portable terminal

technical field

The present invention relates to a portable terminal, and more specifically, the present invention provides a portable terminal that not only improves assembly efficiency of components in an LCD module, but also optimizes appearance design.

Background technique

Portable terminals are personal information terminals that are carried and used by users, including mobile phones, PDAs, and the like. Since the portable terminal is limited by portability, it is limited to a small size in appearance, but in order to perform various functions such as shooting moving pictures, it is necessary to equip the terminal with a large-screen LCD. In order to simultaneously meet the aforementioned contradictory requirements, people have developed flip-type portable terminals. However, for users of flip-type portable terminals, when confirming corresponding information, it is necessary to often open the flip. In order to avoid this kind of inconvenience for users to operate, portable terminals equipped with an auxiliary LCD on the outer surface of the flip cover appear on the market.

FIG. 1 is a front view of a conventional flip-type portable terminal.

As can be seen therefrom, the installation directions of the main LCD 11 and the sub-LCD are opposite.

Moreover, in order to ensure the transmission of control signals between the main printed circuit board in the lower flip and the LCD 11, 13 in the upper flip 10, the above-mentioned main printed circuit board and LCD 11, 13 are connected by a flexible printed circuit board (FPCB) 12. In order to connect the above-mentioned flexible printed circuit board 12 to the LCD 11, 13, a board-to-board (board to board) type connector 60 will be installed at first on the back side of the main LCD 11, and then the flexible printed circuit board 12 will be connected to the connector 60. .

But, because above-mentioned existing portable terminal machine arranges connector 60 on the back side of main LCD 11, therefore, connector 60 has taken up considerable space, makes the size and arrangement of secondary LCD 11 all subjected to bigger restriction thus , the layout space for the data lines drawn from the secondary LCD 11 is also insufficient, and when it is necessary to add devices such as cameras and speakers to the body, it is necessary to use larger-sized connectors. Therefore, the assembly efficiency of the main LCD parts of the existing portable terminal is relatively low.

Contents of the invention

In order to solve the above problems, the purpose of the present invention is to provide a portable terminal that improves the assembly efficiency of components in the LCD module and also optimizes the appearance design.

In order to achieve the above object, the present invention provides a flip-type portable terminal with a lower flip and an upper flip connected to the lower flip through a first hinge portion, the terminal further includes: a main body connected to the lower flip at one end The printed circuit board is connected, and the other end is connected with the main printed circuit board arranged on the upper flip cover; the second flexible printed circuit board connected with the main LCD of the upper flip cover; installed on the above-mentioned main LCD side, and connect the first flexible printed circuit board with one end of the second flexible printed circuit board, for connecting the connector of the printed circuit board, etc.

Wherein, the above-mentioned second flexible printed circuit board for connecting to the LCD is preferably installed at the back of the above-mentioned LCD and bent vertically downward.

Moreover, in order to fix the above-mentioned first flexible printed circuit board, a guiding part is preferably arranged on the above-mentioned flip cover, so that the effect will be better.

As described above, according to the embodiments of the present invention, the following various effects can be obtained. It should be noted that the present invention cannot be established when all the following effects are produced.

First of all, in the present invention, since the flexible printed circuit board connection structure of the portable terminal is arranged on the side of the LCD with considerable spare space, the arrangement and size of the sub-LCD can be freely adjusted, which is conducive to optimizing the appearance design.

Secondly, when devices such as cameras and speakers are added to the body, even if a larger-sized connector for connecting the printed circuit board is used, it will not affect the installation of components in the LCD.

Finally, the guide part can prevent disconnection and wear caused by the flexible printed circuit board used to connect to the main printed circuit board coming into contact with other components such as LCDs.
