Display technology enables widescreen expansion

Chunghwa Picture Tubes is using PenTile RGBW technology from Clairvoyante to build widescreen high-resolution display panels for next-generation mobile devices.

In response to the multimedia trends influencing emerging mobile products, Chunghwa Picture Tubes is using PenTile RGBW technology from Clairvoyante to build widescreen, high-resolution display panels that meet the needs for very bright displays and extended battery life in next-generation mobile devices.

The 4.0 and 7.0in widescreen VGA panel prototypes have been on show this week at FPD International in Yokohama, Japan.

More than half of all new notebooks on the market today have wide-aspect-ratio displays, and wide screens have become the new standard.

The pressures on small displays for video-centric applications to conform to the standards of larger displays have thus increased.

Developing widescreen panels enables CPT to meet these demands.

Furthermore, integrating PenTile RGBW technology into these panels will help solve other portable display design challenges by affording CPT's customers greater flexibility in determining an appropriate ratio of brightness to power for their product and application.

The new CPT high-brightness panels are 800 x 480 widescreen VGA, well-suited for the high-resolution, high-performance needs of today's ultra-mobile personal computers (UMPCs), personal media players (PMPs) and high-resolution portable DVD displays.

For computing applications, the widescreen format can eliminate the horizontal scrolling sometimes required when web browsing, making these panels ideal for devices enabling Internet access.

"A key factor in the success of mobile video is the availability of portable displays capable of replicating the home video-watching experience as much as possible, meaning bright, wide-format screens", according to Joel Pollack, President and CEO of Clairvoyante.

"With the integration of PenTile RGBW technology to increase luminosity of their widescreen panels, CPT is poised to capture a part of the consumer electronics market that is forecast for tremendous growth".

According to industry analyst firm IDC, the worldwide converged mobile device market will reach 181 million units by the end of 2009 and worldwide portable multimedia player shipments are expected to grow at a compound annual growth rate of 95% from 2005 to2009.

"Our partnership with Clairvoyante allows CPT to expand our range of display solutions for video-centric portable devices such as UMPCs and PMPs, thereby enabling us to enter promising emerging markets", said Kuan-Lang Wolf Chen, R and D Vice President for Chunghwa Picture Tubes.

This is the second licensing agreement between Clairvoyante and Chunghwa Picture Tubes, which previously built both 2.0 and 2.2in quarter-VGA PenTile RGBW prototypes that used only 70% of the power of the equivalent RGB stripe design.

CPT joins a growing number of display manufacturers worldwide who recognise the benefits of incorporating PenTile RGBW technology and are licensing it for their IC drivers and displays.
