In the backlight module, alight modulation surface of the annular light modulation portion is connected to an end of a corresponding light incident surface away from a physical center, and in a direction from the physical center to the annular light modulation portion, a degree of an acute angle between the light modulation surface and the light incident surface is sequentially increased; or, a light modulation surface corresponding to the annular light modulation portion is connected to an end of a corresponding light incident surface near the physical center, and in the direction from the physical center to the annular light modulation portion, the degree of the acute angle between the light modulation surface and the light incident surface is sequentially increased.

Backlight module including angular deflection film and display device including the same

A display panel is disclosed and comprising a display substrate, a light sensor, and a light absorption layer; the light sensor is formed in the display substrate and configured to sense ambient light; the light absorption layer is disposed on the display substrate and overlapped with the light sensor; and the material of the light absorption layer comprises at least one of an infrared light absorbent and an ultraviolet light absorbent.

Display panel

A backlight module and a display device are provided. The backlight module includes a light-emitting substrate. The light-emitting substrate includes a substrate, an array layer disposed on the substrate and including a plurality of photosensitive units and switch units, and a plurality of light-emitting chips disposed on a side of the array layer away from the substrate and staggered from the photosensitive units. The light-emitting chips are electrically connected to at least one of the switch units.

Backlight module and display device

A display panel and a display device are provided. A light-controlling component configured to adjust a signal transmitter is disposed on a light-emitting surface of the signal transmitter of the display panel, thereby allowing modulated light, emitted from the signal transmitter disposed at a predetermined included angle with respect to a bottom surface of a cover plate, to be totally reflected between a top surface and the bottom surface of the cover plate. Total reflection is interrupted at a position where a user's finger touches. Light is received and recognized by a plurality of light sensors on a sensor array after entering the display panel, thereby realizing under-display fingerprint recognition in a large area.

Display panel and display device

A display module is provided. The display module includes a cover plate and a reflection layer. A touch light source is disposed in an edge region of the display module. A first grating is disposed on a side of the cover plate facing toward the touch light source. The first grating is obliquely disposed to the cover plate. After light emitted from the touch light source passes through the first grating, the light enters into the cover plate and is total reflection. Obtaining information of a to-be-recognized terminal from an entire surface of the display module can be realized after the total reflection is destroyed when the to-be-recognized terminal touches a surface of the cover plate.

Display module

A backlight module and a display device are provided. The backlight module includes a first light-emitting component and a second light-emitting component. The first light-emitting component includes a regular light guide plate, and an angle between a light emitted by the first light-emitting component and a first direction is less than or equal to a first preset angle, and the first direction is perpendicular to the first direction. The second light-emitting component includes a collimated light guide plate, an angle between a light emitted by the second light-emitting component and the first direction is less than or equal to a second preset angle, and the second preset angle is less than the first preset angle.

Backlight module and display device including privacy-protection display mode

A display panel and a manufacturing method thereof are provided by the present application. The display panel includes a first liquid crystal cell, a second liquid crystal cell, and a flexible circuit board. The first liquid crystal cell includes a first epitaxial portion. The first epitaxial portion includes a plurality of first bonding terminals. The second liquid crystal cell includes a second epitaxial portion. The second epitaxial portion includes a plurality of second bonding terminals. And the second binding terminals and the first binding terminals are located on a same side. The flexible circuit board is electrically connected with the first binding terminals and the second binding terminals.

Display panel and manufacturing method thereof

A display panel and an electronic device are provided. The electronic device includes the display panel. The display panel includes a display panel main body, a protective layer, a light source module, and a light sensor. Outgoing light emitted by the light source module can be totally reflected in the protective layer. When a finger touches an area of the protective layer corresponding to a display area, light emitted to the finger can be reflected to light sensor. As such, a range of under-screen fingerprint recognition can be increased.
