and component aging) make LED displays expensive and relatively inefficient. Engineering solutions can cost-effectively rebalance an installed LED display. Also, current displays are not designed for optimized power efficiency, resulting in loss of energy efficiency and increased heat load. Automatic adjustment of the picture characteristics due to ambient parameters, use of more efficient power converters such as the electronic ballast, or other specific designed power supply will make the displays more energy efficient, thus reducing the heat generated. The primary objective will be achieved by first developing a team of experts from industry and academia to discuss problems and develop intelligent and inexpensive engineering solutions. The problems will be identified based on the needs of the industry, keeping in mind cost and durability. Collaborations will be developed between UNLV and the display and entertainment industry. The active industrial collaborators currently identified are Macon Gaming, Inc., Las Vegas; Video Walls USA, Inc., Las Vegas; and Tecnovision, Milan, Italy. Additional partners will be identified and included into the consortium as the project progresses. All industrial partners will provide in-kind cost-sharing through materials, components, testing facilities, and testing. Subtask 1: Organization. A technical workshop, consisting of faculty members and industrial partners, will be organized to develop engineering design solutions to identified problems and to plan for implementation of solutions. The subtask will be accomplished by (1) organizing a consortium of display industries and academic institutions; (2) conducting a series of workshops to identify problems; (3) identifying components and systems that will be given to the project by industrial partners; and (4) identifying testing facilities available to the project from industrial partners. the emission and emission patterns of various LEDs and (2) using the system to study the emission/emission patterns from LEDs of various colors and manufacturers. Subtask 3. New algorithms and electronic circuitry will be developed to achieve better color balance, with the final goal of developing a self-diagnostic and reconfigurable system. Specifically, they will allow the (1) study of the responses of various LEDs with respect to intensity and linearity; (2) development of different algorithms to achieve the necessary color balance dictated by the application; and (3) development, design, and build-out of electronic circuitry to achieve optimal performance with a view toward energy conservation. Subtask 4. New methods of remotely controlled current adjustment to achieve the desired overall brightness of the display will be investigated. This will by (1) studying the performance and energy efficiency of the displays under various ambient conditions and (2) developing an automatic feedback control system to respond to the ambient conditions to save energy. Subtask 5. Other possible LED configurations besides the classic red green blue (RGB), such as the use of a fourth white LED to increase the overall brightness and gray-scale linearity, will be studied. Subtask 6. New modifications in the photonics section with the use of virtual pixels to improve resolution, and in the processing section for faster refresh rate, signal processing, and distribution, will be developed. Variability of response of the human eye to the various visible wavelengths has allowed for deviating from the normal RGD LED containing pixels without sacrificing the perception by the human eye. This is done using the virtual pixel concept, wherein RG and BG are used instead of RBG and RGB. This will not only reduce the number of LEDs, but also save energy and cost. The objective is to study the quality of such displays, identify potential improvements, and then design and build better systems. Expected outcomes of the project are: A consortium of industrial and academic partners to collaborate in identifying and solving engineering problems with displays. • A prioritized list of display-related problems of great interest to the industry, with a view to achieving cost and energy efficiency. Subtask 2: System Development. A photometer system, based on video camera and solid-state sensors, will be developed to study and measure the emission of either the single LED or clusters. This is an important first step for the successful completion of future technical work. This will be used as part of the final automatic testing robotic system to test the whole display. As part of this • engineering work, various displays with different pixel spacing and indoor/outdoor use will be identified and cataloged for emission studies. The subtask will be accomplished by (1) designing and building the photometer system to reliably study EERE Crosscutting Activities 188PDF Image | DOE Solar Energy Technologies Program
