18.1: Distinguished Paper: Novel TFT‐LCD Technology for Motion Blur Reduction Using 120Hz Driving with McFi

Abstract

Samsung has launched a 70-inch Full HD (1920X1080) LCD-TV panel which, on a commercial basis, is the world's largest size so far. This size is the maximum that can be achieved using a single polarizer sheet. Its features include 600 nits luminance, dynamic control using LED local dimming, 100,000:1 contrast ratio, and a color gamut of 105%. Also, it is the world's first high speed FHD 120Hz frame rate panel, accompanied by a newly developed pixel structure and driving scheme. This totally new driving method concept includes an alternative pixel structure developed from the 1G-2D cell structure that we announced last year. Also, new product and design technology, optimized for larger sized LCD-TV products, was adopted. This technology overcomes severe charging margin requirements, enabling manufacturability and high quality in 46", 52", 57", 70").

Evaluation of conductivity and moisture content of eggs during storage by using transformer method

“…The frequencies selected include those allocated for industrial, scientific and electrical applications in extreme low frequency ranges at 50, 120, 200 and 400 Hz. (Falone et al, 2008;Kim et al, 2007;Ellenrieder et al, 2013;Caricchi et al, 1998).…”

On-time modulation for liquid crystal displays with insufficient charging time

“…But, the vertical crosstalk is a severe problem. 3 Therefore, a two-line inversion with the OTM should be applied to overcome the crosstalk and insufficient line time. In conclusion, I believe that the OTM can definitely contribute to the success of 120-Hz driving for premium LCD-TVs with higher image qualities.…”

Technical evolution of liquid crystal displays

“…Th e other method, known as the high refresh rate method [60,61], reduces blurring without introducing flicker or reducing luminance or contrast by multiplying the frame frequency and inserting one or more interpolated images between successive frames (Figure 6(c)). Th is method is widely used in commercial displays.…”

“…In VA-mode panels, a very dark state can be achieved because there is no residual retardation in the fi eld-off state [61]. Th e micrometerhigh protrusions in MVA-mode cells could cause light leakage due to the slight tilting of the LC molecules.…”

“…Backlight-dimming technology, originally developed to enhance the dynamic contrast ratio, also reduces power consumption [61,77,78]. Th e backlight luminance in this case is varied according to the maximum gray level of the displayed image.…”
