Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
