New Substrate Tech Creates System LCDs

smartalix writes "Sharp Microelectronics has recently developed a new LCD substrate technology called Continuous-Grain Silicon (CG-Silicon), that enables device integration on a scale previously impossible. The technology enables the creation of System LCDs that integrate all driver and operation circuitry -- including digital logic, LCD driver, power supply, I/O interfaces, and signal-processing circuitry -- onto the glass itself. Eventually even the device's CPU will be included on the substrate. A key SLCD feature is the ability to dynamically control the resolution and color depth, providing output in multiple-resolution modes while lowering overall power consumption. A 3.7-in. SLCD created with CG-Silicon had a power consumption of 14 mW for color VGA, 8 mW for color QVGA, and 2 mW for monochrome QVGA. The first commercially available product that incorporates the System LCD architecture is Sharp's Zaurus SL-C700 PDA, recently released in Japan."

    As much as I love trusting the poster to have not made up a news story...here is the actual press release.

    QVGA

    QVGA is an emerging standard for Palm Powered devices. Traditionally, Palm Powered devices have featured 160 x 160 pixel screens. QVGA screens feature a resolution of 240 x 320 pixels. The QVGA standard was originally adopted for the HandEra 330. New products with built-in QVGA technology are anticipated within the coming year.

    QVGA-aware applications include support for a high-resolution bitmaps, additional fonts, and a collapsible 'virtual' graffiti area. Optionally, they can also support landscape and portrait screen rotation.

  4. More info on power consumption by hobbs · · Score: 5, Informative
    Wanting more info on this, I found: Sharp Slashes LCD Power Consumption which is from Feb 2001 and appears to be an announcement of the tech. I really wanted to know the relative power consumption (since my e740 pocketpc sucks power), and this articles says:
    Compared to a conventional active-matrix display, which is refreshed between 60 and 70 times per second, the ULC (ultra-low-power consumption) technology only sends signals when the screen image is changed. This results in a drop in power consumption to one-third conventional levels for moving images and one-thirtieth for still images
