  • Publication number: 20250251108
    Abstract: An illumination system includes a first light source, a second light source and an operation processor. The first light source provides a first illumination range. The second light source provides a second illumination range partly overlapped with the first illumination range. The operation processor is electrically connected to the first light source and the second light source. The operation processor can adjust a first lighting parameter of the first light source to be different from a second lighting parameter of the second light source, so as to reduce or eliminate a flicker phenomenon in an overlapping illumination range between the first illumination range and the second illumination range.

  • Publication number: 20250146643
    Abstract: An illumination module includes a light source configured to emit an illumination light beam, a reflective light valve disposed on a path of the illumination light beam and configured to form a plurality of pixels, a lens, and an image sensing module. Each pixel is adapted to be switched between a first state and a second state. The pixels in the first state among the pixels are configured to reflect the illumination light beam into an effective light beam. The pixels in the second state among the pixels are configured to reflect the illumination light beam into a complementary light beam. The lens is disposed on a path of the effective light beam and configured to project the effective light beam to an area to be illuminated. The image sensing module is disposed on a path of a complementary light beam from the reflective light valve and configured to sense the complementary light beam.

  • Publication number: 20250140189
    Abstract: A pixel circuit and a display device are provided. The pixel circuit includes a light-emitting component, a first light sensor, and a variable resistor. The first light sensor receives a first operation voltage, and provides a first control voltage according to an intensity of a first sensed light. The variable resistor adjusts a resistance value provided therefrom according to the first control voltage so as to adjust a current value of a driving current flowing through the light-emitting component.

  • Publication number: 20250110609
    Abstract: A computer operating system is provided. The computer operating system includes a control host, a display device, and a mouse. The display device is connected to the control host. The mouse is connected to the control host. The control host is used to generate a first mouse icon on the display device and generate a second mouse icon on the display device when the first mouse icon exists, wherein a pattern of the first mouse icon is different from a pattern of the second mouse icon.

  • Publication number: 20250054452
    Abstract: The invention provides a display device and an operation method thereof. The display device includes a calculation unit and a local dimming driving unit. The calculation unit generates image data for displaying on a display panel. The calculation unit determines a location of a mouse pointer (cursor) in the image data based on an operation of a user interface device. The calculation unit defines an attention area corresponding to the mouse pointer based on the location of the mouse pointer. Based on information of the calculation unit, the local dimming driving unit enables a local dimming function for the attention area corresponding to the location of the mouse pointer, or disables the local dimming function for a non-attention area outside the attention area.

  • Patent number: 12181120
    Abstract: An illumination module includes a light source, a reflective light valve, a lens, and a diffuser. The light source is configured to emit an illumination beam. The reflective light valve is disposed on a path of the illumination beam, and includes multiple pixels. A pixel in a first state among the pixels is configured to reflect the illumination beam into an effective beam. A pixel in a second state among the pixels is configured to reflect the illumination beam into an auxiliary beam. The lens is disposed on a path of the effective beam, and configured to project the effective beam to an area to be illuminated. The diffuser is configured to diffuse the auxiliary beam from the reflective light valve into a diffused light. The lens is configured to project the diffused light to the area to be illuminated.

  • Patent number: 10967798
    Abstract: A control device and a method for image display are provided. The control device includes a mirror display unit, a backward camera unit, a reference data detection module, and an image processing module. The mirror display unit includes a mirror and a display module. The mirror generates a first image via reflection. The display module has a display surface at least partially overlapping with the mirror. The backward camera unit captures a second image, and the area of the first image is within the area of the second image. The reference data detection module generates reference data. The image processing module determines an area correspondence between the first image and the second image according to the reference data, and generates a display image from the second image based on the area correspondence. The display module displays the display image when receiving a switch command.
