Core trio boosts SoC platform
Oki Electric has enhanced its uPLAT series of integrated platforms, which lower development times of SoC LSIs, with the introduction of three core products.
More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
Oki aims to secure a 50% market share by selling 2 million units per month worldwide in the fiscal year ending March 2006.
"With higher contrast levels, wider viewing angles, faster response, lower energy consumption, and sizes that are thinner and lighter than LCDs, the self-luminous organic EL panels are attracting attention as the next generation display technology", said Akira Kamo, President of the Silicon Solutions Company at Oki Electric.
"With our specialised process for organic EL driver and the newly developed correction circuits, we succeeded in realising an extremely precise colour display of 260,000 colours".
The ML9340 series of organic EL driver ICs for mobile-phone comes in two models: the ML9340, for main panels with output of 128RGB x 80, and the ML9341, for subpanels with output of 96RGB x 96.
By using two chips, the ML9340 is able to achieve 128 x 160 dots, the current mainstream resolution level for main panels.
As both IC chips are capable of displaying up to 260,000 colours, they are optimal for displaying both still and moving images on devices such as mobile phones with cameras.
As the ML9340 series boasts onboard driver output, controller, and graphic RAM, a panel display can be realised using a single chip.
The series also helps reduce power consumption through fine-tuned power management capabilities such as partial display function, which allows for partial screen use, power-saving mode, and screen-saver function.
The use of these panels in mobile phones has increased rapidly, centred in the Asian market and practical use of such panels has begun in onboard display panels for car audio equipment.
Oki will expand its product lineup in the future in response to increasing display resolution and screen-size requirements and target sales of Y10 billion in the fiscal year ending March 2007.
