摘要：<p>PURPOSE: A touch screen device is provided to detect a location using light flux emitted fro a light pen or a digital pen. CONSTITUTION: The first and second light detecting devices(110,210) are arranged in both ends of the first light wave guides. The first and second light detecting devices detect the X-axis coordinate of light flux combined with the first light waveguide by a structure. The third and fourth light detecting devices(310,410) are arranged in both ends of the second light waveguides. The third and fourth light detecting devices detect the Y-axis coordinate of light flux combined with the second light waveguide by the structure.</p>
