Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments 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 smart phone, tablet, gaming device, augmented reality (Augmented Reality, AR) device, data storage, audio playback, video playback, notebook, desktop computing device, wearable device such as a watch, glasses, helmet, electronic bracelet, electronic necklace, electronic clothing, etc. with a display screen.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the application. The display device 20 includes a first display area 240 and a second display area 220 adjacent to each other, and the first display area 240 has a light transmittance greater than that of the second display area 220. It should be noted that, increasing the light transmittance of the first display area 240 may be achieved by decreasing the pixel distribution density of the first display area 240, and the lower the pixel distribution density, the lower the light-impermeable driving unit distribution density connected to the pixels, and the higher the light transmittance thereof. In addition, the first display area 240 may be subjected to other processes for improving the light transmittance, which are not limited herein. For example, the metal traces in the first display area are changed to transparent ITO traces, some of the film layers are changed to high light transmission materials, etc.

The first display area 240 with high light transmittance can enable the optical element to acquire the optical signal that sufficiently transmits 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 optical signal transmitted through the first display area 240.

Among them, the first display area 240 is provided with many settings in order to increase its light transmittance, and reduces its maximum display brightness while increasing the light transmittance. For example, the pixel distribution density of the first display area 240 is low, and the maximum display luminance per unit area is also low. Therefore, the maximum display brightness of the first display area 240 is smaller than the maximum display brightness of the second display area 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 area 222 and the first display area 240 may be located at the end of the display device, and the auxiliary display area 222 and the first display area 240 may be disposed at the top or bottom or side of the entire display device 20. The auxiliary 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 text, and the display device 20 may be used to display video, game images, photographs, desktops, and the like. Before the display device 20 displays any one of these pieces of information, these 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 of the information to be displayed may be extracted and calculated before it is displayed. The information to be displayed includes a driving signal (e.g., a driving voltage) for driving each pixel, and the driving signal of each pixel may obtain a corresponding first display luminance, that is, the display luminance of each pixel of the display device after displaying according to the corresponding driving signal, where the correspondence between the driving signal and the display luminance may be extracted and obtained and stored in the display device or the electronic apparatus.

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, wherein 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 area 240 and the second display area 220 together display an image, the first display brightness of the information to be displayed is larger than the maximum display brightness of the first display area 240, the display brightness of the first display area 240 will be lower than the second display area 220, and the second display area 220 and the adjacent first display area 240 will have a significant brightness difference, so that the display of the display device 20 will be abrupt. At this time, the main display area 224 is used to display the information to be displayed, the auxiliary display area 222 and the first display area 240 are used to display the 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 different display brightness, so that the problem of abrupt display caused by the brightness difference between the main display area 222 of the first display area 240 and the second display area 220 can be solved.

As shown in fig. 2, the information to be displayed is a photo, and the first display brightness of the information to be displayed is greater than the maximum display brightness of the first display area. In this embodiment, the photo is displayed through the main display area, the auxiliary display area and the second display area display the status bar, and the display brightness of the status bar may be lower than the first display brightness or may be lower than the maximum display brightness of the first display area. The status bar and the photo are different display contents, and the display brightness of the photo and the status bar is different, so that the problem of abrupt display is avoided.

As 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, and if both the first display area 240 and the second display area 220 display the operation interface, the brightness of the first display area 240 is significantly lower than the second display area 220, and the first display area 240 and the second display area 220 have a significant brightness difference or cause a display abrupt problem. In this embodiment, the main display area 224 is used to display the operation interface, and the auxiliary display area 222 and the first display area 240 are used to display a virtual key bar (including a plurality of virtual keys 282), where the display brightness of the virtual key bar may be lower than the first display brightness or may be lower than the maximum display brightness of the first display area 240. The virtual key bar and the operation interface are different display contents, the display brightness of the virtual key bar and the operation interface is different, the problem of abrupt display cannot be generated, and meanwhile, the keys of the virtual key bar can be convenient for a user to return to the previous stage, return to a main menu and the like.

In yet another example, the second display area may surround the first display area, and it is understood that the first display area may be intermediate 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 by a split screen, or may be understood that the display device is split-screen displayed, the main display area is used as a first split screen interface, the auxiliary display area and the first display area are used as a second split screen interface, the first split screen interface displays information to be displayed (such as a display interface of a foreground application), and the second split screen interface may display preset information (such as a display interface of a background application or a desktop display interface).

After determining whether the first display luminance is greater than the maximum display luminance 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 together 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 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 are used for displaying the game image together, the first display area 240 and the auxiliary display area 222 are not required to be sacrificed, the game image can be displayed maximally, the game image is not cut, so that a user can see more game images, or the game image is not scaled, so that the user can more proportion and coordinate the game images, the display effect of the display device is improved, and the user experience is improved.

After the information to be displayed is displayed by 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 processor 260 may be further configured to: when the brightness adjustment command is detected, and the display brightness of the second display area 220 is made to be greater than the maximum display brightness of the first display area 240 according to the adjustment command, the current target display information is acquired.

The display brightness of the original second display area and the first display area are below the maximum brightness of the first display area, and information can be displayed together through the first display area 240 and the second display area 220. When the brightness adjustment command 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 command, if the images are displayed together according to the previous first display area 240 and the second display area 220, the display brightness of the first display area 240 cannot be matched with the second display area 220, i.e. the display brightness of the first display area 240 is obviously lower than the second display area 220, so that the display is abrupt. At this time, the display mode of the display device can be adjusted to solve the problem of abrupt display. 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.

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 collectively display a game image, which is target display information, and then a brightness adjustment instruction is detected, and the display brightness of the second display area 220 is made larger than the maximum display brightness of the first display area 240.

The brightness adjustment command may be obtained through recognition of a touch layer of the display device 20, or may be obtained through key triggering recognition of an electronic device, or may be obtained through various 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, the status bars and the game image are different display contents, and even if the status bars and the game image are different in display brightness, the display is not abrupt. Wherein, a frame of black picture can be inserted in the switching process, so that the picture flickering problem is prevented. That is, the first display area 240 and the second display area 220 display a black screen, and then the main display area 224 of the second display area 220 displays target display information, and the sub display area 220 of the second display area 220 and the first display area 240 display preset information.

In some embodiments, the processor may be further configured to, prior to displaying the target display information via the main display area: judging whether the first display area and the second display area display target display information in a full screen mode; if the first display area and the second display area do not display the target display information in a full screen mode, displaying the target display information in the main display area after zooming; if the first display area and the second display area display the target display information in a full screen mode, acquiring importance of the auxiliary display area and edge content displayed in the first display area; if the importance is smaller than the preset threshold, 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, displaying the target display information in the main display area after zooming, or displaying the target display information in a translation manner 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. For example, in order to display the target display information according to the original proportion of the target display information, two sides of the display device are provided with black edges, the middle of the display device displays the target display information, and the first display area and the second display area are not full-screen display of the target display information. In another example, all pixels of the first display area and the second display area of the display device are used to display the target display information, and then the target display information is displayed in full screen, where the original proportion of the target display information can be changed appropriately.

It can be appreciated that, if the first display area and the second display area do not display the target display information in full screen, in order to preserve the original proportion of the target display information, the target display information may be scaled and displayed in the main display area.

The importance degree of the edge content displayed in the auxiliary display area and the first display area can be firstly obtained, and if the importance degree is not important (the importance degree is smaller than a preset threshold value), the second display area displays target display information for discarding 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 display conversion process is not abrupt, most of the area (main display area) of the display device is unchanged, adjustment (except brightness) is not needed, only the end part of the display device is needed to be changed for display, and the display difference is small. If the edge content is important (importance degree is larger than a preset threshold value), 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 with its integrity and the original scale (aspect ratio) maintained. The target display information may also be displayed in translation to the main display area. For example, as shown in fig. 5, the edge content (content 1 in the figure) is at the top of the display device, the target display information is shifted downward, and the bottom content (content N in the figure) of the original target display information is temporarily not displayed, and is displayed again when the downward sliding operation is detected.

In acquiring 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 brightness corresponding to the plurality of display pictures is 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; and if the number of the maximum display brightness larger than the first display area in the plurality of first display brightness is larger than the preset number, displaying the information to be displayed 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 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 video, game images, etc. Before the display device displays the continuous multiple pictures, the continuous multiple pictures are acquired in advance to serve 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 of the information to be displayed may be extracted and calculated before it is displayed. The information to be displayed includes a driving signal (e.g., a driving voltage) for driving each pixel, and the driving signal of each pixel may obtain a corresponding first display luminance, that is, the display luminance of each pixel of the display device after displaying according to the corresponding driving signal, where the correspondence between the driving signal and the display luminance may be extracted and obtained and stored in the display device or the electronic apparatus. 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 larger than the maximum display brightness of the first display area. Because the number of the plurality of first display luminances greater than the maximum display luminance of the first display area is greater than the preset number, the preset number may be one third, one half, or the like of the total number of the plurality of first display luminances. At this time, the brightness of most of the continuous multiple pictures is larger than the maximum brightness of the first display area, and is not suitable for the first display area and the second display area to jointly display the pictures, so that 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 specific display manner may refer to the above embodiments, and will not be described herein.

The information to be displayed is a video information, the number of the video information corresponding to the first brightness greater than the maximum display brightness of the first display area in the plurality of first brightness of the previous multi-frame picture exceeds one third, the video information is displayed through the main display area, and the auxiliary display area and the second display area display status bars.

In another example, the preset information may be information displayed on a split screen, or it may be understood that the display device is displayed on a split screen, the main display area is used as a first split screen interface, the auxiliary display area and the first display area are used as a second split screen interface, the first split screen interface displays information to be displayed (such as a display interface of a foreground application), and the second split screen interface may display preset information (such as a display interface of a background application or a desktop display interface).

After determining whether the first display luminance is greater than the maximum display luminance of the first display region, the processor may be further configured to: and if the number of the maximum display brightness larger than the first display area in the plurality of first display brightness is smaller 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 larger than the maximum display brightness of the first display area is reduced to be smaller than the maximum display brightness of the first display area.

Because the number of the plurality of first display luminances greater than the maximum display luminance of the first display area is smaller than the preset number, the preset number may be one third, one half, or the like of the total number of the plurality of first display luminances. In this case, the brightness of most of the continuous multiple pictures is smaller than the maximum brightness of the first display area, so that the first display area and the second display area can jointly display the pictures, but the pictures with the display brightness larger than the maximum brightness of the first display area need to reduce the first display brightness so as to be smaller than the maximum display brightness of the first display area. It is also understood that all of the display brightness in the plurality of display screens is reduced below the maximum display brightness of the first display area. Specifically, only the first display luminance of the display screen exceeding the maximum display luminance of the first display area may be reduced. The display luminance of all the display screens may be reduced, but the ratio of the reduction of the display luminance is different from one display screen to another, and the ratio of the reduction of the display luminance is lower as the ratio of the reduction of the display luminance is higher. The display luminance of the display screen with the larger display luminance may be reduced only in part, and the display luminance of the display screen with the smaller 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 greater than the maximum display brightness of the first display area according to the adjustment instruction, current target display information is obtained; 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 smaller than the maximum display brightness of the first display area. The specific embodiments may be referred to above, and will not be described herein.

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 preset information displayed in the auxiliary display area and the first display area.

In order to improve the light transmittance of the first display region, the size of the pixels of the first display region may be set to be larger than the size of the pixels of the second display region, the size of the pixels of the first display region is larger than the size of the pixels, the spacing 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, and thus the distribution density of the pixels of the first display region is smaller than the distribution density of the pixels of the second display region, and the light transmittance of the pixel defining layer between the pixels is larger than the light transmittance of the pixels, and thus the larger the size of the pixels is, the higher the light transmittance of the first display region is.

In order to increase the light transmittance of the first display region, the distribution density of pixels may also be set to be smaller than that 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 interval 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 defining layer between the pixels is larger than that of the pixels, so that the smaller the distribution density of the pixels of the first display area is, the larger the interval distance between the pixels is, and the light transmittance of the first display area is higher. Illustratively, the pixels of the second display area may be up to 400ppi or more, with a luminance in the range of 0-550 nit; the pixels of the first display area may have a size of four times that of the pixels, and the pixels of the first display area may have a brightness ranging from 0 to 350nit. The luminance range of the first display region may have different values according to the size, distribution density, and the like of the pixels, for example, the luminance range may be 0 to 300 nit.

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 area includes a plurality of second driving units, and one second driving unit drives one pixel. The first driving unit of the first display area may be a more abbreviated driving circuit than the second driving unit of the second display area. 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 thin film transistors which are opaque in the first driving unit is smaller, the occupied area is smaller, the opaque area of the driving circuit layer is smaller, the light transmittance of the driving circuit layer and the first display area can be improved due to the fact that the light transmittance of the driving circuit layer is higher. For example, the second driving unit is a 7T1C driving circuit, and the first driving unit may be a 5T1C or 2T1C driving circuit.

In order to increase the light transmittance of the first display region, the distribution density of the first driving unit may be set to be smaller than that of the second driving unit. The plurality of pixels of the first display area may be divided into a plurality of pixel sets, that is, the first display area includes a plurality of pixel sets, each pixel set includes at least two pixels connected in parallel with each other, the pixels of the first display area and the second display area have the same physical structure, and all the pixels in the pixel sets share a first driving unit.
