背景技术Background technique
触摸屏由于具有易操作性、直观性和灵活性等优点，已成为个人移动通信设备和综合信息终端的主要人机交互媒介。触摸屏为了能够感应触摸操作压力可以看采用增加压力传感器辅助电容触摸屏的方式，即通过电容屏获取触摸操作点数和触摸操作位置，再根据分布于电容屏背面的压力传感器接收到的压力值，计算出各个触摸点对应的触摸操作压力值，实现设备的压力感知。通过额外增加压力传感器的方式，虽然能够实现压力感应功能，但是成本较高，产品的厚度较大。Touch screen has become the main human-computer interaction medium for personal mobile communication devices and comprehensive information terminals due to its advantages of ease of operation, intuition and flexibility. In order to be able to sense the touch operation pressure, the touch screen can use the method of adding a pressure sensor to assist the capacitive touch screen, that is, to obtain the touch operation points and touch operation position through the capacitive screen, and then calculate the pressure value received by the pressure sensor distributed on the back of the capacitive screen. The touch operation pressure value corresponding to each touch point realizes the pressure perception of the device. By adding an additional pressure sensor, although the pressure sensing function can be realized, the cost is high and the thickness of the product is relatively large.

具体实施方式detailed description
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
下面结合附图详细描述根据本发明实施例的压力感应装置。The pressure sensing device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
参照图1至图11所示，根据本发明实施例的压力感应装置100可以包括保护盖板10、电容感应层20和压力感应层30。Referring to FIGS. 1 to 11 , a pressure sensing device 100 according to an embodiment of the present invention may include a protective cover 10 , a capacitive sensing layer 20 and a pressure sensing layer 30 .
具体而言，电容感应层20和压力感应层30均可以设在保护盖板10下方，保护盖板10可以对其他部件起到保护作用，同时人手可以在保护盖板10上触摸。电容感应层20可以用于检测触摸位置信息，即人手在保护盖板10上的触摸位置和触摸时间。压力感应层30可以用于检测触摸压力，即检测人手施加给保护盖板10的垂直于保护盖板10的压力。Specifically, both the capacitive sensing layer 20 and the pressure sensing layer 30 can be disposed under the protective cover 10 , the protective cover 10 can protect other components, and at the same time, human hands can touch the protective cover 10 . The capacitive sensing layer 20 can be used to detect touch position information, that is, the touch position and time of a human hand on the protective cover 10 . The pressure sensing layer 30 can be used to detect touch pressure, that is, to detect the pressure perpendicular to the protective cover 10 applied by the human hand to the protective cover 10 .
压力感应层30可以包括电阻式压敏材料件31和检测电路32，检测电路32具有多个检测电极对33，每个检测电极对33中的两个电极331可以间隔开设在电阻式压敏材料件31上，以检测电阻式压敏材料件31的处于两个电极331之间的部分的电阻。检测电路32内预设有所述电阻与触摸压力的对应关系数据库，检测电路32可以根据所述电阻的变化得到触摸压力的信息。The pressure-sensitive layer 30 may include a resistive pressure-sensitive material piece 31 and a detection circuit 32. The detection circuit 32 has a plurality of detection electrode pairs 33, and two electrodes 331 in each detection electrode pair 33 may be spaced apart on the resistive pressure-sensitive material. 31 to detect the resistance of the portion of the resistive pressure-sensitive material 31 between the two electrodes 331 . The detection circuit 32 is preset with a database corresponding to the resistance and the touch pressure, and the detection circuit 32 can obtain the information of the touch pressure according to the change of the resistance.
当人手向保护盖板10施加压力时，保护盖板10可以将力向下传递，压力感应层30可以接收该压力作用，电阻式压敏材料件31受力可以发生电阻变化，其中，处于两个电极331之间的部分的电阻的变化可以被检测到，检测电路32可以根据所述电阻变化以及对应关系数据库得到触摸压力的信息。When the human hand applies pressure to the protective cover 10, the protective cover 10 can transmit the force downward, the pressure-sensitive layer 30 can receive the pressure, and the resistive pressure-sensitive material 31 can undergo a resistance change under force. The change of the resistance of the part between the electrodes 331 can be detected, and the detection circuit 32 can obtain the information of the touch pressure according to the resistance change and the corresponding relation database.
由此，压力感应层30可以检测施加在压力感应层30所处位置的力的大小信息，通过设置多个检测电极对33可以实现对多个输入对象的压力实现检测和感应；在电容感应层20和压力感应层30同时处于工作状态的情况下，当电容感应层20和压力感应层30均检测到触摸操作事件时，可以利用电容感应层20识别触摸操作位置，利用压力感应层30识别触摸操作压力；当电容感应层20未检测到触摸操作事件而压力感应层30检测到触摸操作事件时，可以利用压力感应层30识别触摸操作位置和触摸操作压力。Thus, the pressure sensing layer 30 can detect the magnitude information of the force applied to the position of the pressure sensing layer 30, and by arranging a plurality of detection electrode pairs 33, the detection and sensing of the pressure of multiple input objects can be realized; in the capacitive sensing layer 20 and the pressure-sensing layer 30 are in the working state at the same time, when both the capacitance-sensing layer 20 and the pressure-sensing layer 30 detect a touch operation event, the capacitance-sensing layer 20 can be used to identify the touch operation position, and the pressure-sensing layer 30 can be used to identify the touch operation position. Operation pressure; when the capacitive sensing layer 20 does not detect a touch operation event but the pressure sensing layer 30 detects a touch operation event, the pressure sensing layer 30 can be used to identify the touch operation position and touch operation pressure.
根据本发明实施例的压力感应装置100，通过在电容式触摸结构中增加含有电阻式压敏材料件31和检测电极对33的压力感应层30，可以以低成本的方式使电容式触摸结构不但能够检测多个输入对象的精确位置，同时能够实现对多个输入对象的压力实现检测和感应，并且产品的厚度较小。According to the pressure-sensing device 100 of the embodiment of the present invention, by adding the pressure-sensing layer 30 containing the resistive pressure-sensitive material 31 and the detection electrode pair 33 in the capacitive touch structure, the capacitive touch structure can be made in a low-cost manner. The precise position of multiple input objects can be detected, and the pressure of multiple input objects can be detected and sensed at the same time, and the thickness of the product is small.
可选地，压力感应层30和电容感应层20的设置位置可以根据需要进行设置。例如，压力感应层30可以位于电容感应层20的上方、下方或内部。即压力感应层30与电容感应层20可以为简单的上下层叠的结构，也可以为内嵌结构，具体采用哪种结构可以根据具体情况进行设置。Optionally, the positions of the pressure sensing layer 30 and the capacitive sensing layer 20 can be set as required. For example, the pressure sensing layer 30 may be located above, below or inside the capacitive sensing layer 20 . That is, the pressure-sensing layer 30 and the capacitance-sensing layer 20 can be a simple stacked structure, or an embedded structure, and the specific structure can be set according to specific situations.
例如，在本发明的一个实施例中，电容感应层20可以包括两层电极层，压力感应层30可以位于两层电极层之间，电容感应层20和压力感应层30可以位于保护盖板10和显示模组110之间。For example, in one embodiment of the present invention, the capacitive sensing layer 20 may include two electrode layers, the pressure sensing layer 30 may be located between the two electrode layers, and the capacitive sensing layer 20 and the pressure sensing layer 30 may be located on the protective cover 10 and the display module 110.
每个检测电极对33中的两个电极331在电阻式压敏材料件31上的设置位置不做限制，只要将两个电极331间隔开即可。可选地，如图1所示，在本发明的一些实施例中，任意一个检测电极对33中的两个电极331均可以设在电阻式压敏材料件31的同一侧，即两个电极331可以均设在电阻式压敏材料件31的上表面或下表面上。由此，不仅方便制造，而且可以实现电阻变化的测量。The position of the two electrodes 331 in each detection electrode pair 33 on the resistive pressure-sensitive material piece 31 is not limited, as long as the two electrodes 331 are spaced apart. Optionally, as shown in FIG. 1, in some embodiments of the present invention, the two electrodes 331 in any one detection electrode pair 33 can be set on the same side of the resistive pressure-sensitive material piece 31, that is, the two electrodes 331 may be provided on the upper surface or the lower surface of the resistive pressure-sensitive material piece 31 . Thereby, not only is the manufacture convenient, but also the measurement of the resistance change can be realized.
可选地，如图2至图6所示，在本发明的另一些实施例中，任意一个检测电极对33中的两个电极331分别可以设在电阻式压敏材料件31的相背的两侧。也就是说，检测电极对33中一个电极331(即上电极331a)设在电阻式压敏电阻材料件31的上表面上，另一个电极331(即下电极331b)设在电阻式压敏材料件31的下表面上。当压力感应层30受压时，电阻式压敏材料31的上表面与下表面之间的电阻会发生更明显的改变。因此，可以根据各个检测电极对33之间的电阻的阻值的变化关系判断按压的位置以及按压时力的大小信息。由此，不仅方便设置，而且检测更容易且准确，检测效果更好。Optionally, as shown in FIGS. 2 to 6 , in some other embodiments of the present invention, the two electrodes 331 in any one detection electrode pair 33 can be respectively arranged on opposite sides of the resistive pressure-sensitive material piece 31 . sides. That is to say, one electrode 331 (that is, the upper electrode 331a) in the detection electrode pair 33 is arranged on the upper surface of the resistive piezoresistive resistance material 31, and the other electrode 331 (that is, the lower electrode 331b) is arranged on the resistive piezoresistive material member 31. On the lower surface of piece 31. When the pressure-sensitive layer 30 is pressed, the resistance between the upper surface and the lower surface of the resistive pressure-sensitive material 31 will change more obviously. Therefore, the position of the press and the magnitude of the force during the press can be judged according to the change relationship of the resistance value of the resistance between each detection electrode pair 33 . Therefore, not only is the setting convenient, but also the detection is easier and more accurate, and the detection effect is better.
参照图1至图6所示，根据本发明的一些实施例，每个电极331分别可以形成为块状或条状，位于电阻式压敏材料件31的同一侧的多个电极331可以呈阵列布置，例如，呈矩阵布置。由此，电极331在电阻式压敏材料件31上分布更均匀适宜，可以实现多个位置处的触摸压力的检测，检测效果更好，而且方便制造。Referring to Figures 1 to 6, according to some embodiments of the present invention, each electrode 331 can be formed in a block shape or a strip shape, and a plurality of electrodes 331 located on the same side of the resistive pressure-sensitive material piece 31 can be in an array The arrangement is, for example, arranged in a matrix. As a result, the electrodes 331 are more evenly and appropriately distributed on the resistive pressure-sensitive material piece 31 , and the detection of touch pressure at multiple positions can be realized, the detection effect is better, and the manufacturing is convenient.
例如，如图1所示，每个检测电极对33中的两个电极331均可以形成为块状，并且均分布在检测电阻式压敏材料件31的同一侧。其中，距离较近的两个电极331可以形成一个检测电极对33，例如，A与A’可以构成一个检测电极对33，B与B’可以构成一个检测电极对33，C与C’也可以构成一个检测电极对33，每个电极对33均可以实现触摸压力的检测。可选地，电极331可以通过蒸镀、喷涂、丝印等方式制作在电阻式压敏材料件31上。For example, as shown in FIG. 1 , the two electrodes 331 in each detection electrode pair 33 may be formed in a block shape and distributed on the same side of the detection resistance pressure-sensitive material piece 31 . Wherein, the two electrodes 331 with a closer distance can form a detection electrode pair 33, for example, A and A' can form a detection electrode pair 33, B and B' can form a detection electrode pair 33, and C and C' can also form a detection electrode pair 33. A detection electrode pair 33 is formed, and each electrode pair 33 can realize the detection of touch pressure. Optionally, the electrode 331 can be fabricated on the resistive pressure-sensitive material piece 31 by means of evaporation, spraying, silk screen printing, and the like.
再例如，如图3所示，任意一个检测电极对33中的两个电极331分别设在电阻式压敏材料件31的相背的两侧，上电极331a设在电阻式压敏材料件31的上表面上，下电极331b设在电阻式压敏材料件31的下表面上。压力感应装置100还可以包括基底层34，基底层34可以设在两个电极331的背向电阻式压敏材料件31的一侧的表面上。也就是说，基底层34可以包括上基底层341和下基底层342，上基底层341设在上电极331a的上表面上，下基底层342设在下电极331b的下表面上。由此，设置有检测电极对33的电阻式压敏材料件31可以夹设在上基底层341和下基底层342之间，压力感应装置100的结构性能更好，进一步保证检测效果。For another example, as shown in Figure 3, two electrodes 331 in any detection electrode pair 33 are respectively arranged on opposite sides of the resistive pressure-sensitive material piece 31, and the upper electrode 331a is arranged on the resistive pressure-sensitive material piece 31. On the upper surface of the upper surface, the lower electrode 331b is provided on the lower surface of the resistive pressure-sensitive material piece 31 . The pressure sensing device 100 may further include a base layer 34 , and the base layer 34 may be disposed on the surface of the two electrodes 331 on the side facing away from the resistive pressure-sensitive material piece 31 . That is, the base layer 34 may include an upper base layer 341 provided on an upper surface of the upper electrode 331 a and a lower base layer 342 provided on a lower surface of the lower electrode 331 b. Thus, the resistive pressure-sensitive material piece 31 provided with the detection electrode pair 33 can be sandwiched between the upper base layer 341 and the lower base layer 342 , the structural performance of the pressure sensing device 100 is better, and the detection effect is further ensured.
可选地，电极331可以通过蒸镀、涂覆、丝印、气相沉积(CVD)等方式制备在基底层34上，形成为块状的电阻式压敏材料件31可以通过涂覆、丝印等方式在带电极图案的基底层34上进行制备。Optionally, the electrode 331 can be prepared on the base layer 34 by evaporation, coating, silk screen, vapor deposition (CVD), etc., and the block-shaped resistive pressure-sensitive material piece 31 can be formed by coating, silk screen, etc. The fabrication is performed on the base layer 34 with the electrode pattern.
在本发明的一些较优选的实施例中，每个检测电极对33中的两个电极331可以设在电阻式压敏材料件31的两侧并且在水平方向上有重叠。也就是说，每个检测电极对33中的一个电极331设在电阻式压敏材料件上侧，另一个电极331设在电阻式压敏材料件31下侧，在竖直方向上向下投影，两个电极331的投影存在重叠区域或交叉区域。或者说，两个电极331在竖直方向上存在正对部分。由此，这两个电极331可以检测电阻式压敏材料件31在竖直方向上的电阻变化，检测效果更好。In some preferred embodiments of the present invention, the two electrodes 331 in each detection electrode pair 33 can be arranged on both sides of the resistive pressure-sensitive material piece 31 and overlap in the horizontal direction. That is to say, one electrode 331 in each detection electrode pair 33 is arranged on the upper side of the resistive pressure-sensitive material piece, and the other electrode 331 is arranged on the lower side of the resistive pressure-sensitive material piece 31, projecting downward in the vertical direction. , the projections of the two electrodes 331 have overlapping regions or intersection regions. In other words, there are facing portions of the two electrodes 331 in the vertical direction. Therefore, the two electrodes 331 can detect the resistance change of the resistive pressure-sensitive material piece 31 in the vertical direction, and the detection effect is better.
进一步地，如图2和图3所示，每个检测电极对33中的两个电极331分别可以形成为延伸方向垂直的条状。也就说，每个检测电极对33中的两个电极331分布在电阻式压敏材料件31的两侧，两个电极331均形成为条状，并且延伸方向呈90度。由此，不仅便于制造，而且两个电极331在水平方向上可以重叠，可以保证较好的检测效果。Further, as shown in FIG. 2 and FIG. 3 , the two electrodes 331 in each detection electrode pair 33 can be formed in strips whose extending direction is perpendicular to each other. That is to say, the two electrodes 331 in each detection electrode pair 33 are distributed on both sides of the resistive pressure-sensitive material piece 31 , and the two electrodes 331 are formed in a strip shape, and the extending direction is 90 degrees. Therefore, not only is it easy to manufacture, but also the two electrodes 331 can overlap in the horizontal direction, which can ensure a better detection effect.
需要说明的是，以上所描述的压力感应层30的结构仅作为示例进行描述，压力感应层30的结构不限于此，压力感应层30根据电极331的形状、分布位置以及排列情况等的组合变化可以形成多种不同的结构，并不限于附图中所示的结构，这对本领域的技术人员来说是可以理解的，并且这些结构也将在本发明的保护范围之内。It should be noted that the structure of the pressure-sensing layer 30 described above is only described as an example, and the structure of the pressure-sensing layer 30 is not limited thereto. Many different structures can be formed, not limited to the structures shown in the drawings, which are understandable to those skilled in the art, and these structures will also fall within the protection scope of the present invention.
另外，对于具有基底层34的结构而言，基底层34上除了设置检测电极对33之外还可以设置电容感应层20的一些结构。例如，如图6所示，电容感应层20可以包括上线电极221和下线电极222，上线电极221可以设在上基底层341的下表面上，下线电极222可以设在下基底层342的上表面上。电容感应层20和压力感应层30可以形成为穿插结构，两个感应层共用基底层34。由此，可以提高空间利用率，降低厚度以及成本。In addition, for the structure with the base layer 34 , in addition to the detection electrode pairs 33 , some structures of the capacitive sensing layer 20 may also be disposed on the base layer 34 . For example, as shown in FIG. 6 , the capacitive sensing layer 20 may include an upper line electrode 221 and a lower line electrode 222, the upper line electrode 221 may be disposed on the lower surface of the upper base layer 341, and the lower line electrode 222 may be disposed on the lower base layer 342. On the surface. The capacitive sensing layer 20 and the pressure sensing layer 30 can be formed as an interspersed structure, and the two sensing layers share the base layer 34 . Thus, the utilization rate of space can be improved, and the thickness and cost can be reduced.
另外，在该结构中，由于压力感应层30的检测电极对33需要直接连接至掺导电粒子的电阻式压敏材料件31的两侧，因此对电容感应层20的上线电极221与下线电极222进行贴合的光学透明胶层(OCA)在电阻式压敏材料件31的位置可以采取挖孔处理，即开设通孔101，如图7所示，以保证检测效果。In addition, in this structure, since the detection electrode pair 33 of the pressure sensing layer 30 needs to be directly connected to both sides of the resistive pressure sensitive material piece 31 doped with conductive particles, the upper line electrode 221 and the lower line electrode of the capacitance sensing layer 20 222 for laminating the optically transparent adhesive layer (OCA) at the position of the resistive pressure-sensitive material 31 can be punched, that is, a through hole 101 is opened, as shown in FIG. 7 , to ensure the detection effect.
可选地，电阻式压敏材料件31可以为量子隧道复合材料。由此，电阻式压敏材料件31的电阻对压力较为敏感，可以较好的实现触摸压力的检测和感应。例如，电阻式压敏材料件31可以为掺导电粒子的压敏复合材料薄膜。再例如，电阻式压敏材料件可以为掺导电粒子的压敏复合材料块。薄膜和块体易于制造和装配，实用性较强。Optionally, the resistive pressure-sensitive material piece 31 may be a quantum tunnel composite material. Therefore, the resistance of the resistive pressure-sensitive material piece 31 is more sensitive to pressure, and the detection and sensing of touch pressure can be better realized. For example, the resistive pressure-sensitive material piece 31 may be a pressure-sensitive composite film doped with conductive particles. For another example, the resistive pressure-sensitive material piece may be a pressure-sensitive composite material piece doped with conductive particles. Thin films and blocks are easy to manufacture and assemble, and have strong practicability.
当掺导电粒子的电阻式压敏材料件31不受压力时，电阻式压敏材料件31中的导电粒子距离较远，电阻式压敏材料件31呈绝缘或高电阻状态；当电阻式压敏材料件31受压力时，电阻式压敏材料件31受压缩，导电粒子之间的距离变短，由于量子隧道效应，电阻式压敏材料件31中导电粒子之间的电子迁移能力增强，从而从宏观上体现为电阻式压敏材料件31的电阻降低；随着电阻式压敏材料件31受压力的增大，电阻会逐渐减小。由此，可以通过对电阻的检测实现对压力的检测。When the resistive pressure-sensitive material piece 31 doped with conductive particles is not under pressure, the conductive particles in the resistive pressure-sensitive material piece 31 are far away, and the resistive pressure-sensitive material piece 31 is in an insulating or high-resistance state; When the sensitive material piece 31 is under pressure, the resistive pressure sensitive material piece 31 is compressed, and the distance between the conductive particles becomes shorter. Due to the quantum tunneling effect, the electron migration ability between the conductive particles in the resistive pressure sensitive material piece 31 is enhanced, Therefore, macroscopically, the resistance of the resistive pressure-sensitive material piece 31 decreases; as the pressure on the resistive pressure-sensitive material piece 31 increases, the resistance will gradually decrease. Thus, the detection of the pressure can be realized through the detection of the resistance.
根据本发明的一些实施例，电阻式压敏材料件31可以包括导电粒子和绝缘基体，导电粒子可以分布在绝缘基体内。由于，电阻式压敏材料件31在未受压时可以保持绝缘或高电阻状态，当电阻式压敏材料件受压时，分布在绝缘基体内的导电粒子之间的间距可以发生变化，从而使电阻式压敏材料件的电阻可以随着压力发生较明显的变化，从而更易于实现对触摸压力的检测。较优选地，导电粒子可以均匀地分布在绝缘基体内，以保证更好的检测效果。According to some embodiments of the present invention, the resistive pressure-sensitive material piece 31 may include conductive particles and an insulating matrix, and the conductive particles may be distributed in the insulating matrix. Because the resistive pressure-sensitive material piece 31 can maintain an insulating or high-resistance state when it is not under pressure, when the resistive pressure-sensitive material piece is pressed, the spacing between the conductive particles distributed in the insulating matrix can change, thereby The resistance of the resistive pressure-sensitive material piece can change significantly with the pressure, so that it is easier to realize the detection of the touch pressure. More preferably, the conductive particles can be evenly distributed in the insulating matrix to ensure better detection effect.
对于导电粒子和绝缘基体的材质不做特殊限制。可选地，导电粒子可以为金属导电粒子、非金属导电粒子或金属氧化物粒子等，导电粒子的粒径可以为10nm-50um。绝缘基体可以为聚酯纤维层、环氧树脂层、聚酯层、有机硅层或橡胶层等。例如，导电粒子可以为镍、银、铜粉或金属合金粒子等金属导电粒子，也可以为碳黑、石墨或导电纳米管等非金属导电粒子，还可以为如氧化铟锡、氧化铟、氧化锡、氧化锌或氧化钛等金属氧化物粒子。There are no special restrictions on the materials of the conductive particles and the insulating matrix. Optionally, the conductive particles may be metal conductive particles, non-metallic conductive particles or metal oxide particles, etc., and the particle size of the conductive particles may be 10nm-50um. The insulating matrix can be a polyester fiber layer, an epoxy resin layer, a polyester layer, a silicone layer or a rubber layer, etc. For example, the conductive particles can be metal conductive particles such as nickel, silver, copper powder or metal alloy particles, and can also be non-metallic conductive particles such as carbon black, graphite or conductive nanotubes, and can also be metal conductive particles such as indium tin oxide, indium oxide, oxide Metal oxide particles such as tin, zinc oxide, or titanium oxide.
可选地，保护盖板10可以为玻璃盖板、塑料盖板、聚甲基丙烯酸甲酯盖板或蓝宝石盖板等。由此，保护盖板10保护性好，而且外观好。保护盖板10具体采用哪种可以根据需要进行设置。例如，在本发明的一些具体示例中，保护盖板10采用强化玻璃盖板。由此，不仅强度较高，不易损坏，保护性能好，而且装饰性好。Optionally, the protective cover 10 may be a glass cover, a plastic cover, a polymethyl methacrylate cover or a sapphire cover or the like. Thus, the protection cover 10 has good protection and good appearance. Which kind of protective cover 10 is used can be set according to needs. For example, in some specific examples of the present invention, the protective cover 10 is a tempered glass cover. Therefore, it not only has high strength, is not easy to be damaged, has good protection performance, but also has good decoration.

Therefore, it is not only convenient to manufacture, not easy to be damaged, but also has good detection effect. Wherein, a pressure-sensing detection chip can be arranged on the flexible circuit board, and the detection result can also be stored in the pressure-sensing detection chip. In addition, the database of the correspondence between the resistance and the touch pressure can also be preset in the pressure-sensing detection chip.
