Abstract
The present disclosure provides a display panel, a manufacturing method thereof, and a display device. The display panel includes: a backlight module configured to provide a light source; a cover plate on a light-emitting side of the backlight module; a display module between the cover plate and the backlight module; and a photosensitive device configured to sense ambient light. The photosensitive device is between the cover plate and the backlight module, and at an edge of the cover plate.
Claims17
A display panel comprising:
- a backlight module configured to provide a light source;
- a cover plate on a light-emitting side of the backlight module;
- a display module between the cover plate and the backlight module, wherein the display module comprises an array substrate and an optical film layer on a side of the array substrate facing the cover plate, and a first edge of the array substrate protrudes relative to the optical film layer;
- a photosensitive device configured to sense ambient light, wherein the photosensitive device is between the cover plate and the backlight module and at an edge of the cover plate, and the photosensitive device is at a side of the display panel where the first edge of the array substrate is located, and is directly on a portion of the array substrate protruding relative to the optical film layer;
- and
- a first circuit board bent from a side of the backlight module facing the cover plate to a side of the backlight module facing away from the cover plate, such that a first end of the first circuit board is coupled to a second edge of the array substrate, and a second end of the first circuit board is coupled to a surface of the backlight module facing away from the cover plate, and the second edge of the array substrate is opposite to the first edge of the array substrate and is not provided with the photosensitive device,
- wherein the second edge of the array substrate protrudes relative to the optical film layer, and the display panel further comprises a supporting structure, which is on a side of the display panel where the second edge of the array substrate is located, and is directly on a portion of the array substrate protruding relative to the optical film layer.

A method for manufacturing a display panel, comprising:
- providing a backlight module, wherein the backlight module is configured to provide a light source;
- providing a display module and a photosensitive device on a light-emitting side of the backlight module, wherein the photosensitive device is configured to sense ambient light, wherein the display module comprises an array substrate and an optical film layer on a side of the array substrate facing the cover plate, a first edge of the array substrate protrudes relative to the optical film layer, and the photosensitive device is at a side of the display panel where the first edge of the array substrate is located, and is directly on a portion of the array substrate protruding relative to the optical film layer;
- providing a cover plate on a side of the display module and the photosensitive device facing away from the backlight module, wherein an orthographic projection of the photosensitive device on the cover plate is within an orthographic projection of the backlight module on the cover plate;
- and
- providing a first circuit board bent from a side of the backlight module facing the cover plate to a side of the backlight module facing away from the cover plate, such that a first end of the first circuit board is coupled to a second edge of the array substrate, and a second end of the first circuit board is coupled to a surface of the backlight module facing away from the cover plate, and the second edge of the array substrate is opposite to the first edge of the array substrate and is not provided with the photosensitive device,
- wherein the second edge of the array substrate protrudes relative to the optical film layer, and the method further comprises providing a supporting structure on a side of the display panel where the second edge of the array substrate is located, and directly on a portion of the array substrate protruding relative to the optical film layer.
