In order to clarify the aspects provided by the present application, the following description is made of various embodiments with reference to the accompanying drawings.

The embodiment of the application discloses an OLED display screen dimming method applied to two-dimensional code scanning, which is applied to terminal equipment, and refers to a work flow diagram shown in FIG. 3, and the method comprises the following steps:

and step 31, monitoring whether the two-dimensional code appears on the display interface of the display screen.

When a user uses the terminal device, the two-dimensional code may be opened at any time, for example, when shopping payment is made, and electronic payment is needed while riding a bus or taking a subway. Therefore, the terminal equipment monitors whether the two-dimension code appears on the display interface in real time in the operation process.

Illustratively, the terminal device may scan the display interface of the display screen in real time through a built-in two-dimensional code scanning program, and analyze a scanning result to monitor whether the two-dimensional code appears on the display interface.

Illustratively, the terminal device may further perform screenshot on the display interface, and analyze and detect the screenshot to monitor whether the two-dimensional code appears on the display interface.

When the terminal equipment monitors whether the two-dimension code appears on the display interface in real time, the terminal equipment can simultaneously operate in any application running process no matter through a two-dimension code scanning program or a screenshot mode.

And 32, after the display interface is monitored to have the two-dimensional code, increasing the lighting time of target pixel points in a unit time period, wherein the target pixel points comprise each pixel point in a target area of the display screen.

Generally, after a user opens a two-dimensional code on a terminal device, the two-dimensional code does not relate to the area of the whole display interface of an OLED display screen, and a blank area of a certain size exists between the edge of the two-dimensional code and the edge of the display interface.

The target area provided by this embodiment includes an area for displaying the two-dimensional code, that is, the target area is greater than or equal to a display area of the two-dimensional code on the display screen, and the target area completely covers the display area of the two-dimensional code on the display screen.

Aiming at all pixel points in the target area, the lighting time of the pixel points in the unit time period is increased, so that the extinguishing time of each pixel point is shortened. When sweeping code equipment and scanning the two-dimensional code that terminal equipment demonstrates, short extinguishing time can all be maintained to all pixel in at least two-dimensional code place region to ensure to sweep most pixel that code equipment read and can be in the state of lighting, so can reduce the quantity and the width of black twill, eliminate the black twill even, make to sweep code equipment and can discern the two-dimensional code fast, improve recognition efficiency and rate of accuracy.

In one implementation, the unit time period is equivalent to one dimming cycle, and dimming cycles of different models of display screens in the PWM dimming mode are different, and for example, some dimming cycles of the display screens are one millisecond, some dimming cycles of the display screens are fifty microseconds, and the shorter the dimming cycle is, the higher the performance requirement and power consumption of the display screens are.

In this implementation manner, the lighting duration of the target pixel point in the unit time period is increased, that is, the duty ratio of the target pixel point in each dimming cycle is increased. In order to ensure that code scanning equipment does not influence the identification of the two-dimensional code when scanning, in this embodiment, the duty ratio of target pixel point in unit time period is adjusted to the duty ratio maximum value that can reach under the PWM dimming mode for the luminance in target area reaches the maximum luminance that this display screen can reach, generally speaking, as long as the display screen reaches the brightest degree under the PWM dimming mode, code scanning equipment just can not scan out the black twill, so alright ensure quick and accurate identification two-dimensional code.

In another implementation mode, the target pixel point is directly converted from the default PWM dimming mode to the DC dimming mode, so that the target pixel point is kept normally on in each unit time period and cannot be extinguished. Since the DC dimming mode is a way to change the brightness of the screen by increasing or decreasing the circuit power, the code scanning device will not catch the black twill no matter how low the brightness of the display screen is in the DC dimming mode.

The DC mode of adjusting luminance also is an automatic mode of adjusting luminance, and when the target area conversion of display screen was the DC mode of adjusting luminance, although target pixel had all become normally bright, can maintain the original luminance of display screen always, so not only can improve two-dimensional code identification efficiency and rate of accuracy, can avoid the display screen target area to become bright moreover under the darker circumstances of environment to prevent to cause the injury to user's eyes.

A blank area with a certain size exists between the edge of the two-dimensional code and the edge of the display interface, so the size of the target area is set according to the following two cases.

In the first case, the entire area of the display screen is set as a target area, and in this case, the target area includes a two-dimensional code area and a blank area. When the terminal equipment monitors that the two-dimension code appears on the display interface, the lighting time of all pixel points is increased aiming at all areas of the display screen.

In the second case, a display area of the two-dimensional code on the display screen is set as a target area, in which case the blank area is not included in the target area. When the terminal equipment monitors that the two-dimension code appears on the display interface, the lighting time of all pixel points is increased aiming at the display area of the two-dimension code. In this case, the area involved in the brightness adjustment is reduced not for the entire area of the display screen but only for a partial area of the display screen, so that discomfort given to the eyes of the user can be reduced as much as possible, and the power consumption of the display screen can be reduced to the maximum extent.

For the first situation, when the lighting time of the target pixel point in the unit time period is increased, the method can be realized in the following two ways:

the first realization mode is as follows: aiming at all pixel points in all areas of the display screen, the duty ratios of the pixel points in the unit time period are adjusted to the duty ratio highest value which can be reached under the PWM dimming mode, so that the whole display screen is completely brightest, and when the code scanning equipment scans, the whole display screen cannot be shielded by black twill, so that the recognition efficiency and the accuracy of the two-dimensional code can be ensured to the maximum extent.

The second implementation manner is as follows: to all pixel in the whole region of display screen, convert them from PWM mode of adjusting luminance into DC mode of adjusting luminance for all pixel all become normally bright, so whole display screen can not have black twill.

To above-mentioned two kinds of implementation, if under the relatively dim circumstances of environment, the whole region of display screen in the second kind of implementation can maintain lower luminance always, can avoid the display screen full-screen to become bright suddenly to cause the injury to user's eyes, moreover because luminance is lower, the consumption also is less than first implementation, consequently, under the relatively dim circumstances of environment, can use second kind of implementation. However, if the environment is brighter, because the DC dimming mode increases the brightness of the display screen by increasing the circuit power, and the phenomenon of screen burning may occur in long-time high-brightness use, if the second implementation mode is used, all the pixels are completely changed into the DC dimming mode and maintain higher brightness, and the power consumption of the display screen is much higher than that of the first implementation mode, so that the first implementation mode can be adopted in the case of brighter environment.

For the second case, when increasing the bright-up duration of the target pixel point in the unit time period, the following two implementation manners may be implemented:

the first realization mode is as follows: aiming at all pixel points of the two-dimensional code in the display area on the display screen, the duty ratio of the pixel points in the unit time period is adjusted to the duty ratio highest value which can be reached under the PWM dimming mode, so that the display area of the two-dimensional code on the display screen is brightest, and the two-dimensional code is ensured not to be shielded by black twill when the code scanning equipment scans.

The second implementation manner is as follows: all pixel points of the two-dimensional code in the display area on the display screen are converted into a DC dimming mode from a PWM dimming mode, so that the display area of the two-dimensional code cannot be shielded by black twill.

Similarly, for the two implementation manners in the second case, under the condition that the environment is dark, the second implementation manner can avoid the display screen from becoming bright so as to prevent the eyes of the user from being injured, and the power consumption is lower than that of the first implementation manner. However, in the case of a bright environment, the power consumption of the display screen of the second implementation will be higher than that of the first implementation.

Aiming at the two situations, a first realization mode can be adopted when the environment is brighter, and a second realization mode is adopted when the environment is darker. In order to judge which implementation mode is adopted to adjust the brightness of the display screen, in actual operation, the terminal equipment can acquire the brightness of the environment light through the optical sensor, when the brightness of the environment light is not less than a preset threshold value, a first implementation mode is adopted, otherwise, a second implementation mode is adopted.

In the scheme provided by the embodiment of the application, no matter the target area is the whole area of the display screen, or the two-dimensional code is located in the display area on the display screen, before the time of the lighting of the target pixel point is increased, the display screen is always in the PWM dimming mode of adjusting the brightness of the display screen along with the brightness of the environment, and the time of the lighting of each pixel point is matched with the brightness of the environment.

Therefore, if the current lighting time of the target pixel point is obtained before the lighting time of the target pixel point is increased, the terminal equipment can quickly control the brightness of the display screen to adapt to the ambient brightness again when the user closes the two-dimensional code.

Therefore, the embodiment further provides an OLED display screen dimming method applied to two-dimensional code scanning, referring to the workflow diagram shown in fig. 4, the method includes:

and step 41, monitoring whether the two-dimensional code appears on the display interface of the display screen.

Step 42, after the two-dimensional code on the display interface is monitored, acquiring the initial lighting time of a target pixel point, wherein the initial lighting time is the lighting time of the target pixel point in the current unit time period, the target pixel point comprises each pixel point in a target area of the display screen, and the target area comprises an area for displaying the two-dimensional code.

The "current time period" disclosed in the present embodiment refers to a time period before the operation of "increasing the light-on duration of the target pixel point in the unit time period" is performed. In the current time period, all pixel points in the display screen are in a PWM dimming mode, and the duty ratio of each pixel point is adaptive to the current ambient light brightness.

In a first implementation manner for the two cases, although the duty ratio of the target pixel point is adjusted to the highest value, the dimming frequency is not changed, and when the subsequent two-dimensional code is closed, only the duty ratio of the target pixel point needs to be restored to the original state, so that the initial lighting time of the target pixel point may only include: and the duty ratio of the target pixel point in the current unit time period.

To the second kind of implementation in above-mentioned two kinds of circumstances, owing to changed the mode of adjusting luminance of target pixel, when follow-up two-dimensional code was closed, if want to restore target pixel to the PWM mode of adjusting luminance of current time quantum from the DC mode of adjusting luminance, need all restore target pixel's duty cycle and the frequency of adjusting luminance to the former state, therefore the initial of target pixel is lighted and is lasted long not only including: the duty ratio of the target pixel point in the current unit time period further comprises: and the dimming frequency of the target pixel point in the current unit time period.

And 43, increasing the lighting time of the target pixel point in the unit time period.

When the two-dimension code on the display interface is monitored, the terminal equipment increases the lighting time of the target pixel points, so that the extinguishing time of each pixel point is shortened. When sweeping code equipment and scanning the two-dimensional code that terminal equipment demonstrates, short extinguishing time can all be maintained to all pixel in at least two-dimensional code place region to ensure to sweep most pixel that code equipment read and can be in the state of lighting, so can reduce the quantity and the width of black twill, eliminate the black twill even, make to sweep code equipment and can discern the two-dimensional code fast, improve recognition efficiency and rate of accuracy.

And step 44, monitoring whether the two-dimension code of the display interface is closed.

After the user opens the two-dimensional code by using the terminal device, the two-dimensional code may be closed at any time, and the terminal device executes step 44, which may be executed after increasing the lighting time (i.e., step 43) of the target pixel point in the unit time period, or may be executed when the terminal device monitors that the two-dimensional code appears on the display interface.

If the terminal device monitors that the two-dimensional code appears on the display interface, step 44 is executed, in this case, if the terminal device does not execute step 42 or step 43, it is monitored that the two-dimensional code on the display interface is closed, and at this time, step 42 or step 43 does not need to be executed any more, so that the power consumption of the display screen can be reduced, the operation of the user can be responded in time, and the user experience is optimized.

And step 45, after the two-dimensional code of the display interface is monitored to be closed, restoring the lighting time of the target pixel point in the unit time period to the initial lighting time.

And when the terminal equipment monitors that the two-dimensional code of the display interface is closed, restoring the lighting time of the target pixel point to the initial lighting time, so that the full-screen brightness restoration of the display screen is adaptive to the ambient brightness.

Wherein, if the first implementation manner in the two cases is adopted, the restoring the lighting time of the target pixel point to the initial lighting time comprises: and restoring the duty ratio of the target pixel point to the duty ratio in the current time period.

Under the PWM dimming mode, the duty ratio is higher, and the power consumption of the display screen is also higher, so that the duty ratio of the target pixel point is reduced to the original size, and the power consumption of the display screen can be reduced.

If the second implementation manner in the two cases is adopted, the restoring the lighting time of the target pixel point to the initial lighting time includes: and converting the dimming mode of the target pixel point into a PWM dimming mode, and restoring the duty ratio and the dimming frequency to the duty ratio and the dimming frequency in the current time period.

Because the power consumption of the DC dimming mode is higher than that of the PWM dimming mode, the DC dimming mode is converted into the PWM dimming mode no matter whether the target pixel point is located in a full-screen area or a display area of the two-dimensional code, and the power consumption of the display screen can be reduced.

The two-dimensional code (2-dimensional bar code) is a black and white alternate pattern which is distributed on a plane (in two-dimensional direction) according to a certain rule by using a specific geometric figure, and data symbol information is recorded. Each two-dimension code has a fixed display characteristic, and the two-dimension code can be identified according to the display characteristic of the two-dimension code. In this embodiment, the terminal device may pre-store the display characteristic information of the common two-dimensional code, and determine whether the two-dimensional code exists by detecting and matching the information displayed on the display interface in real time.

In an implementation manner, referring to fig. 5, each two-dimensional code pattern has three positioning patterns, that is, the pattern pointed by 50 in fig. 5, so in this embodiment, when monitoring whether a two-dimensional code appears on a display interface of a display screen, the terminal device can monitor whether the two-dimensional code positioning pattern appears on the display interface. Once the terminal equipment monitors that the display interface has the positioning pattern of the two-dimensional code, the terminal equipment judges that the user opens the two-dimensional code.

Based on the second condition, if the target area of the display screen is the display area where the two-dimensional code is located on the display screen, before the lighting time of the target pixel point is increased, the embodiment further discloses the following steps:

and acquiring the positioning pattern of the two-dimensional code. And acquiring the target area according to the positioning pattern. The target area is a display area of the two-dimensional code on the display screen.

In this embodiment, the display area of the two-dimensional code is the smallest display area of the two-dimensional code on the display screen. As shown in the combined figure 5, the two-dimensional code is generally rectangular, and the three positioning patterns are respectively located at three vertexes of the two-dimensional code, so that the rectangular area of the two-dimensional code can be identified through the three positioning patterns, and the smallest display area of the two-dimensional code on the display screen is identified. Aiming at the area, the lighting time of all pixel points in the unit time period is increased, when the two-dimensional code displayed by the code scanning equipment to the terminal equipment is scanned, at least all the pixel points in the area can maintain short extinguishing time, so that most of the pixel points read by the code scanning equipment can be in a lighting state, the number and the width of black twills can be reduced, and even the black twills are eliminated, so that the two-dimensional code can be quickly identified by the code scanning equipment, and the identification efficiency and the accuracy are improved.

The following are embodiments of an apparatus of the present application that may be used to perform embodiments of the methods of the present application. For details which are not disclosed in the device embodiments of the present application, reference is made to the method embodiments of the present application.

As an implementation of the foregoing embodiments, the embodiments of the present application disclose an OLED display screen dimming device applied to two-dimensional code scanning, where the device is applied to a terminal device. Referring to the schematic structural diagram shown in fig. 6, the OLED display panel dimming device disclosed in the embodiment of the present application includes: a two-dimensional code interface management module 100 and a dimming control module 200.

The two-dimension code interface management module 100 is configured to monitor whether a two-dimension code appears on a display interface of the display screen.

For example, the two-dimensional code interface management module 100 may be internally provided with a two-dimensional code scanning program, and may perform scanning detection on the display interface of the display screen in real time to determine whether the two-dimensional code appears on the display interface.

For example, the two-dimensional code interface management module 100 may be internally provided with an image analysis program, and may capture a screenshot of the display interface in real time, analyze and detect the screenshot, and monitor whether the two-dimensional code appears in real time.

After the two-dimensional code interface management module 100 monitors that the two-dimensional code appears on the display interface, the dimming control module 200 is configured to increase the lighting duration of a target pixel point in a unit time period, where the target pixel point includes each pixel point in a target area of the display screen, and the target area includes an area for displaying the two-dimensional code.

In order to clarify the solution provided by the embodiment of the present application, fig. 7 is further provided, and fig. 7 is a schematic diagram of information interaction between the two-dimensional code interface management module 100 and the dimming control module 200. Referring to fig. 7, an OLED display screen dimming device provided in an embodiment of the present application is configured to perform the following steps:

step 71, the two-dimension code interface management module 100 monitors whether the two-dimension code appears on the display interface of the display screen.

Step 72, after it is monitored that the two-dimensional code appears on the display interface, the two-dimensional code interface management module 100 generates a first trigger instruction, and transmits the first trigger instruction to the dimming control module 200.

The first trigger instruction is used for indicating that the two-dimensional code appears on the current display interface and the brightness of the target area of the display screen needs to be adjusted.

In step 73, the dimming control module 200 responds to the first trigger instruction, and increases the lighting time of the target pixel point in the unit time period.

The embodiment discloses an OLED display screen dimming device applied to two-dimensional code scanning, the device is located in terminal equipment, and through the device, as long as a user opens a two-dimensional code, the lighting time of all pixel points in a target area in a unit time period is increased aiming at the pixel points, so that the extinguishing time of each pixel point is shortened. When sweeping code equipment and scanning the two-dimensional code that terminal equipment demonstrates, short extinguishing time can all be maintained to all pixel in at least two-dimensional code place region to ensure to sweep most pixel that code equipment read and can be in the state of lighting, so can reduce the quantity and the width of black twill, eliminate the black twill even, make to sweep code equipment and can discern the two-dimensional code fast, improve recognition efficiency and rate of accuracy.

When increasing the lighting time of the target pixel point in the unit time period, the dimming control module 200 performs the following operations: and adjusting the dimming mode of the target pixel point to be a DC dimming mode.

In addition, when the dimming control module 200 increases the light-up duration of the target pixel point in the unit time period, the following operations may be further performed: and adjusting the duty ratio of the target pixel point in a unit time period to the highest duty ratio value which can be reached in a PWM dimming mode.

The dimming control module 200 first obtains a duty ratio highest value that the OLED display screen can reach in the PWM dimming mode, then increases the duty ratio of the target pixel point until the duty ratio reaches the highest value, and adjusts the target area to be brightest.

In one implementation, the display screen target area is the entire area of the display screen.

In one implementation, the display screen target area is a display area where the two-dimensional code is located on the display screen.

If the target area of the display screen is the display area where the two-dimensional code is located on the display screen, referring to the structure diagram shown in fig. 8, the OLED display screen dimming device applied to two-dimensional code scanning disclosed in this embodiment further includes: the two-dimensional code region detection module 300.

When the two-dimensional code is monitored to appear on the display interface, the two-dimensional code interface management module 100 generates a first trigger instruction and transmits the first trigger instruction to the dimming control module 200 and the two-dimensional code area detection module 300 at the same time, the two-dimensional code area detection module 300 acquires a positioning pattern of the two-dimensional code when receiving the first trigger instruction, acquires the target area according to the positioning pattern, and then sends the target area to the dimming control module 200, and the dimming control module 200 increases the lighting time of a target pixel point in a unit time period aiming at the target area based on the first trigger instruction.

In one implementation, before increasing the lighting duration of the target pixel in the unit time period in response to the first trigger instruction, the dimming control module 200 is further configured to:

the method comprises the steps of obtaining initial lighting time of a target pixel point, wherein the initial lighting time is the lighting time of the target pixel point in the current unit time period.

After the dimming control module 200 increases the lighting time of the target pixel point in the unit time period, the two-dimensional code interface management module 100 is further configured to monitor whether the two-dimensional code of the display interface is closed.

After the two-dimensional code interface management module 100 monitors that the two-dimensional code of the display interface is closed, the dimming control module 200 is further configured to set the lighting time of the target pixel point in a unit time period as the initial lighting time.

In this implementation manner, fig. 9 is further provided, and fig. 9 is a schematic diagram of information interaction between the two-dimensional code interface management module 100 and the dimming control module 200. With reference to fig. 9, the OLED display screen dimming device provided in the embodiment of the present application is further configured to perform the following steps:

step 91, the two-dimension code interface management module 100 monitors whether the two-dimension code appears on the display interface of the display screen.

Step 92, after the two-dimensional code on the display interface is monitored, the two-dimensional code interface management module 100 generates a first trigger instruction and transmits the first trigger instruction to the dimming control module 200.

Step 93, the dimming control module 200 responds to the first trigger instruction to obtain the initial lighting time of the target pixel point.

Step 94, the dimming control module 200 increases the lighting time of the target pixel point in the unit time period.

In step 95, the two-dimensional code interface management module 100 monitors whether the two-dimensional code of the display interface is closed.

In step 96, after it is monitored that the two-dimensional code of the display interface is closed, the two-dimensional code interface management module 100 generates a second trigger instruction and transmits the second trigger instruction to the dimming control module 200.

The second trigger instruction is used for indicating that the two-dimensional code does not exist in the current display interface and the brightness of the target area of the display screen needs to be recovered.

In step 97, the dimming control module 200 responds to the second trigger instruction, and sets the lighting time of the target pixel point in the unit time period as the initial lighting time.

After the user opens the two-dimensional code by using the terminal device, the two-dimensional code may be closed at any time, step 95 may be performed before step 93 and step 94, and as long as it is monitored that the two-dimensional code appears on the display interface, it is monitored whether the two-dimensional code is closed in real time. In this case, the response level of the second trigger instruction is higher than that of the first trigger instruction. For example, if the user just opens the two-dimensional code, the two-dimensional code is immediately closed, and at this time, the dimming control module 200 may not have yet responded to the first trigger instruction and receives the second trigger instruction, and in this case, the dimming control module 200 directly responds to the second trigger instruction, maintains the lighting time of the target pixel point in the unit time period as the initial lighting time, and does not adjust the brightness of the display screen, so that the power consumption of the display screen can be reduced, the user's operation can be timely responded, and the user experience is optimized.

In one implementation manner, when the two-dimensional code interface management module 100 monitors whether the two-dimensional code appears on the display interface of the display screen, the two-dimensional code interface management module is configured to: and monitoring whether the display interface of the display screen has the positioning pattern of the two-dimensional code.

When the two-dimensional code interface management module 100 monitors that the display interface has the positioning pattern of the two-dimensional code, it is determined that the user has opened the two-dimensional code. At this moment, the dimming control module 200 increases the lighting time of all pixel points in a unit time period aiming at a target area so as to avoid that the two-dimensional code is shielded by black twill when the code scanning device scans, and improve the identification efficiency and accuracy of the two-dimensional code.
