A 2D-3D Switchable Driving Method for Reducing Power Consumption of Thin-Film Transistor Liquid Crystal Display TV With Film-Type Patterned Retarder

This paper presents a new 2D-3D switchable driving method for a 3D thin-film transistor liquid crystal display (TFT-LCD) TV. The proposed driving method, which uses a film-type patterned retarder (FPR), can reduce unnecessary power consumption while displaying 2D images. The proposed driving method can change a part of a pixel according to the driving mode; the part is operated as a black matrix in a 3D display mode, whereas in a 2D display mode, the part is operated as a normal pixel. To realize the proposed driving method without increasing the data signal rates, the number of gate driver integrated circuits (ICs), and the bezel size of the panel, a novel pixel structure and an integrated a-Si:H gate driver, which can be implemented in a small size, are developed. The power consumption of the proposed driving method measured at the full white gray level is 67 W in a 47-in full-high-definition (FHD) TFT-LCD TV. This result shows that the power consumption of the proposed driving method decreases by 28% compared with that of the conventional driving method in the 2D display mode.
