Please refer to FIG. 2, which is a functional block diagram of a portable device according to an embodiment of the invention. The portable device 200 includes a display screen 250, a determination unit 231, and an execution unit 232. The display screen 250 is used to display an icon and includes an infrared light receiving module 260. The infrared light receiving module 260 is disposed on the back side of the display screen 250 for receiving the infrared light beam R and obtaining the beam coordinate value of the infrared light beam R that is incident on the display screen 250. The determining unit 231 receives the aforementioned beam coordinate value and determines whether the beam coordinate value falls within a display coordinate value range of the icon. The executing unit 232 is configured to execute an icon clicking process when the determining unit 231 determines that the beam coordinate value falls within the display coordinate value range. In practical applications, the determining unit 231 and the executing unit 232 can be integrated into the processing chip 230 of the portable device 200.

In addition, the display device 250 further includes a stylus 290 for quickly and accurately operating the portable device 200. In one embodiment, the stylus 290 includes an infrared beam emitter 291 for emitting an infrared beam R. In addition to using the stylus 290, the user can operate the portable device 200 in direct contact with the display screen 250, and the infrared light beam R can be used to illuminate the display screen 250 to operate the portable device 200 in a non-contact manner.

Next, an operation method of the portable device 200 will be described. Please refer to FIG. 3, which is a flow chart of a method for operating a portable device according to an embodiment of the invention.

As shown in step S1, the operation method of the portable device 200 of the present embodiment first activates the infrared light receiving function of the display screen 250. In practical applications, the infrared light receiving module 260 can be activated by operating a function menu of the portable device 200 or by executing a specific program. In this embodiment, a shooting game program is executed as an example for description. When the shooting game program is launched, the portable device 200 activates the infrared light receiving module 260 to receive the infrared light beam R.

As shown in step S2, the operation method of this embodiment is followed by displaying an icon using the display screen 250. Please refer to FIG. 4A, which is a schematic diagram showing the display screen when the icon is displayed. In this embodiment, the icon P is a to-be-shot object, such as a flying disc. The icon P has a display coordinate value range on the display screen 250 for indicating the position of the icon P on the display screen 250.

After the portable device 200 displays the icon P via the display screen 250, the icon P can then be moved on the display screen 250 such that the icon P changes position to change its display coordinate value range over time.

As shown in step S3, the infrared light beam R is then emitted toward the display screen 250. Please refer to FIG. 4B, which shows a schematic diagram of the infrared light beam being irradiated on the display screen. In the portable device 200 of the embodiment, the infrared beam R is emitted by the infrared beam emitter 291 of the stylus 290, and the infrared beam R is irradiated onto the display screen 250.

As shown in step S4, the infrared light beam R is received using the display screen 250. In practical applications, when the infrared light beam R is incident on the display screen 250, the infrared light beam R passes through the display screen 250 and is irradiated to the infrared light receiving module 260 disposed on the back side of the display screen 250. The infrared light receiving module 260 receives the infrared light beam R and obtains the beam coordinate value of the infrared light beam R. After the beam coordinate value is obtained, the judging unit 231 continuously compares whether the beam coordinate value falls within the display coordinate value range of the icon P.

As shown in step S5, when the judging unit 231 judges that the beam coordinate value of the infrared light beam R falls within the display coordinate value range of the icon P, the executing unit 232 executes an icon clicking program. Please refer to FIG. 4C, which is a schematic diagram showing the infrared light beam illuminating the icon. In practical applications, when the beam coordinate value falls within the range of the display coordinate value, the infrared light beam R is illuminated on the icon P. For the shooting game program, it is equivalent to hitting the icon P. At this time, the executing unit 232 executes an icon clicking program, and displays a screen, such as a screen in which the frisbee is broken or exploded, by using the display screen 250, and then removes the icon P from the display screen 250.

Next, the operation method of the embodiment can display another icon P using the display screen 250. Similarly, when the beam coordinate value falls within another display coordinate value range of the other icon P, an icon click program is executed to display the hit image of the other icon P, and the word display screen 250 is removed. This other icon P.

In another embodiment, a plurality of icons P are simultaneously displayed on the display screen 250, and each of the icons P has a corresponding range of display coordinate values. When the beam coordinate value falls within one of the display coordinate value ranges, the execution unit 232 performs an icon click program to remove the icon P corresponding to the range of coordinate values displayed from the display screen 250.

In the portable device 200 according to the embodiment of the present invention, the shooting game program is executed and the operation is performed by using the stylus pen 290. In another embodiment, when the power is turned on, the portable device 200 activates the infrared light receiving function of the display screen 250. The icon P displayed on the display screen 250 is a function diagram, for example, a diagram representing a phone book or a text message. When the beam coordinate value falls within the display coordinate value range of the icon P, for the portable device 200, the icon P is equivalent to the user. At this time, the executing unit 232 executes an icon clicking program to start an application corresponding to one of the icons P.

On the other hand, the portable device 200 of the present embodiment is not limited to the operation of the stylus pen 290, and other components that can emit the infrared light beam R, such as a laser pen for presentation, can apply the infrared beam emitted by the laser beam. R operates the portable device 200.

The portable device and the operating method thereof according to the embodiments of the present invention use the infrared light beam to illuminate the display screen to operate the portable device in a non-contact manner, which can provide a more intuitive operation mode and improve the convenience of operation. Moreover, since the display screen or the button does not need to be touched when the portable device is operated, the problem that the display screen is scratched and the button is stripped can be avoided.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
