An LED assembly containing separately-controllable regions of LEDs with temperature sensing devices placed to measure the temperature within each region of LEDs. When the temperature difference between two regions becomes higher than an acceptable maximum, the system may adjust the power to one or more LED regions to maintain luminance uniformity. The regions can be arranged vertically or horizontally or both. A software processor may be used to interpret the data from the temperature sensing devices and control the power sent to the various LED regions. Embodiments can be used at least in LED backlights for LCD displays or for LED displays.
