Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
In order to solve the problem that the use effect of the off-screen camera is affected by the misalignment of the film layer in the display mode switching process in the prior art, an embodiment of the invention provides a display device, which is described in detail below with reference to the schematic cross-sectional structures of two display modes of the display device provided in fig. 3 and 4.
Specifically, the display device includes:
the display panel 210 includes an accommodation hole 211, where the display panel 210 includes a display screen and a plurality of auxiliary structure layers, such as a heat dissipation layer, a buffer layer, a back plate, and the like, disposed on a side of the display screen facing away from a light-emitting direction, and the accommodation hole 211 may be formed only in the auxiliary structure layer or formed in the auxiliary structure layer and the display screen according to a display requirement at the accommodation hole 211;
a camera head assembly 230 disposed in the accommodation hole 211;
the display panel 210 at least includes a first display mode and a second display mode, where the display mode refers to a macroscopic shape of the display panel 210 during displaying, and during switching between the first display mode and the second display mode, the shape of the display panel 210 changes, and at this time, the film layers in the display panel 210 inevitably shift, for example, in the first display mode, referring to fig. 3, the film layers in the display panel 210 do not shift, and when switching to the second display mode, the film layers in the display panel 210 start to shift along with the deformation of the display panel, so that the internal shape of the receiving hole 211 in the display panel 210 also changes, that is, as shown in fig. 4, at this time, the camera assembly 230 moves towards a predetermined direction D1, so that the camera assembly 230 and the side wall of the receiving hole 211 always keep a safe distance, so as to prevent the camera assembly 230 from colliding with the side wall of the accommodating hole 211 to affect the using effect of the camera assembly 230. When the second display mode is switched to the first display mode, the camera assembly 230 moves in the opposite direction, and the safe distance is kept between the camera assembly and the side wall of the accommodating hole 211.
Here, the safety distance is a distance that can ensure that the camera head assembly does not interfere with the receiving hole. The safety distance is not suitable to be too large, otherwise, the hole diameter of the accommodating hole needs to be designed to be larger, so that the display effect is influenced to a certain extent; meanwhile, the safety distance is not too small, otherwise, the requirement on the movement control precision is too high, and the manufacturing cost is greatly improved. Typically, the safety distance may be set to less than 100 microns, depending on the actual process requirements.
It is understood that, in this embodiment, the camera assembly may be replaced with other required under-screen devices, such as a flash lamp, etc., according to the actual process requirements, and the invention is not limited thereto.
In addition, in the embodiment, the predetermined direction D1 is determined by the direction of the misalignment of the film layers in the display panel 210, and the direction of the misalignment of the film layers in the display panel 210 is determined by the display mode switching manner, that is, the predetermined direction D1 is not a fixed direction but is determined by the switching manner between the first display mode and the second display mode.
In an embodiment, the display device further includes a cover plate 220, the cover plate 220 is attached to the side surface of the light emitting direction of the display panel 210 through an optical transparent adhesive layer, the side surface of the cover plate 220 close to the display panel 220 is provided with annular ink 221, the portion of the cover plate 220 corresponding to the central area of the annular ink 221 provides a window for the camera assembly 230, and in the process that the camera assembly 230 moves towards the predetermined direction, according to the degree of dislocation of the film layer in the display panel 210, the speed and distance of movement of the camera assembly 230 are precisely controlled, so that the shooting visual angle of the camera assembly 230 always falls into the window, and thus the shooting effect and quality of the camera assembly 230 are ensured.
In this embodiment, the film layer misalignment distance is determined by the display form change angle of the display panel and the film layer properties of the display panel, so that according to a simulation experiment, a formula 1 for calculating the film layer misalignment distance of the display panel from the display form change angle can be obtained, a formula 2 for calculating the camera assembly movement distance from the display form change angle can be obtained from the formula 1, and the camera assembly movement can be accurately controlled through the formula 2.
In addition, in the actual operation process of the display device, the actual distance and the theoretical calculation distance of the dislocation of the display panel film layer may have slight deviation, and a distance sensor may be arranged on the inner side wall of the accommodating hole or the outer side wall of the camera assembly to monitor the distance between the camera assembly and the accommodating hole in real time and to assist in controlling the movement of the camera assembly.
In one embodiment, the first display mode is an expanded display mode, and the display panel is completely expanded to form a flat display surface; the second display form is a folding display form or a rolling display form, namely the display device is a folding display device or a rolling display device.
In an embodiment, since the camera head assembly 230 needs to move in the predetermined direction D1 during the switching between the first display mode and the second display mode, the receiving hole 211 needs to reserve a certain space for the camera head assembly 230 to move in the predetermined direction D1, which is equivalent to that the center L1 of the camera head assembly 230 is offset from the center L2 of the receiving hole 211 by a predetermined distance a along the predetermined direction D1 when the display panel is in the first display mode, i.e., the unfolded display mode.
Further, the size of the predetermined distance d depends on the degree of change of the display form of the display panel, and specifically, when the display panel is in the folded display form or the rolled display form, the larger the folding angle or the rolling angle is, the larger the misalignment degree of the film layer of the display panel is, and accordingly, the predetermined distance d needs to be set larger.
In the above embodiments, the camera assembly moves in the predetermined direction while the display panel switches the display mode, and the manner of controlling the movement of the camera assembly may be various, and specific embodiments will be further described below.
