Product Core Information

It is a monochrome STN/FSTN type graphic dot matrix liquid crystal module with 240 pixels horizontally and 128 pixels vertically. It can clearly display text, numbers, icons, and simple waveforms. 1/128 Duty refers to the dynamic driving duty cycle, meaning that 128 rows of pixels are divided into 128 groups and scanned alternately for driving. Combined with the common 1/12 Bias bias design, it can effectively reduce the number of driving chips and power consumption, while ensuring display uniformity and stability. The 5V DC/DC power supply design is a significant feature. The module is equipped with a DC/DC conversion circuit (such as a charge pump) that can generate positive and negative voltages required for driving the liquid crystal from a 5V input voltage, without the need for an additional negative voltage power supply, simplifying peripheral circuits and enhancing system integration convenience, and also making the module suitable for most 5V-powered embedded systems and single-chip microcomputer application scenarios.

In terms of core configuration, these modules often come with mainstream controllers such as T6963C, ST7565, and RA8803, supporting 8-bit parallel or SPI, I2C serial interfaces, facilitating connection with MCUs; some models are equipped with ASCII character libraries or Chinese character libraries, allowing direct display of characters and also enabling customization of graphics and font patterns through display RAM. The display effect is mostly in single-color negative display / positive display modes, with white background and black text or vice versa, and is accompanied by a white LED side-emitting backlight, with adjustable brightness, meeting the visual requirements in different lighting environments. Mechanical specifications: The standard module has an approximate size of 144.0mm × 104.0mm × 13-14mm, a visible area of approximately 114.0mm × 64.0mm, a dot size of 0.4 × 0.4mm, a dot pitch of 0.45 × 0.45mm, and the working temperature typically covers a wide temperature range of -20℃ to 70℃, suitable for industrial and outdoor complex environments.

Core Applications

Industrial Instrumentation: This is its most core application field. In devices such as multimeters, oscilloscopes, signal generators, temperature/pressure transmitters, etc., it can stably display measurement data, waveform curves, parameter setting menus and alarm prompts. The uniform display of 1/128 Duty and the stable power supply of 5V DC/DC can ensure the equipment to operate reliably for a long time in factories, outdoors, etc.

Medical and Health Equipment: Suitable for portable or desktop medical devices such as blood glucose meters, blood pressure monitors, electrocardiogram monitors, ultrasound diagnostic devices, etc., it can clearly present patients' physiological data, waveform diagrams, operation instructions, etc. The wide temperature characteristics and low power consumption design are in line with the dual requirements of stability and battery life of medical devices.

Vehicle and Transportation Electronics: In devices such as vehicle diagnostic instruments, navigation devices (simple route display), tire pressure monitors, vehicle air conditioning control panels, etc., this module can stably display vehicle status parameters, fault codes, operation interfaces, etc. in the environment of temperature fluctuations inside the vehicle. The 5V power supply is also compatible with the common voltage standards of vehicle electronic systems.

Smart Home Appliances and Security Equipment: Such as control panels for washing machines, refrigerators, ovens, etc., they can display running programs, temperatures, times, etc. In the local display terminals of access control hosts, alarm controllers, monitoring devices, etc., they can present user information, alarm status, device parameters, etc. The single-color display and low power consumption characteristics meet the cost and energy consumption control requirements of home appliances and security equipment.

Portable Terminals and Embedded Devices: Used for handheld data collectors, barcode scanners, POS machines, lottery terminals, etc., they can display transaction data, collected information, operation prompts, etc. The built-in DC/DC circuit reduces the size of the power module, and the low power consumption design of 1/128 Duty helps to extend the usage time of battery-powered equipment.

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

of the LCD display, display information( Glass thickness, Polarizer, Display Type, Connector mode,
Storage Temp. Operating Temp. Supply Voltage, Viewing direction, drive condition), we can customize for you.

5. What is leading time for tooling?
Answer: General speaking, it will cost 15 to 25 days after drawing paper confirmation and tooling charge payment,

we can report you the exact time when you confirm the drawing paper.

6. Can you send us samples for checking?
Answer: Yes,. Samples order is available.

7. What is the Leading Time?
Answer: If we have stock for the standard ones, the leading time is one day after payment. If it is the mass production for

special ones, the leading time is about 15-30 days. suppose we can finish earlier, we will report the information in advanced.
