Monochrome LCD Display STN/FSTN Module with 16 Characters X 2 Lines Reflective Polarizer and Low Power Consumption

Monochrome LCD Display STN / FSTN LCD, Bezel, Zebra And PCB

General Specification:

The STN/FSTN monochrome liquid crystal display is a passive matrix display module based on the super-twisted nematic technology. Its core consists of STN/FSTN liquid crystal panels, frames, zebra paper (conductive rubber strips), and PCB (printed circuit board), etc. It has advantages such as low power consumption, wide viewing angle, moderate cost, and good visibility in sunlight. It is widely used in various instruments and meters, industrial control, and consumer electronics scenarios. The following will explain it from the product composition, core characteristics, and application scenarios.

l. Product Core Composition and Characteristics

1. STN/FSTN Liquid Crystal Panels

STN Liquid Crystal: Full name is Super Twisted Nematic (STN), the liquid crystal molecules have a twisting angle of 180° - 270°. Compared with TN screens, it can drive more pixels and has a larger amount of display information. Common colors include yellow, green, and blue. The typical display is blue background white characters or yellow background black characters. It is suitable for displaying text and simple graphics. The power consumption is lower than TFT, and the response speed is relatively slow (about 150-200ms).
FSTN Liquid Crystal: Full name is Film Compensated STN (FSTN), which adds a compensation film to the STN basis, eliminating chromatic dispersion and achieving black background white characters or white background black characters. The contrast and viewing angle are further improved. It is the mainstream choice for high-end monochrome displays and is mostly used in devices with higher requirements for display clarity.
Both support reflection, semi-transmission, and transmission display modes. The reflective type does not require a backlight, has extremely low power consumption, and is suitable for outdoor and low-power scenarios; the transmission type requires a backlight and is suitable for weak light environments.

2. Frame

The frame is the structural supporting component of the display. It is usually made of engineering plastics such as ABS or metal materials, and its functions include: fixing the liquid crystal panel, PCB, and backlight components, preventing internal structural damage from external force impact; sealing and preventing dust and moisture, protecting the liquid crystal and circuitry from environmental erosion; some have positioning tabs or installation holes, facilitating the rapid assembly of the module into terminal equipment and serving as a shading device to enhance display contrast.

3. Zebra Paper (Conductive Rubber Strip)

Zebra paper is a flexible conductive connection component that connects the liquid crystal panel electrodes with the PCB. The surface has black and white stripes, with the black part being the conductive layer (carbon powder or metal coating), and the white part being the insulating layer. It has the following characteristics: it can adapt to the small spacing deviation between the panel and the PCB, is easy to install, achieves reliable conductivity through heat pressing or pressure contact without welding, is suitable for mass production; it has certain elasticity and can buffer vibration to protect the connection part, and is commonly used for signal transmission in segment display screens and small-sized dot matrix screens, with a cost lower than FPC soft boards.

4. PCB (Printed Circuit Board)

PCB is the core carrier of the module's control and driving. It integrates driving ICs, controllers, resistors, capacitors, etc., and functions include: carrying the driving circuit to convert external control signals into the driving voltage required by the liquid crystal panel, controlling pixel switching and display content; providing power management to supply power to the liquid crystal, backlight, and ICs, ensuring stable operation with low power consumption; providing interfaces (such as SPI, I²C, parallel interfaces) to facilitate communication with the host or single-chip microcomputer, supporting real-time refreshing of display data, and protecting the circuit from static electricity and interference.

II. Core Advantages

Low Power Consumption: Passive matrix driving, reflective modules do not require backlighting, and the power consumption can be as low as micro-ampere per square centimeter, suitable for battery and solar power supply devices.
Wide Adaptability: Supports -20℃ - 70℃ or even wider operating temperatures, strong anti-interference ability, suitable for harsh environments such as industrial and vehicle use.
Cost Control: Mature structure and process, mass production cost is lower than TFT and OLED, suitable for cost-sensitive mid-to-low-end batch applications.
Flexible Customization: Can be customized in terms of segment codes, dot matrices, etc., to meet the display requirements for different characters, numbers, and simple graphics.

III. Main Applications

Industrial Instruments and Meters: Multimeters, oscilloscopes, temperature controllers, pressure gauges, etc., used for displaying measurement data and status parameters. FSTN's black-and-white display is convenient for quick reading, and the wide temperature characteristics are suitable for workshops and outdoor environments.
Smart Home and Household Appliances: Control panels for air conditioners, refrigerators, washing machines, displaying temperature, operating modes, time, etc.; operation interfaces for water heaters, rice cookers, with low power consumption suitable for long-term standby requirements.
Medical Equipment: Portable medical devices such as blood pressure monitors, blood glucose meters, blood oxygen monitors, displaying test results, low power consumption extends battery life, high contrast facilitates reading by elderly users and medical staff.
Vehicle Electronics: Vehicle dashboards (fuel level, speed, mileage display), tire pressure monitors, vehicle navigation key panels, wide temperature and anti-vibration characteristics are suitable for vehicle driving environments.
Consumer Electronics and Portable Devices: Electronic dictionaries, calculators, remote controls, treadmills/weight scales, displaying text, numbers, and sports data, low cost and low power consumption meet batch production requirements.
Internet of Things and Industrial Control: Sensor nodes, PLC operation screens, smart meters, reflective design is suitable for outdoor installation, low power consumption is suitable for battery or solar power supply, stable data transmission.

FAQ:

1. I want the LCD display 8 digits and the outline size is 65x30x2.8mm………?

Answer: No problem. Firstly, please kindly send us your specification/ drawing paper

If you have not the specification, you can also provide your samples; we will recommend the suitable one

if it is standard products. Or we can customize for you based on your own requirement.

2.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.
Answer: For the segment type LCD module, if you need modify the outline size or display content,

a new LCD glass module is need. We have to open new tooling for you.

3. This LCD display is HTN type, but I want STN type,can you make?
Answer: That’s all right . we can change for you as per you request.

4. I want customize a new LCD module. Can you do?
Answer: Yes, we can. Please send your drawing paper. If you have not, please advise me the outline size
