      The FETs using CAAC-ITZO as an active layer have improved performances, which are better characteristics and reliability than FETs using nano-crystal ITZO. Furthermore, constant photocurrent method was carried out to estimate density of deep-level defect states. The results show that CAAC-ITZO has lower density of deep-level defect states than nano-crystal ITZO. We attribute the improvement in reliability of ITZO-FETs to decrease in deep-level defect states of an ITZO active layer, as is the case with IGZO.

      Digital driving offers many advantages for active-matrix organic light-emitting diode displays, for example, the avoidance of Mura artifact and with this increasing yield and lowered costs. But it is more prone to image sticking caused by organic light-emitting diode aging. In this article, we present a method to characterize and compensate organic light-emitting diode aging in a digital active-matrix organic light-emitting diode system, which may lead to a display lifetime similar or even above analog-driven displays.

      In the case of LC cell with w = 3 and l = 4.5, when the cell gap (d) reduced from 4 to 2 µm, overall light efficiency of LC dropped by 16% because of rapid decrement in light transmittance through the center of pixel and counter electrodes as well as at both edges of pixel electrodes. However, when w = 1 µm and l = 1.5 µm, maximum transmittance was noticed, irrespective of the cell gap.

      Article first published online: 13 NOV 2015 | DOI: 10.1002/jsid.398

      Thumbnail image of graphical abstract

      We established a fabrication process of flexible displays, adopting a transfer technology using an inorganic tungsten separation layer. Separation does not require laser irradiation or heat treatment and can be performed easily using physical force and water. We succeeded in building the apparatus for fabricating flexible displays and prototyped the 13.3-inch 8k4k flexible organic light-emitting diode display using the apparatus.

    2. Fabrication of 8K4K organic EL panel using high-mobility IGZO material

      A 13.3-inch 8k4k organic light-emitting diode display based on a newly developed high-mobility indium-gallium-zinc-oxide material was fabricated. The high-mobility material was obtained by optimizing the composition. It was found that the use of the higher-mobility material decreases the scan driver size and power consumption. Furthermore, such oxide semiconductor layers with a buried channel structure can increase process stability and reliability.

    3. Sparkle measurement revisited: A closer look at the details

      Article first published online: 13 NOV 2015 | DOI: 10.1002/jsid.391

      Thumbnail image of graphical abstract

      We introduce and discuss details of a method for evaluation of visual sparkle, a random pattern of light intensity variations across the display area that is changing with viewing direction. Implications from observation conditions on the resulting imaging (sampling) and filtering are described, and the separation of statistical and periodic intensity modulations by convolution with a kernel with rational dimensions is illustrated in the frequency domain. The origin of unwanted sparkle components, scaling and offset in sparkle evaluation, and verification of the method are presented.

    1. On adjustment of stereo parameters in multiview synthesis for planar 3D displays

      Dongxiao Li, Xiaotian Qiao, Dongning Zang, Lianghao Wang and Ming Zhang

      Article first published online: 5 NOV 2015 | DOI: 10.1002/jsid.387

      Thumbnail image of graphical abstract

      This paper investigates the impacts of stereo parameters in multiview synthesis for planar 3D display and presents a novel parameter adjustment method for reducing visual discomforts and geometric distortions. The parameters are adjusted according to the comfortable viewing zone based on the depth of focus theory and user preferences.

      A reliable basis for multiview image synthesis and a more comfortable stereo perception can be achieved by applying the proposed method.

      Colloidal quantum dot-based light-emitting diodes have been demonstrated, which exhibit external quantum efficiencies (EQE) >10% for red, green, and blue (21% EQE, 82 cd/A for green). The devices have long lifetimes of >280k hours and extremely well-tuned color fidelity covering 170% of the National Television System Committee 1987 color space and 90% of the Rec. 2020 color space. In addition to the high efficiency and extremely pure colors, these devices are completely solution processed, making them a disruptive technology leading to next-generation displays.

    2. Highly reliable mobile liquid crystal display using AlOx deposited by atomic layer deposition for side sealing structure

      Article first published online: 3 NOV 2015 | DOI: 10.1002/jsid.390

      Thumbnail image of graphical abstract

      A side-sealing structure, including, outside a sealant, AlOx deposited using an atomic layer deposition apparatus, was employed for a low-frequency driving liquid crystal display with a bezel width of 0.7 mm. This side sealing structure can effectively prevent the entry of external moisture. Prevention of decrease in voltage holding ratio was confirmed. A narrow-bezel display with c-axis-aligned a-b-plane-anchored crystal In-Ga-Zn oxide backplane can have a long-term high reliability as a low-frequency driving display.

    3. An 81-in. 8 K OLED Kawara-type multidisplay with flexible displays that provides a seamless image

      Article first published online: 2 NOV 2015 | DOI: 10.1002/jsid.386

      Thumbnail image of graphical abstract

      We fabricated a Kawara-type multidisplay, providing a seamless image by precisely arranging 13.5-in. organic light-emitting diode flexible panels with transparent edges on two adjacent sides. To make overlapping portions less visible, the transparent regions were adjusted optically and corrected in luminance and chromaticity. We used 36 panels to fabricate an 81-in. 8 K organic light-emitting diode Kawara-type multidisplay.

      Article first published online: 2 NOV 2015 | DOI: 10.1002/jsid.392

      Thumbnail image of graphical abstract

      The inherent advantages of reflective e-paper displays – wide viewing direction range and excellent sunlight readability – can be extended into low-light conditions by adding an integrated lighting unit. A methodology for predicting the viewing direction dependence of ambient contrast and color from display measurements and illumination models is applied to e-paper displays with operating integrated lighting unit. The predictions can be used to optimize task lighting. Indoor performance of e-paper displays is improved without compromising their superior daylight performance.

    5. Nonuniform viewing angle of integral imaging display

      Article first published online: 27 OCT 2015 | DOI: 10.1002/jsid.385

      Thumbnail image of graphical abstract

      An integrated point appears at the cross section between collected rays and a lens array; the viewing angle of the integrated point is thus equal to the angle between the two farthest rays. This approach is useful to determine the viewing angle of all 3D displays, because a 3D point appears in the cross section of collected rays. The viewing angle depends on the position of the integrated point and is smaller than the viewing angle of the conventional calculation.

      This paper describes a visible light communication system with light emitting diodes that supports the audio applications at the short distance up to 80 cm and the data bandwidth of 32 kHz. The proposed simple CDR using a triple sampling scheme allows frequency offsets to be compensated for over the region from −1.5% to 1.5% without any complicated phase-locked loop blocks.
