  • Publication number: 20200393715
    Abstract: Electrical shield line systems are provided for openings in common electrodes near data lines of display and touch screens. Some displays, including touch screens, can include multiple common electrodes (Vcom) that can have openings between individual Vcoms. Some display screens can have an open slit between two adjacent edges of Vcom. Openings in Vcom can allow an electric field to extend from a data line through the Vcom layer. A shield can be disposed over the Vcom opening to help reduce or eliminate an electric field from affecting a pixel material, such as liquid crystal. The shield can be connected to a potential such that electric field is generated substantially between the shield and the data line to reduce or eliminate electric fields reaching the liquid crystal.

  • Publication number: 20200383051
    Abstract: A power control method of a base station in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA) is provided for reducing power consumption by turning off the bias of the power amplifier for the duration of a symbol carrying no user data. The method includes checking scheduling information of radio resources, detecting a symbol carrying no user data, based on the scheduling information, and turning off a bias of the power amplifier for a symbol duration of the symbol carrying no user data. The transmission power control method is capable of reducing power consumption of the base station by turning off the bias of the power amplifier of the base station for the symbol duration in which no user data is transmitted.

    Abstract: The present disclosure relates to a method for inducing pluripotent stem cells by inducing reprogramming and/or dedifferentiation of differentiated adult cells using shikimic acid, a plant extract or plant stem cells containing shikimic acid and an extract of dedifferentiated stem cells (callus), pluripotent stem cells prepared by the method and a composition containing the pluripotent stem cells. In accordance with the present disclosure, ethical concerns implicated with the use of eggs to prepare pluripotent stem cells such as embryonic stem cell can be resolved. And, because the plant stem cell extract unharmful to human is used, pluripotent stem cells with proven safety can be prepared and they may be used to develop immunocompatible cell therapy agents suited for individuals. In addition, by pluripotent stem cells from individuals having diseases, the present disclosure will be very useful in studying the cause of diseases and devolving therapeutic strategy.

  • Patent number: 10223975
    Abstract: An electronic device may be provided with an organic light-emitting diode display. The display may include row driver circuitry that provides an emission control signal at an output terminal to display pixels. The emission control signals may enable or disable light emission by the pixels. The row driver circuitry may include a bootstrapping capacitor that stores charge for boosting a gate signal at an intermediate node for a pull-up transistor above a power supply voltage. The row driver circuitry may include a pull-down transistor coupled to the intermediate node. The source terminal of the pull-down transistor may be coupled to the output terminal or an additional pull-down transistor may be stacked with the pull-down transistor to reduce leakage current. Charge pump circuitry may be coupled to the intermediate node to ensure that the intermediate node is maintained at a voltage above the power supply voltage.
