Referring to fig. 1-2, the present invention provides an optical device with an extended display effect, and a main body of the optical device 10 may be made of any material such as metal or plastic. The optical device 10 is a hollow hood-shaped structure, one end of the hood-shaped structure forms a first opening 11, the other end of the hood-shaped structure forms a second opening 12, the first opening 11 and the second opening 12 are the same in shape, and the first opening 11 is smaller than the second opening 12; the two openings of the optical device 10 may be circular, oval, square or any other shape that can match the display area of the display screen. The inner surface of the cover-shaped structure can reflect light, specifically, the inner surface of the cover-shaped structure is provided with a reflective layer 130, and if the cover-shaped structure is made of transparent material, the reflective layer can be selectively generated on either the inner surface or the outer surface. When the display screen emits light below the optical device, the light is reflected by the reflective layer 130, and is emitted from the second opening 12 to enter human eyes, so that the display effect of extending the image of the display screen is formed. Preferably, the reflective layer 130 is a plated metal layer formed on the inner surface of the optical device by plating, so as to reflect light. The electroplated metal layer can be one of an electroplated aluminum layer, an electroplated nickel layer, an electroplated cadmium layer, an electroplated copper layer, an electroplated silver layer or an electroplated gold layer, and can also be other reflecting materials such as a glass coating. When the angle theta is too large, light rays on the display screen cannot be reflected to the inclined plane of the optical device 10, the problem that the optical device fails is caused, namely, light emitted by the display screen cannot be reflected through the optical device 10, so that blank areas without display pictures appear around the display screen, and the image expansion effect cannot be achieved, according to the difference of the sizes of the two openings, the included angle between the surface of the cover-shaped structure and the vertical direction is 0< theta > not more than 45 degrees, and the inventor proves that when the angle theta is below 45 degrees, the picture extension effect is good, and the preferable angle is 15-25 degrees.

Specifically, in this embodiment, the optical device 10 includes a third surface 133, a fourth surface 134, a fifth surface 135, and a sixth surface 136 that are connected to each other, the third surface 133, the fourth surface 134, the fifth surface 135, and the sixth surface 136 are all isosceles trapezoids, and the first opening 11 and the second opening 12 are both square. The optical device 10 has four smooth surfaces, and a reflective layer is plated on the inner surface. The plane where the first opening 11 is located is parallel to the plane where the second opening 12 is located, and the central projections of the first opening 11 and the second opening 12 perpendicular to the plane where the first opening and the second opening are located are overlapped, so that the sizes and the inclination angles of the third surface 133, the fourth surface 134, the fifth surface 135 and the sixth surface 136 of the optical device 10 are all the same, the peripheral extension degrees of the display screen image after extension are the same, and the aesthetic property of the picture is improved.

In a preferred embodiment, when the optical device is designed, the shapes of the first opening 11 and the second opening 12 are the same as the shape of a display area of a display screen on which the optical device is to be mounted, preferably, the shapes of the first opening 11 and the second opening are both square or rectangular, the size of the first opening 11 is the same as the size of the display area of the display screen, the optical device can be mounted on the display screen in a clamped manner by arranging a protruding buckle on the edge of the first opening 11, or the first opening 11 and the display area are bonded together through a transparent adhesive, and the transparent adhesive can be common OCA adhesive or SCA adhesive on the market.

In a preferred embodiment, as shown in fig. 2, the width of the first opening of the optical device 10 is L, the height H after the optical device is laid flat is greater than or equal to 6 and less than or equal to 8, and preferably is 7, and under the ratio, the image stretching effect is good, and the situations that the H value is too large, the image stretching is too large, the appearance is affected, or the H value is too small, so that the image stretching effect of the optical device is not obvious do not occur. The H value may be set according to the size of the display screen or the size of the screen extension area, and the larger the H value is, the more the extended portion of the screen of the display screen is.

As shown in fig. 3, the present invention further provides a display panel 20, wherein the optical device 10 having the extended display screen effect is mounted on a display surface of the display panel 20, wherein a size and a shape of a first opening 11 of the optical device 10 are the same as a size and a shape of a display area of the display panel 20, and the first opening 11 is fixed to the display area of the display panel 20 by a transparent adhesive.

As shown in fig. 4, the present invention further provides a display device 40, which includes a mounting frame 41 and the display screen, wherein the display screen is mounted in the mounting frame 41, the first opening 11 of the optical device 10 has the same size as the display area of the display screen, and the second opening of the optical device 10 has the same size as the inner frame of the mounting frame 41. The aspect ratio of the display area of the display screen is as follows: 21:9 or 16:9, the display device in the proportion meets the aesthetic requirement of human body on visual display, and can attract higher attention. In this embodiment, the display device further includes a transparent cover glass fixed on the mounting frame 41, which serves to encapsulate the display screen and the optical device 10 and improve the aesthetic property of the display device. As can be seen from fig. 4, the content displayed on the display screen forms a picture extension under the reflection of the optical device 10, resulting in a stereoscopic display effect, and has different extension effects when viewed from different angles and distances. Fig. 5 is a front view of the screen extension effect of the display device, and it can be seen that the inner portion of the dotted line a is a display screen display area, and the outer portion of the dotted line a is a screen extension area between the outer portion of the dotted line a and the installation frame. The display device in the utility model is preferably an electronic photo frame or an advertisement player, the extending display effect of the display device improves the ornamental performance of the display device, and the immersion of a viewer is greatly enhanced.
