> PWM is one of two ways to dim a display; the other is by changing the voltage of every sub-pixel—the analog method. LG uses this approach to adjust brightness for its OLED TVs. These sentences are confusing to me. Am I correct to understand this as saying that LG uses “the analog method” to dim the TV displays (and not PWM)?
