FIG. 2 is a partly schematic diagram of the electronic device 1000 according to the embodiment of the present invention. FIG. 3 is a partly exploded diagram of the electronic device 1000 according to the embodiment of the present invention. FIG. 4 is a functional block diagram of the electronic device 1000 according to the embodiment of the present invention. As shown in FIG. 1 to FIG. 4, the electronic device 1000 includes a casing 1, a circuit board 2, a panel module 3, a first backlight module set 4, a second backlight module set 5, a third backlight module set 6 and a control unit 7. In this embodiment, the electronic device 1000 is a smart phone, the panel module 3 is a touch panel module, but the present invention is not limited thereto.
Furthermore, the circuit board 2 is disposed inside the casing 1 and installed with a first operating system and a second operating system. For example, the first operating system can be a Windows Operating System, the second operating system can be an Android Operating System, but the present invention is not limited thereto. The panel module 3 is installed on the casing 1. In this embodiment, the casing 1 includes a front housing 10 and a rear housing 11. The front housing 10 is assembled with the rear housing 11, so as to form the casing 1 for preventing inner components of the electronic device 1000 from damage due to collision and so on.
In addition, the panel module 3 has a first icon pattern set 30, a second icon pattern set 31 and a third icon pattern set 33. The panel module 3 includes a cover lens 34 and a touch glass 35, and the cover lens 34 has a rear side 340 whereon the first icon pattern set 30, the second icon pattern set 31 and the third icon pattern set 33 are formed. The touch glass 35 is coupled to the rear side 340 of the cover lens 34 and disposed between the cover lens 34 and the circuit board 2. Please refer FIG. 5 to FIG. 7. FIG. 5 to FIG. 7 are diagrams of the cover lens 34 in different statuses according to the embodiment of the present invention. In order to form the first icon pattern set 30, the second icon pattern set 31 and the third icon pattern set 33 on the rear side 340 of the cover lens 34, at first, a plurality of first icon areas 341, a plurality of second icon areas 342, a plurality of third icon areas 343, an operating window area 344 and a peripheral area 345 are defined on the rear side 340 of the cover lens 34, as shown in FIG. 5.
Afterwards, a cover lens opaque layer 346 is formed on the plurality of first icon areas 341, the plurality of second icon areas 342, the plurality of third icon areas 343 and the peripheral area 345, except for operating window area 344, as shown in FIG. 6. In this embodiment, the cover lens opaque layer 346 is made of opaque ink material with opacity from 89% to 95%, i.e., the opacity of the cover lens opaque layer 346 is from 89% to 95%. As a result, the areas covered by the cover lens opaque layer 346 (i.e., the first icon areas 341, the second icon areas 342, the third icon areas 343 and the peripheral area 345) is opaque with the opacity from 89% to 95%. Instead, the operating window area 344 is not covered by the cover lens opaque layer 346 and still transparent.
Finally, a light-proof layer 347 is formed on the peripheral area 345 and avoiding the plurality of first icon areas 341, the plurality of second icon areas 342, the plurality of third icon areas 343 and the operating window area 344, as shown in FIG. 7. As a result, the peripheral area 345 is covered by the cover lens opaque layer 346 and the light-proof layer 347, resulting in 100% light proof. The first icon areas 341, the second icon areas 342, and the third icon areas 343 are only covered by the cover lens opaque layer 346 without the light-proof layer 347, and therefore they are translucent with the opacity from 89% to 95% and results in the first icon pattern set 30, the second icon pattern set 31 and the third icon pattern set 33, respectively. The operating window area 344 is covered neither by the cover lens opaque layer 346 nor by the light-proof layer 347, and therefore it is transparent still. In such a manner, the first icon areas 341, the second icon areas 342 and the third icon areas 343 with the opacity from 89% to 95% are formed on the rear side 340 of the cover lens 34 of the panel module 3.
