Mobile displays have transformed from the early, simple alphanumeric and monochromatic passive-matrix LCDs to full-video-capable multimedia displays that boast some of the leading characteristics in displays found today. The increasing demand for space savings, robustness, reduced power consumption, and improved image quality in an environment of rapid cost erosion presents trade-offs that are difficult to solve for any display provider - yet the market is booming. This is due to the proliferation of mobile phones in all markets worldwide, including previously inaccessible third-world countries where a mobile infrastructure is rapidly being deployed. In the developed countries, mobile multimedia delivery to cell phones has become a hit. Multimedia in this context includes music videos, TV broadcasts, movies, and navigation applications, all of which demand high image quality on the display under various ambient-lighting environments. The entry point for many of these services is the Internet, and to access Web pages comfortably, highly legible displays are required. The entire mobile user interface is therefore a major focus of development, as can be seen in products that are coming out from major manufacturers. These include devices with touch screens and other advanced interaction capabilities.
