In existing state-of-the-art methods, the optimal decision for clipping point is made only with consideration of current frame, and the target frame PSNR are set the same for all frames. Therefore they have the same power-PSNR performance. In the proposed work, we show that better power-PSNR performance can be achieved by assigning different target frame PSNR for different frames. In the proposed algorithm, the decisions for clipping points associated with all frames are made at once. The inefficiency ratio of each clipping point is evaluated and put into the algorithm design. An optimization problem is formulated, and a solution-search procedure is proposed. Compared with state-of-the-art methods, the proposed work performs better in both aspects of power and PSNR; the BD-PSNR and the BD-Power of the proposed work against all other methods are better for every tested video; the BD-PSNR and the BD-Power can be as high as 19.80 dB on average, and the BD-Power can be as low as - 26.25% on average.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1506-1513"},"PeriodicalIF":0.0,"publicationDate":"2016-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2622063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50306580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The periodic nanodisc arrays were elaborately designed by the Bragg diffraction and the maximum transmittance of a model of bilayer film on a GaN epitaxial layer. In the experiment, the periodic ITO nanodisc arrays have been fabricated by polystyrene nanosphere lithography. The electroluminescence intensity of the LEDs with periodic ITO nanodisc arrays is better than that of conventional planar GaN-based LED, and the greatest enhancement could increase the intensity by a factor of 2.08 at an operating current of 20 mA compared with the conventional planar GaN-based LED. The simulation results based on three-dimensional finite difference time-domain method showed that the LED with periodic ITO nanodisc arrays can improve the light-extraction efficiency of LED by enhancing the critical angle of light output. This method would be valuable for the fabrication of high-efficiency planar GaN-based LEDs.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1588-1593"},"PeriodicalIF":0.0,"publicationDate":"2016-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2621138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50409447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The requisite resolution and aspect ratio can be obtained by combining the appropriate LED panels. However, using different types of LED panels require using different types of LED controllers to drive them, which constitutes a rather burdensome design constraint. In addition, a driving circuit inside an LED panel may be modified to improve the display quality by adopting a new driving scheme or new LED elements. Furthermore, it may sometimes be necessary to create a completely new LED panel. All of these situations require the design of new LED controllers. In this paper, we, therefore, propose a configurable LED controller that can be used with various types of LED panels without requiring hardware modification or redesign. The proposed LED controller consists of an application-specific instruction-set processor (ASIP) and custom hardware. The ASIP is software programmable, and the custom hardware is employed to obtain a high operating speed. Moreover, the function of the custom hardware can be configured through the ASIP software program for generating the necessary address sequence to read the image bit plane memory and, consequently, to accommodate the target LED panel. Therefore, the proposed LED controller provides the advantages of flexibility and high-speed operation. The proposed LED controller was implemented using Xilinx Virtex-5, and it successfully drove LED panels having 64 × 96, 96 × 80, and 128 × 64 pixels at refresh rates of 3125, 2232, and 1736 Hz, respectively. An analysis of the operational capability indicates that, at the same refresh rate, the field-programmable gate array prototype of the proposed controller drives 1.44 times more pixels per unit time than a state-of-the-art commercial controller.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1594-1601"},"PeriodicalIF":0.0,"publicationDate":"2016-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2621009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50409448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, we constructed a novel facial expression database regarding the visual discomfort. While viewing the realistic stereoscopic stimuli with screen disparities varying from 0° to 4.66°, each viewer's face was captured. The database consisted of face videos and associated comfort scores obtained by self-reporting, which might be only a publicly available database regarding the facial expressions associated with visual discomfort. Using the database, for the quantitative investigation, the facial expressions associated with visual discomfort were compared with basic emotional expressions that were well defined and universal. As a result, we observed that the emotional expression of “stressed” (i.e., anger or disgust) was highly correlated with the perceived visual discomfort (Pearson correlation coefficient: 0.91). Furthermore, the feasibility of the discomfort measurement using facial expressions obtained while viewing S3D contents was verified. Experimental results showed that the discomfort measurement using facial expression recognition could achieve a feasible performance (classification accuracy of 81.42%).","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1785-1797"},"PeriodicalIF":0.0,"publicationDate":"2016-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2616419","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50283227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
