1A is a schematic exploded view of a pressure sensing module in accordance with a first embodiment of the present invention. 1B is a partial cross-sectional view of a pressure sensing module in accordance with a first embodiment of the present invention. Referring to FIGS. 1A and 1B , the pressure sensing module 100 has an active area A1 and a peripheral area A2 at least partially surrounding the active area A1. The active area A1 is a light-transmissive area, which is, for example, corresponding to a display area of a display module (not shown) to display an image frame. The peripheral area A2 is an area in which a line is provided. In order to prevent the opaque line from affecting the visual effect of the pressure sensing module 100, the peripheral area A2 may be provided with a decorative layer of a light-resistant material (not shown) or by using a housing (not shown) of the display module to shield Light-transmissive line.

The shape of the active area A1 and the peripheral area A2 may vary depending on design requirements. For example, the shape of the active area A1 may be circular (as shown in FIG. 1A), rectangular or other polygonal shape, and the shape of the peripheral area A2 may be a ring shape, such as a circular ring shape, but the invention is not limited thereto.

The pressure sensing module 100 includes a pressure sensing structure 110. The pressure sensing structure 110 is located in the peripheral zone A2 and exposes the active zone A1. The pressure sensing structure 110 includes a first electrode 112, an intermediate layer 114, and a plurality of second electrodes 116. The first electrode 112 at least partially surrounds the active area A1. The second electrode 116 at least partially surrounds the active area A1, and the second electrode 116 overlaps with the first electrode 112. The intermediate layer 114 is located between the first electrode 112 and the second electrode 116.

In the present embodiment, the first electrode 112 is, for example, a ring-shaped electrode. The intermediate layer 114 is located on the first electrode 112 and covers the first electrode 112. The second electrode 116 is located on the intermediate layer 114 and surrounds the active area A1. The second electrode 116 is structurally separated from the first electrode 112 through the intermediate layer 114. The number of the second electrodes 116 is 3, and the second electrodes 116 are, for example, arc-shaped electrodes. However, the number and shape of the second electrodes 116 may be changed according to design requirements. In other embodiments, the intermediate layer may be located at the The second electrode 116 is covered on the second electrode 116, and the first electrode 112 is located on the intermediate layer 114.

Since the peripheral area A2 is usually shielded by the decorative layer or the housing of the display module, the components in the pressure sensing structure 110 disposed in the peripheral area A2 (including the first electrode 112, the intermediate layer 114, and the second electrode 116) The material is not limited to the light transmissive material. In other words, the first electrode 112, the intermediate layer 114, and the second electrode 116 may be made of an opaque material in addition to the light transmissive material. For example, the first electrode 112 and the second electrode 116 may be made of a metal, an alloy, or a single layer or a plurality of layers of conductive structures stacked as described above. Alternatively, the first electrode 112 and the second electrode 116 may be made of a light-transmitting conductive material, such as a metal oxide, but not limited thereto.

The material of the intermediate layer 114 may also be a light transmissive or opaque material. Further, the material of the intermediate layer 114 is, for example, a dielectric material or a piezoresistive material. When the touch object presses the pressure sensing module 100, the distance G between the second electrode 116 and the first electrode 112 changes according to the magnitude of the force (pressure) applied by the touch object to the pressure sensing module 100. . Under the structure of the material of the intermediate layer 114 being a dielectric material, the change of the pitch G causes the capacitance value between the second electrode 116 and the first electrode 112 to change, so that an external control circuit (not shown) can be based on the above capacitance. The variation of the bias value caused by the value variation or the change of the capacitance value or the variation of the current value that can be turned on determines the magnitude of the pressure applied by the touch object to the pressure sensing module 10. According to the parallel plate capacitor formula and the elastic modulus (also known as Young's modulus) formula, the ratio of the capacitance value to the capacitance value is proportional to the force per unit area and inversely proportional to the elastic modulus. . Considering the pressure channel of the general user, the dielectric constant of the intermediate layer 114 of the present embodiment falls within the range of 2 to 4, and the elastic modulus of the intermediate layer 114 falls within the range of 10 ⁴ Pascal to 10 ⁶ Pascal. Therefore, the amount of change in the capacitance value between the second electrode 116 and the first electrode 112 falls within a range of capacitance values that can be read by the control circuit. For example, the intermediate layer 114 may be cured by Optical Clear Adhesive (OCA), but is not limited thereto. On the other hand, under the structure of the material of the intermediate layer 114 being a piezoresistive material, the change of the pitch G causes the resistance value of the intermediate layer 114 to change, so that the external control circuit (not shown) can be mutated according to the above resistance value or The variability of the measurable current value caused by the change in the resistance value determines the relative value of the pressure applied by the touch object to the pressure sensing module 10. In the above, the pressure sensing module 100 can determine the pressure of the pressure sensing module 100 according to the change of the capacitance value or the resistance value caused by the pressure of the intermediate layer 114 of the pressure sensing structure 110, thereby implementing pressure sensing.
