Optical touch panel structure

The invention discloses an optical touch panel structure, comprising a color filter substrate with multiple pixel units and a thin film transistor substrate, wherein each pixel unit is composed of a red block, a green block and a blue block; the thin film transistor substrate is provided with multiple photo-sensitive cells corresponding to the pixel units; the non-photo-sensitive areas corresponding to the photo-sensitive cells on the pixel units are provided with a black matrix respectively; the black matrixes are configured on the red block or the green block or the blue block so as to adjust the aperture opening ratio of the red block, the green block and the blue block by utilizing the occupied area of the black matrix on each block and enable the deviations of brightness and color to reach a balance point respectively, thus minimizing the color deviation and brightness loss.
