Detailed Description

The present application is further described with reference to the following detailed description and the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. In addition, for convenience of description, only a part of structures or processes related to the present application, not all of them, is illustrated in the drawings. It should be noted that in this specification, like reference numerals and letters refer to like items in the following drawings.

Illustrative embodiments of the present application include, but are not limited to, display methods, display control apparatus, media, device displays, and electronic devices, among others.

Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. It will be apparent, however, to one skilled in the art that some alternative embodiments may be practiced using the features described in part. For purposes of explanation, specific numbers and configurations are set forth in order to provide a more thorough understanding of the illustrative embodiments. It will be apparent, however, to one skilled in the art that alternative embodiments may be practiced without the specific details. In some other instances, well-known features are omitted or simplified in order not to obscure the illustrative embodiments of the present application.

For various electronic devices with displays, such as mobile phones, the AOD function enables a user to obtain some basic information, such as time, date, power, etc., in real time without lighting up the screen, as shown in fig. 1.

For various electronic devices such as mobile phones, especially for electronic devices using OLEDs as displays, AOD is a very convenient and practical function because OLEDs can control individual pixels to display content, and when the screen displays black, the black area does not need to emit light, thus not consuming too much power as full bright display. However, since the AOD function makes a part of the display screen always bright, it is still very power consuming. Therefore, many electronic devices default to turning off the AOD function in order to increase endurance.

Embodiments of the present application are directed to provide a screen-off display control system to reduce display power consumption of an electronic device in an AOD state. Embodiments of the present application may be applied to various devices including a display, for example, various electronic devices such as a mobile phone, a smart television, a desktop computer, a laptop computer, a tablet computer, a portable game machine, a portable music player, a reader device, a head mounted display, and the like. In some implementations, the electronic device can be a wearable device that can be worn by a user. For example, the electronic device may be or be part of a smart watch, bracelet, jewelry, or glasses, etc. In various implementations, the user may view the message on a display of the electronic device or may access the message via a speaker or other output device of the electronic device. For example, according to some embodiments of the present application, a user may view information on a display of a cell phone, smart watch, or smart bracelet. According to further embodiments of the present application, a user may access a message via a headset, a speaker, a haptic feedback device, or the like, coupled to or part of an electronic device.

Fig. 2 shows a structural example of a display control system 200 according to an embodiment of the present application, and the display control system 200 can be applied to various electronic devices with displays such as a mobile phone.

As shown in fig. 2, the display control System 200 may include a System On Chip (SOC) 210 and a display 230, where the SOC210 may serve as a master of the display control System 200 and may send display data to the display 230 and control display activities of the display 230. In some embodiments of the present application, the main control device of the display control system 200 may also be implemented in a manner other than SOC.

A Central Processing Unit (CPU) 211, a Graphics Processing Unit (GPU) 212, a sensor HUB (HUB)213, a display stream compression module 214, a first display data interface 215, and the like may be included in the SOC 210. The display 230 may include a display control device 220 and a display panel 240, and the display control device 220 may further include a second display data interface 221, an 1/3RAM222, a decompression module 223, a format mapping module 225, a 1bit RAM226, a driving mode mapping module 227, a display panel driving circuit 224, and the like.

The CPU 211 in the SOC210 is a final execution unit for information processing and program execution, which is an operation and control core of the computer system. The GPU 212 is used as a core processor of a dedicated graphic for performing image and graphic related operation work, graphics rendering, and the like. The sensor HUB 213 is used to interface and process data from the various sensors.

According to some embodiments of the present application, the CPU 211 may be configured to process the display data, and after the CPU 211 processes one or more frames of the display data, the display data may be placed in the memory. In a mobile phone, a Random Access Memory (RAM) 231 is usually used as a Memory for the SOC210, for example, a Low Power Double Data Rate Synchronous Dynamic Random Access Memory (LPDDR SDRAM) may be used. In various embodiments of the present application, a portion or all of the RAM231 may be integrated into the SOC210, or may be independent of the SOC210 and invoked by the SOC 210.

Since the integrated RAM inside the display 230 such as the OLED is high in cost, in order to reduce the cost, the display data stored in the RAM may be compressed before being transmitted to the display 230, thereby reducing the size of the display data, so that the RAM inside the display may be made smaller, thereby reducing the cost of the display.

The Compression module 214 may employ various Compression techniques to compress the Display data, and according to some embodiments of the application, in the handset, the Compression module 214 typically employs Display Stream Compression (DSC), which is an image Compression standard defined by Video Electronics Standards Association (VESA), which is a widely accepted lightweight codec standard for Display links with low cost, short latency, and visual lossless. The efficient coding technology of DSC comprises advanced prediction, historical color index, simple entropy coding, good rate control and the like, and the compression rate is 1/2 or 1/3. Currently, the compression ratio of 1/3 is typically used to allow the RAM inside the display 230 to be smaller. Since the compressed data size is 1/2 or 1/3, the RAM size corresponding to the display control device 220 is typically referred to as 1/2RAM or 1/3RAM, respectively.

The compressed display data may be sent to the display control device 220 in the display 230 through the display data interface. In an embodiment of the present application, the Display data Interface may adopt a Display Serial Interface (DSI), where the DSI is a specific Interface defined by a Mobile Industry Processor Interface (MIPI) alliance for the Display portion. The DSI transmits pixel information or instructions in a serial manner, and enjoys its own independent communication protocol during transmission, including packet format and error correction and detection mechanism.

As shown in fig. 2, in the case of using DSI as a display data interface in the system 200, the SOC210 side transmits display data compressed by the compression module 214 to the display 230 through the first DSI 215, and the display control device 220 receives the display data through the second DSI 221 corresponding to the first DSI 215 of the SOC side on the display 230 side.

It should be understood that the DSI interface is only used as an example in the embodiments of the present application, and in other embodiments of the present application, other display data interfaces may be used to transmit display data, and examples of the other display data interfaces include but are not limited to: namely, a Low Voltage Differential Signaling (LVDS) Interface, a High Definition Multimedia Interface (HDMI), a Transistor-Transistor Logic (TTL) Interface, etc.

The display data received through the second DSI 221 may be stored in RAM integrated within the display 230, in the embodiment of the present application 1/3RAM222 is taken as an example of RAM integrated in the display 230. 1/3RAM222 may employ Static Random Access Memory (SRAM) according to some embodiments of the present application.

The decompression module 223 may be used to decompress 1/3 the display data in the RAM222 and send it to the display panel driver circuit 224. The decompression algorithm used in the decompression module 223 needs to correspond to the compression algorithm used in the compression module 214, and for example, when the display data is compressed by the compression module 214 using the DSC standard, the decompression module 223 decompresses the display data using the DSC standard as well.

The driving circuit 224 is configured to scan the decompressed display data and drive the display panel 240 such that an image corresponding to the display data is displayed on the display panel 240. According to some embodiments of the present disclosure, the display panel 240 may be an Active-matrix organic light-emitting diode (AMOLED) panel, and the corresponding display 230 is an AMOLED display. In other embodiments of the present application, the Display 230 may also be other types of displays, such as a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED) Display, a Micro-LED (Micro-LED) Display, and the like. The display panel driving circuit 224 may have various structures for different displays 230, and the present application is not limited thereto.

Using the

second DSI

221, 1/3RAM222, decompression module 223, display panel drive circuit 224, and display panel 240, the display 230 can perform display in the normal display mode, displaying display content corresponding to the display data received from the SOC210 on the display panel 240. In the practice of the present application, the normal display mode may refer to a display in which the screen is fully lit.

With the display control system 200, in the normal display mode, the electronic device may detect whether the display content needs to be updated through the CPU 211, and when the display content is updated, the processing flow of the display data may include:

the CPU 211 finishes processing one frame of display data → the display data is stored in the RAM231 → the DSC compression module 214 reads the display data in the RAM231 and compresses it to the original 1/3 size → the display data in the RAM231 is sent to the display 230 through the first DSI 215 → the display 230 receives data through the second DSI 221 → the received display data is stored in the 1/3RAM222 → the DSC decompression module 223 reads the display data in the 1/3RAM222 for data decompression → the decompressed display data is sent to the drive circuit 224 → after being scanned by the drive circuit 224, the corresponding image is displayed on the display panel 240.

When the display content does not need to be updated, the data held in the RAM222 of 1/3 is read from the RAM222 of 1/3 and the display is decompressed, that is:

the DSC decompression module 223 reads 1/3 the display data in the RAM222 for data decompression → the decompressed display data is sent to the drive circuit 224 → after scanning by the drive circuit 224, the corresponding image is displayed on the display panel 240.

In the above processing flow of display data, when the display data is not updated, the SOC210 side does not need to work, and a part of the display power consumption can be reduced, but the DSC decompresses 1/3RAM222, which still consumes a large amount of power, especially for AOD scenes.

In the AOD scene, generally, the time taken to display the content update is small, and the time taken to display the content non-update state (i.e., content holding state) is long. For example, the AOD scene is usually used to display basic information such as time, power, etc. In an AOD scenario where time is displayed, the time displayed is typically accurate to the order of minutes, e.g., as shown in fig. 1, the display time is "21: 11". In this case, the display data update is mainly caused by the lapse of time, and the time of display changes once every 1 minute, that is, the display contents need to be updated only once within 1 minute.

Assuming that the refresh rate of the display of the handset shown in fig. 1 is 60 frames/second, the data is updated once within 1 frame, then within 1 minute:

the time taken for display content update is only: (1/60) 16.66 ms;

the time for the display content retention state is: 1 minute- (1/60) second 59983.34 milliseconds.

If the refresh frequency of the display 230 is higher, the content will be updated less often and the content will be maintained longer.

If data is displayed in the AOD by using such a normal display mode, it is necessary to repeatedly decompress 1/3 the data in the RAM222 in the content holding state, which is very power consuming.

Therefore, according to some embodiments of the present application, in the display 230, a format mapping module 225, a 1-bit RAM226 and a driving manner mapping module 227 are provided, and by using these modules, the format of each pixel in the display data is mapped to 1bit and stored in the 1-bit RAM226, and when the subsequent display content is not updated, the display data can be directly read from the 1-bit RAM226 to drive the display, so that the display data in the AOD mode no longer needs the compression and decompression processes.

The format mapping module 225 is configured to map the data format of each pixel of the initial display data sent from the SOC210 side to 1 bit.

In general, the data format of each pixel of the initial display data transmitted from the SOC210 side is 24 bits (bit) (including red (R)8bit, green (G)8bit, and blue (B)8bit), and different colors can be displayed by mixing RGB. 24 bits can display 2^24 ^ 16777216 colors. Of course, in some embodiments, the format of the display data received by the display may not be RGB format, or 24bit, but other formats, which is not limited in this application.

For AOD, users usually only need to know some basic information, and monochrome display is enough for users to conveniently acquire the basic information. Therefore, only one color can be displayed without 16777216 colors, and 1bit is used to represent the ON (ON) state and the OFF (OFF) state of the corresponding pixel, and whether the corresponding pixel is displayed or not is enough, so that the data format of each pixel can be mapped from multiple bits (e.g. 24 bits) to 1 bit. And stores the mapped 1-bit display data of each pixel point into the 1-bit RAM 226.

Mapping the 24-bit format to the 1-bit format may be accomplished in various ways. According to some embodiments of the present application, the received initial display data may be mapped based on a value of at least one of the components of each pixel in the color space in the initial display data, and the initial display data may be mapped from a 24-bit format to a 1-bit format. The color space (also called color model) may include, but is not limited to: red, Green, Blue, RGB space, luminance and chrominance (usually YUV) space, Hue, Saturation, Intensity (Hue, Saturation, HSI) space, Hue, Saturation, Value (Hue, Saturation, HSV) space, etc.

For example, display data (e.g., RGB format display data) may be converted to YUV format, where the "Y" component represents brightness (Luma), i.e., a gray scale value; the "U" component and the "V" component represent Chrominance (Chroma or Chroma), the highest bit of the Y component of each pixel is extracted, and the highest bit of Y is 0, so the 1-bit format mapping result of the corresponding pixel is 0; the highest bit of Y is 1, and the 1-bit format mapping result of the corresponding pixel is 1.

For another example, the highest bit of the component values of R, G, B three components of each pixel of the display data in RGB format may be taken directly (or after converting the display data into RGB format), and then the highest bit of R, G, B may be subjected to or operation, or the result of the or operation may be the result of 1-bit format mapping. Then, as long as the highest bit of one entry in R, G, B is 1, the 1-bit format mapping result of the corresponding pixel is 1; r, G, B, the most significant bit is 0, the 1-bit format mapping result of the corresponding pixel is 0.

The 1-bit RAM226 is used for storing the result of the format mapping performed by the format mapping unit 225. The 1-bit RAM does not have a 1-bit storage size of the 1-bit RAM226, but means that each pixel stored corresponds to a 1-bit size. Thus, the size of the 1-bit RAM226 is related to the resolution of the display. For example, for a display with 2400 x 1080 resolution, the size of the 1-bit RAM226 would be 2400 x 1080 ═ 2592000 bits.

According to some embodiments of the present application, the 1-bit RAM226 may be separate and independent from the 1/3RAM222 or integrated with the 1/3RAM222, or, in some embodiments, a portion of the 1/3RAM222 may be used directly as the 1-bit RAM226, since the normal display mode and the AOD mode do not occur simultaneously.

The driving manner mapping module 227 is used for enabling the display panel 240 to present different colors. Although 1bit can only represent ON and OFF of the corresponding pixel, that is, whether there is display, the driving mode mapping module 227 can make the pixel in the ON state ON the display screen display different colors according to different situations, which may be white, red, green, etc., and theoretically there may be 2^24 ^ 16777216 colors. According to some embodiments of the present application, the driving manner mapping module 227 may present the related content in a color selected by the user according to the setting of the user, or display a color by default, or the like. However, with this 1-bit RAM design, all pixels can only display the same color, i.e., red, yellow, etc., at the same time, and cannot display a plurality of different colors, respectively, when displaying.

By using the format mapping module 225, the 1-bit RAM226, and the driving method mapping module 227, the display 230 can perform display in the AOD mode with low power consumption, and display content corresponding to display data received from the SOC210 is displayed on the display panel 240. Meanwhile, since the display 230 side no longer needs to store the display data into the 1/3RAM222, the SOC210 side also does not need to perform the compression operation any more.

Therefore, after the electronic device is turned off, the electronic device may be put into the AOD mode by using the display control system 200 shown in fig. 2, and when the CPU 211 of the electronic device detects that the display content is to be updated, the processing flow of the display data may include:

the CPU 211 finishes processing the display data of one frame → the display data is stored in the RAM231 → the display data is sent to the display 230 through the first DSI 215 → the display 230 receives the display data through the second DSI 221 → the received display data is mapped from 24bit to 1bit through the format mapping module 225 → the mapped display data is stored in the 1bit RAM226 → the driving mode mapping module 227 reads the display data from the 1bit RAM226 and converts the display data into a format suitable for driving the display → the driving circuit 224 scans the display data and drives the display panel 240 → the display panel 240 to display the corresponding image according to the display color selected by the user.

When the CPU 211 of the electronic device detects that the display content does not need to be updated, the data held in the 1-bit RAM226 only needs to be read from the 1-bit RAM226 and displayed:

reading the display data from the 1-bit RAM226 → according to the display color selected by the user, the driving mode mapping module 227 converts the data into a format suitable for the driving of the display → the driving circuit 224 scans and drives the display panel 240 → the display panel 240 displays the corresponding image.

As can be seen from fig. 2, the system 200 provided in the embodiment of the present application provides two different display data processing channels, one is the data processing channel 271 in the normal display mode shown by the gray arrow, and the other is the data processing channel 272 in the AOD mode shown by the white arrow.

In the normal display mode, with the normal channel 271 shown by a white arrow, if the display data needs to be updated, the steps of compressing, storing, decompressing, driving and displaying, etc. are sequentially performed. If the display data does not need to be updated, the display data is only needed to be read from the 1/3RAM222 and then decompressed and displayed, and the DSI interface 221 of the SOC210 and the display 230 does not work, so that the power consumption in the display process can be effectively reduced.

In the AOD mode, the 1/3RAM222 and the decompression module 223 consume a large amount of power because the time taken for display content to be updated is small, and the time taken for display content to be in a non-updated state (i.e., a content holding state) is long. Therefore, in the AOD mode, the format of the display data of each pixel can be mapped from 24bit to 1bit by using the AOD channel 272 shown by a white arrow, so that the display data of the AOD does not need to be compressed and decompressed any more, and does not need to be stored in the 1/3RAM222, thereby further reducing the power consumption of the AOD.

In the above, although the AOD mode in the embodiment of the present application is described by taking an example of mapping the format of the display data of each pixel from 24 bits to 1bit, according to some other embodiments of the present application, the format of the display data of each pixel may also be mapped to multiple bits, so that multiple colors can be displayed on the display 230 in the AOD mode.

In the case where the format mapping unit 225 maps the format of the display data of each pixel to n bits, the corresponding 1-bit RAM226 may be replaced with an n-bit RAM to store the result of the format mapping performed by the format mapping unit 225. The n-bit RAM stores n bits for each pixel. Thus, the size of the n-bit RAM is related to n times the resolution of the display. For example, for the 2400 x 1080 resolution display mentioned above, the size of the n-bit RAM storing the mapped display data is n x 2400 x 1080 ═ 2592000 x n bits. For example, in some embodiments, the format of the display data for each pixel may be mapped to 2 bits so that at least two different colors may be displayed on display 230, such as the AOD shown in FIG. 1, the upper time "21: 11" may be displayed in one color and the lower date "1 month, 5 days, sunday" may be displayed in another color. Through the mode, on one hand, the display effect under the AOD mode can be enriched, and meanwhile, the power consumption can be saved to a certain extent.

It should be noted that the structure of the display control system 200 shown in connection with fig. 2 is merely an example, and does not constitute a specific limitation to the display control system 200. In other embodiments of the present application, the display control system 200 may include more or fewer modules than shown, or combine certain modules, or split certain modules, or a different arrangement of modules. Furthermore, some of the modules or components shown in fig. 2 may be implemented in hardware, software, or a combination of software and hardware.

An example of a process for displaying content by using the display control system 200 shown in fig. 2 in an electronic device with a display will be described in detail below with reference to fig. 3.

As shown in fig. 3, first, S1: it is determined whether the display 230 of the electronic device is off. The screen-off of the display 230 may be triggered by various operations, for example, the display screen detects a touch operation for turning off the screen of the electronic device, a power key is pressed, the electronic device receives a voice screen-off message, and the like, which is not limited herein.

After the display is turned off, S3: the CPU 211 may transmit a command to the display 230 to enter the AOD mode in which a portion of an area on a screen of the electronic device displays some information, to control the electronic device to enter the AOD mode.

S5: the CPU 211 detects whether there is a signal that triggers the electronic device to exit the AOD mode. According to some embodiments of the present application, the signal may include, but is not limited to, the electronic device receiving a message or notification that the screen needs to be illuminated to notify the user, or the like.

In the event that the determination at S5 is NO, there is no signal triggering the electronic device to exit AOD mode, the method continues to S7 and S9: the CPU of the electronic device starts sending display data to the display 230. Specifically, referring to fig. 2, on the SOC210 side, after the CPU 211 has processed the display data, the display data is stored in the RAM231, and then the display data in the RAM231 is transmitted to the display 230 through the first DSI 215.

Subsequently, the display 230 side may perform S11: the received display data is mapped to a 1bit per pixel format. Mapping the received display data into the 1-bit format may be implemented in various manners mentioned above, for example, converting the display data in the RGB format into the YUV format mentioned above, extracting the highest bit of the brightness Y of each pixel, or performing an or operation on the highest bit of R, G, B of each pixel, which is not described herein again. The operation of S11 may be performed by format mapping module 225 shown in fig. 2.

S13: and storing the display data after format mapping. As shown in FIG. 2, display data mapped to a 1-bit per pixel format may be stored in a 1-bit RAM226 integrated into the display 230.

According to some embodiments of the present application, the specific color may be determined according to a setting of a user, or a specific color may be displayed by default, etc., and the operation of S15 may be performed by the aforementioned driving manner mapping module 227.

S17: the converted display data is sent to the display panel driving circuit 224.

S19: the driving circuit 224 scans the received display data and displays the corresponding display contents of the specific color on the display panel 240.

S21: it is determined whether the display content is to be updated, and this operation may be performed by the CPU 211 on the SOC210 side in fig. 2. The CPU 211 may determine whether to update the display contents according to the current time, the device power amount, and the like, which need to be displayed. For example, in the example shown in fig. 1, the display content needs to be updated when the minute position of time needs to jump, otherwise no update is needed. As another example, in the case where the power amount of the electronic device is shown in the AOD mode, the power amount of the electronic device may be detected and the display content may be updated every 1% drop of the power amount.

If the determination in S21 is no, that is, if the display content is not updated, the process returns to S15, the display data after format mapping in the 1-bit RAM226 is directly read and converted for display, and operations such as data transmission and format mapping before S15 are not required to be repeatedly executed, and the module executing the corresponding operations may enter a power saving state.

If it is determined as yes in S21, that is, if the display content is to be updated, the flow returns to S5: it is detected whether there is a signal that triggers the electronic device to exit the AOD mode.

In the case where the determination in S5 is no, in the case where there is no signal triggering the electronic apparatus to exit the AOD mode, the method proceeds to S7 and subsequent operations.

Whereas if it is determined in S5 that it is yes, for example, the electronic apparatus receives a message or notification or the like that the screen needs to be lit to notify the user, the method may proceed to S2: the CPU 211 may send a command to the display 230 to exit the AOD mode and enter the normal mode, causing the electronic device to enter the normal display mode.

Subsequently, S4: detecting whether a signal triggering the electronic equipment to exit the normal display mode exists. For example, the electronic device is turned off.

In the event that the determination at S4 is no, there is no signal triggering the electronic device to exit the normal display mode, the method continues to S6: the CPU of the electronic device processes the display data and stores it in the RAM. Specifically, referring to fig. 2, on the SOC210 side, after the CPU 211 finishes processing the display data, the display data is stored in the RAM 231.

Subsequently, S8: the display data is compressed, for example, by the DSC standard described above, the display data in RAM231 is compressed to 1/3 size.

S10: the SOC210 may send the compressed display data to the display 230 through the first DSI 215.

Subsequently, on the display 230 side, S12: the received display data is stored in RAM (e.g., 1/3RAM222 in fig. 2) of display 230.

S14: the display data in the RAM222 is read 1/3 and decompressed, and when the display data is compressed by DSC, decompression is performed similarly by the DSC standard.

S16 and S18: the decompressed data is sent to the driver circuit 224, and the driver circuit 224 scans the received display data and displays the corresponding image on the display panel 240.

S20: it is determined whether the display content needs to be updated, and this operation may be performed by the CPU 211 on the SOC210 side in fig. 2.

If the determination in S20 is no, that is, if the display content is not updated, the process returns to S14, and the compressed display data in the RAM222 of 1/3 is directly read and decompressed to drive the display, and the operations such as data compression and transmission before S14 are not repeated, and the module performing the corresponding operation may enter the power saving state.

If it is determined as yes in S20, that is, if the display content is to be updated, the flow returns to S4: detecting whether a signal triggering the electronic equipment to exit the normal display mode exists.

If the determination in S4 is no, and if there is no signal triggering the electronic apparatus to exit the normal display mode, the method continues to S6 and subsequent operations.

Whereas if the determination in S4 is yes, e.g., the electronic device is turned off, the method may continue to S3: the CPU 211 may send a command to the display 230 to enter AOD mode to control the electronic device to enter AOD mode.

The display control process of some embodiments of the present application and the different operations in the normal display mode and the AOD mode in the process are described above in connection with fig. 2 and 3. According to some embodiments of the application, the electronic equipment is controlled to enter different modes according to different states of the electronic equipment, so that the power consumption of the display process is reduced as much as possible in the normal display function and the AOD function, and the cruising ability of the electronic equipment is improved. Although the AOD mode is taken as an example in the above method, according to some embodiments of the present application, the above scheme of mapping the initial display data into 1-bit (or multiple-bit) display data and then displaying the data may be applied to other display modes.
