  • Publication number: 20230288739
    Abstract: A privacy device and a privacy display apparatus are provided. The privacy device includes a first substrate, a first privacy electrode, first to fourth pads, a connection electrode, a second substrate, a liquid-crystal layer, a second privacy electrode, and a sealant. The first privacy electrode and the connection electrode are disposed on the first substrate. The first and second pads are coupled to the first privacy electrode. The third and fourth pads are coupled to the connection electrode. The first and second pads are disposed between the third pad and the fourth pad. The liquid-crystal layer and the sealant are disposed between the first substrate and the second substrate. The sealant includes multiple conductors. The connection electrode, the sealant, and the second privacy electrode are in a non-display area and overlap with each other along a direction perpendicular to a top surface of the first substrate.

  • Publication number: 20230262026
    Abstract: A data transmission system and method thereof for edge computing are provided. A terminal mobile station international subscriber directory number (MSISDN) and a terminal IP of a target terminal are obtained with a domain name system (DNS) by a device providing communication services from the data transmission system. After data packets are sent to the data transmission system, if the target terminal is in an idle mode, a paging message is sent by a terminal wake-up module to enable the target terminal to return to a connected mode for communication. Before a connection is established between the data transmission system and the target terminal, downlink data packets can be temporarily stored, and the packets can be sent after the target terminal is in the connected mode. A computer readable medium for executing the data transmission method is also provided.

  • Patent number: 9081241
    Abstract: A pixel structure and a method for manufacturing the same are disclosed. The pixel structure of the present invention is a pixel structure implemented by combining an in-plane switching (IPS) technique and a fringe field switching (FFS) technique. In each pixel structure, two transparent conductive layers are utilized to form a storage capacitor (Cst) such that the capacitance of the storage capacitor can be increased without decreasing an aperture ratio of a display panel, and thereby a feedthrough voltage can be reduced so as to prevent a screen from blinking.

  • Patent number: 8451203
    Abstract: A pixel arrangement method for a liquid crystal display includes the steps of: inputting data signals with different driving polarities to odd data lines and even data lines respectively; and changing connections between a gate of thin film transistor and gate lines and connections between a source of thin film transistor and data lines in every pixel area whereby the driving polarity is inverted every two pixel areas in a transverse direction and is inverted every pixel area in a longitudinal direction. The present invention further provides a liquid crystal display.

  • Publication number: 20100225867
    Abstract: A TFT array substrate includes a plurality of gate lines, common lines, data lines and pixel electrodes. Each common line includes a common electrode which is perpendicular to the gate line and has a first width. The data line has a second width and is perpendicular to the gate line, wherein two adjacent gate lines and two adjacent data lines define a pixel. The pixel electrodes are located in the pixels respectively, wherein the common electrode is overlapped with the data line and a part of the pixel electrode, and the common electrode completely shelters a gap between the pixel electrode and the data line.
