Abstract

Abstract : Guangdong Juhua has fabricated the world's first 31 inch, 4K, H‐QLED TV, by using ink‐jet printing technology. The Red and Green pixel of H‐QLED TV is made from electrical luminescence quantum dot (QD for short) materials, and Blue pixel is made from soluble blue OLED material. It is a self‐emitting and top emission display with excellent performance brought by quantum dot materials, which provide large colour gamut, wider view angle, high luminance and high resolution.
