  • Publication number: 20240119894
    Abstract: A display apparatus includes: a display; a display driver that drives the display such that the display displays in accordance with display data; and a host controller that transfers update display data of one screen to the display driver. The display driver includes a light-emission controller that causes a self-luminous elements to emit light, and a memory that stores the update display data of the one screen. The display driver reads the update display data on the memory after an elapse of a predetermined period of time from a drive end time at which the display controller finishes driving in accordance with the update display data and drives the screen by using the read update display data. The display driver drives the self-luminous elements once or more at a timing when the update display data from the host controller to the display driver is not updated.

  • Patent number: 10367268
    Abstract: To provide a leaky-wave antenna that allows dual-polarization without limiting an emission range to either side. The antenna includes as an element unit (AE) a CRLH transmission line configured by multiply connecting CRLH unit cells (UC) in a periodic fashion between one ends and the other ends of two parallel lines (La, Lb). The respective unit cells (UC) have a left-handed series capacitor (C1, C2) on each of the two parallel lines (La, Lb) and have a left-handed parallel inductor (L1) between the two parallel lines (La, Lb). When power is fed between the two parallel lines (La, Lb), the two parallel lines (La, Lb) and the series capacitor (C1, C2) serve to emit a vertical polarization component, and the parallel inductor (L1) and a conductor between the two parallel lines (La, Lb) serve to emit a horizontal polarization component.
