1.3-inch Resolution 240x240 Circular Interface SPI View Direction Full/IPS LCD Display Guide
For 1.3-inch, 240x240 pixel resolution circular LCD displays, especially those with SPI interface and IPS panel technology, here are the key information and usage guidelines you need to know. Such displays are widely used in smart watches, fitness trackers, medical devices, and other small portable electronic products.
1. Product Overview
Size: 1.3-inch diagonal
Resolution: 240x240 pixels (QVGA)
Shape: Circular
Interface Type: SPI (Serial Peripheral Interface)
Display Technology: IPS (In-Plane Switching) or TN (Twisted Nematic), where IPS provides a wider viewing angle and better color performance
Viewing Angle: Full View, which means that the image quality is maintained when viewed from different angles
2. Main Features
High resolution and small size: Provides clear and delicate picture display in a limited space.
Circular design: Suitable for application scenarios with circular dials or other non-rectangular interfaces.
Wide viewing angle: IPS technology ensures clear and color-free images even from the side.
Low power consumption: Designed for battery-powered devices, it helps extend battery life.
Easy integration: The SPI interface can be easily connected to a microcontroller (MCU) or other embedded system.
3. Hardware connection
SPI interface pin definition:
MOSI (Master Out Slave In): data input
MISO (Master In Slave Out): data output (usually not used for LCD)
SCLK (Serial Clock): clock signal
CS (Chip Select): chip select signal
DC (Data/Command): data/command selection
RST (Reset): reset signal
BL (Backlight Control): backlight control (if applicable)
Power requirements:
VCC: usually 3.3V or 5V, depending on the model
GND: ground
4. Drive and programming
Initialization settings:
Before you start displaying content, the LCD must be properly initialized. This usually includes sending a series of configuration instructions to set parameters such as display mode and brightness.
Graphics library support: Many development boards and microcontroller platforms (such as Arduino, ESP32, STM32, etc.) provide ready-made graphics libraries, such as Adafruit GFX Library or u8g2lib, which simplify drawing operations.
5. Application Examples
Smart watches: The round screen fits the dial design perfectly and provides enough space to display time and notification information.
Fitness trackers: Used to display sports data, such as steps, heart rate monitoring results, etc.
Medical equipment: Small handheld devices such as blood glucose meters and blood pressure monitors require a compact but clear user interface.
Consumer electronics: For example, music players, remote controls, etc., require a small and fully functional display.
6. Purchase suggestions
Brand and supplier: Choose a display from a well-known brand to ensure quality and after-sales service. You can buy it through online platforms such as Alibaba, Digi-Key, Mouser, etc.
Documentation and support: Confirm the detailed data sheet and technical support resources provided by the supplier, which is crucial for smooth integration.
Price and bulk purchase: Compare prices from different suppliers and consider the possibility of bulk purchase to get a better price.
7. Maintenance and Care
Avoid scratches: Handle the screen surface carefully to prevent scratches caused by sharp objects.
Cleaning method: Wipe gently with a soft, slightly damp cloth, and avoid using cleaners containing alcohol or other corrosive chemicals.
Storage conditions: When not in use for a long time, please store in a dry, cool place away from direct sunlight.
With the above information, you can better understand and utilize the 1.3-inch 240x240 pixel circular SPI interface IPS LCD display. If you have any further questions or need specific advice, please feel free to consult a professional or contact the relevant manufacturer.
