Sie-Hyug Choi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10134820
    Abstract: Provided is an organic light-emitting display device which enables a fast and secure repair process without changing optical characteristics. The organic light-emitting display device includes a lower electrode, an organic emitting layer, an upper electrode and an optical compensation layer which are sequentially stacked. The upper electrode is thinner than the lower electrode. An opening is formed by particles in the organic emitting layer and the upper electrode. The opening caused by the particles is extended between the lower electrode and the organic emitting layer.
    Type: Grant

  • Patent number: 9705106
    Abstract: A flexible organic light emitting display and a method of fabricating the same are disclosed in which flexible organic light emitting display may be realized without a plastic based substrate, and at the same time an ideal WVTR characteristic level for stably driving an organic light emitting element without deterioration may be realized. The flexible organic light emitting display comprises a first ultra-thin film glass substrate that includes aluminum silicide; a thin film transistor (TFT) device arranged on the first ultra-thin film glass substrate; and an organic light emitting element arranged on the TFT element.

  • Patent number: 6762817
    Abstract: Encapsulation material is hardened by exposing with light in an amount sufficient to harden it. A black matrix and step compensating pattern are formed only in a part of an injection opening area through which liquid crystal is injected. In the region where the black matrix and step compensating pattern are formed encapsulation material is not filled. Therefore, light irradiation is not blocked by the black matrix and step compensating pattern when hardening the encapsulation material. In the region where the encapsulation material is filled, the encapsulation material is completely hardened by irradiating light without the black matrix and step compensating pattern and light leakage phenomenon is prevented by mounting the region in the outer case of the LCD device.
