Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation application of U.S. application Ser. No. 16 / 128,255, filed on Sep. 11, 2018, the entire contents of which are herein expressly incorporated by reference.BACKGROUND OF THE INVENTION1. Field of the Invention

[0002] 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

[0003] 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.

[0004] 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 technolog...
