Unanswered Questions
How does this technology compare to existing light decreasing layers in terms of efficiency and cost-effectiveness?
This article does not provide a direct comparison with existing light decreasing layers in terms of efficiency and cost-effectiveness. Further research or comparative studies would be needed to address this question.
What are the environmental implications of using inorganic materials in the external light decreasing layer?
The article does not discuss the environmental implications of using inorganic materials in the external light decreasing layer. A separate study on the environmental impact of such materials would be necessary to answer this question.
Original Abstract Submitted
A light emitting display device according to an embodiment includes a driving element layer disposed on a substrate, a light emitting element layer disposed on the driving element layer, and an external light decreasing layer disposed on the light emitting element layer. The light emitting element layer includes an anode, a pixel defining film having a first opening exposing at least a portion of the anode, a light emitting layer disposed on the anode in the first opening of the pixel defining film, and a cathode disposed on the light emitting layer and the pixel defining film. The external light decreasing layer includes an inorganic material having an absorption coefficient of greater than or equal to about 1.5, and includes a reflection control layer having a second opening corresponding to the first opening of the pixel defining film.
