  • Patent number: 9293102
    Abstract: A display may have an array of pixels arranged in rows and columns. Each pixel may have a transistor for controlling the amount of output light associated with that pixel. The transistors may be thin-film transistors having active areas, first and second source-drain terminals, and gates. Gate lines may be used to distribute gate control signals to the gates of the transistors in each row. Data lines that run perpendicular to the gate lines may be used to distribute image data along columns of pixels. The gate lines may be connected to gate line extensions that run parallel to the data lines. The data lines may each overlap a respective one of the gate line extensions. Vias may be used to connect the gate line extensions to the gate lines. The gate line extensions may all have the same length.

  • Publication number: 20160042708
    Abstract: This application relates to methods and apparatus for refreshing a display device at various frequencies. Specifically, multiple areas of the display device can be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.

In one suitable arrangement, a gate driver circuit may include multiple gate line driver segments each of which is activated by a separate gate start pulse. Each gate start pulse may only be released at the end of an IFP interval. In another suitable arrangement, dummy gate driver units may be interposed among active gate driver units. Gate output signals may propagate through the dummy gate driver units during the IFP internal. In another suitable arrangement, each active gate driver unit may be provided with a buffer portion that protects at least some transistor in the gate driver unit from undesired stress.

    Abstract: A container system and a monitoring method for the container system are provided. The container system includes a plurality of servers and a master server node. The servers are arranged in N areas. The master server node is coupled to the servers. The master server node selects one of a plurality of servers in an ith area to be a main node of the ith area. The main node collects temperature information of the servers in the ith area to transmit highest temperature information to the master server node. When the master server node cannot connect to the main node, the master server node selects one of other servers connected to the master server node in the ith area to be a replacing node, and adjusts the replacing node to be the main node of the ith area to collect the temperature information in the ith area continuously.

    Abstract: A method for obtaining an external IP address and its network protocol system are provided. A rack system of the network protocol system comprises a rack management controller (RMC), a power distribution unit and at least one node server. When a Dynamic Host Configuration Protocol (DHCP) service is lost in the rack system, a jumper of the rack management controller is detected to obtain an identification code. Then, a first temporary IP address of the rack management controller is obtained based on the identification code and a first table, and a first command package is sent to the power distribution unit by the rack management controller. After the first command package is received by the power distribution unit, an IP assign service is activated to set a second temporary IP address of the node server so that the node server can still communicate with the system management terminal.

  • Publication number: 20140118666
    Abstract: A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support. Lateral movement blocking structures such as circular rings may be used to prevent column spacer lateral movement. Subspacers located over pads may be used to create friction that retards lateral movement. Lateral movement may also be retarded by receiving column spacers in trenches or other recesses formed on a thin-film transistor layer.
