Subject: More prior art for Microsoft ClearType technology

Here are some more references to possible prior art for the Microsoft
ClearType technology that we discussed on this list three weeks ago:

                 for a gray-scale thin-film-transistor (TFT) -driven
                 twisted nematic (TN) liquid crystal display (LCD) is
                 discussed in terms of display legibility and ease of
                 fabrication. To optimize cell design for gray-scale
                 application, some key display factors such as contrast
                 ratio, color change, and viewing cone are evaluated for
                 various cell geometries and cell thicknesses. The cell
                 geometries discussed are combinations of two display
                 modes (a normally white mode and a normally black mode)
                 and two optical eigenmodes. A new driving scheme of
                 threshold-voltage bias application to the LC cell is
                 proposed to overcome the TN LCD shortcoming of a narrow
                 viewing cone. The authors have adopted a cell design
                 for a 512-color TFT LCD: (1) a first minimum normally
                 white (NW) mode as polarizer arrangement for ease of
                 fabrication, (2) an extraordinary-ray mode (e-mode) as
                 optical eigenmode with a novel driving scheme
                 (threshold-voltage biased) for gray-scale improvement
                 in eliminating brightness reversals, and (3) a
                 retardation (d Delta n) value of 0.47$\mu$m for further
                 optimization of proper gray-scale order and color
