摘要

Abstract

Recently

'Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?' has become a topic of heated debate. In this review

we perform a systematic and comparative study of these two flat panel display technologies. First

we review recent advances in LCDs and OLEDs

including material development

device configuration and system integration. Next we analyze and compare their performances by six key display metrics: response time

contrast ratio

color gamut

lifetime

power efficiency

and panel flexibility. In this section

we focus on two key parameters: motion picture response time (MPRT) and ambient contrast ratio (ACR)

which dramatically affect image quality in practical application scenarios. MPRT determines the image blur of a moving picture

and ACR governs the perceived image contrast under ambient lighting conditions. It is intriguing that LCD can achieve comparable or even slightly better MPRT and ACR than OLED

although its response time and contrast ratio are generally perceived to be much inferior to those of OLED. Finally

three future trends are highlighted

including high dynamic range

virtual reality/augmented reality and smart displays with versatile functions.
