I say avoid analogue clocks. People younger than I am are less and
less likely to be able to read an analogue clock. In point of fact. I
have to decipher them.
This means I can't 'read' them. I can figure them out, the same
way I can figure out a word I've never read before. But it takes a
lot

Just to be pedantic, this will not prevent burn-in. This solution
causes the display to fail sooner-but-evenly. *All* the pixels will
wear out at the same time --
True true. But if the clock is always on, those pixels will fail at
the same rate that they would in either case.
So the display will get dimmer over time, rather than show 88:88 dim
with the rest of the screen bright.
It turns illegibility into readable by dark.
So if you take all the other
Thanks for the few direct and the many consultant/zen-like responses
(don't use a clock, etc). Yes we are providing the option to turn
off the clock display and it will also become dimmer after a period
of inactivity.

To not address the clock/no clock issue (as it could be specific client
request, etc.)
Assumption here: the appliance is in a fixed location like the kitchen.
Do you have control over the brightness of the display? One option would be
to have a light sensor in the device where you detect the
Why don't you actually use the clock information to reduce burn-in?
Surely not many people will be cooking late at night and early in the
morning. So just do a rough estimate and say not many people will be
using the cooker between 10pm and 6am, thats an 8 hour period where

Eeww.
Use case failure: swing shift worker
Use case failure: busy mom, up before dawn
Use case failure: set time after the power comes back on late at
night, zap, display goes dead (this could be worked around, assuming
someone thought about it)
There are also non-use cases surrounding
Looking for suggestions to avoid clock burn-in. This is a small display on a
consumer appliance that displays the time in digit or analog format when not in
use. We don't want the clock to move around (like a screen-saver). What are
alternate ways to deal with this?

Rob,
Pardon me for not addressing your question, but having just posted to
my blog about clocks on appliances (http://designaday.tumblr.com/post/58432215/overclocked
), I have to ask. Is it really beneficial for this particular
appliance to have a clock, and is its use optional?
Best,
Hi,
I'd second what Jack offered - about necessity only I'd take this from
another angle - ease of use. Hear me out on this. We have 5 digital
clocks in our kitchen, not individually by choice. The stove, an under
the counter CD player, an under the counter TV/Weather radio, a
microwave,
Is it possible to do a slight shift throughout the day? For museum
kiosks we did a pixel range in which we shifted the logo up, down.
left right to minimize burn in. Perhaps this could be done at the
turn of each hour to minimize the visibity of the shift.

And please think of all those poor souls who would like to save energy and

all on a powerstrip, so as to be able to turn them all off at night or when
otherwise not in use and be greeted with a forest of blinking lights
Hi Rob,
Rather than reframe the problem, I'm going to try to address the
question you asked but it would help to know a little more about the
type of display you're working with.
If it's a CRT, it seems like the analog clock would result in less
burn-in than the digital clock because the hands
Good comments about not using the clock at all.
If you must, you can try a combination of analog and digital clock, where
large digits move in a narrow circle over the 12 hour period.
