in pressure.
In one of the embodiments, the angular range of the adjacent net ruling of the grid of the strain transducer be 20 ° extremely
70°.In the case of sensitive grid width identical, if angle is less than 20 °, angle is too small, point of the grid on angular bisector direction
Amount is smaller, and resistance is smaller, and the magnitude of current is larger, and the heat of generation is excessive, is unfavorable for radiating, and temperature rise may influence pressure detecting
Accuracy.If angle is more than 70 °, angle is excessive, and component of the grid on angular bisector direction is larger, and resistance is larger, resistance
More high current is smaller, and the heat of generation is fewer, advantageously reduces the influence of temperature, but the driving voltage of the bigger needs of resistance is more
Greatly, energy consumption can be increased.
In one of the embodiments, the length of the component of the grid of the strain transducer in a first direction with second
The scope of the length ratio of the component in direction is 5.7 to 1.4；The first direction prolongs with the sensitive grid of the strain transducer
Stretch direction consistent, the second direction is vertical with the first direction.In the case of sensitive grid width identical, if in first party
To component length with second direction component length ratio be more than 5.7, the component of first direction is excessive, resistance compared with
Small, the magnitude of current is larger, and the heat of generation is excessive, is unfavorable for radiating, and temperature rise may influence the accuracy of pressure detecting.If
The length of the component of first direction and the length ratio of the component in second direction are less than 1.4, and the component of first direction is too small, electricity
Resistance is larger, and resistance gets over that high current is smaller, and the heat of generation is fewer, advantageously reduces the influence of temperature, but resistance is bigger to be needed
Driving voltage it is bigger, energy consumption can be increased.
In one of the embodiments, the line width scope of the grid of the strain transducer is 1 micron to 6 microns；Herein
In the range of line width, the reliability of connection is unaffected.If the line width of grid is less than 1 micron, grid easily breaks, and causes resistance
Change, influences testing result.If the line width of grid is more than 6 microns, visual effect is easily produced.The grid of the strain transducer
Side size range be 200 microns to 800 microns.If the length of side of grid is less than 200 microns, grid is overstocked, influences light transmission.If
The length of side of grid is more than 800 microns, and grid is excessively thin, and resistance is smaller, is precisely controlled because technogenic influence resistance is more difficult, while power consumption
Also it is larger.
A kind of touch-control display module, it is characterised in that shown including cover sheet, touch-control display panel and described touch-control
The pressure sensor module of module；The cover sheet covers the touch-control display panel, and the pressure sensor module is touched with described
