Embodiment Construction

[0032] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present application may be practiced. Directional terms mentioned in this application, such as [upper], [lower], [front], [rear], [left], [right], [inner], [outer], [side], etc., are only for reference Additional schema orientation. Therefore, the directional terms used are used to describe and understand the present application, rather than to limit the present application. In the figures, structurally similar elements are denoted by the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clarity of understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited thereto.

[0033] Please refer to Figure 1 to Figure 6 , figure 1 It is a schematic top-view structure di...

Abstract

The invention provides a display device and a driving method thereof.The display device comprises a display module and a photosensitive module located on the non-light-emitting side of the display module, the display module is provided with a first display area and a second display area which are adjacently arranged, and a second electrode corresponding to the photosensitive module is arranged in the second display area of the display module; the second electrode has a working state and a non-working state, when the first electrode is in the working state, an electric field exists between the first electrode and the second electrode, and liquid crystal molecules in the second display area are driven by the electric field to deflect, so that the focus of light passing through the photosensitive module is changed, and the focal length of the photosensitive module is further changed; the definition of an image collected by a photosensitive module is improved, so that the problem that an image collected by a camera of an existing display screen applying an under-screen camera technology is not clear is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and a driving method thereof. Background technique [0002] The under-screen camera (Camera uNder PaNel, CUP) technology increases the screen-to-body ratio while making the entire display screen more aesthetically pleasing, and has been more and more widely used in fields such as vehicles. The existing under-screen camera technology generally realizes the under-screen camera function by punching holes or openings on the screen, and placing a camera with a fixed position at the hole / hole. However, the fixed position of the camera on the display will limit the viewing angle of the camera, and the focal length of the camera cannot be adjusted. In particular, when it is applied to the vehicle-mounted display module, since the position of the vehicle-mounted display module is also fixed and cannot be adjusted, when the distance between the position wh...
