32‐4: High transparent Active matrix Mini‐LED Full Color Display with IGZO TFT Backplane

Abstract

In this paper, we presented a active matrix Mini LED full color display with high transmittance over 60%. A 8-inch display with RGB Mini-LED with IGZO TFT backplane was demonstrated, which is 46 PPI pixel resolution and 256 grayscales and the pixel pitch is less than 0.55mm. It is the first time to realized the full color display based on RGB Mini-LEDs and chip on glass with top gate structure IGZO TFT backplane. We believe that it is a good breakthrough and demonstration for developing large-size Micro LED backplane and displays.

2.3: High Mobility Top‐Gate Self‐Aligned and BCE a‐IGTO TFTs Application to Micro‐LED and Mini‐LED Display

“…Advantages like high efficiency, high brightness, long lifetime, wide color gamut and narrow emission peak and scalability make mini-LED or micro-LED technology one of the most promising candidates for future flat panel displays [1][2]. On the other hand, an amorphous indium gallium zinc oxide (a-IGZO) thin-film transistors (TFTs) have become a standard backplane technology for the mini-LED and micro-LED equipped with much higher current and brightness without sacrificing lifetime, due to their high mobility, extremely low leakage current, good uniformity and electrical stability [3][4].…”

55.2: A Novel Sn Paste Free Approach for Manufacturing Mini‐LED Display

“…As to Mini-LED displays, the Sn paste printing method are investable for conventional manufacturing method. In 2018, an 8-inch high transparent full-color AM-MLED display based on conventional method was demonstrated [2] . Nevertheless, the printing process would easily lead to short-circuits phenomenon between different signals inside the pixel.…”

16‐2: A 4‐inch Full Color Active‐matrix Mini‐LED Display based on 0408 Chip and 500um Pixel

“…With reduced both sizes, the display performance would be improved while simultaneously the manufacturing and design complexity would also become higher. In 2018, we have already demonstrated an 8-inch high transparent full-color AM-MLED display based on 550um pixel and 0509 chip [2] . In this paper, we presented a 4-inch full-color AM-MLED display with 500um pixel and 0408 chip which are currently smallest for Mini-LED displays to be best of our knowledge.…”
