Abstract
The present disclosure provides a haptic rendering device, a method, a display device and a controller. The haptic rendering device includes: a substrate; a first driver arranged on the substrate and configured to vibrate and drive the substrate to vibrate after receiving a first driving signal; a vibration sensor arranged on the substrate and configured to generate a first detection voltage signal according to an amplitude or a frequency at which the first driver vibrates together with the substrate in a case where the substrate vibrates; and a controller configured to output the first driving signal to the first driver, receive the first detection voltage signal, and adjust the first driving signal according to the first detection voltage signal.
