7. Power ON/OFF Sequence To prevent the device damage from latch up, the power ON/OFF sequence shown below must be followed.

Power ON: (VCC, GND)→ (VDDA, VSSA) → (V1 to V10) Power OFF: (V1 to V10) )→ (VDDA, VSSA) → (VCC, GND)

7.1 Power ON Control for Auto Mode

The product has a power ON sequence control function. When power is ON, blanking data is output for 4-frames (default value) first, from the falling edge of the following VS signal. It can be defined in register R5 A_TIME [1:0].The blanking data would be gray level 255 for normally white panel.

Figure 12 7.2 Reset When Power On

The product is internally initialized by the global reset signal, RESETB. The reset input must be held low for at least 1ms after power is stable.

13. Handling Cautions 13.1 Mounting of module

a) Please power off the module when you connect the input/output connector. b) Please following the tear off direction as Figure19 to remove the protective film as slowly as

possible, so that electrostatic charge can be minimized.

Figure 19 13.2 Precautions in mounting

a) When metal part of the TFT-LCD module (shielding lid and rear case) is soiled, wipe it with soft dry cloth.

b) Wipe off water drops or finger grease immediately. Long contact with water may cause discoloration or spots.

c) TFT-LCD module uses glass which breaks or cracks easily if dropped or bumped on hard surface. Please handle with care.

d) Since CMOS LSI is used in the module. So take care of static electricity and earth yourself when handling.

13.3 Adjusting module

a) Adjusting volumes on the rear face of the module have been set optimally before shipment. b) Therefore, do not change any adjusted values. If adjusted values are changed, the specifications

described may not be satisfied.

13.4 Others a) Do not expose the module to direct sunlight or intensive ultraviolet rays for many hours. b) Store the module at a room temperature place. c) The voltage of beginning electric discharge may over the normal voltage because of leakage

current from approach conductor by to draw lump read lead line around.

d) If LCD panel breaks, it is possibly that the liquid crystal escapes from the panel. Avoid putting it into eyes or mouth. When liquid crystal sticks on hands, clothes or feet. Wash it out immediately with soap.

e) Observe all other precautionary requirements in handling general electronic components. f) Please adjust the voltage of common electrode as material of attachment by 1 module.
