Abstract
An LED device in which LED groups are located on a pixel board has calibration data for each LED stored both electrically and mechanically close to the actual LED. Preferably, each LED group has a number of LEDs of different colors on the pixel board, being electrically connected to a color controller. The color controller is connected to a power supply, and the pixel board has a memory circuit having the LED calibration data related to the LEDs stored therein. The color controller controls LEDs for generating light based on the LED calibration data stored in the memory circuit on said pixel board. Preferably, at least one of the LEDs is formed on a chip that contains the memory circuit for storing the calibration data.
