The industry's most power-efficient QVGA display panels will soon be available from Korean TFT-LCD maker BOE Hydis, which plans to produce a full product line of small-screen displays integrated with proprietary PenTile RGBW technology from Clairvoyante. Incorporating PenTile RGBW technology into the 1.8 to 2.0in modules will enable an optimal balance of brightness and power efficiency along with improved visual resolution.
BOE Hydis, an early adopter of PenTile Matrix technology, is continuing to support the emerging technology by building four QVGA models using PenTile RGBW layouts, including two 1.8in and two 2.0in displays.
BOE Hydis will be among the first to produce QVGA displays for mobile phones using this technology, which is ideal for mobile display panels because high brightness, low power consumption and high visual resolution are critical to usability.
BOE will build two wide-viewing angle PenTile RGBW modules using patented advanced fringe field switching (AFFS) technology to increase contrast and transmittance while limiting surface reflection, which enables easy readability and visibility under any lighting condition.
AFFS technology also provides excellent power management, and when coupled with PenTile RGBW technology can further lower power consumption.
Clairvoyante's patent-pending PenTile RGBW technology combines advanced subpixel rendering technology with an eight-subpixel configuration that adds white subpixels to the mix of conventional red, green and blue subpixels.

This reduces the number of column drivers and widens each subpixel, making a wide range of performance benefits possible.
BOE is harnessing the second-generation of this proprietary technology for the QVGA products, which are expected to be available in the first quarter of 2006.
In addition to increasing brightness and contrast ratio, PenTile RGBW also benefits the display's overall performance.
The 1.8in display modules use only three LEDs - consuming just 60% of the power that conventional LCD products would need to reproduce the same brightness at this high visual resolution.
The unique pixel arrangement increases aperture ratio and panel transmissivity.
Clairvoyante's proprietary gamut mapping algorithms improve white luminosity and contrast resulting in brighter whites and enhanced natural colours.
'One of our key objectives is to produce high-brightness, high-resolution displays for the mobile market, and we're very pleased that using PenTile RGBW technology makes that possible without increasing power requirements', says Jung Yeal Lee, Chief Technology Officer at BOE Hydis.
'Furthermore, Clairvoyante's cutting-edge approach will not only be simple to integrate into our manufacturing processes, but is a cost-efficient solution for achieving our overall goals'.
'As an early adopter of PenTile RGBW technology, BOE has long supported the PenTile value proposition and we are thrilled by BOE Hydis' continuing commitment to PenTile products', says Joel Pollack, President and Chief Executive Officer of Clairvoyante.
'We are confident their decision to build a QVGA product line based on PenTile RGBW technology will enable the AFFS-applied Viewiz products to successfully address brightness and power challenges inherent in mobile applications'.
