To increase the reporting rate of a touch panel, the proposed circuit can be used to pause display operations to perform touch sensing operations several times per frame. The proposed circuit exploits a pre-charge structure that alleviates the leakage current and long-term stress of a driving TFT during the touch sensing operation. Simulation results confirm that the proposed gate driver circuit can generate a highly uniform output waveform after each touch sensing operation that lasts for 200 μs when the circuit is operate at 85 °C. The variations of the rising and falling time are suppressed below 3.71%, confirming the feasibility of use of the proposed gate driver circuit for an in-cell touch panel.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 11","pages":"1238-1241"},"PeriodicalIF":0.0,"publicationDate":"2016-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2601948","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50399945","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 spectral studies performed in the codoped phosphor upon 980 nm excitation emit radiations within the UV- NIR wavelength region. Diffuse reflectance and Fourier transform infrared (FTIR) analysis have been done to identify the presence of active ions and impurities in the prepared phosphor. The pump power dependence study results in green to red intensity ratio variation and thus a tuning in color of emitted light is observed. The observed emissions have been explained on the basis of excited state absorption (ESA), energy transfer (ET), and temporal evolution analysis.

However, 3D displays as physical (optical) information systems should have the fundamental classification criteria. Such criteria are introduced in this paper in the form of physical-information modalities (further - modalities) identifying the physical-information formats of 3D image recordings in the working media of 3D displays. The modalities are based on four physical-information categories defined as four possible combinations of two kinds of 3D scene data representation (the object O representation and the representation by angular spectrum S of spherical waves) and two physical forms of each representation implementation (the ray optics R and diffraction optics D concepts). The modality of 3D display defines the primary physical-information properties of 3D image recording in the working medium. The true 3D image properties follow from the primary ones taking into account the relevant psychophysiological properties of the human visual system. The human visual system directly perceives 3D image light distribution that have passed through the optical scheme of 3D display after exiting the working medium. The limits of the proposed theory are discussed.","PeriodicalId":15588,"journal":{"name":"Journal of Display Technology","volume":"12 11","pages":"1344-1351"},"PeriodicalIF":0.0,"publicationDate":"2016-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/JDT.2016.2600640","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50281347","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}
