Title: Operating Temperature range NHD-10.1-1024600AF-LSXV#-CTP
Post by: darkanoid on August 23, 2017, 02:57:10 PM
Hi, I plan to use the NHD-10.1-1024600AF-LSXV#-CTP for use in agriculture machinery. I'm not sure if this range is well suited for the application in mind, because some machines in some zones of our country are near / below 0 C or near 50 C. And the LCD operating temperature is 0 ~ 50 Degrees Celsius.

So my questions are:
- what happen if the display is near or little below 0 degrees Celsius?
- what happen if the display is near 50 degrees Celsius ?
- Is there any option for this type of LCD with an extended range of temperature, like -20~70 degrees Celsius?

Thanks in advance! (sorry about my english)

Hello,

When operating an LCD close to the lower end of its operating temperature, the display itself will start lagging.
The Rise and Fall times for pixels will start becoming larger, and you will notice that switching screens will take a little bit more time.
At the lower end of the operating range you also run the risk of damaging the LCD due to the liquid crystals freezing.
If used in the cold i would recommend placing a heating element behind or inside the same enclosure as the display to keep its temperature maintained.

On the opposite end, when you run the display above the recommended high operating temperature you run the risk of permanently causing dark spots to appear on the screen.
At or around 50C this shouldn't be a problem. However if you do go above this you can start seeing dark spots appear and if it continues to operate, the spots will become permanent.

The 10.1" TFTs are a new product for us and we do not have any extended range panels available as of yet.
