Samsung Electronics says it has developed a liquid crystal display (LCD) visible almost side-on thanks to its mSWV+ and half mirror technologies. The company applied a technology called Patterned-ITO Vertical Alignment (S-PVA) on small and middle-sized LCD panels to achieve a 160 degree viewing angle.
Samsung said Sunday the screen can also be seen under strong sunlight without backlight. Energy consumption is low. Conventional permeable LCDs have a contrast ratio of 250:1, and a vertical viewing angle of 80 degrees and a horizontal viewing angle of 100, but half-mirror LCDs have a contrast ratio of over 400:1, and vertical and horizontal viewing angles of 160 degrees.
The company said when the technology is applied to small and middle-sized displays, it will allow users to watch digital multimedia broadcasting (DMB) terminals or game phones both indoors and out.
Samsung plans to first apply the technology in panels for advanced mobile phones and start mass-producing them in 2006. It will expand application to audiovisual products such as portable multimedia players and car navigation systems.
