  • Publication number: 20240122818
    Abstract: The present invention relates to light-scattering silica particles having a light scattering property, the light-scattering silica particles including: a plurality of hollow portions each having a closed pore structure inside the particle, in which the light-scattering silica particles have a volume-based cumulative 50% particle diameter of 1 ?m to 500 ?m and an average circularity of 0.80 or more, and in use of the light-scattering silica particles, a reflectance A of a water cake containing 20 mg/cm2 of silica per measurement cross-sectional area at an ultraviolet wavelength of 310 nm is 30% or more.

  • Patent number: 11120732
    Abstract: A display driver includes: a receiver configured to receive image data of each line of a display panel from an external device; a line latch circuit having a line latch configured to latch the image data of each line received by the receiver in response to a strobe signal; a driving circuit section which drives the display panel in response to the image data latched by the line latch; and a timing controller configured to generate the strobe signal. The receiver is configured to detect occurrence of transmission error in data transmission about each line. The timing controller is configured to generate the strobe signal in response to a detection result of the occurrence of transmission error.
