For the signal output timing, refer to 5.4 Display Timing Generator.

CLK output for gate 446

Output This pin is the CLK output for the gate driver.

driver

Connect this pin to the CLK pin of the gate driver.

DC/DC converter

499

Output DC/DC converter ON/OFF control of power supply IC

control

Connect this pinto the DCON pin of the power-supply IC.

Regulator control

500

Output Regulator ON/OFF control of power supply IC

Connect this pin to the RGONP pin of the power-supply IC.

Regulator control

443

Output Regulator ON/OFF control of gate driver IC

Connect this pin to the RGONG pin of the gate driver.

VDD1 booster select

502, 503 Output Control signal to select x4/x5/x6/x7 booster of power supply IC for VDD1.

Connect this pin to the VCD11 and VCD12 pins of the power-supply IC.

VDD2 booster select

504

Output Control signal to select x2/x3 booster of power supply IC for VDD2.

Connect this pin to the VCD2 pin of the power-supply IC.

VO level select

505

Output Signal for selecting the level of the power supply IC booster voltage, to be
