    摘要: An electroluminescent display includes a lower substrate having a display area with subpixel emission areas defined in the display area; an electrode layer on the lower substrate; a planarization layer formed on the lower substrate such that holes are formed in the planarization layer with each hole being adjacent to a respective one of the subpixel emission areas; lower electrode layer in the respective subpixel emission area; a sacrificial layer surrounding the subpixel emission area and absent at an area having the lower electrode layer; an organic emission layer on the lower electrode layer; and an upper electrode layer on the organic emission layer.

    摘要: The present disclosure relates to a large area organic light emitting diode display and a method for manufacturing the same. A photoresist is deposited across first and second pixel areas of the display. The photoresist is patterned to generate a patterned photoresist by stripping away first portions of the photoresist in the first pixel areas while keeping second portions of the photoresist in the second pixel areas. An organic emission layer is deposited across the first and second pixel areas over the patterned photoresist. An electron transport layer is deposited across the first pixel areas and the second pixel areas over the organic emission layer. Portions of the organic emission layer and the electron transport layer in the second pixel areas are removed by stripping away the second portions of the photoresist while keeping portions of the organic emission layer and the electron transport layer in the first pixel areas.

    摘要: An organic light emitting diode display device is discussed. The organic light emitting diode display device includes pixels including an organic light emitting diode, and a bank partitioning the pixels which are neighboring, and having openings exposing at least a portion of a first electrode of the organic light emitting diode allocated for each of the pixels. The bank includes at least one groove provided between the neighboring pixels in at least one area.
