    • A display device comprises a light emitting picture element (120) and a contrast enhancing element (110). The contrast enhancing element comprises a plurality of wave guides (216) separated by interstitial regions (212) being formed as narrowing recesses. An interface between a wave guide (216) and an interstitial region (212) is provided with a reflective layer. The narrowing recesses form a dead end for incident ambient light which is efficiently absorbed by the contrast enhancing element. On the other hand, light emitted by the picture element (120) of the display device is transmitted through the wave guides (216). As a result, the display device has a relatively high contrast ratio, particularly under bright ambient light conditions.
    • 显示装置包括发光图像元件(120)和对比度增强元件(110)。 对比度增强元件包括由间隙区域(212)分离的多个波导(216),其形成为狭窄的凹部。 波导(216)和间隙区(212)之间的界面设置有反射层。 变窄的凹槽形成入射环境光的死角,该光源被对比度增强元件有效地吸收。 另一方面,由显示装置的像素(120)发射的光通过波导(216)传输。 结果,显示装置具有相对高的对比度,特别是在明亮的环境光条件下。

    • A disk drive unit for a removable disk (D), in particular for use in mobile devices, comprises a spindle (1) driven by an electric motor (2) and supporting the disk (D) in its operating position. It further comprises one or two loading mechanisms (4A and 4B) to load mechanical energy into a storage mechanism (5) for storing the loaded energy. A release mechanism (6) is provided to release the stored energy stepwise to the spindle in order to assist during a plurality of start-ups of the disk rotation. The two loading mechanisms (4A and 4B) are adapted to load mechanical energy provided by the user during insertion of the disk and energy released during the deceleration of the rotation of the disk, respectively. The electrical power consumption of the disk drive unit is reduced by the storage of the mechanical energy and its stepwise release.
    • 用于可移动盘(D)的磁盘驱动器单元(D)特别用于移动设备中,包括由电动机(2)驱动并将盘(D)支撑在其操作位置的主轴(1)。 它还包括一个或两个加载机构(4A和4B),以将机械能装载到用于存储所加载的能量的存储机构(5)中。 提供释放机构(6)以逐步释放存储的能量到主轴,以便在盘旋转的多次启动期间进行协助。 两个装载机构(4A和4B)分别适用于在盘的插入期间分别由用户提供的机械能和在盘的旋转减速期间释放的能量。 通过存储机械能及其逐步释放来减少磁盘驱动单元的电力消耗。
