White LED Backlight Module Shape

Post by poulp »

Hello,

I'm interested by the LED Backlight module, but i would like to use a triangle shape. Do you know if this product exist in triangle ? Is-it possible to cut the regular shape you sell ?

Thank you very much for your help.

These are designed for standard-sized LCDs, so they are all rectangular. But you should be able to cut them - just be careful not to cut the part that has the LED in it.

Great, I just had this question today! So if I go by the datasheet, is it correct that the LED is only within the trapezoidal area and not within the rectangle of the light area? Meaning that I can cut anywhere in the light area rectangle without being in danger of touching the LED?

Thanks,
Ayo

I haven't cut one open personally to verify that, but I'd go by the data sheet. Let us know if it doesn't work as documented, post a photo of what you find and we'll send a replacement.

Update: It still looks pretty good (and works), the lighting isn't quite as even near the part that is cut due to the fact that you lose the reflective strip on that part. I'm going to try coating the cut edge with a silver paint marker or applying some foil to see if that helps. Overall not a huge decrease in performance.
