We're hoping to build/sell a product that's basically a
color display on a surface. There's still a number of problems to
overcome before it's a reality, firstly the underlying display
technology, and so my question is in regards to what display
technology will best suit our minimum requirements.
From a scarce number of books to the plethora of internet websites
we've gathered names like: OLED, Ferroelectric, Twisted Nematic LCs,
Electronic Ink/Gyricon, Field Emissive Display, etc. There really is
no shortage of display technology types. We'd like to incorporate one
of these display types (or perhaps a hybrid) in order to satisfy our
future product's display capabilities. However, which of these
display technologies "comes closest" to matching our needs is the
unknown.
Our product's minimum requirements are as follows:
% % % % % % % % %
++ Display Type: Ambient light reflective >= 40% reflective,
Multistable - It makes use of ambient light to be viewed and is
multistable so that once power is applied to change the display no
additional power is required to sustain the static, color image, at
least not for a long period of time. No backlighting required.
++ Color: >= 256 Colors per pixel, thus >= 8 shades/intensities per
subpixel. OR, if its affective, something similar to Inkjet Color
Printing using the CYMK model and dithering, thus 4 specific colors
per pixel. Graphical display.
++ Resolution: >= 40 pixels/inch | Display Area Dimensions: <= 2"W x
5"L ==> 80 x 200 display resolution.
++ Speed: For the aforementioned Resolution, animation display rates
would be nice but not essential. >= 1 frame/10sec
++ Thin Profile: <= 3mm thick that includes substrate, and addressing
technology.
++ Surface Type: If possible, the display technology and enclosing
substrates can be permanently placed onto a small, gently curving
surface. Segmentation of the display may be necessary as a uniform
rectangular display is not likely due to some areas being broken by
3mm plateaus/holes spaced by 5mm gaps.
++ Availability: The display technology is available in production
quantities within the next 2 years

At the moment the display technologies we think "come closest" to
matching our aforementioned needs are: Electrochromics, Cholesteric
LCs, Fast-response Multistable Liquid Crystals (FMLC), PDLC,
Electronic Ink/Gyricon, and Guest-Host techniques.
What existing display technologies would you consider as top picks for
further investigation?
Also, we're always open to book recommendations, URLs to explore,
company names, and email addresses. Any additional information
provided would be much appreciated.
