Hello, I have a question about a 4-inch display. I can't change the LCS lighting so that it can't be turned off, but only slightly affects it.
That is, if I specify "0" to turn it off, it continues to light up as before using pin 6.
If I use PWM control and specify value 255, the screen remains only slightly darker. Does this mean that there is a problem with the screen itself or the ESP32 board, or should I use a different type of lighting regulation commands?
