Abstract: A method for sharing notes of an electronic book (E-book) is illustrated. The method includes steps of: comparing an identification information of a note file with a book information of the electronic book for determining whether the note file corresponds to the electronic book; receiving and transferring the note file to an electronic reader displaying the electronic book when the note file corresponds to the electronic book; stacking and displaying at least one note layer included in the note file above an electronic page of electronic book displayed on a user interface of the electronic reader, wherein the note layer includes an auxiliary annotation associated with content of the electronic page and the note layer is independent of the electronic page. Therefore, reader may read the E-book and review related annotations on the user interface at the same time, and share the note file independently to other readers.

Abstract: A touch display device includes a display panel, a touch panel, a trigger module and a control module. The touch panel has a sensing area equivalent to the maximum display area of the display panel. The sensing area detects a touch event occurring thereon in order to generate a touch instruction. The control module executes the touch instruction and generates a display signal to drive the display panel to display images in the current display area which is not greater than the maximum display area. When the trigger module generates a trigger signal, the control module reduces the current display area to form a blank region in at least one side of the current display area. Accordingly, the touch event occurring on the blank region generates an invalid touch instruction.
