Abstract: A display device includes the following features. A display panel is disposed in a shell and has a display surface and a back surface. The display surface faces a light-passing portion of the shell, and a first heat dissipation space is formed between the display surface and the light-passing portion. An airflow-blocking plate is disposed in the shell, and a second heat dissipation space is formed among the airflow-blocking plate, the shell and the back surface. A third heat dissipation space is formed between the airflow-blocking plate and the shell. The first heat dissipation space, the second heat dissipation space, the third heat dissipation space, an air inlet and an air outlet of the shell are communicated with each other. A heat-generating assembly is disposed in the second heat dissipation space. A first fan is disposed at the air outlet.

Abstract: An illumination system configured to provide an illumination beam is provided and includes a light-source module and a first and a second wavelength conversion devices. The light-source module provides a first and a second excitation beams. The first wavelength conversion device is disposed on a path of the first excitation beam and has first regions and at least one first boundary disposed between every two adjacent first regions. The second wavelength conversion device is disposed on a path of the second excitation beam and has second regions and at least one second boundary disposed between every two adjacent second regions. The second regions correspond to the first regions. A time point when the first boundary gets into the path of the first excitation beam is different from a time point when the second boundary gets into the path of the second excitation beam. A projection apparatus is also provided.

Abstract: The present application discloses an image capture device, including an image capture unit, a processing unit, and a storage unit. The image capture unit captures a plurality of exposure image during exposure duration. The processing unit is electrically connected to the image capture unit, and the processing unit enables the display unit to display the plurality of exposure images captured by the image capture unit during the exposure duration. The storage unit is electrically connected to the processing unit, and the storage unit controls the storage unit to selectively store at least one of the plurality of the exposure images displayed by the display unit.
