Among the dozens of new OLED displays presented during the FPD International 2008 in Japan is Sharp's new LCD panel with built-in memory. The memory enables the LCD panel to retain its display even when the power source is cut off; sort of like an e-paper. One of the differences is that, while the e-paper is generally considered a low-power technology, this one requires "relatively large" energy to save content in its memory. Unfortunately, the underlying principles of this LCD were not revealed during the event. What we know though, is that Sharp showcased both monochrome and 8-color LCD display panels in various sizes (1.7, 2.4, 6.1 and 14.1).

A physical limitation comes in the form of temperature - the LCD panels can only work within the range of -25 to +55 degrees Celsius. Anything above 55 degrees would distort the display while anything below -25 would make it difficult to form the image on screen. Another limitation is the manufacturing costs which, for now, remain a "bit expensive" due to the usage of some materials not found in conventional LCDs. If and when ready for mass production though, Sharp claims the company's old-generation manufacturing lines can be used, so the manufacturing costs will be about equivalent to current LCD panels.
