Abstract

This work investigates the characteristics and optical responses of photo thin-film transistors (TFTs) that are covered with color filters in the three primary colors. The transmission rates of the color filters under the illumination with various wavelengths are presented as a reference for the integration of photo TFTs with conventional color filters. Measurements are made on previously developed white-light photocurrent gating (WPCG) structures with compensating photo TFTs with different aspect ratios to examine the driving capabilities of three photo TFTs. Favorable values of parameters of the applied WPCG structures that yield similar responses are established from the measured outputs of the structures, benefiting the integration of optical input functions with the three primary color optical input signals for large TFT-LCD panels.
