Hey,

I’m trying to figure out what the highest pixel density in production LCD/OLED modules that is currently (or recently) available. Note that I’m not looking for PC monitors, but rather the actual display module of _any_ physical size, including tiny display modules for consumer electronics and giant LCD TVs (which obviously don’t apply).

The highest I was able to find was whatever LCD is used inside this [22" IBM LCD Monitor](http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-54982) which seems to be around 216PPI. It is no longer in production.

I can’t figure out how to find this information. This information isn’t published so I have to calculate it by hand which means I need viewable area WxH and resolution (or diagonal, aspect ratio and resolution). This is proving to be a giant hassle and after sorting through a few dozen datasheets that all turned out to be around 100 PPI I’m a little discouraged.

Are there any LCD/OLED modules over 600PPI? 400PPI? 300PPI?

Thanks,

Groman

P.S. Yes. I am obsessed with this subject, but it’s very important to me in a religious way

LCD projectors of the type used in conference rooms can have resolution of 1024x768, but the panel itself is quite small (one or two inches?), so I think the pixel density is quite high. (Except I think there are three LCDs in each projector, so each is monochrome.)

I think all of those are DLP. I’ve never seen an LCD projector like you describe.

Edit: I take that back. [Here’s an Epson description.](http://www.3lcd.com/structure.html) and [here it shows a 0.9" LCD panel](http://www.3lcd.com/structure_close_up.html#lcd_panel).

Thanks.

Ok so the current winner is

Epson L3C07U Series HTPS LCD Panel 0.7" diagonal 1920x1080 monochrome

at about 3150PPI

Do we have anything denser?
