Factors to Consider in Improving the Flat Panel TV Display User's
Universidad CEU San Pablo CEINDO – CEU Escuela Internacional de Doctorado PROGRAMA en COMUNICACIÓN SOCIAL Factors to consider in improving the flat panel TV display user’s experience on image quality terms TESIS DOCTORAL Presentada por: Dª Berta García Castiella Dirigida por: Dr. Luis Núñez Ladeveze and Dr. Damián Ruiz Coll MADRID 2020 ACKNOWLEDGEMENTS A Damián, por creer en mi proyecto y en su proyección. A Luis, por permitirme comenzar y ayudarme pese a las dificultades. A Lucas, por cada detalle, por cada apoyo, esta tesis es de ambos. A Natalia, por ayudarme sin cuestionarme. A Gonzalo, por poner orden en el caos. A mi madre, por darme todos los ánimos. A Teresa, por darme su tiempo, a pesar de no tener. A Roger, por sus palabras, que han sido muchas. A Belén y a Fredi, por cuidar a mi hijo con todo su cariño mientras yo investigaba. A mis amigos y familiares por estar ahí, a veces es lo que más se necesita. Y, por último, quería pedir disculpas. A mi hijo Max. Porque cada página de esta tesis son horas que no he estado a tu lado cuando tú me necesitabas, perdón de corazón. ABSTRACT In the constantly changing world of image technology, many new tools have emerged since flat panels appeared in the market in 1997. All those tools went straight to the TV sets without any verification from the filmmaking or advertising industry of their contribution to the improvement of the image quality. Adding to this situation the fact that each tool received a different name according to the manufacturer, this new outlook has become complex and worrisome to those industries that see their final products modified and have no option of action. -
Advanced Liquid Crystal Displays with Supreme Image Qualities
ADVANCED LIQUID CRYSTAL DISPLAYS WITH SUPREME IMAGE QUALITIES by HAIWEI CHEN B.S. Beihang University, 2013 A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the College of Optics and Photonics at the University of Central Florida Orlando, Florida Fall Term 2017 Major Professor: Shin-Tson Wu ©2017 Haiwei Chen ii ABSTRACT Several metrics are commonly used to evaluate the performance of display devices. In this dissertation, we analyze three key parameters: fast response time, wide color gamut, and high contrast ratio, which affect the final perceived image quality. Firstly, we investigate how response time affects the motion blur, and then discover the 2-ms rule. With advanced low-viscosity materials, new operation modes, and backlight modulation technique, liquid crystal displays (LCDs) with an unnoticeable image blur can be realized. Its performance is comparable to an impulse-type display, like cathode ray tube (CRT). Next, we propose two novel backlight configurations to improve an LCD’s color gamut. One is to use a functional reflective polarizer (FRP), acting as a notch filter to block the unwanted light, and the other is to combine FRP with a patterned half-wave plate to suppress the crosstalk between blue and green/red lights. In experiment, we achieved 97.3% Rec. 2020 in CIE 1976 color space, which is approaching the color gamut of a laser projector. Finally, to enhance an LCD’s contrast ratio, we proposed a novel device configuration by adding an in-cell polarizer between LC layer and color filter array. The CR for a vertically-aligned LCD is improved from 5000:1 to 20,000:1, and the CR for a fringe field switching LCD is improved from 2000:1 to over 3000:1. -

Banks, UC Berkeley, Chair Professor Christoph Schreiner, UCSF Associate Professor David Whitney, UC Berkeley Spring 2015 Perceptual artifacts associated with novel display technologies Copyright 2015 by Paul Vincent Johnson 1 Abstract Perceptual artifacts associated with novel display technologies by Paul Vincent Johnson Jt. Doctor of Philosophy in Bioengineering University of California, Berkeley and University of California, San Francisco Professor Martin S. Banks, UC Berkeley, Chair Stereoscopic 3D displays are able to provide an added sense of depth compared to tra- ditional displays by sending slightly different images to each eye. Although stereoscopic displays can provide a more immersive viewing experience, existing methods have draw- backs that can detract from image quality and cause perceptual artifacts. In this thesis I investigate perceptual artifacts associated with displays, and propose novel techniques that can improve viewing experience compared to existing methods. Chapter 1 presents a broad introduction to the various types of artifacts that can occur in displays, including motion artifacts, depth distortion, flicker, and color breakup. In Chapter 2, I describe a novel dis- play technique, \spatiotemporal interlacing," that combines spatial and temporal interlacing. I demonstrate using psychophysics that this method provides a better viewing experience than existing methods, and I present a computational model that confirms the psychophysi- cal data. -

Authors in [9] have conducted subjective dependent. On the other hand, HFR brings several challenges evaluations and shown that the combination of HFR (100 to the transmission chain including codec complexity increase fps) and high resolution (4K) significantly increases the QoE and bit-rate overhead, which may delay or even prevent its deployment in the broadcast echo-system.

The subjective propose a Variable Frame Rate (VFR) solution to determine the evaluations conducted in [10] have also demonstrated the minimum (critical) frame-rate that preserves the perceived video impact of HFR (up to 120 fps) to increase the perceived video quality of HFR video. -
