Very simple - just 4 lines of white text on a black background. Today I noticed that after just a few days I was starting to see dimming of some pixels that were constantly on. Looking over the product page I noticed a caution that OLEDs will start to dim if left on. Oops...\u003c/p\u003e\n\u003cp\u003eTFT's use backlight LEDs, and typically there is a backlight pin which could be used to dim or even turn off. I learned, however, that OLEDs are individual organic LEDs, so there is no backlight pin.\u0026nbsp;\u003c/p\u003e\n      ","metadata":{}}]
