FPC Interface 128x64 COG LCD Module 12864 Dot Matrix LED

Product Details

I. Product Core Parameters and Technical Characteristics

1. Basic Specifications
Display Parameters: 128 columns × 64 rows dot matrix structure, typical pixel pitch 0.45mm × 0.45mm, display area approximately 57.6mm × 28.8mm (suitable for compact layout requirements of small devices); supports black and white single-color display, some models offer yellow-blue/yellow-green dual-color options.
Driver Scheme: Uses COG (Chip On Glass) packaging technology, bonding the driver IC directly onto the glass substrate, significantly reducing module thickness (typically ≤ 2.5mm) and volume, while reducing signal transmission loss and improving display stability.
Interface Type: FPC (Flexible Printed Circuit) interface, common pin count is 8-16 pins, supports two mainstream communication protocols (SPI/I2C) (some models are compatible with parallel interfaces), FPC cable length can be customized (conventional 10-30mm), meeting the wiring requirements for narrow installation spaces.
Backlight Configuration: Built-in LED backlight (side-emitting type), typical operating current 20-50mA, brightness ≥ 100cd/m², backlight lifespan ≥ 50,000 hours, supports low-power sleep mode (sleep current ≤ 1μA).
Operating Environment: Working temperature - 20℃~70℃, storage temperature - 30℃~80℃, meeting the wide temperature requirements for industrial and consumer electronics; working voltage 3.3V/5V dual voltage compatibility, power consumption ≤ 100mW (working state).

2. Core Technical Advantages
COG Packaging Advantage: Compared to traditional COB (Chip On Board) packaging, volume is reduced by 30% or more, weight is reduced by 40%, suitable for ultra-thin, lightweight device design; reduces welding points and connection lines, fault rate is reduced by 50%, improving product reliability.
FPC Interface Characteristics: Flexible cables can be bent and folded, suitable for irregular installation spaces, and the interface can be plugged and unplugged ≥ 1000 times, meeting the requirements for equipment assembly and maintenance; SPI/I2C interfaces only require 4-6 control lines, simplifying the motherboard circuit design.
Low Power Consumption Design: Static display mode power consumption is only 1/3 of dynamic display, combined with LED backlight dimming function, brightness can be adjusted according to usage scenarios, extending the battery-powered device's battery life.
