7 V0 Power supply for LCD drive
9 /WR Write Command or data to module when “L ” 11 /RD Read Command or data from module when “L ” 12,14,16 D S04~DS06 3bits to indicate the row being scanned: range 0 to 7 corresponding to RO W1 to ROW8 , with DS4 as LSB & DS6 as MSB. Outpu t is latched at the most recently touched position. When read while “TOUCH” is positive, the touched column is identified.* 13 /CE Enable L CD controller when “L ” 15 C//D Command/data select. “H” for command read/write. “L” for data read/write 17 /RST LCD Con troller reset. Controller initialize and DB0 0-DB07 are set to be high impedance when/RST is “L ” 18 //SCA N Active LOW : Standby to scan. Scanning will begin when a touch is identified at any of the sensing position, and will c ontinue until touch is removed. AZ Displays, Inc. Page 03

Note: It is only a draft drawing to show the components on the PC B. W e should update the drawing after the PC B sample is approved. AZ Displays, Inc. Page 05
DESCRIPTION: 7-1-1.The polarity of the pin 37 and the pin 39: LED Polarity symbol symbol state J3,J5 J6, J4 37 Pin 39 Pin J6,J4 Each solder-bridge Each closed Each open A node Cathode J3,J5 Each solder-bridge Each open Each closed Cathode A node Note: In application module, J3=J5 =J2=closed, J4=J6= open. 7-1-2. The J1 is metal-bezel GND to module GND and J7 is mounting holes GND to module GND. Note: In application module, J1= J7=closed 7-1-3.T he L E D resistor should be bridged when J2 is cl osed Note: In application module, J2=closed 7-1-4.T he R8 and the R9, R 10, R 11 are the LED resist or. Note: In application module, R8 = R 9= R 10= R 11=open
7.2 Example application
7-2-1. The LE D resistor should be bridged as following. 7-2-2. The 37 pin is the anode and the 39 pin is the cathode as following. 7-2-3.T he 37 pin is the cathode and the 39 pin is the anode as following. 7-2-4. The metal-bezel is on ground as following. R1 1 R 10 AZ Displays, Inc. Page 06

3). Pow er Supply ON/OFF Sequence ON Sequence OFF Sequence AZ Displays, Inc. Page 08
Please maintain the above sequence when turning on and off the power supply of the module. If VEE is su pplied to the module while internal altemate signal for L CD driving (M) is unstable or RESET is active, DC component will be supplied to the LC D panel. This may cause damage to the L CD module. 10. BACKLIG H T ELECTRICAL/ O PTICAL SPECIFICATIO NS
