Abstract: A method for controlling a display device includes establishing a data link between the display device and a hardware dongle, generating a second interface by the display device through the hardware dongle after the data link is established, generating a control signal by the display device through the second interface, and executing at least one function according to the control signal. A first interface is stored in the display device. The first interface and the second interface are different. At least one first function is supported by the display device. At least one second function is supported by the hardware dongle. The at least one first function and the at least one second function are integrated for generating the second interface by the display device after the data link is established.

Abstract: A projection system includes a plurality of projection units, a sensing module and a processing unit. The projection units project a plurality of images. The sensing module senses a current optical parameter of each of the images to obtain a plurality of current optical parameters. The processing unit communicates with the projection units and the sensing module. The processing unit receives the current optical parameters from the sensing module, determines a target optical parameter according to the current optical parameters, and transmits a control signal to each of the projection units. Each of the projection units adjusts the current optical parameter to the target optical parameter in response to the control signal.

Abstract: 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.

Abstract: An image display method for handling a dynamic image signal including a plurality of continuous video frames, wherein the method includes steps as follows: Firstly, a first display parameter is output to display an Nth video frame of the plurality of continuous video frames according to a first attribute data of the Nth video frame. Then, at least one of (N+K)th video frame is detected, and when the at least one of the (N+K)th video frame has second attribute data, the first display parameter is output to display the at least one of the (N+K)th video frames. Subsequently, an (N+K+1)th video frame is detected, and when the (N+K+1)th video frame has the second attribute data, a second display parameter is output to display the (N+K+1)th video frame according to the second attribute data. Wherein, K is a positive integer greater than 1.
