The GT915L is a capacitive touch screen controller with the following main functions:
1. High-Precision Touch Sensing: It uses advanced capacitive sensing technology to accurately detect touch points on the screen, with high resolution and sensitivity, enabling precise operation such as single touch and multi-touch.
2. Multi-Touch Support: Can recognize multiple touch points simultaneously, usually supporting up to 5-finger or even more advanced multi-touch gestures, facilitating operations like pinch-to-zoom and swipe.
3. Fast Response: Has a fast response speed, which can quickly process touch events and provide a smooth touch experience, reducing lag and ensuring real-time interaction.
4. Low Power Consumption: Designed with power-saving features, operating in a low-power mode to reduce overall power consumption and is suitable for battery-powered devices such as mobile phones and tablets.
5. Wide Operating Voltage Range: Usually works within a wide voltage range, such as 2.5V to 3.6V, providing good compatibility with different power supply systems.
6. I²C Interface: Communicates with the host processor through the I²C bus interface, which is easy to integrate into the system and has good scalability and compatibility.
7. Built-in Self-Calibration: Equipped with a self-calibration function that can automatically adjust and optimize touch sensing parameters to adapt to different environmental conditions and ensure stable touch performance.
8. Noise Immunity: Has strong anti-interference ability, can effectively suppress external electromagnetic interference and noise, and improve the stability and reliability of touch detection.
