- an optimum method is selected according to the application and environment.
- use of touch sensors that enable complex input operations using a multipoint detection function that detects the positions of a plurality of locations touched simultaneously has been advanced.
- a detection method of the touch sensor capable of multipoint detection there is a projection capacitive method.
- Patent Document 1 As a projected capacitive touch sensor, for example, there is an apparatus described in Patent Document 1.
- a plurality of electrodes (first electrode group) are formed on one surface of a sheet having a predetermined dielectric constant so as to run parallel to each other, and the first surface is formed on the other surface of the sheet.

In either case, the strength is improved by forming a compressive stress layer on the surface of the glass.

- a surface glass for a capacitive touch sensor that has a high strength and a low dielectric constant, and can be suitably used particularly for a projection capacitive touch sensor.
- FIG. 1 is a schematic cross-sectional view showing a configuration of a projected capacitive touch sensor 1 including a surface glass 2 for a capacitive touch sensor (hereinafter sometimes referred to as surface glass) according to an embodiment of the present invention.
- the capacitive touch sensor 1 shown in FIG. 1 has a surface glass 2, a substrate 3, an X-direction electrode 4 and a Y-direction electrode 5 formed between the surface glass 2 and the substrate 3, and these electrodes are separated from each other. And an insulating layer 6 for this purpose.
- one of the X direction electrode 4 and the Y direction electrode 5 is configured as a reception electrode, and the other is configured as a transmission electrode.
- the receiving electrode side is grounded to GND and a pulse is input from the transmitting electrode side, an electric field (Field coupling) is generated between the electrodes (when not touched).
- a position indicating member such as a finger or a stylus approaches the surface of the surface glass 2
- a part of the electric field is generated between the transmission electrode and the human body
- the electric field between the reception electrode and the transmission electrode decreases. Yes (when touched).
- the contact of the position indicating member is detected and the contact position is specified by measuring the decrease in the electrostatic capacity accompanying the decrease in the electric field between the non-touch and the touch.
- the capacitance at the time of non-touch includes capacitance between adjacent electrodes (interline capacitance) of each detection electrode, capacitance due to the intersection of the X direction electrode and the Y direction electrode, and stray capacitance.
- the distance between the adjacent electrodes is reduced. Thereby, a high-resolution touch sensor can be obtained.
- the relative permittivity at a frequency of 1 MHz is 4.5 to 6.9 for the surface glass 2 that is one of the coupling paths between the adjacent electrodes. Glass is used.
- the capacitance between adjacent electrodes and even if the distance between adjacent electrodes is narrowed, position detection with high accuracy is possible, and there is no possibility of increasing the manufacturing cost.
- the glass having the above-described relative dielectric constant is used for the surface glass 2, the amount of decrease in the electrostatic capacity due to the decrease in the electric field between non-touch and touch is reduced.
- the relative dielectric constant of the surface glass 2 is less than 4.5, it is difficult to obtain a glass having high strength by chemical strengthening treatment for the reason described later. On the other hand, if it exceeds 6.9, the capacitance at the time of non-touch increases, and it becomes difficult to detect the position with high accuracy.
- the relative dielectric constant of the surface glass 2 is preferably 4.8 to 6.8, and more preferably 5 to 6.5.
- the amount of alkali metal components (Na, K, Li) present in the glass greatly affects the formation of a compressive stress layer on the glass surface due to the dielectric constant and chemical strengthening.
- the relative permittivity tends to decrease as the alkali metal component decreases.
- the compressive stress layer formed on the glass surface by the chemical strengthening treatment tends to increase as the amount of the alkali metal component increases. Therefore, in glass, reducing the relative dielectric constant and increasing the compressive stress layer formed on the glass surface by chemical strengthening treatment conflicts with the content of the alkali metal component in the glass.
- the surface glass 2 of the present invention can achieve both a low relative dielectric constant and a high strength by chemical strengthening by setting the relative dielectric constant to 4.5 or more.
- the surface glass 2 is a glass having high strength by providing a compressive stress layer on the surface by chemical strengthening treatment.
- the method of chemical strengthening treatment is not particularly limited as long as, for example, Na ions on the surface of the glass and K ions in the molten salt can be ion-exchanged.
- the glass is immersed in a heated potassium nitrate (KNO 3 ) molten salt.
- the chemical strengthening treatment conditions for providing a compressive stress layer on the surface of the glass vary depending on the thickness of the glass, but it is typical to immerse the glass in KNO 3 molten salt at 400 to 550 ° C. for 2 to 20 hours. .
- the chemical strengthening treatment of the surface glass 2 is performed by the immersion method as described above, it is possible to form a compressive stress layer on both surfaces of the surface glass 2 and to obtain a surface glass with higher strength, which is preferable.
- the surface glass 2 has a compressive stress layer depth of 5 to 50 ⁇ m by chemical strengthening treatment. The reason is as follows.
- a polishing step may be performed.
- the grain size of polishing abrasive grains used for the final stage polishing is typically 2 to 6 ⁇ m, and such abrasive grains ultimately cause the glass surface to have a maximum of 5 ⁇ m micron. It is thought that a crack is formed.
- the chemical strengthening treatment it is necessary to have a compressive stress layer deeper than the microcracks formed on the glass surface, so the depth of the compressive stress layer generated by the chemical strengthening treatment Is 5 ⁇ m or more.

他方、位置指示部材の接触位置を高い精度で検出するため、それぞれの隣接電極間の距離を狭くすることが行われる。これにより解像度の高いタッチセンサが得られる。しかしながら、隣接電極間の距離を狭くすると、同一のタッチセンサ面積における電極長さが長大となること、および隣接電極間の距離が小さくなること、の両者によって隣接電極間容量が非常に大きくなる。これにより、非タッチ時の静電容量が大きくなり、非タッチ時の静電容量とタッチ時の静電容量変化との比率が小さくなることで検出精度が低下するおそれがある。また、非タッチ時の静電容量が大きくなると、静電容量を検出するセンサーICの検出範囲の上限が大きいものを用いる必要があり、タッチセンサの製造コストが高くなったり、消費電力が大きくなるという不具合がある。
表面ガラス2の比誘電率が4.5未満であると、後述する理由で化学強化処理により強度の高いをガラスを得ることが困難となる。また、6.9を超えると、非タッチ時の静電容量が大きくなり、高い精度の位置検出が難しくなる。表面ガラス2の比誘電率は、好ましくは4.8~6.8であり、より好ましくは5~6.5である。
