Sony announces 3.0-inch LED backlit 921K LCD
Sony introduces the ACX396AKS LCD module, a 3-inch LED backlit LCD that uses low-temperature polysilicon transistors. The panel features ultrahigh resolution (271 ppi) and through its Window-On antireflection process technology it can display strong blacks and increases display visibility. In traditional LCD panel structures there are large losses due to reflections in the air gap between the protective cover and the LCD module. By directly applying the protective cover to the LCD, the loss from reflections can be reduced significantly…
HIGHLIGHTS
More about LED backlight technology at WikipediaThe ACX396AKS is a built-in driver diagonal 7.5 cm LED backlit Window-On module that uses low-temperature polysilicon transistors.
This panel features ultrahigh resolution (271 ppi) and provides a detailed and smooth display. Furthermore, by adopting the Window-On antireflection process technology, the ACX396AKS can display strong blacks and increases display visibility.
â– Visibility increased by the Window-On antireflection process technology
■VSPECIIITM (wide viewing angle technology) achieves the wide viewing angle of 160° in the up/down and right/left directions (CR 100:1)
â– Wide color gamut: sRGB 100%
â– New LCD mode adopted Contrast: 800:1
â– Number of display dots: 921k dots in an 7.5 cm (3.0″) stripe arrangement panel
Window-On (Antireflection Process Technology) Adopted
In existing LCD panel structures there are large losses due to reflections in the air gap between the end product’s protective cover (window) and the LCD module. The ACX396AKS, however, adopts the Window-On antireflection process technology.
By directly applying the customer’s protective cover (window) to the LCD, the loss from reflections can be reduced greatly and the display’s visibility can be increased. As compared to a reflectivity of 12% when there is an air gap, the reflectivity is reduced to 4% when there is no gap. (See figure 2.)
VSPECIIITM (Wide Viewing Angle Technology) Adopted
This device adopts a wide viewing angle mode based on Sony’s new VSPECIIITM technology. Visibility is increased at every viewing position and the panel achieves a viewing angle of 160° in the up/down and right/left directions.
Wide Color Gamut
Due to adoption of the new VSPECIII TM wide viewing angle mode, the ACX396AKS achieves the wide color gamut of sRGB 100% (NTSC 74%). (See figure 4.)
High Contrast
The ACX396AKS achieves the high contrast of 800:1 by adopting the VSPECIIITM wide viewing angle LCD mode.
Finer Detail
Due to its ultrahigh resolution (271 ppi), the ACX396AKS produces smooth and detailed images. The number of pixels displayed is 640H × 3 × 480V, or 921,600 dots.
