An adaptive equalization method and system for automatically adjusting an equalizer to compensate a signal's frequency dependent loss is disclosed. The method comprises setting the equalizer's initial coefficient value, receiving an equalized signal, identifying a positive to zero transition of the equalized signal, generating a common mode voltage from the equalized signal, and determining the equalized signal's tail settling voltage. The method further comprises comparing the equalized signal's tail settling voltage to the common mode voltage, determining if the signal is over equalized or under equalized based on the comparison, and adjusting the equalizer's coefficient value based on whether the signal is under equalized or over equalized.

The subject of this invention is a full-color display device based on III-Nitride semiconductors. The display device includes an array of micro-LEDs, monolithically integrated on a single chip of the epitaxially grown LED heterostructure, and flip-chip bonded to a silicon backplane of active matrix driving circuits, and color conversion layers. The LED substrate of the micro-LED array is removed, and the n-regions of the p-n or p-i-n heterojunctions of the micro-LEDs are connected via a thin n-type III-nitride epitaxial layer less than 20 μm thick. The surface of the thin n-type III-nitride epitaxial layer is covered with a layer of transparent/semi-transparent conductive material, forming the common n-type electrode of the micro-LED devices, rendering the vertical current flow in the micro-LED emitters. Each addressing and driving pixel of the active matrix driving circuits contains at least a switching transistor, a switching-driving transistor, and a latch register.
