Spectral models have been separately developed for the optimization process after experimentally measuring spectral power distributions of phosphor materials and semiconductor chips. By filtering billions of defective spectral data with a nonlinear program, optimal values of LE of 272 lm/W and CRI of 96 (CRI No.9 of 98) at a correlated color temperature of 2000 K can be achieved, while LE and CRI are 0.1 lm/W and 83 for candles. These three-humps LEDs are capable of achieving excellent photometric and chromatic performances of candle-like white light. Finally, this study can serve as a critical guide for manufacturing high-CRI candle-like white LEDs.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 11","pages":"1393-1397"},"PeriodicalIF":0.0,"publicationDate":"2016-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2598861","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50281341","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}

Here, touch interactivity is processed as an image, which is downsampled and reconstructed to estimate the touch position. After the reconstruction, a regional scan is performed around the reconstructed touch location to retrieve accurate touch information. Based on experimental and simulation results, we successfully decreased readout time and power consumption by 11.3 ms (68%) and 8.79 mW (68.7%), respectively, when only 25% sensors were selected. The presented technique yields higher responsivity and lower power consumption while maintaining detection accuracy.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 11","pages":"1417-1422"},"PeriodicalIF":0.0,"publicationDate":"2016-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2599001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50400089","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}

This touchpad detects finger contact by sensing the change in effective capacitance caused by the skin electrical impedance. A low-cost flexible disposable touchpad with nine capacitive buttons is fabricated, using paper as a substrate. The use of home inkjet printing technology with silver nanoparticle ink makes the fabrication process simple, fast, cheap, and environmentally friendly. The performance of the proposed touchpad is measured with a microcontroller, and tests are conducted for both the cases of finger and touch pen operation. The measured capacitance of the non-touched state is 228-236 pF, whereas the measured capacitance of the touched state is 340-564 pF. The differences in the capacitance of each state are sufficiently large to indicate that a finger has made contact with the touchpad. The sensitivity of the proposed sensor is evaluated, and the parameters of the proposed sensor are compared with those of other paper-based touch pads.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 11","pages":"1411-1416"},"PeriodicalIF":0.0,"publicationDate":"2016-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2598847","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50400091","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}

Display performances of proposed displays were analyzed. We fabricated two 360° display prototypes based on the n-gonal pyramidal mirrors assemblage and flat 3D displays. Moreover, we evaluated our proposed methods by simulations and experiments. Experimental results as well as simulation results were consistent with theoretical analysis based on the geometric optics.

We introduce a weighted average optimization to the image synthesis process, aiming to tradeoff the reconstructed depth range and the image sharpness without changing the hardware configuration, particularly for multi-projector-type light field displays. The proposed optimization evaluates the lost angular information and reallocates them in the rendering process. The RMSE evaluation on the optimization performance is implemented. The experimental results show that after the optimization the display offers more accurate reconstruction than before. Besides, a subjective experiment is implemented to further validate the effectiveness of the optimization. We envision this optimization being applied to various multi-projector-type light field displays, despite of the arrangement of projectors and the shape of the screen.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1745-1751"},"PeriodicalIF":0.0,"publicationDate":"2016-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2598059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50283220","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}
