A 1.33-inch 240x240 circular interface SPI full/IPS LCD panel has the following features:
Size: The screen is 1.33 inches diagonally, which is a relatively small display and suitable for compact devices.
Resolution: Both horizontal and vertical pixel counts are 240, which provides a relatively clear display for this size.
Shape: Circular interface, which is very popular in wearable devices such as smart watches and fitness trackers.
Interface: SPI (Serial Peripheral Interface), which is a simple serial communication protocol suitable for short-distance data transmission. It usually contains four lines: a clock line (SCK), a master output slave input line (MOSI), a master input slave output line (MISO), and a select line (SS). For LCD screens, only SCK, MOSI, and SS lines are usually used, because data is usually sent to the display in one direction.
Viewing direction: When mentioning "full", this usually refers to the wide viewing angle characteristics, which means that the screen content can maintain good visibility no matter from which angle it is viewed, and the color and contrast will not change significantly.
Type: IPS (In-Plane Switching) panel, which provides better color reproduction, higher contrast, and wider viewing angles, which is good for users to view the screen at different angles.
