Description

Mobile terminal with multi display structure

The present invention relates to a portable terminal having a multi-display structure, and more particularly, a folder type portable terminal provided with a pair of input parts folded around a hinge axis and a pair of screen display parts sliding upward from the front of the input part. The present invention relates to a portable terminal having a multi-display structure having excellent durability and excellent expandability of various multimedia.

Generally speaking, a mobile terminal is a mobile communication terminal such as a digital phone, a cellular phone, a PCS phone, or a personal digital assistant, a smart phone, a small notebook, and the like. As a portable digital terminal, a device which is generally linked with a wireless communication link performs a function of providing various digital contents such as voice and video information to a user.

Due to the development of the technology, such a portable terminal provides a user with text information, image information, a game, etc. beyond the step of delivering only simple voice information. The types of the mobile terminal are largely bar type, flip type, It can be divided into folder type and slide type.

Folder and slide-type mobile phones have different characteristics in terms of their functional aspects and ease of use, and therefore, there are advantages and disadvantages to selecting and using any one of them. For example, the folder type is advantageous in terms of phone function and durability, but the slide type portable terminal is advantageous in terms of multimedia function and design.

Recently, in order to satisfy various needs of consumers, Published Patent Publication No. 10-2005-0060827 capable of converting a display unit into a folder or a slide type according to a user's taste has been introduced. There is a problem that the slide switching structure is relatively complicated, and the coupling structure of the display unit is unstable.

In addition, in order to maximize portability, the size of a conventional display panel is very limited due to the characteristics of a portable terminal for miniaturization and light weight, and thus there is a problem in that high-quality image contents cannot be displayed.
