摘要： The present invention relates to an encapsulation for an electronic thin film device, comprising a first barrier layer (108), a second barrier layer (112), and a first planarization layer (110′) for reducing the formation of pinholes in a subsequent barrier layer, said first planarization layer (110′) arranged between the first barrier layer (108) and the second barrier layer (112), wherein the first planarization layer (110′) is composed of a first plurality of planarization segment (114) having areas formed between each other, and the encapsulation further comprises a second planarization layer (116) arranged between the second barrier layer (112) and a third barrier layer (120), wherein the second planarization layer (116) is composed of a second plurality of planarization segments (118) arranged to extend over the areas between the first plurality of planarization segments (114), thereby further reducing the number of pinholes providing passageways through the encapsulation. According to the invention, by arranging the barrier layers and the planarization layers in a horizontal multi-layer encapsulation stack, where planarization segments in each of the layers are essentially decoupled from each other and in practice non-interconnecting with each other, it is possible to limit the lateral transportation of water and oxygen through the planarization layer. Instead, if water/oxygen enters the top barrier layer, and eventually a planarization segment, it is contained in the “sphere” of a planarization segment, having a minimized possibility of entering a pinhole in a subsequent barrier layer. The present invention also relates to corresponding method for the formation of an encapsulation for an electronic thin film device.

摘要： The invention provides a tool to select reliable organic LED devices, where the risk for failure before the end of its lifetime is low. This tool comprises the steps of: i) subjecting the device to a high electric field over the electroluminescent layer. This leads to a division of the devices into two, clearly separated, populations, namely one population with a low leakage current (current through the electroluminescent layer in reverse voltage operation) and one population with a high leakage current. In this step, the first population is selected in accordance with a current criterion. ii) detecting instabilities in the leakage current, referred to as noise. It has been established that these instabilities arise in particular at reverse driving voltages between 1 and 10 Volts. These instabilities are a measure of the occurrence of early failures during operation. In this step, the devices are selected in accordance with a noise criterion.

摘要： A method for driving an organic LED display device having a first and a second electrode sandwiching an organic layer defining a plurality of light emitting elements. The method comprises applying to a light emitting element a voltage within a specified voltage range, within which the risk of short circuits between the electrodes is reduced, and controlling the duty cycle of said light emitting element, so that a desired light intensity is emitted from said light emitting element. The probability of short circuits in pixels of an organic LED display device is thus reduced by avoiding operating the display pixels within voltage ranges where the chance of short circuits is high. This limitation of the applied voltage is compensated by controlling the duty cycle of the light emitting element.

摘要： The invention relates to OLEDs (1) having a substrate (2), a first electrode layer (3), a layer of organic electroluminescence material (4), a second electrode layer (5), a cover layer (6), moisture-absorbing means (9) and a separating foil (10) of resilient material. According to the invention, said foil (10) is positioned between the second electrode layer (5) and the moisture-absorbing means (9). This feature results in a longer mean life-time of the OLED. Advantageously spacer structures (12) (preferably formed as dots) are applied on the separating foil (10) between the foil (10) and the cover (6). This prevents discoloring effects around the rim of the OLED material.
