• Light source with organic layer and photoluminsecent layer

  A light source (200) comprises an organic light emitting device (100) which emits radiation having a first spectrum and a phosphor layer (115) which absorbs a portion of the light emitted by the organic light emitting layer (100) and which emits light having a second spectrum. The phosphor layer (115) typically absorbs less than all of the light emitted by the organic light emitting layer (100) and typically covers the entire organic light emitting device (100). The light emitted by the organic light emitting layer (100) is mixed with the light emitted by the phosphor layer (115) to produce light having a third spectrum.. Exemplary embodiments of the invention provide advantages over known devices For example, because a phosphor layer (115) is provided, the light emitted from the organic light emitting device (100) is scattered, which provides improved uniformity in light output over the area of the light source (200). Also, because most phosphors are relatively stable over time, the light source (200) has good color stability over time.

  光源（200）包括有机发光器件（100）和荧光粉层（115），前者发出具有第一光谱的辐射，后者吸收有机发光层（100）发出的部分光，并发出具有第二光谱的光。荧光粉层（115）吸收的光通常少于有机发光层（100）发出的全部光，通常覆盖整个有机发光器件（100）。有机发光层（100）发出的光与荧光粉层（115）发出的光混合，产生具有第三光谱的光。与已知设备相比，本发明的示例性实施例具有优势。例如，由于提供了荧光粉层（115），有机发光器件（100）发出的光会发生散射，从而改善了光源（200）区域内光输出的均匀性。此外，由于大多数荧光粉在一段时间内相对稳定，因此光源（200）在一段时间内具有良好的色彩稳定性。
• Luminescent display and method of making

  The invention relates to a luminescent display comprising a first electrode, a second electrode, an organic light emitting layer disposed between the first and second electrodes, and a luminescent material which receives light from the organic light emitting layer and converts the light to a different wavelength, wherein the first and second electrodes together define an overlap region in which the organic light emitting layer is activated to emit light, and the luminescent material is disposed in a portion of the overlap region. The invention also relates to a method comprising the steps of creating an image and printing the image on a light emitting device comprising an organic light emitting layer after the light emitting device has been formed. The image may be created, for example on a personal computer, and printed with an inkjet printer. The image may be printed in phosphors which emit light of one wavelength upon absorbing light of a different wavelength from the organic light emitting layer. Various embodiments of the invention allow customized luminescent displays to be easily fabricated by end users by applying a phosphor pattern to a preformed, encapsulated light emitting device.

  本发明涉及一种发光显示器，包括第一电极、第二电极、设置在第一电极和第二电极之间的有机发光层，以及接收来自有机发光层的光并将该光转换为不同波长的发光材料，其中第一电极和第二电极共同限定了一个重叠区域，在该重叠区域中，有机发光层被激活以发光，而发光材料被设置在重叠区域的一部分中。本发明还涉及一种方法，包括以下步骤：在发光器件形成后，在包含有机发光层的发光器件上创建图像并打印图像。图像可以在个人电脑等设备上创建，并用喷墨打印机打印。图像可以用荧光粉打印，荧光粉吸收有机发光层发出的不同波长的光后，会发出一种波长的光。 本发明的各种实施方案允许最终用户通过将荧光粉图案应用到预制封装发光器件上，轻松制造出定制的发光显示器。
