There is provided an imaging element includes a photoelectric conversion unit that includes a first electrode, a photoelectric conversion layer, and a second electrode, in which the photoelectric conversion unit further includes a charge storage electrode that has an opposite region opposite to the first electrode via an insulating layer, and a transfer control electrode that is opposite to the first electrode and the charge storage electrode via the insulating layer, and the photoelectric conversion layer is disposed above at least the charge storage electrode via the insulating layer.

Compounds that are organic radicals that can have a dual function. The compounds can be fluorescent emitters that emit in the near-IR. The compounds can also facilitate reverse intersystem crossing (RISC) to convert triplet excitons in an OLED to singlet excited states to maximize utilization of generated excitons in the OLED and approach 100% internal quantum efficiency.

The present invention relates to a compound of the formula (1), to the use of the compound in an electronic device, and to an electronic device comprising a compound of the formula (1). The present invention furthermore relates to a formulation comprising one or more compounds of the formula (1).

The present disclosure provides an optical adhesive layer, a stretchable display device and a preparing method for the optical adhesive layer. The optical adhesive layer includes: an edge region enclosing a hollow portion; a plurality of block regions distributed in the hollow portion along a first direction and a second direction; and connection ribs connecting the block regions to the edge region, wherein the connection ribs are distributed in the hollow portion in a net form, and the connection ribs include a plurality of first ribs, second ribs, and third ribs connecting the block regions with the first and second ribs.

Provided are: an organic electronic element comprising an anode, a cathode, and an organic material layer between the anode and the cathode; and an electronic device comprising the organic electronic element, wherein the organic material layer comprises compounds represented by Formula 1 and Formula 1, respectively, and thus can lower the driving voltage of the organic electronic element and improve the luminosity and lifespan thereof.

A solar cell system and a flexible solar panel are disclosed herein. The solar cell system includes a glass housing, a set of rows of solar cells each defining a front side and a rear side and arranged within the glass housing. The solar cell system can also include a reflective element disposed in the glass housing and facing the rear side of the set of rows of solar cells and a first terminal coupled to a first end of the set of rows of solar cells, traversing through and sealed against the first end of the glass housing. The solar cell system can be configured with other solar cell systems into the flexible solar panel that is deployable in a wide range of potential applications.

An inward foldable screen electronic device having a flexible display that includes an encapsulation layer, a light-emitting layer, a substrate, a base film, and a support sheet that are sequentially stacked. An interface exists between the encapsulation layer and the light-emitting layer, and the support sheet has a complete surface. The encapsulation layer and the light-emitting layer of the flexible display are not prone to lift off from each other.

An organic light-emitting diode (OLED) display panel, a manufacturing method thereof, and an OLED display device are provided. At least one of a substrate or a backplate in the OLED display panel has a reduced thickness, thereby increasing light transmittance of an electronic element area. Furthermore, an area where a camera lens is disposed can display normally and an under-display camera can be realized without defining a hole. Therefore, a screen-to-body ratio is increased, and a technical problem is solved: in conventional OLED display panels, the hole needs to be defined on the area where the camera lens is disposed, leading to a display effect being affected.

The present invention relates to a compound of formula (I) for use in organic electronic devices, a composition comprising a compound of formula (IV) and at least one compound of formula (IVa) to (IVd), an organic semiconductor layer comprising the compound or composition, an organic electronic device comprising the organic semiconductor layer, and a display device comprising the organic electronic device.

A display apparatus having a noncontact input function is provided. The display apparatus has a first function of detecting, with a light-receiving device, light irradiated from a light source outside a display portion and blocked by a pointing object to recognize the position pointed by the pointing object, and a second function of detecting, with the light-receiving device, light irradiated from a light source inside or outside the display portion and reflected by the pointing object to recognize the position pointed by the pointing object. The display apparatus can operate by switching the first function and the second function in accordance with the intensity of the light irradiated from the light source outside the display portion.
