The following is the detailed product introduction and usage instructions:
Product Introduction
Core basic configuration: This display module has a diagonal size of 2.1 inches, with a display area diameter of 53.28 millimeters, and the overall module size is only 56.18×59.71×2.3 millimeters. Its compact and lightweight design makes it easy to integrate into various small devices. It uses a resolution of 480×480 and a typical brightness of 300 nits, which can present clear and vivid images. The typical contrast ratio of 900:1 makes the image's light and dark gradations more distinct. It has 262K colors and an NTSC color gamut of 70%, which can reproduce rich and realistic colors. Additionally, it adopts IPS display technology, with a viewing angle of 80 degrees in all four directions, ensuring that the picture quality does not deteriorate from different viewing angles.
Core control and interface advantages: Its core is equipped with the ST7701S chip, which combines the functions of a controller and a driver. It not only runs stably but also enables the module to support 18-bit RGB interfaces and 3-wire SPI interfaces simultaneously. The 18-bit RGB interface ensures efficient transmission of color data, making color display more detailed, while the SPI interface simplifies the connection with various master control chips and enhances compatibility with different devices. Moreover, the module's power supply voltage range is wide, ranging from 2.5V to 4.8V, and it can work normally within the typical working voltage of 2.8V, which is suitable for the power supply systems of most devices.
Practical additional features: This module has good environmental adaptability. Its operating temperature range is from -20ºC to +70ºC, and the storage temperature range is from -30ºC to +80ºC, capable of coping with temperature changes in various scenarios such as home and industry. It also supports custom resistive touch screens or projected capacitive touch screens, allowing it to be upgraded to an interactive display module as needed, and the backlight is composed of 4 LEDs, with a lifespan of up to 40,000 hours, meeting the long-term usage requirements of most devices.
Product application
Consumer electronics sector: In small wearable devices, it can serve as the display screen for smart bracelets and mini smart watches, used to show time, heart rate, exercise data, etc. Its circular appearance is highly compatible with the design style of these products. In smart home small appliances, such as coffee machines and microwave ovens, it can display working modes, remaining time, temperature and other parameters, making it convenient for users to visually check the operating status of the equipment. Additionally, it can also be used in small portable audio-visual devices to present simple pictures and operation menus.
Industrial and Internet of Things sector: In various small analyzers and detectors in industrial scenarios, this module can display key information such as detection data and equipment operation status alerts, helping staff quickly read the data. On the front terminals of access control systems and monitoring devices, it can display card swipe results, whether the equipment is operating normally, etc. In IoT devices such as garden irrigation controllers, it can also serve as a human-computer interaction interface to display irrigation time, water volume, etc. settings parameters.
Other special scenarios: In some customized small medical auxiliary devices, such as portable blood glucose testers and blood oxygen meters, it can clearly display detection values, facilitating patients and medical staff to view them. It is also applicable to small security alarm devices, etc., by displaying alarm types, device addresses, etc., to enhance the convenience of device use.
