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
High Performance 3.2 inches Character LCD Modules with Multiple Sizes, Colors & Interfaces Available
Definition
A Character LCD (Liquid Crystal Display) module is a display device designed to show alphanumeric characters, symbols, and simple icons. It uses predefined character patterns stored in its memory to form text-based information, typically arranged in rows and columns. Unlike graphic LCDs, character LCDs focus on presenting text rather than complex images or graphics.
Product Features and advantages
The 20-character, 4-line LCD with dimensions of 98 x 60 mm is a 16PIN product equipped with a 16P FPC, enabling easy and flexible integration into different devices.
Available in gray, blue, and yellow-green, and offers red, amber, and other backlighting choices, ensuring excellent contrast for clear viewing.
Our alphanumeric LCDs come in multiple models including 8x2, 16x1, 16x2, 16x4, 20x2, 20x4, 40x4, with backlights in white, blue, yellow, red, green, and amber, catering to various display needs.
6800, SPI, and I2C interfaces are provided, meeting diverse application requirements and making it compatible with different systems.
VATN displays feature wide viewing angles and high contrast, making them suitable for a broad range of applications.
Customizable 20*4LCDs are available, and we offer a full data sheet and technical support to meet your specific requirements.

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.
100 cd/m² is an indoor, low-power specification - typical for battery meters and handheld instruments where runtime matters more than brightness.
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
Industrial Automation & HMI
Status lines on controllers and drives - two or four rows of text is often the entire UI requirement.
Instrumentation & Metering
Bench equipment and test rigs where a standard 16x2 module keeps BOM cost and firmware effort minimal.
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.

Questions about this model
What is the minimum order quantity for the JM-2004C-00?
Samples are 5 pcs. Production MOQ is 100 pcs for this catalogue model and 1,000 pcs when the FPC, backlight or glass is modified.
How long is the lead time?
10-20 days for production quantities, 10-15 days for samples from stock glass. Custom tooling is quoted separately and confirmed in writing first.
Can this module be customised?
Yes - FPC length and pin order, connector type, backlight brightness and colour temperature, cover glass, touch panel and bonding method. See what is changeable.
Do you provide a datasheet and drawing?
Yes. Email hyd@szjunxian.com with the model number and we send the full datasheet, 2D drawing and, where relevant, the initial sample report.
Which interface should I choose for my board?
It depends on your host processor and target resolution. Our interface selection guide compares MCU, SPI, RGB, LVDS and MIPI by pin count, resolution ceiling and MCU load.
Packaging, shipping and trade terms
Packaging is anti-static bag + foam tray + export carton, shipped by DHL / FedEx / UPS express, air freight, sea freight. Trade terms EXW, FOB Shenzhen, CIF, payment T/T, L/C, PayPal.
Need this module with different parameters?
Most orders start from a catalogue model and change two or three parameters. Send us the differences you need and we will confirm feasibility, tooling and price.
