20110079797 | DISPLAY DEVICE - A display device includes an array of pixels including a plurality of organic EL elements each having a pair of electrodes and an organic compound layer including a light-emitting layer and disposed between the pair of electrodes and includes a protective layer disposed on the plurality of the organic EL elements. The protective layer has a first protective layer made of an inorganic material, a second protective layer made of a resin material and disposed on the first protective layer, and a third protective layer made of an inorganic material and disposed on the second protective layer. The second protective layer includes lenses for diverging at least part of light emitted from the light-emitting layer. The lenses have an elongated concave shape. | 04-07-2011 |
20120032590 | ORGANIC ELECTROLUMINESCENCE DISPLAY APPARATUS - An organic EL display apparatus includes a plurality of pixels and a lens array which includes a light-condensing lens portion and a flat portion disposed on the light-emitting surface side of each pixel. Each pixel includes a light-emitting layer contained between a pair of electrodes. Part of the light emitted from the light-emitting layer is condensed by the light-condensing lens portion. A top surface of the light-condensing lens portion overlies the light-emitting region, and a part of the light-condensing lens portion is located outside the light-emitting region. | 02-09-2012 |
20120074391 | DISPLAY DEVICE - A pixel unit having two or more pixels different in emission color is provided with lenses in such a manner that the difference of the angular dependence of brightness in organic EL elements for every emission color of the pixels becomes small. | 03-29-2012 |
20120199859 | ELECTROLUMINESCENT DISPLAY APPARATUS - A display apparatus includes an organic electroluminescent element, a protective layer provided in contact with the organic electroluminescent element and configured to cover the organic electroluminescent element, and a condenser lens provided in contact with the protective layer and on a light output side of the organic electroluminescent element. The condenser lens includes a convex surface having a sloping angle θ | 08-09-2012 |
20120299883 | ORGANIC ELECTROLUMINESCENT DISPLAY APPARATUS - An organic electroluminescent (EL) display apparatus includes a plurality of pixels each having a first region and a second region of the same hue. The first region and the second region each include an organic EL element including a first electrode, an organic EL layer including a light-emitting layer, and a second electrode. The second region further includes a lens disposed on the light exit side of the second electrode. The organic EL element in the second region in at least part of the pixels is configured to meet 0.9<2L/λ+φ/2π<1.1. | 11-29-2012 |
20130001609 | DISPLAY APPARATUS - In a display apparatus including an organic EL element utilizing the optical interference effect, and a lens, a diameter of the lens is set such that, of light radiated from the organic EL element into a protective layer, light radiated at a larger angle than an angle, at which a light intensity distribution of the light radiated into the protective layer with respect to a radiation angle of the light takes a local minimum value, is not output to the outside of the display apparatus. | 01-03-2013 |
20130002130 | DISPLAY APPARATUS - In a display apparatus including an organic EL element utilizing the optical interference effect, and a lens, a light absorbing layer is disposed such that, of light radiated from the organic EL element into a protective layer, light radiated at a larger angle than an angle, at which a light intensity distribution of the light radiated into the protective layer with respect to a radiation angle of the light takes a local minimum value, is not output to the outside of the display apparatus through the lens. | 01-03-2013 |
20130277659 | DISPLAY DEVICE - A display device includes an array of pixels including a plurality of organic EL elements each having a pair of electrodes and an organic compound layer including a light-emitting layer and disposed between the pair of electrodes and includes a protective layer disposed on the plurality of the organic EL elements. The protective layer has a first protective layer made of an inorganic material, a second protective layer made of a resin material and disposed on the first protective layer, and a third protective layer made of an inorganic material and disposed on the second protective layer. The second protective layer includes lenses for diverging at least part of light emitted from the light-emitting layer. The lenses have an elongated concave shape. | 10-24-2013 |
