FSTN LCD screen, liquid crystal display module

General Specification：FSTN (Film+STN), in order to improve the background color of the ordinary STN, a compensation film is added on the polarizer to eliminate the dispersion and realize black and white display.Can be made into blue, green, orange, yellow, and other colors of the screen background.The following are 160*160 parameters for reference:

Pin Connections

Pin No.	Pin Out	Description
1-2	NC	No connection.
3-4	VLCD	High voltage LCD Power Supply. When internal VLCD is used, connect these pins together. When external VLCD source is used, connect external VLCD source to VLCDIN, pins and leave VLCDOUT open.
5	VS+	LCD Bias Voltages. These are the voltage sources to provide SEG driving currents. These voltages are generated internally. Connect capacitors of CAX / CBX value between VAX+ / VBX+ and VAX– / VBX–, respectively.
6	VS-
7	VB0-
8	VB1-
9	VB1+
10	VB0+
11-12	VDD	Power supply for LCD circuit.
13-14	VSS	Ground.
15	BM0	Bus Mode: The interface bus mode is determined by BM0 with the following relationship: BM 0：Mode 1：6800/8-bit 0：8080/8-bit
16	CS0	Chip Selection. Chip is selected when CS0 = “L”. When the chip is not selected, DB [7:0] will be high impedance.
17	A0(CD)	Selects Control data or Display data for read/write operation. In S9 mode, CD pin is not used. Connect to VSS when not used. ”L”: Control data ”H”: Display data
18	WR1(RD)	WR[1:0] control the read/write operation of the host interface. See section Host Interface for more detail. In parallel mode, the meaning of WR[1:0] depends on whether the interface is in the 6800 mode or the 8080 mode. In serial interface modes, these two pins are not used, connect them to VSS.
19	WR0(WR)
20	RST	When RST=”L”, all control registers are re-initialized by their default states. Since UC1698u has built-in Power-ON reset and software reset commands, RST pin is not required for proper chip operation. An RC Filter has been included on-chip. There is no need for external RC noise filter. When RST is not used, connect the pin to VDD.
21	DB0	Bi-directional bus for parallel host interface.
22	DB1
23	DB2
24	DB3
25	DB4
26	DB5
27	DB6
28	DB7
