  • Publication number: 20200234044
    Abstract: The present disclosure relates to image signal processing methods, apparatus, and devices. One example image signal processing method includes obtaining an image signal, where the image signal is derived based on a sensor signal collected by an image sensor, recognizing, by using a neural network, a scene to which the image signal belongs, determining, by using attribute information of the image signal, whether the scene is accurate, and in response to determining that the scene is accurate, performing enhancement processing on the image signal based on the scene to generate an enhanced image signal.

  • Patent number: 10707347
    Abstract: The various described embodiments provide a transistor with a negative capacitance, and a method of creating the same. The transistor includes a gate structure having a ferroelectric layer. The ferroelectric layer is formed by forming a thick ferroelectric film, annealing the ferroelectric film to have a desired phase, and thinning the ferroelectric film to a desired thickness of the ferroelectric layer. This process ensures that the ferroelectric layer will have ferroelectric properties regardless of its thickness.

  • Publication number: 20200135272
    Abstract: A method is disclosed including following operations. A first signal is applied to memory cells in a memory device, to adjust resistance values of the memory cells. After the first signal is applied, a second signal is applied to the memory cells other than the first memory cell, to further adjust the resistance values of the plurality of memory cells other than the first memory cell. After the second signal is applied, data corresponding to the first predetermined resistance value and the second predetermined resistance value is stored in the first memory cell and the second memory cell, respectively. The first signal is configured for controlling a first memory cell in the memory cells to have a first predetermined resistance value. The second signal is configured for controlling a second memory cell in the memory cells to have a second predetermined resistance value.

    Abstract: The invention includes a glass plate, a bezel layer, a touch sensor layer and a signal wire layer. The bezel layer attached on a periphery of the glass plate defines a shaded area and a visible area. The touch sensor layer has sensing columns arranged in the visible area. Each of the sensing columns includes a common sensing electrode and a plurality of driving electrodes. The driving electrodes are divided into two electrode columns. Each driving electrode of the electrode columns is connected to a bridging point in one of two opposite side of the shaded area through a connecting wire. All the bridging points in a line are electrically connected by a bridging film connected to a part of the contacts of the connecting port through the signal wire layer. The common sensing electrodes are electrically connected to another part of the contacts through the signal wire layer.
