Post by thread:[BUY]:searching for mini lcd high resolution scre

!!!! No such LCD exists, except perhaps in IBM's labs. The highest resolution LCD you can buy right now has a maximum resolution of 200 pixels per inch. An article about it can be found here: www.extremetech.com/article2/0,3973,525370,00.asp Viewsonic sells them, 22.2" displays with a resolution of 3840x2400. You could purchase LCD's meant for projectors, but mostly those top out at 1024x768. Actually, now that think about it, your best bet is probably to get a 3 LCD projector that has as high a resolution you can find (1600x1200, perhaps) since the LCDs themselves will be monochrome. Out of curiosity, what do you need such a high resolution LCD for anyway? -Adam edg wrote: {Quote hidden}>Hi, >i'am looking for a monochrone mini high resolution lcd screen (size say >around 10 x 5 cm) and with a resolution of min 3200x2500 pixels. i have >search on internet, but i haven't found it. > >etienne > >-- >http://www.piclist.com hint: The list server can filter out subtopics >(like ads or off topics) for you.

Sorry to let you down but its not possible today or any time soon. 10 CM is 100,000 microns. This would give you 32 micron pixels. This is easily possible with photo-lithography but because the resistance is high for indium tin oxide, the clear metal, used to make the capacitors in the display. You also need a 6-10 micron pixel gap. Also this doesn't take into account the space for the LCD trace routing and glue seal which would also cut down your size. You can't buy LCD Drivers buy drivers that have that many I/O, max is about 250 per die. Also the pad size is limited -- ~50 microns per pad. So bond space for the drivers would be bigger than the display active area. With Poly-silicon TFT technology this is possible, but not yet available and expensive ~ $60-$100 in very large quantities. With Poly, the drivers are built into the "Glass" (Actually in the poly layer itself). They want to mostly make color anyway. You could easily get 128, 256 x 64 or by 80 in graphic LCD. Cellular phones are about this size. One place to get a high resolution display is from one of the LCD on silicon (LCoS)- Heads up display people, Three Five Systems, H.P. or Colorado Micro displays. Probably you could buy a prototype - but probably not monochrome and not cheap. They are also 1024x768 or similar format and smaller. These are used in rear projection TV's and camcorder viewfinders. Check out http://www.threefive.com where you can read about them. Also check out ww.sid.org for general display links and information. Also you have another problem with the multiplexing a passive STN's are limited in resolution. So you need a TN cell with active matrix drive to get that kind of resolution. In short your resolution is way too high to fit into that space. Even a desk top LCD is only on the order of 1024x768 - so 3x this for monochrome in a 15" display. IBM showed a research model that was higher density, but not a production model. Most people who want TFT's want color, so most high resolution, small displays are color.

Thats a very high resolution in a small size! Do you realize that the pixel pitch is only 100mm / 3200pixels = 0.031mm/pixel? Normal color CRT monitors are in the .22 to .28 "dot" (triad, actually) pitch range. Another way to look at what you are asking for is in terms of DPI: 3200dots / (100mm / 25.4 mm per inch) = 3200 dots / 3.94 inches = 813 DPI This seems rather absurd. What are you trying to do? ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Ye gods. The only place you have any real chance of finding an LCD screen with that kind of pixel density is some sort of medical imaging application, and my guess is that you won't like the pricing. The only people that would even think about making something like that-- and I'm not at all sure that they do-- are probably IBM, Sharp, and Hitachi, probably in that order. What in the world prompted that kind of a part? {Original Message removed}
