Fig. 2 is a block diagram illustrating a configuration of a display apparatus according to an exemplary embodiment of the present invention. As shown in fig. 2, the display apparatus 200 includes at least one of a tuner demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

In some embodiments, the controller 250 includes a processor, a video processor, an audio processor, a graphic processor, a RAM, a ROM, a first interface to an nth interface for input/output.

The display 260 is used for displaying an interface, and includes a display screen component for displaying pictures, and a driving component for driving image display, and is used for receiving image signals from the controller output, displaying video content, image content and a menu manipulation interface, and manipulating a UI interface by a user.

The display 260 may be a liquid crystal display, an OLED display, and a projection display, and may also be a projection device and a projection screen, and in the embodiment of the disclosure, the OLED display is mainly taken as an example.

The communicator 220 is a component for communicatively connecting with an external device or a server according to various communication protocol types. For example: the communicator may include at least one of a Wifi module, a bluetooth module, a wired ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The display apparatus 200 can be communicatively connected with the remote control apparatus 100 or the server 400 through the communicator 220, i.e., establish transmission and reception of control signals and data signals.

The user interface is a medium interface for interaction and information exchange between an application program or an operating system and a user, and realizes conversion between an internal form of information and a form acceptable by the user. A commonly used presentation form of the User Interface is a Graphical User Interface (GUI), which refers to a User Interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In order to better guide the user to use the tv, the existing solution usually designs a home interface (or preview mode), a specific UI Display mode, allowing the network video and physical channel signals to be viewed through a small window, and introduces information such as a hot play tv or a history record in other parts (in some application scenarios, it may also be called an OSD (On Screen Display) area). In the process of playing video in the small window, the picture changes dynamically, namely the color and the brightness of each pixel change randomly, and the corresponding screen light emitting is relatively uniform in loss; the OSD part of the picture is fixed, and the brightness difference is generated in the long run, so that the 'ghost' phenomenon appears, especially when the picture is switched to a full-screen pure color picture card, the phenomenon is particularly obvious.

In order to solve the above problems, the following solutions are generally adopted:

1. among the reasons for generating the afterimage in the OLED display, the brightness is the most important one — the afterimage phenomenon is more serious when the brightness is larger in the same time and the same picture. The OLED display can achieve ultrahigh definition, the OSD part can be designed into a dark style, and the viewing of a user is basically not influenced when the overall brightness of the OLED display is reduced. The display content in a part of the area is in the form of pictures such as posters, which cannot be solved in this way. Fig. 3 is a schematic diagram of a first display screen according to the present invention.

2. Most OLED displays, without signal input (including no video being played on the homepage), start the screen saver mechanism after a certain time, usually dynamically play some scenery pictures and reduce the screen brightness. By the mode, the random change of the television picture is kept, the relatively uniform loss of screen luminescence is ensured, and the probability of generating ghost shadow is reduced. If there is a small window, the size of the playing window can be detected, and if the window is not full of the screen or is smaller than a certain proportion of the window size, the screen saver is started after waiting for a certain time (such as five minutes). This may affect some users watching videos with small windows, and the experience is not good. Fig. 4 is a schematic diagram of a second display screen according to the present invention.

3. The partial OLED display has a local static frame detection function, namely, the whole picture is subdivided into a plurality of sub-areas (such as 64X 64), the change condition of each subarea picture is detected in real time, and once the local picture is static and unchanged for a certain time, the screen brightness is reduced to prevent the local area from generating 'ghost shadow'. When the small window plays a scene, as the surrounding pictures are static, the local static frame function is triggered and the screen brightness is reduced. Since the function is designed for the scene with bright blocks in local areas when the video is played, the amplitude of reducing the screen brightness is very small. If the small window is used for playing for a long time, the phenomenon of 'ghost shadow' still can occur.

The above three schemes realize the afterimage prevention function on the screen brightness from different angles and different degrees, but cannot achieve good effect. When a user stays in a small window playing scene, the phenomenon of 'ghost shadow' caused by long-term use (the default scene of television startup is possible, and the user does not watch the television) is serious.

Fig. 3 is a schematic diagram of a display screen according to an exemplary embodiment of the present invention. Taking a television as an example, when the television displays a screen, the television may be divided into a plurality of panels (or regions), as shown in fig. 3, a region corresponding to a "small window" in the screen is generally a region corresponding to a dynamic screen, that is, a display region of the screen corresponding to a display signal, and regions "1", "2", "3", "4", "5", "6", "7", "8", "9" and "10" in fig. 3 are generally displayed as static screens, which may be posters, menus, advertisements, and the like. When watching television, especially watching television contents for a long time, a user generally only pays attention to the contents of the display area corresponding to the "small window" in fig. 3, but does not pay attention to the contents of other areas. For the OLED television, a still picture is displayed for a long time, and the brightness is too high, which may aggravate the problem of the afterimage of the OLED television.

To solve the foregoing technical problem, some embodiments of the present invention provide a picture adjustment apparatus. Fig. 5 is a schematic structural diagram of a picture adjustment apparatus according to an exemplary embodiment of the present invention. As shown in fig. 5, the picture adjustment apparatus includes a signal receiving module 510 configured to acquire a display signal; a mode judging module 520 configured to determine whether the display mode is a window mode based on the display signal; a parameter adjusting module 530 configured to adjust display parameters of the window region and the non-window region respectively to reduce the afterimage; a parameter holding module 540 configured to hold the display parameter at a default value; the display parameter at least comprises one of brightness, gray-scale value, contrast, saturation and color intensity, and before being adjusted, the display parameter is kept as a default value; the mode determination module 520 is electrically connected to the signal receiving module 510, the parameter adjustment module 530 is electrically connected to the mode determination module 520, and the parameter holding module 540 is electrically connected to the mode determination module. In the above embodiment, the display signal represents a signal corresponding to a content requested by a user, and is applied to the above fig. 3, that is, a signal corresponding to a content displayed in the "small window" area; the display mode may include a window mode and a full screen mode, when the display mode is in the window mode, the picture corresponding to the display signal is windowed, and the size of the picture corresponding to the display signal is smaller than the total display area of the display, which is also exemplified as fig. 3, when the display mode is in the full screen mode, the picture corresponding to the display signal is full screen, and the size of the picture corresponding to the display signal is equal to the total display area of the display, that is, the picture corresponding to the display signal is fully paved on the display; the window region represents a display region of a screen corresponding to the display signal, that is, a region corresponding to the "small window" in fig. 3, and the non-window region represents a display region other than the screen corresponding to the display signal, that is, regions corresponding to "1", "2", "3", "4", "5", "6", "7", "8", "9", and "10" in fig. 3; in some application scenarios, the non-window area in the present embodiment may also be referred to as an OSD (On Screen Display) area, i.e., an area displaying set contents. It should be noted that although the example is given in fig. 3 above, it is not meant that when the display mode is the window mode, the window region can only be located at a position corresponding to the "small window" region in fig. 3, and those skilled in the art will understand that the position of the window region can be changed or moved freely; the default value represents an initial value of the display parameter when the user does not actively adjust the display parameter or does not adjust the display parameter by the picture adjustment device in this embodiment, and in some application scenarios, the default value may also be referred to as a default value.

After receiving the display signal, the signal receiving module 510 may send the display signal to the mode determining module 520, where the mode determining module 520 calculates whether the picture corresponding to the display signal is in a full-screen mode according to information such as resolution of the display picture included in the display signal, and the scheme for determining whether the picture is in a window mode may be any one known by those skilled in the art, and is not limited herein. After the mode determining module 520 determines that the display mode is the window mode according to the display signal, a first confirmation signal may be sent to the parameter adjusting module 530, and the parameter adjusting module 530 generates an adjusting instruction immediately after receiving the first confirmation signal, and adjusts the brightness of the window region and the brightness of the non-window region based on the adjusting instruction, more specifically, for example, the default value of the brightness is 100%, the brightness of the window region may be reduced to 80%, the brightness of the non-window region is reduced to 20%, and so on; if the display mode is the full screen mode, a second confirmation signal may be sent to the parameter holding module 540, and after receiving the second confirmation signal, the parameter holding module 540 generates a holding instruction and holds the display parameters unchanged based on the holding instruction.

Based on the above scheme, the embodiment of the disclosure starts from the principle of the OLED display, and on the premise of not affecting the use experience of the user, the display parameters of the window area and the non-window area are respectively adjusted when the display mode is the window mode, so that the ghost of the OLED display is reduced.

Fig. 6 is a flowchart illustrating a screen adjustment method according to an exemplary embodiment of the present invention. In some embodiments, the screen adjusting apparatus performs the following steps shown in fig. 6:

s501, acquiring a display signal;

s502, judging whether the display mode is a window mode or a full-screen mode based on the display signal, if the display mode is the window mode, executing S503, and if the display mode is the full-screen mode, executing S504;

s503, adjusting display parameters of the window area and the non-window area respectively to reduce ghost shadows;

the display parameter at least comprises one of brightness, gray-scale value, contrast, saturation and color intensity, and before being adjusted, the display parameter is kept as a default value;

s504, the display parameter is kept as the default value.

In some embodiments, the image adjusting device may obtain the display signal, determine, according to the display signal, that the display mode is a window mode or a full-screen mode, adjust the display parameters for the window area and the non-window area when the display mode is the window mode, and keep the display parameters at default values when the display mode is the full-screen mode. Based on the adjusting method, based on the principle of the OLED display, for example, the brightness values of the non-window area and the window area are reduced to different degrees, and the afterimage of the OLED display is reduced on the premise of not influencing the user experience.

Fig. 7 is a schematic flowchart illustrating a first picture adjustment method according to an exemplary embodiment of the present invention. In some embodiments, after the mode determining module 520 is configured to determine the display mode to be the window mode or the full screen mode based on the display signal, the following steps shown in fig. 7 are further performed:

s601, judging whether the display duration corresponding to the display signal is greater than or equal to a first duration threshold or not based on the display signal, if so, executing S503, and if not, executing S504.

In some embodiments, even if the display mode corresponding to the display signal is the window mode, the display parameter may not need to be adjusted because the display duration of the picture corresponding to the display signal is short; for example, the display mode of the display signal is the window mode, but the display time length of the screen corresponding to the display signal is only 10s (time unit: second), and therefore, the display parameter does not need to be adjusted. After the mode determining module 530 determines that the display mode is the window mode or the full-screen mode based on the display signal, the above steps may be performed, that is, after the mode determining module 530 determines that the display mode is the window mode, the mode determining module 530 may determine, based on the display signal, whether the display duration corresponding to the display signal is greater than or equal to a first duration threshold, for example, the first duration threshold is 1min (time unit: minute), and the display duration corresponding to the display signal is 10min, obviously, if the display duration is greater than the first duration threshold, a first confirmation signal may be sent to the parameter adjusting module 530, so that the parameter adjusting module 530 performs the above step S503; similarly, if the display duration is less than the first duration threshold, a second confirmation signal may be sent to the parameter holding module 540, so that the parameter holding module executes the step S504.

Based on the scheme, whether the display parameters are adjusted or not can be determined more accurately according to the actual scene, and the situation that the display parameters are adjusted too frequently is prevented.

Fig. 8 is a schematic flowchart illustrating a second picture adjustment method according to an exemplary embodiment of the present invention. In some embodiments, the mode determining module 520 is configured to, after determining whether the display duration corresponding to the display signal is greater than or equal to the first duration threshold based on the display signal and before performing S503, further include:

s701, generating a full screen prompt instruction and starting timing for the first time;

the full screen prompting instruction is used for prompting a user to switch the display mode to a full screen mode, and the timing duration of the first time is a first duration;

s702, judging whether a picture switching instruction sent by a user is received or not within a first time length, if the picture switching instruction for switching the full screen is received, executing S703, if the picture switching instruction for maintaining a window is received, executing S704, and if no picture switching instruction is received within the first time length, executing S705;

s703, switching the display mode to a full screen mode, and executing S504;

s704, keeping the display mode as a window mode, and executing S503;

s705, after the first duration, the display mode is switched to the full-screen mode, and S504 is executed.

In some embodiments, in order to reduce the problem of image sticking in principle from the OLED display, a user may be guided to change the window mode to the full-screen mode, so as to improve the viewing experience, and the OLED display reduces the duration of displaying a static image and reduces image sticking. Therefore, the mode determining module 520 is configured to determine whether the display duration corresponding to the display signal is greater than or equal to the first duration threshold based on the display signal, and after determining that the display duration is greater than or equal to the first duration threshold, the mode determining module 520 may further perform generating a full screen prompting instruction to prompt the user to switch to the full screen mode, and generating a timing instruction to start first timing, where the timing duration corresponding to the first timing is the first duration; if the picture switching instruction of the user is received within the first time period, adjusting the display mode according to the picture switching instruction of the user; for example, if a screen switching instruction for holding the window is received, the display mode is held as the window mode, and the parameter adjusting module 530 executes the above S503; for another example, if a screen switching instruction for switching to the full screen is received, the display mode is switched to the full screen mode, and the parameter holding module 540 executes the above S504; if no picture switching instruction is received within the first time period, automatically switching the display mode to the full-screen mode after the first time period, and enabling the parameter holding module 540 to execute the step S504; in the above solution, the received screen switching instruction may be in any form, for example, the user may control the screen switching instruction by voice, or by a remote control device, or by an intelligent device, and so on.

Based on the scheme, the display mode can be guided to be switched to the full-screen mode by the user, so that the time for the OLED display to display a static picture is reduced, and the ghost is reduced; from a practical perspective, since an appropriate guiding prompt such as "suggest you to switch to full screen viewing, improve viewing experience" and the like may be displayed on the display when the prompt to switch to full screen mode is issued, the probability of switching the display mode to full screen mode may be improved, and the ghost may be reduced, even if the user persists in selecting the window mode, the parameter adjusting module 530 may perform the adjustment on the display parameters of the window area and the non-window area, respectively, to reduce the ghost; based on various conditions, various schemes are provided to reduce the ghost shadow.

Fig. 9 is a specific flowchart illustrating a third picture adjustment method according to an exemplary embodiment of the present invention. In some embodiments, the parameter adjusting module 530 is configured to adjust the display parameters of the window region and the non-window region respectively, specifically including:

s801, starting second timing, reducing the brightness values of a window area and a non-window area after the timing duration of the second timing reaches a second duration, and simultaneously ending the second timing;

s802, starting timing for the third time, reducing the gray-scale value, the contrast and the saturation of the non-window area after the timing duration of the timing for the third time reaches the third duration, and ending the timing for the third time.

In some embodiments, the adjustment of the display parameter is not done at once, and in order to ensure the user experience, it is necessary to extend the time period for adjusting the display parameter, that is, after the display mode is maintained as the window mode, the parameter adjusting module 530 starts to perform the second timing, and after the timing time period of the second timing reaches the second time period, the brightness values of the window region and the non-window region are reduced, while the second timing is ended, and starts the third timing, and after the timing time period of the third timing reaches the third time period, the gray level value, the contrast and the saturation of the non-window region are reduced, while the third timing is ended.

Referring to table 1 below, table 1 gives an example of a scheme for parameter adjustment. Specifically, a plurality of different parameter adjustment schemes may be set, and the numbers shown in table 1 are all reduced ratios; taking the first scheme in table 1 as an example, the second duration may be 100s, that is, after the window mode is maintained at 100s, the brightness values of the window region and the non-window region are reduced to 40% of the default value, for example, the brightness default values of the window region and the non-window region are 300nit (brightness unit: nit), and the brightness values of the window region and the non-window region may be reduced to 120nit; after reducing the brightness value to 120nit and maintaining it at 100s, reducing the gray-scale value of the non-window area to 30% of the gray-scale default value, reducing the contrast of the non-window area to 50% of the contrast default value, and reducing the saturation of the non-window area to 20% of the saturation default value; taking the default value of the gray scale value as 50 (the gray scale value is between 0 and 100), the gray scale value of the non-window region can be reduced to 15, taking the default value of the contrast as 50 (the contrast is between 0 and 100), the contrast of the non-window region can be reduced to 25, taking the saturation as 50 (the saturation is between 0 and 100), the saturation of the non-window region can be reduced to 10. For the user, the picture content of the non-window area is not concerned by the user or is not the key point for the user to watch, so that the display parameters of the non-window area can be reduced to a lower level, the ghost shadow is greatly reduced, and the use experience of the user cannot be influenced; however, the window area is the focus of the user, so that the adjustment of the display parameters should be limited, and the display parameters are reduced without affecting the user experience, so as to reduce the afterimage, and fig. 10 is a schematic diagram of the adjusted display screen according to the exemplary embodiment of the present invention.

In some embodiments, multiple parameter adjustment schemes may be preset, and the first duration, the brightness dimming ratio, the second duration, the gray-scale value dimming ratio, the contrast dimming ratio, and the saturation dimming ratio in each scheme are preset and have a certain difference, so as to improve the usability and adaptability of the parameter adjustment scheme; the user may pre-select different parameter adjustment schemes, and after selecting an adjustment scheme, the parameter adjustment module 530 may perform adjustment on the display parameters of the window area and the non-window area based on the selected parameter adjustment scheme, so as to reduce the ghost.

In some embodiments, multiple parameter adjustment schemes may be preset, the first duration, the brightness dimming ratio, the second duration, the gray-scale value dimming ratio, the contrast dimming ratio, and the saturation dimming ratio in each scheme may be set by a user, and the user may implement a function of editing the parameter adjustment scheme through a specific operation, so that the picture adjustment method is more suitable for each user.

Based on the scheme, the display parameters of the window area and the non-window area can be adjusted in sequence based on the timing duration, and the ghost shadow is reduced on the premise of not influencing the use experience of a user; in addition, different parameter adjusting schemes can be selected in advance, so that the parameter adjusting schemes are more suitable for the use habits of users; in addition, the user can edit the parameter adjusting scheme by himself, so that the parameter adjusting scheme completely meets personal requirements of the user, and use experience of the user is improved.

TABLE 1 parameter adjustment scheme Table

Fig. 11 is a detailed flowchart illustrating a fourth picture adjustment method according to an exemplary embodiment of the present invention. In some embodiments, the parameter adjusting module 530 is configured to adjust the display parameters of the window region and the non-window region respectively, specifically including:

and S1001, reducing the color intensity of at least one primary color of red, green and blue in the window area, and restoring the color intensity to a default value again after reducing the color intensity of any one primary color.

Continuing with table one above, in some embodiments, after or simultaneously with the display parameter adjustment of the non-window area, the display parameter adjustment may also be performed on the window area. A color trimming switch can be set, the color trimming switch is connected to the parameter adjusting module 540, the parameter adjusting module 540 can sequentially generate color adjusting instructions for reducing the color intensities of the three primary colors of red, green and blue according to the set adjusting sequence and send the color adjusting instructions to the color trimming switch, the color trimming switch adjusts the color intensities after receiving the color adjusting instructions, and the color intensity default values of the three primary colors are 50 (the color intensities are between 0 and 100). The specific adjustment scheme may be: firstly reducing the red intensity to 40% of a default value, then restoring the red intensity to the default value, secondly reducing the green intensity to 40% of the default value, then restoring the green intensity to the default value, thirdly reducing the blue intensity to 40% of the default value, and thirdly restoring the green intensity to the default value; the above process is repeatedly circulated.

In some embodiments, in order to reduce the use experience of the user when adjusting the color intensity, taking the process of reducing the red intensity as an example, the red intensity may be adjusted in a more gradual process, for example, the red intensity is reduced from 50 to 20, 30s may be used as an adjustment period, that is, the red intensity is reduced by 1 per second, after the red intensity is reduced to 20, 30s is used as an adjustment period, that is, the red intensity is increased by 1 per second, and the red intensity is restored to 50, so as to reduce the influence on the viewing experience of the user.

In some embodiments, the color intensities of the three primary colors red, green and blue may also be adjusted simultaneously.

In some embodiments, the color intensities of the three primary colors red, green and blue may also be adjusted simultaneously but discriminatively in sequence. For example, the adjustment periods of the three primary colors of red, green and blue are all 30s, the red intensity may be adjusted first, the green intensity may be adjusted 5s after the red intensity is adjusted, and the blue intensity may be adjusted 5s after the green intensity is adjusted.

Based on the scheme, the color intensity of the window area can be adjusted, and under the premise that the use experience of a user is not influenced, the ghost shadows of the red, green and blue pixel points are reduced.

In some embodiments, the parameter adjusting module 530 is configured to adjust the display parameters of the window region and the non-window region respectively, specifically including:

continuously judging whether an operation instruction from a user is received or not when the display parameters of the window area and the non-window area are respectively adjusted;

if so, immediately restoring the display parameters to default values;

if not, the display parameters are kept as the adjusted numerical values.

In some embodiments, when the display parameters of the window area and the non-window area are adjusted, or after the display parameters of the window area and the non-window area are adjusted, if a user inputs any operation instruction, for example, an operation instruction is issued through a remote control device, or an operation instruction is issued through voice, or an operation instruction is issued through an intelligent device, and the user wants to perform an operation, the display parameters are immediately restored to the default values, so that the user can see all contents of the window area and the non-window area, and the operation is facilitated.
