The present disclosure provides a display substrate and a display device, belonging to the field of display technology, which can solve the problem that a splicing gap between existing adjacent display substrates of a spliced screen is relatively wide, and a narrow-bezel display cannot be realized. The display substrate of the present disclosure has a display area and a non-display area surrounding the display area; the display substrate includes a base and a plurality of pixel units located on the base and arranged in the display area; each of the pixel units includes a pixel circuit. The display substrate further includes: a light detection circuit located on the base and arranged in the non-display area; where the light detection circuit is configured to detect brightness of ambient light.

The present disclosure provides a curved-surface vehicle-mounted display module, a vehicle-mounted display device and a vehicle. The curved-surface vehicle-mounted display module includes a back plate, a backlight assembly and a liquid crystal panel. The back plate is configured to support the backlight assembly and the liquid crystal panel. The backlight assembly includes a flexible substrate and LEDs. The flexible substrate includes at least one backlight block, each backlight block is provided with a plurality of LEDs, and a distance between two adjacent LEDs is a predefined value.

A one-piece display has a main display area at least partly viewable from one point of observation, and a secondary display area arranged so as to not be viewable from that point of observation. The main display area and the secondary display area are arranged relative to one another in such a way that the secondary display area is reflected in the main display area to produce a virtual display plane that is viewable from the point of observation.

A trim element having an outer surface that is at least partially translucent, the outer surface defining a main display surface and a peripheral display surface, the peripheral display surface extending around at least a portion of the main display surface, a screen of a display device extending opposite the main display surface. The trim member includes an illumination device having a luminous sheet extending opposite the main display surface and the peripheral display surface so as to emit at least a first luminous signal onto the screen and at least a second luminous signal illuminating at least a portion of the peripheral display surface when the luminous sheet is activated.

A trim element having a display area defined by a display device, and an edge piece that includes a peripheral area extending around at least part of the display area, the peripheral area being at least partly translucent, the display area and the peripheral area forming at least a part of an outer surface of the trim element. The trim element further includes an illumination device arranged to illuminate the display device to display images on the display area. The illumination device has a luminous sheet extending at least facing the display area and the peripheral area of the edge piece.

An instrument includes: a liquid-crystal display device including a display element and light sources provided along one side surface extending in the Y direction of the element; a first case having a reference positioning pin, and other positioning pins; and a second case having a reference hole into which the reference positioning pin is inserted, other holes into which the other positioning pins are inserted, a first region in which a first pointer-type instrument is provided, a second region in which a second pointer-type instrument is provided, and a third region in which the liquid crystal display device is provided between the first region and the second region. The third region has an edge corresponding to the position where the side surface 4a is disposed, and the reference hole is provided on the edge side with respect to the center of the third region in the X direction.

A display device includes a transparent display screen element, which has a front side and a rear side opposite to the front side, and a polarizing element arranged flatly on the rear side of the transparent display screen element. The polarizing element is to attenuate light output by at least one lighting element of the transparent display screen element. A motor vehicle may have such a display device, in particular where the display device may be arranged freestanding at or on an interior trim element of the motor vehicle.

A charging device for an electric vehicle includes a network connection unit, a display light-panel, and a processor. The network connection unit is coupled to a server through a network and receives an indication of an operation of a charging procedure performed by a user device corresponding to the electric vehicle via the network. The display light-panel has an optical light-guiding component and a backlight module, wherein the optical light-guiding component has a fixed pattern printed thereon and the backlight module includes light sources, and the optical light-guiding component and the light sources are respectively disposed to operate the display light-panel in at least one illumination mode. The processor respectively changes the illumination mode of the display light-panel in response to the received indication, such that the display light-panel changes the light sources to generate an interaction display effect corresponding to the operation of the charging procedure.

A switchable backlight for a switchable privacy display apparatus comprises a collimated waveguide and an optical turning film comprising first and second arrays of elongate prismatic elements. High image luminance and image visibility is provided for off-axis viewers in a public mode of operation while in a privacy mode of operation visual security level above a perceived privacy threshold may be achieved for off-axis snoopers.

A flip dot display apparatus for a vehicle includes a plurality of flip dot units disposed in a front grill disposed at a front bumper of the vehicle, and configured to transfer either one or both of notice information on a state of the vehicle and notice information on driving of the vehicle to an oncoming vehicle or a pedestrian. Each flip dot unit among the plurality of flip dot units includes: a housing having an opening formed on one side thereof and a space formed therein; and a flip disk rotatably installed in the housing and configured to open or close the opening.
