NEC LCD Technologies has announced the successful development of four new system-on-glass (SOG) LCD modules (LCMs) for personal digital assistants (PDAs) and portable GPS terminals. The company said successful mass production trials began at NEC Akita on October 1.
The new modules consist of a 3.5-inch transmissive LCD, a 3.5-inch transflective LCD, a 2.7-inch transmissive type and a 2.7-inch transflective LCD. All of the new products possess the same VGA resolution. Mass production for the 3.5-inch transflective LCDs and the 2.7-inch transmissive LCDs are aimed at February, 2007.
The LCDs enable lower costs, 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. 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.
NEC said it will start to focus on SOG technology as one of its new core competences and will continue to develop and provide LCMs of high added-value while expanding the range of applications to include industrial fields as well as small-size equipment.
These four new models are displayed at FPD International 2006 in Yokohama, Japan (October 18-20).
