Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Wherein in the description of the embodiments of the present application, "/" indicates an inclusive meaning, for example, a/B may indicate a or B; "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

The display brightness of a display screen of the VR device or the AR device is related to a duty ratio and a peak current, and under the same display brightness, the higher the duty ratio is, the lower the corresponding peak current is, and the lower the duty ratio is, the higher the corresponding peak current is.

Some applications show under the high duty cycle, the smear appears easily in the display screen, and some applications show under the high duty cycle, and the smear is not easy to appear in the display screen, for example, when VR equipment moves recreation class application under the high duty cycle, the smear appears easily in the display screen, but when running album application, characters under the high duty cycle and reading application etc. the smear is difficult to appear in the display screen.

Based on this, the application provides a display method, in which the display screen displays the application which is easy to generate the smear at a low duty ratio and a high peak current, and when the application which is easy to generate the smear is switched to the application which is not easy to generate the smear, the display screen displays the application which is not easy to generate the smear at a high duty ratio and a low peak current under the same display brightness. Therefore, when the display screen displays the application of the smear which is not easy to appear with high duty ratio and low peak current, the damage of high peak current to the luminescent material can be avoided on the premise of ensuring the display effect, and the service life of the luminescent material of the display screen is prolonged.

The method and the device can be applied to VR equipment or AR equipment or mixed reality equipment. Among other things, a VR device may be a device with processing functions (e.g., decoding and rendering, view angle capturing, re-projecting, and eye lens correction, etc.) and the ability to play VR video. The VR equipment may be a VR machine.

For example, the VR device may be a head-mounted VR display device, a VR helmet (e.g., an all-in-one virtual reality helmet, a virtual reality helmet connected to a mobile phone end, a virtual reality helmet connected to a desktop computer, a light guide mixed reality helmet, an augmented reality helmet, etc.), VR glasses (VR Glass) with a processing function, a VR Box (VR Box) with a processing function, a device with a function of playing a panoramic video, such as a computer or a television, etc. Of course, the VR device can also be any other device that can be used to process and play VR video.

In addition, the VR device may also have a screen projection function.

As shown in fig. 2, specifically, referring to a schematic structural diagram of an electronic device 200 provided in an embodiment of the present application, reference may be made to the electronic device 200 for a hardware structure of a VR or AR device shown in the present application. The electronic device 200 may be used to perform the display methods provided herein.

Referring to fig. 3, a schematic diagram of a display method provided in an embodiment of the present application is shown. The principle of the display method provided by the present application is described below with reference to fig. 2 and 3.

Fig. 3 shows a Display panel 202, a Display Driver IC (DDIC) 302, and a GPU. The DDIC302 is used for receiving image digital signals corresponding to each application inputted by the GPU in the electronic device 200 and converting the image digital signals into analog signals (current-voltage) so as to output a specific current-voltage at each pixel and control the liquid crystal or light emitting layer of the display panel to emit a desired luminance value.

DDIC 202 contains registers 304, and registers 304 store a database 308.

In one embodiment, the database 308 stores preset flags, such as high, midle, and low, added by each application SDK (Software development kit). And when the preset mark identification display screen displays the application corresponding to the preset mark, the duty ratio is used.

The preset flag may be added to the SDK of the application by a developer when developing the application. The preset flag added by the SDK for each application is determined based on whether the application is prone to smear when running at high duty cycle. The smear is a fault phenomenon that horizontal stripes appear on displayed fonts, pictures, windows and the like, and the horizontal stripes can be long or short based on the severity of the fault. The occurrence of smear on the display screen is related to the frame rate, and the lower the frame rate, the more severe the smear. And decreasing the duty ratio is equivalent to decreasing the display time of one frame, which is equivalent to increasing the frame rate. For example, for a display screen with a frame rate of 90Hz, a 20% duty cycle corresponds to a frame rate of 450 Hz. Therefore, increasing the duty cycle is equivalent to decreasing the frame rate, which increases the likelihood of smearing on the display screen of the electronic device.

Some applications may further increase the likelihood of smearing when displayed at high duty cycles. For example, when the VR device displays a game application, a user may use a head-moving function of the VR device, where the user dynamically changes a picture in the VR device when moving the head of the user, and the head-moving function has a high requirement on a response time of the display screen, and the faster and more frequent the user moves the head, the faster the display screen switches, and the easier the display screen generates a smear. Thus, applications for the game class should not run at a high duty cycle, otherwise the likelihood of smearing will be further increased. However, when some photo album or video application is run by the VR device, the photo album or video application does not use the functions of head movement and the like. Therefore, compared with game applications, when the display screen displays photo albums, video applications or screen projection applications under high duty ratio, smear is not easy to generate, and the use of a user is not influenced.

In one embodiment, a preset mark low is added to an SDK of an application which is displayed at a high duty ratio and is prone to smear on a display screen, and when the display screen is identified to display an application corresponding to the preset mark low, a small duty ratio and a large peak current are used. Illustratively, a preset flag low is added to the SDK of the game application or the driving operation application. And when the display screen displays the application corresponding to the preset mark high, the large duty ratio and the small peak current are used. Illustratively, a preset mark high is added in the SDK of an album application, a text reading application, a music application, and a desktop application. And adding a preset mark midle to the SDK of other applications, and using a relatively medium duty ratio and a relatively medium peak current when the display screen displays the application corresponding to the preset mark midle. Illustratively, preset markup midlets are added to the SDKs of video playing applications, cell phone screen applications, and distance learning applications.

The database 308 stores not only the preset flag corresponding to each application SDK, but also the correspondence with the duty ratio and the peak current at the same display luminance.

Exemplarily, referring to table 1, the correspondence relationship between the preset flag, the duty ratio and the peak current of different SDKs applied at the first display brightness is specifically shown.

Application program	Marking	Duty cycle	Corresponding to peak current
				Applications
1	Low	a ₁ ＝10％	I ₁
				Applications 2	Middle	a ₂ ＝20％	I ₂
Applications 3	High	a ₃ ＝30％	I ₃

TABLE 1

In table 1, at the first display brightness, the preset mark low corresponding to the application 1, and the duty ratio corresponding to the preset mark low is a ₁ =10% peak current I ₁ The preset flag corresponding to the application 2 is middle, and the methodThe duty ratio corresponding to the preset mark midle is a ₂ =20% peak current I ₂ Applying the preset mark high corresponding to the 3, and the duty ratio corresponding to the preset mark high is a ₃ =30% peak current I ₃ Wherein a is ₁ *I ₁ ＝a ₂ *I ₂ ＝a ₃ *I ₃ 。

It is understood that above I ₁ >I ₂ >I ₃ 。

Illustratively, at a first display brightness, the display screen is at duty cycle a ₁ And peak current I ₁ Displaying the application 1, wherein when the application 1 is switched to the application 3, the display screen can be based on a preset mark High corresponding to the SDK of the application 3 and a duty ratio a corresponding to the application 1 ₁ And peak current I ₁ Addressing in the database to obtain the duty ratio a corresponding to the application 3 ₃ And peak current I ₃ Then based on the duty cycle a ₃ And peak current I ₃ The application 3 is displayed with the first display luminance.

Illustratively, referring to table 2, another correspondence of duty ratio and peak current at the first display luminance is specifically shown.

Table 2 includes the contents of table 1, and also includes the corresponding relationship between the duty ratio and the peak current at the first display luminance when the electronic device does not display an application. The fact that the electronic equipment does not display the application means that the display screen of the electronic equipment does not display the interface content of the application currently, and the display screen is located on the main page.

When the electronic device 200 does not display an application, the display screen is at duty cycle a ₄ And peak current I ₄ Display at the first display luminance, it can be understood that a ₁ *I ₁ ＝a ₂ *I ₂ ＝a ₃ *I ₃ ＝a ₄ *I ₄ . Duty ratio a ₄ And peak current I ₄ For addressing in display applications.

Illustratively, the duty cycle a is used at a first display brightness when the electronic device is not displaying an application ₄ And peak current I ₄ The display screen is driven. When the user opens the application 1, the DDIC can obtain the SDK preset mark of the application 1Note low and preset flag low, duty cycle a based on SDK of application 1 ₄ And peak current I ₄ Addressing, obtaining and duty cycle a ₁ Corresponding peak current I ₁ 。

TABLE 2

At the first display brightness, when the application 1 is switched to the application 3, the DDIC may determine the duty ratio a of the display application 3 by acquiring the preset flag of the application 3 ₃ And based on applying a duty cycle a corresponding to 1 ₁ And peak current I ₁ Determining and duty ratio a ₃ Corresponding peak current I ₃ . Then at a duty cycle a ₃ And peak current I ₃ The application 3 is displayed.

The preset flag is used to determine the duty cycle that should be used for the display application in the database. It will be appreciated that the duty cycle to be used in displaying the application may be identified by other means than by a preset flag.

In one embodiment, a white list may be set in the database 308, the applications within the white list are applications that are prone to smear when displayed at a high duty cycle, and the applications outside the white list are applications that are not prone to smear when displayed at a high duty cycle. And when the application identification display screen in the white list displays the application in the white list, the small duty ratio and the large peak current are used. And when the application identification display screen outside the white list displays the application in the white list, the large duty ratio is used. For example, the corresponding relationship between the duty ratio and the peak current when the applications in the white list and the applications outside the white list are displayed at the same display brightness may be preset, and the preset relationship may be stored in the database 308 for the DDIC to call.

Referring to table 3, the correspondence between duty ratio and peak current when displaying the application in the white list and the application outside the white list at the first display luminance is specifically shown.

Application program	Whether it is in the white list	Duty cycle	Corresponding to peak current
				Applications
1	In the white list	a ₁ ＝10％	I ₁
				Application 3	Outside of white list	a ₃ ＝30％	I ₃

TABLE 3

As shown in table 3, application 1 is an application within the white list and application 3 is an application outside the white list. Under the first display brightness, the duty ratio corresponding to the application 1 is a ₁ =10% peak current I ₁ The duty ratio corresponding to application 3 is a ₃ =30% peak current I ₃ Wherein the duty ratio a ₁ =10% peak current I ₁ The corresponding display brightness is equal to the duty ratio a ₃ =30% peak current I ₃ Corresponding display brightness, i.e. a ₁ *I ₁ ＝a ₃ *I ₃ . It can be understood that I ₁ >I ₃ 。

Illustratively, at a first display brightness, the display screen is at duty cycle a ₁ And peak current I ₁ Displaying the application 1, and when the application 1 is switched to the application 3, the DDIC judges that the application 3 is out of the white list, thereby determining the duty ratio a corresponding to the display application 3 ₃ Then based on duty cycle a ₃ Duty ratio a ₁ And peak current I ₁ Addressing in the database to obtain the duty ratio a ₃ Corresponding peak current I ₃ And based on the duty cycle a ₃ And peak current I ₃ The application 3 is displayed at a first display brightness.

Illustratively, referring to table 4, another correspondence of the duty ratio and the peak current at the first display luminance is specifically shown.

Table 4 includes the contents of table 3, and also includes the corresponding relationship between the duty ratio and the peak current at the first display luminance when the electronic device does not display an application.

When the electronic device 200 is not running an application, the display screen is at duty cycle a ₄ And peak current I ₄ Displaying at a first display brightness, it can be understood that ₁ *I ₁ ＝a ₃ *I ₃ ＝a ₄ *I ₄ . Duty ratio a ₄ And peak current I ₄ For addressing in display applications.

Illustratively, the duty cycle a is used at a first display brightness when the electronic device is not running an application ₄ And peak current I ₄ The display screen is driven. When a user opens the application 1, the DDIC judges and acquires the application 1 in a white list, and therefore the duty ratio a of the application 1 is determined to be displayed ₁ . Based on duty ratio a ₁ Duty ratio a ₄ And peak current I ₄ Addressing, obtaining and duty cycle a ₁ Corresponding peak current I ₁ Then based on duty cycle a ₁ And peak current I ₁ The application 1 is displayed at a first display brightness.

Application program	Whether it is in the white list	Duty cycle	Corresponding to peak current
				Applications
1	In the white list	a ₁ ＝10％	I ₁
				Application 3	Outside of white list	a ₃ ＝30％	I ₃
NONE		a ₄ ＝x％	I ₄

TABLE 4

At a first display brightness, when application 1 switches to application 3, the DDIC may determine the duty cycle a of the display application 3 by determining that application 3 is outside the white list ₃ And based on the duty ratio a corresponding to the first application ₁ And peak current I ₁ Determining and duty ratio a ₃ Corresponding peak current I ₃ 。

Referring to fig. 4A and 4B, fig. 4A shows a graph illustrating a relationship between a duty ratio and a peak current corresponding to application of 1 at the first display luminance value, and fig. 4B shows a graph illustrating a relationship between a duty ratio and a peak current corresponding to application of 3 at the first display luminance value.

As shown in FIG. 4A, at the first display brightness value, the display screen is at duty ratio a ₁ =10% peak current I ₁₂ The nth frame image and the (N + 1) th frame image of the application 1 (e.g., game application) are displayed. Wherein due to the duty cycle a ₁ =10%, the writing of data is performed by applying the first 90% of the time in the nth frame image and the (N + 1) th frame image of 1 without lighting the display screen, and the last 10% of the time in the nth frame image and the (N + 1) th frame image lights the display screen, and then a ₁ Peak current of =10% corresponding to I ₁₁ 。

As shown in FIG. 4B, at the first display brightness value, the display screen is at duty ratio a ₃ =30% peak current I ₃ The nth frame image and the (N + 1) th frame image of an application (e.g., an album application) are displayed. Wherein due to the duty cycle a ₃ =30%, the data is written by using the first 70% time in the nth frame image and the (N + 1) th frame image of 3, the display screen is not lighted, and the display screen is lighted at the last 30% time of the nth frame image and the (N + 1) th frame image, and the duty ratio a is related to ₃ Peak current of =30% correspondence is I ₃ 。

It is clear that I ₁ >I ₃ ，I ₃ ＝1/3I ₁ Compared with the application 1, the display screen uses smaller peak current to display the application 3, so that the damage of high peak current to the luminescent material of the display screen is avoided, and the service life of the luminescent material is prolonged.

Further, the registers of the DDIC204 also store a scene recognition algorithm 310, a matching algorithm 312, and the like. The scene recognition algorithm 310 includes a first scene recognition algorithm and a second scene algorithm, and the matching algorithm 312 includes a first matching algorithm and a second matching algorithm. And when the DDIC runs the first scene recognition algorithm, the preset mark stored in the application program SDK currently displayed in the electronic equipment can be recognized. After the preset mark is determined, the DDIC runs a first scene matching algorithm to address the duty ratio and the peak current in the database in the DDIC according to the preset mark and the current display brightness, and the corresponding duty ratio and the peak current are found through addressing.

And when the DDIC operates the second scene identification algorithm, whether the application program currently displayed in the electronic equipment is in a white list can be identified, and according to the identification result, the DDIC operates the second scene matching algorithm to address the duty ratio and the peak current in the database in the DDIC according to the identification result and the display brightness, and the corresponding duty ratio and the corresponding peak current are found through addressing.

Also included in the DDIC is a parameter output module 306 for inputting analog signals corresponding to the duty cycle and the peak current determined by the matching algorithm into the cathode and anode of the LCD liquid crystal or OLED light emitting layer of the display panel 202. The display panel 202 displays a corresponding display brightness value based on the analog signal output by the parameter output module 306.

Referring to fig. 5A-5D, a graphical user interface of an electronic device 200 according to an embodiment of the present application is described.

Referring to fig. 5A, a main interface of the electronic device 200 is shown, and an icon 502 of application 1 and an icon 504 of application 2 are exemplarily displayed on the main interface of the electronic device 200. Illustratively, the application 1 is a photo album application and the application 2 is a shooting game.

When the electronic device 200 is turned on, the DDIC can detect the duty ratio a of the driving display screen ₄ And peak current I ₄ Illustratively, duty cycle a ₄ And peak current I ₄ The corresponding display brightness is the first display brightness. It should be noted that, in the display method disclosed in the present application, during the execution process, the display brightness of the display screen is maintained at the first display brightness.

In one embodiment, the user selects one of the open photo album application or the shooting game from the graphical interface shown in FIG. 5A to display the contents of the open application on the display screen. Alternatively, the user opens both the album application and the shooting game, one application running in the background and the other displayed in the foreground.

Illustratively, as shown in fig. 5A, when the user clicks the icon 502 of the shooting game, the electronic device 200 responds to the clicking operation of the user to acquire the preset mark a corresponding to the shooting game SDK ₁ Then, thenBased on the duty cycle a before the user opens the shooting game ₄ And peak current I ₄ And a preset mark low, addressing in the database, and determining the corresponding duty ratio a of the shooting game ₁ Corresponding peak current I ₁ Then based on the duty cycle a ₁ And peak current I ₁ The content of the shooting game application is displayed at the first display luminance. Illustratively, referring to fig. 5B, a graphical interface displayed for a shooting game of the electronic device 200 at a first display brightness.

In an embodiment, as shown in fig. 5C, the user may also directly click on the icon 504 of the album application, and the electronic device 200 responds to the click operation of the user to obtain the preset flag high corresponding to the album application SDK, and then based on the duty ratio a before opening the album application ₄ And peak current I ₄ And a preset mark high, addressing in the database, and determining the duty ratio a corresponding to the photo album application ₃ Corresponding peak current I ₃ And at a duty cycle a ₃ And peak current I ₃ The application 3 is displayed. Illustratively, referring to fig. 5D, a graphical interface of the photo album application is displayed at a first display brightness for the electronic device 200.

In one embodiment, at a first display brightness, a user opens both a photo album application and a shooting game, wherein the shooting game application runs in the foreground and displays and the photo album application runs in the background. Under the first display brightness, the display screen has a duty ratio a ₁ And peak current I ₁ And displaying the interface content of the shooting game. The user may switch the interface of the shooting game directly to the graphical interface of the photo album application. Illustratively, the user switches the shooting game to the photo album application through an auxiliary device as described above, such as a handle, i.e., the user switches the graphical interface shown in fig. 5B directly to the graphical interface shown in fig. 5D. For example, upon switching to the graphical interface shown in fig. 5D, the electronic device 200 may determine the duty ratio a with the preset flag high of the SDK of the album application ₃ . And then based on duty cycle a ₃ And duty ratio a corresponding to shooting game application ₁ And peak current I ₁ Addressing in the database to obtain the duty ratio a of the photo album application ₃ And peak current I ₃ And based on the duty cycle a ₃ And peak current I ₃ Displaying the photo album application.

Due to I ₃ Is less than I ₁ ，a ₁ Is greater than I ₃ The method ensures enough display brightness and display effect, can enable the electronic equipment to display the photo album application at low peak current, and prolongs the service life of the luminescent material of the display screen.

It is to be understood that, in the above embodiment, the duty ratio used by the application when displaying the application may be determined not only by the flag in the SDK, but also by determining whether the application belongs to the application in the white list, or by other means, and this is not limited herein.

Referring now to fig. 6, shown is a flow chart of a display method according to an embodiment of the present application. In one embodiment, the display method provided herein can be applied to the electronic device 200. In one embodiment, the display method provided by the application can also be applied to a semiconductor chip.

The following describes a display method shown in the present application, taking the electronic device 200 as an example, and includes:

in step 602, the electronic device 200 obtains a first duty ratio and a first peak current when the display screen of the electronic device displays a first application. Wherein the electronic device displays a first application at a first display brightness based on the first duty cycle and the first peak current.

The first application is an application being displayed by the electronic device, and the first display brightness is the current display brightness of the display screen. The first application may be the application 1, and the first duty ratio from the display screen to the display of the first application is a ₁ =10%, the first peak current is I ₁ 。

Step 604, when the first application is switched to a second application, obtaining a second duty cycle for operating the second application, and determining a second peak current based on the first duty cycle and the first peak current. And the display brightness of the electronic equipment display screen under the first duty ratio and the first peak current is equal to the display brightness of the electronic equipment display screen under the second duty ratio and the second peak current.

This step will be described below by taking the first application as the application 1 and the second application as the application 3 as examples. Illustratively, after application 1 switches to application 3, DDIC may read the preset flag high of the SDK of application 3. The electronic device 100 addresses from the database 308 of the DDIC302 based on the preset mark high of the SDK of the application 3, and finds the second duty ratio a corresponding to the preset mark high ₃ . Since the display brightness of the display screen at the first duty ratio and the first peak current is equal to the display brightness of the display screen at the second duty ratio and the second peak current, the display brightness may be based on the first duty ratio a ₁ =10% and a first peak current I ₁ And a second duty cycle a ₃ =30%, the second peak current I of the running application 3 is determined in the database 308 ₃ 。

This step will be described below by taking the first application as the application 1 and the second application as the application 3 as examples. In another embodiment, after the application 1 is switched to the application 3, the electronic device 100 reads the application in the white list to determine whether the application 3 is in the white list. For example, if the application 3 is out of the white list, the second duty ratio a of the display screen displaying the application 3 may be determined ₃ . Since the display brightness of the display screen at the first duty ratio and the first peak current is equal to the display brightness of the display screen at the second duty ratio and the second peak current, the electronic device may be based on the first duty ratio a ₁ And a first peak current I ₁ And a second duty cycle a ₃ Determining a second peak current I for running a second application in the database 208 ₃ 。

Illustratively, the second application may include, but is not limited to, a gaming application, the second application may include, but is not limited to, a photo album application, a video application, a screen projection application, and the like.

A second application is displayed based on the second duty cycle and the second peak current, step 606.

After the second duty cycle and the second peak current are obtained, the display screen displays the application at the second duty cycle and the second peak current. For example, when the second duty ratio is larger than the first duty ratio and the second peak current is smaller than the first peak current, that is, the electronic device runs the second application at a lower peak current, the display life can be better extended.

In another embodiment, after the display screen displays the second application with the second duty ratio and the second peak current, the user may also actively adjust the display panel to display the second peak current and the second duty ratio of the second application as needed without changing the brightness.

In one embodiment, under the same display brightness, the corresponding relationship between a plurality of duty ratios and peak currents corresponding to the duty ratios when the display screen displays the second application may be set, and the corresponding relationship is stored in the database of the DDIC for the DDIC to call.

Referring to table 5, the correspondence between the duty ratio of the second application and the peak current displayed on the display screen at the first display brightness is specifically shown in one embodiment of the present application.

Application program	Duty cycle	Corresponding to peak current
			Second application	a ₃₁ ＝30％	I ₃₁
Second application	a ₃₂ ＝35％	I ₃₂

TABLE 5

Illustratively, the display screen of the electronic device may be at duty cycle a ₃₁ =30% peak current I ₃₁ Displaying a second application, or displaying the screen with duty cycle a ₃₂ =35% peak current I ₃₂ Displaying a second application, wherein a ₃₁ *I ₃₁ ＝a ₃₂ *I ₃₂ It can be understood that I ₃₁ >I ₃₂ 。

Illustratively, at a first display brightness, the electronic device is at duty cycle a ₃₁ =30% peak current I ₃₁ The second application is displayed. An adjustment control may be provided in the display screen for adjusting the peak current at which the duty cycle of the second application is displayed. For example, when the user clicks the adjusting control, the display screen responds to the clicking operation of the user, so that the display screen is enabled to be in the duty ratio a ₃₂ =35% peak current I ₃₂ The second application is displayed. In this embodiment, the user can adjust the peak current and the duty cycle as needed to reduce the peak current for displaying the second application and extend the life of the real material.
