Basic parameters
Size: The diagonal size is 1.44 inches, and the effective display area is generally about 25.5mm × 26.5mm.
Resolution: It is 128×128 pixels. The pixel arrangement is mostly RGB vertical stripes, and the pixel pitch varies by model. For some products, it is 0.1992mm × 0.207mm.
Display mode: Transmissive type. Usually, it is the standard white mode, meaning the screen shows white when there is no signal.
Color performance: Most products support 262K color display and can present relatively rich image effects.
Viewing angle: Common viewing angles include 6:00 angle. Some products with IPS panel technology can provide a wider viewing angle, such as 80 degrees on the left/right/upper/down.
Brightness: The brightness of different products varies, generally ranging from 200cd/m² to 500cd/m².
Interface and Driver
Interface Type: Common types include MCU interface and SPI interface, which facilitate connection with microcontrollers and enable data transmission and display control.
Driver Chip: ST7735S is often used as the driver chip. This chip has high integration and can provide high-speed interfaces and various display functions, such as color inversion, partial display modes, etc.
Operating Conditions
Operating Temperature: Generally -20°C to 70°C, capable of meeting the usage requirements of most conventional environments.
Storage Temperature: Usually -30°C to 80°C, ensuring reliability in different storage environments.
Application Domains
Smart Wearables: Such as children's smart watches, fitness trackers, etc., used to display time, steps, heart rate, etc.
Industrial Control: As a small display interface, it shows machine working status, parameter settings, etc.
Consumer Electronics: Can be applied to portable audio players, electronic dictionaries, etc., to display relevant information.
