Product Introduction
Display Performance
Resolution and PPI: The screen resolution is 480×480, and at a size of 2.1 inches, the PPI is as high as 274, with a pixel pitch of only 0.111×0.111mm, allowing for clear display of minute details.
Brightness and contrast: Utilizing IPS full-view technology, the screen brightness reaches 820cd/m², with a contrast ratio of 800:1, maintaining clarity even in outdoor strong light.
Color gamut and viewing angle: Supports 16.7M color display and 178° full viewing angle, ensuring good color consistency when viewed from different angles.
Interfaces and Drivers
Interface types: Supports multiple interfaces such as SPI, RGB, MIPI, etc., and can be compatible with ARM Cortex-M series microcontrollers and processors like RK3566, with strong compatibility.
Driver IC: Uses the ST7701S driver chip, supporting 18-bit RGB data transmission and PWM dimming, achieving millisecond-level response speed.
Touch technology: Supports capacitive touch, with a response time of less than 10ms, a false touch rate of less than 0.1%, and smooth and precise operation.
Environmental Adaptability
Operating temperature: Supports wide temperature operation from -20°C to 70°C, and can work stably in different environmental temperatures.
Protection level: Obtains IP65 protection certification, possessing certain dust and water resistance capabilities, and can adapt to harsher usage environments.
Backlight design: Uses 4 white LED backlights, with a current of 80mA and a voltage of 2.8-3.3V, with a backlight lifespan of up to 50,000 hours.
Main Applications
Smart home: It can be used for smart temperature control knobs, which can display and adjust temperature, humidity, and other parameters in real time, helping users precisely control the indoor environment and reduce energy consumption. It can also be applied to smart door lock knobs, supporting functions such as face recognition and fingerprint unlocking, improving the security and intelligence level of the door lock.
Smart wearables: For example, smart watches can clearly display health data such as heart rate and blood oxygen. The high PPI makes the font edges sharp, enhancing the user's reading experience. Smart rings can also be embedded with this screen to achieve real-time display of exercise data and message alerts.
Medical equipment: It can be used in portable monitors, which can display physiological parameters such as ECG and SpO₂ in real time. The high contrast design helps medical staff accurately identify waveforms and reduces the error rate. When applied to endoscope knobs, the high-brightness screen enables doctors to operate the equipment clearly in low-light environments.
Automotive electronics: It can be used as an in-car knob screen, supporting touch control adjustment of functions such as air conditioning and seats. The full-lamination design enables rapid operation feedback. It can also be used in HUD knob controllers to achieve rapid switching of navigation information and driving modes.
Industrial control: It can be applied to intelligent knob switches, supporting multi-level menu switching and parameter adjustment, improving equipment operation efficiency. When applied to AGV scheduling terminals, it can display real-time task allocation and path planning information, improving scheduling efficiency.
