[0034] The embodiment of the utility model discloses a handheld device and an eyepiece assembly thereof, so as to enhance the user experience when observing the display screen of the handheld device.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The handheld device provided in this application includes but is not limited to a binocular handheld device, and the eyepiece assembly is applicable to but not limited to a binocular handheld device. Taking binoculars as an example, the built-in display screens of binoculars currently on the market are mostly square screens with an aspect ratio of 4:3, which is not good for binocular viewing.

[0037] The human eye's visual system has a unique range of viewing angles: the overlapping field of view of the two eyes is 124 degrees, and the comfortable field of view of one eye is 60 degrees. Therefore, the field of view that the human eye can observe far exceeds the traditional flat field of view. It is actually a circular plane exceeding 180 degrees, similar to the field of view of a circular movie screen. This viewing angle range allows the human eye to obtain a sense of three-dimensionality when observing objects, especially when the objects are located within the 124-degree field of view that overlaps the two eyes. In addition, the human eye's comfortable field of view for one eye is 60 degrees, which means that only objects within this range can be clearly focused and seen by the human eye. The part outside this range, that is, the peripheral area beyond 30 degrees from the point of gaze, is called peripheral vision. Although it belongs to the peripheral vision range of the eye, the human eye is less sensitive to this part, which means that it cannot be seen clearly.

[0038] In the horizontal visual field: the binocular area is approximately within 60°, the most sensitive vision of the human eye is within 1° on each side of the standard line of sight, and the monocular standard line of sight is 94°~104° on each side.

[0039] In the vertical plane field of view: the maximum visual area is 70° below the standard line of sight, and the color discrimination limit is 30° above the standard line of sight and 40° below the standard line of sight.

[0040] In film and television, the human eye's perception of the screen has a significant impact on the choice of aspect ratio. Early film screens had an aspect ratio of 4:3, but this was gradually replaced by wider ratios in the early 20th century. In 1932, the Academy of Motion Picture Arts and Sciences voted to adopt an aspect ratio of 1.375, known as the Academy Ratio. Others believe this ratio was determined by calculating the horizontal and vertical range of the human eye to ensure that the aspect ratio corresponds to the human eye's perceptible range. 2 In the 1950s, with the rise of television, the film industry began exploring different aspect ratios to adapt to the new medium. For example, the 1952 promotional film "This Is Cinemascope" used a 2.59:1 aspect ratio, sparking a debate over widescreen within the industry.

[0041] In summary, the observation ratio of the human eye has a profound impact on the choice of screen ratios for visual media such as movies and television, and the 16:9 ratio is considered to be one of the standards that is closest to the natural observation ratio of the human eye.

[0042] However, during the development of this application, the inventors discovered that most high-definition movies are in 16:9 format. A 16:9 screen, when used for watching movies, eliminates the extra black edges, making a 16:9 screen a better choice. For office use, a 16:10 screen is more optimal. A 16:10 screen can display more content, is more versatile, offers a more comfortable viewing experience, and provides a wider field of view.

[0043] In addition, when observing through the eyepiece of a traditional eyepiece assembly, not only the display screen is within the user's field of view, but also the structural components outside the display screen are within the field of view. Therefore, the information observed by the user is very messy, which greatly interferes with the human eye's acquisition of main information.

[0044] In order to at least partially solve the defects of the above-mentioned handheld device, the present application provides a handheld device and its eyepiece assembly, by adding a light-shielding cover between the eyepiece and the display screen, and a window is provided on the cover. The effective display area of the display screen is the area directly facing the window. The shape and size of the window are set to provide a more comfortable viewing experience.

[0045] In some embodiments, see Figure 1-Figure 2 The eyepiece assembly of the handheld device provided by the present invention includes an eyepiece 1, a display screen 2, and a cover plate 3. The display screen 2 is located in front of the eyepiece 1. It should be understood that the term "front" herein refers to the side facing away from the user when viewing. That is, the display screen 2 is located on the side of the eyepiece 1 facing away from the user, and the user can observe the image displayed on the display screen 2 through the eyepiece 1. The specific structure of the eyepiece 1 can be referenced to the relevant configuration of the eyepiece 1 in conventional handheld devices and will not be further described here.

[0046] The cover plate 3 is disposed between the eyepiece 1 and the display screen 2. The cover plate 3 includes a window 31 and a light shield 32. At least a portion of the window 31 is curved. That is, at least a portion of the edge line of the window 31 is curved, meaning that the shape of the window 31 is different from the rectangular shape of the conventional display screen 2. The curved portion of the window 31 can specifically correspond to at least one short side of the rectangle, and preferably, the two opposing short sides of the window 31 are both curved. The projection of the window 31 on the display screen 2 is located within the display area of the display screen 2. Therefore, the portion of the display area facing the window 31 can be effectively displayed. That is, the human eye can only observe the display area on the display screen 2 facing the window 31 through the eyepiece 1. The light shield 32 is made of a light-shielding material and is disposed on the periphery of the window 31. It is understood that the light shield 32 can serve as part of the cover plate 3, such as the portion of the cover plate 3 facing the display area of the display screen 2 forming the light shield 32. Alternatively, the shading plate 32 may also serve as the integral cover plate 3 . Both methods can shield the portion of the display screen 2 except for the required effective display area, thereby forming a closed shading environment.

[0047] The eyepiece assembly of the handheld device provided by the present invention is provided with a cover plate 3 between the eyepiece 1 and the display screen 2, and the cover plate 3 includes a window 31 and a shading plate 32. The shading plate 32 can shield the portion of the display opposite to it. When the user observes through the eyepiece 1, the effective observation area is the area limited by the window 31, and at least part of the window 31 is arc-shaped, that is, the shading plate 32 blocks the display screen 2 to form an arc-shaped display effect, so it can better adapt to the user's observation habits and improve the comfort of human eye observation. In addition, the shading plate 32 can effectively shield the area outside the window 31, that is, realize a closed light-shielding environment and ensure the quality of optical imaging. The shading plate 32 effectively blocks the structure outside the display screen 2 exposed by the window 31, so that the information observed by the user is more concentrated, which is convenient for the human eye to obtain the main information. In summary, the eyepiece assembly provided by the present invention improves the user experience.

[0048] In some embodiments, see Figure 3 and Figure 4 The upper and lower ends of the window 31 are parallel and of equal length, while the left and right ends are convexly curved and symmetrical about the centerline of the window 31. It should be understood that the upper and lower ends of the window 31 refer to the upper and lower opposite ends of the window 31 when the user is normally observing the eyepiece 1, while the left and right ends refer to the left and right opposite ends of the window 31 when the user is normally observing the eyepiece 1. Specifically, the extending direction of the upper and lower ends corresponds to the length direction of the window 31. As configured above, the window 31 has a runway shape. The runway-shaped window 31 forms a runway-shaped effective display area, thereby presenting a curved runway effect that is comfortable for the human eye. When this eyepiece assembly is used in a binocular, the observation effect can be substantially consistent with that of a traditional telescope.

[0049] In some embodiments, the center of the window 31 is aligned with the center of the display screen 2. The effective display area defined by the window 31 coincides with the center of the display area of the display screen 2, further ensuring viewing comfort for the human eye.

[0050] In some embodiments, the aspect ratio of window 31 is 16:10. The effective display area defined by window 31 has a corresponding aspect ratio of 16:10, allowing for more content to be displayed on one screen, providing a more versatile and comfortable viewing experience, and offering the user a wider field of view. It will be appreciated that when window 31 is in a runway shape, the ratio between the maximum lengthwise distance between the left and right arcs of window 31 and the distance between the top and bottom arcs is 16:10.

[0051] In some embodiments, the display area of the display screen 2 includes an image display area 21 and a mask area 22. The image display area 21 is directly opposite the window 31, and the portion of the display screen 2 outside the image display area 21 is the mask area 22. In the aforementioned embodiments, a cover plate 3 is provided between the display screen 2 and the eyepiece 1, and the shape of the window 31 on the cover plate 3 defines the effective display area. This embodiment differs from the aforementioned embodiments in that the display screen 2 itself includes distinct display areas. The image display area 21 is directly opposite the window 31, forming the effective display area, while the rest of the display screen 2 is the mask area 22. The mask area 22 is not used for image display, but instead displays in another state, illustratively, black. When a user observes the display screen 2, the different partitions of the display screen 2 can also present a curved display that is comfortable for the human eye. In some specific examples, the mask area 22 is blocked by a light shield 32.

[0052] In some specific examples, the eyepiece assembly further includes a controller connected to the display screen 2. The controller includes an imaging display module and a black display module. The imaging display module is configured to display an image in an area directly opposite the window 31 on the display screen 2, and the black display module is configured to display black in other areas on the display screen 2. The specific display control principle can be referred to the display principle of a conventional display screen 2 and will not be described in detail here.

[0053] For example, the display screen 2 is an organic light emitting diode (OLED) display screen, and its resolution can adopt a conventional resolution of 1920*1080, such as Figure 5 As shown, the resolution of the video area is 1920*1000, and the bottom 80 pixels high is the status bar used to display the status of the handheld device. In addition, in order to solve the problem of unclear corner observation when used outdoors, and the 16:10 screen ratio is more versatile and more comfortable to watch, the display is divided into two partitions, such as Figure 6As shown, the resolution of the image display area 21 is 1600*1000, including the status bar with a height of 80 pixels at the bottom. The remaining area is the mask area 22. By superimposing a black arc mask on the entire display screen 2 interface, the aspect ratio is 16:10, thereby presenting a curved runway effect that is comfortable for human eyes to observe. Of course, in other optional embodiments, the mask area 22 can also be a normal display image, but it cannot be observed by the human eye because it is blocked, and the final effect observed by the human eye is also as follows. Figure 6 shown.

[0054] In some embodiments, see Figure 1 and Figure 7 The eyepiece assembly further includes a bracket 4, which is disposed in front of the eyepiece 1. The display screen 2 and the cover plate 3 are respectively disposed on the bracket 4. The bracket 4 is disposed on the side of the eyepiece 1 away from the user's viewing position. By providing the bracket 4, the display screen 2, the cover plate 3, and the bracket 4 are assembled into one body. When the handheld device is assembled, the whole body can be mounted on the housing of the handheld device, which is convenient to install and has high positioning accuracy.

[0055] In some embodiments, the bracket 4 is provided with a display screen mounting slot 41, within which the display screen 2 is positioned. A fixing portion 42 is provided on the bracket 4 outside the display screen mounting slot 41, and the cover plate 3 is connected to the fixing portion 42. The shape of the display screen mounting slot 41 can be configured accordingly to the shape of the display screen 2. The display screen mounting slot 41 serves to position the display screen 2. The connection between the cover plate 3 and the bracket 4 is located outside the display screen mounting slot 41, which not only avoids contact with the display screen 2 and fully utilizes the space, but also, the fixed connection between the cover plate 3 and the bracket 4 can restrict the display screen 2 within the display screen mounting slot 41, achieving reliable installation of the display screen 2 and the cover plate 3. The connection structure is simple and easy to assemble. Exemplarily, the fixing portion 42 is a bolt hole, and the cover plate 3 is bolted to the bracket 4.

[0056] In some embodiments, the cover plate 3 includes a cover plate body and two sliding plates. The cover plate body is provided with a through hole with parallel upper and lower ends. The opposing ends of the two sliding plates are each arc-shaped and convex outward. A window 31 is formed between the cover plate body and the two sliding plates. The cover plate body is mounted on a bracket 4. The two sliding plates are slidably mounted on the cover plate body, and the sliding directions of the two sliding plates are parallel to each other, so that the spacing between the two sliding plates can be adjusted. The cover plate 3 adopts a split structure. The two sliding plates cooperate with the through hole of the cover plate body to form a runway-shaped window 31. The two sliding plates can slide toward or away from each other, adjusting the size of the window 31 accordingly, thereby achieving different aspect ratios and providing more diverse display options for the eyepiece assembly. Users can select the appropriate aspect ratio display according to their needs. Specifically, a damping gasket can be provided between the two sliding plates and the cover plate body. The damping force of the damping gasket locks the two sliding plates at any position within their sliding travel, achieving continuously adjustable spacing.

[0057] Based on the eyepiece assembly provided in the above embodiments, the present invention further provides a handheld device, which includes any one of the eyepiece assemblies in the above embodiments. Since the handheld device adopts the eyepiece assembly in the above embodiments, the beneficial effects of the handheld device can be referred to the above embodiments.

[0058] Specifically, the handheld device is a binocular handheld device.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0060] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
