A transparent display panel and a display panel. The transparent display panel includes a transparent display area. The transparent display area includes a plurality of first pixel units. Each of the first pixel units includes a plurality of first sub-pixels. Each of the first sub-pixels includes: a first electrode being light-transmitting; a first light-emitting structural block located on the first electrode; and a second electrode located on the first light-emitting structural block. At least one pixel driving circuit for driving the first sub-pixels to emit light is arranged outside of the transparent display area. A separating area is arranged between an area where the at least one pixel driving circuit is arranged and the transparent display area.

A vehicular trailer hitching assist system includes a rear backup camera disposed at a rear portion of a vehicle and a control disposed in the vehicle. A display device includes a video display screen operable to display video images for viewing by a driver of the vehicle. During a hitching maneuver event undertaken by the driver to hitch a trailer hitch of the vehicle to a trailer tongue of a trailer, and while the driver of the vehicle is maneuvering the vehicle to hitch the vehicle to the trailer, the control outputs video images derived from image data captured by the rear backup camera for display by the video display screen. At least one overlay overlays the displayed video images to guide the driver during the hitching maneuver. The at least one overlay aids in guiding connection of the trailer hitch of the vehicle to the trailer tongue of the trailer.

According to one embodiment, a color changing display includes a housing, a cover cooperatively coupled to the housing, a light panel, and a color display panel. The light panel and the color display panel are positioned between the housing and the cover. The light panel and the colored display panel are each selectively activated to operate in at least one of: a reflective mode, a transmissive mode, and a transflective mode.

Provided is a display device or a display system capable of displaying images along a curved surface, a display device or a display system capable of displaying images seamlessly in the form of a ring, or a display device or a display system that is suitable for increasing in size. The display device includes a display panel. The display panel includes a first part and a second part and is flexible. The first part can display images. The second part can transmit visible light. The display panel is curved so that the second part and the first part overlap with each other.

A display device includes a biometric information value acquiring portion, a comparing portion, and a subject state determining portion. The biometric information value acquiring portion subsequently acquires a subject's biometric information value. The comparing portion compares a first biometric information value that is subsequently acquired by the biometric information value acquiring portion with a second biometric information value which is different from the first biometric information value that is subsequently acquired by the biometric information value acquiring portion. The subject state determining portion determines that the user could get a certain improvement owing to the treatment on the user on the basis of a comparison result by the comparing portion.

A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a plurality of pixels. Each of the pixels has a reflection region for performing display in a reflective mode. The first substrate includes a pixel electrode provided in each of the pixels and a reflection layer positioned opposite to the liquid crystal layer with respect to the pixel electrode. The reflection layer has a first region positioned in each of the pixels and a second region positioned between any two pixels adjacent to each other. Voltages of an identical polarity are applied to the liquid crystal layer for any two pixels adjacent to each other in a row direction, for any two pixels adjacent to each other in a column direction, or for all the pixels.

A full-panel display with hybrid regional subpixel layouts is provided. The full-panel includes a display panel having a first region with an array of first subpixels of respective a first color, a second color, and a third color, and a second region with an array of second subpixels of respective the first color, the second color, and the third color. The array of first subpixels and the array of second subpixels are collectively configured to achieve a higher transmission rate in the first region to an accessory installed therein while keep a luminance ratio between the first subpixels unchanged from that between the second subpixels. Optionally, a number density and/or a unit subpixel area of the first subpixels of at least one color is smaller in the first region than that in the second region.

A switchable privacy display comprises a spatial light modulator with output polariser, a reflective polariser, a polar control liquid crystal retarder and an additional polariser. The electrodes of the polar control liquid crystal retarder are patterned with a mark. In wide angle and narrow angle operational modes, the electrodes of the liquid crystal retarder are driven such that the mark is not visible. In a mark display state, the electrodes are driven to provide visibility of the mark in reflected light to an off-axis observer.

A display panel, a display device, and a driving method thereof are provided. A light-reflecting layer is disposed under a light-emitting layer of the display panel. When the display panel is under strong light, the light-emitting layer does not work, and the light-reflecting layer reflects natural light to achieve a full-color display. When the display panel is in low light or darkness, the light-emitting layer works, and the light-reflecting layer reflects the light emitted by the light-emitting layer to reduce a working intensity of the light-emitting layer and achieves the full-color display, thereby improving service life and visual effect of organic light emitting diodes (OLEDs).

According to one embodiment, a reflective liquid crystal display apparatus includes a plurality of pixels and a temperature sensor. Further, the temperature sensor included in the reflective liquid crystal display apparatus is formed in one or more regions among a plurality of pixel regions partitioned into rows and columns. The reflective liquid crystal display apparatus can thereby measure the temperature of the pixels more accurately at real time compared with the case of using a temperature sensor attached onto a heatsink.
