More specifically, the antenna 120 installed in the cellular phone body 100 serves to receive high frequency reception data received from the outside and to transmit high frequency transmission data to the outside.

Specifically, the signal processing device 300 installed in the mobile phone body 100, when the received signal is input from the outside, processes the received signal to generate an analog signal that can be output from the speaker so that the voice is output from the speaker.

In addition, the signal processing device 300 installed in the mobile phone body 100 generates a signal for the display device so that the corresponding data is displayed on the display device 170 which will be described later in detail.

On the other hand, the signal processing device 300 installed in the mobile phone body 100 is a predetermined signal after the voice signal is input to the microphone 113 by the user, converts the voice signal into a digital signal to the outside through the antenna 120 Send.

In addition, the signal processing device 300 installed in the mobile phone body 100 generates a signal for the display device so that the corresponding data is displayed on the display device 170.

On the other hand, the mobile phone body 100 is formed with a keypad 110 consisting of a number pad for the user dialing for a phone call and a function key for performing various functions.

At this time, the keypad 110 is further provided with a lamp on / off key (115) for turning off the lamp of the display device 170 to be described later in detail.

The lamp on / off key 115 of the keypad 110 serves to supply or cut power to the lamp from an inverter module (not shown) that supplies power to the lamp.

Meanwhile, in one embodiment, the display body 150 is provided with a display device 170 and a speaker 160 which serve to display various data to be displayed on the mobile phone 1 as an image.

In this case, various types of display devices 170 installed on the display body 150 may be installed.

For example, the display device 170 may be a liquid crystal display device in which a display is performed by a backlight assembly or a self-luminous display device in which a display is performed by emitting light by itself.

In this case, a plasma display panel (PDP), an organic electroluminescent device, or the like may be used as the self-emission display device.

Although all of them may be used in the present invention, a liquid crystal display using liquid crystal will be described as a preferred embodiment.

3 illustrates a liquid crystal display device 170.

The liquid crystal display 170 is generally composed of a liquid crystal display panel assembly 172 and a backlight assembly.

The liquid crystal display panel assembly 172 performs a function of precisely controlling the arrangement angle of the liquid crystal injected between the two electrodes to change the light transmittance that can pass through the liquid crystal in units of minute areas.

In order to realize this, the liquid crystal display panel assembly 172 is a liquid crystal composed of a TFT substrate (172a), a color filter substrate (172b), and liquid crystal injected therebetween serving as two opposite electrodes. A liquid crystal display panel 172c and a control module (not shown) for controlling the liquid crystal injected into the liquid crystal display panel 172c.

In detail, the TFT substrate 172a may generate a voltage change in a very small area unit in response to an image signal applied from the outside, and the color filter substrate 172b serves as an electrode and at the same time, white light serves as the three primary colors of light. It plays a role of filtering by any one of them.

Specifically, the control module determines the timing of operating the thin film transistors and the strength of the power to be supplied to each thin film transistor. The control module includes a gate printed circuit board, a source printed circuit board, and a flexible printed circuit.

On the other hand, even when the control module precisely controls the liquid crystal display panel described above, no light is generated in the liquid crystal display panel assembly 172.

This is because the liquid crystal, which is a component of the liquid crystal display panel assembly 172, does not generate light by itself but precisely controls the amount of light transmitted.

That is, display can never be performed without light passing through the TFT substrate 172a, the liquid crystal, and the color filter substrate 172b.

In order to overcome this problem, the backlight assembly 175 is used in the present invention.

The backlight assembly 175 again includes a light guide plate 177, an optical sheet 174, a reflector 179, a lamp assembly 176, and an inverter module.

The lamp assembly 176 again includes a cold cathode ray tube lamp 176a and a lamp cover (not shown), and the lamp assembly 176 is turned on / off by applying power applied from the inverter module.

In this case, the inverter module supplies / blocks power to the lamp 176a by the lamp on / off key 115 of the keypad 110 as described above.

The light guide plate 177 is again coupled to the lamp assembly 176.

The light guide plate 177 not only causes the light generated from the lamp 176a of the lamp assembly 176 to have a surface light source distribution, but also directs the light toward the liquid crystal display panel assembly 172 described above.

In this case, in order to reproduce the light leaked from the light guide plate 177, a reflecting plate 179 is formed on the bottom surface of the light guide plate 177, and a plurality of optical sheets 174 are installed on the top surface of the light guide plate 177.

Meanwhile, the reflecting plate 179, the light guide plate 177, the lamp assembly 176, and the optical sheets 174 are all stored in the storage container 178 in order, and the lamp assembly (finally, the upper portion of the storage container 178). 172 is fixed.

The liquid crystal display device 170 as described above is embedded in the mobile phone body 100 of the mobile phone 1 or inside the display body 150 hingedly coupled with the mobile phone body 100 as shown in FIG. 1, In order to protect the liquid crystal display device 170, a protective panel 185 is installed in the display body 150 where the liquid crystal display device 170 is opened to be embedded.

On the other hand, the display body 150 corresponding to the protection panel 185 and the liquid crystal display device 170 is provided with a reflection / transmission glass 180.

The reflective / transmissive glass 180 is thinly coated on a transparent glass substrate with a predetermined metal having a high reflectance to a thickness of several tens to thousands of microseconds to form a metal thin film 182.

As described above, the reflective / transmissive glass 180 on which the metal thin film 182 is formed is turned on by the user on the lamp on / off key 115 of the keypad 110 or at the same time the transmission data is input from the outside. When turned on, the light transmitted from the liquid crystal display device 170 may be transmitted so that a user may read the information displayed on the liquid crystal display panel assembly 172.

Meanwhile, the reflective / transmissive glass 180 on which the metal thin film 182 is formed may be turned off by the user to turn off the lamp on / off key 115 of the keypad 110 or the cellular phone 1 may be in a standby state. When the lamp 176a of the liquid crystal display 170 is turned off for various reasons, the external light reflects external light to have a mirror function.

Alternatively, when the user does not operate the lamp on / off key 115 to turn off the lamp 176a, the mobile phone 1 may display various information such as time, reception, date, and the like. While displaying data, when the user operates the lamp on / off key 115 and the lamp 176a is turned off, when the lamp 176a of the liquid crystal display 170 is turned off, external light is reflected to have a mirror function. can do.

When the organic electroluminescent device or the plasma display panel (PDP) is installed on the back of the reflective / transparent glass 180 to perform the above function, the power of the organic electroluminescent device and the plasma display panel is turned off. By turning off, the reflection / transmission glass 180 can be used as a mirror, and can be used as a display device when performing display from an organic electroluminescent device and a plasma display panel.

Referring to the operation of the mobile phone which is one of the portable information processing apparatus of the present invention configured as described above is as follows.

When the mobile phone 1 is not used, for example, when there is a call waiting or when no signal is input from the outside, or when the user presses the lamp on / off key 115 and the lamp 176a is turned off, No information is displayed by the liquid crystal display panel assembly 172.

Then, the inner side of the reflection / transmission glass 180 installed in front of the liquid crystal display panel assembly 172 is in a dark room state, and the metal thin film 182 coated on the reflection / transmission glass 180 reflects light introduced from the outside. Therefore, the portion of the mobile phone 1 in which the liquid crystal display device 170 is installed serves as a mirror.

On the other hand, in order to view the date or time displayed on the liquid crystal display panel assembly 172, by pressing the designated lamp on / off key 115 to forcibly turn on the lamp 176a, press any key button, or make a telephone call. When the key button 110 is pressed to make a call or input information to the mobile phone 1, a lamp is turned on when a call is made.

In this case, since the illuminance of the light passing through the liquid crystal display panel assembly 172 is higher than the external illuminance, the reflection / transmission glass 180 is converted into a transparent state that transmits light.

Therefore, as shown in FIG. 3, the user can easily read the contents of the information displayed on the liquid crystal display panel assembly 172 through the protection panel 185.

On the other hand, when the mobile phone 1 is used differently, for example, when a received data is being input during a call or externally, or when the user presses the lamp on / off key 115 and the lamp 176a is turned on, the liquid crystal The display panel assembly 172 always displays predetermined information.

Thereafter, when the user presses the lamp on / off key 115 to turn off the lamp 176a, the lamp 176a is turned off and no information is displayed on the liquid crystal display 170.

In this case, the inner side of the reflective / transparent glass 180 installed in front of the liquid crystal display panel assembly 172 is in a dark room, and the metal thin film 182 coated on the reflective / transparent glass 180 is introduced into the light. Since the light is reflected, the portion of the mobile phone 1 in which the liquid crystal display device 170 is installed serves as a mirror.

As described above, the present invention provides a portable display device by providing a reflection / transmission glass having a mirror function in front of the liquid crystal panel by transmitting light when the liquid crystal panel is emitted by lighting the lamp and reflecting light when the lamp is turned off. Product value of the can be increased, there is an advantage that does not need to carry a mirror separately.

In the present invention, a separate reflective / transparent glass is provided in the protective panel and the liquid crystal display as a preferred embodiment. Alternatively, even when the protective panel uses the reflective / transmissive glass, the operation and effect are the same as those in the exemplary embodiment of the present invention. You will be able to get
