Technology Trend • LCD displays on mobile phones, digital cameras and PDA's are moving to higher-resolution color displays. • CPU and microcontroller I/O voltages are decreasing and moving to 2.5-V and below as core operating voltages migrate to 1.8-V and lower. • The existing controllers for LCD panels in the market still operate from 3 to 3.6-V supply voltages. Similarly, the LCD module interface in the market also remains fixed at the 3.3-V logic level.
