Recommendations for a QVGA LCD Display
Posted by armarm123@hotmail.com on February 10th, 2005


I'm looking for a Transflective, Landscape, QVGA (320X240), TFT with
Touch screen and LED backlight.

There are a number of displays that come close (Sharp LQ036Q1DA01 (no
touchscreen), Torisan/Sanyo TM038QV-67A02A (no LED backlight), Sanyo
TM035QV-67P06A/Sharp LQ035Q7DB02 (portrait mode only)), however, I
cannot find one that matches all my requirements.

Can any one help ?

The display in the Garmin SteetPilot c330 GPS navigator
(http://www.nightowlgps.com/garmin/pr...ilot-c330.html)
looks ideal, however, I cannot find out who makes it (and cannot afford
the $1000 to but one).


Thanks in advance...

Hugh,,

How many years will you want to buy this? Is it a one-off or a 10 year
product? My comments apply to long life-cycle YMMV...

Stay away from Sharp. The question I learned to ask vendors is "have you
ever cancelled a screen even though someone wanted to buy it?" Sharp failed
that test on two different screens that we were using. The second one was
cancelled before we even got the design into production. We spun one board
to use a Tianma/Optrex (one of the few times I've found 2 manufacturers make
drop-in replacemnet LCD) and the other product will probably get a Tianma.

Not a problem: Fujitsu makes various size touch screens. Superglue, double
sticky tape, or whatever will mount it to the LCD panel. Also, many of the
smaller venders offer the TS as an option.

I haven't looked at Sanyo, but if they chase the PC market, they are
probably just as bad as Sharp.

Try Tianma, Optrex, Hantronix, Densitron, AZD, Microtips. They seem to serve
embedded folks way better than Sharp (LCD) and 3M (for touch screens).
