    • A system and method are disclosed for reducing reverse bias in an electrophoretic display. The system and method include the application of varying levels of voltages across an array of electrophoretic display cells of the electrophoretic display to move the cells towards a stable state in a driving cycle. In addition, the system and method disconnect the voltages from the electrophoretic display cells at a time duration prior to reaching step transitions of the voltages during the driving cycle. Pre-driving approaches apply a first pre-driving voltage at a first polarity to the display cells before driving the display cells with a second driving voltage at a second, opposite polarity. Varying the time duration and amplitude of the pre-driving signals produces further beneficial reduction in reverse bias.
    • 公开了用于减少电泳显示器中的反向偏压的系统和方法。 该系统和方法包括在电泳显示器的电泳显示单元的阵列上应用不同电平的电压,以在驱动循环中将单元移动到稳定状态。 此外,该系统和方法在驱动周期期间电压达到阶跃转换之前的时间段中断开电泳显示单元的电压。 在以第二极性相反的第二驱动电压驱动显示单元之前,预驱动方法将第一极性的第一预驱动电压施加到显示单元。 改变预驱动信号的持续时间和幅度产生反向偏置的进一步有益的减少。

    • Electronic devices such as computers and handheld devices are provided. The electronic devices may have electrical components such as displays that are driven by driver circuitry. During operation, the driver circuitry may generate radio-frequency noise. Communications circuitry in the electronic devices may be shielded from the radio-frequency noise by radio-frequency shielding structures. The shielding structures may be mounted on portions of the display module, on a cover glass layer, or on other structures such as housing structures. The radio-frequency shielding structures may be formed from one or more metal segments. The metal segments may run along edges of the display. A device housing may have a ground formed from a conductive peripheral member that runs around peripheral edges of the housing and a conductive plate that is connected to the conductive peripheral member. The radio-frequency shielding structure may be connected to the ground using conductive structures.
    • 提供诸如计算机和手持设备之类的电子设备。 电子设备可以具有诸如由驱动器电路驱动的显示器的电气部件。 在操作期间,驱动器电路可能产生无线电频率噪声。 电子设备中的通信电路可以通过射频屏蔽结构屏蔽射频噪声。 屏蔽结构可以安装在显示模块的一部分上,覆盖玻璃层上,或其它结构上,如外壳结构上。 射频屏蔽结构可以由一个或多个金属片段形成。 金属片段可以沿着显示器的边缘延伸。 设备壳体可以具有由围绕壳体的周边边缘延伸的导电周边构件形成的接地和连接到导电周边构件的导电板。 射频屏蔽结构可以使用导电结构连接到地面。
