Does a LED backlight need a resistor?
Can I turn on a LED backlight without a resistor?

Re: Does a LED backlight need a resistor?
Yes, there needs to be a resistor in series with the positive side of the power supply. The smaller the resistor, the brighter the backlight. The brighter the backlight, the shorter it's half-life. What in the world is half-life? click here. https://focuslcds.com/journals/the-half ... acklights/
