Increasing nitrogen flow rate as well as oxygen flow rate can reduce the carrier concentration and shift turn on voltage to the positive direction, indicating that nitrogen can be a good carrier suppressor of the TSO channel layer. The oxygen vacancies can be filled with nitrogen atoms resulting in less electron donors. Correspondingly, the mobility decreases due to the percolation conduction model. Besides, the TSO channel layer is amorphous regardless of nitrogen flow rate, which is important to ensure uniformity of oxide TFTs.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1560-1564"},"PeriodicalIF":0.0,"publicationDate":"2016-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2614328","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50306514","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 total distributions of the electrical field intensities were summed by all the fields of the related slices. In this paper, the precision of our analytical method will be examined for a diamond and a triangular patterns by the self or mutual driving method.

The investigation of an improved electrophoretic deposition (EPD) method of conformal phosphor coating for pc-WLEDs packaging is presented in this paper. The antimony tin oxide (ATO) nanoparticles were used to coat surface of LED chips array to achieve an evenly distributed transparent conductive layer as electrode (i.e., cathode for EPD process) by the spray technique. A kind of dispersant was added into the suspension of prepared phosphor particles to improve the stability. The experimental measurement reveals that a sort of compact uniform distribution of the phosphor layer surrounding the LED chips' surface was realized with this newly developed EPD method. And the standard deviation of correlated color temperature (CCT) and luminous efficiency are 256.03 K and 3.06 lm/W, respectively. The prototype of phosphor coating on a multchip array scale demonstrates that a Wafer Level Chip Scale Packaging (WLCSP) for white pc-LEDs can be achieved with the improved EPD method in this work.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1609-1612"},"PeriodicalIF":0.0,"publicationDate":"2016-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2614260","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50283215","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 proposed system is composed of an ordinary flat backlight, an edge-lit LGP, and a liquid crystal display panel. The edge-lit LGP is an acrylic sheet edge illuminated with light-emitting diodes (LEDs), and there is a diffuser dot array at the bottom. A point light source array for 3D mode is created by the LGP. The light rays from each point light source are modulated by each elemental image to integrate 3D images. In 2D mode, the flat backlight behind the transparent LGP is turned on while edge-lit LEDs are turned off at the meantime. The 2D and the 3D display modes can be simply switched from one to another by turning on different light sources.

This paper demonstrates the process of creating interactive printed smart fabrics suitable for a broad range of applications. In order to control the display, a series of tracks were printed that are 400 μm wide with a pitch of 1 mm; these dimensions are lower than the previously reported literature for connections to an EL lamp. An optimized design for a bus bar layer is designed, modeled, and tested. The design improvement reduces the amount of the emitting area covered by an opaque conductor and is shown to have no negative impact on the function of the EL lamp. The design for the EL watch display includes 28 EL lamps on fabric forming four seven-segment displays. The display is the first demonstration of multiple EL seven-segment displays on fabric. The brightness is characterized and compared to commercially available blue EL lamps. The watch segments had similar brightness to commercially available lamps.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 12","pages":"1757-1763"},"PeriodicalIF":0.0,"publicationDate":"2016-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2613906","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50305998","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}

Relationship between the 2D uniformity and anisotropy factor as well as mean free path is obtained by a series of simulation cases. The uniformity reaches over 85% in simulation. As well, a two-viewpoint prototype is built to give the experimental result. Measurements show that a highly transparent PDLC film can maintain the high-quality 3D performance while a strongly diffusive one can enhance the uniformity in 2D mode. By increasing the driving duty cycle of the backlight units, the issue of luminance attenuation in 2D mode can be addressed.
