Description

BACKGROUND OF THE INVENTION1. Field of the Invention

[0001] The present invention generally relates to a light-emitting diode (LED) display, and more particularly to a top emission microLED display and a bottom emission microLED display.2. Description of Related Art

[0002] A micro light-emitting diode (microLED, mLED or μLED) display panel is one type of flat display panel, which is composed of microscopic microLEDs each having a size of 1-10 micrometers. Compared to conventional liquid crystal display panels, the microLED display panels offer better contrast, response time and energy efficiency. Although both organic light-emitting diodes (OLEDs) and microLEDs possess good energy efficiency, the microLEDs, based on group III / V (e.g., GaN) LED technology, offer higher brightness, higher luminous efficacy and longer lifespan than the OLEDs.

[0003] Active matrix using thin-film transistors (TFT) may be used in companion with microLEDs to drive a display panel. However, microLED is made by f...
