Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before explaining the control method of the display screen provided by the present disclosure in detail, first, the display screen to which the present disclosure relates will be explained. Reference is now made to fig. 2A and 2B, wherein fig. 2A is a front view of a display screen according to an exemplary embodiment. FIG. 2B is a side view of a display screen shown in accordance with an exemplary embodiment. Although the schematic diagrams of fig. 2B and 1B are the same, the front views of fig. 2B and 1B are different from each other.
As shown in fig. 2A and 2B, the camera module 12 is disposed below the display screen 11, and a reserved partial area is not required in the display screen 11, so that the screen occupation ratio of the display screen can be improved. Specifically, the camera module 12 may be disposed at any position of the lower area of the display screen 11, for example, may be disposed at a top, middle or bottom position of the lower area of the display screen 11, and is not particularly limited in this disclosure. For convenience of explanation, the camera module 12 is disposed at the top of the area below the display screen 11 (as shown in fig. 2B) in this disclosure. The display screen 11 is a transparent display screen, and the display screen 11 may be a transparent OLED (Organic Light-Emitting Diode) display screen, for example. The camera module 12 may be a camera.
Next, a control method of the display screen provided by the present disclosure will be described in detail based on the display screens shown in fig. 2A and 2B. Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of a display screen according to an exemplary embodiment. As shown in fig. 3, the control method may include the following steps.
In step 31, it is detected whether a camera module shooting instruction is received, where the camera module shooting instruction is used to control the camera module to start shooting an image.
In this disclosure, the mode of detecting whether receive the module of making a video recording and shoot the instruction can include: whether the user touches an application icon corresponding to the camera shooting module and/or whether an instruction for opening the camera shooting module is received by the user through voice input is detected. For example, if it is detected that the user touches an application icon corresponding to the camera module, and/or an instruction for opening the camera module is received from the user through voice input, it may be considered that a camera module shooting instruction is received, and step 32 is further performed.
In step 32, in the case of receiving the shooting instruction of the camera module, if the current state of the first display screen area above the camera module is a transparent state, the camera module is controlled to start shooting images in response to the shooting instruction of the camera module.
In general, the display screen is always in an auto-refresh state after being powered on, and the current state of the display screen changes between a transparent state and a display state during the refresh process. The display screen area in the transparent state in the display screen can not display information, and the display screen area in the display state can display information. The information may be text information or icon information of an application program, and is not limited in particular.
It should be noted that, in this disclosure, first display screen region is the display screen region of module top of making a video recording, in order to guarantee that the module of making a video recording can not receive the influence of display screen display message when shooting the image, the size in this first display screen region should be greater than or equal to the size of the module of making a video recording.
Illustratively, referring to fig. 4A and 4B, fig. 4A is a front view of a display screen according to another exemplary embodiment. FIG. 4B is a side view of a display screen shown in accordance with another exemplary embodiment. As shown in fig. 4A and 4B, assuming that the camera module 12 is disposed at the top below the display screen 11, the size of the first display screen area 14 (shown by a dotted line frame in fig. 4A and 4B) is larger than the size of the camera module 12.
As shown in fig. 4A, the first display area 14 is an area on the display screen 11, and the area corresponds to the position of the camera module 12. When the first display screen area 14 is in the transparent state, no information can be displayed within the first display screen area 14. It is assumed that the current state of the other areas of the display screen 11 except the first display screen area 14 is in the display state, i.e. the white representation in the display screen is in the display state and the diagonal representation is in the transparent state as shown in fig. 4A. Icons of the application programs are displayed on the display screen 11 in areas other than the first display screen area 14. The camera module 12 can thus capture images through the first screen area 14 without being affected by information displayed on the display screen 11 in areas other than the first screen area 14. Therefore, in step 32, in the case of receiving the camera module shooting instruction, if the current state of the first display screen area above the camera module is a transparent state, the camera module is controlled to start shooting the image in response to the camera module shooting instruction.
By adopting the technical scheme, whether a shooting instruction of the camera module is received or not is detected, and the shooting instruction of the camera module is used for controlling the camera module to start shooting images; under the condition that the shooting instruction of the camera shooting module is received, if the current state of the first display screen area above the camera shooting module is a transparent state, the camera shooting module is controlled to start shooting images in response to the shooting instruction of the camera shooting module. Like this, be in the in-process of refreshing at the display screen, when the current state of the first display screen of module top of making a video recording is the transparent state, can shoot the order control this module of making a video recording and begin to shoot the image according to the module of making a video recording received, realize the purpose that the module of making a video recording shoots the image. Moreover, because the refresh rate of the display screen is high (30 frames or 60 frames can be refreshed in 1 s), according to the visual persistence effect, when the camera module shoots an image, the display screen visually observed by a person is still in a full-screen display state, so that full-screen display in the true sense is achieved.
Fig. 5 is a flowchart illustrating a control method of a display screen according to another exemplary embodiment. As shown in fig. 5, after step 32, the control method may further include the following steps.
In step 33, if the current state of the first display screen area changes to the non-transparent state, the camera module is controlled to stop shooting the image until the current state of the first display screen area changes to the transparent state.
The current state of the first display screen area changes from the transparent state to the non-transparent state as the display screen is refreshed, considering that the current state of the display screen changes between the transparent state and the display state during the refreshing. The non-transparent state indicates that the current state of the first display screen area is not a completely transparent state, and the current state of at least a partial area is a display state. In this case, if the image capturing module still continues to capture the image, the information displayed in the display of the first display screen may affect the quality of the image captured by the image capturing module, and specifically, the information displayed in the area of the first display screen may be included in the image captured by the image capturing module. Therefore, in order to avoid the interference of the information displayed in the display screen on the image shot by the camera module, in the present disclosure, if the current state of the first display screen area is changed into the non-transparent state, the camera module is controlled to stop shooting the image until the current state of the first display screen area is changed into the transparent state.
In step 34, if the current state of the first display screen area is changed to the non-transparent state, controlling the second display screen area in the first display screen area, the current state of which is in the display state, to display information.
As described above, when the first display screen area is in the non-transparent state, the current state in which at least a partial area exists in the first display screen area is the display state. That is, the first display screen region being in the non-transparent state may include: the first display screen area is either fully in a display state or a portion of the first display screen area is in a display state.
Specifically, in a case where the current state of a first display screen region is changed to a non-transparent state, first, a second display screen region in the first display screen region, the current state of which is in a display state, is determined, and then, the second display screen region is controlled to display information. The second display screen area in the display state can be used for displaying thumbnails of the application icons, the thumbnails can be thumbnails of the application icons displayed in other areas except the first display screen area in the display screen, and can also be used for splicing display information with other areas except the first display screen area in the display screen.
For example, it is assumed that the second display screen area is smaller than the first display screen area, that is, the first display screen area is not all in the display state, and the second display screen area 141 is used to display a thumbnail of the application icon. As shown in fig. 6, thumbnails of application icons displayed in other areas of the display screen 11 than the first display screen area 14 are displayed in the second display screen area.
By adopting the technical scheme, when the current state of the first display screen area above the camera module is changed into a non-transparent state, the camera module is controlled to stop shooting images, and the camera module does not shoot images at the moment, so that the interference of information displayed on the display screen on shooting images by the camera module can be avoided, and the camera module can shoot high-quality images. In addition, after the camera module is controlled to stop shooting the image, the display information of the second display screen area in the display state in the current state in the first display screen area can be further controlled, so that the screen occupation ratio of the display screen is improved.
In addition, in the prior art, since an area is reserved for the camera module in the display screen, information is not displayed in the area all the time (as shown in fig. 1A), and the time length of the area above the camera module in a transparent state in the single-frame time length refreshed by the display screen does not need to be considered in the prior art. And because in the duration of a single frame, the longer the duration in the display state is, the less the electric quantity consumed, the lower the power consumption, whereas, the longer the duration in the transparent state is, the higher the electric quantity consumed, the higher the power consumption. Therefore, in the time length of a single frame of the refresh of the display screen in the prior art, the time length in the display state is longer, and accordingly, the time length in the transparent state is shorter.
However, in the present disclosure, since the camera module is disposed below the display screen, in order to ensure that the camera module can capture high-quality images, the length of time that the first display screen region is in the transparent state needs to be extended.
Specifically, as shown in fig. 7, the control method of the display screen provided by the present disclosure may further include step 35 in addition to step 31 and step 32.
In step 35, the display screen is controlled to refresh according to a preset rule under the condition that a shooting instruction of the camera module is received.
As shown above, in the prior art, the duration of the display screen in the display state is long and the duration of the display screen in the transparent state is short, so that the camera module cannot shoot high-quality images.
In the disclosure, the consumed electric quantity, the power consumption and the quality of the image shot by the camera module are considered comprehensively, and the preset rule can be set that the proportion of the duration of the transparent state of the first display screen region in the duration of a single frame is in the range of [ 20%, 50% ]. Preferably, the ratio may be 50% to ensure that the camera module can capture a high quality image.
In addition, the refresh mode of the display screen may be one of point-by-point refresh, line-by-line refresh and full screen refresh. For example, please refer to FIGS. 8A-8B, 9A-9B, and 10A-10B, wherein FIGS. 8A and 8B are schematic diagrams illustrating a point-by-point refresh according to an exemplary embodiment. Fig. 9A and 9B are schematic diagrams illustrating a row-by-row refresh according to an example embodiment. FIGS. 10A and 10B are schematic diagrams illustrating a full screen refresh according to an exemplary embodiment. In fig. 8A-8B, 9A-9B, and 10A-10B, each cell represents a pixel, and the point-by-point refresh is performed by using a single pixel as a unit, the line-by-line refresh is performed by using each line of pixels as a unit, and the full-screen refresh is performed by using all pixels in the entire display screen as a unit. In the figure, the oblique lines indicate the transparent state, and the blank lines indicate the display state.
By adopting the technical scheme, the refreshing of the display screen is controlled by comprehensively considering the consumed electric quantity, the consumed power consumption and the quality of the image shot by the camera module, and the power consumption can be reduced as much as possible on the basis of ensuring that the camera module shoots the high-quality image.
