This IPS circular TFT liquid crystal display is a display module suitable for small smart devices and embedded projects. With its compact size, flexible display characteristics, and simple interface, it has high adaptability in consumer electronics and industrial control scenarios.
Product Core Characteristics
Outstanding Display Performance
Features a small-sized screen around 0.90 inches with 128x128 resolution using TFT thin film transistor technology, capable of presenting 262K colors with rich and detailed images. Clearly displays text, simple graphics, and animations. The IPS panel provides full-angle viewing with no significant viewing angle differences. The circular appearance distinguishes it from traditional square screens, suitable for devices with special aesthetic requirements.
Flexible Interface & Power Efficiency
Utilizes a 4-wire SPI interface requiring minimal pins for data transmission, significantly reducing hardware complexity. Compatible with microcontrollers like Arduino and STM32. Operating temperature range of -20°C to 70°C adapts to most daily and industrial environments. Most modules operate at 3.3V with some integrating level conversion circuits for 5V microcontroller compatibility. Features backlight control pin for PWM brightness adjustment and energy-saving control.
Advanced Driver Chip Technology
Powered by ST7735P3 driver chip with integrated RGB digital-to-analog converter and GPIO interface. Supports hardware-accelerated graphic drawing for fast point, line, rectangle, and text operations. Includes gamma correction, window setting, and sleep functions with extremely low power consumption in sleep mode, ideal for battery-powered portable devices.
