Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

The embodiment of the application provides a display device control method, which can be applied to a display device or electronic equipment. The electronic device may be a smartphone, a tablet, a gaming device, an Augmented Reality (AR) device, a data storage device, an audio playback device, a video playback device, a notebook, a desktop computing device, a wearable device such as a watch, glasses, a helmet, an electronic bracelet, an electronic necklace, an electronic garment, or the like, having a display screen.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. The display device 20 includes a first display region 240 and a second display region 220 adjacent to each other, and the light transmittance of the first display region 240 is greater than that of the second display region 220. It should be noted that, increasing the light transmittance of the first display area 240 can be achieved by decreasing the pixel distribution density of the first display area 240, and the lower the pixel distribution density, the lower the distribution density of the light-tight driving units connected to the pixels is, and the higher the light transmittance is. In addition, the first display area 240 may be further processed to improve light transmittance, and is not limited herein. For example, the metal wires in the first display area are changed into transparent ITO wires, and some film layers are changed into highly transparent materials.

The first display area 240 with high transmittance allows the optical element to acquire enough light signals to transmit through the first display area 240 to achieve the corresponding function. For example, an optical element such as a proximity sensor may transmit a detection signal through the first display area 240 and receive a reflection signal through the first display area 240, thereby obtaining an accurate proximity state. For another example, an optical element such as a camera may be used to acquire an image of the light signal transmitted through the first display area 240.

Among them, the first display region 240 is provided in many ways to increase its transmittance, which decreases its maximum display brightness. For example, the first display region 240 has a low pixel distribution density and a low maximum display luminance per unit area. Therefore, the maximum display luminance of the first display region 240 is less than the maximum display luminance of the second display region 220.

The second display area 220 may include a secondary display area 222 and a primary display area 224, the secondary display area 222 being contiguous with the first display area 240. The auxiliary display region 222 and the first display region 240 may be located at an end portion of the display device, and the auxiliary display region 222 and the first display region 240 may be disposed at a top or bottom or side edge portion of the entire display device 20. The secondary display area 222 and the first display area 240 may serve as display carriers for status bars, virtual key bars, and the like.

The first display area 240 and the second display area 220 of the display device 20 may be two adjacent display areas of the same display screen. The display device 20 may be used to display information such as images and characters, and the display device 20 may be used to display video, game images, photographs, tables, and the like. Before the display device 20 displays any of these pieces of information, the pieces of information are acquired in advance as information to be displayed, which includes the first display luminance and the like. It is also understood that the first display brightness calculated may be extracted before the information to be displayed is displayed. Illustratively, the information to be displayed includes a driving signal (e.g., a driving voltage) for driving each pixel, and a corresponding first display luminance may be obtained by the driving signal of each pixel, that is, the display luminance of each pixel of the display device after being displayed according to its corresponding driving signal, and the corresponding relationship between the driving signal and the display luminance may be extracted and stored in the display device or the electronic device.

The first display brightness may be the overall brightness of the information to be displayed, or may be the local brightness of the portion of the second display area adjacent to the first display area.

The display device 20 further comprises a processor 260, the processor 260 being configured to: acquiring first display brightness of information to be displayed; judging whether the first display brightness is greater than the maximum display brightness of the first display area 240; and if the first display brightness is greater than the maximum display brightness of the first display area 240, displaying the information to be displayed through the main display area 224, and displaying preset information through the auxiliary display area 222 and the first display area 240, where the display brightness of the preset information is less than or equal to the maximum display brightness of the first display area 240.

Because the maximum display brightness of the first display area 240 is smaller than the maximum display brightness of the second display area 220, if the first display brightness of the information to be displayed is larger than the maximum display brightness of the first display area 240 when the first display area 240 and the second display area 220 display images together, the display brightness of the first display area 240 is lower than that of the second display area 220, and the second display area 220 and the adjacent first display area 240 have a significant brightness difference, which causes an abrupt display of the display device 20. At this time, the main display area 224 displays information to be displayed, the auxiliary display area 222 and the first display area 240 display preset information, the second display area 220 and the auxiliary display area 222 are located at the end of the display device 20, the display brightness of the preset information is less than or equal to the maximum display brightness of the first display area 240, the first display area 240 and the main display area 224 display different contents, and the different contents correspond to the different display brightness, so that the problem of display salience caused by the brightness difference of the main display area 222 of the first display area 240 and the second display area 220 can be solved.

Exemplarily, as shown in fig. 2, the information to be displayed is a photo, the first display brightness of the information to be displayed is greater than the maximum display brightness of the first display area, if the first display area and the second display area both display the photo, the brightness of the first display area is significantly lower than that of the second display area, and the brightness difference between the first display area and the second display area is significant or causes a problem of display salience. In this embodiment, the main display area displays a photo, the auxiliary display area and the second display area display a status bar, and the display brightness of the status bar may be lower than the first display brightness or lower than the maximum display brightness of the first display area. The status bar and the photo are different display contents, and the problem of displaying the photos in a sharp manner cannot be caused even if the display brightness of the photos is different from that of the status bar.

For another example, as shown in fig. 3, the information to be displayed is an operation interface of an application program, the first display brightness of the information to be displayed is greater than the maximum display brightness of the first display area 240, if the first display area 240 and the second display area 220 both display the operation interface, the brightness of the first display area 240 is significantly lower than that of the second display area 220, and the brightness difference between the first display area 240 and the second display area 220 is significant or causes a problem of display salience. In the present embodiment, the main display area 224 displays an operation interface, the auxiliary display area 222 and the first display area 240 display a virtual key bar (including a plurality of virtual keys 282), and the display brightness of the virtual key bar may be lower than the first display brightness or lower than the maximum display brightness of the first display area 240. The virtual key bar and the operation interface have different display contents, the problem of displaying a sudden image cannot be caused due to different display brightness of the virtual key bar and the operation interface, and meanwhile, the keys of the virtual key bar can facilitate the user to return to the upper level, return to the main menu and the like.

In yet another example, the second display area may surround the first display area, and it is also understood that the first display area may be located in the middle of the second display area. The auxiliary display area and the first display area display preset information, and the main display area displays information to be displayed. The preset information may be information displayed in a split screen manner, and may also be understood as displaying the display device in a split screen manner, where the main display area serves as a first split screen interface, the auxiliary display area and the first display area serve as a second split screen interface, the first split screen interface displays information to be displayed (such as a display interface of foreground application), and the second split screen interface may display the preset information (such as a display interface of background application or a desktop display interface).

After determining whether the first display brightness is greater than the maximum display brightness of the first display region, the processor 260 may be further configured to: if the first display brightness is less than or equal to the maximum display brightness of the first display area 240, the information to be displayed is displayed through the first display area 240 and the second display area 220 together.

If the first display brightness is less than or equal to the maximum display brightness of the first display area 240, the first display area 240 and the second display area 220 can jointly display the information to be displayed, so as to maximize the display area of the display device 20. Illustratively, the information to be displayed is a game image, the first display area 240 and the second display area 220 share the game image, the game image is displayed maximally without sacrificing the first display area 240 and the auxiliary display area 222, the game image is not cut so that the user can see more game images, or the game image is not zoomed so that the user can see more game images with more proportion and more coordination, the display effect of the display device is improved, and the user experience is improved.

After the information to be displayed is jointly displayed through the first display area 240 and the second display area 220 if the first display brightness is less than or equal to the maximum display brightness of the first display area 240, the processor 260 may be further configured to: when the brightness adjustment instruction is detected and the display brightness of the second display area 220 is greater than the maximum display brightness of the first display area 240 according to the adjustment instruction, the current target display information is obtained.

The display brightness of the first display area and the second display area is below the maximum brightness of the first display area, and information can be displayed through the first display area 240 and the second display area 220 together. When the brightness adjustment instruction is detected and the display brightness of the second display area 220 is greater than the maximum display brightness of the first display area 240 according to the brightness adjustment instruction, if the image is displayed by the first display area 240 and the second display area 220 together before, the display brightness of the first display area 240 cannot match the second display area 220, that is, the display brightness of the first display area 240 is significantly lower than that of the second display area 220, which causes a problem of display salience. At this time, the display mode of the display device can be adjusted to solve the problem of displaying a sudden image. Specifically, the target display information is acquired, the target display information is displayed through the main display area 224, the preset information is displayed through the auxiliary display area 222 and the first display area 240, and the display brightness of the preset information is smaller than the maximum display brightness of the first display area 240.

It should be noted that the target display information is information displayed in the first display area 240 and the second display area 220 together. For example, the first display area 240 and the second display area 220 together display a game image, which is target display information, and then the brightness adjustment instruction is detected, and the display brightness of the second display area 220 is made greater than the maximum display brightness of the first display area 240.

The brightness adjustment instruction may be obtained through recognition of a touch layer of the display device 20, or through key trigger recognition of the electronic device, or through multiple manners such as voice recognition and gesture recognition, which is not limited herein.

After the target display information is obtained, the target display information may be displayed through the main display area 224, and the preset information may be displayed through the auxiliary display area 222 and the first display area 240. Illustratively, the target display information is a game image, the main display area 224 displays the game image, the auxiliary display area 222 and the first display area 240 display status bars, and the status bars and the game image have different display contents, so that a display obtrusiveness problem cannot be generated even if the display brightness of the status bars and the game image is different. Wherein, a frame of black picture can be inserted in the switching process to prevent the picture from flickering. That is, the black screen is displayed in the first display area 240 and the second display area 220, then the target display information is displayed in the main display area 224 of the second display area 220, and the preset information is displayed in the auxiliary display area 220 and the first display area 240 of the second display area 220.

In some embodiments, before displaying the target display information via the main display area, the processor may be further configured to: judging whether the first display area and the second display area display target display information in a full screen mode or not; if the target display information is not displayed in a full screen mode in the first display area and the second display area, zooming the target display information and then displaying the zoomed target display information in the main display area; if the first display area and the second display area display the target display information in a full screen mode, acquiring the importance of the edge content displayed by the auxiliary display area and the first display area; if the importance degree is smaller than a preset threshold value, the second display area gives up the target display information of the edge content; and if the importance degree is greater than the preset threshold value, zooming the target display information and then displaying the zoomed target display information in the main display area, or horizontally displaying the target display information in the main display area.

It is determined whether all pixels of the first display area and the second display area are used to display the target display information. Illustratively, in order to display according to the original scale of the target display information, two sides of the display device have black edges, and the middle of the display device displays the target display information, wherein the first display area and the second display area do not display the target display information in a full screen mode. In another example, if all the pixels of the first display area and the second display area of the display device are used for displaying the target display information, the target display information is displayed in a full screen, wherein the original scale of the target display information can be changed appropriately.

It can be understood that, in order to preserve the original scale of the target display information, the target display information may be displayed in the main display area after being zoomed in/out.

The importance of the edge content displayed in the auxiliary display area and the first display area can be obtained firstly, and if the importance is not important (the importance is smaller than a preset threshold), the second display area displays target display information for abandoning the edge content; the main display area still displays the same image as before, and the auxiliary display area and the second display area no longer display the previous image but display preset information (such as a status bar or a virtual key bar). The method has the advantages that part of unimportant information is abandoned, the display conversion process is not abrupt, most of areas (main display areas) of the display device are unchanged in display, adjustment (except brightness) is not needed, only the end part of the display device is needed to be changed for display, and display difference is small. If the edge content is important (the importance degree is greater than a preset threshold), the edge content is kept to be displayed continuously. Specifically, as shown in fig. 4, the target display information may be displayed in the main display area after being scaled, and the target display information may be displayed in the main display area completely and with the original scale (aspect ratio) being preserved. The target display information may also be displayed in a panning manner to the main display area. For example, as shown in fig. 5, the edge content (content 1 in the figure) is on the top of the display device, the target display information is shifted downward, the bottom content (content N in the figure) of the original target display information is temporarily not displayed, and the bottom content is displayed when the downward sliding operation is detected.

In obtaining the first display brightness of the information to be displayed, the processor is further configured to: the information to be displayed comprises a plurality of continuous display pictures, and a plurality of first display brightnesses corresponding to the display pictures are obtained, wherein one display picture corresponds to one first display brightness; judging whether the first display brightness is larger than the maximum display brightness of the first display area; if the number of the plurality of first display brightnesses which is larger than the maximum display brightness of the first display area is larger than the preset number, the information to be displayed is displayed through the main display area, the preset information is displayed through the auxiliary display area and the first display area, and the display brightness of the preset information is smaller than the maximum display brightness of the first display area.

The display device may be used for a plurality of pictures in succession, such as videos, game images, and the like. Before the display device displays the continuous multiple pictures, the continuous multiple pictures are acquired in advance as information to be displayed, and the information to be displayed comprises first display brightness and the like. It is also understood that the first display brightness calculated may be extracted before the information to be displayed is displayed. Illustratively, the information to be displayed includes a driving signal (e.g., a driving voltage) for driving each pixel, and a corresponding first display luminance may be obtained by the driving signal of each pixel, that is, the display luminance of each pixel of the display device after being displayed according to its corresponding driving signal, and the corresponding relationship between the driving signal and the display luminance may be extracted and stored in the display device or the electronic device. And after the first display brightness of the information to be displayed is obtained, comparing the first display brightness with the maximum display brightness of the first display area, and judging whether the first display brightness is greater than the maximum display brightness of the first display area. Since the number of the plurality of first display luminances greater than the maximum display luminance of the first display area is greater than the predetermined number, the predetermined number may be one third, one half, and so on of the total number of the plurality of first display luminances. At this time, it is stated that the brightness of most of the continuous multiple pictures is greater than the maximum brightness of the first display area, and is not suitable for the first display area and the second display area to display pictures together, the information to be displayed is displayed through the main display area, the preset information is displayed through the auxiliary display area and the first display area, and the display brightness of the preset information is less than the maximum display brightness of the first display area. For a specific display manner, reference may be made to the above embodiments, which are not described herein again.

Illustratively, the information to be displayed is video information, the number of the video information corresponding to the first brightness of the multi-frame pictures in front, which is greater than the maximum display brightness of the first display area, exceeds one third, the video information is displayed through the main display area, and the auxiliary display area and the second display area display the status bar.

In another example, the preset information may be information displayed in a split screen manner, or may be understood as displaying the display device in a split screen manner, where the main display area serves as a first split screen interface, the auxiliary display area and the first display area serve as a second split screen interface, the first split screen interface displays information to be displayed (e.g., a display interface of a foreground application), and the second split screen interface may display the preset information (e.g., a display interface of a background application or a desktop display interface).

After determining whether the first display brightness is greater than the maximum display brightness of the first display region, the processor may be further configured to: and if the number of the plurality of first display brightnesses which is greater than the maximum display brightness of the first display area is less than the preset number, displaying the information to be displayed through the first display area and the second display area together, wherein the first display brightness of the display picture which is greater than the maximum display brightness of the first display area is reduced and is smaller than the maximum display brightness of the first display area.

Since the number of the plurality of first display luminances greater than the maximum display luminance of the first display area is less than the preset number, the preset number may be one third, one half, and so on of the total number of the plurality of first display luminances. At this time, the brightness of most of the continuous multiple frames is less than the maximum brightness of the first display area, so that the first display area and the second display area can display the frames together, but the frame with the display brightness greater than the maximum brightness of the first display area needs to reduce the first display brightness to be less than the maximum display brightness of the first display area. It is also understood that all the display luminances in the plurality of display screens are reduced below the maximum display luminance in the first display region. Specifically, only the first display luminance of the display screen exceeding the maximum display luminance of the first display region may be reduced. The display luminance of all the display screens may be reduced, but the reduction ratio of the display luminance is different between the different display screens, and the reduction ratio is higher when the display luminance is higher, and the reduction ratio is lower when the display luminance is lower. The display luminance of only a part of the display screen with high display luminance may be reduced, and the display luminance of a part of the display screen with low display luminance may be kept unchanged.

It should be noted that, in this embodiment, the display mode may also be adjusted according to the brightness adjustment instruction. For example, when a brightness adjustment instruction is detected and the display brightness of the second display area is made to be larger than the maximum display brightness of the first display area according to the adjustment instruction, current target display information is acquired; and displaying target display information through the main display area, and displaying preset information through the auxiliary display area and the first display area, wherein the display brightness of the preset information is less than the maximum display brightness of the first display area. For details, reference may be made to the above embodiments, which are not described herein again.

The auxiliary display area and the second display area are positioned at the end part of the display device, and the processor is also used for controlling the preset information displayed in the auxiliary display area and the first display area to form a status bar or a virtual key bar in the auxiliary display area and the first display area displaying the preset information.

In order to improve the light transmittance of the first display area, the size of the pixels of the first display area is larger than that of the pixels of the second display area, the size of the pixels of the first display area is larger than that of the pixels, and the pitch between the pixels and the size of the pixels are positively correlated, that is, the larger the size of the pixels is, the larger the spacing distance between the pixels is, so that the distribution density of the pixels of the first display area is smaller than that of the pixels of the second display area, and the light transmittance of the pixel definition layer between the pixels is larger than that of the pixels, so that the larger the size of the pixels is, the higher the light transmittance of the first display area is.

In order to improve the light transmittance of the first display region, the distribution density of the pixels may be set to be smaller than that of the pixels of the second display region. The size of the pixels of the first display area is the same as that of the pixels of the second display area, the spacing distance between the pixels of the first display area is increased, the distribution density of the pixels of the first display area is smaller than that of the pixels of the second display area, and the light transmittance of the pixel definition layer between the pixels is larger than that of the pixels. Illustratively, the pixels of the second display area can reach more than 400ppi, and the brightness range is 0-550 nit; the size of the pixels of the first display area can be four times that of the pixels, the pixels of the first display area can be 200ppi, and the brightness range is 0-350 nit. It should be noted that the luminance range of the first display area has different values according to the size, distribution density, etc. of the pixels, for example, the luminance range may be 0 to 300nit, etc.

In order to improve the light transmittance of the first display region, the first driving unit disposed in the first display region may be a simplified driving circuit. Specifically, the second display region includes a plurality of second driving units, and one second driving unit drives one pixel. The first driving unit of the first display region may be a simpler driving circuit than the second driving unit of the second display region. The first driving unit includes a smaller number of thin film transistors than the second driving unit. Because the thin film transistors are opaque, the number of the opaque thin film transistors in the first driving unit is small, the occupied area is small, the opaque area of the driving circuit layer is small, the ratio of the transparent area of the driving circuit layer is high, and the light transmittance of the driving circuit layer and the first display area can be improved. For example, the second driving unit is a 7T1C driving circuit, and the first driving unit may be a 5T1C or 2T1C driving circuit.
