The present invention relates to an integrated circuit (IC) module having a display device, and more particularly to an IC module having display device powered by an electromagnetic induction device.
To keep abreast with constant evolvement of information technology, demands of users toward data storage seem to be an endless pursuit. In addition to data storage devices complying with the requirement of being light, thin, short and compact, storage capacity has also migrated from the conventional 1.44 MB floppy diskette to large-capacity data storage device in gigabytes (GB). Although the storage capacity of the present data storage devices, e.g. flash drive, hard drive, DVD disc and so forth, has significantly upgraded, if the demand trend of users toward storage capacity is a concern, the issue of insufficient storage capacity will still inevitably bother users in the future. As far as operational habit is concerned, users normally connect data storage devices to a power supply device, e.g. computer equipment, and confirm the capacity of data storage device only after the power is on. After the capacity is confirmed, users can then determine if the capacity is sufficient for users to store data. Such process not only results in users' inconvenience but also wastes energy. Hence, how to confirm the capacity of data storage devices conveniently, quickly and easily and save energy is indeed a critical subject.
Speaking of common energy in use, power supply device of computer equipment is one of those usually adopted to charge the rechargeable battery inside electronic products. Nowadays, a series of energy-saving solutions emerge one after the other as a result of the influence of energy conservation, and solar charging is one solution among them. However, solar charging is prone to environmental influence, leading to be inconvenient in operation, because solar charger may provide sufficient power in a sunny occasion and poor power in a dark occasion. Therefore, how to provide a stable power supply device could be a very critical issue.
To solve the foregoing issue, a main objective of the present invention is to provide an IC module having a display device in which a power supply device thereof capable of generating power by electromagnetic induction is electrically connected with the IC module and the display panel. Given the aforementioned components, when the IC module having the display device is shaken back and forth, the power supply device generates power, and the display panel displays information in association with the IC module after acquiring power, thereby providing information relevant to capacity and the like of the IC module in a convenient, fast and simple fashion to users.
Another objective of the present invention is to provide an IC module having a display device that a power supply device thereof capable of generating power by electromagnetic induction is electrically connected with the IC module and the display panel. Given the aforementioned components, when the IC module having the display device is shaken back and forth, the power supply device generates power and the display panel displays information in association with the IC module after acquiring power. As the present invention does not require the power supply of other power supply device such as computer equipment, the power-saving efficacy can be also achieved.
