A display unit of the disclosure includes a display panel and a light-distribution adjustment sheet. The light-distribution adjustment sheet is provided on the display panel, and includes a protrusion that protrudes toward the display panel. The protrusion includes a first region including a curved surface, and a second region including a flat surface.

Light-distribution adjustment sheet and display unit

An optical unit includes a ball lens and a light source. The ball lens condenses light and outputs the condensed light. The light source has a light emitting surface and the light source outputs light toward the ball lens. The light emitting surface is located closer to the ball lens than a focal position of the ball lens.

Optical unit, illumination apparatus, display, and optical communication apparatus

A backlight unit of the present disclosure includes: a backlight including a plurality of light-emitting devices that are allowed to emit light at mutually different timings and include a first light-emitting device and a second light-emitting device; and a controller that controls a light emission operation of the backlight to cause the first light-emitting device and the second light-emitting device to emit light with mutually different average light emission intensities in a first sub-frame period of a plurality of sub-frame periods provided corresponding to a frame period.

Backlight system, display apparatus, and light emission control method

There is provided an optical member that achieves a desired light distribution characteristic while having a simple configuration. The optical member includes a first transparent optical sheet and a second transparent optical sheet that are superimposed on each other in a first axial direction. The first transparent optical sheet includes a structure in which a first region and a second region are alternately disposed in a second axial direction. The second transparent optical sheet includes a structure in which a third region and a fourth region are alternately disposed in a third axial direction. An angle formed by the third axial direction with respect to the second axial direction is equal to or greater than 0&#xb0; and less than 45&#xb0;.

Optical member, light-emitting device, display, and illuminator

Disclosed herein is a light emitting element driving circuit including: a capacitive element; a current limiting section limiting a charging current for the capacitive element; a first constant current source stabilizing a discharging current supplied from the capacitive element to a light emitting element; and a switch controlling ON and OFF in supplying the discharging current to the light emitting element. The capacitive element is charged with electricity from the power source circuit in the preceding stage through the current limiting section. Also, the electric charges in the capacitive element are discharged in the form of a given discharging current for the discharging time period, and the light emitting element emits light in accordance with the given discharging current. In this case, the charging current for the capacitive element is limited by the current limiting section in such a way that the current value thereof becomes small.

Light emitting element driving circuit, light emitting device, display device, and light emission controlling method

Provided is an illumination unit capable of utilizing back light. Also provided are a display and an electronic apparatus each including this illumination unit. A display includes a display panel, and an illumination unit configured to illuminate the display panel. The illumination unit includes a light-guiding plate, a diffusion modulation device, and a reflection modulation device in this order, from the display panel side. The light-guiding plate has a light source on a side face thereof. The diffusion modulation device is capable of performing modulation between a first state of diffusing light from the light source, and a second state of allowing incident light from a back face side to pass to a front face side. The reflection modulation device is capable of performing modulation between a third state of reflecting transmitted diffused light of the diffusion modulation device to a front face side, and a fourth state of allowing incident light from a back face side to the front face side.

Illumination unit, display, and electronic apparatus

A display unit includes: an image display panel; a backlight section disposed on a back surface of the image display panel, and including a light guide member and a polymer dispersed liquid crystal panel; a light source emitting light, the light being allowed to enter the light guide member of the backlight section; a polymer dispersed liquid crystal panel drive section driving the polymer dispersed liquid crystal panel of the backlight section in synchronization with writing of an image displayed on the image display panel to control a location that scatters light incident on the light guide member on the polymer dispersed liquid crystal panel; and a light source drive section allowing the light source to blink in synchronization with a period in which light is scattered by the polymer dispersed liquid crystal panel.

Display unit, displaying method, and recording medium

A light source unit is used in a multiply combined manner, and includes a light source element having a substrate and one or more light emitting elements disposed on the substrate. The light source unit is configured such that when a plurality of the light source units are arranged in cascade, the light source element in the light source unit comes to in electric connection with another light source element in an adjacent light source unit. Thereby, the plurality of light source units may emit light at the same time. Thus, the structure similar to rod-shaped light source such as CCFL is achieved.

Light source unit, light source device, and display apparatus

A display device includes: a light source section having multiple light sources to emit light in illumination colors including three primary colors of light; a display section for displaying an image in monochrome color by modulating the light emitted from the light source section; and a display control section for driving the light source section and the display section in a field sequential system. The display control section includes a determining section for determining a degree of white or a degree of complementary color of the light sources on the basis of an amount of lighting of each of the illumination colors of the light sources, a setting section for setting white components or complementary-color components of a color determined by a mixing ratio of the illumination colors, and an allocating section for allocating the set white components or the complementary-color components to the fields.

Display device, drive method therefor, and electronic apparatus
