BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal having a laser projection display, and more particularly, to a screen of a portable terminal having a laser projection display including a screen unit which rotates in a terminal having a laser projection display and slides in both directions. Relates to a device.

In general, it is multifunctional according to the needs of consumers recently, and its size is miniaturized, and among the multifunctionals, it is possible to download MP3 music by accessing voice communication, radio listening, and the Internet. With digitization, it can be easily obtained from portable terminals, PDAs, computers and notebooks.

In addition, the data output device of the portable terminal commonly uses a display unit (LCD). Basically, the keypad used for data input consists of an arrangement of a plurality of keys.

Such a portable terminal has a bar type terminal in which a communication device, an input device, an output device, etc. are installed in one housing, a flip type terminal in which a flip cover is rotatably installed in the bar type terminal, and a pair of housings are separated from each other. It is classified into a folder type terminal and the like installed to be rotatable in an adjacent direction. In particular, the folder type terminal is easy to carry by folding a pair of housings, and when a pair of housings are used apart from each other when talking, the portable terminal occupies the mainstream of the portable terminal market because of its portability and convenience. Recently, sliding type and swing type terminals have appeared in the portable terminal market to satisfy various tastes of users.

On the other hand, mobile communication services have been initially limited to voice calls and short message transmission.However, with the development of mobile communication technology, on-demand video, music video, movie / music file playback, TV watching, games, mobile banking, etc. The trend is expanding to various service areas.

However, in order to enjoy on-demand video, music video, movie / music file playback, TV viewing multimedia services, it is essential to see the screen displayed through the display unit.

In addition, as shown in FIG. 1, a laser projection display 2 (LPD) is mounted on a conventional portable terminal 1, and the terminal 1 is connected to the terminal 1 by light rays projected from the laser projection display 2. Although viewed through the provided display unit 3 (LCD). Since the laser projection display and the display unit for the terminal must be provided in the terminal, a mounting space is required separately in the terminal, thereby increasing the thickness of the terminal and causing a reduction in miniaturization and slimming.

In addition, the laser projection display has a limitation in viewing a small screen when multiple people watch together because the image should be viewed only by the display unit fixed to the terminal.

Accordingly, the present invention is to solve the above-mentioned conventional problems, an object of the present invention, by rotating in a terminal having a laser projection display and by forming a screen portion extending by sliding movement in both directions, laser projection The present invention provides a screen device of a mobile terminal having a laser projection display that projects light rays of a display onto a large screen so that an image can be viewed through the most optimized and wide screen.
