The 1.33-inch LCD module with a resolution of 240x240 is not just a simple display, but a complete solution that integrates components such as display panel, driver ICs, flexible printed circuit (FPC) and backlight unit. This type of module has been widely used in smart wearable devices, portable medical instruments and other small electronic devices due to its compact design and moderate resolution. The following is a more detailed introduction to this 1.33-inch 240x240 LCD module:
Module Features
Size and Resolution
Size: 1.33 inches diagonal length, very suitable for applications that require compact design.
Resolution: 240x240 pixels, providing enough clarity to display text and simple graphical interfaces while maintaining low cost and power consumption8
.
Screen Ratio
Screen Ratio: A ratio close to square (actually 1:1), suitable for wearable devices with round or square designs, such as smart watches or fitness trackers.
Interface Type
SPI interface: Supports data transmission via serial peripheral interface, which is a common communication method, especially suitable for resource-constrained microcontroller platforms. The SPI interface is known for its simplicity and efficient data transfer speed8
.
RGB interface: Some models may also offer an RGB interface option, allowing more direct color control for applications that require higher color accuracy9
.
MCU interface: Can be directly connected to a microcontroller unit (MCU), simplifying the system integration process and facilitating the development of embedded systems5
.
Display technology
TFT-LCD: Thin-film transistor liquid crystal display, ensuring good image quality, including vivid colors and high contrast. This is particularly important for outdoor use, as it can maintain good visibility even in strong light8
.
IPS panel: Some models may use IPS technology, providing wider viewing angles and more realistic color reproduction capabilities. Although TN panels are more common because of their lower cost and fast response time, IPS may be a better choice in cases where there is an advantage in visual experience7
.
Physical parameters
Active display area: Approximately 23.808mm x 23.808mm 9
.
Dimensions: The entire module measures approximately 26.82mm x 31.3mm x 0.745mm, making it ideal for embedding into small devices9
.
Backlight control: The BLK pin can accept a PWM signal to adjust the brightness, thereby saving energy and extending battery life1
.
Power consumption characteristics
Low power consumption: For example, the LS013B7DH06 model in the Sharp Memory LCD series consumes much less power than a standard LCD panel of the same size, only about 1/130 times of the latter, which is particularly important for small devices that rely on battery power3
.
Application scenarios
Due to its compact size and appropriate resolution, the 1.33-inch 240x240 LCD module is 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.3
.
Selection Tips
When choosing a specific 1.33-inch 240x240 LCD module, consider the following factors:
Performance requirements: Decide which display technology (TN vs IPS) to choose based on whether your project requires high refresh rates, full viewing angles, or other special features.
Interface compatibility: Confirm whether the interface of the selected module (such as SPI or RGB) can be seamlessly connected to 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.
If you are looking for a 1.33-inch 240x240 LCD module 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 there are more diverse options on the market, such as the 1.3-inch 4K OLED microdisplay released by Sony, this type of high-end product is mainly aimed at virtual reality (VR) and augmented reality (AR) head-mounted display devices, and the target market is concentrated on professional applications. Compared with the conventional 1.33-inch 240x240 LCD module, the price and technical threshold are higher. However, for most ordinary consumers and developers, the 1.33-inch 240x240 LCD module can already meet the needs of daily use.
