A laser projection apparatus is provided and includes an optical modulating assembly, a vibrating device, a projection lens, and a circuit architecture. The circuit architecture includes an image processing sub-circuit and a display driving sub-circuit. The image processing sub-circuit is configured to perform frame division on image data of an image to be displayed to obtain image signals of a plurality of frames of sub-images to generate a frame division control signal. The display driving sub-circuit is configured to output the image signals of the plurality of frames of sub-images to the optical modulating assembly and output a vibration instruction to the vibrating device based on the output timing of the image signals of the plurality of frames of sub-images, so as to control the vibrating device to perform vibrations, so that the projection beams are output through the vibrating device.

Laser projection apparatus, projection display system, and projection display method

A display apparatus includes a display; a remote controller; a controller. The controller is configured to receive a first command for fitness training, cause the display to present one or more modes including a follow-up mode and an exercising-while-watching mode for selection; in response to selection of the follow-up mode, cause the display to show a first window and a second window disposed on a first user interface for receiving a focus move command from the remote control, with the first window displaying a first video associated with fitness training and the second window displaying a second video associated with image data from a camera; receive a volume adjustment command; in response to the focus being on a volume control for the first or second video, adjust a volume of the first or second video in response to the volume adjustment command. A method for controlling the apparatus is disclosed.

Display device and volume control method

A projection display system includes a control assembly, an optical path changing device, a light source assembly, a digital micromirror device, and a projection lens. The control assembly is configured to determine whether a resolution of an image to be projected is greater than a preset resolution. If the resolution of the image to be projected is greater than the preset resolution, the control assembly divides the image to be projected into N sub-images, wherein N is greater than or equal to 2. For each sub-image: the control assembly is further configured to determine a first signal, a second signal, and a third signal according to the sub-image, send the first signal to the light source assembly, send the second signal to the digital micromirror device, and send the third signal to the optical path changing device. The projection lens is configured to project the N sub-images at different times.
