Description

Pressure sensing module with multi-chamber structure

The invention relates to a pressure sensing module, in particular to a flat pressure based on air pressure detecting technology and having multiple air chamber structures inside the module, and can be integrated with a touch panel, a display panel or a touch display panel. Sensing module.

A conventional touch panel is a sensor for detecting a touch and a position thereof, and the touch may come from a finger tip, a stylus tip, a conductor, a non-conductor, etc. The type is usually made into a flat plate shape. According to the working principle of detecting the touch, the capacitive type, the resistive type, the infrared type, and the acoustic wave type are roughly classified, and each category is further subdivided, for example, a capacitive touch panel is distinguished. For mutual capacitance, self-contained, etc., the common use of the touch panel is as an input device of the system, and the detected touch is regarded as an input signal or a control command.

Among the above-mentioned types of touch panels, resistive and capacitive touch detection technologies are most widely used. The resistive touch panels detect on and off between two large-area conductive layers. (off), and the linear resistance change in the x direction and the y direction, and sensing the touch itself and calculating the position coordinate of the touch, the capacitive touch panel mainly detects the change of the capacitance between the two conductive glass and the contact To sense the touch itself and calculate its position coordinates, the conventional touch detection technology has evolved from single-point touch detection to multi-touch detection.

On the practical application level, the touch panel is usually integrated with the display screen to form a touch screen. The user can directly interact with the system directly and intuitively with the finger on the content displayed on the touch screen. The process is very human. It's simple, intuitive, and intuitive, so touch screens have been used in a variety of devices, such as: smart phones, tablets, point-of-sale systems (POS), interactive media kiosks, automatic teller machines (ATM) ), cash register (cashier), car traveling system, industrial man-machine interface and other devices can see the application of touch screen.

On the structural level, the touch screen distinguishes between an out-cell structure, an on-cell structure, an in-cell structure, etc., if the touch panel and the display screen are respective Separately fabricated and assembled together by a bonding technique. Since the touch unit is disposed outside the display cell, the structure is called an "out-cell" structure. If the touch unit is directly fabricated in front of the cell, Or on the back of the conductive glass, this structure is called "on-cell" structure. If the touch unit is directly fabricated between the front and rear conductive glass of the cell, that is, inside the cell, this structure is called "in". -cell" structure.

However, in the conventional technology, whether the touch panel itself or the touch screen integrated with the display screen, the detection capability of the touch is directed to "touch itself and its occurrence position", and belongs to The touch technology implemented on the two-dimensional (2D) plane, these conventional touch detection technologies are completely lacking in the change of the "size" and "time length" of the "force, force" of the touch.

The structure of the gaseous medium 160, the pressure sensor 170, the solid medium 180, the auxiliary structure 190, etc., most of the auxiliary structure 190 is distributed in the solid medium 180, but the auxiliary structure 190 is a selective structure, and may or may not be provided. In this embodiment, an auxiliary structure is selected in the solid medium 180. It is also assumed that a plane parallel to the first substrate 120 or the second substrate 130 is an X plane, and is perpendicular to the first substrate 120 or the second substrate 130. The plane is the Y plane.

The first substrate 120 and the second substrate 130 are preferably rectangular planar substrates, and have appropriate rigidity and slight flexibility or elasticity, and may be selected from a glass substrate, a conductive glass substrate, a conductive substrate or an acrylic substrate. A proper gap is maintained between a substrate 120 and the second substrate 130, and the gap has a gap height H between the gaps between the first substrate 120 and the second substrate 130. The structural wall 140 having the same upper and lower ends respectively contacting the first substrate 120 and the second substrate 130, the wall height and the gap height H being the same, and having a sealing or airtight effect, is preferably disposed in the first embodiment. A gap between the first substrate 120 and the second substrate 130 is surrounded by the four edges of the substrate 120 and the second substrate 130, but the structural wall 140 may be disposed between the first substrate 120 and the second substrate 130. Arbitrarily, and does not need to completely surround all the gaps, it can only partially surround a part of the gap.

The structure of the first substrate 120, the second substrate 130, the structural wall 140, and the like may form a sandwich cavity structure having an airtight effect between the first substrate 120, the second substrate 130, and the structural wall 140, that is, the airtight cavity 150. The airtight chamber 150 includes a gaseous medium 160, a solid medium 180, and an auxiliary structure 190. The airtight chamber 150 can seal the internal gaseous medium 160, the solid medium 180, and the auxiliary structure 190 so as not to leak to the outside, and the airtight portion is airtight. The cavity 150 is preferably a three-dimensional three-dimensional space and has a rectangular shaped airtight cavity.

The outer surface of the first substrate 120 serves as the operation surface 121, and receives the touch input of the conductor, the non-conductor, the contact or the finger. The composition of the gaseous medium 160 preferably includes gas, vapor, atmosphere, nitrogen, oxygen, water vapor, and air. And one of the mixtures thereof, the material of the solid medium 180 is selected from a low molecular weight silicone, an optical elastic film or a soft elastic film, and the auxiliary structure 190 is selected from a solid medium or a high molecular weight silicone, and the structural wall 140 is Made of polyurethane polymer, double-sided tape, epoxy resin, UV-curable adhesive, sealant or combination thereof.

The solid medium 180 is mainly used to conduct the downward pressure generated by the touch to the air chamber 151, and the material thereof is soft or hard, which may affect the user's touch on the module 101. In this embodiment, the solid medium 180 is compared. Preferably, the softer, lower molecular weight tantalum is distributed in a larger area in the gap between the first substrate 120 and the second substrate 130 and in the airtight cavity 150, and is in contact with The first substrate 120 and the second substrate 130, when the solid medium 180 is a soft material, can bring a soft touch to the user, but may absorb the touch force and reduce the touch force to the air chamber 151. s efficiency.

Therefore, by arranging the auxiliary structure 190 in the solid medium 180, the overall softness of the solid medium 180 is adjusted, and the contact force is appropriately guided to the air chamber 151, and the configuration of the auxiliary structure 190 can also amplify the solid medium 180. The local volume change rate at the edge, the transfer efficiency of the solid medium 180 to the force, the edge degumming caused by the overpressure at the edge of the solid medium 180, the blocking of the solid medium 180 into the gas chamber 151, etc., in this embodiment The auxiliary structure 190 is preferably a relatively hard, high molecular weight silicone. The auxiliary structure 190 can be disposed on the first substrate 120 or the second substrate 130. In this embodiment, the auxiliary structure 190 is disposed on the first substrate 120. .

The auxiliary structure 190 is preferably formed in a columnar structure 191 having a columnar shape projected on a Y-plane (as disclosed in FIG. 1), and the columnar structure 191 may be uniformly, non-uniformly, symmetrically in the X-plane. Or asymmetrically distributed in the solid medium 180, the projected shape of the cylindrical structure 191 on the X plane is circular in this embodiment (as disclosed in FIG. 2), but preferably also rectangular, square or other shapes. The auxiliary structure 190 may also form a conical structure projecting a columnar body on the Y plane, and the columnar structure 191 formed thereon has a column height ph of the Y plane between 0 and the gap height H. However, it is preferably about half of the gap height H, but the cylinder height ph is greater than or less than half of the gap height H.

The gas-tight chamber 150 further contains a relatively small amount of gaseous medium 160 inside, and a gas chamber 151 which is also a gas-tight chamber is formed inside the airtight chamber 150. The gas chamber 151 contains a gaseous medium 160, and the gas chamber 151 The range of space covered is the distribution range of the gaseous medium 160, when the gas medium When the mass 160 is affected by temperature or pressure and the volume thereof changes, the volume of the gas chamber 151 also changes accordingly. Four pressure sensors 170 are disposed on the four corners of the gas chamber 151, respectively. The gas pressure and the gas pressure change in the gas chamber 151 are detected, and the number of the pressure sensors 170 is not limited. The pressure sensor is preferably a MEMS (Micro-Electro-Mechanical Systems) pressure micro sensor. In the present embodiment, the airtight chamber 150 contains only a single air chamber 151, which is a single air chamber structure.

When the pressure sensing module 101 of the present invention is in operation, for example, when the user touches the outer surface of the first substrate 120, that is, the operation surface 121 with different degrees of force, or when the touch of the operation surface 121 produces different degrees of force, When mitigating, these different degrees of force touch are transmitted to the gas chamber 151 and the gaseous medium 160 therein through the first substrate 120 and the solid medium 180, so that the volume of the gas chamber 151 and the volume of the gaseous medium 160 in the gas chamber 151 are all generated. Corresponding to the scaling, and corresponding to the rise or decrease of the gas pressure, the pressure sensor 170 in the gas chamber 151 can detect the gas pressure in the gas chamber 151, and the change is caused by different degrees of force touch. The pressure sensing module 101 can sense the strength of the corresponding touch after being converted according to the detected gas pressure change.

3 is a side cross-sectional view showing a pressure sensing module having a single air chamber structure according to the present invention; and FIG. 4 is a schematic top plan view showing a pressure sensing module of the present invention on a MM' section line shown in FIG. 3; For example, the auxiliary structure 190 included in the pressure sensing module 101 of the present invention can be selectively distributed on the outer side of the solid medium 180. For example, in the embodiment, the columnar structure 191 formed by the auxiliary structure 190 is distributed. The solid structure 180, but the peripheral structure 192 formed by the auxiliary structure 190 is distributed outside the solid medium 180, in the chamber 150 near the edge of the solid medium 180, and as close as possible to the edge of the solid medium 180, and the perimeter Structure 192 is preferred The solid medium 180 may or may not be contacted, and in this embodiment, the perimeter structure 192 is in close proximity to the edge of the solid medium 180 but not to the solid medium 180.

In addition to the foregoing single air chamber structure, the pressure sensing module 101 of the present invention can also adopt a multi-chamber structure. For example, when the overall size of the pressure sensing module 101 is large, if the single air chamber structure is maintained, the only air chamber. 151 its volume also increases a lot, but the large air chamber 151 will delay the barometer reaction time, resulting in the module's detection sensitivity and reaction time of the touch force are worse; or when the pressure sensor module 101 overall size is larger At this time, since the transmission efficiency in the airtight chamber 150 decreases with the transmission distance, it is necessary to provide a plurality of air chambers in the airtight chamber 150 so that the touch force can be transmitted to the nearest air chamber. Or when the overall size of the pressure sensing module 101 is large, it is necessary to add a structural wall 140, an auxiliary structure 190 or other supporting structure in the module to maintain the overall strength and rigidity, etc., so it is necessary to be in the airtight cavity 150. A plurality of independent plenums 151 are created to form a multi-chamber structure.

If the pressure sensing module 101 of the present invention is used as an imaginary cut surface at a position about 1/3H away from the first substrate 120, that is, 1/3 of the gap height H, the pressure sensing module 101 is depicted here. The structure of the imaginary cut surface can be obtained as a schematic diagram of the planar structure of the pressure sensing module 101 on the imaginary cut surface, as shown in FIGS. 5 to 15 , which can be used when the pressure sensing module 101 adopts a multi-chamber structure. Various possible implementations.

5 is a schematic plan view showing a planar structure of a pressure sensing module having a multi-chamber structure according to the present invention; FIG. 5 is a view showing a pressure sensing module 101 of the present invention, comprising a second substrate 130, a structural wall 140, and an airtight cavity 150. , gas chambers 151, 152, 153, 154, 155 and 156, gaseous medium 160, pressure sensor 170, solid medium 180, auxiliary structure 190, reaction areas A, B, C, D, E and F, etc. Part of the auxiliary structure 190 is distributed in the solid medium 180, but one part The sub-auxiliary structures 190 are distributed outside of the range beyond the distribution of the solid medium 180.

In this embodiment, the structural wall 140 is disposed at the peripheral edges of the first substrate 120 and the second substrate 130. The upper and lower ends of the structural wall 140 respectively contact the first substrate 120 and the second substrate 130, and surround the first substrate 120 and The peripheral edge of the third substrate 130 forms a single airtight cavity 150 with a gas-tight effect between the first substrate 120, the second substrate 130 and the structural wall 140. The airtight cavity 150 contains a gaseous state inside. The medium 160, the solid medium 180, and the auxiliary structure 190 can seal the internal gaseous medium 160, the solid medium 180, the auxiliary structure 190, and the like so as not to leak to the outside.

The solid medium 180 located in the airtight chamber 150 is distributed from the center to the structural wall 140, close to the structural wall 140 but not to the structural wall 140, leaving a small space between the solid medium 180 and the structural wall 140, the solid medium 180 is filled between the first substrate 120 and the second substrate 130 gap in its distribution range, and contacts the first substrate 120 and the second substrate 130, and a part of the structural wall 140 further extends toward the solid medium 180 until it contacts the solid medium. Thus, the structural wall 140 and the solid medium 180 separate a plurality of mutually independent air chambers 151-156 within the airtight chamber 150.

A gaseous medium 160 is included in each of the gas chambers 151-156. The spatial extent covered by each of the gas chambers 151-156 is the distribution range of the gaseous medium 160. When the gaseous medium 160 is subjected to temperature or pressure, its volume is made. When there is a change, the volume of the air chambers 151-156 will also change correspondingly, so that the air pressure of the air chambers 151-156 is changed. In this embodiment, each of the air chambers 151-156 is provided with a pressure. The sensor 170 can detect the gas pressure and the gas pressure change in the gas chambers 151-156, but the pressure sensor 170 configurable by each of the gas chambers 151-156 is not limited in number.

In the present embodiment, the airtight chamber 150 is roughly divided into six reaction areas AF in the X plane. In general, each of the air chambers 151-156 may correspond to one reaction area AF, or each reaction area AF corresponds to each. Go to a gas chamber 151-156 to touch the touch force in the reaction area in the vicinity. For example, the gas chamber 151 mainly corresponds to the reaction area A, and the touch falls within the reaction area A, and the strength is preferably It is transmitted to the air chamber 151 and its internal pressure sensor 170 in order to detect the touch force quickly and without delay, and the air chamber 152 mainly corresponds to the reaction area B and the like. Under such a structure, when the pressure sensing module When the overall size of the 101 is large, the user's touch can be transmitted to the adjacent air chamber 151 in the area of the six regions, which helps to shorten the reaction time of the pressure sensor 170, reduce the induction delay, and improve Sensing sensitivity.

The auxiliary structure 190 distributed in the solid medium 180, the structure formed on the X plane includes an L-shaped structure 193, a U-shaped structure 194, a horizontal type structure 195, a vertical type structure 196, a straight type structure 198, etc., as in the fifth As shown, for example, the vertical structure 196 auxiliary structure 190 disposed at the center helps to guide the touch force near the center to the nearest central air chamber 152 and the central air chamber 155, which can be improved. The sensing capability of the pressure sensing module 101 in the middle region is similar to that of the tire drainage line, and can be pressed upwards to push the solid medium 180 to deform, resulting in a larger pressure difference, and is disposed at the edge of the solid medium 180. The L-shaped structure 193 assists the structure 190 to amplify the local volume change rate of the solid medium 180 at the edges and to prevent edge degumming of the solid medium 180 at the edges due to overpressure.

Since the pressure sensing module 101 of the present invention is preferably assembled with a touch panel, a display panel or a touch display panel, the distribution range of the solid medium 180 in the airtight cavity 150 of the pressure sensing module 101 is preferably but not limited to Therefore, it should be possible to completely cover (larger than) the touch panel actuation area AA, the display area DS of the display panel, or the display area DS of the touch display panel, and the air chamber 151 and the pressure The position of the force sensor 170 is preferably, but not limited to, the area of the touch panel actuation area AA, the display area DS of the display panel, or the display area DS of the touch display panel.

A slight space is reserved, but a portion of the solid medium 180, that is, the protrusion 181, contacts the structural wall 140, and the solid medium 180 includes the protrusion 181 in the distribution range thereof, and is filled in the gap between the first substrate 120 and the second substrate 130. The first substrate 120 and the second substrate 130 are contacted, and thus the structural wall 140 and the solid medium 180 including the protrusions 181 are separated inside the airtight chamber 150 by a plurality of mutually independent air chambers 151-156.

A gaseous medium 160 is contained in each of the gas chambers 151-156. In the present embodiment, a pressure sensor 171-176 is disposed in each of the gas chambers 151-156, when the gaseous medium 160 is subjected to pressure. When the volume changes, the air pressure of the air chambers 151-156 also changes accordingly, and the pressure sensors 171-176 disposed in each of the air chambers 151-156 can detect the air chambers 151-156 respectively. The internal gas pressure and the gas pressure change.

The airtight chamber 150 is roughly divided into six reaction areas AF in the X plane, and substantially each of the air chambers 151-156 corresponds to one reaction area AF, or each reaction area AF corresponds to one air chamber 151-156, respectively. In order to make the reaction areas AF have a clear boundary with each other, or to make each reaction area AF The reaction states AF can be independently operated and maintained in an isolated state, so that the reaction regions AF do not interfere with each other. In this embodiment, it is preferable that the composite regions belonging to the auxiliary structures 190 are correspondingly arranged at the boundary positions of the respective reaction regions AF. The structure 1912 is used to isolate the reaction area AF. When the overall size of the pressure sensing module 101 is large, the touch of AF in a certain reaction area will be exclusively caused by the pressure sensor of the air chamber of the reaction area. Detection.

The composite structure 1912 is a structure formed by continuous or discontinuous combination of various types of auxiliary structures 190. Both ends of the composite structure 1912 are in contact with the first substrate 120 and the second substrate 130, or only one end is in contact with the first In the present embodiment, the substrate 120 or the second substrate 130 has a relatively large width of the composite structure 1912a at the boundary between the respective reaction regions AF, and both ends thereof are in contact with the first substrate 120 and the first substrate 120 The two substrates 130, but only one end may contact the first substrate 120 or the second substrate 130, and there is no composite structure 1912b having a relatively small width at the boundary between the respective reaction regions AF, and only one end thereof is in contact with The first substrate 120 or the second substrate 130, the composite structure 1912a can clearly define and isolate the reaction region AF.
