Hitachi makes you say good bye to QVGA screens!
Hitachi claims their product to be industry's first 800 x 480 product as a mobile phone display panel.
Hitachi Displays, Ltd. has started mass production of 800 x 480 2.9-inch LCD panels for use in mobile phones.The panel employs the company's proprietary liquid crystal technology called IPS that boasts wide viewing angle and high image quality.
The pixel count is five times that of QVGA (240 x 320), which has been the norm for mobile phone panels.In order to boost resolution while maintaining the brightness, the luminance of the backlight unit must also be enhanced, resulting in an increase in power consumption. To solve the problem, the company has focused on the improvement of the transmittance of light from the backlight unit by revamping the pixel structure and microfabricating the wiring.
The hi-resolution 2.9" LCD panel offers wider viewing angle, better color reproduction and faster grey-to-grey response time. The new product is a transmissive LCD panel that boasts a viewing angle of over 170 degrees in both vertical and horizontal directions, contrast ratio of about 400:1 and luminance of 250 cd/m2.
