  • Touch Sensitive Element and Display Device Comprising the Same
    Publication number: 20180120941
    Abstract: Provided are a touch sensitive element and a display device including the same. According to the exemplary embodiment of the present disclosure, a touch sensitive element, includes: an electroactive layer which is formed of electroactive polymer (EAP); an electrode which is disposed on at least one surface of the electroactive layer; and a hard coating layer which is disposed on the electroactive layer and the electrode and has a negative coefficient of thermal expansion (CTE). Therefore, vibration effect in a vertical direction is maximized and impact resistance may be improved.

  • Substrate having transparent electrode for flexible display and method of fabricating the same
    Patent number: 9241411
    Abstract: A substrate having a transparent electrode for a flexible display which has flexibility and transparency and is resistant to stress of bending, and a method of fabricating the same are provided. By forming a transparent electrode of nanowires resistant to stress of bending on a substrate formed of a shape memory polymer (SMP) material, an increase in resistance due to bending can be prevented and the original form can be recovered. The method for fabricating a substrate having a transparent electrode for a flexible display includes: applying a nanowire dispersion solution of methanol to a glass substrate to form a nanowire electrode; coating the glass substrate with the nanowire electrode formed thereon, with an acrylic shape memory polymer (SMP) to form an SMP thin film; curing the SMP thin film through UV irradiation to form an SMP substrate; and removing the glass substrate from the SMP substrate.
