Sanyo has disclosed that it employed a vertical alignment (VA) mode LCD panel for its 37-inch LCD TV product announced on August 23.
Sanyo explained that the reason for having chosen the VA mode panel was its "highest class
performance," compared to in-plane switching (IPS) mode panels broadly used in its current
LCD TV products.
The company paid its most attention to the luminance when choosing a panel to be used in the
37-inch LCD TV. The abovementioned VA mode panel boasts a front face luminance of 550 cd/m2,
compared to "around 500 cd/m2" achieved by IPS mode panels. However, what became a decisive
factor behind the choice was the panel's response speed, which was sharply reduced to 6 ms.
According to Sanyo, most current LCD panels need 15-16 ms to respond. The up/down and
left-right viewing angles at a JEITA-based contrast ratio of 10:1 are both 176 degrees,
which the company claims "are sufficient values." Sanyo procures the 37-inch LCD panels from
an outside company, whose name has not been specified, but based on the panel
specifications, Chi Mei Optoelectronics Corp. of Taiwan is supposed to be the manufacturer.
