Abstract

A tablet personal computer having functions of switching keyboards and display data comprises the following elements. A touch liquid crystal display has a function of receiving input signals from an electronic pen. A motherboard is electrically connected to the touch liquid crystal display. A switched keyboard key-in module serves for displaying a virtual keyboard layout on the touch liquid crystal display so as to key-in data by using an electronic pen or by typewriting by fingers; and for transferring the display content of the touch liquid crystal display from a wireless AV signals transmitting device to a wireless AV signals receiving device. The wireless AV signals transmitting device serves for receiving the display contents of the touch liquid crystal display and transmitting the display content wirelessly; and the wireless AV signals receiving device serves to receive the wireless signals and transfer the display content to a large scale of display.

Claims

1. A tablet personal computer having functions of switching keyboards and display data comprising:

a touch liquid crystal display having a function of receiving input signals from an electronic pen;

a motherboard electrically connected to the touch liquid crystal display;
