A display device is disclosed. The display device includes a backlight module, a display panel, and a second viewing angle control layer. The backlight module includes: a back plate; a first light plate, where a hollowed region is defined in a center of the first light plate; a first viewing angle control layer disposed on the first light plate and including multiple first grid lines; and a rotating assembly, disposed in the hollowed region and configured to control the first viewing angle control layer to rotate in a direction parallel to a plane in which the display panel lies. The second viewing angle control layer is arranged on the first viewing angle control layer, and includes multiple second grid lines. An orthogonal projection of the second viewing angle control layer on the bottom plate overlaps an orthogonal projection of the first viewing angle control layer on the bottom plate.

Display device that prevents the vehicle-mounted display screen from affecting the main driver

A display controlling method, an in-vehicle display device, and a non-transitory computer-readable medium are provided in the present disclosure. The display controlling method is applied to the in-vehicle display device. The in-vehicle display device includes at least two display modules arranged in sequence along a first direction. The method includes controlling each user front-view display module to display with a first brightness; determining a second brightness corresponding to each user side-view display module based on a viewing angle corresponding to each user side-view display module, the second brightness being greater than the first brightness; and controlling each user side-view display module to display with a corresponding second brightness.

Display controlling method, in-vehicle display device, and computer-readable storage medium

Disclosed are a display apparatus and an in-vehicle display device. The display apparatus includes at least two display modules. The display modules are arranged in sequence along a first direction and includes at least one user front-view display module and at least one user side-view display module. A difference between a luminous angle of each user side-view display module and a viewing angle of the user side-view display module is within a preset difference range. The viewing angle is formed by a second direction and a normal direction of a corresponding display module, the second direction being from a point on the corresponding display module toward the user position; the luminous angle is formed by an emission direction and a normal direction of the corresponding display module; for each user side-view display module, an angle formed by the second direction and the emission direction is within a preset angle range.

Display apparatus and in-vehicle display device

The present disclosure provides a backlight driving circuit including a power supply module and a current adjustment module. The current adjustment module detects the brightness of the first light-emitting columns and/or the second light-emitting columns to obtain detection current, and compares the detection current with a mode switching current. The current adjustment module controls one first light-emitting column and one second light-emitting column to connect with one first wire simultaneously, or controls one first light-emitting column to connect with one second connecting wire and controls one second light-emitting column to connect with another second connecting wire.

Backlight driving circut, backlight module and display device

A display device and a backlight module are disclosed. The display device includes a backlight module and a liquid crystal display panel that are correspondingly arranged. The liquid crystal display panel includes a flat portion and at least one bent portion. One end of the bent portion is connected to an edge of the flat portion, and the other end is bent downward. The backlight module includes a light guide plate, an optical film, and a light supplementation structure. The optical film is arranged between the light guide plate and the liquid crystal display panel, and covers the light guide plate and the light supplementation structure. The light guide plate is disposed corresponding to the flat portion. The light supplementation structure is arranged between the light guide plate and the bent portion, and supplements light for the bent portion.
