    摘要: A multi-screen splicing structure has a plurality of display devices. Each display device includes a display panel, a plurality of transceivers, a wireless communications module, and a control circuit. Each transceiver has a transmitting component and a receiving component. The control circuit is coupled to the display panel, the transceivers and the wireless communications module, and is used to turn on the wireless communications module when the control circuit determines that another display device is approaching based on a status of signals received by the receiving components of the transceivers to enable the wireless communications module performing wireless communications with a wireless communications module of another display device. The control circuit may also control an orientation of an image relative to the display panel according to the status of signals received by the receiving components of the transceivers of the display device.

    摘要: A projection system including at least a light source, at least a dichroic filter element and a light-adjusting diaphragm element is provided. The light source is configured to emit a first color light having a spectrum of a first wavelength range and a second color light having a spectrum of a second wavelength range. The dichroic filter element is configured to reflect or allow the first color light and the second color light to pass through. The light-adjusting diaphragm element has a filter and is located on an optical path generated after the first color light and the second color light are split. The first color light passes through the filter, which blocks at least a part of the energy of the second color light, such that a transmittance of the spectrum of the first wavelength range is greater than that of the spectrum of the second wavelength range.

    摘要: A sensing device for sensing a backlight density of a panel module is disclosed. The panel module includes a panel, a back plate and a holding frame. The back plate has an opening formed thereon and is for installing the panel onto the holding frame. The sensing device includes a sensor module and a base. The sensor module is for sensing a light projected via the opening and generated by the panel. The base is disposed between the back plate and the holding frame. The base includes a main body and a resilient structure. The main body is for containing the sensor module. The resilient structure extends from the main body and resiliently abuts against the holding frame. The resilient structure presses the main body onto the back plate when resilient abutting against the holding frame, such that the back plate and the main body cooperatively covers the sensor module.

    摘要: A method capable of automatically switching operation modes is applied to a multi-functional mouse device which has a first operation mode and a second operation mode. The multi-functional mouse device can move over a plane formed by a first axis and a second axis perpendicular to each other, and includes a coordinate positioning unit suitable for the second operation mode. The method includes detecting whether the coordinate positioning unit generates a first axial signal, detecting whether the coordinate positioning unit generates a second axial signal within a first predetermined period, determining whether continued time of the first axial signal and the second axial signal exceed over a second predetermined period, and determining whether the multi-functional mouse device is switched from the first operation mode to the second operation mode according to a determination result.

    摘要: A projector and a projecting method using the same are provided. The projector includes a first light source, a color wheel and a second light source. The first light source is configured to emit a first color light. The second light source is configured to emit a second color light. The first color light passing through a transparent region of the color wheel becomes a third color light. The second color light and the third color light are mixed as a first projecting light. The first color light reflected by a phosphor reflection region of the color wheel becomes a fourth color light. The fourth color light is guided toward a projecting direction to become a second projecting light. The first projecting light and the second projecting light do not overlap in timing.

    摘要: The present invention provides a display supporting device for supporting a display module. The display supporting device includes a stand, a moving part, and an indicating device. The moving part is disposed on the stand and movable between a first position and a second position for connecting the display module with the stand. The indicating device is disposed on the stand and indicates the position of the moving part relative to the stand. The indicating device is able to record the rotating angle or moving distance of the moving part. The display module can be adjusted back to a recorded angle or position in accordance with the indicating device when the display module changes its angle or position.
