The first-conductivity-type contact structure is electrically connected to the first semiconductor contact layer. The second-conductivity-type contact structure is electrically connected to the second semiconductor contact layer. The first-conductivity-type contact structure has a first bottom surface and a first top surface, and the active layer has a second bottom surface and a second top surface.

Abstract: A head-mounted display device includes a main body and a first simulator connected to the main body. The first simulator includes multiple nozzles, multiple air channels, a first fan, and multiple regulators. The nozzles face the user's eyes. The first fan is configured to drive external air to flow to the corresponding nozzles through the air channels. The regulators are disposed between the air channels and the corresponding nozzles to independently regulate the flow rates of air jetted from the nozzles.

Abstract: A head-mounted display device and an external adjustment module are provided. The head-mounted display device includes a body and the external adjustment module. The body has a first lens and a second lens corresponding to both eyes, and also has a driven mechanism. The first lens and the second lens are respectively coupled to the driven mechanism. The external adjustment module includes a driving element and a transmission element. The transmission element is assembled to the driving element and used for coupling to the driven mechanism. The driving element is used for driving the driven mechanism through the transmission element to adjust a distance between the first lens and the second lens.

Abstract: A driving method, suitable for a multimedia system including a head-mounted device (HMD), includes the following operations: retrieving human factor data from a storage device, a radio signal, or an image; and according to the human factor data, automatically adjusting software for driving the HMD or hardware components of the multimedia system.

Abstract: A head-mounted display device includes a housing, a pair of display modules, a pair of cameras, a driving module and a control system. The housing can cover eyeballs of the user. The cameras are respectively fixed to the display modules to capture images of the eyeballs. The driving module is coupled to the display module to move the display modules relative to the housing. The control system is electrically connected to the of cameras and the driving module. An adjustment method is applicable to the above-mentioned head-mounted display device. An image of the corresponding eyeball is captured by one of the cameras. The control system calculates a deviation between a center of a pupil of the corresponding eyeball and a center of the corresponding image according to the image. The control system controls the driving module to move the display modules relative to the housing according to the deviation.
