Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display panel, a mobile terminal and a control method thereof. Background Art

[0002] In recent years, many mobile devices, such as mobile phones, have dual display areas, referred to as a primary screen and a secondary screen. These two areas can be displayed simultaneously or separately. Foldable phones are particularly noteworthy, as they can be folded to display only the primary screen or only the secondary screen.

[0003] However, the panel corresponding to the secondary screen usually also needs to be equipped with components such as cameras and clock hands. These cameras and clock hands are usually placed in the center area of ​​the panel, which means that the area left for the secondary screen to display is relatively narrow. Therefore, a ring-shaped screen with an opening in the center, or a ring-shaped display screen, was created. This allows the aforementioned camera components to be placed in the opening area (also considered a non-display area), which helps to increase the display area of ​​the secondary screen.

[0004] However, since the non-display area in the center of the annular screen needs to be cut off, the scanning signal lines and data lines are all laid out in the cut-out area in the center of the annular screen, that is, the inner edge area. The larger the cut-out area, the more lines there are, and the larger the inner edge frame occupied by the lines. Summary of the Invention

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention will be comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, materials, devices, etc. may be adopted. In other cases, well-known technical solutions are not shown or described in detail to avoid blurring various aspects of the present disclosure. The same reference numerals in the figures represent the same or similar structures, and their detailed descriptions will be omitted.

[0028] The terms "a," "an," "the," "said," and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including," "having," and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0029] Figure 1 FIG. 1 is a schematic diagram of a display panel in the prior art. Figure 1 As shown, in the prior art, the center area of ​​the display panel used as an annular screen needs to be cut away, forming an opening 110 in the center of the display panel. The data lines 120 and scan signal lines 130 then need to be routed within the inner edge area formed between the opening 110 and the effective display area 140 of the annular screen. This results in a larger inner edge frame 150 of the annular screen, which is detrimental to the aesthetics of the annular screen and hinders increasing the area of ​​the effective display area 140 of the annular screen. Furthermore, the larger the cutaway area, the more wiring there is, and the larger the inner edge frame 150 occupied by the wiring.

[0030] like Figure 2 As shown, the present invention discloses a display panel. An opening 210 is provided in the central area of ​​the display panel, so that the display panel forms a ring screen. The display panel includes an array substrate. The array substrate includes a plurality of data lines 220 and a plurality of scanning signal lines 230. The plurality of scanning signal lines 230 and the plurality of data lines 220 intersect to define a plurality of sub-pixel units. In this embodiment, the sub-pixel unit includes at least a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first color sub-pixel, the second color sub-pixel, and the third color sub-pixel can correspond to a red sub-pixel, a blue sub-pixel, and a green sub-pixel, respectively.

[0031] The effective display area (i.e., Active Area, AA area) of the annular screen forms a first annular area 240. A first layout area 250 is formed between the inner side of the first annular area 240 and the opening 210. The outer side of the first annular area 240 extends outward to form a second layout area 260. The scanning signal lines 230 and the data lines 220 are respectively arranged in the first layout area 250 and the second layout area 260. Specifically, a local area outside the first annular area 240 forms the second layout area 260. In this embodiment, the scanning signal lines 230 are arranged in the first layout area 250, and the data lines 220 are arranged in the second layout area 260. In this way, the data lines 220 are arranged in the outer edge frame (i.e., the second layout area 260) of the annular screen, eliminating the need to arrange multiple data lines 220 and multiple scanning signal lines 230 in the inner edge frame of the annular screen, which would cause the inner edge frame to be too large, thereby effectively reducing the inner edge frame.

[0032] In this embodiment, the data lines 220 are arranged symmetrically about the annular screen. The resolution of the annular screen is A*B, and the number of pixel columns in the annular screen's effective display area is a. Since the sub-pixel units include sub-pixels of three colors, the data lines 220 are arranged symmetrically about the annular screen. Therefore, the number of data lines 220 arranged around the periphery of the annular screen is [(Aa)*3 / (2n)]. n represents the number of data lines 220 driven by each drive signal line in the multiplexed drive circuit. The number of pixel rows in the annular screen's effective display area is b. Therefore, the number of scan signal lines 230 arranged around the inner periphery of the annular screen's opening 210 is (Bb). In this case, the scan signal lines 230 are also arranged symmetrically about the annular screen. Specifically, the scan signal lines 230 include gate lines and emission lines. Since they are symmetrical about the annular screen, the number of scan signal lines 230 is [(Bb)*2 / 2], or (Bb).

[0033] Among them, A represents the number of pixels in each column of the annular screen in the vertical direction, and B represents the number of pixels in each row of the annular screen in the horizontal direction.

[0034] Figure 3 A display panel is disclosed in another embodiment of the present application. Figure 3 As shown, in this embodiment, the data line 220 can be directly input by the same external driver chip, so that the second layout area 260, that is, the outer edge frame, does not need to layout the data line, which is conducive to reducing the outer edge frame.

[0035] In another embodiment of the present application, another display panel is disclosed. In this embodiment, based on any of the above embodiments, the display panel further includes a pixel driving circuit and a multiplex driving circuit. The pixel driving circuit is used to drive the sub-pixel unit. The data line 220 is connected to the pixel driving circuit via the multiplex driving circuit. The scanning signal line 230 can be directly connected to the pixel driving circuit. The pixel driving circuit drives the plurality of data lines 220 in a time-sharing manner via each driving signal line in the multiplex driving circuit. In this way, it is possible to use the same driving signal line to drive the plurality of data lines 220 based on timing control, so that the number of data lines 220 located at the outer edge is reduced exponentially, and the inner edge frame can be significantly reduced while a small portion of the outer edge frame is increased.

[0036] In another embodiment of the present application, another display panel is disclosed. In this embodiment, based on any of the above embodiments, the outer periphery of the annular screen is circular, and the opening 210 is also circular, giving the annular screen a circular ring shape. It should be noted that the annular screen can be a rectangular annular screen, a circular annular screen, or any other shape, including irregular shapes. That is, the first annular region 240 can be of various shapes. This is not limited in this application.

[0037] In another embodiment of the present application, another display panel is disclosed. In this embodiment, based on any of the above embodiments, each drive signal line in the multiplexed drive circuit drives six data lines 220 in a time-sharing manner. In this embodiment, the number of data lines 220 arranged around the periphery of the annular screen is [(Aa) / 4].

[0038] Another embodiment of the present invention discloses a mobile terminal. The mobile terminal includes a mechanical clock hand and the display panel disclosed in any of the above embodiments. The mechanical clock hand is arranged in the opening of the annular screen, the first side of the mobile terminal is provided with a display main screen, the second side of the mobile terminal opposite to the first side is provided with the mechanical clock hand and the annular screen, and the annular screen displays the clock scale. At this time, the annular screen can be used as a display sub-screen. The mobile terminal can be a foldable device, such as a foldable mobile phone. The mobile terminal can be folded inward, and after folding, the display sub-screen using the annular screen can be used to display some basic necessary information, such as time information. This is conducive to improving the user experience.

[0039] Alternatively, the mobile terminal can be a non-foldable device, with the annular screen serving as a secondary display screen. For example, when the primary display screen is flipped downward, the mobile terminal can automatically activate Do Not Disturb mode. The secondary display screen can then be used to view basic information such as the time, improving the user experience.

[0040] Another embodiment of the present invention further discloses a method for controlling a mobile terminal, which is used to control the mobile terminal disclosed in the above embodiment. The method includes the following steps:

[0041] The motion sensor of the mobile terminal detects whether the mobile terminal is lifted and kept in the state of the first side facing downward and the second side facing upward; if so, the annular screen displays the clock scale; if not, the annular screen is turned off.

[0042] That is, when the mobile terminal is not held up, the mechanical clock hands can be used to roughly check the time, allowing users to know the approximate time, which not only improves the user experience but also achieves energy conservation. When the above conditions are met, the ring screen displays the clock scale, that is, the clock scale illuminates, allowing users to know the exact time, which helps improve the user experience.

[0043] Another embodiment of the present invention also discloses a mobile terminal. The mobile terminal includes a camera assembly, a virtual clock hand, and the display panel disclosed in any of the above embodiments. The camera assembly is disposed within the opening of the annular screen. A main display screen is disposed on a first side of the mobile terminal, and the annular screen is disposed on a second side of the mobile terminal, opposite the first side. The annular screen displays the virtual clock hand and clock scale. In this case, the annular screen serves as a secondary display screen.

[0044] Another embodiment of the present invention further discloses a method for controlling a mobile terminal, which is used to control the mobile terminal disclosed in the above embodiment. The method includes the following steps:

[0045] Determine whether the camera assembly located on the second side of the mobile terminal recognizes a human face; if so, the annular screen displays a virtual clock pointer and clock scale; if not, the annular screen turns off.

[0046] Specifically, for example, the camera component captures an image at a preset interval and determines whether the image contains a human face. It should be noted that this process does not require detailed calculations on the captured image; it only needs to determine whether a face has been recognized, which is computationally efficient. If a face is recognized, indicating that the user needs to check the time, a virtual clock hand and clock scale are displayed, which helps improve the user experience.

[0047] In summary, the display panel, mobile terminal, and control method thereof disclosed in the present invention have at least the following advantages:

[0048] The display panel, mobile terminal, and control method thereof disclosed in this embodiment effectively reduce the inner edge frame by routing the data lines from a second routing area located outside the effective display area of ​​the annular screen, thereby improving the aesthetics and user experience of the annular screen; and increasing the area of ​​the effective display area of ​​the annular screen; at the same time, a multiplexing driving circuit is used to multiplex the data lines, so that the number of data lines located at the outer edge is reduced exponentially, thereby significantly reducing the inner edge frame while increasing a small portion of the outer edge frame.
