Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a touch panel, a touch display and a touch-controlled all-in-one machine. Background Art

[0002] As is known, the capacitive touch panels of touch displays in the prior art are divided into self-capacitive touch panels and mutual-capacitive touch panels. The typical defect of the self-capacitive touch panel is that its touch electrode forms a capacitor with the ground. When a finger touches the panel, the capacitance changes because the finger acts as a conductor, so that the touch position can be detected. However, when the finger is in a non-conductive state (for example, the finger is dry, the stratum corneum is thick, or gloves are worn), the capacitance cannot be changed even if the finger touches the panel, resulting in touch failure.

[0003] Mutual capacitance touch panel can overcome the above-mentioned defects of self-capacitive touch panel. Mutual capacitance touch panel in the prior art usually includes two substrates arranged oppositely and spaced apart, a plurality of first electrodes and a plurality of second electrodes respectively arranged on the inner side of the two substrates, the plurality of first electrodes and the plurality of second electrodes are arranged crosswise in the vertical and horizontal directions, and the intersection area of ​​each first electrode and each second electrode constitutes a capacitor unit. When a finger presses a certain area of ​​the panel, the first electrode and the second electrode corresponding to the area are close to each other, thereby changing the capacitance value of the capacitor unit involved. Since the mutual capacitance touch panel is a touch panel that changes the capacitance value in response to the change in the distance between the electrodes caused by the pressing of the finger, even if the finger is in a non-conductor state, the touch operation of the finger on the panel is still effective.

[0004] However, the above mutual capacitive touch panel in the prior art still has the following defects:

[0005] 1. Based on the above, it can be known that the mutual capacitance touch panel changes the capacitance value based on the change in the distance between the electrodes. Obviously, configuring a sufficiently large initial distance between the two electrodes is conducive to obtaining a sufficiently large capacitance change range, thereby facilitating improving the touch detection accuracy of the electronic device. However, this is bound to lead to the undesirable result of an increase in the thickness of the panel surface.

[0006] 2. Although the touch pressure can be checked based on the change in capacitance value, so that the finger pressing force can be detected, and different touch purposes can be achieved by different pressing pressures, however, since the distance between the electrodes changes continuously and smoothly during the pressing process, the change in capacitance value is also continuous and smooth, making it difficult to define different touch purposes from the range of capacitance changes.

[0048] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0049] like Figure 1 As shown, the embodiment of the present invention discloses a touch panel 100, which is a core component of a touch display 500. The touch display 500 also includes a frame 400, a display panel 200 and a cover plate 300. The display panel 200 can be an LED panel, and the cover plate 300 can be a glass panel. The display panel 200, the touch panel 100 and the cover plate 300 are arranged in the frame 400 from the inside to the outside. When the touch panel 100 is pressed by the cover plate 300, the capacitance of the pressed area of ​​the touch panel 100 changes, thereby detecting the touch position. The present invention also discloses an all-in-one machine, which has a display with a touch panel 100 as a core component of the all-in-one machine.

[0050] like Figures 2 to 5As shown, the touch panel 100 includes: a first substrate 11, a second substrate 12, touch electrodes and a dielectric component 30; the first substrate 11 and the second substrate 12 are opposite to each other and are arranged at an interval, and the first substrate 11 is located on the outside of the second substrate 12, so that the pressure applied during touch acts on the first substrate 11; the touch electrodes include a plurality of first electrode strips 21 and a plurality of second electrode strips 22, the plurality of first electrode strips 21 are attached and fixed to the inner side surface of the first substrate 11 and are arranged longitudinally, and the plurality of second electrode strips 22 are attached and fixed to the inner side surface of the second substrate 12 and are arranged transversely, so that the first electrode strips 21 and the second electrode strips 22 are arranged crosswise vertically and horizontally, and the first electrode strips 21 and the second electrode strips 22 form capacitor units in each intersection area.

[0051] The dielectric component 30 is configured as a sheet structure, and the dielectric component 30 is between the planes defined by the plurality of first electrode strips 21 and the plurality of second electrode strips 22. The dielectric component 30 includes a supporting component 32 and a piezoresistance sheet 31; the supporting component 32 specifically includes a sheet body 321 and a hemispherical protrusion protruding from at least one surface of the sheet body 321, and the piezoresistance sheet 31 is overlapped with the sheet body 321, that is, the piezoresistance sheet 31 is overlapped with the sheet body 321 in the projection direction of the thickness. The sheet body 321 can be made of an etchable material; the piezoresistance sheet 31 is made of a material having a pressure-resistance effect, and the greater the pressure (compression force) on the piezoresistance sheet 31, the smaller its resistance.

[0052] The hemispherical convex body includes convex bodies of two sizes, namely, a first hemispherical convex body 3221 and a second hemispherical convex body 3222. The first hemispherical convex body 3221 and the second hemispherical convex body 3222 are arranged alternately, and the diameter of the first hemispherical convex body 3221 is larger than the diameter of the second hemispherical convex body 3222. Therefore, the first hemispherical convex body 3221 protrudes from the second hemispherical convex body 3222.

[0053] A plurality of dielectric holes 323 are provided on the support component 32, and the piezoresistive resistor 31 and the first electrode strip 21 and / or the second electrode strip 22 can have a plurality of exposure points through the dielectric holes 323. Since the dielectric constant of the capacitance value of the capacitor unit in the intersection area is determined by the dielectric component 30 in the intersection area, and the dielectric component 30 is composed of the support component 32 and the piezoresistive resistor 31, the influence of the support component 32 on the dielectric constant is significantly reduced by providing the dielectric holes 323, so that the dielectric constant is mainly determined by the piezoresistive resistor 31, specifically, by the resistance of the piezoresistive resistor 31. A more preferred arrangement position for the dielectric holes 323 is: the dielectric holes 323 are arranged at the position of the hemispherical convex body, so that the area where the resistance of the piezoresistive resistor 31 changes is used as an exposure point, because the sheet-like body 321 corresponding to the area has the most obvious influence (or interference) on the dielectric constant.

[0054] When the finger presses the first substrate 11, the pressed area produces a slight downward deformation and squeezes the supporting component 32, so that the hemispherical protrusion on the sheet component is squeezed due to contact with the first electrode strip 21, the second electrode strip 22 and / or the piezoresistive resistor 31, so that the hemispherical protrusion applies pressure to the piezoresistive resistor 31 opposite thereto, thereby changing the resistance of the piezoresistive resistor 31, thereby changing the dielectric constant of the corresponding capacitor unit, and then changing the capacitance value. The finger touch position can be detected based on the change in the capacitance value of the capacitor unit, and the magnitude of the finger pressing force can be detected based on the change in the capacitance value.

[0055] The touch panel 100 of the present invention is provided with a dielectric component 30 having a piezoresistive resistor 31 between two electrode strips, so that the capacitor unit in the pressurized area changes the capacitance value based on the change in the resistance of the piezoresistive resistor 31. Compared with changing the capacitance value based on the change in the distance between the electrodes, the distance between the electrodes can be set smaller, thereby meeting the thin and light design requirements of the touch panel 100.

[0056] Another key advantage of the present invention is that because the first hemispherical protrusion 3221 protrudes from the second hemispherical protrusion 3222, there are two situations based on different pressing forces: when the pressing force is small, only the first hemispherical protrusion 3221 squeezes the voltage-variable resistor 31 in its projection area; when the pressing force is large, the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 squeeze the voltage-variable resistor 31 in its projection area at the same time. It can be understood that the resistance change range of the voltage-variable resistor 31 caused by the simultaneous squeezing of the voltage-variable resistor 31 by the two hemispherical protrusions is significantly larger than the resistance change range of the voltage-variable resistor 31 caused by the squeezing of the voltage-variable resistor 31 by the first hemispherical protrusion 3221 alone. This is because the second hemispherical protrusion 3222 increases the pressure area of ​​the voltage-variable resistor 31 and the two hemispherical protrusions increase the degree of pressure on the voltage-variable resistor 31. More specifically, after the second hemispherical protrusion 3222 starts to participate in squeezing the voltage-variable resistor 31, the resistance of the voltage-variable resistor 31 suddenly decreases, resulting in a large span of the capacitance value of the capacitor unit before and after the squeezing of the second hemispherical protrusion 3222. Therefore, with the second hemispherical protrusion 3222 participating in changing the capacitance value as a dividing line, the electronic device (such as a touch-screen all-in-one machine) can distinguish two different strong and weak electrical signals, thereby defining a first touch purpose (corresponding to a low signal) and a second touch purpose (corresponding to a high signal). The first touch purpose is different from the second touch purpose. For example, the first touch purpose may be to request a certain application terminal to be opened, while the second touch purpose may be to request the application to be deleted.

[0057] The present invention provides several specific structures of the dielectric component 30 as follows.

[0058] The dielectric member 30 has a first specific structure.

[0059] like Figures 2 to 5 As shown, the piezoresistive resistor 31 is attached to the surface of the second strip electrode of the second substrate 12, and the hemispherical protrusions of the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 only protrude from the surface of the sheet body 321 of the supporting component 32 facing the second substrate 12, and the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 are integrally formed with the sheet body 321 and obtained by etching. The dielectric hole 323 is located at the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 and penetrates the supporting component 32, so that the piezoresistive resistor 31 forms an exposed point opposite to the first electrode strip 21 in the projection area of ​​the hemispherical protrusion.

[0060] When the first substrate 11 is under pressure, the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 successively apply pressure to the varistor 31 by directly contacting the varistor 31, thereby changing the resistance of the varistor 31, and then changing the capacitance value of the capacitor unit by changing the dielectric constant caused by the resistance change.

[0061] The second specific structure of the dielectric member 30 is shown.

[0062] like Figure 6 As shown, compared with the first specific structure, the second specific structure of the dielectric component 30 is characterized in that: the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 are formed on both surfaces of the sheet component, and the first electrode strip 21 of the first substrate 11 and the second electrode strip 22 of the second substrate 12 are attached to the varistor 31.

[0063] When the first substrate 11 is under pressure, the first hemispherical protrusions 3221 and the second hemispherical protrusions 3222 on both sides of the sheet body 321 successively apply pressure to the piezoresistive resistor sheets 31 on both sides by directly contacting the piezoresistive resistor sheets 31 on both sides. Compared with the first specific structure, after the second hemispherical protrusions 3222 participate in applying pressure to the piezoresistive resistor sheets 31, the dielectric constant of the capacitor unit changes to a greater extent.

[0064] The third specific structure of the dielectric member 30 is shown.

[0065] like Figure 7 As shown, a first hemispherical protrusion 3221 and a second hemispherical protrusion 3222 are formed on both surfaces of the sheet-like body 321. The difference from the first and second specific structures is that the varistor 31 is arranged in the sheet-like body 321 without being attached to the first electrode strip 21 and the second electrode strip 22, and the dielectric hole 323 passes through the top of the hemispherical protrusion to the varistor 31.

[0066] When the first substrate 11 is under pressure, the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 successively contact the first electrode strip 21 and the second electrode strip 22. The reaction force of the first electrode strip 21 and the second electrode strip 22 on the hemispherical protrusions causes the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 to apply pressure to the voltage-variable resistor 31 inside the sheet-like body 321, thereby changing the resistance of the voltage-variable resistor 31.

[0067] The significant advantage of the dielectric component 30 of the present structure is that the varistor 31 is in a non-electrically connected state with the first electrode strip 21 and the second electrode strip 22 due to the sheet-like body 321, so that the dielectric constant is only related to the resistance change of the varistor 31 itself and will not be affected by the contact state between the varistor 31 and the first electrode strip 21 or the second electrode strip 22. The dielectric constant of the dielectric component 30 of the first and second specific structures will also be affected by the contact state between the varistor and the electrode strips. For example, if the varistor 31 is partially separated from the electrode strips due to some reasons (for example, the varistor 31 is partially separated from the electrode strips due to bending or colloid aging), the dielectric constant will be affected.

[0068] A fourth specific structure of the dielectric member 30 is shown.

[0069] like Figure 8 and Fig. 9 As shown, the varistor 31 is attached to the first electrode strip 21 of the first substrate 11; the hemispherical protrusion protrudes from the surface of the sheet body 321 facing the second substrate 12; the first hemispherical protrusion 3221 of the hemispherical protrusion is formed on the surface of the sheet body 321 facing the second substrate 12; the second hemispherical protrusion 3222 of the hemispherical protrusion is electrically connected to the varistor 31, and the second hemispherical protrusion 3222 passes through the sheet body 321 and protrudes from the surface of the sheet body 321 facing the second substrate 12; the second hemispherical protrusion 3222 is a conductor; and the dielectric hole 323 passes through the sheet body 321 at the position of the first hemispherical protrusion 3221.

[0070] When the first substrate 11 is under pressure, the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 of the sheet-like body 321 contact the second electrode strip 22 successively toward the second substrate 12. The reaction force of the second electrode strip 22 on the hemispherical protrusion causes the first hemispherical protrusion 3221 and the second hemispherical protrusion 3222 to apply pressure to the voltage-variable resistor 31 on the first electrode strip 21, thereby changing the resistance of the voltage-variable resistor 31.

[0071] The advantages of the dielectric component 30 of this structure are:

[0072] Since the second hemispherical protrusion 3222 is a conductor and is electrically connected to the piezoresistive resistor 31, Fig. 9As shown, after the second hemispherical protrusion 3222 contacts the second electrode strip 22, the dielectric constant of the capacitor unit in the corresponding area of ​​the piezoresistive resistor 31 becomes very small due to the electrical connection between the second hemispherical protrusion 3222 and the second electrode strip 22. Therefore, before and after the second hemispherical protrusion 3222 contacts the second electrode strip 22, the capacitance value of the capacitor unit changes greatly, so that the electronic device (such as an all-in-one machine) obtains two electrical signals with significantly different intensities, thereby avoiding misjudgment of the touch purpose by the electronic device.
