Two questions in the same topic:
- What is the lifetime of the VK202-25 display?
- Can I send the "Display On" command (254 66) very "often" (~100 times with 100ms between each) with no damage on the display?

The life of the display is 20000 hours per half life of a display. You can send that command 100times without damaging the display.

Is the lifetime the same for the vk204-24?

Yes, the lifetime is the same, however the thing you have to worry about with the VFD is burn in...

What is 'burn in' ?

An example of burn in is when you leave your monitor on for awhile without a screensaver, and the image is burnt onto the screen. The VFD works the same way. It is healthy to clear your screen once in awhile if you have a VFD.

So if i leave lcdc running is there any risk of burn in as long as its changeing the screen?
By clear the screen do u mean powering down the unit? Is there a way to power it down completely without unpluging it?

Your screen will be fine if you have the screen constantly moving with LCDC. What I meant by clearing the screen is clear any text or characters off the screen, not cycling the power.

ah thx. Just out of curiosity is there a way to turn it off without unplugging it from the power source?

There is no way to turn off the power, unless you wire up a switch to the display.
