MicroLED Display – the next generation display technology
Yun-Li (Charles) Li;Tzu-Yang Lin;Ying-Tsang (Falcon) Liu;Yu-Hung Lai

MicroLED display is considered to be the next generation display technology due to its high brightness, wide color gamut, high aperture ratio, and good reliability. In additional to conventional display applications, MicroLED display can also be used for innovative display applications such as transparent and flexible display. Based on our proprietary PixeLED® display technology and SMAR·TechTM repair solution, we have demonstrated various new applications, such as borderless transparent display, ultra-high brightness wearable device, and ultra-thin flexible display.

Laser Direct Writing for Passive-Matrix μ-LED Displays
Po-Hao Chen;Hsuan-Jen Chen;Chun-Xin Ye;Bo-Sheng Lee;Po-Wei Chen;Po-Wen Hsiao;Dong-Sing Wuu

The passive-matrix μ-LED display with a pixel size of 20×20 μm2 was achieved by using a maskless laser direct writing technique. This system can not only reduce the glass-mask usage but shorten the development time. The illuminance of blue passive-matrix μ-LED display was achieved 516 cd/m2 at 3 V.

High stability Quantum Dots Mini-light-emitted-diode with Atomic Layer Deposition Printed on Black Matrix Layer
Yu-Hau Liou;Hao-Chung Kuo;Guan-Hao Chang;Yu-Ming Huang;Min-Hsiung Shih

In this study, we demonstrate a 3-in-1 mini-LED with 160 x 65µm sub-pixel chip size. The deposition of QD layer by using inkjet printing technique achieved a full-color display. Moreover, the use of the atomic layer deposition avoids the oxidation and steam, maintain the color purity of red and green.

Sandwich Evaporation Technique For Uniform Green Perovskite Light Emitting Diode
Li Jen Huang

In this work, we fabricate MAPbBr3 perovskite with our innovative sandwich evaporation technique (SET) to form green light emitting diodes with better perovskite crystalline property. Our home-made chamber can be vacuumed with common rotary pump. This technique features with low vacuum and low cost approaches.

High efficiency organic non-rare-earth-element micron fluorescent array for display technology
Ching-Fuh Lin;Jung-Kuan Huang;Teng-Yi Huang

Micro-LED of small pixel sizes is very challenging. Here we explore a simple and low-cost approach using exposure, development and etching to produce high efficiency non-rare-earth-element fluorescent arrays without the necessity of mass transfer. We have achieved pixel sizes of 60*20 μm and 6*2 μm fluorescent arrays.
