Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mobile phone equipped with a backlight type liquid crystal display unit, and more particularly to a mobile phone capable of displaying a character image on the liquid crystal display unit and improving accessories.

[0002]

[Prior art]

 In recent years, the spread of mobile phones has been remarkable, and the service area has been expanded from almost the entire urban area to the surrounding areas, and many young people, not just adults, use mobile phones.

[0003]

[Problems to be solved by the invention]

 When many young people and young people use mobile phones, mobile phones are being carried as one of the accessories, but mobile phones are inherently wireless communication devices. In addition, there is a demand for a mobile phone with low accessibility and accessibility that suits the preferences of young people.

Therefore, a fancy character seal has been applied to the surface of a mobile phone to improve accessibility. However, it is easy to remove the character seal simply by attaching the character seal to the outer surface of the case. Was not so high.

[0005] The present invention has been made to solve the above-described problems, and has as its object to provide a mobile phone capable of improving accessories and fashionability.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a mobile phone according to the present invention is a mobile phone having a backlight type liquid crystal display unit, wherein the liquid crystal display unit includes a liquid crystal panel and a backlight panel located on the back side thereof. A character sticker on which a character image is printed is provided between the liquid crystal panel and the backlight panel.

Here, the backlight panel can be configured to guide light from the light emitting diode through the edge, and diffuse and emit the light from the surface.

[0008]

[Effects and effects of the invention]

 In such a mobile phone, when the backlight is turned on in response to a switch operation, light from the backlight panel passes through the liquid crystal panel and is emitted to the front, so that the characters of the light-shielding portion displayed in the liquid crystal panel are displayed. And symbols are displayed in the background of the backlight, and the character image of the character seal disposed between the liquid crystal panel and the backlight panel is displayed slightly thinner on the liquid crystal panel.

At this time, since the character seal is located on the back side of the liquid crystal panel, the display of the liquid crystal panel is not difficult to see due to the image of the character, and a fancy character image is displayed. Fashion and accessories can be enhanced. Also, since the character sticker is attached to the inside of the liquid crystal display, it does not peel off as when it is attached to the outer surface, and the character image can be projected well with a simple structure.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view of a mobile phone, and FIG. 2 is a cross-sectional view of a display unit thereof. Reference numeral 1 denotes a telephone case. A liquid crystal display unit 2 and a switch operation unit 3 are provided on an upper surface of the case 1, a microphone unit 4 is provided on a lower part of the upper surface of the case 1, and a speaker unit 5 is provided on an upper part. Can be

Although a detailed description of the electronic circuit in Case 1 is omitted, a receiving unit that receives a telephone transmission signal transmitted from the transmission facility, demodulates the received signal, and outputs the demodulated signal as a voice signal. An audio signal circuit, a transmission audio circuit that modulates the transmission audio signal obtained from the microphone unit 4 and sends it to the transmission unit, a transmission unit that transmits the signal on a carrier wave of a predetermined frequency, and a telephone unit A telephone circuit and the like including an incoming call detection circuit and the like are provided on the lower surface of the print board.

A switch unit including a numeric key switch and other function switches is provided on a printed circuit board in the case 1, and performs a switching operation in accordance with an operation of the switch operation unit 3 located thereon. .

On the other hand, a transparent cover 6 is provided on the liquid crystal display section 2 formed on the upper part of the upper surface of the case, and a liquid crystal panel 7 is provided on a printed circuit board 8 inside the transparent cover 6 as shown in FIG. It is arranged through a section.

The liquid crystal panel 7 is formed by laminating a polarizing plate and a liquid crystal cell, and the liquid crystal cell is formed by filling a liquid crystal layer between transparent electrode substrates. That is, a transparent electrode and an alignment layer are stacked on a pair of glass substrates, and a liquid crystal material is filled between the glass substrates to form a liquid crystal cell.

The liquid crystal display unit 2 is of a backlight type, and an edge type backlight panel 10 is disposed on the back of the liquid crystal panel 7. The backlight panel 10 disposed in the backlight case 9 is formed of a light-diffusing diffusion plate, and the diffusion plate is provided with an incident portion at an edge of a synthetic resin plate having a light-guiding property, and has a front surface (front surface). The surface is formed with fine irregularities so that light is diffused and emitted uniformly from the surface. At the edge of the backlight panel 10 made of a diffusion plate, a reflection plate 12 is provided so as to be inclined at an angle of 45 °, and a light emitting diode 11 is provided on a printed circuit board 8 therebelow.

Furthermore, a character seal 13 is disposed on the backlight panel 10, that is, between the backlight panel 10 and the liquid crystal panel 7. The character seal 13 is, for example, a character such as an animation or a cartoon printed on a transparent base film. The character seal 13 is adhered to the backlight panel 10 with an adhesive applied to the back surface by peeling off the release paper on the back surface. The character seal 13 is printed on a transparent film using color ink, but has a light-transmitting property because the printing layer is thin.

In the mobile phone configured as described above, when a power switch or the like of the switch operation unit 3 is turned on and a numeric keypad or the like is operated, a number or code is displayed on the liquid crystal display unit 2 in accordance with the switch operation. The display of the liquid crystal display unit 2 is performed by selectively applying an electric field to the liquid crystal cell of the liquid crystal panel 7 so as to control the light transmitting and light shielding properties of the liquid crystal layer. At this time, in the backlight of the liquid crystal display unit 2, the light emitting diode 11 is turned on, and the light of the light emitting diode 11 enters the backlight panel 10 from the edge via the reflector 12.

The light incident on the backlight panel 10 from the edge is diffused by the action of the diffusion plate and is radiated upward as planar light from the front surface. The planar light is transmitted through the character seal 13 and the liquid crystal. The light is radiated upward from the liquid crystal display unit 2 through the panel 7. For this reason, the characters and codes displayed on the liquid crystal panel 7 are displayed on the liquid crystal display unit 2 in the backlight, and the image of the character seal 13 is also displayed.

The liquid crystal panel 7 displays characters and codes by selectively transmitting light in other portions without transmitting light only in places where characters and codes are displayed. The image of the character seal 13 arranged between the liquid crystal panel 10 and the liquid crystal panel 7 is displayed through the liquid crystal panel 7.

The image of the character seal 13 is displayed to be slightly thinner than the display image of the liquid crystal panel 7 and does not disturb the display of the liquid crystal panel 7, but the character image is raised in the backlight. Will be displayed.

Accordingly, when a mobile phone is used, a cute or adorable character image is displayed on the liquid crystal display unit 2, so that the accessory and fashion of the phone can be improved.
