Function specifications

Adjusting the Display Contrast

• This LCD module equipped with latest digital contrast adjustment function.
• Its display contrast could be adjusted by MCU command.(Please see the command tablesfor details)
• It is recommended to provide a contrast adjustment interface for end-user,where thebest display result could meet the individual preference in mass production.

Resetting the LCD module
The LCD module should be initialized by using /RST terminal. While turning on the VDD and VSS power supply, maintain /RST terminal at LOWlevel. After thepower supply stabilized, release the reset terminal (/RST=HIGH)

Display Memory Map

Note:

1. The above is based on:
   • Mirror Y direction; LC[2]=1
   • Normal X direction; LC[1]=0
2. For details please refer to UC1698 datasheet

Display Commands
The LCD module contains register, which control the operation. These register can be modified by commands.The following table is a summary of the control registers, their meaning and their default value

Register Table

• ‘     1
SL| 8| OH| Scroll Line. Scroll the displayed image up by SL rows. The valid SL value is between 0 (for no scrolling) and (159 – 2x(FLT+FLB)). Setting SL outside of this range causes undefined effect on the displayed image.
FLT
FLB| •t d| OH
OH| Fixed Lines. The first FLTx2 lines and the last FLBx2 lines (relative to CEN) of each frame are fixed and are not affected by scrolling (SL).When FLT andior FL8 are non-zero, the screen is effectively separated Into three regions: one scrollable, surrounded by two non-scrollable regions.When partial display mode is activated, the display of these 2xFLT and 2xFLB lines is also controlled by LCKII. When LC/01=1, the display will have three sections: 2xFLT on one side non-scrollable. 2xFLB on the other side also non-scrollable. and scrollable DST-DEN in the middle.

Design and Handling Precaution

1. The LCD panel is made by glass. Any mechanical shock (eg. dropping formhighplace)will damage the LCD module.
2. Do not add excessive force on the surface of the display, which may cause theDisplaycolor change abnormally.
3. The polarizer on the LCD is easily get scratched. If possible, do not remove theLCDprotective film until the last step of installation.
4. Never attempt to disassemble or rework the LCD module.
5. Only Clean the LCD with Isopropyl Alcohol or Ethyl Alcohol. Other solvents (eg. water)may damage the LCD.
6. When mounting the LCD module, make sure that it is free form twisting, warpinganddistortion.
7. Ensure to provide enough space (with cushion) between case and LCDpanel toprevent external force adding on it, or it may cause damage to the LCD or degrade thedisplayresult.
8. Only hold the LCD module by its side. Never hold LCD module by add force ontheheat seal or TAB.
9. Never add force to component of the LCD module. It may cause invisible damageor degrade of the reliability.
10. LCD module could be easily damaged by static electricity. Be careful to maintainanoptimum anti-static work environment to protect the LCD module.
11. 11. When peeling off the protective film from LCD, static charge may cause abnormal display pattern. It is normal and will resume to normal in a short while.
12. Take care and prevent get hurt by the LCD panel sharp edge.
13. Never operate the LCD module exceed the absolute maximum ratings.
14. Keep the signal line as short as possible to prevent noisy signal applying to LCDmodule.
15. Never apply signal to the LCD module without power supply.
16. IC chip (eg. TAB or COG) is sensitive to the light. Strong lighting environment couldpossibly cause malfunction. Light sealing structure casing is recommend.
17. LCD module reliability may be reduced by temperature shock.
18. When storing the LCD module, avoid exposure to the direct sunlight, high humidity, hightemperature or low temperature. They may damage or degrade the LCDmodule
