Because capacitive touch uses an absolute coordinate system, the GT9XX automatically maps touches to the 1024x600 grid. However, you must ensure the framebuffer rotation matches the touch orientation. If the display is rotated 90°, use xinput set-prop or a udev rule to rotate the touch input matrix.

This combination is widely adopted by leading embedded solution providers like , which uses GT9xx drivers for its 4.3-inch and 10.1-inch LCDs, Flylink (飞凌嵌入式) , Forlinx , and various industrial display manufacturers. gt9xx1024x600

The specific GT9xx model used often depends on the screen size and the number of required touch points. For a standard 1024x600 panel, the following models are most common: Part Number Touch Points Sensing Channels Target Screen Size 26 Tx * 14 Rx ≤is less than or equal to GT9271 32 Tx * 20 Rx ≤is less than or equal to GT928 32 Tx * 24 Rx ≤is less than or equal to GT9110 42 Tx * 30 Rx ≤is less than or equal to Key Features and Capabilities
