1.33-inch LCD screens with a resolution of 240x240 are commonly used in smart wearable devices and other small display applications. This type of display screen can meet compact design requirements while ensuring clear information due to its small size and moderate resolution. The following is a more detailed introduction to this 1.33-inch LCD screen:
Display Features
Size and Resolution
Size: 1.33 inches diagonal length.
Resolution: 240x240 pixels, providing high enough resolution to display clear text and simple graphical interfaces
Screen Ratio
Screen Ratio: A ratio close to a square, suitable for round or square smart watches, fitness trackers and other wearable devices.
Interface Type
SPI interface: One of the common communication methods, suitable for microcontrollers (MCUs) to directly control screen content updates. It uses a serial peripheral interface for data transmission, simplifies hardware design, and is relatively easy to implement.
DC/RES/CS pins: These pins are used to control command/data selection, reset operation, and chip select signals, and are an integral part of SPI communication
Display Technology
TFT-LCD: Thin Film Transistor Liquid Crystal Display, which provides vivid colors and good contrast, suitable for good visibility when used outdoors.
IPS Panel: Some models may use IPS technology for wider viewing angles and more realistic color reproduction. However, TN panels are also very common for screens of this size because they are less expensive and have a faster response time
Physical Parameters
Active Area: The effective display area is approximately 32.4mm x 32.4mm
Dimensions: The entire module measures approximately 26mm x 29.22mm x 1.9mm, making it ideal for embedding into small devices
Backlight Control: The BLK pin can accept a PWM signal to adjust the brightness, thereby saving power and extending battery life
Application Scenarios
Due to its compact size and appropriate resolution, the 1.33-inch 240x240 LCD screen is ideal for the following applications:
Smart Wearable Devices: Personal health monitoring instruments such as smart watches and bracelets.
Portable Medical Devices: Small medical tools such as blood glucose meters and pulse oximeters.
Consumer electronics accessories: such as display screens on headphones, remote controls, etc.
Industrial automation: small HMI (human-machine interface), sensor reading display, etc.
Selection suggestions
When choosing a suitable 1.33-inch LCD screen, please consider the following aspects:
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.
Interface compatibility: Confirm whether the interface of the selected screen (such as SPI) can be seamlessly connected with the existing microcontroller or main control board.
Power consumption considerations: Especially for battery-powered products, choosing a low-power screen can extend battery life.
Cost-effectiveness: Balance the relationship between budget constraints and required functional features to find the most cost-effective solution.
If you are looking for a 1.33-inch LCD screen for a specific project, it is recommended to contact a professional supplier to obtain the latest product specifications and technical support. At the same time, considering that the specific parameters provided by different manufacturers may vary, it is very important to carefully compare the detailed information of each product. In addition, some suppliers may also provide customized services to help you better meet specific design needs.
It is worth noting that although the 1.3-inch 4K OLED micro display released by Sony is not a traditional LCD screen, it also achieves extremely high resolution within this size range and is suitable for virtual reality (VR) and augmented reality (AR) head-mounted display devices.
