  • Patent number: 11921370
    Abstract: Disclosed are a display panel and a method of manufacturing a display panel. The display panel includes an array substrate; a color film substrate disposed opposite to the array substrate; a liquid crystal layer disposed between the array substrate and the color film substrate; a reflective layer disposed on a side of the array substrate facing the liquid crystal layer. The reflective layer comprises a plurality of first convex structures, each of the first convex structures has a first sidewall extending from a bottom to a top of each of the first convex structures, and an angle between a normal line of the first sidewall and a horizontal plane is greater than 0° and less than or equal to 10°.
    Type: Grant

  • Patent number: 11841597
    Abstract: The present disclosure provides an array substrate and a display panel including the same. The array substrate includes a plurality of pixel units. Each of the pixel units includes a main pixel electrode, a sub-pixel electrode, a first thin film transistor (TFT) electrically connected to the sub-pixel electrode, a second TFT electrically connected to the first TFT, and a third TFT electrically connected to the main pixel electrode. The first TFT includes a first channel and a first semiconductor layer. The first channel includes two or more subchannels. The first semiconductor layer includes two or more semiconductor sublayers. Each of the semiconductor sublayers is disposed in a corresponding subchannel.

  • Publication number: 20210218595
    Abstract: Described herein are embodiments for dual-port communication and power delivery for one-wire applications. Embodiments of one-wire bridge devices are disclosed to provide a dual-port link for two one-wire masters to communicate with one another in a multi-voltage system while intermittently allowing charging voltage. The configuration may be used to set a bidirectional pass through mode that allows level shifted fast logic signals to pass through the two one-wire links. A timer may also be configurable to time-out the pass through mode from edge in-activity. Power may be derived for operation directly from one of the links, eliminating the need for an external power supply when local power is not available. When local power is available, the other one-wire link provides local access and the pass through mode. Such configurations make it easy for a two-contact solution to be both a communication channel and a power supply for battery charging.
