Problems solved by technology

However, in the application of terminal equipment, transparent display devices cannot use traditional backlight and external light as the light source of the display mode.
[0003] Therefore, it is necessary to propose a new backlight module and transparent display device to increase the screen-to-body ratio of the display device and solve the problem that the transparent display device in the prior art cannot use traditional backlight and external light as the light source of the display mode.

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a camera area and a backlight area. The backlight area surrounds the camera area. The camera area comprises a transparent irradiation area and a non-transparent irradiation area, wherein the non-transparent irradiation area surrounds the transparent irradiation area. The non-transparent irradiation areais provided with a lamp panel; and the lamp panel is provided with at least one lamp bead. Under a display mode, the camera area obtains a uniform light source to realize normal display of the cameraarea under the display mode of the display device, thereby realizing true 100% screen-to-body ratio; and under a lighting mode of a camera module, a light source of the lamp bead is turned off to prevent influence on lighting of the camera module.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module and a transparent display device. Background technique [0002] With the innovation and development of display technology, high-screen-to-body ratio screens have become the mainstream trend in the application of new-generation terminal equipment. Due to the lighting requirements of some functional devices in terminal equipment, such as cameras and light sensors, the screen-to-body ratio of display screens is difficult. Improvement, a transparent display device that takes into account both lighting and display becomes the best choice to meet this demand. However, in the application of terminal equipment, the transparent display device cannot use the traditional backlight source and external light as the light source of the display mode. [0003] Therefore, it is necessary to propose a new backlight module and transparent display device to increase the screen-to-body ratio o...
