[0002] The projection device is provided with a light modulation component, and the light modulation can be used to display images. The projection device may include a laser projection device such as a laser TV.

[0003] At present, when a frame of image is displayed through a light modulation component, the frame of image needs to be loaded first, and after loading is completed, the light modulation component is controlled to display the frame of image. The time required to display a frame of image is related to the display frame rate of the projection device. For example, when the display frame rate of the projection device is 60Hz, that is, 60 frames of image are displayed per second, the display time of each frame of image is 1 / 60 second.

[0004] However, when the projection device is in a scenario with high requirements for image display delay, such as a gaming scenario, the display time of each frame of the image in the prior art is relatively long, that is, the image refresh demonstration is relatively long, and there may be screen freezes, resulting in a poor user experience. Summary of the invention

[0046] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0047] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0048] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0049] The frame rate adjustment method provided in the embodiment of the present application can be applied to electronic devices with display functions.

[0050] The projection device provided in the embodiments of the present application may have various implementation forms, for example, it may be a laser projection device, a monitor, etc.

[0051] In order to better understand the embodiments of the present application, the structure of the laser projection device in the embodiments of the present application is introduced below by taking the projection device as a laser projection device as an example:

[0052] Figure 1 A schematic diagram of the architecture of a laser projection device provided in an embodiment of the present application.

[0053] like Figure 1As shown, the laser projection device may include: a display panel 001, a power panel 002, and a TV panel 003. Among them, the power panel 02 is connected to the display panel 001 and the TV panel 003 respectively, and can be used to power various devices or partial modules on the display panel 001 and the TV panel 003. At the same time, it can also power other functional modules in the laser projection device, such as the human eye protection module, the fan, the WIFI module, etc., to ensure the normal power supply of various parts of the laser projection device. In some specific implementations, a laser driving circuit may also be provided on the power panel 002. Alternatively, the laser driving circuit may also be provided independently of the power panel 002.

[0054] TV board 003 is mainly used for decoding external audio and video signals.

[0055] The TV panel 003 is provided with a system on chip (SoC), which can decode data in different data formats into a normalized format, and transmit the data in the normalized format to the display panel 001 through, for example, a connector.

[0056] The video image signal output by the TV panel 003 is transmitted to the display panel 001 .

[0057] The display panel 001 may be provided with a Field Programmable Gate Array (FPGA) and an algorithm processing module FPGA, which are used to process the input video image signal, such as performing MEMC frequency multiplication processing or image correction to realize image enhancement functions. The projection display control processing unit 010 is connected to the algorithm processing module FPGA to receive the processed video image processing signal data as the image data to be displayed. It should be noted that FPGA usually exists as an enhancement function module. In some low-cost solutions, this module part may not be provided, and the projection display control processing unit 010 receives the video image display signal output by the TV panel 003.

[0058] The projection display control processing unit 010 mainly includes a digital light processing chip (Digital Light Processing, DLP), and may also include a driving chip.

[0059] In the DLP control architecture, the DMD chip is the core light modulation device. The light source part needs to cooperate with the working timing of the DLP chip and the DMD chip. Specifically, the DLP chip outputs an image enable signal, which can also be called a primary color light enable signal, usually expressed as X_EN, where X is the abbreviation of different primary color lights, and also outputs a brightness adjustment signal, referred to as a PWM signal. Along with the DMD chip's timing modulation process of different primary color image components, the light source part needs to synchronously output the primary color light beams of the corresponding colors. That is, the DLP chip outputs a primary color light enable signal to notify the laser light source to enable the lighting of a laser component of a certain color, and outputs a PWM signal to notify a certain laser component in the laser light source to light up at what brightness.

[0060] In the figure, the laser assembly 040 can be used to provide a light source illumination beam, which is transmitted to the rear light modulation device and projection lens ( Figure 1 The laser assembly 040 may include a laser assembly of at least one color, such as a blue laser assembly, or a two-color laser assembly, such as a blue laser assembly and a red laser assembly, or a three-color laser light source, including laser assemblies of three colors, red R, green G, and blue B, for providing a three-color laser illumination beam.

[0061] Based on the above Figure 1 The structure of the laser projection device is shown below, and the DLP display system is described in detail. Figure 2 A structural schematic diagram of a DLP system provided in an embodiment of the present application.

[0062] like Figure 2 As shown, the DLP system may include a multimedia module, a light modulation controller, a light modulation device, a lens, and a light source assembly.

[0063] The multimedia module can be used to send an image signal of an image to be displayed to the light modulation controller. The image signal may include a television signal, a computer signal, etc., which is not limited in the embodiments of the present application.

[0064] The light modulation controller can be used to receive the image signal of the image to be displayed transmitted by the multimedia module, and according to the image signal, control the micromirrors on the light modulation device to flip according to a certain timing, and control the light source assembly to emit a light beam.

[0065] In a possible implementation, the optical modulation controller may be a DMD controller, which is not limited in the embodiment of the present application.

[0066] The light modulation device may include thousands of regularly arranged and mutually hinged micro-reflective lenses (referred to as micro-mirrors in this application) for reflecting incident light beams to form images.

[0067] The light source component can be used to emit a light beam, and may include emitting laser, LED light or other components that can form visible light, which is not limited in the embodiments of the present application.

[0068] The lens can be used to receive the light beam reflected by the light modulator and project the light beam into an image after shaping. For example, the lens can project the light beam reflected by the light modulator onto a projection screen.

[0069] like Figure 2 As shown, when the DLP system is imaging, the multimedia module can transmit the image signal of the image to be displayed to the light modulation controller, and the light modulation controller can generate a light source timing control signal and a modulation control signal according to the image signal. The light modulation controller can control the light source assembly to emit a light beam through the light source timing control signal, and the light beam emitted by the light source assembly can be irradiated onto the micromirror of the light modulation device. The light modulation controller can also control the rotation of the micromirror in the light modulation device through the modulation control signal to modulate the incident light beam. The light beam modulated by the light modulation device is incident on the lens, and the incident light beam is projected and imaged through the lens.

[0070] Exemplarily, when the laser assembly emits light beams of multiple colors, the light modulation controller can control the display time of the light beams of each color according to the display time of each color through the light source timing control signal.

[0071] Exemplarily, there are tens of thousands of tiny reflectors on the surface of the optical modulator, and the size of each micro-reflector is only one-fifth of a hair. According to the state in which each lens can reflect light to the lens (rotate +12 degrees) toward the light source, and the state in which the backlight cannot be reflected to the lens (rotate -12 degrees), they are marked as "on" and "off" respectively. The micro-reflector lens can form about 1024 levels of grayscale (gray scale) between rapid rotations. Therefore, when the optical modulation controller controls the rotation of the micro-mirrors in the optical modulator by modulating the control signal, the angle and duration of the flipping of each micro-mirror in the optical modulator can be controlled, which is not limited in the embodiments of the present application.

[0072] In this way, the light modulation controller controls the light modulation device to flip according to the gray scale of the color and the set timing through the modulation control signal.

[0073] Since the micromirror in the optical modulator is very light and the torsion arm beam of the micromirror is very thin (about 0.05-0.1um), the moment of inertia is very small, and the response time of the optical modulator is very fast, from the fully open state to the fully closed state is about 10us. Therefore, the optical modulation component can complete the refresh of the micromirror within the specified time.

[0074] At present, the light modulation controller controls the light modulation device in a full-frame refresh manner to perform refresh control on the micromirrors in the light modulation device.

[0075] Taking the projection device as a laser projection device, in which the laser in the laser projection device emits three primary color beams of R, G, and B in a time-sharing manner as an example, the process of controlling the light modulation component to display one frame of an image is described, such as Figure 3 As shown, Figure 3 A schematic diagram of an existing process for completing the display of one frame of image provided in an embodiment of the present application.

[0076] like Figure 3 As shown, when displaying 1 frame of image, the light modulation component can refresh the B component under the control of the modulation control signal. When the B component is refreshed, the light source component can be controlled to emit a light beam of R color. When the light beam is switched to the R color, the R component can be refreshed. When the R component is refreshed, the light source component can be controlled to emit a light beam of G color. When the light beam is switched to the G color, the G component can be refreshed to complete the display of 1 frame of image.

[0077] There are two implementations of displaying image frames by light modulation components:

[0078] In one implementation, Figure 4 A schematic diagram of an existing process of displaying image frames through a light modulation component is provided in an embodiment of the present application.

[0079] like Figure 4 As shown, the light modulation controller can obtain the image signal of one frame of image to be displayed in the multimedia module each time, and cache the image signal of the frame image. When the image signal of the entire frame image is cached, the micromirror in the light modulation device is controlled to flip to display the cached image.

[0080] Correspondingly, taking the display frequency of the projection device as 60 Hz as an example, the timing of caching image frames and displaying image frames can be seen in Figure 5 As shown, Figure 5 A schematic diagram of the timing of displaying an image by an existing light modulation component provided in an embodiment of the present application.

[0081] When the display frequency of the projection device is 60Hz, the time to cache a frame of image and display a frame of image is 16.7ms. Figure 5As shown, in the time period of 0-16.7ms, the light modulation controller caches image frame 2, and the light modulation device is in a waiting state. The light modulation controller caches image frame 2 at 16.7ms. In the time period of 16.7ms-33.4ms, the light modulation controller is in a waiting state, and the light modulation device can display image frame 2 under the control of the control signal. The light modulation device completes the display of image frame 2 at 33.4ms. At this time, the laser projection device can display image frame 2. In the time period of 33.4ms-50.1ms, the light modulation controller caches image frame 3, and the light modulation device is in a waiting state. The light modulation controller caches image frame 3 at 50.1ms. In the time period of 50.1ms-66.8ms, the light modulation controller is in a waiting state, and the light modulation device can display image frame 3 under the control of the control signal. The light modulation device completes the display of image frame 3 at 66.8ms. At this time, the laser projection device can display image frame 3.

[0082] It is understandable that in this implementation, the optical modulation component completes the above Figure 3 The process shown displays a frame of image.

[0083] However, in this implementation, the projection device refreshes a frame of image every 33.4ms. When in scenarios with high display latency requirements such as games, the latency in this implementation is high, and there may be screen switching jams, resulting in a poor user experience.

[0084] In another implementation, the light modulation component can cache image frames and display image frames at the same time, see Figure 6 As shown, Figure 6 A schematic diagram of another existing process of displaying image frames through a light modulation component provided in an embodiment of the present application.

[0085] like Figure 6 As shown, the light modulation controller can cache 2 frames of images. The light modulation controller can obtain an image signal of a frame of image to be displayed in the multimedia module, and cache the image signal of the frame of image. After the image signal of the entire frame of image is cached, the micromirror in the light modulation device is controlled to flip to display the cached image. Moreover, when the image signal of the entire frame of image is cached, the light modulation controller can obtain the image signal of the next frame of image to be displayed in the multimedia module while controlling the light modulation device.

[0086] Correspondingly, taking the display frequency of the projection device as 60 Hz as an example, the timing of caching image frames and displaying image frames can be seen in Figure 7 As shown, Figure 7 A schematic diagram of the timing of displaying an image by another existing light modulation component provided in an embodiment of the present application.

[0087] When the display frequency of the projection device is 60Hz, the time to cache a frame of image and display a frame of image is 16.7ms. Figure 7 As shown, in the time period of 0-16.7ms, the light modulation controller caches image frame 2, and the light modulator can display image frame 1 under the control of the control signal. The light modulation controller caches image frame 2 at 16.7ms, and the light modulation device completes the display of image frame 1, and the laser projection device can display image frame 1. Among them, image frame 1 is the image frame that has been cached before.

[0088] In the time period of 16.7ms-33.4ms, the light modulation controller caches image frame 3, and the light modulation device can display image frame 2 under the control of the control signal. The light modulation controller finishes caching image frame 3 at 33.4ms, and the light modulation device completes displaying image frame 2 at 33.4ms. At this time, the laser projection device can display image frame 2. In the time period of 33.4ms-50.1ms, the light modulation controller caches image frame 4, and the light modulation device can display image frame 3 under the control of the control signal. The light modulation controller finishes caching image frame 4 at 50.1ms, and the light modulation device completes displaying image frame 3 at 50.1ms. At this time, the laser projection device can display image frame 3.

[0089] It is understandable that in this implementation, the optical modulation component completes the above Figure 3 The process shown displays a frame of image.

[0090] However, in this implementation, the projection device refreshes a frame of image every 16.7ms. When in scenarios with high display latency requirements such as games, the latency in this implementation is still high, and there may still be screen switching jams, resulting in a poor user experience.

[0091] Based on this, the embodiment of the present application provides a display method, when displaying a frame of image through a light modulation component, the frame of image can be divided into multiple parts, and the light modulation component is controlled to display the image in turn according to the image signal of each image. In this way, the projection device can display a part of a new frame of image in a shorter time, so that the user can see the change of the image in a shorter time, improve the situation of screen freeze caused by the long delay in displaying a complete frame of image, and improve the user experience.

[0092] In conjunction with the structure of the projection device described in the above drawings, the display method provided in the embodiment of the present application is described, which can be seen in Figure 8 As shown, Figure 8 A flowchart of a display method provided in an embodiment of the present application.

[0093] like Figure 8As shown, the display method may include the following steps:

[0094] S801: Acquire a signal of an image to be displayed, where the signal of the image to be displayed includes a plurality of image signals.

[0095] Acquiring a plurality of image signals may be performed by the light modulation controller in the above-mentioned embodiment.

[0096] Exemplarily, after the light modulation controller acquires the signal of the image to be displayed, the signal of the image to be displayed may be divided into a plurality of image signals, so as to display an image for each image signal.

[0097] S802: Generate a target control signal corresponding to the target image signal according to the target image signal among the multiple image signals.

[0098] The target image signal may be any one of the multiple image signals, or may be determined according to the corresponding position of the image signal in the image to be displayed, which is not limited in the embodiment of the present application.

[0099] For example, if the image to be displayed is a 10×10 image, the image to be displayed is divided into 10 parts, each of which corresponds to a row of the head portrait to be displayed, that is, 10 image signals can be obtained. Then, the 10 image signals can be processed in order from top to bottom. The target image signal can be the image signal corresponding to the first row.

[0100] The target control signal may be a signal for controlling an optical modulation device, which is not limited in the embodiments of the present application.

[0101] S803: Use the target control signal to control the light modulation device in the projection device to display the target partial image corresponding to the target image signal.

[0102] Exemplarily, the light modulator may include a plurality of micromirrors, and when the light modulator in the projection device is controlled by the target control signal, the flipping state of the micromirrors in the light modulator corresponding to the target image signal may be controlled. An incident light beam is present on the micromirror, and thus, the incident light beam is modulated by the corresponding micromirror in the light modulator assembly, so that the light beam reflected by the micromirror can form a target partial image corresponding to the target image signal, so as to display the target partial image.

[0103] As described in the above embodiments, the light beam reflected by the micromirror can form a partial image of the template through the lens.

[0104] When the target partial image is displayed, the following steps can be performed:

[0105] S804. Control the optical modulation device to sequentially display partial images corresponding to the remaining multiple image signals using control signals corresponding to the remaining multiple image signals to display the image to be displayed. The control signals corresponding to the remaining multiple image signals are multiple control signals generated sequentially based on the remaining multiple image signals.

[0106] When displaying the target partial image, the partial image corresponding to the image signal can be displayed according to another image signal by the method described in step S803. Thus, each image signal is displayed in turn by the method described in step S803 to display the image to be displayed.

[0107] In this way, the display method provided by the embodiment of the present application can display the entire frame of the image by sequentially displaying partial images of the image to be displayed. When the projection device displays a new frame of the image, a part of the new image can be displayed in a shorter time, so that the user can see the image changes in a shorter time, which can improve the user experience.

[0108] As shown in the structural diagram of the projection device above, in the embodiment of the present application, the light source assembly in the projection device can emit light beams of multiple colors. When displaying a target partial image, it is necessary to use a superposition display of multiple colors. In this way, each color of the light beam can correspond to a sub-control signal. Therefore, the target control signal can include multiple sub-control signals, and the sub-control signals correspond to multiple colors one by one. For example, when the light source assembly can emit light beams of three colors, R, G, and B, the target control signal may include a sub-control signal corresponding to the R color, a sub-control signal corresponding to the G color, and a sub-control signal corresponding to the B color.

[0109] Exemplarily, the light source assembly can sequentially and time-sequentially cause light beams of multiple colors to be incident on the light modulator; when each color light beam is incident on the light modulator, the light modulator can be controlled according to a sub-control signal corresponding to the light beam of that color to display a target partial image of the color based on the light beam of that color, so as to display the target partial image corresponding to the target image signal.

[0110] In this way, the light modulator can be controlled by sub-control signals corresponding to light beams of different colors, so that the light modulator can display a target partial image by superimposing light beams of multiple colors under the control of multiple sub-control signals.

[0111] In an embodiment of the present application, the light modulator may include multiple micromirrors. According to a sub-control signal corresponding to the color light beam, the light modulator is controlled to display a target partial image of color based on the color light beam. According to the sub-control signal corresponding to the color light beam, the state of a micromirror group corresponding to the sub-control signal in the multiple micromirrors can be refreshed. The color light beam incident on the micromirror group is reflected by the micromirror group, and the color target image is displayed by the reflected light beam. The micromirror group includes at least 2 micromirrors.

[0112] The state of the micromirror group may include the flip angle of the micromirror group, the duration for which a certain flip angle is maintained, etc., which is not limited in the embodiments of the present application.

[0113] In this way, by specifically controlling the state of the micromirrors in the light modulation device, the projection device can display a partial image of the image to be displayed.

[0114] In the embodiment of the present application, when a target partial image is generated by using multiple colors, it is necessary to control the light source assembly to emit light beams of corresponding colors to the light modulation device in sequence.

[0115] Exemplarily, light source control signals corresponding to light beams of multiple colors can be generated according to a target image signal among multiple image signals; and the light source assembly is controlled to emit light beams of corresponding colors according to the light source control signals corresponding to the light beams of each color in a time sequence, so that the light beams of corresponding colors are incident on the light modulation device.

[0116] For example, when the light source assembly can emit light beams of three colors, R, G, and B, a light source control signal corresponding to the color R, a light source control signal corresponding to the color G, and a light source control signal corresponding to the color B can be generated. In this way, the light source assembly can be controlled to emit light beams of three colors, R, G, and B, in sequence.

[0117] As described in the above embodiment, the number of image signals is n as an example, and the process of the projection device displaying the image to be displayed can be as follows: Fig. 9 As shown, Fig. 9 A schematic diagram of a process of displaying an image frame through a light modulation component provided in an embodiment of the present application.

[0118] like Fig. 9 As shown, the light modulation controller can obtain multiple image signals of the image to be displayed in the multimedia module each time, and sequentially cache n image signals of the frame image, and control the light modulation component to display 1 / n each time 1 / n image frames are cached. Repeat the above steps to realize the display of the image to be displayed.

[0119] Correspondingly, taking the display frequency of the projection device as 60 Hz as an example, the timing of caching image frames and displaying image frames can be seen in Fig.10 As shown, Fig.10A timing diagram of an optical modulation component displaying an image provided in an embodiment of the present application.

[0120] When the display frequency of the projection device is 60Hz, the time to cache one frame of image and display one frame of image is 16.7ms, and the time to display 1 / n image is 1.67 / n ms. Fig.10 As shown, in the time period of 0-16.7ms, the light modulation controller caches image frame 2, and the light modulator can start to display image frame 2 after 1.67 / n ms. In the time period of 16.7ms-33.4ms, the light modulation controller caches image frame 3, and the light modulator can start to display image frame 3 after 18.37 / n ms. In the time period of 33.4ms-50.1ms, the light modulation controller caches image frame 4, and the light modulator can start to display image frame 4 after 35.07 / n ms.

[0121] Taking the light source component emitting three color beams of R, G, and B, and the number of image signals as n as an example, the process of the projection device displaying the image to be displayed can be seen in Fig.11 As shown, Fig.11 A schematic diagram of a process for displaying an image to be displayed provided in an embodiment of the present application.

[0122] like Fig.11 As shown, when displaying 1 / n frame images in the image to be displayed, the light source assembly emits a light beam of color B under the control of the light source control signal, and after the switching of light beams of different colors is completed, the B component of the target image signal can be refreshed. When the B component is refreshed, the light source assembly can be controlled to emit a light beam of color R, and after the switching of light beams of different colors is completed, the R component of the target image signal can be refreshed. When the R component is refreshed, the light source assembly can be controlled to emit a light beam of color G, and after the switching of light beams of different colors is completed, the G component of the target image signal can be refreshed to complete the display of the 1 / n frame image.

[0123] It can be understood that the process of refreshing different components of the target image signal is similar to the process of controlling the display of target partial images of different colors described in the above embodiment, and will not be described in detail here.

[0124] exist Fig.11 When the R component is refreshed, the light source assembly can be controlled to emit a light beam of color B, so as to display a 2 / n frame image through the color B.

[0125] like Fig.11As shown, after the display of 1 / n frame images is completed, the display of 2 / n frame images, the display of 3 / n frame images, ..., the display of 1 frame images can be further completed, thereby completing the display of the image to be displayed. Among them, the display process of 2 / n frame images, 3 / n frame images, ..., etc. is similar to the process of 1 / n frame images.

[0126] In an embodiment of the present application, the number of signals of multiple images may be related to the switching duration of the light source assembly so that the display duration is greater than the switching duration. The switching duration is the duration for switching light beams of different colors, and the display duration is the duration for controlling the display of the corresponding image according to each image signal.

[0127] For example, when the light source component is a laser, the laser needs to be controlled to switch colors, and the time required to display 1 / n frames of images must be longer than the time it takes for the laser to switch colors.

[0128] In this way, while the light modulation device is controlled according to control signals corresponding to different colors, the laser can emit a light beam of that color to the light modulation device to display an image of the corresponding color based on the incident light beam.

[0129] In the embodiment of the present application, since different scenes have different delays in image display, the signal of the image to be displayed can be divided into different numbers of parts for different scenes, that is, in different scenes, the signal of a frame of image can include different numbers of image signals.

[0130] The more multiple image signals included in the signal of the image to be displayed, the faster the user can see the screen switching. Therefore, the number of multiple image signals may be related to the scene of the projection device, and the number corresponding to the game scene is greater than the number corresponding to other scenes.

[0131] In this way, in scenes with high latency requirements, the time when the image starts to be displayed is shorter than the time when the image starts to be displayed in scenes with low latency requirements. In game scenes with high latency requirements, users can see the changes in the picture faster, improving the user experience.

[0132] In the embodiment of the present application, the corresponding relationship between the scene and the number of image signals may be pre-stored in the projection device. When the projection device is in the game scene, the signal of the image to be displayed is obtained, and the signal of the image to be displayed is divided into a first number of image signals according to the first number of image signals corresponding to the game scene. For example, when the number corresponding to the game scene is 10, when it is detected that the projection device is in the game scene, the signal of the image to be displayed may be obtained, and the signal of the image to be displayed may be divided into 10 image signals.

[0133] In this way, for different scenes, users can see the switching of images at different times, which does not affect the user experience and can reduce the number of times the light source component switches light beams of different colors.

[0134] The present application also provides a computer-readable storage medium, which may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, and other media that can store program codes. Specifically, the computer-readable storage medium stores program instructions, and the program instructions are used for the methods in the above embodiments.

[0135] The present application also provides a program product, which includes an execution instruction, which is stored in a readable storage medium. At least one control module of the projection device can read the execution instruction from the readable storage medium, and at least one control module executes the execution instruction so that the projection device implements the display method provided by the various embodiments described above.
