<p>A flat panel liquid crystal display (12) with an integrated touch panel has a multitude of pixels (28) arranged in multiple columns and multiple rows. The pixels (28) of the first column (54) and last column (66), and of the first row (60) and of the last row (72) are controlled in conjunction with emitters (52, 58) and detectors (64, 70) with associated mirrors (74, 80, 82, 84) to create a sequence of light beams that extend across the display panel (12) in both the X and Y directions. Whenever a stylus (86) is placed near the display panel, two orthogonal light beams are interrupted corresponding to the X and Y positions of the stylus (86) relative to the display panel (12).</p> |
