Problems solved by technology

[0008] However, when the input contact object in contact with the touch panel is reduced, the change in electrostatic capacitance becomes smaller, the input signal to the touch panel becomes smaller, and there is a problem that the sensitivity of the touch panel due to the user's input action deteriorates.

no. 1 approach

[0035] figure 1 It is a schematic cross-sectional view of the touch panel 1 with a display device. Such as figure 1 As shown, the touch panel 10 according to the first embodiment of the present invention has a sensing pattern 13 formed between a glass substrate 11 mounted on a display device 20 and a cover glass 12 contacted by a contact object 30. The sensing pattern 13 is used to sense whether the contact object 30 is in contact with the cover glass 12. By mounting the display device 20 on the glass substrate 11 side of the touch panel 10, the touch panel 1 with a display device is obtained.

[0036] Since the glass substrate 11 requires a predetermined strength, physically strengthened glass, chemically strengthened glass, etc. are used, and chemically strengthened glass is preferably used. The chemically strengthened glass used in the present invention is preferably used as a glass composition containing 50 to 80% of SiO by mass 2 , 5~25% Al 2 O 3 , 0~15% of B 2 O 3 , 1~20% ...

[0058] image 3 It is a diagram of the touch panel with a display device 1 equipped with the touch panel 10 according to the second embodiment of the present invention. In the touch panel 10 according to the second embodiment of the present invention, the sensing pattern 13 is formed on the cover glass 12, and then the adhesive layer 14 is laminated to bond the glass substrate 11. The specific structures of the glass substrate 11, the cover glass 12, the sensing pattern 13, and the adhesive layer 14 are the same as those of the above-mentioned first embodiment. According to this embodiment, unlike the first embodiment, by using a glass roll as the cover glass 12, the sensing pattern 13 can be formed in a roll-to-roll manner, and the manufacturing efficiency of the touch panel 10 is improved. Furthermore, by forming the sensing pattern 13 on the cover glass 12 side, the distance from the contact object 30 to the sensing pattern 13 can be shortened, and the sensitivity of the tou...

no. 3 approach

[0060] Figure 4 It is a diagram of the touch panel 1 with a display device equipped with the touch panel 10 according to the third embodiment of the present invention. In the touch panel 10 according to the third embodiment of the present invention, the first electrode 13b is formed on the glass substrate 11, the second electrode is formed on the cover glass 12, and the glass substrate 11 and the cover glass 12 are connected via the adhesive layer 14. By bonding, the touch panel 10 is produced. In this embodiment, the adhesive layer 14 also functions as the insulating layer 13a. Thereby, the cost and time for forming the insulating layer 13a can be reduced. The specific structures of the glass substrate 11, the cover glass 12, the first electrode 13b, the second electrode 13c, and the adhesive layer 14 are the same as those of the first embodiment described above.

Abstract

A touch panel (10) for sensing a contact object (30), the touch panel being characterized in having: a glass substrate (11); a cover glass (12) which comes in contact with the contact object (30); and a sensing pattern (13) disposed between the glass substrate (11) and the cover glass (12), the sensing pattern (13) sensing that the contact object (30) has touched the cover glass (12), the glass substrate (11) being configured from tempered glass, and the cover glass (12) being configured from a glass film. A display-device-fitted touch panel (1) is realized by attaching a display device (20) to the glass substrate (11) side of the touch panel (10).

Description

Technical field [0001] The present invention relates to touch panels used in mobile phones, smart phones, tablet PCs, notebook PCs, bank ATMs, ticket vending machines, and the like. Background technique [0002] Traditionally, touch panels have been used in ticket vending machines such as bank ATMs, gaming machines, railways and buses. By mounting the touch panel in the display device, the device can be operated visually and intuitively based on the information displayed on the display device. Therefore, the device equipped with the touch panel has the advantage of easy operation. [0003] In addition, the touch panel can be equipped with an input device in the display device. Therefore, there is no need to separately provide an input device, and the overall size of the device can be reduced. Therefore, in recent years, touch panels have been appropriately used in mobile phones, smart phones, portable game devices, tablet PCs, and notebook PCs that require miniaturization. [0004]...
