  • Publication number: 20230345748
    Abstract: Disclosed are an organic light emitting device and a display device using the same in which a light emitting layer includes a host and a plurality of dopants. In the light emitting layer, energy is transferred from a host and other dopants to one dopant by energy transfer system, thus it is possible to increase luminous efficacy of a single color and to increase lifetime of emission.
    Type: Application

  • Patent number: 11730013
    Abstract: Disclosed is a display panel configured such that, in a structure in which the distance between a display surface and a viewer is short, the structure between a reflective plate and a first electrode (an anode) is changed such that light having three or more color peak properties for all subpixels is transmitted through a second electrode (a cathode), whereby white expression as well as color expression is possible, and a head mounted display device including the same.

  • Publication number: 20140067746
    Abstract: Disclosed are an apparatus and method for managing user-centered context, the apparatus including a sensor level unit including a plurality of sensors to transmit respective pieces of first context collected from the plurality of sensors, a domain level unit including a plurality of domain context management modules (domain_U-CoUDE) to produce a first inferred context by aggregating and inferring a corresponding second context among the respective pieces of first context by use of a context model and transmit the produced first inferred context, and a user level unit including a plurality of user context management modules (user_U-CoUDE) to produce and transmit a second inferred context by aggregating and inferring the first inferred context by use of the context model, so that different forms of context generated from various domains are converted into a standardized from, thereby providing and using the context in a more efficient manner.
