Display Screen and Initialize Set The Display screen consists of 8,192 dots arranged as 128 by 64 dots. It is divided into 64 display area blocks of 16 by 8 dots each. Each display area block can be assigned to GRAM (Graphic mode) or DDRAM (Character mode) by the Display Area Set command. (9.5 Page #10) But, this is the version which has no Font ROM. Therefore, DDRAM is not available, all of display area block must be assigned to GRAM as the initialize setting, and this must be done when the module is powered up and also every time the reset is applied, because all display area blocks are set to DDRAM area as default setting. Initialize sequence is as follows; Initialize Set Start C/D=1 5FHex Display Clear Wait 1mS n=0 C/D=1 62Hex C/D=1 0nHex C/D=0 FFHex Data Write n=n+1 NO n=8? YES END 4 GU128X64-800B 8.1 Graphic Display (GRAM) GRAM consists of 16,384 bits arranged in 128 by 128 bit blocks with access is structured as 8 bits of vertical data. The detail of GRAM is as follows: GRAM Data Write Position Address X-Address 00 7FH D0 D1 D2 D3 D4 D5 D6 D7 0H 1H Y-Address 4H 0H 5H 1H 6H 2H 7H 3H 8H 128bit 3H 64bit 2H 9H AH BH CH DH EH FH GRAM Data Write Position Address (0H - FH) 128bit 5 GU128X64-800B 8.1 Cont'd GRAM Display Start Position Address X-Address Y-Address 00H 07H 08H 0FH 10H 17H 18H 1FH 20H 27H 28H 2FH 30H 37H 38H 3FH 40H 47H 48H 4FH 50H 57H 58H 5FH 60H 67H 68H 6FH 70H 77H 78H 7FH GRAM 0(X=00H, Y=00H) 0Layer H 1H 2H 3H 128bit D0 D1 D2 D3 D4 D5 D6 D7 64bit 00 7FH GRAM Layer 1(X=00H, Y=00H) 128bit GRAM Display Start Position Address (00H - 7FH) This module has 2 layers - Layer 0 and Layer 1. Each layer in this display consists of 128 by 64 dots. Display merging using these 2 layers can be done with the Display ON/OFF command. Refer to 9.2 on page # 8 for details. Layer 0 has an area of 128x64 dots that starts from top left point defined by the GRAM Start Position Address. The area of Layer 1 is the next 128x64 dots. When the value of the GRAM Start Position Address X overflow = 7FH, the next position goes to 00H. When the value of the GRAM Start Position Address Y overflow = 7FH, the next position goes to 00H. For example: If the GRAM Start Position Address is set as X=02H, Y=08H, the area of Layer 0 is as follows; X=02H,03H,04H......7FH,00H,01H Y=08H,09H............46H, 47H In this case, the area of Layer1 is as follows; X=02H,03H,04H......7FH,00H,01H Y=48H,49H............06H,07H 6 GU128X64-800B 9.

DDRAM (On/Off), GRAM (On/Off), DDRAM (reverse or normal modes), GRAM (reverse or normal modes) and display merge are selected by the 2nd Byte. Reverse mode toggles the representation of green in the foreground and black in the background to the exact opposite - green to back and black to the foreground. This is similar to the concept of reverse video. 1st Byte: MSB LSB 0 0 1 < --------------------------- > Command Select 0 L1 L0 * < --------- > Display Control Data L1= (1 OR 0) = L0= (1 OR 0) = * * Either a "0" or a "1" is acceptable GRAM Layer 1 (Active OR Inactive) GRAM Layer 0 (Active OR Inactive) 2nd Byte: MSB LSB 0 GS 0 GRV AND EXOR < --------------------------- ------------------- > Display Control Data * * * Either a "0" or a "1" is acceptable GS= (1 OR 0) Graphic Display Area (GRAM) = (On OR Off) GRV= (1 OR 0) Graphic Display Area (GRAM) = (Reverse OR Normal) DS="0", GS= "0": Stand-by mode 1st Byte 2nd Byte L1 L0 AND EXOR * * 1 1 0 0 * * 1 0 1 0 1 0 0 0 0 0 * 1 0 0 0 0 Action AND Display of Layer 1& 0 EXOR Display of Layer 1& 0 OR Display of Layer 1& 0 Only Layer1 selected for display Only Layer0 selected for display Graphic Display Off * Either a "0" or a "1" is acceptable 9.3 Brightness Set (C/D= "1") The Brightness level of the display screen can be scaled by the following four bit control. Please note that the brightness is consistent across the illuminated pixels. There is no scaling of individual pixels. The display self-initializes to 100% brightness.

This command should always be applied at power on or reset. In the period of 1mS following the issue of this command, the module requires internal processing and does not accept any commands. MSB LSB 0 1 0 1 G1C G0C 1 HM < --------------------------- > < ---------------------------- > Command Select Clear Control Code To clear the GRAM area, G1C or G0C bit must be asserted. By asserting HM bit, both data write position address and display start position address which selected by G1C, G0C, DC also be reset. HM = (1 or 0) equals (Initialize data write position address and display start position address or Not initialize). G1C= (1 or 0) equals (GRAM area 1 is cleared or GRAM area 1 not cleared) G0C= (1 or 0) equals (GRAM area 0 cleared or GRAM area 0 not cleared) GRAM area 1: X= 00H-7FH, Y=0H - 7H (Display data write position address) GRAM area 2: X= 00H-7FH, Y=8H - FH (Display data write position address) 9 GU128X64-800B 9.5 Display Area Set (C/D="1", only used for Initialize Set) This command sets the display area block as Graphic Display (GRAM) or Character display (DDRAM). But, this is version which has no Font ROM. Therefore, DDRAM is not available, all of display area block must be assigned to GRAM as the initialize setting, and this must be done when the module is powered up and also every time the reset is applied. Setup is performed by 3-byte command. 1st Byte: (C/D="1") Command Select MSB LSB 0 1 1 0 0 0 1 0 < ------------------------------------------------------------ > Command Select 2nd Byte: (C/D="1") Display Area Data Address Select MSB LSB 0 0 0 0 0 A2 A1 A0 < ------------------ > (0H - 7H) Display Area Data Address 3rd Byte: (C/D="0") Display Area Block Select MSB LSB 1 1 1 1 1 1 1 1 < ------------------------------------------------------------- > Display Data D0 to D7 = "1": D0 to D7 = "0": Graphic Display (GRAM) Character Display (DDRAM, Not available) Display area block is assigned as follows on a screen. 8 dot 16 dot D0 D4 D0 D4 D0 D4 D0 D4 D0 D4 D0 D4 D0 D4 D0 D4 D1 D5 D1 D5 D1 D5 D1 D5 D1 D5 D1 D5 D1 D5 D1 D5 D2 D6 D2 D6 D2 D6 D2 D6 D2 D6 D2 D6 D2 D6 D2 D6 D3 D7 D3 D7 D3 D7 D3 D7 D3 D7 D3 D7 D3 D7 D3 D7 0 1 2 3 4 5 6 7 Display Area Data Address (0 to 7H) 10 GU128X64-800B 9.6 GRAM Data Write position Address Set (Graphic Display) (C/D="1") This command specifies both X & Y data write position address. 9.6.1 GRAM Data Write Position X Address Set Data write position X address of GRAM expressed with 8 bits (00Hex-7FHex) is specified.

MSB LSB 1 0 0 0 < --------------------------- > Command Select * IGX IGY < ---------------- > * * Either a "0" or a "1" is acceptable Address Mode data IGX = "1" : X-Address +1(increment) when writing to GRAM.(It not affect to Y-Address.) IGX = "0" : GRAM X address fixed mode IGY = "1" : Y-Address +1(increment) when writing to GRAM.(It not affect to X-Address IGY = "0" : GRAM Y address fixed mode. 9.9 Address Read C/D ="1" This command reads both vertical and horizontal display start position addresses of GRAM (Refer to sect. 8 Display Screen and Initialize set on Page # 4). On the parallel interface, the data bus outputs the address until CSS goes high after the READY signal goes active (Parallel #1:RD=LOW, Parallel #2:R/W=HIGH). The Data bus becomes an input when other. On the serial interface, TXD outputs the data from SCK rising after command is issued until the CSS goes high. Refer to 10.Interface on Page #15. 1st Byte: MSB LSB 1 1 0 1 < --------------------------- > 0 1 * * * Either a "0" or a "1" is acceptable Command Select MSB LSB 2nd Byte: * VG6 VG5 VG4 VG3 VG2 VG1 VG0 (Read) 3rd Byte: HG7 HG6 HG5 HG4 HG3 HG2 HG1 HG0 (Read) < -------------------------------------------------------------- > Vertical & Horizontal display start position address (GRAM) VG0 to VG6: Vertical display start position address HG0 to HG7: Horizontal display start position address 12 GU128X64-800B 9.10 Data Write to Graphic Display(GRAM) (C/D="0") Can be written into GRAM by setting GRAM X or Y data write position address. Example: Writing "EA Hex" sets "D1, 3, 5, 6, 7 =1" and "D0, 2, 4 =0".

Outline Dimension 20 GU128X64-800B Notice for the Cautious Handling VFD Modules Handling and Usage Precautions: Please carefully follow the appropriate product application notes for proper usage, safety handling, and operation standards for maximum performance. [VFD tubes are made of glass] * Because the edges of the VFD glass-envelop are not smooth, it is necessary to handle carefully to avoid injuries to your hands * Please avoid breaking the VFD glass-envelop to prevent injury from sharp glass particles. * The tip of the exhaust pipe is fragile so avoid shock from impact. * It is recommended to allow sufficient open space surrounding the exhaust pipe to avoid possible damage. * Please design the PCB for the VFD-module within 0.3 mm warping tolerance to avoid any forces that may damage the display due to PCB distortion causing a breakdown of the electrical circuit leading to VFD failure. [High voltage] * Avoid touching conductive electrical parts, because the VFD-module uses high voltage exceeding 30100 volts. * Even when electric power is turned off, it may take more than one minute for the electrical current to discharge. [Cable connection] * Do not unplug the power and/or data cables of VFD-modules during operating condition because unrecoverable damage may result. * Sending input signals to the VFD-module during a power off condition sometimes causes I/O port damage. * It is recommended to use a 30 cm or shorter signal cable to prevent functional failures. [Electrostatic charge] * VFD-modules needs electrostatic free packaging and protection from electrostatic charges during handling and usage. [Structure] * During operation, VFD and VFD-modules generate heat. Please consider sufficient heat radiation dissipation using heat sink solutions. * We prefer to use UL grade materials or components in conjunction with VFD-modules. * Wrap and twist motion causes stress and may break VFDs & VFD modules. Please adhere to allowances within 0.3mm at the point of attachment. [Power] * Apply regulated power to the VFD-module within specified voltages to protect from failures. * Because some VFD-modules may consume in rush current equal to twice the typical current at power-on timing, we recommend using a sufficient power capability and quick starting of the power regulator. * VFD-module needs a specified voltage at the point of connection. Please use an adequate power cable to avoid a decrease in voltage. We also recommend inserting a power fuse for extra protection. [Operating consideration] * Illuminating phosphor will decrease in brightness during extended operation. If a fixed pattern illuminates for an extended period,( several hours), the phosphor efficiency will decrease compared to the non operating phosphor causing a non uniform brightness among pixels. Please consider programming the display patterns to use all phosphor segments evenly. Scrolling may be a consideration for a period of time to refresh the phosphor condition and improve even illumination to the pixels. * We recommend using a signal cable 30cm or less to avoid some possible disturbances to the signal. [Storage and operating environment] * Please use VFD-modules under the recommended specified environmental conditions. Salty, sulfur and dusty environments may damage the VFD-module even during storage. [Discard] * Some VFDs contain a small amount of cadmium in the phosphor and lead in the solder. When discarding VFDs or VFD-modules, please adhere to governmental related laws or regulations. [Others] * Although the VFD-module is designed to be protected from electrical noise, please plan your circuitry to exclude as much noise as possible. * Do not reconstruct or repair the VFD-module without our authorization. We cannot assure the quality or reliability of unauthorized reconstructed VFD-modules. Notice: We do not authorize the use of any patents that may be inherent in these specifications. Neither whole nor partial copying of these specifications are permitted without our approval. If necessary , please ask for assistance from our sales consultant.
