2-Phase Operation
A high-speed low-power output switching function is provided by dividing the horizontal period into 1st-
and 2nd-phase periods, where high output current operation and low output current operation are
alternately performed.
During the 1st-phase period, the specified voltage is applied to the LCD panel quickly with a low output
impedance of about 2.5 k
(high output current operation). Here, the applied voltage is selected by the
upper three bits of display data.
During the 2nd-phase period, a voltage is applied corresponding to the display data with an output
impedance of about 15 k
(low output current operation).
In general, since it is not required to secure the 1st phase in a 640
×
480-dot color panel (see the figure
below for assumed load condition), CL4 can be fixed low.
This function is effective when the panel load is large or when a horizontal period is short and gray scale
voltage must be applied quickly. For settings in the 1st-phase period, see note 4 in Electrical
Characteristics.
