The present disclosure provides a display equipment. The display equipment includes a display device and an anti-peep member. The anti-peep member includes a shielding part and a light transmissive part. The shielding part is used to reduce viewing angles of the display device. Furthermore, the anti-peep member is disposed on a light exiting surface of the display device in a first state, and the anti-peep member is disposed outside the light exiting surface of the display device in a second state. By disposing the anti-peep member, the shielding part is disposed on the light exiting surface of the display device in the first state, and the shielding part reduces viewing angles of the display device. Meanwhile, the anti-peep member is disposed outside the light exiting surface of the display device in the second state, so that the viewing angles of the display device are recovered to conventional viewing angles. Therefore, this makes the viewing angles of the display device be reduced in the first state, thereby preventing displayed contents of the display device from being leaked and preventing privacy leakage, and solving the technical problem of privacy leakage due to wide viewing angles existing in current display devices.
It should be noted that in the embodiment of the present disclosure, the light exiting surface indicates an outermost film layer penetrated by the light emitted from the display device, the backlight surface indicates an outermost film layer of a back surface of the display device disposed opposite to the light exiting surface, the first state indicates a display state of reducing the viewing angles to protect privacy, and the second state indicates a display state of not processing the viewing angles of the display device so that viewing angles are normal.
In an embodiment, the shielding part includes a light absorbing portion. The light absorbing portion is disposed on an edge of the light exiting surface of the display device in the first state. The light absorbing portion is used to absorb light emitted from the display device. For example, the shielding part 121 in
In an embodiment, the light absorbing portion can be manufactured by using light absorbing materials; for example, using materials that can absorb blue light or ultraviolet light, such as a blue light absorbent or an ultraviolet light absorbent. Furthermore, the blue light absorbent includes iron oxide, xanthophyll, or lead sulfochromate yellow (CrO5Pb2), and the ultraviolet light absorbent includes benzophenone, o-aminobenzoic acid salts, or dibenzoylmethane.
In an embodiment, the light absorbing portion can determine intensity of absorbed light according to a requirement. For example, part of the light can be absorbed, and other part of the light is allowed to pass through, so that at while reducing the viewing angles, this position is still able to display normally in the front view direction of the light exiting surface.
In an embodiment, a thickness of the light transmissive part is same as a thickness of the shielding part. When disposing the anti-peep member, the shielding part and the light transmissive part can be spliced to form the anti-peep member. Therefore, when forming the shielding part, a size of the shielding part is determined according to different viewing angles of different display equipment, while the thicknesses of the light transmissive part and the shielding part are consistent, and a splicing seam of the anti-peep member formed by splicing does not affect display, which makes the anti-peep member on the light exiting surface of the display device be flat. Therefore, when displaying, the display screen is a complete display screen, and problems such as fragmentation or fold marks do not occur on the display screen.
In an embodiment, as illustrated in
In an embodiment, the light shielding portion includes a light shielding material.
In an embodiment, a material of the light transmissive part includes transparent glass. When manufacturing the anti-peep member, transparent glass or transparent plastic are used as the material of the light transmissive part. Afterwards, when manufacturing the shielding part, a groove can be dug at the edge of the light transmissive part, and the shielding part can be disposed inside the light transmissive part. Or, the light transmissive part is disposed, and the shielding part is disposed on the light transmissive part. In consideration for the light transmissive part to not affect display effect, the material of the light transmissive part can be same as a material of a cover plate of the display device, so that the light passes through well, and the display effect is not affected.

In an embodiment, the first shielding section includes a light shielding portion, and the second shielding section includes a light absorbing portion.
In an embodiment, the anti-peep member is connected to the display device, and the shielding part is integrated with the light transmissive part. By making the anti-peep member be connected to the display device, during changing between the first state and the second state, the anti-peep member connected to the display device is directly moved to the light exiting surface of the display device, or the anti-peep member is removed from the light exiting surface of the display device.
In an embodiment, as illustrated in
In an embodiment, the connection part and the light transmissive part are integrated into one piece, and then the shielding part is formed on the light transmissive part. The connection part and the light transmissive part can be formed by using transparent glass or transparent plastic, after that, the shielding part and the light transmissive part can be connected to the combination part by the connection part, so that the shielding part and the light transmissive part can be disposed between the display device and the combination part.
In an embodiment, as illustrated in
In an embodiment, the combination part further includes a power source. The power source is disposed in a middle of the accommodating chamber. Disposing the power source in the combination part can supply electricity to the connection part by the power source, so that the connection part controls movement of the shielding part and the light transmissive part, thereby allowing the anti-peep member to reduce the viewing angles of the display device in the first state, while the viewing angles of the display device are not affected in the second state. Or, the power source can supply a voltage to the display device to make the display device display.
In an embodiment, the power source includes a solar power source, which is charged by solar power and can save resources, and reduces charging difficulty and charging cost.

In an embodiment, the power source is electrically connected to the display device, and the power source acts as a power supply of the display device, or the power source acts as a power supply of the connection part, so that the power source is electrically connected to the display device. This enables the power source to drive a driving circuit of the display device, thereby making the display device emit light to display, and can also allow the power source to provide electricity to the connection part to allow the connection part to guide the movement of the shielding part and the light transmissive part.
In an embodiment, the connection component includes an optically clear adhesive. In the anti-peep member of the display device, the optically clear adhesive is directly disposed in the anti-peep member. By using the optically clear adhesive to bond the anti-peep member onto the display device, the display device structure does not need to be changed.
In an embodiment, the connection component includes screws, and screw threads matching the screws are disposed on the display device. In the cooperating composition of the combination part and the display device, the screw threads may be formed on the lateral surface of the display device first, and then the screws are disposed on the anti-peep member. By matching the screws and the screw threads to each other, the display device and the anti-peep member have a tight connection, and forming the screw threads on the lateral surface of the display device would not have an effect on the display of the display device.
In an embodiment, the connection part includes a hinge. When the connection part is guiding the shielding part and the light transmissive part, the shielding part and the light transmissive part can be guided by manually rotating the connection part, or the circuit-driven hinge can guide the shielding part and light transmissive part, or a bending arm structure may act as the connection part, so the bending arm structure can be made to rotate around the display device under power supplied by the power source and driving of the circuit to guide the shielding part and the light transmissive part to move.
