A heterocyclic compound containing heteroatom substituted fluorene and an optoelectronic device are provided. The heterocyclic compound includes a structure in Formula I: where Y is selected from O or S; at least one of X, X, X, X, X, X, Xand Xis a N atom, and rest are CR; L, L, and Lare independently selected from single bond, substituted or unsubstituted aromatic groups; Arand Arare independently selected from substituted or unsubstituted aromatic groups or heteroaryl groups; Ris selected from a hydrogen atom, a deuterium atom, or an aromatic group or a heteroaryl group condensed with adjacent groups; and Ris selected from a hydrogen atom, a deuterium atom, a substituted or unsubstituted C1-C5 alkyl group, a halogen, a cyano group, or an amino group.

Heterocyclic compound containing heteroatom substituted fluorene and optoelectronic device

Display panel and display device are provided. The display panel includes a display area and a non-display area. The non-display area includes a bending area and a first area. The first area is located on a side of the bending area away from the display area. The display panel comprises a substrate, a driving array layer disposed on a side of the substrate, and a touch function layer disposed on a side of the driving array layer away from the substrate. The driving array layer includes a first metal layer. In the first area, the first metal layer includes a plurality of first touch signal lines and a plurality of first fixed potential signal lines. At least one first fixed potential signal line of the plurality of first fixed potential signal lines is disposed between two adjacent first touch signal lines of the plurality of first touch signal lines.

Display panel and display device

Provided are an organic compound, an electroluminescent material, and a use thereof. The organic compound has a structure represented by Formula I and is a carbazole olefin-like compound which is beneficial for improving the amorphous performance, thermal stability, and glass transition temperature of the material. The organic compound has appropriate HOMO energy level and LUMO energy level and a relatively high triplet energy level and can inhabit the transfer of triplet energy from a guest back to a host and reduce a driving voltage of a device. The organic compound, as a host material, has a relatively high carrier transport rate and balanced carrier transport performance, so as to facilitate the balance of hole and electron currents in the device, obtain a wider carrier recombination region, significantly improve light emitting efficiency and external quantum efficiency of the device, and reduce a turn-on voltage and power consumption of the device.

Organic compound, electroluminescent material, and use thereof

Provided are a display device and a control method thereof. The polarizer is disposed on a light-emitting side of the display panel, and the imaging module is disposed on a non-light-emitting side of the display panel. The display panel includes a first display region, and in a direction perpendicular to the polarizer, the polarizer covers the first display region and the imaging module at least partially overlaps the first display region. The polarizer includes a polarized state and an unpolarized state, and a light transmittance of the polarizer in the unpolarized state is greater than a light transmittance in the polarized state. The first reaction light emitting unit emits a first reaction light to the first display region. The polarizer includes a light sensitive structure, and the light sensitive structure adjusts the polarizer from the polarized state to the unpolarized state under the action of the first reaction light.
