  • Patent number: 10636356
    Abstract: Electronic devices may include displays having organic light-emitting diode pixels, display driver circuitry, and gate driver circuitry. To reduce the amount of space occupied in the inactive area of a display by the gate driver circuitry, one or more of the shift registers in the gate driver circuitry may include register circuits that are shared by multiple rows of pixels. Different drivers may use different clock frequencies to ensure synchronous operation of the display even when some register circuits share pixel rows. For increased flexibility in the arrangement of the register circuits in the shift registers, one or more of the shift registers may be split across the active area of the display. In some cases, one of the emission drivers may be omitted from the gate driver circuitry and a single emission driver may provide multiple emission control signals for the pixels.

  • Patent number: 10599265
    Abstract: Provided is an electronic device including an input means using a touch panel with which incorrect operations is reduced. When people whose arms, hands, or fingers involuntarily shake because of cerebral palsy or the like use an input system including a touch panel, incorrect touch might occur in input operation. To prevent this, a touch input system in which a cover for preventing incorrect touch is provided over a touch panel to reduce incorrect operations is provided. However, since there is a region that is hard to touch using the cover, electronic devices including such touch panels are not sufficiently widely used. Thus, novel touch panels are provided outside a display region where the cover is provided. The touch panels have a function of selecting first and second regions. The first and second regions intersect with each other to provide a third region. A display object displayed in a region overlapping with the third region is configured to be extracted and executed.

The light-sensor array can be one or more of transparent, bendable, and implemented on a curved surface. In some embodiments, the wavelength-selective light-sensing opto-electronic elements are arranged in a stacked array.
