APPLICATION INFORMATION
The requirements on the number of gamma correction
channels vary greatly from panel to panel. Therefore,
the BUF11705 series of gamma correction buffer offers
different channel combinations using 10 gamma
channels plus one V
COM
channel. The V
COM
channel
can be used to drive the V
COM
node on the LCD panel.
Gamma correction voltages are often generated using
a simple resistor ladder, as shown in Figure 21. The
BUF11705 buffers the various nodes on the gamma
correction resistor ladder. The low output impedance of
the BUF11705 forces the external gamma correction
voltage on the respective reference node of the LCD
source driver. Figure 21 shows an example of the
BUF11705 in a typical block diagram driving an LCD
source driver with 10-channel gamma correction
reference inputs.
