CROSS REFERENCE TO RELATED APPLICATIONS

This patent application is a National Stage Entry of PCT/CN2019/081196 filed on Apr. 3, 2019, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

BACKGROUND

Embodiments of the present disclosure relate to a field of display technology, and in particular, to a display panel and a display device.

Mobile terminals such as mobile phones typically include a display panel and an imaging element. With the progress of society and the continuous improvement of living standards, people's requirements for mobile terminals are also increasing. The screen ratio of a mobile terminal (the ratio of the area of the display region of the display panel to the area of the surface of the entire mobile terminal) is constantly increasing, and it is moving towards full screen display.

BRIEF DESCRIPTION

An aspect of the present disclosure provides a display panel including a plurality of wirings extending parallel to a display surface of the display panel, and a plurality of light shielding portions extending parallel to the display surface, wherein projections of at least two wirings of the plurality of wirings with parallel extending directions on the display surface are within a projection of a same light shielding portion on the display surface, wherein at least a portion of each light-shielding portion has a curved profile along the extending direction.

In some embodiments, the at least two wirings include a gate line or a data line.

In some embodiments, the curved profile has a wave shape along the extending direction.

In some embodiments, a curvature radius of each wave unit of the wave shape at a peak is in a range of approximately 5-10 μm.

In some embodiments, a width of each wave unit of the wave shape is in a range of approximately 4-7 μm.

In some embodiments, each light shielding portion has a symmetrical shape with respect to an axis parallel to the extending direction.

In some embodiments, a peak of the wave unit of one of two adjacent light shielding portions with parallel extending directions is not aligned with a peak of the wave unit of the other one of the two adjacent light shielding portions in a direction perpendicular to the extending directions.

In some embodiments, a peak of the wave unit of one of the two adjacent light shielding portions with parallel extending directions is aligned with a trough of the wave unit of the other one of the two adjacent light shielding portions in a direction perpendicular to the extending directions.

In some embodiments, a distance between two adjacent light shielding portions with parallel extending directions is greater than approximately 80 μm.

In some embodiments, a distance between two adjacent light shielding portions with parallel extending directions is greater than approximately 120 μm.

In some embodiments, the display panel includes a first area and a second area, wherein a transmittance of the first area is greater than a transmittance of the second area, and wherein the light shielding portion is disposed only in the first area.

In some embodiments, a pixel density of the first area is less than a pixel density of the second area.

In some embodiments, the at least two wirings include a first wiring and a second wiring extending in a first direction, and the second wiring is more adjacent to the first wiring in the first area in a second direction perpendicular to the first direction than other wirings extending in the first direction.

In some embodiments, one of the first wiring and the second wiring is configured to provide a signal to a same pixel of the first area.

In some embodiments, the at least two wirings include a third wiring and a fourth wiring extending in the second direction, and the fourth wiring is more adjacent to the third wiring in the first area in a first direction than other wirings extending in the second direction.

In some embodiments, one of the third wiring and the fourth wiring is configured to provide a signal to a same pixel of the first area.

In some embodiments, the first wiring and the second wiring are one of a data line and a gate line, and the third wiring and the fourth wiring are the other one of the data line and the gate line.

In some embodiments, the display panel further includes an additional layer located in the second area and extending to the first area, wherein a projection of an edge of the additional layer close to the first area on the display surface is within a projection of the light shielding portion on the display surface.

In some embodiments, the display panel further includes a first substrate, and a thin film transistor located on the first substrate, wherein the light shielding portion is located between the thin film transistor and the first substrate, and a projection of the thin film transistor on the display surface is within a projection of the light shielding portion on the display surface.

In some embodiments, the display panel further includes a buffer layer on the light shielding portion, a planarization layer on the thin film transistor, an electrode layer on the planarization layer, a pixel-defining layer having an opening area on the electrode layer, and a light-emitting material layer in the opening area of the pixel-defining layer, wherein the additional layer includes at least one of the planarization layer and the pixel-defining layer.

Another aspect of the present disclosure provides a display device including the display panel according to any one of one or more embodiments of the present disclosure.

In some embodiments, the display device further includes an imaging element located on a side of the display panel away from the display surface, wherein the display panel has a first area and a second area, and a transmittance of the first area is greater than a transmittance of the second area, the light shielding portion is provided only in the first area, and an orthographic projection of the imaging element on the display panel is within the first area.

Further aspects and areas of applicability will become apparent from the description provided herein. It should be understood that various aspects of this disclosure may be implemented individually or in combination with one or more other aspects. It should also be understood that the description and specific examples herein are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
