Slide phone with dual display

The present invention relates to a slide phone, and more particularly to a slide phone having a dual display.

In general, in the case of a clamshell mobile phone, the main display is provided on the inside of the cover, so the user needs to open a folder to check the information through the main display. In order to solve such inconvenience, the sub display shows simple information even when the folder is folded. The display is additionally installed. On the other hand, since the main display is always exposed on the surface of the slide phone, the information displayed on the display can be checked without opening the cover, so there is less need for a separate sub display.

Recently, however, a large number of mobile phones equipped with digital cameras have been released to enable processing of various image information captured by digital cameras unlike in the prior art. In particular, when shooting in the 'self-camera' mode, the focus and zoom status are real-time. The demand for the preview function, which is clearly visible, is prominent. In general, in the case of a slide phone where the camera is installed on the opposite side of the main display, the need for additional mounting of the display on the same side as the camera is increased. Doing.

In addition, a mobile phone using a VGA-type folding camera module structure has been released, but as the camera module develops in megapixel units, it becomes bulky, so the folding camera structure is not suitable for a megapixel camera phone.

As a related art of a mobile phone equipped with a dual display, first, Korean Patent Application Publication No. 10-2004-0049938 ('Dual LCD Mobile Phone') may be mentioned. According to the present invention, a folder having a main LCD and a sub-folder having a sub-LCD are coupled to a hinge device in a folder-type mobile phone having a dual LCD so that the sub-LCD is rotated by a user's operation and located outside the main body. You can check the sub LCD without opening it. However, the present invention is based on a foldable mobile phone, and has a limitation in that there is no function to specifically control the image information acquired by the camera, and the sub LCD can be formed because the cover is provided with the main and sub LCD simultaneously. There is a problem that the size of is limited.

Second, the Republic of Korea Registered Utility Model Publication No. 20-0333934 ('mobile phone having a dual LCD screen'). The present invention relates to a mobile phone having dual LCD screens having two LCD screens mounted on the top and bottom of the mobile phone main body, so that various mobile phone services can be used through the two LCD screens. However, the above invention is based on the premise of a folding mobile phone, and there is a limitation in that there is no function to specifically control the image information acquired by the camera.

That is, in the case of a slide phone, there is an advantage in that information displayed on the main display can be checked without opening a cover. In the case of a slide phone equipped with a camera, a preview function can be secured by adding a separate sub display. In addition to the functions of the conventional dual-fold mobile phone, by controlling the image information respectively displayed on the main display and the sub display, it becomes possible to use more various functions and services.

The present invention has been made to solve the above problems, an object of the present invention is to provide a slide phone having a dual display with a main display and a sub display on the premise of the slide phone.

Another object of the present invention is to make it possible to display different image information such that image information acquired by the camera is simultaneously implemented on the main display and the sub-display, or real and processed images are respectively displayed on the main display and the sub-display.
