| Abstract | Field emission displays (FED) are based on a large array of individually switched electron sources. A major problem in such displays is intra-pixel uniformity. In particular, the eye is very sensitive to variations in spot shape even if pixel intensities are uniform. A second problem lies in visually unacceptable charging artifacts from the spacers, required to support the vacuum envelope. Incorporating hop and flue plates into the FED structure effectively removes these problems and has other advantages, such as improving colour purity. The glass hop plate (~0.4mm thick) has an array of conical holes; one for each sub-pixel. The electrons are channeled through the holes in a chaotic manner, resulting from secondary emission and surface charging, producing a virtual source of electrons that is independent of the shape of the original source. The electrons then pass into the inverted flue plate cones and are accelerated towards the anode. Spacing nibs on one plate leave a pumping space between the two plates. A non-evaporable getter layer between the plates can provide pumping after sealing. The dimensions and coating of the holes in the hop plate are optimized for providing a uniform virtual source, while those of the flue plate have to provide maximum voltage hold off to allow as high an anode voltage as possible |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
