Panasonic Corporation has developed a 20-inch 4K2K (3,840
x 2,160 resolution, approx. 8.29million pixels) IPS Alpha
LCD panel. The new panel boasts world's highest pixel density
of 216 pixels per inch (ppi) and the world's thinnest measuring
3.5 mm. The prototype panel is on show at the 2012 International
CES.
The 4K2K IPS Alpha LCD panel employs two new technologies,
"Pixel structure with ultra-high aperture ration structure"
and "New liquid-crystal molecular orientation process
technology".
These Panasonic's new technologies enable viewers to enjoy,
from any angle, ultra-high definition videos that show fine
lines and texts crisp and clear on the screen and faithfully
reproduce lifelike images with subtle textures and even
a sense of depth.
Panasonic's explanations on these technologies:
(1) Pixel structure with ultra-high aperture ratio
Panasonic has developed a new pixel structure that significantly
reduces the effects of the electric field that are generated
due to the increase in pixel density, and improves IPS Alpha
panel's already industry-leading light transmission rate
approximately twice as much as the panels having the conventional
structures*8.
(2) New liquid-crystal molecular orientation process technology
The orientation performance of the liquid crystals in a
plane parallel to the TFT (Thin Film Transistor) substrate
is further improved.
Main features of the new IPS Alpha panel:
1) Smallest size and highest definition*1 in the world
Thanks to the newly developed pixel structure with ultra-high
aperture ratio, the effects of the electric field have been
significantly decreased. As a result, the 4K2K (3,840 x
2,160: 8.29 million pixels) ultra-high definition, approximately
four times the full HD (1,920 x 1,080: 2.07 million pixels)
resolution, has been achieved on the world's smallest 20-inch
panel, while the IPS Alpha panel's high contrast ratio and
high-gradation color reproducibility are maintained. The
216 ppi resolution - the highest in the world*1 on a 4K2K
display and hardly distinguishable with the naked eye -
delivers details of an image with extreme precision.
2) Thinnest in the world*1 and energy-efficient
Thanks to the newly developed pixel structure with ultra-high
aperture ratio, the industry's top-level IPS Alpha panel
transmittance becomes approximately twice that of the conventional
structures*8. Since the new pixel structure allows for effective
use of backlight, the thickness has been reduced to 3.5
mm, the thinnest in the world as a 4K2K panel. Furthermore,
compared to full HD LCD panel of the same size, the new
ultra-high definition 4K2K panel produces four times the
volume of information using the equivalent amount of electricity.
3) Wide viewing angle was achieved in all directions
An IPS Alpha panel conventionally has wide viewing angles
of 178 degrees both horizontally and vertically. Thanks
to the new liquid-crystal molecular orientation process
technologies that further improve the liquid-crystal molecular
orientation performance, the diagonal viewing angle has
been significantly improved. The new IPS Alpha panel will
let viewers enjoy high-quality videos with excellent color
reproducibility from wider angles.
