BBI Monochrome LCD Display STN / FSTN LCD, Bezel, Zebra And PCB
The STN/FSTN monochrome liquid crystal display is a passive matrix display module based on super-twisted nematic technology. This complete assembly includes STN/FSTN liquid crystal panels, frames, zebra paper (conductive rubber strips), and PCB (printed circuit board). It offers advantages such as low power consumption, wide viewing angle, moderate cost, and excellent visibility in sunlight. Widely used in various instruments, industrial control systems, and consumer electronics applications.
Product Core Composition and Characteristics
STN/FSTN Liquid Crystal Panels
- STN Liquid Crystal: Super Twisted Nematic technology with liquid crystal molecules twisted 180°-270°. Capable of driving more pixels than TN screens with greater information display capacity. Available in yellow, green, and blue colors with typical displays showing blue background white characters or yellow background black characters. Ideal for text and simple graphics with lower power consumption than TFT and response speed of 150-200ms.
- FSTN Liquid Crystal: Film Compensated STN with added compensation film to eliminate chromatic dispersion, achieving black background white characters or white background black characters. Offers improved contrast and viewing angles, making it the preferred choice for high-end monochrome displays requiring superior clarity.
- Both support reflection, semi-transmission, and transmission display modes. Reflective types require no backlight for extremely low power consumption in outdoor applications, while transmission types include backlighting for low-light environments.
Frame
The frame provides structural support for the display assembly, typically manufactured from engineering plastics like ABS or metal materials. Key functions include: fixing the liquid crystal panel, PCB, and backlight components; sealing against dust and moisture; positioning tabs or installation holes for rapid assembly; and serving as a shading device to enhance display contrast.
Zebra Paper (Conductive Rubber Strip)
Zebra paper is a flexible conductive connection component that connects liquid crystal panel electrodes with the PCB. Characterized by black and white stripes where the black part contains conductive material (carbon powder or metal coating) and white parts provide insulation. Features include: accommodation of small spacing deviations between panel and PCB; easy installation without welding; vibration buffering protection; and cost-effective solution for segment displays and small dot matrix screens.
PCB (Printed Circuit Board)
The PCB serves as the core carrier for module control and driving, integrating driving ICs, controllers, resistors, and capacitors. Functions include: converting external control signals into driving voltage required by the liquid crystal panel; power management for liquid crystal, backlight, and ICs; interface provision (SPI, I²C, parallel); and circuit protection against static electricity and interference.
Core Advantages
- Low Power Consumption: Passive matrix driving with reflective modules consuming as low as micro-ampere per square centimeter, suitable for battery and solar-powered devices
- Wide Adaptability: Operating temperature range of -20℃ to 70℃ with strong anti-interference capability for harsh industrial and automotive environments
- Cost Control: Mature structure and manufacturing processes provide lower mass production costs compared to TFT and OLED
- Flexible Customization: Custom segment codes and dot matrices to meet specific character, number, and graphic display requirements
Main Applications
- Industrial Instruments and Meters: Multimeters, oscilloscopes, temperature controllers, pressure gauges
- Smart Home and Household Appliances: Air conditioners, refrigerators, washing machines, water heaters, rice cookers
- Medical Equipment: Portable blood pressure monitors, blood glucose meters, blood oxygen monitors
- Vehicle Electronics: Dashboards, tire pressure monitors, navigation key panels
- Consumer Electronics and Portable Devices: Electronic dictionaries, calculators, remote controls, fitness equipment
- Internet of Things and Industrial Control: Sensor nodes, PLC operation screens, smart meters

Frequently Asked Questions
I want the LCD display 8 digits and the outline size is 65x30x2.8mm?
No problem. Please send us your specification or drawing. If you don't have specifications, provide samples and we'll recommend suitable standard products or customize based on your requirements.
This LCD is just what we want, but it is big size, do you have any smaller size? And the display content need to be changed a little.
For segment type LCD modules requiring size modification or display content changes, new LCD glass modules with custom tooling are necessary.
This LCD display is HTN type, but I want STN type, can you make?
Yes, we can modify the display type according to your request.
I want customize a new LCD module. Can you do?
Yes, we provide custom LCD modules. Please send your drawing or provide specifications including outline size, display information, glass thickness, polarizer type, display type, connector mode, storage temperature, operating temperature, supply voltage, viewing direction, and drive conditions.
What is leading time for tooling?
Typically 15 to 25 days after drawing confirmation and tooling charge payment. Exact timing will be confirmed upon drawing approval.
Can you send us samples for checking?
Yes, sample orders are available for evaluation.
What is the Leading Time?
For standard products in stock: 1 day after payment. For mass production of special orders: 15-30 days. We'll provide updates if production completes earlier.
