For this reason some people argue that a computer screen is not suitable to read long articles.
[8] The main disadvantage of the mobile phone is it limited screen size which makes reading longer texts more difficult.
The development of beamers, specially designed to work with mobile phones, could provide a solution for this problem.

A liquid crystal display (LCD) is an electronically-modulated optical device shaped into a thin, flat panel made up of any number of color or monochrome pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector.
Many tiny cells between two panels of glass hold an inert mixture of noble gases.
The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light.
Electrowetting is now used in a wide range of applications from modulab to adjustable lenses, electronic displays and switches for optical fibers.
It is a proprietary material that is processed into a film for integration into electronic displays, particularly for E-book devices such as the Sony Reader, the iLiad, the Cybook Gen3, the Amazon Kindle, the Readius device from Polymer Vision[24] and Plastic Logic's Reader.
