“…The emerging micro light-emitting diodes (MicroLEDs) are anticipated for the nextgeneration displays, especially augmented reality (AR) or virtual reality (VR) as well as for wearable, portable devices [1][2][3][4][5][6][7][8][9][10][11], visible light communication (VLC) [12][13][14][15][16], and optogenetics [17,18]. The self-emissive MicroLEDs can generate bright images efficiently without external light sources and lossy optical components.…”

In this article, an active matrix (AM) micro light-emitting diode (MicroLED) display with a resolution of 1920 × 1080 and a high pixel density of 3200 pixels per inch (ppi) is reported. The single pixel with a diameter of 5 μm on the MicroLED array exhibits excellent characteristics, including a forward voltage of 2.8 V at 4.4 μA, an ideality factor of 1.7 in the forward bias of 2–3 V, an extremely low leakage current of 131 fA at −10 V, an external quantum efficiency of 6.5%, and a wall-plug efficiency of 6.6% at 10.2 A/cm2, a light output power of 28.3 μW and brightness of 1.6 × 105 cd/m2 (nits) at 1 mA. The observed blue shift in the electroluminent peak wavelength is only 6.6 nm from 441.2 nm to 434.6 nm with increasing the current from 5 μA to 1 mA (from 10 to 5 × 103 A/cm2). Through flip-chip bonding technology, the 1920 × 1080 bottom-emitting MicroLED display through the backside of a sapphire substrate can demonstrate high-resolution graphic images.

“…It generates a reasonable decision and goal [2,3] for the animals based on the status of the environment and propagates the outputs down to the following layers for execution. The navigation layer is responsible for path finding of a trajectory that connects the animal's current location to the targeted location, and avoiding collisions with any of the static terrain obstacles [4,5].…”

Firstly, I would like to express my sincere gratitude to my supervisor: Prof. Lin Feng, for his patient guidance throughout my two years of Master's study. I would also like to thank Prof. Seah Hock Soon for his kind assistance on my research as well as preparation of the papers. Lastly and most importantly, I want to thank my beloved father and mother in China for always providing me with enormous financial and mental support even at such a great distance that separates us. vi

It has always been a hot topic to achieve a near‐eye display with a large field‐of view (FOV) and high‐resolution. Multiple display panels can be employed to break the resolution/FOV invariant in tiling methods and overlapping methods. Several prototypes have also been developed to provide a super‐resolution image with a large field‐of‐view and a high‐resolution using multiple panels, which can verify the presented methods.
