By the way, early LCD TVs used a high haze surface treatment with a haze value of 40 %. At that time, those films were made mainly by sputtering or vapor deposition of antireflective coatings, but the deposition of large areas is difficult and very expensive, and their use for televisions was impossible. Therefore, the real contrast in a bright room had been a problem, but in order to minimize the reflection of the surface, the design concept similar to the module for office automation (OA) had been incorporated. So, in 1999 Sharp Corp. announced low-reflection black TFT for medium-sized LCD modules, which combined LR and AG properties and had a haze value of 20 % or less. As the leader of the production unit, I... 

By using an LGP in an edge-lit BLU one can obtain a thin BLU with high luminance uniformity than the direct-view BLU. In the early period of LCD panel the direct-view BLUs were used. However, the demand for thinner structures boosted the usage of LGP, i.e., the edge-lit type. Currently the mainstream of the BLU for LCDs is the edge-lit type, and direct-view type is used in large sizes.

In practical devices, just as in the case of the varistor, Nm is usually limited by the capacitance of the diode, rather than by its static behavior. An evaluation of the diode shows that its minimum size is set by lithography, rather than by current density considerations. A small (2 X 2-jim) back-to-back diode, fabricated in a 5000-A-thick amorphous Si film has a capacitance in the order of 10-3 pF. The impedance of this capacitance limits the maximum number of lines that can be addressed. It appears that large displays, several hundred lines, can be addressed since the typical capacitance of a 1 X 1-mm LCD cell is about 10 pF.
