Mobile terminal
A mobile terminal may be provided that includes a case having a through window formed in front of the case, an optical sensor arranged in the case toward the through window, a glass formed of an opaque material to cover the through window of the case, and a window layer disposed on a behind face of the glass, with a fine hole formed above the optical sensor.
1. A mobile terminal comprising:
a case having a through hole;
a proximity sensor provided in the case, the proximity sensor includes a light transmitting unit to output a light and a light receiving unit to detect the light after being outputted from the light receiving unit;
a glass to cover the through hole; and
an opaque layer provided behind the glass, the opaque layer having a plurality of first holes provided above the light receiving device, and a second hole provided above the light transmitting device,
wherein the second hole is larger than the first holes, and at least one of the first holes is provided above the proximity sensor,
wherein a diameter of the second hole is within a range of 0.03 mm to 0.05 mm, and
wherein a distance between two of the plurality of first holes is within a range of 0.05 mm to 0.1 mm.
2. The mobile terminal according to claim 1 , wherein the optical sensor is an illuminance sensor, and the illuminance sensor includes a light receiving unit to detect light.
3. The mobile terminal according to claim 2 , further comprising a controller to control a brightness of a display based on the light detected by the light receiving unit.
4. The mobile terminal according to claim 1 , wherein the opaque layer is formed of an opaque material.
5. The mobile terminal according to claim 1 ,
wherein the plurality of first holes of the opaque layer are provided above the light receiving device, and the second hole of the opaque layer is above the light transmitting unit.
6. The mobile terminal according to claim 5 , wherein the light is an infrared ray (IR) and the second hole is an IR hole.
7. The mobile terminal according to claim 6 , wherein visible ray closure ink is provided on an area of the glass corresponding to the IR hole.
8. The mobile terminal according to claim 1 , wherein the opaque layer comprises:
a first layer; and
a second layer, provided under the first layer, to block light from a display.
9. The mobile terminal according to claim 8 , wherein the first layer is formed of a white color.
10. The mobile terminal according to claim 1 , wherein the plurality of first holes are formed by laser processing after the opaque layer is provided on the glass.
