The common electronic symbol es for backlight boards are compared in Chinese and English as follows:
a. VCC: Supply voltage positive pole, circuit supply voltage (usually 12V or 24V)
b. ON/OFF，ON，EN，ON_ BL, etc.: switch pin, switch signal pin (voltage range usually between 2.5V-5V)
c. PWM, PDIM, VDAJ, BL-PWM, etc.: Brightness adjustment foot or dimming foot. There are two modes for dimming: digital mode PWM and analog dimming DC
PWM is called pulse width modulation, which produces a rectangular square wave signal with a frequency of 200HZ-2KHZ and a voltage amplitude of 3.3V. PDIM is the abbreviation in English, Dim means darkness, and the vocabulary roughly means “brightness“. Simulated dimming is carried out through a DC voltage, usually directly providing a DC voltage of 0V-5V to the tuning pin to control brightness
GND: ground (negative pole of power supply)
LED+: Positive pole of light emitting diode (light strip)
LED -: Negative electrode of light emitting diode (light strip)
The above symbols contain most commonly used es on LCD motherboards and backlight boards. As length as they are connected according to their respective es, there will be no errors.
