Title: Portable computer and method using an auxilliary LCD panel having a touch screen as a pointing device

Abstract: A portable computer includes a main LCD panel hingedly coupled to a system body, and an auxiliary LCD panel mounted upon the system body. A video image is identically displayed on both the main LCD panel and the auxiliary LCD panel. Alternatively, a definition of the auxiliary LCD panel is lower than that of the main LCD panel. Although a user cannot look at a screen of the main LCD panel, the user can confirm a position of a pointer through a screen of the auxiliary LCD panel. Therefore, the user can precisely control the pointer using a touch screen.
