  • Patent number: 12375754
    Abstract: A display device and a signal source switching method therefore are provided. The display device is connected with a first signal source device and a second signal source device and includes a switching circuit, a receiver circuit and a control circuit. The switching circuit includes a first connection port and a second connection port, which are respectively connected to the first signal source device and the second signal source device. When the control circuit receives a signal source switching command, the control circuit records a current operating state of each of the first signal source device and the second signal source device. When the control circuit receives an active source command from the first signal source device, the control circuit refers to the current operating state to control the switching circuit to switch the image signal source to the first signal source device or the second signal source device.

  • Publication number: 20250138774
    Abstract: This disclosure provides a display device and an audio playing method. The display device includes a processor, a first communication interface, and a second communication interface. The first communication interface is electrically connected to the processor and a player device. The second communication interface is electrically connected to the processor. In response to the processor receiving an audio detection command from the player device through the first communication interface, the processor determines whether a connection port of the second communication interface has a preset voltage. In response to the processor determining that the connection port of the second communication interface does not have the preset voltage, the processor responds to the audio detection command to occupy an audio system logical location. In response to the processor determining that the connection port of the second communication interface has the preset voltage, the processor ignores the audio detection command.

  • Publication number: 20240045317
    Abstract: A method includes forming a reflective multilayer over a substrate; depositing a first capping layer over the reflective multilayer, wherein the first capping layer is made of a ruthenium-containing material or a chromium-containing material; performing a treatment to the first capping layer to introduce nitrogen or fluorine into the first capping layer; forming an absorption layer over the first capping layer; and patterning the absorption layer.

  • Publication number: 20240045318
    Abstract: An extreme ultraviolet (EUV) mask includes a substrate, a reflective multilayer stack on the substrate, a diffusion barrier layer, a capping layer and a patterned absorber layer. The reflective multilayer stack comprises alternately stacked first layers and second layers. The diffusion barrier layer is on the reflective multilayer stack. The diffusion barrier layer has a composition different from compositions of the first layers and the second layers. The capping layer is on the diffusion barrier layer. The patterned absorber layer is on the reflective multilayer stack.
