South Korea-based TFT-LCD maker Boe Hydis Technology claims to have developed a mobile phone LCD that doubles display brightness without changing power consumption levels. The LCD panel is a 2-inch quarter video graphics array (QVGA) display, with a brightness of 300 cd/m2, a contrast ratio of 500:1, and color representation of 45 percent.

The company says it has used a sub-pixel rendering technology to enhance the brightness and transmission of the LCD by twofold. Boe Hydis added white to the conventional RGB (Red/Green/Blue) florescent substance in order to create an RGBW structure. In addition, an amorphous-silicon row driver (ARD), a gate drive IC built onto an LCD board, completed the display.

Boe Hydis expects the technology adapted to high-resolution, small-sized VGA TFT-LCD panels through application of the amorphous silicon (a-Si) technology without the requirement of additional facility investment.

"The brightness and slimness of these LCD panels with the combination of lower required power surpasses all other existing ones. These advantages will increase the product's market competitiveness; not to mention the benefit of reduced costs. In the future, we are planning to apply the panel to high-end mobile phone products like DMB phones, high resolution camera phones, and PMP displays," stated Jung Yeal Lee, head of the R&D center at Boe Hydis.
