1. A method for enabling stylus input on a display device coupled to a computer processor, the method comprising:
- detecting, via a stylus control unit coupled with the computer processor and display device, the presence of a stylus within a display area of the display device, wherein a current video source associated with the display device is interrupted upon detection of a stylus within the display area of the display device;
displaying, via a stylus control unit, a pair of graphical image frames on the display device, wherein the pair of image frames comprises of a first image frame including a first luminescent image and a second image frame including a second luminescent image, wherein the image frames interrupt a current video source of the display;
receiving, at the stylus control unit, luminescent measurement data transmitted from the stylus; and
determining, via a stylus control unit, stylus position information based on the received luminescent measurement data.

Abstract
Embodiments of the present invention enable stylus input on a display device coupled to a processor. According to one embodiment, a stylus control unit detects the presence of a stylus within a display area of a display device and then displays a pair of frames including luminescent images on the display device. Furthermore, luminescent measurement data is transmitted from the stylus to the stylus control unit, and stylus position information is sent to a computer processor based on the received luminescent measurement data.
