So I needed a graphing calculator for school. One teacher I know recommended the new CX model as it has "more functionality" vs the non backlit grayscale LCD. Obviously I was a bit worried about PWM so I preemptively emailed TI. This was the response I got.
What can I say? So laughable. Remember I spoke with the head of "panels and optics" for a certain fruit-company? And people say Apple is strict about nfo and leaks 😃
Well I ordered the calculator anyway and it came this evening. First thing I did was test it for PWM flicker. Verdict: appears to not use PWM.
