Product Core Features
This color circular display module is specifically designed for
small portable smart devices. With a diagonal size of 1.22 inches
and resolution of 240*204, it utilizes IPS (In-Plane Switching)
wide-angle technology to deliver clear viewing angles exceeding 80°
in all directions without color distortion or brightness
degradation.
The display is driven by ST7789V/ST7789H2 IC with a standard 4-wire
SPI high-speed interface (10-pin design). This simple communication
protocol requires minimal wiring and offers perfect compatibility
with mainstream embedded platforms including Arduino, STM32, and
Raspberry Pi, supported by comprehensive driver libraries and
sample codes for rapid development.
Display capabilities include 262K true colors, brightness of
approximately 300 cd/m², and contrast ratio of 700:1, ensuring
vivid and clear images in most indoor and outdoor scenarios. The
ultra-thin module design (typically under 2.6mm, with ultra-thin
versions at 1.35mm) and lightweight construction facilitate easy
integration into compact structures.
Operating temperature ranges from -10℃ to 60℃, with
industrial-grade versions extending to -20℃ to 70℃, suitable for
both consumer and industrial applications. Optional capacitive
touch functionality further expands interaction possibilities.
Technical Advantages
- Lower cost and superior burn-in resistance compared to OLED
displays of similar size
- IPS full-viewing angle technology outperforms ordinary TN screens
in color stability and viewing angles
- SPI interface optimizes speed while conserving hardware resources
for microcontroller systems
Typical Applications
- Smart wearable devices: Smart watches, fitness trackers, and sports
accessories displaying time, heart rate, steps, and battery levels
with traditional circular aesthetics
- Maker and open-source hardware: Color status panels for Raspberry
Pi and Arduino projects showing sensor data, graphical UI, and
debugging information
- Portable instruments and medical devices: Handheld blood pressure
monitors, pulse oximeters, and environmental detectors with clear
multi-angle readability
- Smart home and IoT terminals: Circular smart switches, thermostats,
and gateway panels enhancing product appearance and user
interaction
- Vehicle and industrial displays: Tire pressure monitors, industrial
meters, and PLC auxiliary displays suitable for environments with
vibrations and temperature fluctuations
- Toys and consumer electronics: Small robots, Bluetooth speakers,
and headphones with status and battery level displays
Frequently Asked Questions
I want the LCD display 8 digits and the outline size is
65x30x2.8mm. Can you provide this?
Yes, we can accommodate your requirements. Please provide your
specifications or drawing. If you don't have specifications, you
can send samples and we'll recommend suitable options from our
standard products or customize according to your needs.
This LCD is what we want, but the size is too big. Do you have
smaller sizes? The display content also needs minor changes.
For segment-type LCD modules requiring size modifications or
display content changes, we need to create a new LCD glass module,
which involves opening new tooling specifically for your project.
This LCD display is HTN type, but I want STN type. Can you make
this change?
Absolutely. We can modify the display type to STN according to your
requirements.
I want to customize a new LCD module. Can you do this?
Yes, we specialize in custom LCD modules. Please provide your
drawing or specifications including outline size, display
information (glass thickness, polarizer, display type, connector
mode, storage temperature, operating temperature, supply voltage,
viewing direction, drive conditions).
What is the lead time for tooling?
Typically, tooling requires 15 to 25 days after drawing
confirmation and tooling charge payment. We will provide exact
timelines once your drawing is confirmed.
Can you send samples for evaluation?
Yes, sample orders are available for your testing and evaluation
purposes.
What is the production lead time?
For standard products in stock, lead time is one day after payment.
For mass production of custom orders, lead time is approximately
15-30 days. We will notify you in advance if we can complete your
order sooner.
