These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0037] Figure 1 1 is a schematic structural diagram of a laser projector in the related art. The laser projector includes a laser projector driving device 11, an optical lighting device 12 and an optical engine 13.

[0038] The laser projector driving device 11 includes a display panel 111, a laser driving component 112 and a color wheel driving component 113. The display panel 111 is respectively connected to the optical engine 13, the color wheel driving component 113 and the laser driving component 112, and is used to receive a video signal and process the video signal into a color control signal, and then control and drive the optical engine 13, the color wheel driving component 113 and the laser driving component 112 accordingly based on the color control signal.

[0039] In addition, the laser projector driving device 11 may further include a mainboard 114 , which may also be referred to as a TV board.

[0041] However, the laser projector driver uses the display panel 111 to process images, and the display panel 111 is usually a matching component with the optical engine 13, the color wheel drive assembly 113, and the laser drive assembly 112, making it difficult to replace. This makes it difficult to improve the image processing capabilities of the laser projector driver and the maximum resolution of the image beam that the laser projector driver can project difficult to improve. Currently, the resolution requirements for images projected by laser projectors are getting higher and higher, such as 8K (which can be 7680*4320) resolution. However, most current display panels have difficulty processing 8K video signals, which greatly limits the development of laser projectors.

[0042] The embodiments of the present application provide a laser projector driving device and a laser projector, which can solve the problems existing in the above-mentioned related technologies.

With such a structure, the video signal can be processed by a high-performance image processing component. For example, an 8K video signal can be processed by an image processing component capable of processing 8K video signals, and the processed color control signal is sent to the display panel. The display panel then drives the optical engine and other structures based on the color control signal, so that 8K video playback can be achieved on the laser projector, breaking through the bottleneck of 8K resolution.

The signal conversion board 26 is configured to receive a video signal in a first format and convert the first format video signal into a second format video signal that matches the image processing component 22. Specifically, the signal conversion board 26 receives the video signal in the first format and inputs a second format video signal that matches the image processing component 22 to the image processing component 22. Matching here can be considered to be a format that the image processing component 22 can process, i.e., a format that the image processing component 22 matches.

The specific implementation method of the frame rate conversion chip 272 can include performing calculations on two adjacent images, and the processor generates a transition image between the two images to achieve a smoother visual effect.

[0078] Optionally, the control component 21 includes a microcontroller unit (MCU) 211 and a flash memory (Flash) 212. The MCU 211 is connected to the flash memory 212 and the system-on-chip 271 respectively. The flash memory 212 is used to store the digital light processing (DLP) program.

[0080] The laser projector used in the laser projector driving device provided in the embodiment of the present application may have a three-color laser, for example, a red laser, a green laser, and a blue laser, and the laser driving component 26 may control the red laser, the green laser, and the blue laser respectively. Exemplarily, the color control signal may be a three-color light signal, and the display panel may obtain the lighting order (Duty) of the red laser, the green laser, and the blue laser and the display brightness duty cycle (PulseWidth Modulation, PWM) information based on the three-color light signal, and the display panel may transmit the information to the laser driving component 26.

[0088] In summary, the laser projector driver device provided in the embodiments of the present application employs independent control components and image processing components within the laser projector driver device. The control component controls the image processing component to process image signals, generating a color control signal. The display panel then controls the light valve component and the laser driver component based on the color control signal. This improves the image processing capabilities of the laser projector driver device by upgrading the image processing component. This solves the problem of difficulty in improving the image processing capabilities of laser projector driver devices in related technologies, thereby facilitating improvements in the image processing capabilities of the laser projector driver device.

[0089] In addition, the laser projector driving device provided in the embodiment of the present application is provided with an independent image processing component and a corresponding control component, and the control component controls the image processing component to process the video signal, and then sends the processed color control signal to the display panel, so that the display panel does not need to directly process the video signal. With such a structure, the video signal can be processed by a high-performance image processing component. For example, an 8K video signal can be processed by an image processing component capable of processing 8K video signals, and the processed color control signal is sent to the display panel.

[0090] Figure 4 FIG2 is a schematic diagram of the structure of a laser projector provided in an embodiment of the present application. The laser projector 5 includes the laser projector driving device 20 provided in the above embodiment.

[0091] In addition, the laser projector 5 further includes an optical illumination device 30 . The optical illumination device 30 includes a laser assembly 31 and a color wheel assembly 32 .

[0092] Optionally, the laser assembly 31 may include a plurality of lasers. For example, the laser assembly 31 may include a red laser, a green laser, and a blue laser.

[0093] The color wheel assembly 32 may also include one or more color wheels, such as at least one color filter wheel and / or at least one fluorescence wheel. The color filter wheel can be used to improve the purity of the light beam emitted by the laser, and the fluorescence wheel is used to emit various colors of light under the stimulation of the light emitted by the laser.

[0094] The color wheel driving assembly 25 in the laser projector driving device 20 can drive each color wheel separately.

[0095] Optionally, the laser projector 5 further includes an optical engine 40, which includes a digital micromirror device (DMD) 41 and a galvanometer 42. The digital micromirror device may include a DMD board and a large number of small lenses located on the DMD board. Exemplarily, the digital micromirror device may be a 0.98-inch digital micromirror device with a resolution of 4K (4096*2160). The galvanometer 42 cooperates with the digital micromirror to achieve an 8K resolution. The galvanometer may be a 4-way galvanometer, that is, a galvanometer that can increase the resolution by 4 times.

[0096] A galvanometer is a device that can improve resolution. For example, when the light beam incident on the galvanometer is a parallel beam (that is, the incident angle of each light ray in the beam is the same), after the optical lens in the galvanometer swings from one position to another, the displacement distance of each pixel of the projected image corresponding to the image beam is equal. This makes the offset of each field of view in the projection lens to the projection screen consistent, which can ensure high-resolution display of the visual image. Among them, the offset of the field of view refers to the actual displacement distance of the field of view. The conversion of 4K resolution to 8K resolution can be achieved by rotating the galvanometer, reducing the difficulty of system design.

[0097] In addition, the laser projector 5 may further include a projection lens, which is used to adjust the light beam emitted by the optical engine 40 and emit the adjusted light beam out of the laser projector 5 to form an image on the screen.

[0098] The display panels in current laser projectors only support processing video data with a maximum resolution of 4K, which limits the maximum resolution that the laser projector can achieve. The 4K resolution has become a resolution bottleneck for laser projectors.

[0099] The laser projector provided in the embodiment of the present application is provided with an independent image processing component and a corresponding control component. The control component controls the image processing component to process the video signal, and then sends the processed color control signal to the display panel, so that the display panel does not need to directly process the video signal. With such a structure, the video signal can be processed by a high-performance image processing component. For example, an 8K video signal can be processed by an image processing component capable of processing 8K video signals, and the processed color control signal is sent to the display panel. The display panel then drives the optical engine and other structures based on the color control signal, so that 8K video playback can be achieved on the laser projector, breaking through the bottleneck of 8K resolution.

[0100] In addition, with the rapid development of current video resolution, higher resolutions will appear in the future, such as 16K, 32K, etc. For the laser projector provided in the embodiment of the present application, the maximum resolution that the laser projector can support can be improved by replacing image processing components with different performance. For example, a more powerful image processing component can be replaced to process 16K and 32K video signals.

[0101] In addition, the laser projector provided in the embodiment of the present application has a simple structure, and the laser projector provided in the embodiment of the present application can be obtained by modifying the existing laser projector. Figure 1 The laser projector shown in the figure has a new microcontroller unit, flash memory and field programmable logic gate array, and is based on Figure 3 By connecting the wires in the manner shown, the laser projector provided in the embodiment of the present application can be obtained. The modification process is relatively simple and the cost is low.

[0102] In summary, the laser projector provided in the embodiments of the present application employs independent control and image processing components within the laser projector driver. The control component controls the image processing component to process image signals, generating a color control signal. The display panel then controls the light valve assembly and the laser driver assembly based on the color control signal. This improves the image processing capabilities of the laser projector driver by upgrading the image processing component. This solves the problem of difficulty in improving the image processing capabilities of laser projector driver devices in related technologies, facilitating improvements in the image processing capabilities of the laser projector.
