DETAILED DESCRIPTION

The embodiments of the present disclosure will be described in detail with reference to drawings. Herein, the illustrative embodiments of the present disclosure and their description are intended to be illustrative of the present disclosure and are not to be construed as limiting the present disclosure.

The embodiments of the present disclosure provide an electronic device and a method for displaying, which will be described in detail below with reference to the drawings.

FIG. 2A is a schematic diagram illustrating a structure of an electronic device according to an example embodiment of the present disclosure. As shown in FIG. 2A, the electronic device at least includes a display screen 201 and a bezel 202. The bezel 202 surrounds sides of the display screen 201. The display screen 201 has four screen corners 2011, and the four screen corners 2011 are rounded. The bezel 202 has four sides. Any one of the four sides intersects two of another three sides of the four sides respectively and is in parallel with a further side of another three sides of the four sides to form four bezel corners 2021. The four bezel corners 2021 correspond to the four screen corners 2011 respectively, and the four bezel corners 2021 are rounded.

The four sides include a first side 2022, a second side 2023, a third side 2024 and a fourth side 2025. The first side 2022 is in parallel with the second side 2023. The third side 2024 is in parallel with the fourth side 2025. The first side 2022 intersects the third side 2024 and the fourth side 2025 respectively. The second side 2023 intersects the third side 2024 and the fourth side 2025 respectively.

The rounded corner refers to an arc-shaped corner formed by replacing the original angle of the corner with an arc tangent to the two sides of the original angle of the corner. As shown in FIG. 2B, O is a vertex of an angle ∠AOB, and lines OD and OE are two sides of the angle ∠AOB. An arc is tangent to lines AD and BE. Tangent points are points A and B. Therefore, the arc , and the lines AD and BE forms a rounded corner.

Original right-angle corners of the display screen 201 are cut into arc shapes respectively to form the four screen corners 2011. As shown in FIG. 2C, the display screen 201 has four right-angled corners originally. The four rounded corners 2011 are formed by cutting the four right-angled corners based on the arcs shown in FIG. 2C.

In addition, the process of cutting the display screen may be various, including a laser cutting process, a water cutting process, and the like, and this embodiment is not limited thereto.

As shown in FIG. 2A, the four screen corners 2011 correspond to the four bezel corners 2021 respectively, which specifically refers to that: an upper left corner of the display screen 201 corresponds to an upper left corner of the bezel 202, a lower left corner of the display screen 201 corresponds to a lower left corner of the bezel 202, an upper right corner of the display screen 201 corresponds to an upper right corner of the bezel 202, and a lower right corner of the display screen 201 corresponds to a lower right corner of the bezel 202.

In an embodiment of the present disclosure, a distance between vertexes of the screen corners 2011 and bezel corners 2021 corresponding to each other is not less than a preset distance.

The preset distance refers a minimum distance capable of protecting the screen centers adequately. It could be considered that when the distance between the vertexes is less than the preset distance, the width of the bezel outside of the screen corners is too small, such that the screen corners are susceptible to have abrasion.

The vertex of the rounded corner refers to a midpoint of the arc for forming the rounded corner, i.e. a point on the arc and with the same distance from the two ends of the arc. Taking the upper left corner as an example, an enlarged view of the screen corner 2011 and the bezel corner 2021 is shown in FIG. 2D. Points E and F are the vertexes of the bezel corner 2021 and the screen corner 2011, respectively. A distance L between the two vertices E and F is a specified distance which is not less than the preset distance.

Typically, the four screen corners of the display screen are all right-angled corners, the four bezel corners of the bezel are rounded corners, and the widths of the four sides of the bezel are determined by the respective specified distance between the vertexes of the screen corners and bezel corners corresponding to each other. However, in order to adequately protect each screen angle, each specified distance should not be less than the preset distance, which causes that the widths of the four sides of the bezel cannot be reduced unrestrictedly.

In the embodiment, the four screen corners 2011 of the display screen 201 are set to be rounded so that the vertices of the four screen corners 2011 are closer to the center of the display screen 201 while the size of the display screen 201 is guaranteed to be constant. Even if the widths of the four sides of the bezel are reduced, it is ensured that the specified distance between the vertex of the corresponding screen corner 2011 and the vertex of the corresponding bezel corner 2021 is not less than the preset distance, and the effect of protecting the display screen 201 may also be achieved.

It should be noted that the electronic device may be a smart phone, a television, a tablet, and the like, and the embodiment is not limited thereto.

With the electronic device provided by the embodiments, by setting the four screen corners of the display screen and the four bezel corners of the bezel to be the rounded corners, the vertexes of the four screen corners 2011 are closer to the center of the display screen 201 under a condition that the size of the display screen is constant, and the widths of the four sides of the bezel can be reduced under a condition that the specific distance between the vertexes of the bezel corners and screen corners corresponding to each other is not less than the preset distance, therefore narrowing the bezel of the electronic device. In addition, by configuring the rounded screen corners and the narrow bezel, the aesthetics of electronic equipment is enhanced greatly.

In a possible implementation, in order to enhance the aesthetics of electronic equipment, a curvature of each of the four screen corners 2011 is equal to a curvature of each of the four bezel corners 2021.

The curvature is configured to indicate a degree of bending of the arc. The greater the curvature, the greater the degree of bending of the arc is. The curvature of the arc is inversely proportional to the radius of the arc. In order to ensure that the curvature of a screen corner 2011 is equal to the curvature of a bezel corner 2021, it is needed to ensure the radius of an arc of the screen corner 2011 is equal to the radius of an arc of the bezel corner 2021.

As shown in FIG. 2E, O₁ is a center of a circle for the arc of the screen corner 2011 and O₂ is a center of a circle for the arc of the bezel corner 2021. The radiuses for the arc of the screen corner 2011 and for the arc of the bezel corner 2021 both are R₀, so the curvature of the screen corner 2011 is equal to the curvature of the bezel corner 2021.

In a possible implementation, a central angle of each of the four screen corners 2011 is equal to a central angle of each of the four bezel corners 2021.

For the arc, the central angle refers to an angle having a vertex as the center of the circle for the arc and having two lines passing through two ends of the arc. As shown in FIG. 2F, an arc is on a circle O₃, a point O₃ is the center of the circle, and the central angle corresponding to the arc is a central angle ∠GO₃I. The lines O₃G and O₃I of the central angle ∠GO₃I pass through two ends G and I of the arc respectively.

The central angle of each of the four screen corners 2011 is equal to the central angle of each of the four bezel corners 2021, which refers to that: the center of the circle for the arc of the corresponding screen corner 2011 is the same with the center of the circle for the arc of the corresponding bezel corner 2021, extension lines of two lines of the central angle for the corresponding screen corner 2011 are coincided with extension lines of two lines of the central angle for the corresponding bezel corner 2021 respectively. As shown in FIG. 2G the central angle for the corresponding screen corner 2011 and the central angle for the corresponding bezel corner 2021 both are ∠MO₄N.

In a possible implementation, the display screen 201 is a liquid crystal display screen. The liquid crystal display screen is provided with a plurality of pixel electrodes. In cutting the liquid crystal display screen, it is not necessary to provide a pixel electrode for the portion to be cut off on the liquid crystal display screen.

Alternatively, the display screen may be another type of display screen such as a plasma display screen, which is not limited in this embodiment.

All of the above alternative implementations may be used in any combination to form alternative embodiments of the present disclosure and are not further described herein.

FIG. 3A is a flow chart showing a display method according to an example embodiment of the present disclosure. As shown in FIG. 3A, the method is applied to the electronic device shown in FIG. 3B and includes followings.

In step 301, a preset floating layer is acquired. The preset floating layer includes a first portion and a second portion. The first portion is black, and the second portion is transparent. A dividing line between the first portion and the second portion is an arc-shaped smooth curve.

A length of the preset floating layer is equal to a length of the display screen, and a width of the preset floating layer is equal to a width of the display screen. The length of the display screen refers to the distance between the left side and the right side of the display screen, and the width of the display screen refers to the distance between the upper side and the lower side of the display screen. As shown in FIG. 3B, the display screen 201 has a length L1 and a width L2.

The preset floating layer may be provided in the electronic device by a technician, or, the preset floating layer may be created by the electronic device. For example, the electronic device can acquire the size information of the display screen, in which the size information includes the length and the width of the display screen, the radius and the arc length of each screen corner of the display screen, and the like; and then the electronic device can create the preset floating layer based on the size information such that the length and the width of the preset floating layer are equal to the length and the width of the display screen respectively, and divides the preset floating layer into two portions according to the radius and the arc length of each screen corner, and the like, in which the first portion is set as a black floating layer, and the second portion is set as a transparent floating layer so that the dividing line of the first portion and the second portion is the arc-shaped smooth curve and is located at the inner side of edges of the display screen. So when the preset floating layer is displayed, the first portion of the preset floating layer can cover the content displayed on the edges of the display screen.

The four angles of the preset floating layer may be the right-angles or rounded angles, and this embodiment is not limited thereto.

In a possible implementation, the dividing line is located on an inside of the edges of the rounded screen corners of the display screen.

As shown in FIG. 3C, taking the upper left corner as an example, when the upper left corner of the display screen 201 is cut into the rounded corner from the right-angled corner, the edge of the upper left corner is not smooth due to a limitation of the cutting process, such that a plurality of pixels on the edge of the upper left corner are formed as serrated. The edge of the page displayed may be not smooth when the display is performed by the display screen 201, affecting the user's observation. The dividing line between the first portion (denoted by the dotted line) and the second portion of the preset floating layer as shown in FIG. 3C is located at the inside of the serrated edges of the display screen. When the display screen displays the page, the first portion may obscure the content displayed at the serrated edges.

In step 302, when a page is displayed, the preset floating layer is displayed on a top of the page so that the first portion shades the page.

The preset floating layer can be set on the top by the electronic device. When the electronic device displays any page any time, the preset floating layer may be shown on the top of the page, thus ensuring that the first portion of the floating layer covers the region overlapped with the first portion on the page but does not cover the region overlapped with the second portion. The user can only see the region overlapped with the second portion when viewing the page, and the edges of this region are smooth.

As shown in FIG. 3D, the black region is the first portion, which can cover the saw-teeth at the rounded corners of the display screen as shown in FIG. 3C. The page saw by the user is located at the region of the second portion when the page is displayed, i.e. the region within the dividing line. The boundary of this region is the smooth curve, and the boundary of the page displayed to the user is also smooth.

When the page is displayed, the electronic device controls the pixels corresponding to first portion on the display screen to be black.

Since the size of the preset floating layer is in the accordance with the size of the display screen, and the preset floating layer and the display screen can correspond to each other, a part of the pixels on the display screen will correspond to the first portion and another part of the pixels on the display screen will correspond to the second portion. The pixels corresponding to the first portion on the display screen are located at outside of the dividing line of the preset floating layer.

In the embodiment, in order to ensure that the first portion obscures the displayed page, in actual operation, the electronic device can control the pixels corresponding to the first portion on the display screen to be black, that is, to control the brightness of these pixels to be 0, so as to block the page displayed on the edges of the four screen corners.

With the method provided in embodiments, the preset floating layer is acquired, in which the preset floating layer includes the first portion and the second portion, the first portion is the black floating layer, the second portion is the transparent floating layer, and the dividing line of the black floating layer and the transparent floating layer is the arc-shaped smooth curve; and the preset floating layer is displayed on the top of the page when the page is displayed, the black floating layer of the preset floating layer will block the rounded corners of the page and the not-smooth part on the displayed page is covered, so that the rounded corners on the page become smooth and the display effect is improved.

The edges of the display screen in the electronic device shown in FIG. 3A are not smooth. The screen corners after being cut are very rough due to the limitation of the cutting process when the four original right-angled corners are cut into the rounded corners. The pixels at the edges are box-shaped, resulting in the edges of the display screen are serrated and not smooth. When the page is to be displayed, the serrated edges of the display screen will be displayed, which will give the user a bad visual effect.

In order to eliminate the non-smoothness of the edges caused by the limitation of the cutting process, in the present embodiment, the preset floating layer is displayed on the top of the page, the preset floating layer is divided into two parts, one part is the black floating layer configured to hide a part on the page where the edges are not smooth, another part is the transparent floating layer configured to display the page, and the dividing line between the black floating layer and the transparent floating layer is the smooth curve, so the region overlapped with the second portion on the page may be displayed to the user and the edges of this region are smooth, thus solving the problem that the edges of the displayed page are not smooth.
