Abstract
A digital-desk pilot program, named One Laptop Per Child (OPLC), in Brazil uses a unique display design to provide an interactive interface developed to enhance education and minimize ergonomic concerns. The one-to-one computer strategy as proposed by Nicholas Negroponte is a way of circumventing the tragedy of the locked computer lab because it gives children full access to computers anytime. The OLPC program has focused on a solution that minimizes power consumption, which also limits the display's maximum size and processor performance because the LCD backlights are responsible for a significant part of the power consumption in laptops. The government has also developed a new type of low-cost tablet that is based on a resistive principle. High transparencies can be obtained in the 90% range in the tablet, while robustness is guaranteed by the outstanding tribological characteristics of Sn02 on glass.
