In addition, the electronic device 102 can be connected to the digital sticky note 104 through a wireless transmission interface 106 , such as an infrared transmission interface or a Bluetooth transmission interface. More specifically, the digital post-it note 104 can be realized by using a display.

Fig. 2 is a circuit block diagram of a digital post-it note according to a preferred embodiment of the present invention. Please refer to FIG. 2 , the digital post-it note 104 provided by this embodiment can be adapted to be realized by using an electronic paper display, and it has a substrate 200 , which is a flexible substrate, but is not limited thereto. In this embodiment, there is an attachment area on the substrate 200 , and a back-adhesive material is coated in the attachment area. In this way, the digital post-it note 104 can be repeatedly pasted on at least one surface.

In some other embodiments, other designs can also be used to replace the adhesive material, so that the digital sticky note 104 can be fixed and repeatedly fixed on a surface. For example, magnets can be used instead of the adhesive backing material. In addition, a clip structure can also be designed on the substrate 200, so that the digital sticky note 104 can be clipped on an object.

Please continue to refer to FIG. 2 , on the substrate 200 , a display array 202 is disposed, which can utilize electronic ink technology. Therefore, the display array 202 can continuously display images without power supply. In some embodiments, the display array 202 is realized by arranging a plurality of electrophoretic cells into an array.

In addition, the substrate 200 further includes a wireless receiving module 204 , a processing unit 206 and a display circuit 208 . The wireless receiving module 204, such as an infrared receiving module or a Bluetooth receiving module, can be connected with the electronic device 102 through, for example, the wireless transmission interface 106 in FIG. 1 .
