FIG. 1 shows a front perspective view of the electronic reading device 100 according to one or more aspects of the disclosed subject matter. Figure 8 is a diagram similar to Figure 1. The electronic reading device 100 (also referred to as the electronic reader 100, the electronic reader device 100, the device 100, etc.) is an electronic personal display used to read electronic books (eBooks), electronic magazines, and other digital content. For example, the digital content of an e-book is displayed as alphanumeric and/or graphic images on the display of an e-reader so that users can read the digital content in the same way as reading the analogous content of printed pages in a paper book . E-readers provide a convenient format to store, transport, and view a large number of digital content collections. These collections may occupy a lot of space if they are collected in traditional paper format.

In some examples, e-readers are purpose built devices designed to perform particularly well in displaying readable content. For example, the purpose of constructing an e-reader may include a display that reduces glare, performs well under high-light conditions, and/or mimics the appearance of text on real paper. Although an e-reader built for this purpose is good at displaying content for users to read, it can also perform other functions, such as displaying images, emitting audio, recording audio, and web browsing.

There are also many types of consumer devices that can receive services and resources from network services. Such a device can operate applications or provide other functions that link the device to a specific account of a specific service. For example, an e-reader device is typically connected to an online bookstore, and a multimedia playback device usually includes an application that allows users to access the online multimedia library. In this article, the user account allows the user to receive all the benefits and functions of the device.

According to an embodiment, the electronic reading device 100 can promote electronic reading activities. The electronic reading device 100 may include an electronic display device and a network service. Network services may include multiple servers and other computing resources, which provide various services related to one or more applications installed on the e-reader device. For example, in one implementation, a network service can provide an e-book service that communicates with an e-reader device. The e-book services provided through network services include, for example, the services of selling, sharing, downloading and/or storing e-books. Generally speaking, network services can provide a variety of other content services, including content presentation services (for example, streaming media) and other network application environments or services.

The e-reader device 100 can correspond to any electronic personal display device on which application programs and application program resources (for example, e-books, media files, documents) can be presented and used. For example, the e-reader device 100 can correspond to a tablet computer or a call/messaging device (for example, a smart phone). In one implementation, for example, the e-reader device 100 can run an e-reader application that connects the device to a network service and can enable the e-book provided through the service to be viewed and used. In another implementation, the e-reader device 100 can run a media playing or streaming application, which receives files or streaming files from a network service. For example, the e-reader device 100 may be equipped with hardware and software to optimize certain application activities, such as the presentation of electronic content (eg, e-books). For example, the e-reader device 100 may have a tablet-like form factor, although variations are possible. In some cases, the e-reader device 100 may also have an E-ink display.

The e-reader device 100 includes a housing, and the housing includes a display screen 104 on which text content from the selected e-book can be presented. The display screen 104 can be configured as a touch sensing component of the display unit, and input features are provided (or enabled in other ways) on it. In an exemplary embodiment, the display screen 104 is an 8-inch flexible display, such as a plastic-backed display. As can be seen from Figure 1, the housing has an asymmetrical design, in which the housing extends a relatively large distance from the display screen 104 on one side, which is due to the existence of the extended housing portion 118. In Figure 1, the extended housing portion 118 is located on the right side of the display screen 104. The housing has a first main surface 102 (that is, a front surface) and a second main surface 302 (that is, a rear surface, shown in FIG. 3). The housing also has a first edge 106 (that is, the right edge, shown in Figure 1), a second edge 108 (that is, the left edge, shown in Figure 1), and a third edge 110 (that is, the upper edge). , Shown in Figure 1), and the fourth edge 112 (that is, the lower edge, shown in Figure 1).

It can be seen from Figure 1 that the thickness of the shell gradually increases from the second edge 108 to the first edge 106. In an exemplary embodiment, the thickness of the shell in the extended shell portion 118 is uniform, and the thickness can be, for example, 8 to 11 mm. In an exemplary embodiment, the thickness of the shell in the extended shell portion 118 is 9.8 mm. The larger thickness of the shell in the extended shell portion 118 simulates the feel of a soft cover book with pages folded back. In an exemplary embodiment, the thickness of the shell in the extended shell portion 118 varies up to 10% non-uniformly. The thinnest part of the housing located closest to the second edge 108 may be, for example, 4 to 6 mm. In an exemplary embodiment, the thinnest part of the housing may be 5 mm +/- 0.5 mm (for example, 5 mm). In an exemplary embodiment, the distance between the third edge 110 and the fourth edge 112 may be 173 mm +/- 10 mm (for example, 173.1 mm). In an exemplary embodiment, the distance between the first edge 106 and the second edge 108 may be 156 mm +/- 10 mm (for example, 156.4 mm). The electronic reading device 100 can have a range of sizes to incorporate various hardware components. In an exemplary embodiment, the depth of the electronic reading device 100 may be less than seven millimeters. More specifically, the depth of the electronic reading device can be 6.99 mm.

It can be seen from Figure 7 that when the e-reader device 100 is placed on a flat surface, the second main surface 302 contacts the flat surface, because the housing in the area of the extended housing part 118 faces upwards From an angle, the e-reader device 100 can be easily picked up. The upward-angled hand grip in the extended housing portion 118 is designed to fit in the natural pocket formed by the user’s palm when the user’s hand is in a natural and relaxed gesture. The main ergonomic benefit designed for angled hand grips. In addition, the angled soft-touch painted hand grip of the extended housing portion 118 and the spacer 128 provide a natural thumb rest area, combined with the curved and textured back cover 1502, so that even Under long-term use, users can fix the electronic reading device 100 in their hands without increasing the pressure on their thumbs and fingers. Another ergonomic benefit is that since the electronic reading device 100 has an upward-angled hand grip feature, when the electronic reading device 100 is placed on a flat surface, it will be easily picked up. Similarly, the extended housing portion 118 may have rubber or another high friction surface treatment/material on the side of the first main surface 102, which provides good grip on the e-reader device 100.

The extended housing part 118 includes a first button 114 and a second button 116. As can be seen in Figure 11, the first button 114 and the second button 116 are raised and extended beyond the remaining surface of the extended housing portion 118. The first button 114 and the second button 116 are separated from each other by a distance member 128 (for example, a rectangular plastic member), and the distance may be the same as the length of the first button 114 or the second button 116. In an exemplary embodiment, the first button 114 and the second button 116 can be used to move the e-book forward or backward by one page, which will be described in detail later. The flush surface (spacer 128) between the first button 114 and the second button 116 provides a natural thumb rest area when the electronic reading device 100 is held while the page flip button is not in operation. As can be seen from Figure 8, the first button 114 and the second button 116 have long rectangular shapes, which are oriented along the vertical direction (that is, the buttons are parallel to the first edge 106). The first and second buttons 114, 116 extend a relatively long distance along the extended housing portion 118. The position, shape, and length of the first and second buttons 114, 116 provide a wide range of hand positions and prevent the user from fatigue.

As can be seen from Figure 1, the shell has four rounded corners 120, 122, 124, and 126, and the radius of the corners 120 and 122 (which are located in the extended shell portion 118) is larger than the corners 124 and 126 ( Located on the opposite side of the extended housing portion 118) of the housing.

As can be seen from Figures 2 and 9, the on/off button 202 is located on the first edge 106. In an exemplary embodiment, the on/off button 202 is located in the middle of the first edge 106, but the on/off button 202 can be located anywhere along the first edge 106. The on/off button 202 may have an oval shape, a rectangular shape, or any other shape. The on/off button 202 can be raised and extended beyond the surface of the first edge 106.

Figures 3 and 10 show the second main surface 302 (ie, the back cover/rear surface) of the e-reader device 100. The second main surface 302 can be made of plastic, and all or part of the plastic can be covered by rubber to protect the electronic reader device 100 from sliding.

Figures 4 and 11 show side views of the e-reader device 100 as viewed from the end of the device with the second edge 108. It can be seen from Figure 11 that the first button 114 and the second button 116 do not extend beyond the highest part of the extended housing portion 118. In other words, as shown in FIGS. 7 and 14, the uppermost surface of the first edge 106 is higher than the uppermost surface of the first button 114 and the uppermost surface of the second button 116.

Figures 5 and 12 show a side view of the e-reader device 100 viewed from the end of the device having the first edge 106. In an exemplary embodiment, the first edge 106 includes a charging port 502, which can be a USB port, a micro USB port, a FireWire port, or any other port that can be used for charging.

Figures 6 and 13 show a side view of the e-reader device 100 as viewed from the end of the device with the third edge 110. It can be seen from Figure 6 that the thickness of the e-reader device increases linearly from left to right (that is, from the second edge to the left side of the extended housing part 118). In Figures 6 and 13, the first main surface 102 with the display is located on the lower side of the drawing, and the second main surface 302 is located on the upper side of the drawing.

Figures 7 and 14 show a side view of the e-reader device 100 as viewed from the end of the device with the fourth edge 112. In Figures 7 and 14, the first main surface 102 with the display is located on the upper side of the drawing, and the second main surface 302 is located on the lower side of the drawing.

Fig. 15 is an exploded view (mechanical stacking) of the e-reader device 100 according to the illustrated embodiment. The components of the electronic reader device 100 include a back cover 1502, a middle frame component 1504, a display unit 1506, and a decorative board 1508. The back cover 1502 constitutes at least the second main surface 302. The back cover 1502 can be made of, for example, plastic, and has an in-molded micro-texture with a soft touch coating on its outer surface. The back cover 1502 can also be two-material injection molding, which includes shock-absorbing materials. The back cover 1502 of the e-reader device 100 may include various styles and predetermined patterns for aesthetic purposes, and provide gripping properties to assist in holding the e-reader device 100. The pattern may be cut by, for example, laser so that at least a part of the pattern includes a predetermined depth.

The middle frame component 1504 functions as a flexural material, and adds rigidity and strength to the electronic reader device 100. It can be seen from FIG. 15 that the middle frame assembly 1504 is located between the back cover 1502 and the display unit 1506. The middle frame assembly 1504 may be made of, for example, magnesium. The middle frame component 1504 is not limited to magnesium, and may be any other metal (for example, aluminum, titanium, etc.). In an exemplary embodiment, the middle frame component 1504 may be die-casting and co-molding. As can be seen from FIGS. 15-18, the middle frame component 1504 includes a first recessed portion 1512 configured to receive the battery 1804, and a second recessed portion 1510 configured to receive a printed circuit board (PCB) 1802. The middle frame component 1504 also includes a weight reduction part 1514. In an exemplary embodiment, the first recessed portion 1512 is rectangular in shape, and the battery 1804 can be held flush in the first recessed portion 1512. However, the first recessed portion 1512 can be any shape corresponding to the shape of the battery. In an exemplary embodiment, the first recessed portion 1512 is made of a continuous material so that it has no holes or perforated portions. Alternatively, the first recessed portion 1512 may contain a hole or a perforated portion 2010 to reduce weight. The middle frame component 1504 can increase the rigidity of the electronic reading device 100. Specifically, due to the thinness of the electronic reading device 100 (for example, 6.99 mm), the predetermined degree of rigidity is advantageous.

In an exemplary embodiment, the second recessed portion 1510 is rectangular in shape and includes a hole or perforated portion 2010 to reduce weight. However, the second recessed portion 1510 can be any shape corresponding to the shape of the PCB 1802. The hole 2010 can be circular, square, triangular, hexagonal, pentagonal, or any other shape in shape. The PCB 1802 can be held flush in the second recessed portion 1510. It can be seen from FIG. 15 that the weight reduction portion 1514 covers most of the area of the middle frame assembly 1504, excluding the first recessed portion 1512 and the second recessed portion 1510. The weight reduction portion 1514 may include a ribbed or lattice type structure, which increases the rigidity of the middle frame component 1504 at the thinnest point. Figure 15 shows the honeycomb-shaped rib structure. Since the perforated holes 2010 exist between the vertical rib patterns, it increases rigidity but also reduces weight. The middle rib structure is not limited to the honeycomb structure, instead, it can be made of any shape (triangular, pentagonal, etc.). On the opposite side of the middle frame assembly 1504 including the first recessed portion 1512 and the second recessed portion 1510, instead of a glass-backed display screen, the middle frame assembly 1504 can accept a plastic backed display screen. In this way, the electronic reading device 100 can be made thinner.

The display unit 1506 includes a display screen 104. The display screen 104 can be, for example, a flexible E Ink display, which is laminated with a touch panel and has a front light panel. The display screen 104 may also have an anti-glare cover lens.

The decoration board 1508 is a board placed on the upper portion of the display unit 1506 as seen in FIG. 19. The decorative board 1508 is insert-molded on the upper part with a pre-printed soft touch In-Mold Transfer (IMR) film. As can be seen from FIGS. 15 and 16, the lower side of the decorative board 1508 may include two or more magnets 1516. In an exemplary embodiment, the magnet 1516 is rectangular in shape. However, the magnet 1516 may be circular, square, or any other shape. The magnet 1516 in the decorative board 1508 can be used to interact with the corresponding magnet in the cover sheet (ie, the cover) for the electronic reader device 100 before protecting the accessory case. That is, the front cover sheet designed to protect the display screen 104 may have a position where it will be aligned with the magnet 1516 in the decorative plate 1508 when the cover sheet is in the closed position and is in contact with the display screen 104. magnet. When the e-reader device 100 is not in use, the magnet in the cover in front of the case and the magnet 1516 in the decorative board 1508 keep the front cover closed.

FIG. 17 is an exploded view (mechanical stacking) of the e-reader device 100 according to an exemplary embodiment, and is a different viewing angle from FIG. 15.

FIG. 18 is an exploded view (mechanical stacking) of the e-reader device 100 according to an exemplary embodiment, and is a different viewing angle from FIG. 15. Similarly, this drawing shows a middle frame assembly 1504 equipped with a battery 1804 and a PCB 1802. The display unit 1506 is assembled into the tray/recess 2002, which is located on the side of the middle frame assembly 1504, which cannot be seen from FIG. 18.

FIG. 19 is an exploded view (mechanical stacking) of the e-reader device 100 according to the illustrated embodiment, and is a different viewing angle from FIG. 15. Figure 19 shows that the display unit 1506 is tightly assembled into the tray/recess 2002 of the middle frame assembly 1504. Figure 19 also shows the button module 1902, which is a separate component from the decorative board 1508. The buttons of the button module 1902 are assembled inside the cutout part of the decorative board 1508. In an exemplary embodiment, the button module 1902 has two buttons, which are used to flip the page displayed on the e-reader device forward or backward. In addition to the two page buttons, the button module 1902 may have additional buttons for performing other designated functions.

Figures 20A, 20B, 20C, and 20D show different views/sides of the middle frame assembly 1504. As can be seen from figures 20A and 20C, the middle frame assembly 1504 has a first side 2004 which receives the display unit 1506. By raising the edge 2008 surrounding the periphery of the first side 2004, the display unit 1506 is held on the middle frame assembly 1504. As can be seen from Figures 20B and 20D, the middle frame component 1504 has a second side 2006, which includes a first recessed portion 1512 (ie, battery compartment) for receiving the battery 1804, and a second recessed portion for receiving the PCB 1802 1510 copies. The second side 2006 also includes one or more antenna compartments 2012. In an exemplary embodiment, there are two antenna compartments 2012. In an exemplary embodiment, each of the two antenna compartments 2012 is located at the corner of the middle frame assembly 1504. The raised boundary wall 2014 is formed as a partition between the first recessed portion 1512 and the second recessed portion 1510 and the weight saving portion with perforations/holes 2010.

The operations of the first and second buttons 114, 116 will now be described in detail. The first and second buttons 114, 116 can function as page flip buttons. If the e-reader device 100 is in the orientation shown in Figure 9, the user’s right hand is used to hold the e-reader device through the extended housing portion 118, and a single press of the second button 116 will cause it to be displayed The book/text advances one page. One press of the first button 114 will move the book/text back one page to the previous page. If the second button 116 is pressed, multiple pages will be advanced, and the longer the second button 116 is pressed, the page will advance faster. Similarly, if the first button 114 is pressed, multiple pages can be moved back, and the longer the first button 114 is pressed, the faster it can move to the previous page. When the first button 114 or the second button 116 is pressed (quick flip mode), data is captured so that the number of the flipped page can be stored by the electronic reader device 100. This information is important for determining, for example, whether students skip chapters in textbooks or other books.

In addition to using the buttons 114, 116 to turn pages up and down, these buttons can be used to control non-book scrolling. For example, if a web page is displayed with multiple pages, the buttons 114, 116 can be used to scroll the page up and down, and the user does not need to use his finger on the screen. In this way, the user can use one hand instead of two hands to hold and control the device. Similarly, when the e-reader device 100 is displaying the library of books (ie, e-reader library or bookshelf), the buttons 114 and 116 allow the user to turn the page up and down through the library of books. page. The buttons 114, 116 can also be used to scroll the displayed menu.

When viewing PDF files/images on the display screen 104, the buttons 114 and 116 can also be used. When the display screen 104 is displaying a PDF file/image that is less than the entire page, pressing the buttons 114, 116 causes the portion of the PDF currently being viewed to be changed instead of changing the page of the PDF file. In other words, the buttons 114, 116 allow you to flip between parts of the pages of the PDF file, instead of flipping to different pages in the PDF file. In this mode, buttons are used to move up and down subsections of the PDF page. For example, if the upper half of the PDF page is displayed and the lower half of the PDF page is not displayed, by pressing the lower button between buttons 114 and 116, the lower half of the PDF page will now be displayed, and The non-next page is displayed.

The functions of the buttons 114 and 116 are related to the orientation of the e-reader device 100, which is detected by an accelerometer. For example, when the e-reader device 100 is in the orientation where the user's left hand is holding the e-reader device 100 by the extended housing portion 118, pressing the second button 116 will allow based on which is being displayed Move to the previous page or pages or scroll up.

Based on the orientation of the e-reader device 100, the text/image on the display screen 104 has four different orientations, and regardless of the detected orientation based on the e-reader device 100, the buttons 114, 116 function as page up/up Scroll or page down/scroll down.

In an exemplary embodiment, the e-reader device 100 has a user-selectable screen rotation lock function. For example, the user can access a menu displayed on the display screen 104 for the user-selectable screen rotation lock function to start, and select an option that allows the screen to be locked in portrait orientation or landscape orientation. In an exemplary embodiment, when the screen is locked to the portrait mode and the user changes the hand holding the device 100 (causing the device to rotate 180 degrees), the screen will be automatically rotated 180 degrees and remain in the portrait mode. That is, the orientation of the image on the screen after the hand change will be the same as before. This line is shown in Figures 21A and 21C. When the screen is locked in portrait mode and held by the user's right hand (Figure 21A), the e-reader device 100 can be transformed to the user's left hand (Figure 21C), and the screen will still be in portrait mode. And the displayed screen will still have the same orientation before the hand change (the device rotates 180 degrees). When the device 100 is being rotated (see Figure 21B), the landscape orientation will not be displayed. Similarly, when the screen is locked to the landscape mode and the user changes the hand holding the device 100 (causing the device to rotate 180 degrees), the screen will be automatically rotated 180 degrees and remain in the landscape mode. When the device 100 is being rotated, the portrait orientation will not be displayed.

Figure 22 is a flowchart that further illustrates the screen rotation lock function that the user can select. In step S100, the user accesses the menu for starting the user-selectable screen rotation lock function. Next, in step S102, the user selects a menu option that provides the screen to be locked in portrait orientation (or landscape orientation). In step S104, the user rotates the screen 90 degrees while the screen stays in portrait orientation (or landscape orientation). In step S106, if the user rotates the screen another 90 degrees in the same direction as the previous rotation (for example, the device orientation in Figure 21B to the device orientation in Figure 21C), the screen is turned 180 degrees so that the screen is in Portrait orientation and the screen in the same orientation as before any rotation (ie, the original image orientation in Figure 21A).

When the screen rotation lock function is not being used and the e-reader device 100 is in automatic rotation mode and the user moves the device 100 from portrait orientation to landscape orientation (instead of the screen 104 immediately switching orientation), the user is asked if it is true The message that you want the screen 104 to be rotated is displayed. For example, if the user is lying on the bed and reading in portrait mode, he will not want the screen 104 to be converted to landscape mode. If the user moves the device 100 from landscape orientation to portrait orientation during the auto-rotation mode, a similar message is displayed. Therefore, with the user-selectable screen rotation lock function, the user can lock the screen to portrait mode (Figure 21A), and then when the user is lying on the bed to read, the screen will have the appropriate screen as shown in Figure 21B. Directional. When the user lies on his side and the screen is locked to portrait mode, the screen will not automatically switch to landscape mode.
