COG Graphic & Character LCD Modules
We make COG LCDs in our own factory — 128×64 graphic modules and 16×2 / 20×2 character types. ST7565 and ST7032 controllers, I2C / SPI / MCU interfaces, rated −20°C to +70°C. In stock from $9.90, no MOQ. We'll quote you within 24 hours.

What We Make
Five production COG modules. Grab one piece to test or ten thousand for your line — every unit goes through optical and electrical inspection before we pack it.

All five rated −20°C to +70°C with white LED backlight; datasheet and mechanical drawing on every product page. Need 128×64, 240×64 or 320×240? See the graphic LCD collection or ask an engineer.
Datasheet, unit pricing, volume tiers, and lead time — all in one email, back within 24 hours.
Why We Use COG
Driver IC bonded on the glass — no PCB bezel. The 20×2 module outline is 74.2 × 25.2 × 6.3 mm.
The 3.18″ 128×64 SPI module draws 147 µA max at 3.3 V — built for battery-powered instruments.
The FPC tail lands straight on your board — no headers, no bezel hardware, faster assembly.
FSTN transflective glass: readable with backlight off, white LED on at night, −20°C to +70°C.
Custom Work
A standard module gets you 90% there. We handle the last 10% — or start from your drawing and build a full custom COG.
How We Work
Send your drawing — datasheet and quote within 24 hours.
Samples from stock, or EVT custom samples with init code.
Drawing, interface timing and firmware confirmed together.
Cleanroom COG bonding and automated FPC integration.
EOL notice, second-source options and re-order support.
About Our Factory
COG bonding is what keeps a module working in the field. We do it in-house, in our own cleanroom — we don't outsource this part.
Particle-controlled assembly for bonding and lamination.
Driver IC aligned and bonded directly onto the glass.
Tail attachment and connector assembly under process control.
Luminance, chromaticity and dead pixels — every module.

Quick Answers
There is no MOQ on standard COG modules — order a single piece for evaluation. Samples ship from stock, and volume discounts start at 10 pieces.
Quotes come back within 24 hours (Mon–Fri 9:00–17:00, UTC+8). Standard samples ship from stock immediately; factory bulk lead time is about 3 weeks. DHL/UPS express delivers in 3–5 business days and is free over $800.
Send the part number or drawing. We match outline, pinout, controller and interface from our catalog — 128×64 to 320×240 graphic and 8×2 to 40×4 character — or build a pin-compatible custom COG. Evaluation samples and a quote come back within 24 hours.
Yes. We modify FPC shape and connector position, cover glass, and backlight, and we match I2C, SPI, 8080/6800 MCU and other host interfaces. Adapter and driver boards plus initialization code and bring-up support are available for custom builds.
You can return or exchange a module within 5 working days of receipt, and faulty products are replaced within 30 days. Every module passes optical and electrical inspection — luminance, chromaticity and dead pixels — before shipment.
Discounts apply by quantity: 5% at 10–49 pieces, 10% at 50–199, 15% at 200–499 and 20% at 500 or more. For larger or recurring programs, contact us for a volume pricing agreement.
