Abstract
A touch panel is provided. The touch panel includes a plurality of pixels, wherein each pixel includes M*N sub-pixels, at least m sub-pixels each include at least one photo sensitive area and at least one effective display area, the other n sub-pixels each include only at least one effective display area, and M≧2, N≧1, m≦M, m+n=M and m≧0. A first color filter film is disposed over a photo sensor of the photo sensitive area and a second color filter film is disposed over the effective display area, wherein the color of the first and the second color filter films are different at the at least m sub-pixels. The photo sensors at the same column are electrically connected by a signal readout line, wherein only one signal readout line is disposed at every M column of the sub-pixels.
