Abstract

A display device used in the technical field of communications comprises a housing, a display panel and a light-transmitting cover plate; the display panel is disposed in the housing to form a display area constituted by the display panel and a frame area surrounding the display panel; the light-transmitting cover plate covers the housing to form the outer surface of the display device; the light-transmitting cover plate has a first light-transmitting part and a second light-transmitting part; the first light-transmitting part corresponds to the display area, and the second light-transmitting part corresponds to the frame area; the light emitted by the display panel transmits outward through the first light-transmitting part and the second light-transmitting part; the outer surface of the second light-transmitting part is provided with an optical.

First claim

What is claimed is:

1. A display device comprising:
a housing;
a display panel disposed in the housing such that a gap is formed between sides of the display panel and sides of the housing;
a light-transmitting cover plate covering the display panel and the gap to form an outer surface of the display device,
wherein the light-transmitting cover plate has a first light-transmitting part corresponding to a display area of the display panel and a second light-transmitting part corresponding only to a non-luminous area that is a frame area surrounding the display area and the gap; and
an optical part disposed on the outer surface of the second light-transmitting part,
wherein the optical part and the outer surface are planar,

wherein light emitted by the display panel transmits, through the first light-transmitting part, outward and toward a viewer of the display device;
wherein the light emitted by the display panel transmits, through the outer surface of the second light-transmitting part, outward and away from the viewer of the display device;
wherein the optical part is used to change a first direction of light exiting from the outer surface of the second light-transmitting part to be substantially the same as a second direction of light exiting from the first light-transmitting part, toward the viewer of the device;
wherein the exit surface of the second light-transmitting part is parallel to an incidence surface of the second light-transmitting part; and
wherein a first refractive index of the optical part of the second light-transmitting part is greater than a second refractive index of the second light-transmitting part.

2. The display device of claim 1 , wherein the incidence surface of the second light-transmitting part and the exit surface of the second light-transmitting part are horizontal surfaces; and the exit surface of the second light-transmitting part is provided with an optical film for forming the optical part.

3. The display device of claim 2 , wherein the light-transmitting cover plate is bonded to the housing, and the light-transmitting cover plate is bonded to the display panel such that the display panel is disposed in the housing.

4. The display device of claim 1 , wherein the light-transmitting cover plate is bonded to the housing, and the light-transmitting cover plate is bonded to the display panel such that the display panel is disposed in the housing.

5. A method for manufacturing a display device, comprising:
providing a display panel, a housing, and a light-transmitting cover plate, and disposing the display panel in the housing to form a display area constituted by the display panel and a frame area surrounding the display area, wherein the light-transmitting cover plate has a first light-transmitting part and a second light-transmitting part;
disposing the light-transmitting cover plate to cover the display panel to form an outer surface of the display device, and enabling the first light-transmitting part to correspond to the display area and enabling the second light-transmitting part to correspond only to a non-luminous area that includes the frame area,
wherein light emitted by the display panel transmits, through the outer surface of the second light-transmitting part, outward and away from a viewer of the display device; and
providing the outer surface of the display device adjacent to the second light-transmitting part with an optical part used to change an exit direction of light emitted by the display panel through the second light-transmitting part so as to enable a first direction of light exiting from the second light-transmitting part to be substantially the same as a second direction of light exiting from the first light-transmitting part and toward the viewer of the device,
wherein the optical part is planar,
wherein the optical part is parallel to an incidence surface of the second light-transmitting part, and
wherein a first refractive index of the optical part is greater than a second refractive index of the second light-transmitting part.

6. The method of claim 5 , further comprising:
configuring the incidence surface of the second light-transmitting part and the outer surface of the display device adjacent to the second light-transmitting part to be horizontal surfaces; and
bonding an optical film to an exit surface of the second light-transmitting part to form the optical part.

7. The method of claim 6 , further comprising:
bonding the light-transmitting cover plate to the housing; and
bonding the display panel to the light-transmitting cover plate such that the display panel is secured in the housing.

8. The method of claim 5 , further comprising:
bonding the light-transmitting cover plate to the housing; and
bonding the display panel to the light-transmitting cover plate such that the display panel is secured in the housing.

9. A terminal comprising:
a display device that comprises:
a housing,
a light-transmitting cover plate,
a display panel disposed in the housing to form a display area constituted by the display panel and a frame area surrounding the display panel,
wherein the light-transmitting cover plate covers the display panel to form an outer surface of the display device;
wherein the light-transmitting cover plate has a first light-transmitting part corresponding to the display area and a second light-transmitting part corresponding only to a non-luminous area that includes the frame area;
wherein light emitted by the display panel transmits outward and toward a viewer through the first light-transmitting part and outward and away from the viewer through the second light-transmitting part; and
an optical part provided on the outer surface of the display device adjacent to the second light-transmitting part,
wherein the optical part is used to change an exit direction of light emitted by the display panel through the second light-transmitting part so as to enable a first direction of light exiting from the second light-transmitting part to be substantially the same as a second direction of light exiting from the first light-transmitting part and toward the viewer,
wherein the outer surface is parallel to an incidence surface of the second light-transmitting part, and
wherein a first refractive index of the optical part is greater than a second refractive index of the second light-transmitting part.

10. The terminal of claim 9 , wherein the incidence surface of the second light-transmitting part and an exit surface of the second light-transmitting part are horizontal surfaces; and the exit surface of the second light-transmitting part is provided with an optical film to form the optical part.
