Technology paves way for non-rectangular TFT LCD modules

NEC LCD Technologies Inc. has developed a technology that enables more flexible design of TFT LCD panels. The prototype design, a "heart-shaped," low-temperature polysilicon (LTPS) color TFT LCD module formed using two half-circular arcs and two straight lines, has a display width of 4.0cm, height of 3.6cm and pixel pitch of 174?m (146 pixels per inch).

According to the company, the new technology enables optimal arrangement of gate and data lines in the pixel array and minimizes 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 2.0mm.

Moreover, the company adds that the new technology enables LCD modules to be designed with varied, more flexible shapes that can be adapted to embedded applications and to non-traditional LCD applications.
