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 screen with a resolution of 240x240, the active area is approximately 23.4mm x 23.4mm.
Dimensions: The size of the entire module varies depending on the specific model, but is generally compact, such as 33.8mm x 36.5mm x 1.41mm or smaller.
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 square SPI LCD panels adopt a low power design, making them ideal for small devices that rely on battery power.
Application scenarios
Due to their compact size and appropriate resolution, 1.28-inch 240x240 resolution square SPI LCD panels are ideal for the following applications:
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 square SPI LCD panel, please consider the following factors:
Performance requirements: Decide which display technology to choose (TN vs IPS) based on whether your project requires high refresh rates, full viewing angles, or other special features.
Interface compatibility: Confirm whether the SPI interface of the selected panel can be seamlessly connected with the existing microcontroller or main control board.
Power consumption considerations: Especially for battery-powered products, choosing a low-power panel can significantly extend battery life.
Cost-effectiveness: Balance the relationship between budget constraints and required functional features to find the most cost-effective solution.
