Abstract

A haptic feedback actuator comprising a substrate and an electroactive layer structure disposed on the substrate is provided, wherein the electroactive layer structure comprises an electroactive layerbetween a bottom electrode layer and a top electrode layer, and the electroactive layer structure further comprises a wave-like in a longitudinal direction. The disclosure further relates to a touchscreen comprising the haptic feedback actuator, and a method of producing the touch screen, the method comprising providing the substrate, and disposing the electroactive layer structure on the substrate.

Description

technical field [0001] The present disclosure relates to a haptic feedback actuator, a touch screen including the haptic feedback actuator, and a method for manufacturing the touch screen. Background technique [0002] Touchscreens with haptic feedback have recently been introduced to enhance user experience when interacting with on-screen content. In most cases, tactile feedback is generated by electromechanical or electromagnetic actuators that are installed below the touchscreen and actuate the entire screen. Such an actuator increases the required screen size due to the size of the required electromechanical components. Also, haptic feedback is limited to vibrations across the screen. [0003] Therefore, there is a need to provide an improved tactile feedback actuator. Contents of the invention [0004] It is therefore an object of the present invention to provide an improved haptic feedback actuator and an improved touch screen comprising the haptic feedback actuat...
