3-5. Function of Commands 3-5-1. Screen Display on / off Control (00H, 01H, 02H, 03H) The latest command becomes effective. At power on, screen 1 and 2 are set to Display off mode. Therefore, the Display on mode command should be written in, after display pattern data input. In case of executing Display on mode before display data input at initial, random pattern may be displayed. 3-5-2. Setting of Write Address Mode (04H, 05H) These commands select either the write or read address is incremented by single step automatically or is held after data write and data read. When a memory address is set to 090FH, next memory address is set to 0000H. 3-5-3. Data Write (08H) After executing the Write address setting command, this command shall be executed.

3-5-5. Setting of Display Start Address (0AH, 0BH, 0CH, 0DH) The display start address is just pointed to the left and top line of the display area. Screen 1 and 2 can be independently set the display start address each other. This address is divided to the two portions with upper (five bits) and lower (eight bits) address, and lower address shall be set first, then set the upper address. The smooth scroll of displaying can be achieved by synchronizing with the change of display address by the INT signal at every frame. The following indicate the display start address of screen1 to set to 023EH. C/ D CS

3-5-6. Setting of Write/Read Address (0EH, 0FH) This command is set the write/read address of displaying data. This address is divided the two portions with upper (five bits) and lower (eight bits) address, and lower address shall be set first, then set the upper address. Only the upper address is available to be changed independently. When the lower address is changed, it is required to change the both address. 3-5-7. Screen OR / EX-OR / AND Display Select (10H、11H、12H) The latest command becomes effective. 3-5-8. Luminance Adjustment (13H) Write-in data (00H～50H) allows luminance to be adjusted. When the module is turned on, it is set to dimming level 0%.
Input Data 00H 0AH 14H 1EH 28H 32H 3CH 46H 50H 64～FFH

Note1) Write-in data (64H～FFH)allows luminance to be 0%. Note2) Write-in data is available from 00H to 50H. Note3) Write-in data (51H～63H) prohibits.

8. CAUTIONS FOR OPERATION 8-1. Applying lower voltage than the specified may cause non activation for selected pixels. Conversely, higher voltage may cause non-selected pixel to be activated. If such a phenomenon is observed, check the voltage level of the power supply. 8-2. The DC/DC converter generates approximately 65Vdc, avoid touching it with bare hands, or to other circuits. 8-3. Avoid using the module where excessive noise interface is expected. Noise affects the interface signal and causes improper operation. Keep the length of the interface cable less than 30cm. (When the longer cable is required, please confirm there is no noise affection.) 8-4. When power is turned off, the capacitor will not discharge immediately. Avoid touching IC and others. The shorting of the mounted components within 30 sec., after power off, may cause damage. 8-5. When fixed pattern is displayed for a long time, you may see uneven luminance. It is recommended to change the display patterns sometimes in order to keep best display quality. 8-6. DC/DC converter is equipped on the module, the surge current may be approximately 5 times the specified supply current at the power on.
