Embodiment approach 1

[0053] figure 1 and figure 2 (a) represents the electronic device 100 (for example, a smartphone or a digital audio player) according to Embodiment 1 of the present invention. In electronic device 100 , a concave curved surface serving as operation surface 22A is formed on a predetermined surface area of ​​front panel 22 disposed on touch panel 12 . Hereinafter, a more specific configuration of the electronic device 100 will be described.

[0054] like figure 1 As shown, the electronic device 100 is configured so that the user can operate the front panel 22 while holding it with one hand (see figure 2 (a)) on the operation surface (touch surface) 22A. Since operation with one hand is assumed, the width W1 of the electronic device 100 is typically set to be 40 mm or more and 70 mm or less.

[0055] figure 2 (a) shows the cross-sectional structure of the electronic device 100 . The electronic device 100 has a display device 10 and a touch panel 12 provided as a laminat...

Embodiment approach 2

[0101] Figure 7 A cross section of electronic device 102 according to Embodiment 2 is shown. The structure of the electronic device 102 is substantially the same as that of the electronic device 100 according to Embodiment 1, except that the touch panel 32 and the display device 30 are bent plate shapes. In addition, the front panel 42 and the housing 40 have shapes capable of properly holding the touch panel 32 and the display device 30 .

[0102] In the electronic device 102 of this embodiment, since the touch panel 32 and the display device 30 are in the shape of a curved plate, they are preferably formed using a flexible base material such as resin. For example, the electronic device 102 can be manufactured by forming the touch panel 32 and the display device 30 using a PET film with a thickness of 0.2 mm or the like as a base material, and bonding them to the curved plate-shaped front panel 42 .

[0103] Also in this embodiment, the operation surface 32A of the touch p...

Embodiment approach 3

[0105] Figure 8 (a) and (b) show the cross section of the electronic device 103 of Embodiment 3, and (b) shows enlarged the part surrounded by the dotted line in (a).

[0106] The electronic device 103 of the present embodiment differs from the electronic device 100 of the first embodiment in that the end portion 52B of the front panel 52 has a convex curved surface 22B having a curvature intentionally set, and the front panel 52 has The end portion 52B is arranged to overlap both the display region 10A and the frame region 10F of the display device 10 .

[0107]In such a configuration, the front panel 52 has, on its surface, an operation surface 22A formed of a concave curved surface, and a convex curved surface 22B arranged outside the operation surface 22A. The end portion 52B of the front panel 52 can refract light emitted from the peripheral portion of the display area 10A of the display device 10 (may be referred to as a peripheral display area).

[0108] Thus, in the...

Abstract

An electronic device (100) has a touch panel (12) and a display (10) as a deposited layered structure. An operating surface (22A) for receiving input from the user is provided on the surface of the touch panel. The center part of the operating surface (22A) is a curved surface that is depressed compared to the end of the operating surface (22A). The most concave part of the operating surface (22A) is depressed by only the distance of at least 0.2 mm to no more than 3.0 mm in the direction perpendicular to the panel surface with respect to the end of the operating surface (22A).

Description

technical field [0001] The present invention relates to electronic equipment, and particularly to electronic equipment provided with a touch panel display device. Background technique [0002] In recent years, smart phones, digital audio players, portable game machines, tablet terminals, etc. equipped with touch panel display devices have been widely used. By using the touch panel, more intuitive input can be performed on the screen. In addition, when a touch panel is used, it is also possible to obtain an advantage that the number of physical buttons provided in the electronic device can be reduced. Therefore, it can be considered that the touch panel will be very promising in the future, especially as an input device for various small electronic devices having portability. [0003] The number of users of smartphones equipped with touch panels is increasing year by year. Under such circumstances, there are many opportunities to operate the touch panel while holding the s...
