PURPOSE: A touch panel system is provided to embody a slim touch panel and to maintain recognition efficiency by effectively inducing the optical source of a light emitting module to a recognition surface. CONSTITUTION: A light emitting module(120) includes optical sources in which are located on a flat surface and a screen structure(110). A lighting bar(140) includes a diffusion material which induces the light of the optical source to move to a recognition surface(130). A capturing module recognizes a touch signal in which is offered to the screen structure. The lighting bar is constituted by a transparent material by including an input unit and an output unit. The lighting bar is projected to the recognition surface in order to induce the light to be emitted to the recognition surface through the input unit and the output unit.
