Toshiba Shows Off High-Def Displays for Phones
Toshiba Mobile Display today announced new displays intended for use in devices such as mobile phones. The displays in question use low temperature poly-silicon (LTPS) technology, also known as p-Si LCD panels. These types of displays can be thinner, lighter, and require less power than some competing screen technologies. One example of a new p-Si LCD revealed by Toshiba measures 4 inches across the diagonal and crams in 720 x 1280 pixels, which makes for 367 pixels per inch. Another display offers 480 x 864 (WVGA) pixels in a screen measuring 3.3 inches at 300 pixels per inch. The displays also reach contrast ratios of 1,500:1, offer wide viewing angles, and high color capabilities. Toshiba didn't say when these displays might appear in end-user devices.
Micro-LED Backlights Could Bring OLED Performance to LCD Screens
AT CES this week, Rohinni demonstrated its micro-LED technology, and provided a glimpse at new backlight technology it's working on for the LCD display panels used in phones. While most LED chips are around 1mm, Rohinni's micro-LEDs are many times smaller and can be placed precisely on thin, flexible plastic sheets.
LG Display Shows Off 5.5-Inch Quad HD Screen
LG Display today announced that its 5.5-inch quad HD display is ready for the company's "forthcoming flagship smartphone," which it says will be released during the first half of the year. LG has scheduled a global press event on May 27, which is when it is expected to reveal the G3 smartphone.
E Ink Reveals Full-Color ePaper Display
E Ink today announced Advanced Color ePaper (ACeP), which is a full-color reflective display. E Ink says this is the first time an electrophoretic display can produce color in every pixel without the use of a color filter array.
New Tech Promises Dense, Efficient, Flexible Displays
A team at Oxford University has discovered a new type of display technology that consists of a simple thin film of phase-change material (PCM) between two thin films of transparent electrodes. The three layers can be applied to very thin, flexible Mylar sheets, creating a flexible display.
