Published: July 2014

AbstractTo achieve an enhanced image quality in a 55‐inch, 100‐Mpixel multi‐projection 3D display for the medical and educational applications, the projector configuration design was improved, and the brightness uniformity compensation and real‐time calibration were performed. Maintaining the density of light‐field rays is important for an immersive natural 3D experiences, this 100‐Mpixel multi‐projection display was designed to have the same light‐field density as a 300‐Mpixel multi‐projection display, so we could acquire very smooth motion parallax without discontinuity in the viewing angle of 24°.
37.1: OLED Displays under Ambient Illumination, an Implementation of IEC 62341‐6‐2
Authors: Becker Michael E. , Neumeier Jürgen 
Published: July 2014

AbstractThis contribution introduces a first implementation of the measurement setup according to IEC 62341‐6‐2 for evaluation of the effect of ambient illumination on OLED display contrast and chromaticity. A sampling sphere is providing hemispherical diffuse illumination, with and without specular components, in the d/8‐geometry, and a point‐light source is providing directional illumination. From the spectral reflectance factors thus obtained contrast and chromaticity for arbitrary illuminants (i.e. spectra) and illuminance levels can easily be calculated.

37.3: Viewing Direction Measurements with Hemispherical Diffuse Illumination on E‐Paper Displays
Authors: Hertel Dirk , Kelley Edward F. 
Published: July 2014

AbstractViewing direction measurements on reflective e‐paper displays under hemispherical diffuse illumination are an essential part of characterizing reflectance under common usage conditions such as outdoor shade, or indirect indoor lighting. This paper proposes a hemispherical diffuse illumination geometry based on splitting a sampling sphere into two hemispheres to allow the light measuring device to be pointed at the display at different angles. First results on e‐paper agree well with conventional sampling sphere data, show the effects of top layer and surface reflection, and were used to predict the viewing direction distribution of ambient contrast ratio.

38.1: A Low‐Power Fast Readout Circuit using a Dual‐Mode Sensing Algorithm for Medium‐Size Capacitive Touch Screen Panels
Authors: Kim Hyeon‐June , Jo Dong‐Shin , Yang Jun‐Hyeok , Ryu Seung‐Tak 
Published: July 2014

AbstractA new readout circuit architecture for capacitive touch screen panels (TSPs) is introduced to enhance the reporting rate and to improve the signal to noise ratio (SNR) with low power consumption. The proposed Dual‐Mode Sensing (DMS) method finds the actual touch spots without feedback from the TSP to the MCU. In addition, the effect of noise coupled to the touch signal is reduced owing to the averaging effect of the proposed continuous‐time integration (CTI) technique. The circuit was designed for a 0.35 μm CMOS technology. The proposed sensing scheme shows a 257 Hz reporting rate under a simultaneous 10 touch condition on a 10.1 inch TSP, providing a 33 dB SNR with power consumption of 679 μW from a 3.3V supply.

Published: July 2014

AbstractWe examined the visibility of motion artifacts—judder, motion blur, and edge banding—on a Samsung 240Hz stereoscopic 3D (S3D) OLED display. We determined the relative contributions of the frame rate of the content, update rate of the panel, duty cycle, and flash number. We compared the visibility of artifacts on the Samsung display with those on a 60Hz S3D LCD. Short duty cycles and low flash numbers reduce the visibility of motion artifacts.

56.3: High‐Power Laser‐Excited‐Phosphor Suspension in Liquid for Digital Projection
Authors: Li Kenneth 
Published: July 2014

AbstractLaser excited phosphor has been used to excite phosphor material, producing high intensity light output with smaller etendue than that of LEDs with the same long lifetime. But due to the high intensity of the laser light, phosphor with organic binder burns at low power, which requires the phosphor to be deposited on a rotating wheel in practical applications. Phosphor with inorganic binders, commonly known as ceramic phosphor, on the other hand, does not burn, but efficiency goes down as temperature goes up under high power excitation. This paper describes cooling schemes in sealed chambers such that the phosphor materials using organic or inorganic binders can be liquid cooled for high efficiency operations. Confined air bubbles are introduced into the sealed chamber accommodating the differential thermal expansion of the liquid and the chamber. For even higher power operation suitable for digital cinema, a suspension of phosphor in liquid is described suitable for screen brightness of over 30,000 lumens. The aging issues of phosphor can also be solved by using replaceable phosphor cartridges.

Authors: Robinson Michael G. , Woodgate Graham J. , Harrold Jonathan 
Published: July 2014

AbstractA novel directional backlight system for transmissive LCD illumination is described for the first time. By controlling the angular light distribution from the display, very low power consumption can be achieved for a required display luminance, or the backlight can operate with a conventional luminance distribution. Additionally very high display luminance can be achieved at the same power consumption levels as conventional backlight designs. Such a display can achieve good readability in high illuminance conditions, for example in direct sunlight. The backlight optical stack comprises a stepped waveguide Directional Light Guide Plate (D‐LGP), a micro‐structured reflective film and a polarisation recirculation structure that cooperates with an LED array to direct viewing windows to an observer with high coupling efficiency. The system implementation is described and measured performance from demonstrator displays is presented.
