Pin No.	Symbol	Function
1-2	LED_A	Backlight LED Power
3-4	LED_K	Backlight LED Ground
5	GND	Ground
6	VCOM	Common voltage (3.5V)
7	DVDD	Power for Digital Circuit (3.3V)
8	MODE	DE/SYNC mode selectMODE=1，DE mode；MODE=0，HSD/VSD mode；
9	DE	Data Enable Input.Active High to enable the data input bus under “DE MODE”.Normally pull low.
10	VSYNC	Vertical Sync Input for TTL mode.
11	HSYNC	Horizontal Sync Input for TTL mode.HSD=0,8bit;HSD=1,6bit
12-19	B7-B0	Blue Data Bit
20-27	G7-G0	Green Data Bit
28-35	R7-R0	Red Data Bit / DX0-DX7
36	GND	Ground
37	DCLK	Dot Data Clock.Select by “IFSEL” pin. TTL input mode IFSEL=0
38	GND	Ground
39	L/R	Left/Right selectionSHLR=0，shift left: last data=S1←S2←S3……←S1536=first data；SHLR=1，shift left: first data=S1→S2→S3……→S1536=fast data；
40	U/D	Up/Down selectionUPDN=0,STV2 output vertical start pulse and UD pin output logical “0” to Gate drive.UPDN=1,STV1 output vertical start pulse and UD pin output logical “1” to Gate drive.
41	VGH	Gate ON Voltage (18V)
42	VGL	Gate OFF Voltage (-6V)
43	AVDD	Power for Analog Circuit (9.6V)
44	RESET	global reset pin. Active low to enter reset state. suggest to connecting with an RC reset circuit for stability. Normally pull high.
