I mean, if they are able to emit violet light, it shouldn't be hard for them to go slightly up a notch and emit UV rays. Are those UV rays harmful enough to be considered ionizing radiation?
-
In the past CRT tubes emitted not only UV but also X-rays.
Lead glass and shielding was used to reduce this.
Today we use LCD displays and passive transistor arrays.
The amount of high energy radiation created is similar to that of any related light source.
It may well exist in small amounts.
Even an ordinary incandescent light bulb does produce SOME UV radiation.
But is it enough to be significant? Unlikely.
Any UV is lost energy as far as the backlight is concerned so naturally the light source is made to minimize the amount of this wasted energy.
Modern low powered LED lights are very efficient. Which in turn means that there is not much outside the visible spectrum.
