Referring to Figures 9A and 9B, the level L1 forms the uppermost layer of the control module 60 and has a transparent window group, wherein the transparent window 1-9 is shown in Figure 9A. Transparent windows other than transparent windows 1-9 are shown in similar unnumbered squares in Figures 9B-9D. The transparent window of level L2 aligns with the transparent window of level L1. The transparent window of level L3 aligns the transparent windows of levels L2 and L4. Fig. 9F shows the light-emitting device of the hierarchy L4 in a similar circle, wherein the light-emitting devices 11-19 are shown in Fig. 9A. The windows of the levels L1-L3 can be filled with a transparent dielectric material so that the illumination means of the level L4 can be illuminated through these transparent windows.

Figure 9C shows the upper surface of the level L2. The layer L2 includes a printed circuit board (PCB), three metal planar regions 81-83 (shown in FIG. 9C) are formed thereon in a printed manner, and each metal planar region serves as a detection panel. electrode. There are multiple cutouts in each of the metal planar regions to form a plurality of windows. The through holes 91, 92, and 93 in the layer L2 indicated by dots in FIG. 9C are formed on the detecting plates 81-83, respectively, and filled with a conductive material. The bus bars 811, 821, and 831 of the connection detecting plates 81-83 are on the lower surface of the level L2, and thus are indicated by broken lines in Fig. 9C.

2, GUI control method

The electronic reading device 100 can provide a plurality of functions and display icons corresponding to a plurality of functions.

2.1 Graphic status

The state shown shows the events received or generated by the program combined with the illustration. When the display 155 is turned off or another program in the foreground is displayed, the processor 151 may update the state of the icon displayed by the illuminator of the physical control module 60 for synchronization with the associated program event or state of the illustration. .

The illustrated state can include at least three states, such as ON, OFF, and animation. The illustrated open state may include a plurality of sub-states for respectively representing the program function states to which the illustrations are combined. For example, a secondary state can indicate performing or pausing a function, logging in or logging out of a service, connecting or disconnecting a channel, and other events. The illustrated closed state shows that the electronic reading device 100 is in the pause mode. The animated status shown shows the icon related function or program sending a message.

Referring to FIG. 10, the icons 41-45 correspond to the following functions: returning to the main page, displaying the favorite folder (commonly referred to as "my favorite"), starting the music player, and simply collecting syndication (referred to as simple simple syndication). RSS) readers, as well as instant internet messaging applications. The illustrations 431-435 correspond to the option functions of the music player shown in Fig. 43, respectively. Diagram 431 corresponds to the pause and resume function of music playback. The illustrations 432 and 433 respectively correspond to the backward and forward operation of the music playback. Diagram 434 corresponds to displaying the functionality of the information query GUI. Diagram 435 corresponds to the function of displaying the player setting GUI. When it is detected that the touch operation activates one of the icons shown in FIG. 10, the processor 151 performs a function corresponding to the actuated icon.

Referring to Figure 10, regions 51-53 on physical control module 60 are in the vicinity of detection panels 81-83, respectively. Each of the regions 51-53 serves as an operating point of the physical control module 60, which, when actuated, drives the electronic reading device 100 to perform the functions associated with the operating point. The controller 165 can detect the touch when detecting the touch operation at the operation point. The control operation is interpreted as the actuation of the operating point. Each zone 51-53 may initially be uncoupled from any function, and the illuminators in zones 51-53 may initially be in a closed state without displaying any graphical images.

2.2 Example Operation

Referring to FIG. 11, the processor 151 detects a drag operation that moves an icon to a specific position on the edge of the display 155, the specific position is adjacent to an operation position of the entity control module 60 (step S2), and the operation position. The actuation event immediately follows the first drag operation (step S4). The processor 151 responds to steps S2 and S4, adds a picture to a reserved area of the main memory 152 (step S6), and combines the operation position with the function associated with the above illustration (step S8), and operates the position area. A portion of the illuminator is turned on to display a pictorial image for representing the icon at the operational position (step S10). Before step S2, if the operating position has been associated with another original icon and its original function, the processor 151 associates the associated substitute operating position generated in step S8 with the original icon and its original function. The processor 151 can represent the association as data and store it in the main memory 152 or the non-volatile memory 153.

If the drag operation is detected at the end of the display 155 (step S2), the elapsed time until the actuation event of the operational position occurs does not exceed the predetermined length of time D, the processor 151 may determine the actuation event of the operational position. It is immediately after the drag operation. If the end of the drag operation on the edge of the display 155 is within the proximity of one of the operational positions, the processor 151 may determine that the illustrated drag operation is a special drag operation. After the drag operation, the processor 151 displays the graphical image as a copy of the illustration and may not need to delete the icon in the display 155. Referring to FIG. 12, when an actuation event of an operation position is received (step S12), the processor 151 interprets the actuation event as an illustrated actuation event in conjunction with the operation position (step S14), and The function combined with the illustration is executed (step S16). It is to be understood that in step S12, the actuation event of the operating position does not immediately follow the special drag operation. The processor 151 updates the graphical image at the actuated operational position to synchronize the appearance of the image with the representation.

Referring to FIG. 10, for example, the processor 151 detects a first drag operation 201 that moves the icon 431 to a specific position P1 on the edge of the display 155, and the specific position P1 is adjacent to an operation area 51 of the entity control module 60 (step S2), and the operation area 51 is actuated immediately after the drag operation (step S4).
