A display device includes a display panel; a temperature information acquisition unit that acquires peripheral temperature information on a periphery of the display panel; and a control unit that controls drive current to be supplied to the display panel. The control unit controls the drive current to be supplied to the display panel to a first drive current value when a peripheral temperature indicated by the peripheral temperature information is within a prescribed temperature range, and a second drive current value lower than the first drive current value when the peripheral temperature indicated by the peripheral temperature information is higher than the prescribed temperature range.

Display device, display control method, and non-transitory computer-readable recording medium

An illumination device includes: a light source; an optical sheet having a rectangular shape and imparting an optical effect on light from the light source; a display component having a rectangular shape and being provided on the optical sheet; and a frame member having a frame shape surrounding the optical sheet and, on at least one edge of the optical sheet, selectively and directly or indirectly pressing an area that is located relatively more towards a center of the edge of the optical sheet than both sides of the edge so as to secure said area to the display component.

Illumination device, display device, and television receiving device

A buffer member () which abuts on a front surface side of a panel periphery of a display panel is made of a material having a light shielding property and has a portion, which extends over substantially the whole length of a side, along at least one of the respective sides of a rectangular display region. A buffer member () which abuts on a back surface side thereof has a portion, which extends over a range of a side except both the end portions thereof, along at least one of the respective sides of the rectangular shape. Accordingly, deformation of the display panel is reduced and it is possible to prevent light leakage in a peripheral portion of the display screen.

Display apparatus

A liquid crystal display device () is provided with the following: an LED (); a liquid crystal panel (); a light guide plate () disposed so as to overlap the liquid crystal panel (); an optical member () disposed between the liquid crystal panel () and the light guide plate (); a holding member (HM) having a frame () and a chassis () for holding in a sandwiched manner the liquid crystal panel (), the optical member () and the light guide plate (); a first object of positioning determination unit () disposed at the edge of the light guide plate (); a positioning determination unit () disposed on the frame () and for determining the position of the light guide plate () in a direction following the plate surface by causing uneven engagement of the light guide plate with respect to the first object of positioning determination unit (); and a light-shielding sheet () for blocking direct incidence of light from the first object of positioning determination unit () on the liquid crystal panel () by covering at least a portion of a gap (C) formed between the positioning determination unit () and the first object of positioning determination unit () and by being provided between the light guide plate () and the liquid crystal panel ().

Image display device and television reception device

A liquid crystal display device includes: a display control unit configured to cause the liquid crystal panel to display a right eye image and a left eye image in an alternating manner; and a polarity control unit configured to cause the polarity of the drive voltage for the liquid crystal panel to be reversed. The polarity control unit causes the polarity of the drive voltage to be reversed such that, in one cycle including a number of display frames for right and left eye images, the number being a multiple of 8, the combination of polarities for image display in one pair of display frames composed of right and left eye images is one of four combinations and a number of occurrences of each of the four combinations is equal.
