Module Features
Dimensions and Resolution
Dimensions: 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
Square Design: The screen itself is square, which makes it very suitable for wearable devices or small portable devices with square 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 (select 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 also 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.
Other interfaces: Some models may also provide RGB interface options, allowing more direct color control, suitable for application scenarios that require higher color accuracy.
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 LCD modules adopt a low-power 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 square 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 square LCD module, please consider the following factors:
Performance requirements: Decide which display technology (TN vs IPS) to choose 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 that require high display quality.
Interface compatibility: Confirm whether the interface (such as SPI or RGB) 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 battery life.
Cost-effectiveness: Balance the relationship between budget constraints and required functional features to find the most cost-effective solution.
