The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
As shown in fig. 1 to 4, the present invention provides a sensing input device based on a capacitive touch input device, which includes a conductive sensing layer, where the conductive sensing layer is provided with a plurality of conductive sensing units arranged in an array along the X, Y direction of the plane of the conductive sensing layer; the conductive sensing units are isolated and insulated from each other; when the conductive sensing layer is connected with the capacitive touch input device, the conductive sensing units are positioned in a projection area right above the corresponding touch sensor units in the capacitive touch input device; the one or more conductive sensing units correspond to the one or more touch sensor units.
The surface of the capacitive touch input device is provided with the conductive sensing layer corresponding to the touch sensor unit, and the conductive sensor corresponding to the touch sensor unit is arranged in the conductive sensing layer, so that a conductive path is formed among the conductive sensing layer, a conductor connected with the conductive sensing layer and the ground or a power ground; after the circuit is formed, the sensing unit in the conductive sensing layer and the touch sensor unit in the capacitive touch input device can generate the sensing capacitor Cf with enough strength, so that the master control system can capture touch action and calculate the position of a touch point, and the use scene of non-finger direct touch is greatly facilitated; in addition, the conductive sensing layer is arranged, so that the surface of the capacitive touch input device can be protected by the protective film, and the original touch display screen is not easy to damage in daily use.
In an alternative embodiment, the area s (usen) of the conductive sensing unit is greater than or equal to the minimum sensing area Smin of the touch sensor unit.
In this embodiment, according to the capacitance decision formula C = ∈ S/4 ∈ kd, the capacitance touch screen can detect capacitance change caused by a human hand, and actually, a finger is used as a conductor electrode having a contact area Sf and forms an inductive capacitance Cf with the capacitance touch sensor electrode, and an equivalent change capacitance that can be detected and amplified by a circuit of a touch processing chip itself is set as Cc; then cf (min) = Cc = epsilon S/4 pi kd; so, when other parameters are unchanged, there is a minimum sensing area that can be detected by the touch sensor unit: smin =4 pi kdcf (min)/epsilon. The reason why the common conductive pen tip cannot operate the capacitive touch screen is that the pen tip area Sp is smaller than Smin, and the effective inductive capacitance Cf cannot be generated. After the conductive sensing layer is introduced, when a conductor with any shape and connected with the ground or a power supply ground touches a certain conductive sensing unit Usen (x, y) of the surface conductive sensing layer, the Usen (x, y) is immediately conducted with the ground and is converted into an electrode. This electrode corresponds to the touch sensor unit Utouch (x, y), forming an inductive capacitance Cf. The minimum effective area is the area S (Usen) of the conductive sensing unit, and as long as S (Usen) is more than or equal to Smin in the early design, Cf is more than or equal to Cf (min), so that the touch recognition circuit is effectively triggered. For simplifying description and understanding, all the parameters are equivalent parameters, and are equivalently converted according to the parameters related to the actual using scene.
In addition, the touch processing chip scans the touch sensing unit, the Cf value at the Utouch (x, y) point of the touch sensing unit enables the chip to detect that the original capacitance Cp changes, and the touch processing chip sends related touch information to the main control system, so that the main control system can effectively identify the input of the system by conductors in any shapes such as pen points and the like, the original circuit and software algorithm of the touch chip do not need to be adjusted, and whether touch action occurs in the Utouch (x, y) of the touch sensing unit can be confirmed by performing related calculation through the original circuit and algorithm. When the structure is continuously operated by fingers without using tools such as a writing pen and the like, the electrodes which generate the induction capacitance in cooperation with the touch sensing unit are changed into the conductive sensing unit Usen (possibly one or a plurality of) by the fingers, and the finger touch operation can be normally recognized by the touch chip because S (Usen) is not less than Smin. The addition of the conductive sensing layer does not affect the use of the original equipment.
In an alternative embodiment, the conductive sensing unit has a length of L1, a width of L2, and a thickness of L3; the distance between adjacent conductive sensing units along the width direction is L4; the distance between adjacent conductive sensing units along the length direction is L5; the touch sensor unit has a length of L6, a width of L7, and a thickness of L8; the distance between adjacent touch sensor cells in the width direction is L9; the distance between adjacent touch sensor cells along the length direction is L10; let Lsx = L1+ L5, Lsy = L2+ L4, Ltx = L6+ L10, Lty = L7+ L9; the following relationship exists between the conductive sensing unit and the touch sensor unit: lsx is less than or equal to 2 x Ltx, and/or Lsy is less than or equal to 2 x Lty, and/or L1 is less than or equal to 2 x Ltx, and/or L2 is less than or equal to 2 x Lty. Preferably, the following relationship exists between the conductive sensing unit and the touch sensor unit: lsx = Ltx and/or Lsy = Lty and/or L1= L6 and/or L2= L7.
In this embodiment, in order to avoid the undesirable phenomena of the point jump and the point report position inaccuracy caused by one conductive sensing unit corresponding to a plurality of touch sensor units, the following relationships exist between the conductive sensing unit and the touch sensor units: lsx is less than or equal to 2 x Ltx, and/or Lsy is less than or equal to 2 x Lty, and/or L1 is less than or equal to 2 x Ltx, and/or L2 is less than or equal to 2 x Lty. Preferably, the area of the conductive sensing unit is equal to that of the touch sensor unit, and a one-to-one mode is adopted, so that the phenomena of generating signals for a plurality of touch sensor units, generating inaccurate jumping points and reporting positions and the like can be effectively avoided. In addition, relevant parameters (such as surface conductive sensing layer substrate material, conductive material of the conductive sensing unit, conductive sheet resistance, conductivity and other relevant parameters influencing performance such as L1/L2/L3/L4/L5/Lsx/Lsy and the like mentioned above) can be adjusted according to specific use scenes and performance requirements,
in an alternative embodiment, the conductive sensing layer is made of a conductive material.
In this embodiment, the conductive sensing layer may be made of any conductive material according to the use requirement, i.e., a transparent conductive film (with a nanometer thickness), such as a conductive film of ITO, nano silver, an organic conductive film, or a non-conductive body or an opaque body. Specifically, the conductive sensing layer can be directly attached to cover plates made of different materials on the surface of the capacitive touch input device by various processes to be integrated with the capacitive touch input device, or can be independently arranged in the form of accessories such as a protective film, a toughened film and the like, and the conductive sensing unit is arranged on various different base materials and then is installed on the surface of the capacitive touch input device for use. The implementation of the present invention is not limited by the specific implementation type and the main control system of the corresponding capacitive touch input device, and any capacitive touch sensing device can be used and considered as the corresponding embodiment (for example, various capacitive touch screen implementation manners such as GG, GF, GFF, Incell, and ocell are all applicable).
In an alternative embodiment, the same effect of the invention can be achieved by increasing the number of conductive sensing layers or by changing the specific shape of the conductive sensing elements and by performing various combinations of the two.
In an alternative embodiment, one side of the conductive sensing layer is connected with the capacitive touch input device, and the other side of the conductive sensing layer is further provided with a anisotropic conductive material layer connected with the conductive sensing unit. The conductive sensing layer may be extended to be connected to the outer surface by the action of the anisotropic conductive material layer.
In an alternative embodiment, the conductive sense cell has a sheet resistance of less than or equal to 10 megaohms.
In this embodiment, since the touch chip itself scans the touch sensing unit at a certain frequency (fscan), the material of the conductive sensing unit constituting the conductive sensing layer is not limited based on the requirement for the corresponding time, and the sheet resistance of the conductive sensing unit is adjusted according to different requirements, but not more than 10 megaohms at most. Preferably, the voltage is not more than 1 megaohm under the conventional condition, and the adverse phenomena of disconnection, no response, missing report points and the like in the practical use are avoided.
In another aspect, the present invention further provides a sensing input method based on a capacitive touch input device, including the following steps:
step S1, connecting a conductive sensing layer on the surface of the capacitive touch input device;
step S2, the conductive sensing unit of the conductive sensing layer senses the touch operation signal of the user;
step S3, the conductive sensing unit of the conductive sensing layer transmits the touch operation signal to the touch sensor unit of the corresponding capacitive touch input device;
in step S4, the main control system of the capacitive touch input device scans the touch sensor unit, checks the signal variation of the touch sensor unit, and transmits the touch operation signal of the user to the main control system, and performs recognition execution through the main control system.
The surface of the capacitive touch input device is provided with the conductive sensing layer corresponding to the touch sensor unit, and the conductive sensor corresponding to the touch sensor unit is arranged in the conductive sensing layer, so that a conductive path is formed among the conductive sensing layer, a conductor connected with the conductive sensing layer and the ground; after the circuit is formed, the sensing unit in the conductive sensing layer and the touch sensor unit in the capacitive touch input device can generate the sensing capacitor Cf with enough strength, so that the master control system can capture touch action and calculate the position of a touch point, and the use scene of non-finger direct touch is greatly facilitated; in addition, the conductive sensing layer is arranged, so that the surface of the capacitive touch input device can be protected by the protective film, and the original touch display screen is not easy to damage in daily use.
In an optional embodiment, the step S2 specifically includes:
when the electric conductor which is in any shape and is connected with the ground or the power supply ground touches the electric conduction sensing layer, the corresponding electric conduction sensing unit is immediately conducted with the ground and is converted into an electrode, so that the touch operation signal of a user is sensed.
In this embodiment, after the conductive sensing layer is introduced, when a conductor with any shape and connected with the ground or a power supply ground touches a certain conductive sensing unit Usen (x, y) of the surface conductive sensing layer, the conductor enables the Usen (x, y) to be immediately conducted with the ground and converted into an electrode; through the relative area of electrically conductive sensing unit and touch sensor unit, can transmit the signal of nib for touch sensor unit after enlargiing, it is simple convenient.
In an optional embodiment, the step S3 specifically includes:
when the conductive sensing units are converted into electrodes, sensing capacitors Cf are formed between the conductive sensing units and corresponding touch sensor units in the capacitive touch input device, so that the capacitors Cp between the touch sensor units are changed, and a touch operation signal is transmitted to the touch sensor units of the corresponding capacitive touch input device; said is a capacitor
(ii) a Where Smin is the minimum sensing area of the touch sensor unit.
In this embodiment, according to the capacitance decision formula C = ∈ S/4 ∈ kd, the capacitance touch screen can detect a capacitance change caused by a human hand, and actually, a finger is used as a conductor electrode having a contact area Sf to form an inductive capacitance Cf with the electrode of the capacitive touch sensor, and an equivalent capacitance that can be detected and amplified by a circuit of the touch processing chip itself is set as Cc; then cf (min) = Cc = epsilon S/4 pi kd; so the minimum sensing area that can be detected by the touch sensor unit when other parameters are unchanged is: smin =4 pi kdcf (min)/epsilon. The reason why the common conductive pen tip cannot operate the capacitive touch screen is that the pen tip area Sp is smaller than Smin, and the effective inductive capacitance Cf cannot be generated. After the conductive sensing layer is introduced, when a conductor with any shape and connected with the ground or a power supply ground touches a certain conductive sensing unit Usen (x, y) of the surface conductive sensing layer, the Usen (x, y) is immediately conducted with the ground and is converted into an electrode. This electrode corresponds to the touch sensor unit Utouch (x, y), forming an inductive capacitance Cf. The minimum effective area is the area S (Usen) of the conductive sensing unit, and as long as S (Usen) is more than or equal to Smin in the early design, Cf is more than or equal to Cf (min), so that the touch recognition circuit is effectively triggered. For simplifying description and understanding, all the parameters are equivalent parameters, and are equivalently converted according to the parameters related to the actual using scene.
In addition, the touch processing chip scans the touch sensing unit, the Cf value at the Utouch (x, y) point of the touch sensing unit enables the chip to detect that the original capacitance Cp changes, and the touch processing chip sends related touch information to the main control system, so that the main control system can effectively identify the input of the system by conductors in any shapes such as pen points and the like, the original circuit and software algorithm of the touch chip do not need to be adjusted, and whether touch action occurs in the Utouch (x, y) of the touch sensing unit can be confirmed by performing related calculation through the original circuit and algorithm. When the structure is continuously operated by fingers without using tools such as a writing pen and the like, the electrodes which generate the induction capacitance in cooperation with the touch sensing unit are changed into the conductive sensing unit Usen (possibly one or a plurality of) by the fingers, and the finger touch operation can be normally recognized by the touch chip because S (Usen) is not less than Smin.
