Abstract:
Disclosed herein is an electronic paper display device including rotating balls configured of hemispheres having colors that are in complementary relationship with each other. The rotating balls are selectively combined, thereby making it possible to represent red, green, blue, cyan, magenta, and yellow colors to the outside and control brightness and saturation of the colors.
Abstract:
There is provided a device for mounting an electronic paper display element, the device including: a first roller formed to pass over a substrate in which display elements are to be mounted and mounting the display elements in the substrate by moving the display elements backwards, while moving in a predetermined direction above the substrate and rotating in the moving direction; and a second roller mounting the display elements in the substrate by rotating in a direction opposite to that of the first roller to move the display elements forward, while being disposed behind the first roller and moving in the same direction as that of the first roller.
Abstract:
There is provided a method of manufacturing electronic paper, the method including: preparing a substrate having a plurality of accommodating holes in order to accommodate electronic paper display elements; injecting insulating liquid into the individual accommodating holes; increasing the height of partitions forming the accommodating holes by mounting a mask on the partitions, the mask providing through-holes having a size similar to that of the accommodating holes; putting the electronic paper display elements into the accommodating holes; removing extra electronic paper display elements in excess of a predetermined number thereof by a removal unit in order that the predetermined number of electronic paper display elements are put into the accommodating holes; and removing the mask mounted on the partitions after the extra electronic paper display elements are removed from the accommodating holes.
Abstract:
There is provided an electronic paper display device and a manufacturing method thereof. The electronic paper display device includes a first electrode formed of a transparent material; at least one or more second electrodes disposed to face the first electrode with differing gaps therebetween; and at least one or more display units disposed between the first and second electrodes and having optical properties varied according to voltage applied to the first and second electrodes. The display units are disposed between the first electrode and the second electrodes disposed to face the first electrode with differing gaps, so respective rotation amounts or rotation angles of the display units become different when the same magnitude of voltage is applied. Accordingly, a wide range of contrast levels is displayed.
Abstract:
A cooking apparatus includes a case in which a cooking chamber for cooking food is provided, a heating source provided in the case, a fan configured to circulate air in the cooking chamber; and a plasma discharger provided in the case and configured to generate plasma in order to remove residue from a surface of the case.
Abstract:
Provided is a shadow mask including a substrate; a mask that is formed to have an opening for transferring a thin film onto the substrate in a desired shape; and a delamination-preventing polymer layer formed on the mask.
Abstract:
A door assembly for an oven includes a door configured to open and close a heating chamber of an oven, and a glass substrate removably mounted to a surface of the door facing the heating chamber. An oven includes a housing having a heating chamber formed therein for irradiation of microwaves into the heating chamber. A door is configured to open and close the heating chamber, the door having a filter that prevents microwaves from leaking from the heating chamber. A glass substrate is removably mounted to a surface of the door facing the heating chamber.
