Touch orientation

The Touch of the LCD cannot be changed along with the display, in this case, you should rotate the touch manually after changing the display orientation. With this display, you can rotate the touch by using a card needle or tweezer and pressing the following button.
(To avoid unintended touching, we hide the Rotate Touch button in the case)
