The display control method, display control apparatus, electronic device, and readable storage medium provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

An embodiment of the present application provides an electronic device, and the electronic device may be an electronic device including a display screen, including mobile terminals such as a mobile phone, a smart watch, and a tablet computer.

As shown in FIG. 1 , the electronic device includes: a main control chip 110 , a display chip 120 and a display screen 130 .

The main control chip 110 may be the main application chip of the electronic device, and the main control chip 110 may include: CPU111 (Central Processing Unit, central processing unit), GPU112 (Graphics Processing Unit, graphics processor), DRAM113 (Dynamic Random Access Memory, dynamic Random access memory), Display Controller114 (display controller) and MIPI TX115 (Mobile Industry Processor Interface, mobile industry processor interface).

In the normal display mode, the main control chip 110 is used to perform processing calculations, and the power consumption of the main control chip 110 is much higher than that of the display chip 120 .

The first interface of the display chip 120 is electrically connected to the main control chip 110, and the display chip 120 may include: CPU121, DPS122 (Digital Signal Processing, digital signal processing), a first interface and a second interface, the first interface may be MIPI RX125, The second interface may be MIPI TX126, and MIPI RX125 is electrically connected to MIPI TX115.

The display screen 130 is electrically connected to the second interface of the display chip 120, and the display screen 130 may include an LCM display module 131 (liquid crystal display module) and a touchscreen module 132 (touch control module).

Wherein, the display chip 120 is at least used to generate an on-screen image in the off-screen display mode, and send it to the display screen 130 for display. In other embodiments, the display chip 120 can also be used to The first information screen image sent by the chip is stored and sent to the display screen 130 for display.

Electronic devices can enter the always-on display mode in several ways:

First, a fourth input from the user is received, and the fourth input is used to trigger entering the screen-on-screen display mode.

This fourth input can include various forms:

(1) The fourth input can be a physical key input;

In this embodiment, the body of the electronic device is provided with a physical button corresponding to the information screen. In one product, the button may be a power-off button. When the display screen 130 of the electronic device is lit, the button is pressed. The electronic device can be switched to the active screen display mode.

(2) the fourth input can be a voice input;

In this embodiment, the electronic device may trigger the display of a screen-off display interface when receiving a voice such as "screen-off", and the screen-on-screen display interface displays a screen-off image.

(3) The fourth input may be touch input, including but not limited to click input, sliding input, and pressing input.

In this implementation manner, the user touches the target control to switch to the information screen display mode.

Second, the electronic device automatically turns off the screen according to the preset settings.

For example, when the display screen 130 is displayed normally, it is determined that the interval time from the last time the input is received reaches the target time, and the information screen display mode is automatically switched. The target time can be the default setting of the system, or the target time can be set by the user as required, including 5s, 10s, 30s, 1min, and 5min.

As shown in FIG. 5 , FIG. 6 , FIG. 7 and FIG. 9 , the on-screen image is an image displayed by the display screen 130 in the on-screen display mode, and the on-screen image may include time information and battery information, or the on-screen image may further It can include notification messages such as missed call information and push messages. Except for some areas of the screen image for displaying information, the pixels in these areas are lit, and the other areas are black, and the corresponding pixels in the black area of the display screen 130 are always off.

In the on-screen display mode, the on-screen image is generated by the display chip 120 .

Specifically, in the screen-on-screen display mode, the display chip 120 sends the first screen-on image to the display screen 130, the display screen 130 displays the first screen-on image, and the first screen-on image includes the target information of the target application; When the application program has program content updated, the display chip 120 generates a second screen-in image, and sends the second screen-in image to the display screen 130 .

At the moment of switching to the display mode of the screen, the CPU 111 or GPU 112 of the main control chip 110 generates a first screen image, and sends the first screen image and the target information of the target application to the display chip 120, and the main control chip 110 goes to sleep .

The display chip 120 sends the first screen-of-interest image to the display screen 130, and the display screen 130 displays the first screen-of-interest image.

In the case that the target application has program content update, the display chip 120 updates the screen image.

The target application may have program content updates in the following situations:

First, the target application is a clock program, and the time information on the display screen 130 changes.

The display chip reads the clock information of the clock program, and when the clock information is updated, the display chip generates a second information screen image based on the read clock information.

The time update of the clock information means that the minimum unit of the time information displayed on the display screen 130 changes. For example, in the embodiments shown in FIGS. 5, 6, 7 and 9, the time information includes: month, day, week, Hour and minute, minute is the smallest unit, when the minute information changes, the clock information has time to update, and the display chip 120 needs to update the screen image.

For example, in the embodiment shown in FIG. 5 , the current time is 12:53, and after 1 minute, the minute information changes and should display 12:54, then the main control chip 110 will not be woken up, and the display chip 120 will update the screen image, and the screen will be closed. The time information in the image is updated from 12:53 to 12:54, and the display screen 130 displays the updated on-screen image after receiving the updated on-screen image.

Second, the target application is a power monitoring program, and the power information on the display screen 130 changes.

The display chip reads the power information of the power monitoring program, and when the power information is updated, the display chip generates a second screen image based on the read power information.

In the case that the power information is displayed on the display screen 130, when the power information changes, the display chip 120 needs to update the information screen image. Changes in battery information include lower battery and higher battery.

For example, in the embodiment shown in FIG. 5, the current power is 13%. If the current power is off and the power is reduced to 12%, the main control chip 110 will not be woken up, and the display chip 120 will update the screen image, and the power in the screen image will be updated. The information is updated from 13% to 12%. After receiving the updated on-screen image, the display screen 130 displays the updated on-screen image.

Third, the target application is a program that needs to be run by the main control chip.

When the target notification message is received, the program content needs to be updated. The target notification message may include missed call information, short message messages, social application messages, etc. When the main control chip 110 receives the target notification message, only some modules of the main control chip 110 are activated. , the display chip 120 can sleep again by sending the target notification message to the display chip 120 , and the display chip 120 updates the information screen image based on the received target notification message, and sends it to the display screen 130 for display.

Since the above-mentioned update of the screen image on the display screen 130 basically does not need to start the main control chip 110, the power consumption of the main control chip 110 for drawing and frame refresh can be reduced, and only a small part of the power consumption of the display chip 120 is increased. It can effectively reduce the power consumption of the off-screen display mode.

It should be noted that, the display chip 120 generates at least the following two ways:

First, generate a complete screen image.

In this embodiment, in the on-screen display mode, every time the on-screen image on the display screen 130 needs to be updated, the display chip 120 needs to redraw the entire on-screen image.

For example, when the time information (minutes) changes, the display chip 120 needs to redraw the entire screen image, including the month, day, week, hour, and minute when the screen image is drawn, as well as battery information.

Second, only update the pixels in the area that changed.

In this embodiment, in the on-screen display mode, every time the on-screen image on the display screen 130 needs to be updated, the display chip 120 only needs to draw the changed area.

For example, when the power information changes, the display chip 120 only needs to draw the area corresponding to the power information, and send the updated information to the display screen 130 for updated display.

Of course, in some embodiments, if the target application is not updated after a period of time, the display chip 120 can also enter the sleep mode.

According to the electronic device provided by the embodiment of the present application, by adding a display chip 120 between the main control chip 110 and the display screen 130 , in the information screen display mode, the main control chip 110 basically does not need to be activated, and the display chip 120 can realize the display The refresh of the screen 130 can effectively reduce the power consumption in the off-screen display mode.

In some embodiments, as shown in FIG. 1, the display chip 120 includes a dynamic random access memory (DRAM123) and a bypass (BYPASS124), the dynamic random access memory (DRAM123) and the bypass (BYPASS124) are connected in parallel, and the dynamic random access memory (DRAM123) and the bypass (BYPASS124) are connected in parallel, and the dynamic Both the random access memory (DRAM123) and the bypass (BYPASS124) are connected between the first interface and the second interface.

As shown in FIG. 2 , in the normal (NORMAL) display mode, the CPU and GPU of the main control chip 110 draw image frame buffers (framebuffers) and transmit them through the Mobile Industry Processor Interface (MIPI) signal, and pass through the bypass of the display chip 120 . (BYPASS124) and then sent to the display screen 130 for display.

After the electronic device enters the on-screen (AOD) display mode, the main control chip 110 no longer draws and refreshes the on-screen image, and the CPU or DSP of the display chip 120 draws the image framebuffer and directly refreshes it to display on the display screen 130 through the MIPI signal.

For the Video Mode screen, since the Video Mode screen does not have DRAM, when the screen image itself does not change, the display chip 120 also continuously refreshes the frame data to the Video Mode screen according to the refresh rate of the Video Mode screen.

It should be noted that, in the related art, since the main control chip 110 needs to continuously refresh the frame data to the Video Mode screen, the electronic equipment using the Video Mode screen has no interest screen display mode. The electronic equipment of the Mode screen can also realize the screen display.

For the Command Mode screen, since the Command Mode screen is equipped with DRAM, the display chip 120 only needs to send the off screen image to the DRAM of the Command Mode screen when the screen-on-screen image itself does not change. When the Command Mode screen is refreshed, it obtains it from its own DRAM. The screen image is sufficient.

In this way, by designing the dynamic random access memory (DRAM123) and bypass (BYPASS124) connected in parallel on the display chip 120, the normal (NORMAL) display mode and the off-screen (AOD) display mode can be realized for various screens. Under the image display control, the adaptability is wider, and the scope of application of the screen display mode is increased.

In some embodiments, as shown in FIG. 3 , the electronic device may further include: a fingerprint module 140, the fingerprint module 140 is electrically connected to the third interface of the display chip 120, and the display chip 120 is used for receiving the fingerprint module 140 trigger signal to perform verification.

The fingerprint module 140 may be an off-screen fingerprint module. The fingerprint module 140 is installed at the lower part of the display screen 130 . Correspondingly, the display screen 130 displays a fingerprint control in an area corresponding to the fingerprint module 140 .

When receiving the user's input to the fingerprint control; in response to the input, the display chip 120 controls the target screen area of the display screen 130 to light up and display a solid color; when receiving the user's input to the target screen area; in response to the input , the display chip 120 performs fingerprint verification, and if the verification fails, the display screen 130 is controlled to display an off-screen image when the off-screen is displayed.

It can be understood that the target screen area is the screen area corresponding to the fingerprint module in the display screen, and the corresponding relationship may be that the projection of the target screen area and the fingerprint module along the normal of the display screen is substantially coincident.

The fingerprint verification file and the integrated verification algorithm are encrypted and stored in the display chip 120. After the fingerprint image is collected, the display chip 120 runs the verification algorithm for verification.

In the case of successful fingerprint verification, the main control chip 110 is woken up and the unlocked screen is displayed at the same time; in the case of fingerprint verification failure, the main control chip 110 is not woken up, and the display chip 120 still controls the display screen 130 to display the screen-off screen .

In this way, in the off-screen display mode of the electronic device, the display chip 120 is used to control the unlocking of the fingerprint under the screen, which can not only improve the unlocking speed of the fingerprint under the screen in the off-screen display mode, but also can cause some inadvertent finger pressing or improper pressing. In the case of fingerprint unlocking failure, it is not necessary to wake up the main control chip 110, it is completely handled by the display chip 120, and the main control chip 110 is woken up only after the unlocking is successful, which also greatly reduces the power consumption of this function. It greatly improves the security and is not easy to be cracked.

The present application also provides a display control method. The display control method can be applied to the electronic device in any of the above-mentioned embodiments. Specifically, the display control method can be executed by hardware or software in the electronic device, and is certainly not limited to the hardware or software in the electronic device. implement. The execution subject of the display control method may be an electronic device, or a control device of the electronic device, or the like.

As shown in FIG. 1 , the display control method includes: step 110 , step 120 and step 130 .

Step 110 , in the screen-on-screen display mode, the display chip sends the first screen-on image to the display screen, the display screen displays the first screen-on image, and the first screen-on image includes target information of the target application;

Regardless of whether it is a Video Mode screen or a Command Mode screen, in the off-screen display mode, the main control chip is dormant, the first off-screen image is stored in the DRAM123 of the display chip, and the DRAM123 of the display chip transmits the first off-screen image through the second interface. (MIPI TX126) to the display.

Target applications include many types:

First, the target application can be a clock program.

In this embodiment, the target information of the target application includes clock information.

For example, in the embodiments shown in FIG. 5 , FIG. 6 , FIG. 7 and FIG. 9 , the time information includes: month, day, week, hour and minute.

Second, the target application may be a power monitoring program.

In this embodiment, the target information of the target application includes power information.

Third, the target application can be other programs that need to be run by the main control chip.

In this implementation manner, the target information of the target application may include a notification message. Of course, if there is no notification message at that time, the target information of the target application may be empty.

It can be understood that, before entering the information screen display mode, the method may further include: the main control chip generates a first information screen image, and sends the first information screen image and the target information of the target application to the display chip; Chip sleeps.

The target information of the target application can be the system time of the main control chip.

After the electronic device enters the on-screen (AOD) display mode, wake up the display chip, the main control chip generates the first frame of the first screen-on-screen image, and sends it to the MIPI RX125 of the display chip through MIPI TX115, and the display chip will receive the first frame. The first screen image is stored in the DRAM 123 .

The display chip sends the received first information screen image and other second information screen images generated later to the display screen.

Step 120, in the case that the target application has program content update, the display chip generates a second information screen image, and sends the second information screen image to the display screen;

Based on different types of target applications, the above step 120 can also be in different forms:

First, the target application is the clock program.

In this embodiment, step 120 may include:

Display the clock information of the chip reading the clock program;

In the case that the clock information has time to be updated, the display chip generates a second screen image based on the read clock information, and sends the second screen image to the display screen;

Wherein, the second information screen image includes updated time information.

The above clock program runs on the display chip, and the time update of the clock program clock information indicates that the minimum unit of the time information displayed on the display screen 130 changes.

For example, in the embodiments shown in FIG. 5 , FIG. 6 , FIG. 7 and FIG. 9 , the time information includes: month, day, week, hour and minute, and minute is the minimum unit. When the minute information changes, the clock information has time to update, and the display chip generates a second screen image based on the read clock information.

For example, in the embodiment shown in FIG. 5 , the current time is 12:53, after 1 minute, the minute information changes, and the clock information is updated to 12:54. The chip 120 generates a second screen-of-interest image, and the time information in the second screen-of-interest image is updated from 12:53 to 12:54 compared with the first screen-of-interest image. Two-screen image.

It should be noted that, the clock program on the display chip 120 may be calibrated based on the system time received from the main control chip before entering the screen display mode.

In the above-mentioned embodiment, for the time update scene that requires high-frequency refresh in the screen-on-screen display mode, the control of the main control chip 110 is replaced by the control of the display chip 120, which can greatly reduce the power consumption in the screen-on-screen display mode and prolong the battery life of the electronic device. time.

Second, the target application is a power monitoring program.

In this embodiment, step 120 may include: the display chip reads the power information of the power monitoring program, and when the power information is updated, the display chip generates a second screen image based on the read power information, and displays the first screen image. The image of the two-screen screen is sent to the display screen.

In the case where the power information is displayed on the display screen 130, when the power information is updated, the display chip 120 generates a second screen image based on the read power information.

Battery information is updated to include battery decreases and battery increases.

For example, in the embodiment shown in FIG. 5, the current power is 13%. If the current power is off and the power is reduced to 12%, the main control chip 110 will not be woken up, and the display chip 120 will generate a second screen image. The battery information in the image is updated from 13% to 12% compared to the first screen-on image. After receiving the second screen-on image, the display screen 130 displays the second screen-on image.

In the above-mentioned embodiment, for the power update scenarios that require high-frequency refresh in the screen-on-screen display mode, the control of the main control chip 110 is replaced by the control of the display chip 120, which can greatly reduce the power consumption in the screen-on-screen display mode and prolong the battery life of the electronic device. time.

In this embodiment, step 120 may include:

When the main control chip receives the target notification message of the target application, the main control chip sends the target notification message to the display chip;

The display chip generates a second information screen image based on the target notification message, and sends the second information screen image to the display screen;

Wherein, the second off-screen image includes a target message control corresponding to the target notification message.

When the target notification message is received, the program content needs to be updated. The target notification message may include missed call information, short message messages, social application messages, etc. When the main control chip 110 receives the target notification message, the main control chip 110 only has some modules. After startup, the main control chip 110 sends the target notification message to the display chip 120 to sleep again. The display chip 120 generates a second screen image based on the received target notification message and sends it to the display screen 130 for display.

In other words, when the target notification message is received, the main control chip 110 does not need to be fully activated. The main control chip 110 only has the functions of receiving and forwarding, and the corresponding functional module can be activated. The display chip 120 displays corresponding prompt information on the display screen 130 , thereby reducing the power consumption of the main control chip 110 .

In the above embodiment, by updating the target notification message, the control of the main control chip 110 is replaced by the control of the display chip 120, so that when the electronic device receives the target notification message, it can remain in the off-screen display mode, which greatly reduces the off-screen display. Mode power consumption, extending the battery life of electronic devices.

There are at least the following two methods for generating the second screen-off image:

First, generate a complete second screen image.

In this embodiment, in the screen-on-screen display mode, each time a second screen-on-screen image needs to be generated, the display chip needs to redraw the entire screen-on screen image.

For example, when the time information (minutes) is updated, the display chip needs to redraw the entire second screen image.

Taking Figure 5 as an example, the display chip needs to draw the time information, power information and fingerprint controls of the screen image.

Taking Figure 6 as an example, the target notification message is a WeChat message, and the display chip needs to draw the time information, power information, target message control and fingerprint control of the information screen image, and the target message control corresponds to the WeChat message.

When the power information is updated, the same processing method is adopted.

Second, only update the pixels in the area that changed.

In this embodiment, in the screen-on-screen display mode, every time a second screen-on-screen image needs to be generated, the display chip only needs to draw the changed area.

Taking FIG. 5 as an example, the display chip 120 only needs to draw the time information of the screen-on-screen image, and light up the pixels corresponding to the time information display area with the updated time information, without redrawing the power information and fingerprint control of the screen-on-screen image. .

Taking Figure 6 as an example, the target notification message is a WeChat message, and the display chip needs to draw the target message control without drawing other unchanged information, such as time information, battery information and fingerprint control, and light up the target message according to the drawn target message control. The pixels corresponding to the display area of the control can be used.

When the power information is updated, the same processing method is adopted.

For the generated second screen image, when the display screen is a Video Mode screen, the display chip needs to continuously refresh the frame data to the Video Mode screen based on the refresh rate of the Video Mode screen; when the display screen is a Command Mode screen, The display chip sends the updated screen-of-interest image to the DRAM of the Command Mode screen. When the screen of Command Mode is refreshed, it can obtain the screen-of-interest image from its own DRAM. Before the screen image is updated again, the display chip can also enter the sleep mode to further reduce energy consumption.

Step 130 , the display screen displays the second screen-off image.

The display screen displays based on the received screen image.

When the display screen is a Video Mode screen, since the Video Mode screen does not have DRAM, the display chip continuously refreshes the frame data to the Video Mode screen based on the refresh rate of the Video Mode screen.

For example, in the off-screen display mode, the refresh rate of the display screen 130 is 30Hz, then the display chip 120 needs to read the second off-screen image stored in the DRAM 123 at a frequency of 30Hz, and refresh the second off-screen image at a refresh rate of 30Hz. Continuous refresh to display screen 130 .

It should be noted that, in the related art, since the main control chip needs to continuously refresh the frame data to the Video Mode screen, the electronic equipment using the Video Mode screen has no interest screen display mode. Electronic devices with a Video Mode screen can also achieve an on-screen display.

In the case where the display screen is the Command Mode screen, since the Command Mode screen has DRAM, the display chip 120 sends the second interest screen image to the DRAM of the Command Mode screen. When the Command Mode screen is refreshed, it obtains the second interest screen from its own DRAM. image will do.

Because in the above-mentioned various embodiments, when the screen-on-screen image on the display screen 130 is updated, it is basically unnecessary to start the main control chip 110 , which can reduce the power consumption of the main control chip 110 for drawing and brushing frames, and only increase a small part of the display chip 120 Processing power consumption, which can effectively reduce the power consumption of the off-screen display mode.

According to the display control method of the embodiment of the present application, in the off-screen display mode, the display screen can be refreshed through the display chip, basically without starting the main control chip, and the power consumption in the off-screen display mode can be greatly reduced.

In the case that the main control chip receives the target notification message of the target application, and the display screen displays the second information screen image generated by the display chip, after the step and the display screen displays the second information screen image, the method may further include:

receiving the first input from the user;

In response to the first input, the display chip generates a third screen-in image based on the target notification message, and sends the third screen-in image to the display screen;

The display screen displays the third screen image;

Wherein, the third information screen image includes the message content of the target notification message.

In this embodiment, the first input is at least used to trigger the target message control in the second screen-on-screen image, and cause the display chip to generate the third screen-on screen image.

The first input may be in various forms, including but not limited to the form of touch operation, the form of operating physical keys, or the form of voice input.

Similarly, the manner in which the display chip generates the third screen image includes at least the following two:

First, generate a complete screen image.

In this embodiment, in the full screen display mode, in response to the first input, the display chip needs to redraw the entire third full screen image.

Taking FIG. 7 as an example, the display chip needs to draw the time information, power information, message content of the target notification message, and fingerprint control of the screen image.

Second, only the message content of the target notification message is updated.

In this implementation manner, in the off-screen display mode, the display chip only needs to draw the message content of the target notification message.

Taking Figure 7 as an example, the display chip needs to draw the message content of the target notification message without drawing other unchanged information, such as time information, power information and fingerprint controls, and lights the target notification message according to the drawn message content of the target notification message. The pixel point corresponding to the display area is sufficient, the target notification message overlaps with the display area of the unlocking control, and the unlocking control is canceled.

In this way, in the display control method, the display chip can display the message content of the target notification message to the user in the information screen display mode, and the whole process does not need to wake up the main control chip, and only the display chip realizes low-power operation.

In some embodiments, the above-mentioned first input may be a sliding operation on the display interface according to the target trajectory in the screen-on-screen display mode. After receiving the sliding operation on the trajectory, the electronic device can directly display the third screen-on-screen display. image.

In other embodiments, the above steps receive the first input from the user, including:

Receive the first sub-input of the user on the target message control; in response to the first sub-input, the display chip generates a fourth information screen image, and sends the fourth information screen image to the display screen, and the fourth information screen image includes the unlocking control; receiving User's second input to unlock the control.

In this embodiment, the first input includes a first sub-input and a second sub-input.

The first sub-input is used to trigger the target message control.

The first sub-input may be touch input, including but not limited to click input, sliding input, pressing input, and the like.

In the embodiment of FIG. 6 , receiving the user's first sub-input may be receiving a user's touch operation on the target message control on the display screen.

After receiving the user's first sub-input to the target message control, the display chip generates a fourth screen-on-screen image based on the first sub-input, and when the fourth screen-off image is displayed on the display screen, the display can be unlocked in screen-on-screen mode. controls.

The unlocking controls may include various forms, including but not limited to digital password unlocking controls and pattern unlocking controls, etc. The embodiment shown in FIG. 6 shows the pattern unlocking controls.

Likewise, the ways of generating the fourth screen-of-life image include at least the following two methods:

First, generate a complete screen image.

In this embodiment, in the on-screen display mode, in response to the first sub-input, the display chip needs to redraw the entire on-screen image.

Taking Figure 6 as an example, the display chip needs to draw the time information, battery information, unlock control and fingerprint control of the screen image.

Second, only the unlock controls are updated.

In this embodiment, in the screen-on-display mode, the display chip only needs to draw the unlock control.

Taking Figure 6 as an example, the display chip needs to draw the unlocking controls, and there is no need to draw other unchanged information, such as time information, battery information and fingerprint controls, and the corresponding pixels in the display area of the unlocking controls can be lit according to the drawn unlocking controls. In the case where the display area of the unlocking control and the target message control overlaps, the unlocking control may be displayed.

The second sub-input is used to input unlocking information through the unlocking control.

The second sub-input may be a touch input, including but not limited to a click input, a slide input, a press input, and the like.

In response to the first input, the display chip generates a third on-screen image based on the target notification message, and sends the third on-screen image to the display screen, including:

In response to the second sub-input, the display chip generates a third on-screen image based on the target notification message, and sends the third on-screen image to the display screen.

In this embodiment, the second sub-input is used to input unlocking information through the unlocking control.

When the unlocking control is a digital password unlocking control, the second sub-input can be a click input; as shown in FIG. 6 , when the unlocking control is a pattern unlocking control, the second sub-input can be a sliding input.

It should be noted that the lock screen verification file and the integrated verification algorithm are encrypted and stored in the display chip, and after the second sub-input is collected, the chip verification and unlocking information is displayed.

Of course, the first sub-input and the second sub-input may also be integrated into a voice input.

In this embodiment, the terminal can trigger the display of the target notification message when receiving a voice such as "open WeChat message".

In the above-mentioned embodiment, by displaying the verification and unlocking information of the chip, it is possible to realize identity verification in the off-screen display mode to prevent information leakage, and after the verification is successful, the message of the target notification message is displayed to the user in the off-screen display mode. content, the whole process does not need to wake up the main control chip, and only realizes low-power operation through the display chip.

In some embodiments, the display control method may further include:

receiving a second input from the user, where the second input is used to wake up the electronic device;

In response to the second input, the display chip generates a lock screen image, and sends the lock screen image to the display screen;

The display shows the lock screen image.

The second input is used to wake up the electronic device and switch the electronic device to the normal display mode.

The second input may be a physical key input, such as a user pressing the power button; or the second input may be a voice input. In this embodiment, the electronic device may trigger the display lock when receiving a target voice such as "small V" screen image.

After the display screen displays the lock screen image, the method may further include:

The display chip sleeps after waking up the main control chip;

The main control chip controls the display screen through the bypass of the display chip.

In actual execution, when the user presses the power button or wakes up the electronic device by other means, the display chip controls the display to switch from the off-screen display mode to the normal display mode, and draws the first frame of the image after the bright screen is refreshed to the display. , display the lock screen interface in advance, then the display chip goes to sleep, the bypass (bypass124) of the display chip is turned on, and the main control chip is awakened at the same time, and the data source displayed on the display screen is switched back to the main control chip.

In this way, when waking up the electronic device, there is no need to wake up the main control chip first, and the electronic device is woken up by the running display chip, which can improve the speed of waking up the bright screen, the response speed of the electronic device is faster, and after waking up the main control chip, the display chip Hibernation can reduce the power consumption of the electronic device in the normal display mode.

A specific implementation of the display control method proposed by the present application will be described below with reference to FIG. 8 .

The display control method includes steps 810-840.

Step 810 , enter the information screen display mode.

The electronic device enters the screen-on display mode, the main control chip controls the display to switch to the screen-on-screen display mode, and at the same time wakes up the display chip to start working, the main control chip generates the first screen-off image, transmits the screen-on-screen image to the display chip, and converts the current screen to the display chip. The system time of the main control chip is sent to the display chip, and then the main control chip directly goes to sleep.

Step 820 , the display chip controls the display screen to display an information screen image.

The display chip will save the first information screen image sent by the main control chip in the DRAM 123 of the display chip.

For example, in the off-screen display mode, the refresh rate of the display screen is 30Hz, the display chip needs to read the first off-screen image saved in the DRAM123 at a frequency of 30Hz, and continuously refresh the first off-screen image at a refresh rate of 30Hz to the display.

In the case where the display screen is the Command Mode screen, since the Command Mode screen has DRAM, the display chip sends the first off-screen image to the DRAM of the Command Mode screen. When the Command Mode screen is refreshed, the off-screen image can be obtained from its own DRAM. . Before the screen image is updated, the display chip goes into sleep mode to further reduce power consumption.

Step 830, the display chip transmits the information screen image to the display screen according to the situation

Step 830 includes steps 831-836.

Step 831: Determine whether the clock information changes or whether a notification message is received.

If it is determined to be yes, then go to step 832, the display chip generates a second screen image and saves it in its own DRAM. If the judgment is no, go to step 833 .

After the display chip receives the system time of the main control chip, it synchronizes the clock information of its own clock program based on the system time. When the minutes of the time change, the display chip generates a second screen image, which is generated by the display chip every 1 minute. The second screen image, and exists in its own DRAM.

When the main control chip receives a target notification message (such as a short message or WeChat message), it sends the target notification message to the display chip, and the display chip generates a second information screen image and stores it in its own DRAM. The second information screen image includes and The target message control corresponding to the target notification message.

For any of the above cases, different transmission methods are formed according to the type of display screen.

Step 833: Determine whether the screen is a Video mode screen.

In the case that the display screen is the Command Mode screen, go to step 834, where the display chip reads the information screen image transmission display screen in the DRAM.

Since the Command Mode screen has DRAM, the display chip sends the off-screen image to the DRAM of the Command Mode screen. When the Command Mode screen is refreshed, it can obtain the current off-screen image from its own DRAM. Before the screen image is updated, the display chip goes into sleep mode to further reduce power consumption.

In the case that the display screen is a Video Mode screen, the process proceeds to step 835, and the display chip transmits the information screen image in the DRAM to the display screen according to the refresh rate of the display screen.

Since the Video Mode screen does not have DRAM, the display chip continuously refreshes the current screen image to the Video Mode screen based on the refresh rate of the Video Mode screen.

For example, in the off-screen display mode, the refresh rate of the display screen is 30Hz, the display chip needs to read the current on-screen image saved in DRAM123 at a frequency of 30Hz, and continuously refresh the current on-screen image at a refresh rate of 30Hz to the display.

Step 836 , whether to exit the off-screen display mode indeed.

Step 840 is entered when an input for exiting the on-screen display is received.

Step 840 , wake up the main control chip, and control the display chip to go to sleep.

When the user presses the power button or wakes up the electronic device by other means, the display chip controls the display to switch from the off-screen display mode to the normal display mode, and draws the first frame of the image after the screen is on and refreshes it to the display. Displayed, then the display chip goes to sleep, the bypass (bypass124) of the display chip is turned on, and the main control chip is woken up at the same time, and the data source displayed on the display screen is switched back to the main control chip.

According to the display control method provided by the embodiment of the present application, the display chip is used to control the screen-on-display display of the display screen, which saves a lot of power consumption and improves the speed of waking up the bright screen compared with the direct control by the main control chip. Especially for the video mode screen, the power consumption when the screen is displayed can be greatly reduced.

In addition, the display chip can be used to directly view the notification message in the information screen display mode, and the display chip draws the image and refreshes it to the display screen. Not only is it convenient for users to view messages directly on the screen, but it also saves power consumption.

The display control method may further include:

Receive a third input from the user to the fingerprint control;

In response to the third input, the display chip controls the target screen area of the display screen to light up and display a solid color, and the target screen area is the screen area corresponding to the fingerprint module in the display screen;

Display chip verification fingerprint information;

In the case that the verification of the fingerprint information fails, the display chip controls the display screen to display an off-screen image.

As shown in FIG. 3 , the electronic device to which the display control method is applied may further include: a fingerprint module 140, the fingerprint module 140 is electrically connected to the third interface of the display chip 120, and the display chip 120 is used for receiving the fingerprint module 140. The verification is performed when the trigger signal is activated.

The fingerprint module 140 may be an off-screen fingerprint module, and the fingerprint module 140 is installed at the lower part of the display screen 130 . Correspondingly, a target screen area of the display screen 130 displays a fingerprint control. The target screen area is the screen area corresponding to the fingerprint module 140 in the display screen 130, and the corresponding relationship may be that the target screen area and the projection of the fingerprint module along the normal of the display screen are substantially coincident.

The fingerprint verification file and the integrated verification algorithm are encrypted and stored in the display chip. After the fingerprint image is collected, the display chip runs the verification algorithm for verification.

In this method, the third input is used to trigger the display chip to control the display screen to light up and display a solid color at least in the target screen area, so that the fingerprint module can collect fingerprint information through the display screen. Of course, the third input is used to trigger the display chip to control the full screen lighting of the display screen, and display a solid color at least in the target screen area.

The third input may be touch input, including but not limited to click input, sliding input, pressing input, and the like. As shown in FIG. 9 , the third input may be an operation of pressing the fingerprint control.

When the fingerprint pressing area of the display screen displays solid color and highlights, the display chip controls the fingerprint module to collect the fingerprint image of the finger pressing position through the display screen.

In the case of successful fingerprint verification, the display chip wakes up the main control chip, and displays the unlocked screen at the same time. In the case of fingerprint verification failure, the display chip does not notify the main control chip, and the display chip controls the display and still displays the screen. image.

In this way, in the off-screen display mode of the electronic device, the display chip controls the fingerprint unlocking under the screen, which can not only improve the unlocking speed of the fingerprint under the screen in the off-screen display mode, but also can cause fingerprints caused by inadvertent finger pressing or improper pressing. In the case of failure to unlock, there is no need to wake up the main control chip, and it is completely handled by the display chip. Only when the unlocking is successful will the main control chip wake up, which greatly reduces the power consumption of this function. In addition, fingerprint verification on the display chip also greatly improves the security. , is not easy to be cracked.

Another specific implementation of the display control method proposed by the present application will be described below with reference to FIG. 10 .

The display control method includes steps 1010-1060.

Step 1010 , enter the information screen display mode.

The electronic device enters the information screen display mode, the main control chip controls the display screen to switch to the information screen display mode, and at the same time wakes up the display chip to start working, the main control chip generates the first information screen image, transmits the first information screen image to the display chip, and Send the current system time of the main control chip to the display chip, and then the main control chip directly goes to sleep.

In the case where the display screen is the Command Mode screen, since the Command Mode screen has DRAM, the display chip sends the first screen image to the DRAM of the Command Mode screen. When the Command Mode screen is refreshed, it obtains the first screen image from its own DRAM. That's it.

As shown in FIG. 5 , after the display screen receives the first image on the screen, the first image on the screen is displayed, and the first image on the screen includes a fingerprint control.

Step 1020: Receive user input on the fingerprint control.

During actual use, the user presses the finger on the fingerprint control.

As shown in FIG. 9 , the user presses a finger against the fingerprint control, and when the display screen detects that the finger is pressed, a notification message is sent to the display chip through the interrupt pin.

Step 1030: The display chip controls the target screen area of the display screen to light up and display a solid color.

After receiving the above notification message, the display chip directly controls the target screen area of the display screen to light up and display a solid color, and at the same time update the displayed image, that is, draw the target screen area corresponding to the fingerprint module as a solid color and refresh it to the display screen.

Compared with the above method, the operation is faster after waking up the main control chip, so that the fingerprint image can be collected earlier.

Step 1040: The display chip controls the fingerprint module to collect a fingerprint image.

When the target screen area of the display screen is lit and displayed as a solid color, the display chip controls the fingerprint module to collect the fingerprint image of the target screen area through the display screen.

Step 1050: The display chip verifies the collected fingerprint image.

The fingerprint verification file and integrated verification algorithm are encrypted and stored in the display chip. After the fingerprint image is collected, the display chip is verified through the verification algorithm.

Step 1060: Wake up the main control chip and display the screen after the unlocking is successful at the same time.

If the fingerprint verification is successful, the main control chip will be woken up, and the unlocked screen will be displayed at the same time. If the fingerprint verification fails, the main control chip will not be notified, and the display chip will control the display to still display the screen image.

In this way, in the off-screen display mode, the fingerprint unlocking under the screen is controlled by the display chip, which can not only improve the unlocking speed of the fingerprint on the screen in the off-screen display mode, but also for some inadvertent finger pressing, or improper pressing causes the fingerprint to fail to unlock. In this case, there is no need to wake up the main control chip, it is completely handled by the display chip, and the main control chip can be woken up only after the unlocking is successful, which greatly reduces the power consumption of this function. In addition, the fingerprint verification on the display chip also greatly improves the security, and it is not easy to been cracked.
