A few days ago LG Display announced that they have developed the world’s largest 55-inch OLED (Organic Light Emitting Diodes) TV panel. It uses an Oxide TFT technology for backplane that is much cheaper than the LTPS (Low Temperature Poly Silicon) based panels. Oxide TFT performs equally to LTPS with the only difference of replacing the more expensive Amorphous Silicon used in LTPS technology with Oxide to come up a much cheaper technology that allows LG Display to create larger displays at a reduced cost.
OLED is a medium that controls pixels that has many advantages compared to liquid crystals used in LCD. This new technology utilizes light emitting diode that has the capability to self-generate light. Because of this, there’s no need for a separate light sources found in backlight units used in LCD panels that must always be kept on. As a result OLED will consume less power because diodes can be turned on or off when needed. This will surely make nature lovers happy knowing that OLED TV panels are environment friendly. Finally, by eliminating the need for a separate light source, OLED TV panels can be created thinner than that of a pen (5mm) and lighter than its LCD counterpart.
“Our objective has always been to actively define and lead emerging display technology markets,” said Dr. Sang Beom Han, CEO and Executive Vice President of LG Display. “Although OLED technology is seen as the future of TV display, the technology has been limited to smaller display sizes and by high costs, until now. LG Display’s 55-inch OLED TV panel has overcome these barriers.”
Additionally, OLED panels control small pixels that feature a reaction velocity to electric signals over 1000 times faster than liquid crystal. This results to a remarkable viewing experience with no after image as well as high contrast ratio of over 100,000:1 and wider color gamut than that produced by LCD panels.
The first world’s largest OLED HDTV panel at 55 inches can be seen at CES 2012 on January 9 in Las Vegas. For the meantime we can feast with our eyes with the images below.
