Re: [IxDA Discuss] Clock Burn-In
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 more time. If you simply must have a clock, and it can't move. I'd do any or all of these things: (some people have already said) -Alter the color over time. -Use a font or fonts that activate the widest set of pixels. -Swap the font around over time. -Slowly move the clock. But really... if you want to eliminate burn in entirely. Just revert the display once a minute. Make the off pixels on, and the on pixels off. This will prevent burn in, as all the pixels will get exactly the same amount of wear, and it will also alert the user that the minute flopped, which is pretty handy if you are timing something by hand. This also works with very small displays. If the display is dot-matrix, this works. Just be careful about the font, text needs to be thicker to be easily read in revert. Anyway. That's my 2 cents.

This solution causes the display to fail sooner-but-evenly. *All* the pixels will wear out at the same time -- and sooner -- than they would if the display had been powered down. -- J.

Re: [IxDA Discuss] Clock Burn-In
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 precautions, you'll still see less burn-in. But clearly, it isn't a best-case option if you are talking about a full size display. The other options are best for that. When you talk about a small display, like you might find on a car stereo, this will prevent burn-in.. Burn-in being defined as an after-image left behind due to uneven degradation of the screen. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Clock Burn-In
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. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Clock Burn-In
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 ambient room lighting. In brightly lit rooms, you could up the brightness of the display and in dimly lit rooms the probability of use might be lower (again, not knowing your product or its application) so you could reduce the brightness level. At least 1/2 the time the room would be dimly lit (at night) It is, however, an additional part cost as well as EE/embedded SW dev cost.

Re: [IxDA Discuss] Clock Burn-In
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 the digital display could be turned off. Obviously if people started to use it during this period, the clock would reappear! I am sure this could be used for different appliances as well. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Clock Burn-In
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 these clocks. I often use them to guide me in the house without turning on lights (to not wake up other people, or just because I can), for example. -- Jim Via my iPhone On Nov 11, 2008, at 10:12 AM, Thomas Davies [EMAIL PROTECTED] wrote: Why don't you actually use the clock information to reduce burn-in?

[IxDA Discuss] Clock Burn-In
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?

Re: [IxDA Discuss] Clock Burn-In
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?

Re: [IxDA Discuss] Clock Burn-In
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, and a coffee maker. Now every time the power flickers for more than 1/2 a second, I have to go reset each one back to the correct time. And guess what? The UIs for setting the time on each device are all different. Unfortunately the designer/mfr did not include a battery/capacitor backup for carrying the clock chip through such brown outs. Trust me this is a pain. I think right now if I had to purchase another appliance, I'd go out of my way to not get one with a clock. ;-} No wonder so many households have the flashing 12:00's on their (old) VCRs. best, 'mark Jack Moffett wrote: 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.

Re: [IxDA Discuss] Clock Burn-In
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. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Clock Burn-In
And please think of all those poor souls who would like to save energy and turn their appliances off-off when not in use. It's a real pain to put them 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 when flipping the switch to on again.

Re: [IxDA Discuss] Clock Burn-In
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 would be constantly in motion. If you're going with a digital form, and you can't move the clock, then you're only left with the options of turning the clock off periodically or modulating its color. The best thing (strictly from a screen-burn perspective) might be to select a font with maximum variability in form between successive numerals. If it's an LCD then as long as you're using the display for something besides the clock when it's in use, this should be much less of a problem. You can prevent image persistence by turning off the display for a few minutes each day. // jeff . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Clock Burn-In
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. -- Oleh Kovalchuke Interaction Design is design of time http://www.tangospring.com/IxDtopicWhatIsInteractionDesign.htm On Mon, Nov 10, 2008 at 8:34 AM, Rob Tannen [EMAIL PROTECTED]wrote: Looking for suggestions to avoid clock burn-in.
