REVERSIBLE AND REMOVABLE DISPLAY APPARATUS FOR TERMINAL}

The present invention relates to a reversible display device of a terminal, and in particular, after the conventional one side rotary display device is removed, the front and rear sides of the display can be inserted again. Or, as the car navigation system (car navigation system) is widely used, in some cases it is related to a reverse removable display device of the terminal to solve only the need to turn over the display device, or sometimes removable products have emerged.

Conventional display devices, such as portable DVD players and notebook PCs, can be opened and closed at appropriate angles. Recently, car-mounted AV players or car navigation systems are widely used. As a result, there is a need for a product that can only be flipped or sometimes detached from the display device.

Conventional products are inconvenient because they require a lot of free space when opening and closing due to space constraints in the car, and can only be seen from a certain angle. In the case of laptops, for example, they simply opened and closed in a rotary manner, but demand for display units such as LCDs (liquid crystal monitors) that were bent at various angles increased rapidly.

In recent years, with the rapid growth of the multimedia environment and the information age, the demand for miniaturization, high performance, as well as portability and versatility of storage and display devices continues to grow.

In light of this trend, demands for high functionality of portable display devices, diversification of applications, portability, and the like are exploding.

In other words, it is necessary to use portable devices such as portable DVD players, notebook PCs, PDAs, etc., which are generally used as portable devices, as a display device for car navigation, or to enjoy movies or music videos in connection with car DVDs. It is increasing.

In addition, when using the screen display device in a narrow place, such as a car, airplane, train, etc., it is also necessary to adjust the angle of the display unit that is not restricted by space.

It can be opened at an appropriate angle by using the structure, and the angle opened by the friction load of the friction mechanism is maintained. However, this method has a limit in the opening angle of the display panel 110.

The terminal illustrated in FIG. 16 allows the display panel 110 to be adjusted to an angle using a support hinge 120 having a biaxial hinge on the portable terminal main body 100.

The terminal shown in FIG. 17 is known from Japanese Laid-Open Patent Publication No. 2002-23650 (P2002-23650A), and the display panel 110 has a support-type hinge 130 having a biaxial hinge on the portable terminal body 100. Use it to adjust the angle, so that only the monitor can be pulled up in that state, it is intended for ease of use in narrow airplane, rail travel.

However, despite such many development efforts, there are still many limitations in using the display device and many inconveniences in using the display device require continuous research and development.

The present invention has been made to solve the above problems and defects as described above, to improve the inconvenience of space utilization due to the rotary opening and closing structure which is a problem of the prior art described above.

Another object of the present invention is to enable the display unit to be used upside down.

Also, the display unit can be separated and used in other devices.
