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.

FAQ:
1. I want the LCD display 8 digits and the outline size is 65x30x2.8mm………?
Answer: No problem. Firstly, please kindly send us your specification/ drawing paper
If you have not the specification, you can also provide your samples; we will recommend the suitable one
if it is standard products. Or we can customize for you based on your own requirement.
2.This LCD is just what we want, but it is big size, do you have any smaller size? And the display content need to be changed a little.
Answer: For the segment type LCD module, if you need modify the outline size or display content,
a new LCD glass module is need. We have to open new tooling for you.
3. This LCD display is HTN type, but I want STN type,can you make?
Answer: That’s all right . we can change for you as per you request.
4. I want customize a new LCD module. Can you do?
Answer: Yes, we can. Please send your drawing paper. If you have not, please advise me the outline size
of the LCD display, display information( Glass thickness, Polarizer, Display Type, Connector mode,
Storage Temp. Operating Temp. Supply Voltage, Viewing direction, drive condition), we can customize for you.
5. What is leading time for tooling?
Answer: General speaking, it will cost 15 to 25 days after drawing paper confirmation and tooling charge payment,
we can report you the exact time when you confirm the drawing paper.
6. Can you send us samples for checking?
Answer: Yes,. Samples order is available.
