“…Recently, AUO, iBoson, and JDI have demonstrated fast response LCs for high-resolution VR applications. 81,82 The slowest gray-to-gray response time is below 3 ms, and MPRT is 0.9 ms at 90-Hz frame rate, as reported by AUO and iBoson. In parallel, JDI developed a one-side branch structure to realize a fast response time of 2.2 ms for VR displays.…”

Recently, "liquid crystal display (LCD), organic light-emitting diode (OLED), or micro-light-emitting diode (LED): who wins?" is a heated debatable question. In this review article, we provide a comprehensive overview of these three promising display technologies through nine display performance indicators, including ambient contrast ratio, motion picture response time, viewing angle and angular color shift, color gamut, resolution density, power consumption, cost, lifetime, and thin profile and panel flexibility. The advantages and disadvantages of each technology are analyzed, and their future perspectives are discussed.

“…[ 8 ] To improve their performance, materials with high color saturation and better response time and upgraded backlight unit with better conversion efficiency were used. [ 9,10 ] These modifications improved optical efficiency and color gamut of LCD, however, two‐thirds of light generated is still being wasted. In 1990s, organic light‐emitting diodes (OLEDs) were introduced to display technology.…”

The demand for high-performance displays is continuously increasing because of their wide range of applications in smart devices (smartphones/watches), augmented reality, virtual reality, and naked eye 3D projection. High-resolution, transparent, and flexible displays are the main types of display to be used in future. In the above scenario, the micro-LEDs (light-emitting diodes) display which has outstanding features, such as low power consumption, wider color gamut, longer lifetime, and short response-time, can replace traditional liquid crystal displays and organic LEDs-based display technologies. However, to attain a remarkable position in future display technology, the micro-LEDs need to overcome problems associated with mass transfer and its high cost of manufacturing. Besides micro-LEDs, the other option for future displays includes the usage of color conversion medium (phosphor/ quantum dots) to convert some of the blue light into other colors. In this review, the various mass transfer display technologies and color conversion strategies which are being used for the realization of a full-color display are discussed.

“…Microdisplays are highly attractive to researchers and engineers nowadays because they are widely used in near‐eye display technologies and wearable electronics 1 . Traditional microdisplays are based on well‐established liquid crystal display (LCD) 2 or organic light emitting diode (OLED) 3 display technologies. Compared to traditional displays, light emitting diode (LED) microdisplays offer higher brightness, better outdoor performance, superior stability, and longer lifetime 4 .…”

A passive‐matrix monolithic full‐color InGaN light emitting diode (LED) microdisplay with 40 × 40 full‐color pixels is demonstrated. Each full‐color pixel consists of red, green, and blue (RGB) subpixels that have a pitch size of 40 μm × 120 μm. The full‐color microdisplay is monolithically fabricated on blue/green dual‐wavelength LED epilayers, using red quantum dot photoresist as a color converter. Pure RGB emission and a wide color gamut are achieved, as shown by electroluminescence spectra. Full‐color patterns with controllable grayscale and color mixing can be clearly rendered driven by a full‐color microdisplay controller, indicating tremendous potential of this novel approach for full‐color LED microdisplays in the future.

51‐4: Invited Paper: Ultra‐Fast Moving‐picture Response‐time LCD for Virtual Reality Application

Abstract: A 2-inch LCD with a moving picture response time (MPRT) of 1.1 ms and 0.9 ms at 75Hz and 90Hz frame rates was demonstrated by optimizing the timing of the global backlight technology. Such a fast MPRT for an LCD presents a CRT-like display with crystalclear motion-image quality.
