As a result, some pixels on the border may be blocked and may not be displayed completely. However, since each pixel is usually composed of three sub-pixels, such as red, green, and blue, when a pixel is not displayed completely, the proportion of the red, green, and blue sub-pixels of the pixel may change, resulting in a distorted pixel display, which in turn may cause color display distortion or jagged displays at the boundaries of the display area.

The present disclosure provides a display screen according to certain embodiments. The display screen may include a plurality of first pixels and at least one second pixel. Each of the first pixels may include at least three sub-pixels. The plurality of first pixels may constitute a display area of the display screen. Each of the second pixels may include at least three sub-pixels. The arrangement of the three sub-pixels of the second pixel may be different from the arrangement of the three sub-pixels of the first pixel. The at least one second pixel may be located at an edge of the display area. The plurality of first pixels and the at least one second pixel may constitute a pixel array of the display screen.
The present disclosure also provides an electronic device including the display screen according to certain embodiments. The electronic device may include a processor. The processor may be configured to display content on the display screen.
According to certain embodiments of the present disclosure, the pixel array in the display screen may include a first pixel and a second pixel. An arrangement of three sub-pixels of the second pixel may be different from an arrangement of three sub-pixels of the first pixel. A plurality of first pixels may constitute a display area of the display screen. At least one second pixel may be located at the display edge region. If the edge of the display area includes a curved portion, the arrangement manner of three sub-pixels in the second pixel may be determined according to a shape or direction of the curved portion. When the edge of the curved portion of the display area is formed by occluding a portion of the second pixel, the areas of the three un-occluded sub-pixels in the second pixel may to be equal, which may somewhat avoid color distortion or jagged edges at the edges of the curved portion in existing technology.
As shown in
Specifically, the display screen 20a of the electronic device 100a is a full screen. The four corners of the display screen 20a are rounded, including two upper rounded corners C1 and two lower rounded corners C2. The display screen 20b of the electronic device 100a is a notch display screen. The edges of the display screen 20b include curved portions, which are two upper rounded corners C1, two lower rounded corners C2, and two notch corners C3. The display screen 20c of the electronic device 200c is a cut-out screen. The edges of the display screen 20c include edges of curved portions, including two upper rounded corners C1, two lower rounded corners C2, and a circle C4 around the front camera.
In semiconductor processing, a single pixel is usually rectangular, and a large number of rectangular pixels form a pixel array of a display screen. To form the edges of the smooth curve shown in C1-C4 in
In an RGB color mode, a single pixel may include three sub-pixels of red R, green G, and blue B. The size of the area occupied by three sub-pixels in a pixel may be identical. However, when each pixel is partially occluded at the edge of the curved portion shown by C1-C4, the area ratio of three sub-pixels in the un-occluded portion may be affected. If the areas of the three sub-pixels in the un-occluded portion have a significant difference, it will cause color distortion at the edges of the curved portion shown by C1-C4. To address this problem, according to certain embodiments, the pixels disposed at the edge portion of the curves shown as C1-C4 may be configured as second pixels. The arrangement of the three sub-pixels of the second pixels may correspond to the curve portions C1-C4, which may make the un-occluded areas of the three sub-pixels in the second pixel equal to teach other. Thus, it is possible to effectively reduce the degree of color distortion at the edges of the curved portions similar to those shown by C1-C4.
It should be noted that
As shown in
According to certain embodiments of the present disclosure, the display screen 20 may further include a transparent cover plate 22. An inner surface of the transparent cover plate 22 may have a light-blocking region 221. A boundary between the light-blocking region 221 and the remaining region 222 of the transparent cover plate 22 may include at least one curved portion. The transparent cover plate 22 may be located above the pixel array 21. The curved portion of the boundary pixels of the pixel array 21 correspond to second pixels 212. The light-blocking region 221, for example, may be a black matrix formed by a metal thin film or black films.
As shown in
The display effect of the curve s may be formed by the shielding effect of the light-blocking region 221 in the transparent cover plate 22. Specifically, the light-blocking region 221 may block the upper left half of the second pixel 212 that curve s passes through as shown in
It should be noted that although it is illustrated in
Referring to
Specifically, the first pixel 211 and the second pixel 212 may be rectangular pixels of a same size. The three sub-pixels in the first pixel 211 are arranged next to each other. The two boundary lines dividing the areas occupied by the three sub-pixels in the first pixel 211 are parallel to each other. They are parallel or perpendicular to a first side of the substrate of the first pixel 211. The three sub-pixels in the second pixel 212 are arranged next to each other. The two boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 are parallel to each other. They are neither parallel nor perpendicular to a first side of the substrate of the second pixel 212. The different arrangements of the three sub-pixels of the second pixel 212 and the first pixel 211 is such that when the transparent cover plate 22 is disposed above the pixel array 21 and a light-blocking region 221 blocks a part of the second pixel 212, the portions of the three sub-pixels corresponding to the portion of the second pixels 212 that are not blocked by the light-blocking region 221 tends to be equal. Thus, color distortion at the edges of the curved portion of the display screen 20 is reduced. For details, refer to the schematic diagrams of
As shown in
Comparing
According to certain embodiments of the present disclosure, a boundary between the light-blocking region 221 and the remaining region 222 of the transparent cover plate 22 may include a plurality of curved portions. Pixels corresponding to the curved portions of the boundary line in the pixel array 21 are second pixels 212.
The boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 have a direction corresponding to the corresponding curved portion of the boundary line.
The boundary between the light-blocking region 221 and the remaining region 222 of the transparent cover plate 22 may include a plurality of curved portions. For example, in
According to certain embodiments, the boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 correspond to the curved portion of the boundary line corresponding to the second pixel 212. For example, the boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 may have a direction corresponding to the curved portion of the boundary line corresponding to the second pixel 212. For example, the boundary lines may be perpendicular or approximately perpendicular to a tangent direction of the curve portion corresponding to the second pixel 212. Alternatively, for example, the boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 may have positions corresponding to the curved portion of the boundary line corresponding to the second pixel 212, so that the portions of the three sub-pixels corresponding to the portion of the second pixels 212 that are not blocked by the light-blocking region 221 tend to be equal to each other.
By configuring the direction or positions of the boundary lines dividing the respective regions occupied by the three sub-pixels in the second pixel 212 according to the shape and direction of the curved portion of the boundary between the light-blocking region 221 and the remaining region 222 of the transparent cover plate 22, the areas of the three sub-pixels that are not displayed may be more balanced, reducing color distortion at the edge of the display area.
As shown in
As described above, the display screen 20 may include a plurality of first pixels 211 and at least one second pixel 212. Each first pixel 211 includes at least three sub-pixels, and the plurality of first pixels 211 constitute a display area of the display screen 20. The three sub-pixels of the second pixel 212 are arranged in a different manner from the three sub-pixels arranged in the first pixel 211. For example, the three subpixels of the first pixel 211 may be in arranged as shown in
According to certain embodiments, referencing
According to certain embodiments, the boundary lines dividing the areas occupied by the three sub-pixels in the second pixel 212 are parallel to each other. They also form a second angle with a first side of the substrate of the second pixel 212. The second angle is not 90° or 180°. The boundary lines dividing the areas occupied by the three sub-pixels in the first pixel 211 are parallel to each other. They also form a first angle with a first side of the substrate of the first pixel 211. The second angle is 90° or 180°.
According to certain embodiments of the present disclosure, the display screen 20 may further include a transparent cover plate 22. The inner surface of the transparent cover plate 22 has a light-blocking region 221. A boundary between the light-blocking region 221 and the remaining region 222 of the transparent cover plate 22 may include at least one curved portion. The transparent cover plate 22 may be located above the pixel array 21. The curved portion of the boundary pixels of the pixel array 21 correspond to second pixels 212. The light-blocking region 221, for example, may be a black matrix formed by a metal thin film or black films.
In addition, referring to
According to certain embodiments of the present disclosure, the pixel array 21 in the display screen 20 of the electronic device 100 includes a first pixel 211 and a second pixel 212. The three sub-pixels of the second pixel 212 are arranged in a different manner from the three sub-pixels arranged in the first pixel 211. The plurality of first pixels 211 constitute a display area of the display screen 20. And at least one second pixel 212 located in the display edge region. Thus, if the edge of the display area includes a curved portion, the arrangement manner of the three sub-pixels in the second pixel 212 may be determined correspondingly according to the shape of the curved portion. Therefore, when the edge of the curved portion of the display area is formed by partially blocking the second pixel 212, the areas of the three un-blocked sub-pixels in the second pixel 212 tend to be equal in size, which may somewhat avoid color distortion or jagged edges at the edges of the curved portion in existing technology. Therefore, the display of the electronic device is neater and pleasing, thus improving user experience.
