An electronic device including a flexible display panel is provided. The electronic device includes a display panel, a first component, a movable module, and a housing. The housing includes a first movable portion, a second component, and a third component. The third component includes a first space where the first component is stored. The display panel includes a flexible display portion. The display portion includes a first region, a second region, and a third region. The first region is fixed to the second component. The second region is fixed to the first component stored in the third component. The movable module has a function of holding a first angle that is formed between the second component and the third component by the first movable portion. The third region positioned between the first region and the second region has a function of forming a curved surface according to the first angle. The first component slides in the first space according to the first angle.

A display device includes a frame module, a display panel, a backlight module, a rear case and a control module. The frame module includes a back plate, a frame and a fixing column. The back plate has a first surface and a second surface opposite to the first surface and a hole extending from the first surface to the second surface. The fixing column is protrudingly disposed on the frame and is coupled to the hole. The fixing column includes a pressing portion and a connecting portion connecting the frame and the pressing portion. The connecting portion is disposed in the hole, and the frame presses against the first surface, and the pressing portion presses against the second surface. The backlight module is disposed between the back plate and the display panel. The control module is disposed between the rear case and the frame module.

To improve brightness of image information visually recognized by a user while using plastic for a light guide plate. An image display element includes: a substrate made of resin; an incident diffraction grating that diffracts incident light; and an exit diffraction grating that emits the light, the incident diffraction grating being formed on a first surface of the substrate, the exit diffraction grating being formed on a second surface on a side opposite to the first surface of the substrate, and the exit diffraction grating being formed on one surface.

A digital video system at a cinema includes a plurality of personal cinema experience area seats each with a display screen for viewing at least one of a programs playing the cinema or steamtable to the cinema. Each seat is positioned at a selected area of the cinema. One or more speakers are provided at each seat. A DCI compliant cinema player is provided for each seat of the plurality of personal cinema experience area seat.

Imaging and display system includes: a display; an optical system including a first mirror and a second mirror; a housing; a light-transmissive cover transparent to light and disposed to cover at least part of an opening of the housing; and a driver monitoring camera supported by a supporting body connected outside of the housing. First light emitted from the display passes through the light-transmissive cover via the optical system, and is reflected by a windshield toward a direction of the user. The driver monitoring camera captures an image of a driver shown on the light-transmissive cover by second light from a direction of the driver reflected by the windshield toward a direction of the light-transmissive cover.

A display device having a display region to be viewed through a lens, the display device comprising: a substrate; and the display region in which the substrate is provided with a plurality of pixels, a plurality of scan lines extending in a first direction, and a plurality of signal lines extending in a second direction, wherein the first direction is non-parallel and non-orthogonal to a direction orthogonal to the second direction.

A head mounted display device includes: a mounting state sensor (for example, a sensor) in which a sensor value changes according to a mounting state; a mounting state determination unit for determining a mounting state according to an output of the mounting state sensor; a storage unit for storing a content to be displayed; a content control unit for changing the content stored in the storage unit; and a display unit for displaying the content stored in the storage unit. The content control unit changes the content according to the mounting state output by the mounting state determination unit.

A display device includes first and second support members arranged along a first direction, a joint part therebetween, a hinge member adjacent to facing sides of the first and second support members that extends in a second direction crossing the first direction, and that includes two rotation axes, and a flexible display module on the first and second support members and the joint part. The joint part includes a first joint unit that extends in the second direction and a plurality of second joint units arranged in the first direction, where the first joint unit is interposed between the plurality of second joint units. The second joint units extend in the second direction, and each of the second joint units has recesses between side and top surfaces thereof and that extend in the second direction.
