Backlight

Backlight topics are where display theory turns into battery life, heat, and real user comfort. For consumer TFT products, the backlight is not just a brightness number on a datasheet. It affects outdoor readability, dimming smoothness, enclosure temperature, EMI behavior, and how long the product can run between charges. The articles in this tag are useful when you are comparing LED driver choices, PWM settings, luminance targets, or the trade-off between a brighter screen and a thinner device.
