Display device and method for rapidly displaying startup picture

Technical Field

Background

The laser television principle is to display images by using DLP technology. Taking a DMD chip as an example, the DMD chip is an imaging core component of a laser television, and millions of small mirrors are arranged, and each small mirror can be turned over in the positive and negative directions at a frequency of several tens of thousands times per second. Light rays are reflected by the small mirrors to directly form images on the screen, and due to the visual inertia of human eyes, three primary colors irradiated on the same pixel point in turn at a high speed are mixed and superposed to form colors.

In the current household laser television, because a laser display panel in the laser television has a startup time sequence requirement, when the laser television is started, a startup program of the laser television can sequentially start a startup mark, a startup animation and a picture after startup. However, since the starting time of the optical machine corresponding to the laser display panel is long, the optical machine is in a starting state while the starting program runs, so that if the optical machine is not completely started when the starting program runs to the starting identifier, the user cannot see the starting identifier in the laser television. In order to keep the interactive synchronization between the startup program and the laser display panel, a delay program is usually set in the startup program to delay the operation of the startup identifier, and after the optical engine of the laser display panel is started, the startup program is operated to sequentially display the startup identifier, the startup animation and the started picture.

In some embodiments, the display device 200 may receive the user's control through touch or gesture, etc., instead of receiving the instruction using the control device 300 or the control apparatus 100 described above.

In some embodiments, the display device 200 may also be controlled in a manner other than the control apparatus 100 and the control device 300, for example, the voice command control of the user may be directly received by a module configured inside the display device 200 and used for acquiring a voice command, or may be received by a voice control device provided outside the display device 200.

In some embodiments, the display device 200 is also in data communication with a server 400. The display device 200 may be allowed to be communicatively connected through a Local Area Network (LAN), a Wireless Local Area Network (WLAN), and other networks. The server 400 may provide various contents and interactions to the display apparatus 200. The server 400 may be a cluster or a plurality of clusters, and may include one or more types of servers.

As shown in fig. 2, the display apparatus 200 may include at least one of a tuner demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

In some embodiments, the controller 250 may include a processor, a video processor, an audio processor, a graphic processor, a RAM, a ROM, a first interface to an nth interface for input/output.

The display 260 may be a liquid crystal display, an OLED display, and a projection display, and may also be a projection device and a projection screen.

The communicator 220 is a component for communicating with an external device or a server according to various communication protocol types. For example: the communicator may include at least one of a Wifi module, a bluetooth module, a wired ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The display apparatus 200 may establish transmission and reception of control signals and data signals with the external control apparatus 100 or the server 400 through the communicator 220.

A user interface for receiving control signals for controlling the apparatus 100 (e.g., an infrared remote control, etc.).

The detector 230 is used to collect signals of the external environment or interaction with the outside. For example, detector 230 includes a light receiver, a sensor for collecting ambient light intensity; alternatively, the detector 230 includes an image collector, such as a camera, which may be used to collect external environment scenes, attributes of the user, or user interaction gestures, or the detector 230 includes a sound collector, such as a microphone, which is used to receive external sounds.

The external device interface 240 may include, but is not limited to, the following: high Definition Multimedia Interface (HDMI), analog or data high definition component input interface (component), composite video input interface (CVBS), USB input interface (USB), RGB port, and the like. The interface may be a composite input/output interface formed by the plurality of interfaces.

The tuner demodulator 210 receives a broadcast television signal through wired or wireless reception and demodulates an audio/video signal, such as an EPG data signal, from a plurality of wireless or wired broadcast television signals. In some embodiments, the controller 250 and the modem 210 may be located in different separate devices, that is, the modem 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

The controller 250 controls the operation of the display device and responds to the user's operation through various software control programs stored in the memory. The controller 250 controls the overall operation of the display apparatus 200. For example: in response to receiving a user command for selecting a UI object to be displayed on the display 260, the controller 250 may perform an operation related to the object selected by the user command.

In some embodiments, the controller 250 includes at least one of a Central Processing Unit (CPU), a video processor, an audio processor, a Graphic Processing Unit (GPU), a RAM Random Access Memory (RAM), a ROM (Read-Only Memory), a first interface to an nth interface for input/output, a communication Bus (Bus), and the like.

In this embodiment, a laser television is taken as an exemplary illustration of some embodiments of the present application, the laser television further includes an optical engine 290, and before the display 260 plays a corresponding picture, the optical engine 290 needs to project a content to be displayed onto the display 260.

In the booting process, while the internal hardware modules of the display device 200 are powered on and started one by one, a booting program is also required to be run, and the booting program is a control program related to booting, such as an initialization program, a booting image display program, and the like. The power-on process of the display device 200 can be further subdivided into a plurality of stages. As shown in fig. 3, after the display device 200 is powered on, the display 260 is powered on to light up the display 260. The kernel of the operating system and the user-level process are restarted to initialize the display device 200, and the initializing step further includes initializing the optical machine 290. After the display device 200 completes the initialization process of the system kernel and the user-level process, the display device 200 further controls the display 260 to start playing the boot animation by running the display program of the boot image. In the process of displaying the boot animation, the display device 200 may further run a generation and rendering program of a user interface such as a control homepage, or may further control the display 260 to display an initial display image for a user to perform an interactive operation after the boot animation is played according to a display program corresponding to the acquired default signal source.

The operating system kernel refers to a core part of an operating system of the display device 200, and is configured to run processes and provide inter-process communication. The operating system kernel may include related programs and hardware modules for managing memory, files, peripherals, and system resources. The Kernel of the operating system is adapted to the operating system specifically run by the display device 200, and taking Kernel as an example, the Kernel can implement Kernel functions of the operating system, such as scheduling and synchronization of events, communication (message transmission) between processes, memory management, and process management, after the Kernel starts running. In a Disk Operating System (DOS), an Operating System kernel is located between a Basic Input Output System (BIOS) and application software, and application commands can be transmitted to the BIOS through the Operating System kernel and then transmitted to related hardware.

The user-level process refers to a thread which is realized in a user program without kernel support, and the kernel switching of the user-level process is realized by controlling the kernel switching by a user-mode program without kernel interference. Taking the init process as an example, since the android system is operating on linux kernel, the starting process of the android system follows the starting process of the linux system. When the linux kernel is started, the first running user-level process is an init process. The init process is the first user-level process started by the kernel, and can start getty (for user login), realize the running level, process an isolated process and the like. As the daemon process, the init process runs all the time through the whole linux kernel, and the common basis of all other processes in the linux is the init process.

The operating system kernel and the user-level process are basic operating modules that the display device 200 can normally run, and therefore in the process of starting up and starting up, after each hardware module of the display device 200 needs to be powered on and run, the operating system kernel is started up first, and then the init and other user-level threads are called up, so that initialization of the display device 200 is achieved.

In some embodiments, to prompt the user that the current display device 200 has entered the boot program, the display device 200 may further display a specific boot screen through the display 260 after the hardware module is powered on, where the boot screen may include a static screen and a dynamic screen. Wherein the static image is typically displayed upon lighting up the display 260, such as a brand logo (logo) of the display device 200 or the display 260. The dynamic image needs to be displayed in the process of generating and rendering the user interface after the display device 200 completes initialization of the kernel of the operating system and the user-level process, for example, the dynamic image may be a boot animation, a boot advertisement, or the like.

Because the laser display panel of the laser television has a startup time sequence requirement, when the laser television is started, the startup program of the laser television sequentially obtains the startup identifier, the startup animation and the initial display picture after startup, and sends the startup identification, the startup animation and the initial display picture to the optical machine 290 to project to the display 260 for the user to watch. However, since the startup time of the optical engine 290 is long, the optical engine 290 is in a startup state while the startup program is running, and the corresponding projection operation cannot be performed. However, if the optical engine 290 is started, the startup program is normally running, and the optical engine 290 projects according to the startup program, the projected startup mark or startup animation will be missed, and the user cannot see the complete startup picture.

In order to solve the above problem, in some embodiments, a delay program is set in the boot program, and before the optical engine 290 is completely started, the delay program is run to delay the running of the boot identifier and the subsequent boot animation until the boot state of the optical engine 290 is detected to be completely started, and then the corresponding boot identifier, boot animation and initial display frame are projected to the display 260 through the optical engine 290. However, although the above process enables the user to view a complete startup picture, setting the delay program may prolong the overall startup time of the laser television, increase the waiting time of the user, and cause poor user experience.

To enhance the experience of the user, some embodiments of the present application provide a display device 200, which includes a display 260, an optical engine 290, and a controller 250. The display 260 receives the playing content projected by the optical engine 290, and displays the playing content on the display device 200. After receiving the power-on command input by the user, the controller 250 initializes the optical transceiver 290 and executes the power-on program in the background. As shown in fig. 4, fig. 4 is a schematic diagram illustrating the optical engine 290 projecting the boot identifier to the display 260. The optical engine 290 projects a power-on identifier to the display 260 during the initialization operation. At this time, the display 260 continuously displays the power-on flag during the initialization of the optical transmitter 290. During this period, the controller 250 continuously detects the boot state of the optical machine 290 and searches for boot resources according to the boot program. When the booting resource is in the state to be projected and the controller 250 detects that the starting state of the optical engine 290 is the ready state, the optical engine 290 is controlled to cancel the originally displayed booting identifier and sequentially project the booting resource to the display 260. The starting-up resources comprise starting-up animation and an initial display picture.

In some embodiments of the present application, the optical engine 290 sequentially projects a startup animation and an initial display image to the display 260 according to a startup program, where the initial display image may be an image corresponding to a default signal source or a video source accessed by the external device interface 240 on the display apparatus 200. For example, the video playing source of the mobile terminal, such as a mobile phone and a notebook computer, accessed through the external device interface 240 may also be a resource, such as a picture and a video, in a mobile storage tool, such as a usb disk and a mobile disk.

Because the optical engine 290 has different signals, the starting time of the optical engine 290 with different models is different, and the time of the started delay program is different. For example, the optical engine 290 of 100L9F-PRO model has 9s of start time, and the optical engine 290 of three-color laser model has 5s of start time. Therefore, in some scenarios, the start-up state of the optical engine can be determined by querying the start-up duration of the optical engine 290. In some embodiments of the present application, the controller 250 may also query the start time of the optical engine 290, which is generally the time between the start of the initialization operation of the optical engine 290 and the ready state of the optical engine 290.

After the controller 250 acquires the power-on command input by the user, the optical engine 290 is initialized and the power-on program is executed in the background. And recording the starting-up time length while running the starting-up program, wherein the starting-up time length is the accumulated time length from the running moment of the starting-up program to the current moment.

As shown in fig. 5, the controller 250 records the power-on duration after receiving the power-on command input by the user. When the controller 250 finds the boot resources according to the boot program, it determines whether the boot time length at this time reaches the boot time length. If the booting time length reaches the starting time length, it indicates that the starting state of the optical engine 290 is in the ready state at this time, and the booting resources can be projected to the display 260. If the starting time does not reach the starting time, it indicates that the starting state of the optical engine 290 is in the non-ready state at this time, and the starting resources cannot be projected. If the booting program continues to run, the booting resources continue to run in the background, and the projected booting resources are not completely played until the optical engine 290 is ready to start. Therefore, the time difference between the boot time and the start time needs to be calculated, and the delay program is run according to the time difference, so that it is ensured that the boot resource is in a non-running (non-playing) state when the optical transmitter 290 is ready.

By taking the optical engine 290 of model number 100L9F-PRO as an exemplary description of some embodiments of the present application, the starting time of the optical engine 290 is 9s. When the startup duration is less than 9s, it indicates that the optical engine 290 has not been started yet, and has no capability of playing other contents except the projected startup identifier. When the startup duration reaches or exceeds the startup duration, it indicates that the optical engine 290 has been started up and is in a ready state, and at this time, the controller 250 controls the optical engine 290 to sequentially project the startup animation and the image corresponding to the default signal source to the display 260, thereby completing the startup image display.

Referring to FIG. 6, optical engine 290 of FIG. 6 is a three color laser model optical engine 290. In the embodiment shown in fig. 6, the controller 250 finds the startup resource within 5s after running the startup program, and the start-up duration of the optical engine 290 with the three-color laser model is also 5s, which means that after the controller 250 finds the startup resource, the optical engine 290 is just started and is in the ready state. Then, the controller 250 sends the startup resource to the optical engine 290, and after receiving the startup resource, the optical engine 290 sequentially projects the startup animation in the startup resource and the picture corresponding to the default signal source to the display 260, so as to complete the display of the complete startup animation.

Before the boot time length reaches the start time length, the controller 250 may further obtain a search result of the boot resource. When the search result is found, which indicates that the boot-up duration reaches the start-up duration, the controller 250 already finds the boot-up resources according to the boot-up procedure, and then starts to sequentially play the boot-up animation and display the initial display image in the background according to the boot-up procedure. At this time, the startup duration does not reach the startup duration, the startup state of the optical engine 290 is not ready, and the startup animation cannot be played. When the optical engine 290 is in the ready state, only a portion of the boot animation content may be displayed, so that the user cannot completely see the boot animation. In some embodiments of the present application, when the search result of obtaining the boot-up resource is found, the controller 250 may further calculate a time difference between the start-up time and the boot-up time, run the delay program according to the time difference, so that the boot-up animation and the picture corresponding to the default signal source are delayed to run in the background, and project the boot-up animation and the picture corresponding to the default signal source to the display 260 by the delay optical transceiver 290.

In some embodiments of the present application, the starting duration is less than the starting duration, and before the starting state of the optical engine 290 is ready, the controller 250 finds the corresponding starting resource according to the starting program, so the controller 250 calculates a difference between the starting duration and the starting duration to obtain a duration difference between the time when the starting resource is found and the time when the starting state of the optical engine 290 is ready, where the duration difference is the time for running the delay program. After the controller 250 runs the delay program according to the time difference, the delay program is just finished when the optical machine 290 is in the ready state. The controller 250 controls the optical engine 290 to sequentially project the startup animation and the image corresponding to the default signal source to the display 260, so as to display a complete startup image on the display 260.

By taking the optical engine 290 of model number 100L9F-PRO as an exemplary description of some embodiments of the present application, the starting time of the optical engine 290 is 9s. The controller 250 finds the boot resources after running the boot program in the background for 5s. At this time, the controller 250 obtains the found result, but the optical engine 290 has not completed the activation. At this time, the controller 250 calculates a time difference between the start-up time period and the power-on time period of the optical computer 290, that is, a time difference 4s between the start-up time period 9s and the power-on time period 5s of the optical computer 290. And the delay program of 4s is run to keep the startup resource in the non-projected state, after 4s, the optical engine 290 finishes starting, at this moment, the controller 250 stops running the delay program and sends the startup resource to the optical engine 290, and after receiving the startup resource, the optical engine 290 projects the startup animation in the startup resource and the picture corresponding to the default signal source to the display 260 in sequence to finish the complete startup animation display.

In some embodiments of the present application, the optical engine 290 may generate a shot stuck phenomenon immediately after the initialization operation is completed. In order to prevent the light engine 290 from being stuck when it is just started and the light engine 290 sequentially projects the boot animation to the display 260, the controller 250 may further extend the time for running the delay program based on the time difference.

After the optical engine 290 projects the startup resource to the display 260, the display 260 displays the picture corresponding to the startup resource, and the display device 200 also plays the audio source of the startup resource. In some embodiments of the present application, the display device 200 further includes an audio output interface configured to output a sound signal. Before the startup duration reaches the startup duration, the controller 250 may further control the audio output interface 270 to suspend outputting the sound signal, so as to start the mute logic, and prevent the audio source corresponding to the startup resource from being suddenly played to impact the audio output interface 270 when the optical engine 290 is not started, thereby prolonging the service life of the audio output interface 270. Meanwhile, the optical engine 290 can be prevented from suddenly making a sound or a noise when not started, and thus, the watching user is frightened.

When the startup duration reaches or exceeds the startup duration, it indicates that the optical engine 290 is already in the ready state, and can project the startup resources to the display 260. At this time, the controller 250 controls the audio output interface 270 to turn on the output sound signal to turn off the mute logic, and the controller 250 may also simultaneously control the optical machine 290 to project the power-on resource to the display 260 to synchronously play the audio source corresponding to the power-on animation, so as to prevent the problem of audio-video asynchronization of the power-on animation, and improve the experience of the user. As shown in fig. 8, after receiving the power-on command input by the user, the controller 250 searches for the power-on resource and suspends the audio output interface 270 from outputting the audio signal. After the controller 250 finds the power-on resource, it detects whether the start-up state of the optical engine 290 is the ready state. If the light engine 290 is in the ready state, the controller 250 controls the audio output interface 270 to start outputting the audio signal and controls the light engine 290 to project the power-on animation to the display 260. If the light engine 290 is not ready, it is unable to project the boot resources to the display 260. The audio output interface 270 continues to pause outputting the audio signal, and the pause duration is the duration from the time the controller 250 finds the starting-up resource to the time the starting state of the optical engine 290 is started.

In some embodiments of the present application, the duration of the startup of the optical engine 290 is 9s, and the controller 250 finds the startup resource after running the background startup program for 5s. At this time, the controller 250 detects that the light engine 290 is in the ready state. In order to prevent the audio source corresponding to the power-on resource from being suddenly played and causing impact on the audio output interface 270, the controller 250 controls the audio output interface 270 to suspend outputting the audio signal, so that the audio source corresponding to the power-on resource cannot be played through the audio output interface 270, and the start of the mute logic is completed. After 4s, the startup duration reaches the startup duration of the optical engine 290, and at this time, the controller 250 detects that the startup status of the optical engine 290 is the ready status, and at this time, the optical engine 290 may project the startup resource to the display 260. When the display 260 displays the corresponding picture, the audio output interface 270 of the display device 200 is further required to play the audio source corresponding to the power-on resource to achieve the effect of sound-picture synchronization, at this time, the controller 250 switches on the audio output interface 270, turns on the output sound signal to turn off the mute logic, and at the same time, the audio output interface 270 sends the audio source corresponding to the power-on resource to the audio playing device in a sound signal manner to play the audio source. Wherein, the audio playing device can include: the display device 200 can be a sound box provided by itself, or an external smart sound box, and the like.

As shown in fig. 9, when the controller 250 finds the power-on resource, if the power-on duration is greater than the start duration, the on state of the optical engine 290 is the ready state, and the controller 250 turns off the mute logic to output the sound signal through the audio output interface 270. If the startup duration is less than the startup duration, it indicates that the startup state of the optical engine 290 is an idle state, and at this time, the mute logic needs to be extended until the startup duration reaches the startup duration, and the controller 250 turns off the mute logic again.

In some embodiments of the present application, the booting duration exceeds the starting duration, which indicates that the controller 250 has not found the booting resource after the optical engine 290 is in the ready state. Therefore, the controller 250 cannot control the optical engine 290 to project the power-on resource to the display 260. At this time, the controller 250 may also calculate the time that the power-on duration exceeds the start-up duration, and continue to pause the output of the audio signal to prolong the operation of the mute logic. The controller 250 may also continuously obtain the results of the lookup of the boot resources during the extended run mute logic. When the search result is found, the controller 250 controls the audio output interface to turn on to output the audio signal to turn off the mute logic, and controls the optical engine 290 to project the power-on resource to the display 260, so as to achieve the sound-picture synchronization effect of displaying a complete power-on picture by the display device 200.

In some embodiments of the present application, when the controller 250 runs the boot program, and after the controller 250 finds the boot resource, the controller 250 may further turn on the physical signal source of the boot program in the background. The physical signal source is used for the controller 250 to transmit the booting resources searched according to the booting program to the optical engine 290. When the controller 250 detects that the light engine starting state is the ready state, the starting animation and the initial display frame are sequentially transmitted to the light engine 290 through the physical signal source.

In some embodiments of the present application, the physical signal source may also be used to transmit target video as well as target audio. In the initial display frame, a list of asset programs or a live channel is usually included, where the list of asset programs includes at least one asset program, and the live channel includes at least one channel. As shown in fig. 10, the initial display frame is a movie list, the movie list includes a plurality of movies, and the controller 250 may search for a playing resource of a corresponding movie according to a selection instruction issued by a user, and project the playing resource to the display 260 through the optical engine 290 for the user to watch.

For example, when a user selects any one of the media asset programs by using the control device 100, the controller 250 may further obtain a playing resource corresponding to the media asset program, and send the playing resource to the optical engine 290 through the physical signal source, after the optical engine 290 receives the playing resource, the playing resource is projected onto the display 260, and the user may view the corresponding media asset program on the display 260. If the user selects a live channel by using the control device 100, the controller 250 may further obtain a live broadcast source of the corresponding channel through a server corresponding to the lan, and send the content of the live broadcast to the optical engine 290 through a physical signal source. After receiving the live broadcast content, the optical engine 290 projects the corresponding live broadcast content to the display 260.

In some embodiments of the present application, the boot resources include boot animation and a picture corresponding to the default signal source, and the display device 200 generally plays the boot animation first during the boot process, and then displays the initial display picture after the boot animation is played. Therefore, as shown in fig. 11, the controller 250 may also search the frames corresponding to the power-on resource and the default signal source in sequence. Within 5s of starting the optical engine 290, the controller 250 searches for the resource corresponding to the boot animation according to the boot program, and sends the resource corresponding to the boot animation to the optical engine 290 after finding the boot animation, and the optical engine 290 projects the boot animation of 10s to the display 260 after receiving the resource corresponding to the boot animation. During the time that the light engine 290 projects the power-on animation, the controller 250 may also look up the corresponding picture of the default signal source. If the controller 250 finds the resources of the picture corresponding to the default signal source before the optical engine 290 finishes projecting the startup animation, the controller 250 may send the resources of the picture corresponding to the default signal source to the optical engine 290 during the process that the startup animation is being played, and then after the startup animation is finished, the controller 250 controls the optical engine 290 to directly project the picture corresponding to the default signal source to the display 260, so that the time for the controller 250 to find the startup resources according to the startup program is saved, a user can quickly see the startup picture, and the experience of the user is improved.

In some embodiments of the present application, when the controller 250 sends the resource of the picture corresponding to the default signal source to the optical machine 290, the controller may also send a to-be-projected instruction to the optical machine 290 synchronously, where the to-be-projected instruction is used to instruct the optical machine 290 to project the picture corresponding to the default signal source to the display 260. After receiving the resources of the picture corresponding to the default signal source and the to-be-projected instruction, the optical engine 290 generates the to-be-projected task according to the resources of the picture corresponding to the default signal source and the to-be-projected instruction. At this time, the current projection task of the optical engine 290 is to project the startup animation, and after the current projection task is finished, it indicates that the startup animation has been played at the display 260. The optical engine 290 then performs a projection task to project a picture corresponding to the default signal source to the display 260.

Referring to fig. 12, if the user does not want to view the power-on animation, the controller 250 may further obtain a first skip instruction input by the user, and in response to the first skip instruction, control the optical engine 290 to cancel the projection of the power-on identifier, skip the projection of the power-on animation to the display 260, and directly project the picture corresponding to the default signal source to the display 260. The first skip instruction may be an instruction issued by the user through any key on the control apparatus 100, or may be a voice instruction issued by the user.

For example, the user speaks a "skip boot animation" voice command before the optical engine 290 projects the boot animation to the display 260, and the display device 200 may recognize the voice command uttered by the user and generate a first skip command according to the recognized content.

The first jump instruction may also be an action instruction issued by the user, and the display device 200 may also capture the action instruction of the user by turning on a camera function carried by the display device, where the action instruction may be an instruction that can be triggered by an action preset by the user. For example, when the user sets in advance that a hand-waving motion is performed, the current screen is skipped. Before the display 260 plays the boot animation, when the display device 200 starts the camera function to capture the motion of waving the hand of the user upwards, the controller 250 generates a first jump instruction according to the captured result, and controls the optical engine 290 to jump over projecting the boot animation to the display 260 and directly project the picture corresponding to the default signal source to the display 260.

However, when the controller 250 searches for the startup animation and the picture corresponding to the default signal source in sequence according to the startup program, the startup animation is being played on the display 260 at this time because the picture corresponding to the default signal source is searched during the period when the optical engine 290 projects the startup animation to the display 260. If the controller 250 responds to the first skip instruction at this time, the optical engine 290 skips playing the boot animation if the picture corresponding to the default signal source is not found, which may cause a neutral picture to appear on the display 260 and the user cannot view the effective picture.

In contrast, in some embodiments of the present application, the controller 250 obtains the picture corresponding to the default signal source according to the boot program when the optical engine 290 projects the boot animation to the display 260 after finding the resource of the boot animation according to the boot program. As shown in fig. 13, when the controller 250 acquires the picture corresponding to the default signal source, a second jump instruction input by the user is acquired, where the second jump instruction is used to instruct the optical engine 290 to skip projecting the startup animation that has not been played after the controller 250 acquires the picture corresponding to the default signal source. Then, the controller 250 controls the optical engine 290 to project the image corresponding to the default signal source to the display 260, so as to complete the display of the startup image. The generation manner of the second skip instruction is the same as that of the first skip instruction, and details of some embodiments of the present application are not described herein.

In some embodiments of the present application, the controller 250 may also obtain the startup animation and the image corresponding to the default signal source at the same time, and when the controller 250 detects that the startup state of the optical engine 290 is ready, the optical engine 290 will project the startup animation to the display 260 for playing. During playback, because the controller 250 has already captured the picture corresponding to the default signal source, the controller 250 can also capture a second skip instruction input by the user at any point during playback of the power-on animation on the display 260. The controller 250 controls the optical engine 290 to skip the projection of the unplayed boot animation in response to the second skip instruction, and to change the projection to the picture corresponding to the default signal source. The input time point of the second jump command may be any time point between the optical engine 290 starting to project the start-up animation to the display 260 and the optical engine 290 finishing to project the start-up animation.

In some embodiments of the present application, when the controller 250 runs the boot program in the background, the boot program and the kernel program are also run in the background, the boot program is started according to the boot program, and the boot program is executed according to the kernel program. In the background process of starting the display device 200, the controller 250 runs a boot loader, and the boot loader is used to start a boot program. After the boot program is started, the kernel program is started at the same time, and the controller 250 runs the boot program through the kernel program, where the boot program further includes a search link of the boot resource, or a running program of the boot resource.

In some display devices 200, the user may also determine the style of the boot animation according to his or her preference. In some embodiments of the present application, the boot program further includes a resource search link of at least one boot animation. The controller 250 may further obtain the type of the boot animation preset by the user, and match the search connection of the corresponding boot animation according to the style, so as to search for the resources of the boot animation corresponding to the style. The above embodiments may also be applied to acquiring resources of a picture corresponding to a default signal source.

When the user watches the playing content displayed by the display device 200, if power failure occurs, or the user accidentally touches the power interface of the display device 200, the display device 200 is powered off, and the picture is interrupted. In some embodiments of the present application, the controller 250 may further obtain, according to the power-on program, resources of a history picture displayed before the last shutdown of the display device 200, and when the controller 250 detects that the start state of the optical engine 290 is the ready state, search for power-on animation resources and history picture resources. When the optical engine 290 finishes projecting the boot animation to the display 260, the history picture is projected next to solve the problem that the user cannot continuously watch the playing content when the display device 200 is powered off.

Referring to fig. 14, some embodiments of the present application further provide a method for quickly displaying a startup picture, which is applied to a display device 200, where the display device at least includes a display 260, an optical engine 290, and a controller 250, and the method includes:

s100: acquiring a starting-up instruction input by a user;

s200: responding to the starting instruction, executing initialization operation on the optical machine, and running a starting program in a background;

s300: controlling the optical machine to project a starting-up identifier to the display;

s400: during the period that the optical machine projects the starting-up identifier, detecting the starting-up state of the optical machine, and searching starting-up resources according to the starting-up program, wherein the starting-up resources comprise starting-up animation and an initial display picture;

s500: and when the starting state of the light machine is detected to be a ready state, controlling the light machine to project the starting animation and the initial display picture to the display in sequence.

According to the above scheme, the display device and the method for rapidly displaying the startup picture provided by some embodiments of the present application can execute the initialization operation on the optical transceiver after receiving the startup instruction input by the user, and run the startup program in the background. And in the process of searching the starting-up animation and the initial display picture according to the starting-up program, controlling the optical machine to project a starting-up mark to the display in advance, and detecting the starting state of the optical machine in the period. After the startup animation and the initial display picture are searched according to the startup program, if the startup state of the optical machine is the ready state, the optical machine projects the startup animation to the display, and when the startup animation is played, the initial display picture is projected. The display displays corresponding playing contents according to the projection of the optical machine in sequence. According to the method and the device, the starting-up identification is projected to the display in advance during the period of searching the starting-up resources and starting the optical machine according to the starting-up program, and after the starting-up resources are ready and the optical machine is started, the corresponding display picture is projected for the display to display. The user can see the picture displayed on the display without waiting for a long time, so that the time for the user to wait for starting up is reduced, and the experience of the user is improved.
