A liquid crystal display with consistent moving image quality regardless of viewing angles

Abstract

This paper proposes a new overdrive (OD) technology to precisely compensate for the viewing angle dependent characteristics of LCDs. This paper reports that optical response of liquid crystal displays (LCDs) is considerably dependent on viewing angles for the first time. The new OD technology applies different OD look-up tables (LUTs) depending on the viewing angles. In addition, we combine a new OD technology with an eye tracker that is usually adopted for autostereoscopic 3D LCD systems. The application results show that a new OD technology improves the motion image quality perfectly regardless of viewing angles. We expect that our proposed method will definitely enable the LCD products to have consistent motion image quality regardless of viewing angles. • This paper reports that optical response of liquid crystal displays (LCDs) are considerably dependent on viewing angles for the first time. • We propose a new overdrive (OD) technology to precisely compensate for the viewing angle dependent characteristics of LCDs. • The new OD technology applies different OD look-up tables (LUTs) depending on the viewing angles. • We also combine a new OD technology with an eye tracker that is usually adopted for autostereoscopic 3D LCD systems. • Application results show that the new OD technology improves the motion image quality perfectly regardless of viewing angles.
