  • Publication number: 20220124217
    Abstract: An electronic apparatus includes circuitry that selects at least one destination information set for transmission from a plurality of address books each holding a plurality of destination information sets. In response to reception of a notification of a change in one of the plurality of address books, the circuitry determines whether the selected at least one destination information set includes a destination information set selected from the one of the plurality of address books corresponding to the notification of the change. Based on a determination that the selected at least one destination information set includes the destination information set selected from the one of the plurality of address books corresponding to the notification of the change, the circuitry resets the selected at least one destination information set.

  • Publication number: 20210033901
    Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.
