For mobile applications, there is a tradeoff between the amount of light generated by a transflective display and the size of the battery required. Customers have different views as to what is sufficient brightness. For example with PDAs, the requirements range from 50 nits to 100 nits. How much is enough?
If the primary objective is shelf appeal, then you might want the brightest display. The more typical objective is to provide a pleasing result in all the ambient light levels of anticipated use. Above a certain brightness level, contrast is perceived interchangeably with brightness. Therefore, high contrast displays help minimize the brightness required.
Sharp’s Advanced TFTs provide a good compromise in terms of power and brightness. They will look very pleasing at 50-100 nits and outperform other displays that do not have comparable contrast at 200-300 nits of brightness. For mobile displays that require the absolute minimum power consumption, such as cell phones, SHARP also offers ULC Power Control.
