Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone and a PHS
The present invention relates to a liquid crystal touch panel used for an electronic device using the liquid crystal touch panel, such as a liquid crystal touch panel.

[0002]

2. Description of the Related Art Conventionally, as this kind of electronic equipment, there is an electronic equipment in which a liquid crystal touch panel is provided on an upper surface of an equipment body or the like.

The conventional liquid crystal touch panel has a two-layer structure in which a touch panel b is provided on the upper surface of a film liquid crystal a on which an information input section for inputting information such as a telephone number is displayed as shown in FIGS. When inputting information such as a telephone number, when the information input unit c displayed on the film liquid crystal a is pressed with a finger or the like from above the touch panel b, a contact (not shown) provided on the touch panel b is turned on, It is configured to allow you to enter information such as phone numbers,
As a liquid crystal touch panel having such a configuration, for example, a liquid crystal touch panel described in Japanese Patent Application Laid-Open No. 8-234162 is known.

[0004]

However, in the above-mentioned conventional liquid crystal touch panel, since there is no clicking feeling when the touch panel b is pressed, the pressing feeling cannot be obtained. There was a difficulty in the operability, such as the need to check with eyes.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and provides a liquid crystal touch panel capable of providing a click feeling when a touch panel is pressed, thereby improving operability and improving telephone operability. The purpose of this is to ensure that the information can be input.

[0006]

According to the present invention, in order to achieve the above object, a finger or the like presses the information input unit under a film liquid crystal on which an information input unit for inputting information such as a telephone number is displayed. A flam that provides a click feeling is provided, and a sensation of "pressing a button" is obtained by the click feeling, so that operability is improved and information can be input without fail.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the first aspect of the present invention, there is provided a film liquid crystal on which an information input portion for inputting information such as a telephone number is displayed, and a back surface with respect to a display surface of the film liquid crystal. Is provided with a flam formed of an elastic body and provided with a protruding portion located at the information input portion displayed on the film liquid crystal.

With the above arrangement, when the information input section is pressed with a finger or the like to input information, the protruding portion of the flam buckles and a click feeling is obtained, so that the user has a feeling of "pressing a button". And the operability is improved.

According to a second aspect of the present invention, there is provided a touch panel having a contact point for each information input section of the flam with respect to the display surface of the film liquid crystal.

With the above arrangement, when the information input section of the film liquid crystal is pressed with a finger or the like from the touch panel, the contacts in the touch panel are turned on, and information can be input.

According to a third aspect of the present invention, there is provided a printed circuit board having a flam formed of a conductor and having a conductive pattern for each information input section, and the flam being provided on an upper surface of the printed circuit board. Thus, a touch panel is formed.

With the above structure, when the information input portion of the film liquid crystal is pressed with a finger or the like, the protrusion of the flam buckles and a click feeling is obtained, and at the same time, the flam conducts the contact pattern of the printed circuit board. You will be able to input.

An embodiment of the present invention will be described below with reference to FIGS.
This will be described in detail with reference to the drawings shown in FIG.

FIG. 1 is an exploded perspective view of the liquid crystal touch panel, and FIG. 2 is a sectional view of the assembled state.

In these figures, reference numeral 1 denotes a liquid crystal touch panel main body, which is composed of a film liquid crystal 2, a touch panel 3 superposed on the display surface thereof, and a printed board 4 provided on a portion of the display surface of the film liquid crystal 2 on the back side. A flam 5 for obtaining a click feeling during operation is interposed between the film liquid crystal 2 and the printed circuit board 4.

The film liquid crystal 2 has an information input section 2a for inputting information such as a telephone number on a film of an appropriate size.
The touch panel 3 overlapped on the display surface of the film liquid crystal 2 is formed of a transparent material so that the information input section 2a displayed on the film liquid crystal 2 can be seen from above the touch panel 3. The information input unit 2a displayed on the film liquid crystal 2 is provided with a contact (not shown) therein. When the information input unit 2a is pressed with a finger or the like via the touch panel 3, these contacts in the touch panel 3 are provided. Are configured to be conducted.

As shown in FIG. 2, the flam 5 interposed between the printed circuit board 4 and the film liquid crystal 2 has a hollow hemispherical protruding portion 5a protruding for each information input portion 2a of the film liquid crystal 2. The entire structure is integrally formed of a soft synthetic resin or the like, and the bottom surface is adhered to the upper surface of the printed circuit board 4 by an adhesive means 6 such as an adhesive tape.

Next, the operation of the liquid crystal touch panel constructed as described above will be described. The liquid crystal touch panel is used mainly for portable electronic devices such as mobile phones and PHSs. In order to input the information of the
Is pressed by a finger or the like, a buckling occurs on the protruding portion 5a of the flam 5 interposed between the film liquid crystal 2 and the printed circuit board 4 to generate a click feeling.

As a result, the user can feel that "the button has been pressed", so that the user does not need to confirm it visually every time the information is input, and the projecting portion 5 of the flam 5 can be used.
Since the contact point in the touch panel 3 is made conductive by the reaction force when a buckles, information can be input reliably.

In the above embodiment, the protrusions 5a of the flam 5 are made the same size. However, the size and interval of the protrusions 5a are changed according to the size of the information input portion 3a displayed on the film liquid crystal 3. Of course, it is good.

In the above embodiment, the film liquid crystal 2
The touch panel 3 is provided on the display surface of
The touch panel 3 on the film liquid crystal 2 may be eliminated by forming the touch panel 3 on the film liquid crystal 2 by forming a contact pattern on the printed board 4 by forming a contact pattern on the printed circuit board 4.

[0022]

As described in detail above, according to the present invention, a flam having a projecting portion for each information input portion is provided on a portion of the film liquid crystal on which the information input portion is displayed on the back surface with respect to the display surface. Therefore, when the information input unit displayed on the film liquid crystal is pressed with a finger or the like, the protruding portion of the flam buckles, and a click feeling can be obtained.

With this, the user "pressed the button".
This eliminates the need for a visual check every time information is input, greatly improving operability, and the contact point of the touch panel is turned on by the reaction force when the protrusion buckles. Therefore, information can be input reliably.
