The 1.28-inch 240x240 resolution circular SPI interface full-color/IPS LCD panel is a product designed for applications that require a compact, high-resolution display solution. Here are some details about this panel:
Technical Specifications
Size: A circular screen with a diameter of 1.28 inches (about 32.5 mm), suitable for wearable devices, smart home devices or small embedded systems.
Resolution: 240x240 pixels, providing clear text and image display, especially suitable for menu navigation, icons and small-scale graphic content.
Interface Type: SPI (Serial Peripheral Interface) interface, which is a commonly used serial communication protocol for data transmission between microcontrollers and peripheral devices.
Display Technology: IPS (In-Plane Switching) screen technology ensures a wide viewing angle and better color reproduction, and the contrast and brightness are also excellent.
Color Depth: If it is a "full color" screen, it usually supports 16-bit or 24-bit color depth, which means that it can display thousands of colors, thus achieving rich color performance.
Application Areas
This type of panel is widely used in:
Smart watches and other wearable devices
Small medical instruments
Internet of Things (IoT) devices
Home automation control panels
Portable payment terminals such as mobile POS machines
Development considerations
Driver chip: Choosing the right LCD driver chip is key because it directly affects the screen refresh rate, power consumption, and image quality.
Graphics library: To simplify the development process, you can use existing graphics libraries (such as LVGL, uGFX, etc.), which provide functions such as drawing lines, rectangles, texts, and even support more complex GUI elements.
Power management: Considering the issues of portability and battery life, an effective power management system is essential to extend the working time of the device.
Touch function (if applicable): Some of these panels may also be equipped with a capacitive touch screen, which will increase the possibility of user interaction.
