NEC LCD Technologies Ltd, along with its sales and marketing channels in Europe and the Americas, NEC Electronics Europe and NEC Electronics America Inc, have announced the development of a color TFT LCD module that enables the viewing angle to be switched from wide to narrow in accordance with display contents, use and application of the LCD.

NEC LCD Technologies has realized the LCD module by its own value integrated TFT-LCD (VIT) technology, along with the addition of a new viewing angle-switching control on the polarizer adjacent to the backlight system. The angle-switching control enables the light from the backlight system to be switched from a diffused pattern to a straight pattern by control signals, allowing easy switching of the viewing angle mode from that of wide to narrow.

The LCD devices address two divergent needs -- secure viewing of personal information achieved by a narrow angle mode, and broad viewing of public information realized by a wide angle mode. Various new technologies have been introduced to address this need; however, none fully enables the secure viewing of personal information while also allowing broad display of public information.

NEC LCD Technologies exhibits the LCD panel at FPD International 2007 in Yokohama City, Japan.
