Custom COB LCD Module Manufacturer
Character and graphic LCD modules with Chip-on-Board packaging. Standard models 1602, 2004, 0802, and 12864 — plus full customization for industrial, medical, and consumer applications.
COB LCD Modules We Build
Standard character and graphic modules in multiple sizes, backlight colors, and interface options.
Find the Right Type and Model
First choose the technology type, then pick the exact model for your application.
Step 1 — Choose the Display Type
COB Module
Driver IC bonded on PCB. Higher reliability, better for harsh environments. Standard models widely available.
- • Character display (16×2, 20×4)
- • Graphic display (128×64)
- • Industrial and medical equipment
- • Vibration / temperature cycling
COG Module
Driver IC bonded directly on glass. Thinner, lighter, and more compact — ideal for slim devices.
- • Space-constrained products
- • Wearables and handheld devices
- • Slim industrial panels
- • High volume production
Segment LCD
Fixed-segment display with custom icons. Lowest cost, lowest power consumption.
- • Numeric meters and gauges
- • Battery-powered devices
- • Fixed icon layouts
- • High volume cost-sensitive
Step 2 — Choose the Model
1602 LCD Module
- 16 chars × 2 lines
- ST7066 / AIP31066

Interface & Driving — For Design Engineers
16-Pin Parallel Interface
Standard HD44780-compatible parallel interface. 8-bit or 4-bit data mode selectable.
I2C Adapter Available
Optional I2C adapter reduces pin count from 16 to 4 (VCC, GND, SDA, SCL). Ideal for MCU with limited GPIO.
Driver IC Firmware Support
ST7066, AIP31066, and ST7920 compatible. Reference initialization code and driver examples available.
Custom Pin Assignment
Need a different pinout to fit your existing PCB footprint? We can customize pin mapping for volume orders.
Multi-Voltage Support
3.3V and 5.0V versions available. Level-shifter not required for most 3.3V MCUs with 5V modules.
Engineering Support
Direct engineer-to-engineer communication. Send your schematic and we'll review compatibility.
