Abstract: A droplet-based energy harvester is proposed. The droplet-based energy harvester may include a plate comprising a first surface and a second surface opposite to the first surface while being inclined such that a droplet flows on the first surface. The harvester may also include an upper electrode formed on the first surface, and a lower electrode formed on the second surface. The upper electrode may include a first upper electrode and a second upper electrode. The first upper electrode may be configured to emit electrons when the first upper electrode is connected to the second upper electrode by the droplet. The second upper electrode may be configured to absorb the electrons when the second upper electrode is connected to the first upper electrode by the droplet.

Abstract: A hybrid display is disclosed. The hybrid display includes an electrophoretic module configured to display information through reflection of light incident from an exterior thereof, and a light emitting module formed at a lower surface of the electrophoretic module, to output color light to the electrophoretic module. The electrophoretic module includes a first substrate, a second substrate spaced apart from the first substrate, a plurality of capsules disposed between the first substrate and the second substrate, each of the capsules containing particles having a color and a fluid having a color therein, and an electrode configured to apply an electric filed to the capsule, thereby moving the particles. The color light output from the light emitting module is mixed with the color of the fluid, and is then outwardly output. The hybrid display exhibits excellent visibility even in a dark environment, and the background color thereof is variously changeable.

Abstract: A display panel and a method of manufacturing the same are disclosed. The display panel includes a display area configured to display an image, and a curved area formed at a part or the entirety of the display area. The display area includes a first substrate, at least one first heat dissipation layer formed on the first substrate, a capsule layer disposed on the first heat dissipation layer while including a plurality of capsules configured to represent a color, a second heat dissipation layer formed on the capsule layer and made of a transparent material, and a second substrate formed on the second heat dissipation layer and made of a transparent material. The display panel may not be broken by heat even when the display panel having a flat structure is subjected to thermoforming.

Abstract: Provided are a color change module using a reflective display, and an independent type color change control apparatus providing an electrical signal for changing a color of the color change module. The color change module can include a module base, the reflective display, a first external electrode and a second external electrode. The module base has a shape corresponding to an object for attachment. The reflective display is provided on an upper surface of the module base, and displays information in a manner wherein light coming from outside is reflected. The first external electrode and the second external electrode are provided to be connected to the reflective display and to be exposed to outside for receiving the information to be displayed on the reflective display from the independent type color change control apparatus.
