LM160160ECW LCD Module

LM160160ECW LCD Module User Manual

Basic Specifications

The LM160160ECW LCD Module is a FSTN, positive, transflective
display with a white LED backlight. The display data is represented
by dark gray and light gray colors when the display data is 1 and 0
respectively. The module has a 12H viewing angle and uses a 1/160
duty, 1/10 bias driving method.

The module requires fine contrast adjustment function for
optimal display result in the application design.

Mechanical Specifications

The outline dimension of the module is 83.8 x 76.0 x 9.6MAX
(mm).

Terminal Functions

Absolute Maximum Ratings

The LM160160ECW LCD Module has the following absolute maximum
ratings:

Any stresses exceeding the absolute maximum ratings may cause
substantial damage to the device. Functional operation of this
device at other conditions beyond those listed in the specification
is not implied and prolonged exposure to extreme conditions may
affect device reliability.

Product Usage Instructions

To use the LM160160ECW LCD Module, connect the module to the
host system using the terminal functions described above.

The module requires fine contrast adjustment function for
optimal display result in the application design.

The module has a 12H viewing angle and uses a 1/160 duty, 1/10
bias driving method.

The module has a white LED backlight and requires negative power
for LED backlight (BLK) and positive power for LED backlight
(BLA).

To initialize the module, set /RST to L. To run the module
normally, set /RST to H.

Use A0 to select whether to transfer Display Data (A0 = H) or
Control Data (A0 = L). Use /WR and /RD to latch data or instruction
into the LCD module or read data or status from the LCD module.

Use /CS to enable or disable access to the LCD module.

The 8-bit Data bus can be used for display data or instruction
data when /CS=H, D0~D7=High Impedance.

4. Function specifications
4.1 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 tables for
details) ­ It is recommended to provide a contrast adjustment interface for end-user,where the best
display result could meet the individual preference in mass production.
4.2 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 LOW level. After the power supply stabilized, release the reset terminal (/RST=HIGH)

5. Design and Handling Precaution
1. The LCD panel is made by glass. Any mechanical shock (eg. dropping form high place) will damage the LCD module.
2. Do not add excessive force on the surface of the display, which may cause the Display color change abnormally.
3. The polarizer on the LCD is easily get scratched. If possible, do not remove the LCD protective 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, warping and
distortion. 7. Ensure to provide enough space (with cushion) between case and LCD panel to prevent
external force adding on it, or it may cause damage to the LCD or degrade the display result. 8. Only hold the LCD module by its side. Never hold LCD module by add force on the heat seal or TAB. 9. Never add force to component of the LCD module. It may cause invisible damage or degrade of the reliability. 10. LCD module could be easily damaged by static electricity. Be careful to maintain an optimum anti-static work environment to protect the LCD module. 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 LCD module. 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 could possibly 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, high temperature or low temperature. They may damage or degrade the LCD module
