Abstract
A color scan array for linear imaging employing a matrix of photo-sensor and thin-film transistor (TFT) elements aligned in parallel rows with each row representing the same color and sub-pixels of a linear array of pixels. The rows of sub-pixels are sub-divided into groups, with the TFT of each color group commonly connected to a data line, and with plural gate lines provided each connected to the corresponding TFTs of the sub-pixels of each group pixel. The result is a short, compact sensor with a relatively small number of crossings and thus reduced capacitance and increased responsivity.
