  • Patent number: 11445138
    Abstract: A solid-state imaging device configured to suppress fixed pattern noise having column correlation and/or lateral correlation from being generated in images is disclosed. In one example, a solid-state imaging device includes unit pixels arranged in row and column directions, vertical signal lines respectively connected to at least one of the unit pixels arranged in the column direction, first converters connected to the respective vertical signal lines and configured to convert an analog pixel signal into a digital pixel signal in reading each unit pixel arranged in the row direction, an initialization voltage generator that outputs an initialization voltage for initializing the unit pixels or input nodes of the first converters, and an initialization voltage line that connects the initialization voltage generator and the first converters. The initialization voltage generator changes the initialization voltage that is output for each row and/or column to be processed by the first converters.

  • Patent number: 11340509
    Abstract: A display device includes a display panel, and a front panel overlapping with the display panel and being switched into a reflection state in which incident light is reflected and a transmission state in which incident light is transmitted. The front panel includes a first substrate, a second substrate facing the first substrate, a liquid crystal layer sealed between the first substrate and the second substrate, a first translucent electrode provided on a side of the first substrate on which the liquid crystal layer is located, a second translucent electrode provided on a side of the second substrate on which the liquid crystal layer is located, a discharge resistor that is electrically coupled to the second translucent electrode and is provided on the second substrate, and a first conductive pillar that electrically couples the first translucent electrode and the discharge resistor.

  • Patent number: 8434122
    Abstract: The invention relates to a device for delivering audio and video data. In such a device, the audio/video data travel together and are compressed along with the signaling data for the delivery of these audio/video data. Under current compression standards, these data are being increasingly compressed. This maximum compression proportionally complexifies the encoding and decoding of audio/video data. The appearance of network cables comprising six twisted pairs of wires makes it possible to produce networks having higher speed capacities. The object of the invention is not to increase speeds by using additional twisted pairs but to simplify the data traveling through the network.
