Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-display type communication terminal having a two-stage folding structure,

The present invention relates to a communication terminal technology, and a multi-display type communication terminal having a two-stage folding structure can be constructed by mechanically and functionally mounting a plurality of display modules in one communication terminal and selecting multimedia information The present invention relates to a multi-display type communication terminal having a two-stage folding structure and a driving method thereof.

BACKGROUND OF THE INVENTION [0002] Liquid crystal display devices are widely used as display devices for video information and character information such as information devices typified by personal computers, portable information terminals, digital cameras, and camera-integrated VTRs, taking advantage of thinness, light weight and low power consumption.

2. Description of the Related Art In recent years, demand for low power consumption has become stronger due to the rapid spread of small-sized devices such as mobile phones and portable information terminals.

Particularly, a portable telephone or the like is provided with a screen for displaying simple information such as status information and operation information of the apparatus, apart from a screen for displaying main usage information such as communication information and contents information, Is expected to be achieved. That is, in a stand-by state such as a foldable mobile phone having a screen on two sides of the main body, only a screen with a small amount of display data, a small size and low power consumption is operated, By operating the screen of the data amount, it is possible to reduce power consumption as a whole.

2. Description of the Related Art Recently, a touch panel is mounted as a pointing device on a portable information terminal including a mobile phone or a PDA (Personal Digital Assistant). Since the intuitive operation by the user becomes possible by using the touch panel, the portable information terminal equipped with the touch panel is expected to increase in the future. Such a portable information terminal

In browsing the contents, the user designates the hyperlink displayed on the screen as a finger or a dedicated touch pen (stylus).

However, since the screen size of the portable information terminal is small, it is considered that the selection of the portable information terminal is very difficult in the portion where the hyperlinks are concentrated. For example, when the user touches the touch panel with his / her finger, the tip of the finger is struck over a plurality of links, and an unwanted link is selected. A stylus whose tip is smaller than a finger may be used. However, as the screen becomes smaller, it becomes difficult to adjust the tip to a desired position, and a selection error is more likely to occur.

In a mobile terminal, a display screen is usually composed of a liquid crystal display device (LCD), which provides a relatively good contrast ratio and color reproducibility when compared with other flat panel displays, Technological advances have demonstrated the ability to implement images that are comparable to conventional cathode ray tubes (CRTs).

Such a liquid crystal display device utilizes optical anisotropy and polarization properties of a liquid crystal. As is well known, a liquid crystal has an optical anisotropy having a long molecular structure and a directional arrangement, The orientation of the molecules is changed.

The liquid crystal display device has a structure in which a pair of transparent insulating substrates each having a field-generating electrode formed on a surface facing each other with a liquid crystal layer sandwiched therebetween and a liquid crystal alignment direction And various images are displayed by the change of light transmittance according to the artificial adjustment.

In recent years, an active matrix (hereinafter referred to as " active matrix ") in which switching elements such as thin-film transistors (TFT) (Active Matrix) liquid crystal display device has been attracting attention due to its excellent resolution and video implementation capability.

Recently, various mobile terminals have gradually integrated their functions. For example, a digital camera is mounted on a mobile phone and photographing is possible, and various functions such as movie watching or navigation using satellite are provided. However, It is impossible to find any other way than to implement a screen through a single liquid crystal display device having a display screen, which is disadvantageous in that the display screen is too narrow.
