8 ELECTRICAL CHARACTERISTICS
8.4 Analog Circuit Characteristics
LCD drive circuit
The typical values in the following LCD driver characteristics varies depending on the panel load (panel
size, number of display pixels and display contents), so evaluate them by connecting to the actually used
LCD panel. Refer to Section 8.8, "Characteristics Curves" for the load characteristic.
