Display panel module
View Patent ↗A display panel module including a display panel is provided, which defines a camera region. A backlight assembly disposed under the display panel, and a camera disposed under the backlight assembly; the backlight assembly includes a circuit board and light source units disposed on the circuit board at intervals; the circuit board in the backlight assembly is inclined downward and recessed at a position corresponding to the camera region to form a hollow funnel shape with a larger top opening and a smaller bottom opening; the top opening of the hollow funnel adjacent to the display panel is defined as a first opening, and the bottom opening adjacent to the camera is defined as a second opening; and light incident from outside can enter the camera through the first and second openings. The invention provides a display panel module, which provides a novel under-screen camera solution.
1. A display panel module, comprising:
a display panel comprising a display region and a camera region;
a backlight assembly disposed under the display panel; and
a camera disposed under the backlight assembly;
wherein the backlight assembly comprises a circuit board, and the circuit board comprises a horizontal plane parallel to the display panel and is defined with a funnel-shaped opening structure recessed toward the camera at a position corresponding to the camera region to allow light incident from outside of the display panel to enter the camera, and wherein the funnel-shaped opening structure comprises an inclined inner sidewall; and
wherein a plurality of light source units are arranged on the horizontal plane to provide light source required for the display region and arranged on the inclined inner sidewall to provide light source required for the camera region.
2. The display panel module according to claim 1 , wherein an inclination angle θ of the inclined inner sidewall relative to the horizontal plane ranges from 30 degrees to 70 degrees.
3. The display panel module according to claim 1 , wherein a vertical depth of the funnel-shape opening structure ranges from 50 μm to 600 μm.
4. The display panel module according to claim 1 , wherein one to ten rows of the plurality of light source units are arranged on the inclined inner sidewall of the funnel-shaped opening structure, and the plurality of light source units in each row are arranged in a circle.
5. The display panel module according to claim 4 , wherein the plurality of light source units provided on the inclined inner sidewall of the funnel-shaped opening structure are individually controlled for each row of the plurality of light source units.
6. The display panel module according to claim 4 , wherein the plurality of light source units provided on the inclined inner sidewall of the funnel-shaped opening structure are individually controlled for each light source unit.
7. The display panel module according to claim 1 , wherein a light-emitting angle of each of the plurality of light source units provided on the inclined inner sidewall of the circuit board ranges from 130 degrees to 170 degrees.
8. The display panel module according to claim 1 , wherein the plurality of light source units provided on the inclined inner sidewall of the circuit board are RGB three-color mini-LED light source units arranged in turn at intervals.
9. The display panel module according to claim 1 , wherein the display panel comprises an array substrate, a liquid crystal cell, and a CF substrate.
10. The display panel module according to claim 9 , wherein the CF substrate comprises a substrate glass, a photoresist layer, and a planarization layer which are sequentially disposed;
wherein the photoresist layer in the camera region comprises BM layer units arranged at intervals, and a transparent photoresist layer unit is arranged between the BM layer units; or alternatively, the planarization layer directly fills positions between the BM layer units.
