In an alternative embodiment, the image capture element 30 is a wide-angle camera. When the image capturing element 30 is a wide-angle camera, the wide-angle camera may be directly integrated at any position of the non-display area 102 of the display cover 10. For example, the wide-angle camera may be obliquely placed in a raised manner at the upper edge of the display cover 10, so that the viewing angle of the wide-angle camera covers at least the display area 101 and a narrow circle of non-display area 102 surrounding the outer edge of the display area 101. The wide-angle camera is directly integrated at any position of the non-display area 102 of the display cover plate 10, and the position of the image capturing element 30 does not need to be additionally arranged, so that the volume of the whole frameless display device 100 is reduced, and the installation is convenient.
The structure and the position relationship of the controller 40 are not particularly limited, as long as the controller 40 can dynamically adjust the display content and the display background according to the image information to ensure that the display background is hidden visually and the display content is displayed. In an alternative embodiment, the controller 40 is a microprocessor integrated with the image acquisition assembly 30. In an alternative embodiment, the controller 40 may also be a separately provided processor.
In this embodiment, the frameless display device 100 includes a display cover 10, a light emitting device 20, an image capturing device 30 and a controller 40. The display cover 10 includes a display area 101 for display and a non-display area 102. The light emitting element 20 and the image capturing element 30 are respectively disposed on both sides of the display cover 10. The light emitting element 20 emits display content and display background projected in the display area 101. The image capturing element 30 is used to capture image information of the display cover 10 at least including the display area 101. The controller 40 is electrically connected to the light emitting element 20 and the image capturing element 30, respectively. The controller 40 determines the difference between the display background in the display area 10 and the non-display area 102, and dynamically adjusts the background of the display area to ensure the display effect of the background part is consistent with the display effect of the non-display area 102 of the display cover 10, and the adjustment is dynamic and closed loop, and can be adjusted along with the change of the environment to ensure the consistency of the effect.
In one alternative embodiment, the light emitting element 20 is fixedly disposed on one side of the display cover 10. Optionally, the light emitting element 20 is directly opposite to the display area 101.
The light emitting element 20 and the display cover 10 may be mounted on the back surface of the display cover 10 by an adhesive. The display content and the display background emitted by the light emitting element 20 will be presented to the viewer through the display area 101. At this time, the image capturing element 30 may be disposed right opposite to the front surface of the display cover 10 with a certain interval between the image capturing element 30 and the display cover 10. When the image capturing element 30 is spaced apart from the display cover 10, the image capturing element 30 may be a general camera or a wide-angle camera. In an alternative embodiment, the image capturing element 30 may be fixedly disposed on the front surface of the display cover 10. When the image capturing element 30 is fixedly disposed on the front surface of the display cover 10, the image capturing element 30 is directly integrated on any position of the non-display area 102 of the display cover 10. Since the image capturing element 30 needs to capture image information of the display panel 10, the image capturing element 30 may be a wide-angle camera or other image capturing element with a larger viewing angle.
Referring to fig. 2, in one embodiment, the light emitting device 20 is a projector. Since the projector needs to be at a distance from the projection screen, in an alternative embodiment, the projector is spaced from the display cover 10. The projector emits display content and display background to the display area 101. At this time, the image capturing element 30 may be disposed right opposite to the front surface of the display cover 10 with a certain interval between the image capturing element 30 and the display cover 10. When the image capturing element 30 is spaced apart from the display cover 10, the image capturing element 30 may be a general camera or a wide-angle camera. The viewing angle of the image capturing element 30 covers at least the display area 101 and a portion of the non-display area 102 connected to the outer edge of the display area 101. That is, the viewing angle of the image capturing element 30 covers at least the display area 101 and a narrow circle of non-display area 102 surrounding the outer edge of the display area 101.
Referring to fig. 3, in an alternative embodiment, the image capturing element 30 may also be fixedly disposed on the front surface of the display cover 10. When the image capturing element 30 is fixedly disposed on the front surface of the display cover 10, the image capturing element 30 may be a wide-angle camera or other image capturing element with a larger viewing angle, since the image capturing element 30 needs to capture the image information of the display panel 10. The viewing angle of the image capturing element 30 covers at least the display area 101 and a portion of the non-display area 102 connected to the outer edge of the display area 101. That is, the viewing angle of the image capturing element 30 covers at least the display area 101 and a narrow circle of non-display area 102 surrounding the outer edge of the display area 101.
Please refer to fig. 4, which is a diagram illustrating a display effect of a conventional display device on a display panel according to the present application. As can be seen from fig. 4, since the display background in the display area 101 is visually different from the appearance in the non-display area 102, there is a very obvious boundary trace, which is visually perceived by the viewer as a frame.
Please refer to fig. 5, which is a diagram illustrating a display effect of the frameless display device 100 according to the present application on a display panel. As can be seen from fig. 5, by adjusting the color and brightness of the display background of the display area 101 so that the display background and the non-display area 102 are integrated, there is no visual difference between the display background in the display area 101 and the appearance in the non-display area 102, and therefore, only the display content can be visually seen, and thus, the existence of the entire display area cannot be seen.
Referring to fig. 6, an embodiment of the present application provides a borderless display method. The borderless display method comprises the following steps:
s10, image information of the display cover 10 including at least the display area 101 is acquired by the image acquisition element 30. In step S10, the display cover 10 has a display area 101 and a non-display area 102. The image capturing element 30 is disposed on the front surface of the display cover 10. The image information may include an image within the display area 101 and an image of a part or all of the non-display area 102.
S20, the controller 40 obtains the image information, and dynamically adjusts the display content and the display background emitted by the light emitting device 20 according to the image information and the current light environment, so as to ensure that the display background is hidden visually and the display content is displayed.
In step S20, the light emitting element 20 is disposed on the back surface of the display cover 10. The light emitting element 20 emits display content and display background to the display area 101. The controller 40 is electrically connected to the light emitting element 20 and the image capturing element 30, respectively.
Of course, the borderless display method may be applied to the borderless display device 100 described in any of the above embodiments. In this embodiment, the light emitting element 20 emits display content and display background to be projected in the display area 101. The image capturing element 30 is used to capture image information of the display cover 10 at least including the display area 101. The controller 40 determines the difference between the display background in the display area 10 and the non-display area 102, and dynamically adjusts the background of the display area to ensure the display effect of the background part is consistent with the display effect of the non-display area 102 of the display cover 10, and the adjustment is dynamic and closed loop, and can be adjusted along with the change of the environment to ensure the consistency of the effect.
In one embodiment, the step S20 of the controller 40 acquiring the image information, and dynamically adjusting the display content and the display background emitted by the light emitting elements 20 according to the image information and the current light environment to ensure that the display background is visually hidden, and displaying the display content includes:
the controller 40 adjusts the color and brightness of the display background according to the image information and the current light environment to ensure that the display background is hidden visually and the display content is displayed. The non-display area 102 reflects different colors in different light environments. The controller 40 uses the light environment as a factor to ensure that the display background is visually hidden by adjusting the color and brightness of the display background. In addition, under different light environments, the color and brightness of the display content also need to be adjusted to embody the technological sense, for example, the color and brightness of the display content can be brighter at night to achieve the purpose of well displaying the display content.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
