CXA2112 Sony Corporation, CXA2112 Datasheet - Page 13

• Manufacturer Part Number: CXA2112
• Description: LCD Driver
• Manufacturer: Sony Corporation

The SID output is prepared for the Sony LCD panel's (LCX017 and LCX016) uniformity improvement signal
input (Psig input). SID_OUT does not have the capability to drive those pins directly. Connect via a buffer.
3. VCOM
VCOM generates the DC voltage applied to the Sony LCD panel COM electrode. VCOMOUT (Pin 33) voltage
is set as the deviation relative to SIGCEN voltage.
When VCOMOFST (Pin 34) is changed from 0 to 10V, VCOMOUT changes from (SIGCEN potential) to
(SIGCEN potential) – 2V.
