Apr 29, 2020 · 삼성디스플레이가 편광판 대신 컬러필터를 적용한 유기발광다이오드 (OLED)를 내놓는다. 원래 컬러필터는 LCD 안에서 발색을 담당하는 역할이지만, 삼성디스플레이는 컬러필터의 외광차단 기능에 주목하고 있다. 이를 통해 OLED의 발광효율을 높이고, 언더패널카메라 (UPC, Under Panel Camera) 구현에 필요한 광투과도를 확보한다는 목표다. HIAA 기술이 적용된 스마트폰 (왼쪽)과 UPC 기술이 적용된 스마트폰. 삼성디스플레이가 COE를 구현하려는 이유는 UPC와 …

Dec 16, 2022 · This year, Samsung Display and BOE introduced a new pol-less display technology to customers as a low-cost alternative to color filter on encapsulation (COE). Compared with the original COE structure, the low-cost pol-less technology removes the entire color filter (CF) and black matrix (BM) layer.

COE技术，在OLED屏幕表面形成一层对应于OLED亚像素的RGB透射薄膜、并在亚像素之间的空隙使用黑色材料。 其中，黑色材料能做到对环境光的全波长高效吸收；RGB三原色材料，能保证8成乃至更高OLED材料反射的显示光线透过，并进一步提纯的同时，亦能有效吸收环境光线中非对应原色的其他波长光线。 对比于偏光片而言，COE是更为复杂的结构，其取得的对环境光的吸收效率亦与偏光片相当。 但是，对于OLED发射的显示光线，偏光片的理论透射率只有50%； …

Sep 3, 2024 · The growing demand for foldable OLED smartphones has led to a significant forecasted increase in the adoption of Color Filter on Encapsulation (COE) technology, which is expected to achieve a compound annual growth rate of 33% between 2024 and 2030.

Sep 20, 2024 · This article is a comprehensive review of color filter on encapsulation (COE) technology. It analyzes OLED glare reduction approaches, COE benefits and challenges, manufacturing, costs, and forecasts adoption.

Find out how to wire an LCD to an Arduino, and how to use the LiquidCrystal library through a set of useful examples. This article was revised on 2021/11/18 by Karl Söderby. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.

Mar 29, 2021 · This structure has been called On Cell Polarizers (OCP) and Color On Encapsulation (COE) in the past. The first AMOLEDs without polarizers are now expected in the Galaxy Fold 3 in Q3’21. The circular polarizer in AMOLEDs is used to reduce reflection.

Sep 15, 2023 · 폴더블폰 시장 확대와 함께 편광판을 없애 소비전력을 아끼고 빛 투과율을 높이는 'CoE'(Color Filter on Encapsulation) 기술 적용이 늘고 있다. 2년 전 삼성디스플레이가 폴더블 패널을 공급한 삼성전자 갤럭시Z폴드3가 CoE 기술을 적용한 첫 모델이었다.

Mar 26, 2021 · This article lists four potential structures that COE technology can be applied to and analyzes their advantages and disadvantages.
