  • Publication number: 20120169604
    Abstract: A method for preventing mis-touch of a touch keyboard includes triggering a timer when the touch keyboard is touched. A key code corresponding to the touched position is obtained and stored in a storage unit. When the touched position discontinues being touched, the timer is stopped and a touched time of the touch keyboard is obtained from the timer. The touched time is compared with a touched-time upper bound. If the touched time is less than the touched-time upper bound, the stored key code is output.

  • Publication number: 20120146912
    Abstract: A method for adjusting a display appearance of a keyboard layout displayed on a touch display unit includes the steps of: (A) detecting a first touch press at a start datum point of the touch display unit; (B) detecting a second touch press at a first position different from the start datum point; (C) detecting a motion track on the touch display unit; (D) computing a key pitch and a key size parameter of the keyboard layout, based on a relative position relationship between the start datum point and the first position; (E) computing a curvature and a curving mode of the keyboard layout, based on a shifting direction and a shifting distance of the motion track; and (F) adjusting a display appearance of the keyboard layout, based on the key pitch, the key size parameter, the curvature, and the curving mode.

  • Publication number: 20100103348
    Abstract: A display including a display panel, a transparent rear plate, a backlight module, and a first optical film set is provided. The transparent rear plate has a first surface, a second surface, and an optical decoration. The first surface is facing the display panel, and the second surface is relatively far away from the display panel. The optical decoration is located on at least one of the first and second surfaces. The backlight module is disposed between the display panel and the transparent rear plate. The first optical film set is disposed between the backlight module and the transparent rear plate. Combination of the optical decoration, the backlight module, and the first optical film set forms a plurality of images which can be displayed on the second surface of the transparent rear plate.
