Both GT911 and GT928 belong to the GT9 family of non-single-layer multi-touch chips, and they have some differences in functionality and performance:
< br >
Touch count: The GT911 supports up to 5 touch points while the GT928 supports up to 10 touch points. This means that the GT928 can implement more finger touch operations and provide a richer interactive experience.
Drive and sensing channels: The drive and sensing channels may differ between the GT911 and the GT928. These channels are used to receive and process touch signals, and different channel designs can affect the sensitivity and accuracy of touch.
Compatibility: The GT911 and GT928 may also differ in terms of compatibility. They may have different compatibility with different operating systems, chipsets, or device interfaces. You need to select them based on your application scenario.
It should be noted that these are just some of the common differences between the GT911 and the GT928, and specific differences may also involve other aspects, such as power consumption, size, interface, and so on. When choosing to use, it is recommended to refer to the relevant technical documentation or consult the supplier for more detailed information.
The GT911 and GT928 are both touch chips used in large-screen navigation systems, and the main differences between them are as follows:
1. Accuracy and sensitivity: The GT928 is superior in terms of accuracy and sensitivity, providing more accurate and fast touch response.
2. Multi-touch support: GT928 supports multi-touch, which can detect and process multiple touch points at the same time. The GT911 only supports single touch.
3. Power supply voltage range: The GT928 is suitable for a wider range of power supply voltage, which can meet the needs of more different types of equipment. 4. Chip performance: The GT928 chip has stronger performance and can handle more complex computing tasks and data processing, making the operation of the large-screen navigation system more smooth and stable.
It should be noted that the specific difference may also be affected by the personalized customization and configuration choices of various manufacturers, so it is necessary to consider comprehensively when purchasing equipment according to actual needs.
The GT911 and GT928 are both touch-control chips, but there are some differences.
1. Performance: The GT928 has higher performance than the GT911. It uses more advanced technologies and algorithms to provide faster touch response and more accurate touch positioning.
2. Features: The GT928 is relatively comprehensive in terms of features. In addition to the basic touch control function, it also supports more gesture control modes, such as sliding, pinching, rotating and so on. It also enables more complex touch operations.
3. Stability: The stability of GT928 is relatively higher. It uses more advanced circuit design and better quality materials to provide more stable and reliable touch performance, and has a high anti-interference ability.
4. Compatibility: The GT928 is more broadly compatible with different large-screen devices. It can be applied to more operating systems and device types, including different operating system versions and platforms. Overall, the GT928 offers better performance, more features, greater stability, and wider compatibility than the GT911.
The gt911 and gt928 are both common touch chips, but they have some differences in performance and functionality.
1. Performance:
-GT911 has higher touch accuracy and sensitivity to achieve more accurate touch response and operation. The
-GT928 uses more advanced pressure sensing technology than the GT911, allowing for more levels of pressure detection, thus providing more possibilities for user interaction. 2. Function:
-GT911 supports multi-touch, usually including 5-10 touch.
-GT928 not only supports multi-touch, but also supports functions such as pressure sensitivity and palm neglect. Through pressure sensing, users can achieve different degrees of touch force feedback on the touch screen. With the palm Ignore function, the user's palm touch can be ignored to prevent accidental touch. To sum up, the GT928 is more advanced and diversified in performance and features than the GT911. However, the specific choice of which touch chip to use needs to be evaluated and selected according to the specific application scenarios and needs of the product.
GT911, GT928 are GT9 series of non-single-layer multi-touch chips, they support different touch points (GT928 support 10 points, GT911 support 5 points), drive and sensing channels may also be different. However, their registers and IIC communication timing are the same, which means that the drivers are compatible.
INT is the touch signal output pin of GT9xx, in normal operation, the host side should be set to suspension input, that is, not pull up and down (GT9xx drive capacity is limited, if the external pull up and down,GT9xx may not drive).
