Abstract
A display module having a haptic function includes a touch screen panel for detecting touch manipulation, a liquid crystal display (LCD) panel for realizing image display on the touch screen panel, a backlight unit comprising at least one light source for providing illuminating light to the LCD panel, and a haptic actuator disposed adjacent to the light source for providing a haptic effect. The display module having a haptic function has improved space effectiveness, and is easily miniaturized and thinned.
