| Abstract | System-on-chip (SoC) mobile thin-film transistor (TFT) liquid-crystal display (LCD) drivers are, to a certain extent, inadequate to support portable devices that require higher driving currents for their high resolution and large LCD panels. In this paper, we will show how a simple boost converter can be designed and used in the display driver for high current demand TFT-LCD panels. The proposed driver circuit is partitioned in a way that the current chip-on-grass (COG) package technology used by the traditional mobile display driver can be maintained in order to save production cost. A prototype of the controller of the proposed power converter is designed with a standard 0.13-µm HV CMOS process. Compared with traditional designs, the proposed circuit shows its support on higher output currents with improved power efficiency and output voltage variation. |

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.
