This type of module not only provides a clear information display platform, but also has the characteristics of low power consumption and easy integration, which is very suitable for battery-powered applications. Here is a more detailed introduction to this 1.28-inch 240x240 resolution circular SPI LCD module:
Module Features
Size and Resolution
Size: 1.28 inches diagonal length, suitable for applications that require compact design.
Resolution: 240x240 pixels, providing clearer text and image display effects, suitable for applications that require fine display.
Screen Shape
Circular Design: The screen itself is circular, which makes it very suitable for wearable devices or small portable devices with circular design, providing better visual experience and stylish appearance.
Display Technology
TFT-LCD: Thin Film Transistor Liquid Crystal Display, ensuring good image quality, including bright colors and high contrast.
IPS panel (some models): uses IPS (In-Plane Switching) technology to provide wider viewing angles and more realistic color reproduction. IPS panels have better visual effects than TN (Twisted Nematic) panels, especially for users who need to view the screen from different angles. IPS technology improves color accuracy and consistency, making the image look more natural.
Interface type
SPI interface: Supports data transmission via the serial peripheral interface (SPI), which is a common communication method, especially suitable for resource-constrained microcontroller platforms. The SPI interface is known for its simplicity and efficient data transmission speed, which is very suitable for embedded system development.
Physical parameters
Active display area: For a circular screen with a resolution of 240x240, the active area is approximately 23.4mm in diameter.
Dimensions: The size of the entire module varies depending on the specific model, but is generally compact, such as about 36mm in diameter and 1.41mm thick or less.
Backlight control: The BLK pin can accept a PWM signal to adjust the brightness, thereby saving energy and extending battery life.
Power consumption characteristics
Low power consumption: Many 1.28-inch 240x240 resolution circular SPI LCD modules adopt a low power consumption design, making them ideal for small devices that rely on battery power.
Application scenarios
Due to its compact size and appropriate resolution, the 1.28-inch 240x240 resolution circular SPI LCD module is very suitable for the following fields:
Smart wearable devices: such as personal health monitoring instruments such as smart watches and bracelets.
Portable medical devices: such as small medical tools such as blood glucose meters and pulse oximeters.
Consumer electronics accessories: such as displays on headphones, remote controls, etc.
Industrial automation: small HMI (human-machine interface), sensor reading display, etc.
Selection suggestions
When choosing a specific 1.28-inch 240x240 resolution circular SPI LCD module, please consider the following factors:
Performance requirements: Decide which display technology to choose (TN vs IPS) based on whether your project requires high refresh rate, full viewing angle or other special features. IPS panels have advantages in visual experience and are suitable for applications with high display quality requirements.
Interface compatibility: Confirm whether the SPI interface of the selected module can be seamlessly connected with the existing microcontroller or main control board.
Power consumption considerations: Especially for battery-powered products, choosing a low-power module can significantly extend the battery life.
Cost-effectiveness: Balance the relationship between budget constraints and required functional features to find the most cost-effective solution.
