摘要： In a photosensor in the pixel region of an active matrix substrate, the potential of a storage node is read out to output wiring as sensor circuit output, the potential of the storage node having changed in accordance with the amount of light received by a photodetection element in a sensing period, the sensing period being from when a reset signal (RS) is supplied until when a readout signal (RW) is supplied. A sensor startup period whose length is greater than or equal to the length of the sensing period is provided after a sensor data unnecessary period in which the sensor circuit output is not necessary, and furthermore before a valid sensor data period in which the sensor circuit output is necessary, and the sensor circuit output is read out in the valid sensor data period from the photosensor to which the reset signal was applied in the sensor startup period.

摘要： In a liquid crystal display including a liquid crystal display panel formed by sandwiching a liquid crystal layer between an active matrix substrate and an opposed substrate, and a backlight that illuminates the liquid crystal display panel from a side of the active matrix substrate, a first optical sensor and a second optical sensor are disposed in a peripheral region on a glass substrate of the active matrix substrate. The first optical sensor is formed so that light external to the liquid crystal display and light propagating inside the active matrix substrate enter the first optical sensor. The second optical sensor is formed so that only light propagating inside the active matrix substrate enters the second optical sensor. Also, the second optical sensor is shielded from the external light. For example, a light-shielding film is formed on an upper surface of the second optical sensor.

摘要： A light shield (204) for blocking light traveling toward a PIN photodiode (413) from a glass substrate (314) side is formed of a conductive material, and a reference electric potential (Vr−nVoc) equal to that of a cathode of the PIN photodiode (413) is applied to the light shield (204) from a power supply circuit (266). Thus, inductive noise for a photoelectric conversion device used for an ambient light sensor is further reduced in a display device.

摘要： An optical display system includes: a light source; a display panel including multiple pixel regions, each of which can modulate light; and an optical shifter, which is disposed so as to receive an outgoing light ray of the display panel and optically shift an image on the display panel on a frame-by-frame basis. The optical shifter includes a first element for selectively changing the polarization direction of the outgoing light ray of the display panel, and a second element, which exhibits one of multiple different refractive indices according to the polarization direction of an incoming light ray. A polarization corrector, which changes the polarization direction of the outgoing light ray of the display panel into a direction that is either parallel to, or perpendicular to, a direction in which the image is shifted, is provided between the display panel and the optical shifter.
