NEC LCD Technologies Develops Four New System-on-Glass LCD Modules

NEC LCD Technologies, Ltd. today announced the successful development of four new system-on-glass (SOG) liquid crystal display (LCD) modules, suitable for personal digital assistants (PDAs) and portable GPS terminals. Successful mass production trials for low temperature poly-silicon (LTPS) thin-film-transistor (TFT) color liquid crystal display modules began at NEC Akita, Ltd. on October 1. The new system- on-glass (SOG) liquid crystal display (LCD) modules consist of a 3.5-inch (8.9-centimeters-diagonal) transmissive type LCD, a 3.5-inch transflective type LCD, a 2.7-inch (6.8-centimeters-diagonal) transmissive type LCD and a 2.7-inch transflective type LCD. All of the new products possess the same resolution as video graphics array (VGA) TFT LCD modules. Mass production for the 3.5-inch transflective LCDs and the 2.7-inch transmissive LCDs are aimed at February, All four new LCD models have been developed for display devices of PDAs and portable GPS terminals.

They achieve cost reduction, faster time to market and downsizing of instrumentation through a reduction in the number of instrumentation parts built into the new SOG LCD by integration of peripheral circuitry on the glass substrate of the TFT LCD. In addition, they possess a function for displaying 16.19 million colors by a built-in step interpolation circuit, boast a switching VGA/QVGA display, and are equipped with a touch panel.
