Using pulse-width modulation to dim an LED display causes which effect?

💡 Explanation

PWM dimming reduces the average luminous flux because it rapidly switches the LED on and off, therefore decreasing the time the LED is emitting light, rather than reducing the current continuously, which can affect color temperature.
