Abstract

PROBLEM TO BE SOLVED: To eliminate the problem when a mirror is provided at the rear surface of a mobile radio equipment, of the mirror being damaged easily and restrictions being added to the design process. SOLUTION: A liquid crystal mirror 5 is bonded to the surface of a terminal liquid crystal display 4 of the display 3 of the mobile radio equipment and this mirror 5 is protected with a protection cover 6. When a power switch of the terminal is set to 'on', a voltage is applied to a transparent electrode layer of the liquid crystal mirror 5, the liquid crystal mirror 5 change to the transparent condition. Therefore, it is possible to observe the display of the terminal liquid crystal display 4. When the power switch of the terminal is set to 'off', the voltage having been applied to the transparent electrode layer of the liquid crystal mirror 5 is cut off, and the liquid crystal mirror 5 changes to the mirror condition. Therefore, this display 3 may be used as a mirror.

However, the conventional portable telephone has a very small telephone body,
In addition, many cases have a case design with many curved surfaces in consideration of ease of holding. Therefore, there is a problem that the area of the mirror attached to the telephone is small, and the usability is poor. In addition, when a mirror is stuck, there has been a problem that the mirror is easily peeled. Furthermore, if the telephones are stored in a handbag or the like together with other portable items, there is a problem that the telephones come into contact with each other in the handbag and the mirror surface is damaged. Also,
For example, if this phone is placed on a desk with the back of the mirror facing down with the operation surface facing up, and this phone is shifted on the desk, the mirror surface and the desk will rub and the mirror surface will be scratched The problem of sticking occurs. On the other hand, a cover for protecting the mirror surface may be provided in some cases, but this protective cover has a problem that the telephone is bulky and inconvenient. In addition, because it requires a certain flat part to fit and paste the mirror,
There is a problem that the design of the mobile phone is restricted. The present invention has been made in order to solve the above-mentioned problems, and has an object to provide a mobile terminal with a mirror which is hardly damaged and has very few restrictions on the design design of the original mobile terminal. I do.

The above-mentioned usage is a method in which the display unit 3 can be used as a mirror only when the power switch of the portable terminal is turned off. Even in the case of (1), the following method is conceivable for using the display unit 3 as a mirror. For example, the power switch of the portable terminal can be switched in three stages, the first stage is a power stage, and no voltage is applied to the transparent electrode layer, so that the voltage display unit 3 can be used as a mirror. Next, 2
The stage is a power supply “contact”. As described above, a voltage is applied to the electric circuit and the transparent electrode layer of the portable terminal, and the liquid crystal mirror 5 is in a transmissive state. 4
The operation display of the mobile terminal above can be seen. The third stage of the power switch is a rebound type, and has a structure that returns to the second stage when the finger is released from the switch. When the power switch is switched to the third stage, the switch is pressed for a predetermined time or at the third stage in the circuit for applying a voltage to the electric circuit of the portable terminal and the transparent electrode layer configured in the second stage. The configuration is such that only the circuit for applying a voltage to the transparent electrode layer is turned off for a certain time, and the display unit 3 is used as a mirror. When the portable terminal receives an incoming call when the portable terminal is used in the third stage, the incoming signal is detected, and a circuit for applying a voltage to the transparent electrode layer, which has been temporarily disconnected, is provided. After recovery, a voltage is applied to the transparent electrode layer. Then, the liquid crystal mirror 5 is set to the transmission state, and the terminal liquid crystal display unit 4 is set.
The above operation display can be seen on the display unit 3.
