Description

Display screen and electronic equipment

Technical Field

The application relates to the field of electronic equipment with a display screen, in particular to a display screen and electronic equipment.

Background

Referring to fig. 1 and fig. 2, a conventional electronic device, such as a mobile phone, generally has a frame region 92 around a display region 91 of a display screen. These border regions 92 are typically formed with one or more through holes 921. A camera 93, a distance sensor, an ambient light sensor, and the like are mounted below the through hole 921. Thus, light above the display screen can pass through the through hole 921 to the camera 93 or the sensor installed below the through hole 921, and thus be captured by the camera 93 or the sensor.

Since components such as sensors and cameras 93 need to be mounted below the through holes in the bezel area 92, the bezel area 92 needs to have a certain width in order to accommodate these components, otherwise the components mounted therebelow would extend beyond the bottom housing of the entire electronic device. Therefore, this results in that the screen occupation ratio of the display screen (i.e., the proportion of the area occupied by the display region in the entire area of the display screen) is difficult to increase.

In addition, a camera in the electronic device generally has a zoom function to meet the photographing requirements of the user. In addition, electronic devices that can meet the requirements for high-power zoom, wide-angle photographing, and the like, are becoming more popular with users. In order to realize high power zooming and other functions, the optical assembly structure of the camera head can be very complex. For example, the optical assembly 931 shown in fig. 2, the lenses in the optical assembly 931 need to move up and down and cooperate with each other to achieve high power zooming functions. While conventional smartphones are thin and do not have sufficient thickness to accommodate these optical components 931. If the electronic device is required to have functions of high power zoom, wide angle, etc., the thickness of the electronic device as a whole or a part thereof increases.

Detailed Description

In a first embodiment of the present application, a display screen is provided. Referring to fig. 3 to 5, fig. 3 is a schematic top view structure diagram of an implementation manner of the display screen in the present application; FIG. 4 is a schematic side cross-sectional view of one implementation of a display screen and sensor assembly of the present application; fig. 5 is a schematic perspective view of one implementation of the display screen and the sensor assembly of the present application. The display panel 1 has a display area 11, at least one side of the display area 11 has a frame area 12, and at least one of the frame areas 12 has an opening 121. A sensor assembly is disposed below the display screen 1 and includes a reflective mirror 21 and a sensor 22. Wherein the reflective mirror 21 is disposed below the opening 121, the sensor 22 is disposed below the display area 11, and light entering from above the opening 121 to below the opening 121 enters the sensor 22 by being reflected by the reflective mirror 21, and is captured by the sensor 22.

The display screen 1 described above may be applied in an electronic device comprising a sensor assembly. Since the mirror 21 changes the path of light entering below the bezel area 12 through the opening 121, the sensor 22 can be disposed below the display area 11 having a large accommodation space. In this way, the sensor 22 does not need to be mounted directly below the opening 121, i.e., below the bezel area 12. Thus, even if the width of the bezel area 12 is narrow, there is no further concern that the sensor 22 will extend beyond the bottom housing of the electronic device. Based on this, the frame area 12 of the display screen 1 can be designed to be narrow, thereby contributing to an increase in the screen occupation ratio of the display screen.

Furthermore, when it is necessary to mount the optical assembly 23 having a complicated structure below the opening 121, since the mirror 21 changes the path of light, the complicated optical assembly 23 can be disposed in a lateral direction without being disposed in a longitudinal direction. Therefore, with the above-described configuration, even if a camera having a complicated optical assembly 23 is added to the electronic apparatus, the thickness of the entire electronic apparatus is not increased.

The sensor may include an image sensor, an ambient light sensor, a distance sensor, and the like, which are based on optics.

Alternatively, the Display screen may be an Organic Light-Emitting Diode (OLED) screen or a Liquid Crystal Display (LCD) screen. The display panel includes light-emitting pixels (not shown) arranged in an array, and the area corresponding to the light-emitting pixels is the display area 11 of the display panel 1.

The display screen and the display area may be rectangular, or may be in other shapes according to different application scenarios, such as a circle, an ellipse, a regular polygon, and so on. Generally, for electronic devices such as mobile phones and tablet computers, the display area may be rectangular. It should be noted that the rectangle herein includes a conventional rectangle, and a rectangle with a chamfer. The display area 11 shown in fig. 3 is, for example, rectangular, 2 corners of which have rounded corners. For another example, the display area 11 shown in fig. 6 is rectangular, and 4 corners thereof have rounded corners.

Alternatively, the rectangular display region 11 has a frame region 12 outside at least one long side 111, and the opening 121 described above may be provided in the frame region 12. When the opening is provided in the middle of the frame region 12, the opening 121 may be disposed at the waist of the display panel 1, as shown in fig. 6.

Alternatively, at least one short side 112 of the rectangular display area 11 has a frame area outside, and the opening 121 may be disposed in the frame area 12, as shown in fig. 3 and 8.

The opening may be rectangular, circular, semicircular, or other shapes. Note that, similarly to the display region, the rectangle here includes a conventional rectangle, and a rectangle having a chamfer.

Alternatively, when the display area 11 and the opening 121 are both rectangular, the directions of the display area 11 and the opening 121 may be the same or may not be the same. The long side 1211 of the opening is parallel to the long side 111 of the display area, and the short side 1212 of the opening is parallel to the short side 112 of the display area, and the display area 11 is aligned with the opening 121, as shown in fig. 6. In this case, if the user can take a self-photograph with the electronic apparatus, the direction of the opening coincides with the direction of an image that can be captured by the camera at the time of the self-photograph. Since the direction of the opening is consistent with the direction of the display area, the image collected by the camera can be adaptively displayed on the display area.

Referring to fig. 7, taking a mobile phone as an example, if the opening 121 is rectangular, it is vertically formed on the frame region 12 of the long side 111 of the display region of the mobile phone. If the user stands and holds the mobile phone for self-shooting, the image 8 acquired by the camera is vertical due to the fact that the opening 121 determines the visual angle of the camera, and the whole display area 11 just can display the image 8 fully.

It should be noted that, for the above-mentioned opening, the width of the opening, that is, the length of the short side 1212 of the opening, is strictly limited, so as to avoid that the frame region 12 where the opening 121 is located occupies too much area of the whole display screen 1, which leads to a decrease in the area of the display region 11 and thus to a decrease in the screen occupation ratio. The length of the opening, i.e., the length of the long side 1211 of the opening, may be longer. The opening 121 has a large extension space in the length direction, which is beneficial to the camera to realize wide-angle shooting.

Further alternatively, the aspect ratio of the opening 121 may be the same as or similar to the aspect ratio of the display area 11, so that the entire display area can be fully utilized as much as possible when displaying the image captured by the camera, and the image is convenient for the user to view.

The long side 1211 of the opening is not parallel to the long side 111 of the display area, and there is an angle therebetween, and the display area 11 does not correspond to the opening 121.

Alternatively, the long side 1211 of the opening may be parallel to the short side 112 of the display area, i.e. the angle α between the long side 1211 of the opening and the long side 111 of the display area is 90 °, as shown in fig. 8. At this time, if the user takes a self-timer picture using the electronic apparatus, the image 8 captured by the camera can be displayed only on a part of the display area 11, as shown in fig. 9.

Optionally, the angle α between the long side 1211 of the opening and the long side 111 of the display area may also be 0-40 °. For example, in the schematic structure shown in fig. 10, the angle α between the long side 1211 of the opening and the long side 111 of the display region is 8 °.

It should be noted that one or more openings may be formed in the frame region 12. When a plurality of openings are formed in the border region (as shown in fig. 10), a plurality of sets of sensor assemblies can be correspondingly disposed below the header.

Referring to fig. 4 and 5, in one implementation of the reflector, the reflector 21 may include a reflective surface that is angled 135 ° from horizontal. The sensor 22 is disposed on one side of the reflective surface and is disposed perpendicular to the display screen 1 so as to receive light reflected in a horizontal direction by the reflective surface.

Referring to fig. 11, in another implementation of the reflective mirror, the reflective mirror may include two reflective surfaces, where an angle between the first reflective surface 211 and a horizontal plane is 135 °, the second reflective surface 212 is opposite to and parallel to the first reflective surface 211, and an angle between the second reflective surface 212 and the horizontal plane is 45 °. The sensor 22 is disposed below the second light reflecting surface 212 and is disposed parallel to the display screen 1 so as to receive the light reflected by the second light reflecting surface 212 in the vertical direction.

When the length of the sensor is too long, if the sensor is disposed perpendicular to the display screen, the thickness of the electronic device may be increased due to the too long length of the sensor. Therefore, the sensor can be still arranged in parallel with the display screen by adding the second reflecting surface, and the increase of the thickness of the electronic equipment caused by the overlong length of the sensor is avoided. In addition, the sensor can be arranged in a wider space below the display area after the light path is changed, and the problems that the space is narrow and the sensor cannot be installed when the sensor is arranged at the edge are avoided.

When the sensor 22 is an image sensor, an optical component 23 is further disposed between the sensor 22 and the reflective mirror 21, as shown in fig. 4, 5, and 11. The optical assembly 23 may include one or more lenses, which are not limited in this application. At this time, the combination of the optical assembly and the image sensor may also be referred to as a camera. Referring to fig. 12a and 12b, when the sensor 22 is a distance sensor or an ambient light sensor, no optical component may be disposed between the sensor 22 and the reflective mirror (in fig. 12a and 12b, the first reflective surface 211 and the second reflective surface 212), and the sensor 22 may receive or emit light directly through the reflective mirror.

Alternatively, referring to fig. 13, a convex lens 3 is disposed above the reflective mirror (the first reflective surface 211 in fig. 13). The convex lens 3 may be used to focus the light, thereby increasing the intensity of the light that can be captured by the sensor 22, reducing the thickness of the overall sensor 22 assembly. The convex lens 3 may be provided above the opening 121 or below the opening 121.

Optionally, referring to fig. 4 and fig. 11 to 13, the display screen 1 further includes a transparent screen cover 13, and the screen cover 13 covers the display area 11 and the frame area 12, so as to perform the functions of isolation and protection.

When the convex lens is arranged above the reflector and the screen cover plate covers the display area and the frame area, the convex lens is arranged above or below the opening and is of an independent structure, and certain difficulty exists in processing and using the convex lens. First, since the size of the convex lens is small, it is difficult to fix it above or below the screen cover. Secondly, even if can fix convex lens, inevitably can have a layer air bed between it and the screen apron, this air bed can carry out scattering, reflection and refraction to the light that is about to get into the opening or has got into the opening, and then influences the light capture effect of sensor. In addition, if a relative displacement occurs between the convex lens and the screen cover plate, the screen cover plate may be scratched, and the light transmission effect of the screen cover plate is affected.

Based on this, this application still provides a scheme, carries out institutional advancement to the screen apron promptly to make the screen apron can realize convex lens's effect simultaneously, in order to avoid appearing above-mentioned problem.

In one implementation, referring to fig. 14 and 15, the area of the screen cover 13 above the opening 121 is protruded upward or downward to form the aforementioned convex lens 3. At this time, the convex lens 3 is integrally formed with the screen cover 13. When upwardly protruded, the structure of the screen cover 13 is as shown in fig. 14. When the screen cover 13 is downwardly protruded, the structure of the screen cover is as shown in fig. 15. When protruding downwards, convex lens 3 can be hidden at the one side of screen cover plate 13 that faces away from the user, avoids causing the influence to the one side of screen cover plate 13 that faces towards the user, brings the inconvenience for the user.

In another implementation, referring to fig. 16, the area of the screen cover 13 above the opening 121 is cut to form the aforementioned convex lens 3. The implementation mode is more convenient for industrial processing.

Generally, the edges of the screen cover are chamfered to prevent sharp corners from scratching users. Since the aforementioned openings are usually formed on the frame, very close to the edge of the display screen, if the upper side of the opening just corresponds to the chamfered area of the screen cover, the path of the light entering the opening will be affected.

In the embodiments of the present application, an edge of an area of the screen cover plate located above the opening is referred to as a first edge. The chamfer generally provided on the first edge may be referred to as a second chamfer. In order to avoid the aforementioned situation that the second chamfer affects the light path, in one implementation, a local edge of the first edge of the screen cover plate corresponding to the opening is not provided with a chamfer. In another implementation, referring to fig. 17, a first chamfer 132 is formed on a partial edge of the first edge 131 of the screen cover 13 corresponding to the opening. Wherein the size of the first chamfer 132 is much smaller than the size of the convex lens and much smaller than the size of the second chamfer 133. Through such design, both can avoid the local edge fish tail user that corresponds with the opening, also avoid simultaneously seting up like second chamfer 133 great chamfer to avoid influencing the ray path.

It should be understood that the above-mentioned solution in which the first edge is not chamfered or the first edge is chamfered with a second chamfer having a smaller size can be adopted regardless of whether the convex lens is present independently of the screen cover or the convex lens is integrally formed with the screen cover.

Optionally, the frame region of the display screen may be a protruding table protruding from the display region, and the protruding table is provided with an opening for allowing light to pass through. Accordingly, referring to fig. 18, the screen cover 13 also has a protruding area 134 to cover the entire display screen 1.

In a second embodiment of the present application, an electronic device is also provided. Referring to fig. 3 to 18, the electronic device may include any one of the display screens described above. In addition, the electronic device further comprises any one of the sensor assemblies described above. The sensor assembly comprises a reflector and a sensor, and the reflector is arranged below an opening in a frame of the display screen. The sensor is arranged on one side of the reflector, and light rays entering the lower portion of the opening from the upper portion of the opening enter the sensor after being reflected by the reflector. The sensor assembly herein may refer to any one of the sensor assemblies in the first embodiment, and will not be described herein.

Since the electronic device in this embodiment includes any one of the display screens in the first embodiment, the electronic device accordingly has the beneficial effects of the display screen in the first embodiment, and details are not repeated here.
