Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
As shown in fig. 1, the present embodiment provides a display device and a terminal device, where the terminal device includes the display device, and the terminal device may be a television, an advertisement screen, and the like, which is not limited specifically herein.
The display device comprises a transparent cover plate 1 and a screen 2 which is arranged on the inner side of the transparent cover plate 1 and is right opposite to the transparent cover plate 1, and the transparent cover plate 1 is used for protecting the screen 2. Illustratively, the transparent cover plate 1 is a rigid transparent cover plate 1. The internal surface and/or the surface of transparent cover plate 1 are equipped with dull polish layer to reduce ambient light reflection and reduce glare effect, alleviate human vision fatigue, promote user's visual experience and touch and experience.
The display device further comprises a driving unit 4, wherein the driving unit 4 is used for driving the transparent cover plate 1 to reciprocate, and the reciprocating direction of the transparent cover plate 1 is vertical to the thickness direction of the transparent cover plate 1.
When the display device works, if the transparent cover plate 1 is not moved, the frosting layer on the surface of the transparent cover plate 1 can interfere with the pixel array of the screen 2 by light rays, so that uniformly distributed moire fringes are generated, the moire fringes are irregular flash points, and the visual experience of a user can be seriously influenced. When the transparent cover plate 1 moves back and forth, the relative position between the transparent cover plate 1 and the screen 2 is changed continuously, and the Moire patterns are also changed continuously. Because the human eyes have the characteristic of vision persistence, when the picture entering the human eyes in a short time is constantly changed, the visual picture formed by the brain can become the luminance integral in a period of time, so that the Moire patterns are automatically formed into space homogenization by the brain, then, the user can not observe a flash point any more, the user experience is greatly improved, and the visual fatigue and the like are relieved.
In another embodiment, the screen 2 may be configured to be capable of reciprocating, and the driving unit 4 drives the screen 2 to reciprocate, and the reciprocating direction of the screen 2 is perpendicular to the thickness direction of the screen 2.
Alternatively, the driving unit 4 is a linear motor, and the driving unit 4 is electrically connected to a control main board of the display device, so as to supply power to the driving unit 4 and control the driving unit 4 to operate through the control main board. Because the relative movement amplitude of the transparent cover plate 1 and the screen 2 is very small, the obvious space homogenization effect can be generated, therefore, the movement precision of the driving unit 4 for driving the transparent cover plate 1 and the screen 2 to move relatively is less than 10 mu m, and the flash point phenomenon of the screen 2 can be eliminated only by controlling the transparent cover plate 1 to do micron-scale periodic reciprocating motion through the driving unit 4.
Alternatively, the direction in which the transparent cover plate 1 reciprocates is a single direction. For example, the transparent cover 1 can be reciprocally moved in the length direction thereof, or the transparent cover 1 can be reciprocally moved in the width direction thereof. Further, the direction in which the transparent cover 1 reciprocates may also be two directions, for example, the transparent cover 1 can reciprocate in both the width direction and the length direction thereof. However, compared with the transparent cover plate 1 which performs reciprocating motion in a single direction, the structure is relatively complex and the cost is high.
Alternatively, the screen 2 is a non-touch screen, since the transparent cover 1 is always in motion when the display device is in operation.
Optionally, in the transparent cover plate 1 and the screen 2, a structural member capable of reciprocating is provided with a plurality of driving units 4 to improve stability during movement of the transparent cover plate 1. Illustratively, four driving units 4 are provided, four driving units 4 are respectively provided at four corners of the transparent cover plate 1, and two driving units 4 are respectively provided at two opposite sides of the transparent cover plate 1.
Optionally, the screen 2 is always completely shielded by the transparent cover plate 1 to improve the aesthetic property of the whole display device. Illustratively, the length of the screen 2 along the first direction is smaller than the length of the transparent cover plate 1 along the first direction, the length of the screen 2 along the second direction is smaller than the length of the transparent cover plate 1 along the second direction, the first direction is the length direction of the transparent cover plate 1 and the screen 2, and the second direction is the width direction of the transparent cover plate 1 and the screen 2.
Example two
The present embodiment is different from the first embodiment in that, as shown in fig. 2, when the transparent cover 1 can reciprocate, the screen 2 and the transparent cover 1 are disposed at an interval to improve the smoothness of the reciprocating movement of the transparent cover 1.
In order to improve the stability of the transparent cover plate 1 during reciprocating movement, the display device further comprises a support frame 5, the support frame 5 is used for supporting the transparent cover plate 1, and the transparent cover plate 1 is connected with the support frame 5 in a sliding mode along the reciprocating movement direction of the transparent cover plate 1.
In addition, the foregoing is only a preferred embodiment of the present invention and the technical principles applied thereto. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious modifications, rearrangements and substitutions without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
