TOPWAY LM12864LFW 128x64 Graphic LCD Module

Product Description

The TOPWAY LM12864LFW is a high-performance STN, Negative, Transmissive graphic LCD module boasting a 128x64 pixel resolution. It delivers excellent visual clarity by displaying light gray active data against a deep blue background. Illuminated by a bright white LED backlight and equipped with built-in S6B0107/S6B0108 equivalent controllers, this LCD screen provides reliable graphic output for various electronics projects, industrial interfaces, and embedded systems.

Key Features

• 128x64 pixel graphic display resolution.
• STN Negative Transmissive display mode with a 6 o'clock (6H) viewing angle.
• High-contrast color scheme: light gray display data on a deep blue background.
• Integrated white LED backlight circuit powered by 4 LEDs.
• Built-in power booster circuit for generating LCD driving voltage (VOUT).
• Environmentally safe and RoHS compliant.

Technical Specifications

Operating Instructions / How to Use

1. Adjust Display Contrast: You must connect an external 25k to 50k Variable-Resistor (VR) to the module to control the contrast. Connect this resistor between the VDD, VO, and VOUT pins to provide a reference voltage to VO.
2. Hardware Reset: Initialize the LCD module by setting the /RST terminal to a low logic level when turning the power on. Keep the /RST pin low for a minimum reset time of 2.0us before raising it to a high state for normal running.
3. Basic Software Setup: To drive the LCD module correctly and ensure a normal display, issue the following instructions to both controllers at startup: set "Display start line (Z address) = 0" and "LCD Display = on".
4. Data Access: Note that the 128 columns are split into two sections. Use the CS1 pin (CS1=1) to enable access to the left side (first 64 columns) and the CS2 pin (CS2=1) to enable access to the right side (last 64 columns).
5. Cleaning: Only clean the LCD panel with Isopropyl Alcohol or Ethyl Alcohol, as other solvents like water may cause damage.

Safety Notes & Warnings

• The LCD panel is made of glass; any mechanical shock, such as dropping it from a high place, will damage the module.
• Do not apply excessive force to the surface of the display, as this may cause the display color to change abnormally.
• The LCD polarizer is easily scratched; do not remove the protective film until the final step of your installation.
• The LCD module can be easily damaged by static electricity; be sure to maintain an optimum anti-static work environment to protect the device.
• Never operate the LCD module in conditions that exceed the absolute maximum ratings (such as applying more than 7.0V to VDD), as this may cause substantial damage.
• Avoid storing the module in direct sunlight, high humidity, or extreme temperatures, which can degrade the module's reliability.
