Technical Details
This high-resolution circular display features 480×480 resolution with high pixel density for detailed imagery. Utilizing IPS wide-angle technology, it maintains consistent colors and brightness from all viewing angles while supporting 262K full-color display. Equipped with white LED backlighting rated at 350-400 nits for excellent outdoor visibility.
The ST7701S driver IC supports a composite interface scheme: 3-wire SPI (SCK/CS/SDA) handles initialization, brightness adjustment, and display direction control, while the 18-bit RGB parallel interface manages high-speed image data transmission. This balanced approach ensures compatibility with popular embedded platforms including STM32, ESP32, and Raspberry Pi, with comprehensive driver libraries and sample code available.
Electrical specifications include 3.3V operating voltage, -20℃ to 70℃ operating temperature range, and -30℃ to 80℃ storage temperature range, suitable for both industrial and consumer applications. The compact module design maintains thickness under 2.5mm with FPC flexible ribbon cable connection, with optional capacitive touch panel (G+FF process) and custom cover glass available.
Typical Applications
• Smart Wearable Devices: Circular smart watches and fitness trackers displaying dials, health data, and notifications
• Portable Instruments: Handheld medical testing devices, weather stations, and tire pressure monitors with circular chart displays
• Industrial Control & IoT: Small PLCs, sensor gateways, and smart home panels with multi-directional viewing capability
• Maker Projects: Arduino and ESP32 prototypes displaying environmental data and system status
• Consumer Electronics: Status display panels for smart speakers, in-car displays, and VR/AR accessories
Frequently Asked Questions
I want the LCD display 8 digits and the outline size is 65x30x2.8mm?
Yes, we can accommodate custom specifications. Please provide your detailed specifications or drawing. If you don't have specifications, you can send 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 modifications or display content changes, we need to create new LCD glass modules with custom tooling.
This LCD display is HTN type, but I want STN type, can you make?
Yes, we can modify the display type according to your specific requirements.
I want customize a new LCD module. Can you do?
Absolutely. Please provide your drawing or specify the outline size, display information (glass thickness, polarizer, display type, connector mode, storage temperature, operating temperature, supply voltage, viewing direction, drive conditions).
What is leading time for tooling?
Typically 15 to 25 days after drawing confirmation and tooling charge payment. We'll provide exact timelines upon drawing approval.
Can you send us samples for checking?
Yes, sample orders are available for evaluation.
What is the Leading Time?
Standard products in stock ship within one day after payment. Mass production for custom orders typically takes 15-30 days. We'll notify you if we can complete orders earlier than expected.
Your message must be between 20-3,000 characters!
