| NEC Develops Flexible TFT LCD Technology | |||

NEC LCD Technologies' new technology enables optimal arrangement of gate and data lines in the pixel array and minimises the overlaps between gate and data driver circuitry, when the module is non-rectangular in shape. By applying its proprietary value-integrated TFT (VIT) technology and integrating the driver circuits into the module along the perimeter of the LCD glass, NEC LCD Technologies has simplified the interconnection scheme and substantially reduced the area needed to contain the wiring and interconnections between external circuits, thereby yielding a bezel as slim as 2.0 mm.
Traditional display modules are rectangular in shape, since it is the simplest, most efficient and versatile shape for accommodating the pixel arrays. Recently, LCD suppliers have started to introduce fairly simple non-rectangular LCD shapes, including circles, ellipses and rectangles with trimmed corners.
The shapes have been fairly simple because the more complex the shape, the more difficult it is to accommodate the wiring patterns, resulting in thicker bezels and greater consumption of power. Displays with non-rectangular shapes are generally targeted to replace mechanical instrument gauges-such as the speedometers and tachometers found in cars-and other applications that require simple shapes.
NEC LCD Technologies' new technology enables LCD modules to be designed with varied, more flexible shapes that can be adapted to embedded applications and also to non-traditional LCD applications. NEC LCD Technologies believes this development will stimulate the development of new and unique LCD applications.
