Abstract: A display device is provided, including a backlight module and a liquid crystal display module. The backlight module is provided with a through hole. The liquid crystal display module includes a display panel and a lower polarizing film and an upper polarizing film arranged on two opposite sides of the display panel. A first via hole is in the lower polarizing film. A second via hole is in the upper polarizing film and arranged corresponding to the first via hole. A light shielding portion is arranged at two side edges of the second via hole. Such configuration avoids light leakage from the first via hole and the second via hole of the liquid crystal display module, and improves shooting performance of the camera module and also enhances market competitiveness.

Abstract: A display device has a main display area and a function-adding area and includes a backlight module and a display panel. The backlight module includes an optical film set and light sources. The light sources are disposed on at least one end of the optical film set that is perpendicular to a light-emitting side of the backlight module, and include first light groups and second light groups. When the display device is in a functional mode, the first light groups are turned off, the second light groups are turned on, a first dark zone is formed on the optical film set, and the function-adding area is located within the first dark zone.

Abstract: The present application provides a display device. The display device includes a display panel, a backlight module, and a light-blocking member. The backlight module is defined with a through hole penetrating the backlight module, and the light-blocking member includes a channel corresponding to the through hole. The light-blocking member can isolate other components of the backlight module from the channel to prevent light in the backlight module from irradiating into the channel, thereby solving the problem that the through hole of the backlight module in an existing under-screen camera display devices easily leaks light.

Abstract: The present application provides a display panel and an electronic device. A first sub-backlight module is arranged in a display area of the display panel, and a second sub-backlight module is arranged in an electronic component area. A light guide plate of the second sub-backlight module can be switched between a light-scattering state and a transparent state, so that the electronic component area can display images and take photos. The first light-shielding member is arranged in an accommodating space defined by the display panel body and the backlight module to avoid light leakage during shooting, so that full-screen display can be realized without light leakage.
