    Abstract: An electrowetting display device includes an electrowetting pixel cell and a driving circuit. The electrowetting pixel cell including a polar liquid and a non-polar liquid disposed between a common electrode and a pixel electrode, the pixel electrode configured to receive a fixed voltage and the common electrode configured to receive a variable voltage that varies according to an image signal. The driving circuit configured to control an operation of the electrowetting pixel cell by, providing an image signal to the electrowetting pixel cell at a display interval where the electrowetting pixel cell displays an image, and providing a reset voltage to the electrowetting pixel cell at a reset interval. An absolute value of a difference between the voltage applied to the pixel electrode and the reset voltage is greater than that of a difference between the voltage applied to the pixel electrode and the voltage applied to the common electrode.

    Abstract: An electrowetting display apparatus includes an electrowetting pixel configured to display an image. The electrowetting pixel includes a polar liquid and a nonpolar liquid arranged between a common electrode and a pixel electrode; and a driving circuit configured to control operations of the electrowetting pixel. The driving circuit includes a memory circuit configured to store an image to be displayed by the electrowetting pixel. The driving circuit is further configured to periodically provide a reset signal to the electrowetting pixel while the electrowetting pixel is displaying the image and provide an image stored in the memory circuit to the electrowetting pixel after the electrowetting pixel cell resets.

    Abstract: Provided is an image sensor having a hybrid pixel structure in which pixels that sense visible light and pixels that sense ultraviolet light or infrared light are arranged together. For example, the image sensor includes a plurality of first pixels and a plurality of second pixels that are different in size. A width of each of the plurality of second pixels in a horizontal direction is a first integer multiple of a width of each of the plurality of first pixels in the horizontal direction, and a width of each of the plurality of second pixels in a vertical direction is a second integer multiple of a width of each of the plurality of first pixels in the vertical direction. The image sensor enables the pixels sensing ultraviolet light or infrared light, which have different sizes from the pixels sensing visible light, to be efficiently arranged together with the pixels sensing visible light, on the same substrate.
