[0053] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The screen-off display method provided by the present application can be applied to an application environment as Figure 1 shown. The screen-off display method is applied to a screen-off display system. The screen-off display system includes a projection device 102 and an intelligent electronic device 104. Among them, the intelligent electronic device 104 includes one or more. The projection device 102 communicates with each intelligent electronic device 104 through a network. When the projection device 102 is in the screen-off state, the projection device 102 obtains the user's current information to be displayed and the user status monitored in real time, where the information to be displayed includes the display time; further, a corresponding screen-off display mode is determined as the target screen-off display mode according to the display time, the user status and the information to be displayed, and finally the information to be displayed is displayed through the target screen-off display mode. Among them, the projection device is a device that can project images or videos onto a screen or a background wall, such as a projector; the intelligent electronic device can be a terminal or a server. The terminal can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0055] The projection device 102 includes one or more sequentially arranged sub-light sources 20. As Figure 2A shown, the figure shows a plurality of sub-light sources 20, and the sub-light sources 20 are sequentially arranged corresponding to each other on the LCD screen. In an embodiment, as Figure 2BSchematic diagram of a liquid crystal display lighting module shown. The liquid crystal display lighting module mainly includes a metal substrate 1, an LED lamp bead 2, a first free-form compound eye lens 3, a light-shielding plate 4, a second free-form compound eye lens 5, and an LCD display screen 6. The Lambertian characteristic light beam emitted from the LED lamp bead 2 passes through the first free-form compound eye lens 3 and the second free-form compound eye lens 5 in sequence, and then projects an illumination light beam with uniform illuminance and collimated direction on the LCD display screen 6.

[0056] As Figure 2C Schematic diagram of the light traveling when a single LED lamp bead 201 works shown. The light rays with a smaller emission angle (the angle between the emitted light ray and the optical axis) emitted from the LED lamp bead 201 pass through the sub-compound eye 301 and the sub-compound eye 501 in sequence and then reach the corresponding local area on the LCD display screen 6; while the light rays with a large angle (about 70°) emitted from the LED lamp bead 201 directly reach the light-shielding plate 4 after passing through the first free-form compound eye lens and are absorbed by it. At this time, the LED lamp bead 201, the sub-compound eye 301, and the sub-compound eye 501 form a sub-light source 20.

[0057] In one embodiment, as Figure 3 shown, a method for screen-off display is provided. In this embodiment, the method is mainly exemplified by being applied to the Figure 1 projection device 102 therein.

[0058] Step 202, when the projection device is in the screen-off state, obtain the user's current information to be displayed and the user state monitored in real time; the information to be displayed includes the display time.

[0059] Among them, the screen-off state refers to the state when the projection device turns off the screen. The information to be displayed includes the display time. The information to be displayed is the content that the projection device is going to display, which can be a picture or a video. The user state includes the presence state, absence state, active state, and sleep state.

[0060] Specifically, when the projection device is in the screen-off state, the projection device obtains the user's current information to be displayed and the user state monitored in real time, where the information to be displayed includes the display time. In one embodiment, the user state can be monitored by setting several sensors in the environmental area around the projection device, and the user state is monitored in real time through the sensors. The sensors can be infrared sensors, temperature sensors, photoelectric sensors, and are not limited herein, as long as they can monitor the user state in real time.

[0061] In one embodiment, the method for the projection device to enter the screen-off state may be as follows: when it is detected that the user operates at a preset position of the projection device, enter the screen-off state; it may also be to obtain the real-time time of the internal system, and when the real-time time reaches the preset time of the user, the projection device enters the screen-off state; it may also be that after the projection device finishes projecting a picture or video, it automatically enters the screen-off state; here, there is no specific limitation on entering the screen-off state.

[0062] Step 204: Determine the screen-off display mode corresponding to the information to be displayed as the target screen-off display mode according to the display time, user status, and information to be displayed.

[0063] Among them, the screen-off display mode refers to the display mode for displaying the information to be displayed when the projection device is in the screen-off state. The screen-off display modes include the standard display mode, the high-brightness monochromatic high-refresh display mode, the high-brightness monochromatic low-refresh display mode, the low-brightness high-refresh monochromatic display mode, the low-brightness low-refresh monochromatic display mode, and the ultra-low-brightness monochromatic low-refresh display mode. The target screen-off display mode is the display mode for the projection device to display the information to be displayed in the screen-off state, and it can be any one of the following 6 display modes.

[0064] Standard display mode: The total light source power of the target sub-light source is 100%, that is, the target sub-light source uses full-color display. For example, if there are N sub-light sources, in the standard display mode, the light source power consumed by each sub-light source is 1 / N of the total light source power consumption.

[0065] High-brightness monochromatic high-refresh display mode: The target sub-light source uses RGB for combined display or independent display, displaying a single color, where RGB are respectively driven with a light source power of 30% to 100%. The light source driving frequency of the target sub-light source is 0 to 20HZ, that is, the target sub-light source is always on or has a low refresh frequency. The display unit refresh frequency in the display unit parameters is the normal refresh frequency, and the display unit display parameter is the high-transparency mode, where the high-transparency mode is an image display mode with a gray scale value of 0. For example, if there are N sub-light sources, in the high-brightness monochromatic high-refresh display mode, the light source power consumed by each sub-light source is 1 / 3N * 30% to 1 / 3N * 100% of the total light source power consumption.

[0066] High-brightness monochromatic low-refresh display mode: The target sub-light source combines or independently displays using RGB, showing a single color, where RGB are respectively driven with light source powers of 30% to 100%. The light source driving frequency of the target sub-light source is 0 to 20 HZ, that is, the target sub-light source is always on or has a low refresh frequency. The display unit refresh frequency in the display unit parameters is a low refresh frequency, and the display unit display parameter is a high-transparency mode. For example, if there are N sub-light sources, in the high-brightness monochromatic high-refresh display mode, the light source power consumption of each sub-light source is 1 / 3N * 30% to 1 / 3N * 100% of the total light source power consumption. And the power consumption of the display unit part is also correspondingly reduced, having obvious energy-saving value.

[0067] Low-brightness high-refresh monochromatic display mode: The target sub-light source combines or independently displays using RGB, showing a single color, where RGB are respectively driven with light source powers of 20% to 80%. The light source driving frequency of the target sub-light source is 0 to 20 HZ, that is, the target sub-light source is always on or has a low refresh frequency. The display unit refresh frequency in the display unit parameters is a high refresh frequency, and the display unit display parameter is a high-transparency mode. The brightness of the projection screen of the projection device is 2 to 5 times the ambient illumination; for example, if there are N sub-light sources, in the high-brightness monochromatic high-refresh display mode, the light source power consumption of each sub-light source is 1 / 3N * 20% to 1 / 3N * 80% of the total light source power consumption.

[0068] Low-brightness low-refresh monochromatic display mode: The target sub-light source combines or independently displays using RGB, showing a single color, where RGB are respectively driven with light source powers of 20% to 80%. The light source driving frequency of the target sub-light source is 0 to 20 HZ, that is, the target sub-light source is always on or has a low refresh frequency. The display unit refresh frequency in the display unit parameters is a low refresh frequency, and the display unit display parameter is a high-transparency mode. For example, if there are N sub-light sources, in the high-brightness monochromatic high-refresh display mode, the light source power consumption of each sub-light source is 1 / 3N * 20% to 1 / 3N * 80% of the total light source power consumption.

[0069] Ultra-low-brightness monochromatic low-refresh display mode: The target sub-light source combines or independently displays using RGB, showing a single color. Among them, the three RGB light sources are respectively driven with light source powers of 5% to 20%; among them, the driving frequency of the sub-light source is 0 to 20 HZ, that is, the target sub-light source is always on or in a low-refresh mode; the display unit refresh frequency in the display unit parameters is a low refresh frequency, and the display unit display parameter is a high-transparency mode. For example, if there are N sub-light sources, in the high-brightness monochromatic high-refresh display mode, the light source power consumption of each sub-light source is 1 / 3N * 5% to 1 / 3N * 20% of the total light source power consumption. The energy-saving effect is quite obvious.

[0070] Specifically, after obtaining the information to be displayed, the projection device further determines the screen-off display mode corresponding to the information to be displayed, as the target screen-off display mode, based on the display time carried by the information to be displayed, the user status monitored in real time by the sensor, and the information to be displayed.

[0071] In one embodiment, when the display time is the sleep time and the user status is the sleep state, it is determined that the screen-off display mode corresponding to the screen-off display information is the ultra-low brightness monochromatic low-frame rate display mode; when the display time is in the non-sleep time or the user status is in the non-sleep state, it is determined that the screen-off display mode corresponding to the screen-off display information can be any mode other than the ultra-low brightness monochromatic low-frame rate display mode.

[0072] In one embodiment, when the user status is the no-person state and the display time is the non-sleep time, the projection device determines that the screen-off display mode corresponding to the information to be displayed can be the low brightness low-frame rate monochromatic display mode.

[0073] In one embodiment, when the user status is the someone state and the display time is the non-sleep time, the projection device determines that the screen-off display mode corresponding to the information to be displayed can be any one of the standard display mode, the high brightness monochromatic high-frame rate display mode, the high brightness monochromatic low-frame rate display mode, and the low brightness high-frame rate monochromatic display mode.

[0074] Step 206, display the information to be displayed through the target screen-off display mode.

[0075] Specifically, after the projection device determines the target screen-off display mode of the information to be displayed, further, it displays the information to be displayed according to the determined target screen-off display mode.

[0076] In this embodiment, when the projection device is in the screen-off state, it obtains the current information to be displayed of the user and the user status monitored in real time, where the information to be displayed includes the display time; and then determines the corresponding target screen-off display mode according to the display time, the user status, and the information to be displayed, so as to display the information to be displayed according to the target screen-off display mode. There are various screen-off display modes in this solution, and the power consumption of each screen-off display mode is much lower than that of the normal projection screen; and there are also some power consumption differences between each screen-off display mode. Further, when the projection device is in the screen-off state, the corresponding screen-off display mode is determined through the external environment and the display information, thereby reducing the power consumption of the projection device, and the projection device can be used all day long in the low power consumption state, increasing the interactivity between the projection device and the user, and increasing the user stickiness.

[0077] In one embodiment, obtaining the user's current information to be displayed includes: receiving real-time push information sent by one or more intelligent electronic devices; performing data processing on each real-time push information according to a preset user push rule to obtain the user's current information to be displayed.

[0078] The push information includes static content and dynamic content. For example, static content such as intelligent electronic device information, temperature, date, time, air index, weather, image, etc., and dynamic content such as video, lyrics, stock market information, scrolling text, dynamic pictures, etc.

[0079] Specifically, the projection device is network-connected to one or more intelligent electronic devices. When the projection device is in the screen-off state, it receives real-time push information sent by one or more intelligent electronic devices, and performs data processing on each received real-time push information through the push rule set by the user for the intelligent electronic device or the push rule set by the user for the projection device to obtain the user's current information to be displayed. For example, for an intelligent electronic device being an intelligent refrigerator, it receives the refrigerator temperature and refrigerator humidity transmitted by the intelligent refrigerator; the push rule set by the user for the intelligent refrigerator is to use the refrigerator temperature as the information to be displayed at the current moment, and thus determine the user's current information to be displayed.

[0080] In one embodiment, there are multiple screen-off display modes, and each screen-off display mode includes light source parameters and display parameters; the display parameters include the display unit refresh frequency and the display unit display parameters; determining the screen-off display mode corresponding to the information to be displayed as the target screen-off display mode according to the display time, user status, and information to be displayed includes: determining the information type of the information to be displayed; determining the target display unit refresh frequency corresponding to the information to be displayed according to the information type; determining the target light source parameters and target display unit display parameters corresponding to the information to be displayed according to the display time and user status; matching the corresponding screen-off display mode based on the target display unit refresh frequency, target light source parameters, and target display unit display parameters as the target screen-off display mode corresponding to the information to be displayed.

[0081] Among them, the light source parameters include the light source power and the light source driving frequency; the display parameters include the display unit refresh frequency and the display unit display parameters, where the display unit refresh frequency includes the display unit low refresh frequency and the display unit high refresh frequency. The target light source parameters are the light source parameters corresponding to the determined sub-light source, the target display unit display parameters are the determined display unit display parameters, and the target display unit refresh frequency is the determined display unit refresh frequency.

[0082] The information types include static types and dynamic types. The static type refers to the content of the information to be displayed as a static screen, such as the information of intelligent electronic devices, temperature, date, time, air index, weather, images and other static contents; the dynamic type refers to the content of the information to be displayed as a dynamic screen, such as videos, lyrics, stock market information, scrolling text, dynamic pictures, etc.

[0083] Specifically, the projection device determines the information type according to the information to be displayed obtained, and then determines the refresh frequency of the target display unit corresponding to the information to be displayed according to the determined information type; then determines the target light source parameters and the display parameters of the target display unit corresponding to the information to be displayed according to the display time and the user state; finally, matches the corresponding screen-off display mode based on the refresh frequency of the target display unit, the target light source parameters and the display parameters of the target display unit as the target screen-off display mode corresponding to the information to be displayed.

[0084] In one embodiment, the information types include static types and dynamic types; determining the refresh frequency of the target display unit corresponding to the information to be displayed according to the information type includes: when the information type of the information to be displayed is a static type, using the low refresh frequency of the display unit as the refresh frequency of the target display unit corresponding to the information to be displayed; when the information type of the information to be displayed is a dynamic type, using the high refresh frequency of the display unit as the refresh frequency of the target display unit corresponding to the information to be displayed.

[0085] For example, when the information type of the information to be displayed is a static type, the display time is non-sleep time, and the user state is an active state, the refresh frequency of the target display unit determined by the projection device is the high refresh frequency of the display unit. Then, according to the display time and the user state, the target light source power of the target light source parameters corresponding to the information to be displayed is 60%, the target light source driving frequency is 15HZ, the display refresh frequency of the target display unit is the high refresh frequency of the target display unit, and the display parameters of the target display unit are the high-transparency mode; finally, according to the determined target light source parameters and the display parameters of the target display unit and the 6 screen-off display modes corresponding to the projection device, the target screen-off display mode is determined to be the low-brightness high-refresh monochromatic display mode.

[0086] In one embodiment, the method further includes: obtaining the ambient illuminance monitored in real time; calling the user power consumption adjustment parameters stored locally; obtaining the display preference parameters of the user for the intelligent electronic device corresponding to the information to be displayed; adjusting the light source parameters and the display parameters of the target screen-off display mode according to the ambient illuminance, the user power consumption adjustment parameters and the display preference parameters; determining the adjusted screen-off display mode based on the adjusted light source parameters and the display parameters, and using the adjusted screen-off display mode as the target screen-off display mode.

[0087] Among them, the ambient illuminance can be obtained by real-time monitoring of sensors set in the environment, and the sensors can be light sensors. The user power consumption adjustment parameters include light source parameters and display parameters. The display preference parameters include the light source parameters, display parameters, and the screen-off display area for the projection device to display the information to be displayed transmitted by each intelligent electronic device.

[0088] In one embodiment, the display preference parameters can be set by the user for each intelligent electronic device when using the projection device; or after the user has used it for a period of time, the projection device learns the display preference parameters of the user for each intelligent electronic device according to the user's usage habits.

[0089] In one embodiment, obtain the projection device usage data of the user's screen-off state within a preset time, where the projection device usage data includes historical information to be displayed; determine the light source parameters, display parameters, and screen-off display area corresponding to each historical information to be displayed according to the projection device usage data; determine the display preference parameters of the intelligent electronic device corresponding to the historical information to be displayed according to the light source parameters, display parameters, and screen-off display area.

[0090] Specifically, based on the determined target screen-off display mode, the projection device obtains the real-time monitored ambient illuminance, calls the user power consumption adjustment parameters stored locally, further obtains the display preference parameters of the intelligent electronic device corresponding to the user's information to be displayed, and then adjusts the light source parameters and display parameters of the target screen-off display mode according to the obtained ambient illuminance, user power consumption adjustment parameters, and display preference parameters, and determines the adjusted screen-off display mode based on the adjusted light source parameters and display parameters, and takes the adjusted screen-off display mode as the target screen-off display mode.

[0091] In one embodiment, if the user power consumption adjustment parameters are not stored locally, after obtaining the real-time monitored ambient illuminance, obtain the display preference parameters of the intelligent electronic device corresponding to the user's information to be displayed; adjust the light source parameters and display parameters of the target screen-off display mode according to the ambient illuminance and display preference parameters; determine the adjusted screen-off display mode based on the adjusted light source parameters and display parameters, and take the adjusted screen-off display mode as the target screen-off display mode.

[0092] In one embodiment, when the display preference parameters of the intelligent electronic device corresponding to the information to be displayed are not obtained, adjust the light source parameters and display parameters of the target screen-off display mode according to the ambient illuminance and user power consumption adjustment parameters.
