Product description
Custom 3.3V/5.0V Character LCD Modules Monochrome Characters Screen and Multiple Sizes
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
2.1 Diverse Sizes & Specifications: Available in various sizes including 8x2, 16x1, 16x2, 16x4, 20x2, 20x4, and 40x4 LCD options, catering to different display requirements.
2.2 Rich Color Choices: Comes in blue and yellow - green base colors, with backlighting options of red, amber, red, white, blue, yellow, green, and amber for enhanced visibility.
2.3 Standard Form Factor: Features a form factor of 98 x 60 mm, making it suitable for a wide range of installations.
2.4 Multiple Interface Options: Offers 6800, SPI, and I2C interfaces to meet diverse customer needs for seamless integration.
2.5 Specialized Display Type: Provides VATN displays with a wide viewing angle and high contrast, ideal for various applications.
2.6 16 - PIN Design: A 16PIN product, which is convenient for circuit connection and assembly.
Advantages
- Cost-Effective: More affordable compared to graphic LCDs, making them a budget-friendly choice for applications where simple text display suffices.
- Ease of Use: Simple programming and operation; developers can quickly implement text display functions without complex graphics processing.
- Reliability: Long lifespan and stable performance, with resistance to shock and vibration, reducing maintenance needs.
- Widely Available: A mature technology with numerous manufacturers, ensuring easy access to components and technical support.

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.
Touch is optional on this module. We bond capacitive or resistive panels to the same glass, so you can start without touch and add it on a later revision.
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 JM2004A?
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.
