    • The present invention provides an organic EL display device which exhibits a long lifetime. In an organic EL display device which includes pixel electrodes formed on a substrate, an insulation partition wall surrounding the pixel electrodes, an organic EL layer formed on the pixel electrodes, and a common electrode formed on the organic EL layer, the common electrode is formed of a transparent conductive film which is made of metal oxide, and an auxiliary electrode which is made of opaque metal containing Zn or Mg as a main component is arranged above the common electrode and at positions where the auxiliary electrode overlaps with the insulation partition wall. The auxiliary electrode may be arranged below the common electrode instead of being arranged above the common electrode.

    • An organic electroluminescence display device is provided that prevents a desiccant from being deteriorated. This organic electroluminescence display device has a superior moisture resistance and forms a high barrier against moisture and oxygen while still keeping the display low profile and lightweight. The organic electroluminescence display includes a laminated material and, across this laminated material, a first flexible substrate and a second flexible substrate. The laminated material is composed of layers, with different conductivities, that constitute an electronic circuit that includes a pair of electrodes across a light-emitting layer. At least one of the first flexible substrate and the second flexible substrate includes a desiccant. The flexible substrate that includes this desiccant includes a metal foil that is a base material on which the desiccant is formed. The desiccant is composed of a plurality of island-like desiccant pieces each separated from other desiccant pieces.
    • 提供一种防止干燥剂劣化的有机电致发光显示装置。 该有机电致发光显示装置具有优异的耐湿性,并且在保持显示器低调和轻便的同时,对水分和氧气形成高阻隔性。 有机电致发光显示器包括层压材料,并且穿过该层压材料,第一柔性基板和第二柔性基板。 叠层材料由不同电导率的层构成,它们构成包括跨越发光层的一对电极的电子电路。 第一柔性基板和第二柔性基板中的至少一个包括干燥剂。 包括该干燥剂的柔性基板包括金属箔,该金属箔是形成有干燥剂的基材。 干燥剂由多个与其它干燥剂片分开的岛状干燥剂片组成。

    • In a display device the possibility that the ratio between a display period for display signals and a display period for blanking signals differs from a preset ratio is eliminated, even when the video data is changed. A display device sequentially supplies blanking data from a data driver circuit which sequentially supplies display signals after a lapse of a given time from starting the supply of the display signals. In the display device, a ratio of display is set based on the blanking data per one frame period. Further, the number of pulses of a horizontal synchronizing signal is measured in one frame period contained in the video data, and a point of time is determined for starting display based on the blanking data in response to pulses of the horizontal synchronizing signal corresponding to the ratio based on a measured value of the number of pulses.
    • 在显示装置中,消除了显示信号的显示周期与消隐信号的显示周期与预设比率不同的可能性,即使视频数据被改变。 显示装置顺序地提供来自数据驱动器电路的消隐数据,数据驱动器电路在开始提供显示信号之后经过给定时间后依次提供显示信号。 在显示装置中,基于每帧周期的消隐数据来设置显示比率。 此外,在包含在视频数据中的一个帧周期中测量水平同步信号的脉冲数,并且响应于对应于视频数据的水平同步信号的脉冲,基于消隐数据确定开始显示的时间点 基于脉冲数的测量值的比率。
