26.2: Motion‐Adaptive Alternating Gamma Drive for Flicker‐Free Motion‐Blur Reduction in 100/120 Hz LCD‐TV

Abstract

LCD motion blur is a well‐known phenomenon and several approaches have been developed to address it. This includes very high performing approaches based on Motion‐Compensated Frame‐Rate‐Conversion (MC‐FRC) and very low cost approaches based on impulsive driving. Impulsive driving schemes are attractive because of their low cost but suffer from two significant issues — loss of luminance and large area flicker. We propose a new impulsive driving approach using Motion‐Adaptive Alternate Gamma Driving (MA‐AGD) which removes motion blur and preserves the original luminance level without causing large area flicker.

Effects of Carbon Nanotube Length on Electro-Optical Characteristics in Liquid Crystal Cell Driven by Fringe Field Switching

“…To improve this moving picture performance, various methods such as backlight scanning technology [1,2], increase in frame rates from 60 Hz to 120 or 240 Hz [3,4], and physical property improvement of liquid crystal (LC) mixture [5,6] were proposed and studied. Since LCD-television starts adopting high frame rates, the development of LC mixture which exhibits faster response time becomes more important.…”

13.2: Optimization of Electrode Shapes for High Performance Optically Isotropic Liquid Crystal Display

“…However, response time of rod-like shape LC with nematic phase has intrinsic limitation. To improve the response time of LCD and display better moving pictures, many efforts have been done such as overdriving [1][2] technology and increasing the frame rates from 60 Hz to 120, 240 or even 480 Hz [3][4]. However, these approaches increase production cost.…”
