Sony OLED Displays Coming Soon
A new article has been published which confirms and earlier PalmInfocenter story about Sony planning to use Organic LED display technology in a future handheld. The report claims Sony has developed a new OLED display to be used in a yet unnamed PDA line sometime in the Spring.
The new report in Digitimes states, Sony has announced that in the spring of 2004 it will commercialize an active matrix OLED (AMOLED) PDA panel using LTPS (low-temperature poly-silicon) from Sony-Toyoda’s line. The PDA panel will be three to four inches in size diagonally, a significant increase for OLED dimensions. This display is likely to be only the second AMOLED product on the market. [...] Because the PDA market is relatively small, Sony can supply enough panels for a whole product line, even at the early stages when its AMOLED yield is somewhat low.
This article confirms and adds credit to an earlier report that claimed that Sony would have a PDA out in the Spring of 2004 with an OLED display. Sony is expected to officially announce the TH55 and TJ37, and TJ27 at the PalmSource Developers Conference Tuesday in San Jose. Those models have already been released in Japan and Hong Kong. There is no information available of yet to indicate whether they will have OLED screens.
About OLED Screens
Organic Light Emitting Diode (OLED) is a generic term for a whole group of possible screen types. OLEDs are made up of thin films of organic materials that give off light of various colors when voltage is applied to them. Like LCDs, OLEDs have both active matrix and passive matrix forms.
The main advantages of OLED screens over current ones is the screen itself glows so there is no need for a back- or side-light. This means they require less power and take up less space, two important factors in a handheld. They also cost less to make.
OLEDs have a faster response time so they are also better able to show video. They can be seen from wider viewing angles. They are less susceptible to heat and cold. OLEDs have fewer manufacturing steps and use both fewer and cheaper materials than LCDs do.
Numerous companies are working on developing OLED screens, like Sony, Pioneer; and TDK. Research scientists at Kodak invented the OLED in the early 80s and the company continues working with them today.
