    摘要: A planar light-emitting device comprises a plurality of light-emitting units each including a lightguide plate and arranged adjacent to each other. Each lightguide plate has an upper surface as a light-exiting surface, a lower surface opposite to the upper surface, and a peripheral side surface extending between the peripheral edges of the upper surface and the lower surface, wherein a light-entrance surface is defined by a part of the peripheral side surface. The light-entrance surface has a first protruding portion extending from and along the light-entrance surface and an opposite surface opposing the light-entrance surface has a second protruding portions extending from and along the opposite surface. In each adjacently disposed pair of light-emitting units, the first protruding portion of the first light-emitting unit abuts against the second protruding portion of the second light-emitting unit. The light source is disposed underneath the abutting first and second protruding portions.

    摘要: A single light guide plate illuminates both first and second liquid crystal display panels opposed to each other, the second liquid crystal display panel having a larger display area than that of the first liquid crystal display panel. A light-absorbing sheet is provided between the light guide plate and the first liquid crystal display panel to absorb light from the light guide plate and has a light-transmitting part aligned with the first liquid crystal display panel in a direction from the light guide plate toward the first liquid crystal display panel to transmit light from the light guide plate to the first liquid crystal display panel. A reflective polarizing sheet is provided between the second liquid crystal display panel and the light guide plate. The light-absorbing sheet eliminates brightness unevenness on the second liquid crystal display panel, which would otherwise occur due to the influence of the first liquid crystal display panel, and the reflective polarizing sheet allows effective utilization of light from the light guide plate.

    摘要: The time required for analyzing a modulation accuracy of a modulated signal is reduced. A signal analyzing device which analyzes a signal to be measured including multiple frames each of which includes a preamble and a data symbol, includes frame acquisition units which acquire the frame from the signal to be measured, a symbol demodulation unit which demodulates the acquired frame according to symbol demodulation, and a modulation accuracy deriving unit which derives a modulation accuracy based on an output from the symbol demodulation unit, where the frame acquisition unit considers a position displaced by an integer multiple of the length of the frame from a start frame positioned at a start of the signal to be measured as a position of a subsequent frame positioned after the start frame, and acquires the subsequent frame.

    摘要: A planar light-emitting device allowing for high luminance uniformity has a plurality of light-emitting units (4), each including a lightguide plate (3) having a light-exiting surface, an opposite surface opposite to the light-exiting surface, a peripheral side surface extending between the respective peripheral edges of the light-exiting surface and the opposite surface, and a light-entrance surface (3a) defined by a part of the peripheral side surface. Each light-emitting unit further includes a light source (2) adjacently disposed to face the light-entrance surface to emit light into the lightguide plate through the light-entrance surface. The light-emitting units are arranged in a plurality of mutually adjacent rows with the light-exiting surfaces (3a) of their respective lightguide plates being substantially flush with each other. Adjacent rows of the light-emitting units are displaced relative to each other in the direction of the rows.
