Moving Picture Response Time (MPRT) measurement method has discussed with several companies since 2001. The basic MPRT is designed to represent and quantify the visual perception of moving images across an AM‐LCD screen for PC monitor and TV applications. MPRT measurement method takes into account three basic LCD panel characteristics: the capacitive‐hold‐type brightness variations, brightness level dependent transition times and a liquid crystal response time including gray scales transition. This measurement system incorporates the synchronously moving some combined gray scale test patterns and the evaluation of the pattern edge brightness changes. MPRT keyword is for only liquid crystal display. But this measurement method can be used to specify new index parameter that is motion blur characteristics on each display devices (PDP, CRT and etc).

The proposed Motion Picture Response Time (MPRT) measurement is designed to represent and quantify the visual perception of moving images across an AM‐LCD screen. MPRT measurement method takes into account three basic LCD panel characteristics: the capacitive‐hold‐type brightness variations, brightness level dependent transition times and a liquid crystal response time. Further, MPRT figure is affected by a back light control method and video signal processing algorithms. The proposed measurement method incorporates the synchronously moving test pattern and the evaluation of the pattern edge brightness changes.

Abstract— The moving‐picture response time (MPRT) for measuring liquid‐crystal‐display (LCD) motion blur was studied by several organizations in 2001. To determine the LCD motion blur that humans perceive, subjective evaluation experiments using the method of adjustment was conducted to find a strong correlation between perceived motion blur and extended blurred edge time (EBET) of the MPRT measurements. MPRT thus clearly indicates the degree of which humans perceive motion blur.

15-in. XGA TFT-LCD with fast response time is developed. The response time between grayscale transitions is reduced to less than 20ms by adopting newly developed Feedforward Driving (FFD) technology. High brightness, high color saturation, and wide viewing angle characteristics are also achieved, which are significant for multimedia applications.

A new light source for laser TVs has been developed along with a 65‐inch super slim laser TV that employs the light source. In this stylish laser TV set, a depth of 255 mm has been realized owing to the new laser light source, a compact optical engine and a small laser drive power supply which are optimized to the light source.
