3. PIN FUNCTIONS
3.1 Source Driver Control Pins
(1/2)
Pin Symbol
Pin Name
Pin Number I/O
Description
S1 to S244 Driver output
248 to 5
Output The D/A converted 64-gray-scale analog voltage is output.
OSEL = L: S1 to S244
OSEL = H: S3 to S242
OSEL
Driver output count
446
switching
Input
The output count can be selected. When OSEL = H, the unused
pins S1, S2, S243, S244 always become Hi-Z (high impedance).
OSEL = L: 244 outputs
OSEL = H: 240 outputs
DCK
Dot clock
484, 485
Input Dot clock signal
CKS
Dot clock inversion
452
Input
Inverts the active level of the dot clock.
CKS = L: Low active
CKS = H: High active
HSYNC
Horizontal sync signal
482, 483
Input
Horizontal sync signal input pin.
Do not input a width wider than the horizontal period as the width of
the HSYNC active level.
VSYNC
Vertical sync signal
481
Input Vertical sync signal input pin.
HSEG
HSYNC polarity selection 453
Input
Selects the active level of the HSYNC signal.
HSEG = L: Low active
HSEG = H: High active
VSEG
VSYNC polarity selection 454
Input
Selects the active level of the VSYNC signal.
VSEG = L: Low active
VSEG = H: High active
D00 to D05
D10 to D15
D20 to D25
Display data input
508 to 503
502 to 497
496 to 491
Input
The display data is input with a width of 18 bits, the gray scale data
(6 bits) by 3 dots (1 pixels).
DX0: LSB, DX5: MSB
SCLK
Serial clock input
475, 476
Input Clock pin of serial interface.
SO
Serial data output
479, 480 Output Data output pin of serial interface.
SI
Serial data input
477, 478
Input Data input pin of serial interface.
LCDCS
Serial interface chip select 473, 474
Input Chip select pin of serial interface.
SCLEG0,
SCLEG1
Serial clock mode
selection
451,
450
Input Mode select pin of serial clock. For details, refer to 4. REGISTERS
for explanation in serial interface .
VCSEL
COM amplitude output 447
fixing signal
Input
Fixes the VCOM output to L. When not using the VCOM output,
set VCSEL to L.
VCSEL = L: VCOM output fixed to L
VCSEL = H: VCOM signal output in accordance with POL signal
GAM
External γ -usage selection 448
Input
When the γ -correction power supply is input externally, switch
GAM to H. If two or more chips are used, be sure to input the γ -
correction power supply externally.
Figure 3−1 shows VCOM application example.
GAM = L: External γ -correction power supply not input
GAM = H: External γ -correction power supply input
