Abstract

Disclosed is an electronic apparatus including: a housing; a transparent glass substrate covering at least a portion of the housing, and including a first surface facing a first direction and a second surface facing a second direction opposite to the first direction; a display panel accommodated in the housing, covered with the glass substrate, and including at least one opening configured for light transmission in a display area where an image is displayed; and an ink layer having an opaque color, applied to an opaque area surrounding an edge of the opening to form a light-transmission area corresponding to the opening on the second surface, the ink layer including an inclined area where the ink layer becomes narrower in the second direction from the second surface.

Claims (25)

1. An electronic apparatus comprising:

a housing;

a transparent glass substrate covering at least a portion of the housing, and comprising a first surface facing a first direction and a second surface facing a second direction opposite to the first direction;

a display panel accommodated in the housing, covered with the glass substrate, and comprising at least one opening configured for light transmission in a display area where an image is displayed;

an ink layer having an opaque color, applied to an opaque area surrounding an edge of the opening to form a light-transmission area corresponding to the opening on the second surface, the ink layer comprising an inclined portion where the ink layer becomes narrower in the second direction from the second surface; and

a laser dot-pattern area adjacent to the opaque area and formed on the second surface of the glass substrate.

2. The electronic apparatus of claim 1 , wherein the laser dot-pattern area is formed by at least one of a carbon dioxide (CO2) laser or a green laser.

3. The electronic apparatus of claim 2 , wherein an inclined area of dots comprising the laser dot-pattern formed based on the CO2 laser is different in inclination angle from an inclined area of dots comprising the laser dot-pattern formed based on the green laser.

4. The electronic apparatus of claim 1 , further comprising an optical sensor,

wherein the opening is configured to accommodate at least a portion of the optical sensor.

5. The electronic apparatus of claim 1 , further comprising an adhesive layer interposed between the glass substrate and the display panel attaching the display panel and the glass substrate.

6. The electronic apparatus of claim 5 , wherein the adhesive layer comprises an optically clear adhesive (OCA).

7. The electronic apparatus of claim 5 , wherein the inclined area comprises a first inclined surface at an outer edge of the ink layer and in contact with the adhesive layer.

8. The electronic apparatus of claim 7 , further comprising a first laser dot-pattern area formed along an edge of the first inclined surface, on the second surface of the glass substrate in contact with the adhesive layer.

9. The electronic apparatus of claim 7 , wherein the inclined area comprises a second inclined surface at an inner edge of the ink layer surrounding the light-transmission area.

10. The electronic apparatus of claim 9 , further comprising a second laser dot-pattern area formed along an edge of the second inclined surface, on the second surface of the glass substrate.

11. The electronic apparatus of claim 1 , wherein the ink layer comprises a black ink layer printed on the glass substrate.

12. The electronic apparatus of claim 11 , wherein the inclined area is formed by machining the black ink layer using a CO2 laser.

13. An electronic apparatus comprising:

a housing;

a transparent glass substrate covering at least a portion of the housing, and comprising a first surface facing a first direction and a second surface facing a second direction opposite to the first direction;

a display panel accommodated at least partially in the housing, covered with the transparent glass substrate, the display panel including a display area where an image is displayed, a light-transmission area through which light is to be transmitted, and an opaque area surrounding the light-transmission area and forming a boundary between the display area and the light-transmission area;

an ink layer having an opaque color, applied to the opaque area; and

an adhesive layer interposed between at least the glass substrate and the display panel attaching the display panel and the glass substrate,

wherein the ink layer comprises an inclined portion where the ink layer becomes narrower in the second direction from the second surface toward the display panel, and wherein the adhesive layer adhering to the glass substrate and the inclined portion of the ink layer prevents or reduces bubbles from being formed in the adhesive layer.
