Typical values at 25 °C. Tolerances, pin assignment and timing are in the datasheet — ask for it before locking your PCB layout.
Price depends on quantity, touch option and packaging. Send the quantity and we quote the same working day where possible.
Mechanical drawing
Outline, active area position, FPC route and pin pitch. Dimensions in millimetres. Check this against your enclosure opening before you commit the mechanical design — it is free to change here and expensive to change after tooling.
Drawing carried over from our previous catalogue; some annotations are in Chinese. Ask us for the current 2D drawing (DWG or PDF) and we will send it with the datasheet.
Product description
Custom & OEM 2.9-Inch COG Monochrome LCD With 240×128 FSTN Dual Interface Versatility COG Dot Matrix Display
Definition and Principle
COG Dot Matrix Display refers to a type of display technology that uses a Chip - on - Glass (COG) packaging method for dot - matrix - style displays. Here is a detailed introduction:
Principle
It consists of a matrix - arranged array of pixels, and each pixel can be independently controlled to display different colors or grayscale levels. By controlling the on - off state and brightness of these pixels, various images, text, and graphics can be presented.
Product Key Features and Advantages
(1) FSTN Clarity for Monochrome Display:
2.9-inch FSTN dot matrix LCD (240×128 resolution, ash-colored) delivers high contrast and sharp text/graphic rendering, outperforming standard STN in readability—ideal for data-intensive applications (e.g., meters, gauges).
(2) Dual Interface Versatility:
Supports Parallel/Serial interfaces, enabling seamless integration with diverse microcontroller systems. Reduces design complexity for engineers building industrial, portable, or automotive devices.
(3) Rugged Environmental Endurance:
Operates in -20°C~+70°C (stores in -30°C~+80°C), surviving extreme temperatures (outdoor, industrial, automotive use). 40,000-hour LED backlight ensures long-term reliability.
(4)Compact COG Design:
Ultra-slim module (71.50×48.20×5.30mm) with COG (Chip-On-Glass) packaging saves space, suited to portable gadgets (e.g., handheld testers, wearable monitors) and space-constrained setups.
(5) Certified Quality & Compliance:
REACH & RoHS compliance ensures global market access (RoHS-compliant materials).

What this specification means in practice
TN glass is the cost-efficient choice with the fastest response. Contrast and colour shift once you move off the specified viewing direction, so it fits devices with a fixed operator position.
200 cd/m² suits indoor instruments and panel HMIs. If the device will sit outdoors or under direct light, ask us for the high-brightness version of this glass instead.
The UART/serial variant carries its own controller and command set, so your MCU sends text and commands instead of driving pixels. It cuts firmware work substantially.
Operating range -20°C to +70°C covers unheated cabinets, outdoor enclosures and cold-chain equipment. Standard commercial panels stop at 0 °C and go dark or slow in the cold.
Ordering and customisation
This model ships as a bare module by default. We commonly modify the FPC length and connector, change the backlight current, add a capacitive or resistive touch panel, or bond cover glass with your printing. Tell us the enclosure opening and the mounting method and we will confirm what can stay standard and what needs tooling.
Typical applications
Instrumentation & Metering
Power, gas and water meters that must run for years on a battery and stay readable in daylight.
Industrial Automation & HMI
Simple machine readouts where colour adds cost but no information.
How a customised order runs
Send the requirement
Size, resolution, interface, brightness, operating temperature, touch or no touch, and the annual quantity. A photo or drawing of the enclosure opening helps more than a long description.
We confirm feasibility and quote
You get a specific model number or a modification plan, with tooling cost and lead time stated separately from the unit price. Usually within one working day.
Sample and approval
Samples in 10-15 days from stock glass; custom glass or a new FPC adds tooling time. You approve dimensions, display quality and interface timing before mass production starts.
Production and shipment
10-20 days after specification freeze. Anti-static bag + foam tray + export carton, shipped DHL / FedEx / UPS express or by your forwarder. We keep the approved sample as the reference for every repeat order.
