Abstract: This disclosure relates to display adjustment methods and head-mounted display devices. The head-mounted display device includes: first and second display modules; a first adjustment unit for triggering the first display module to enter a diopter adjustment mode and/or an interpupillary distance adjustment mode and for triggering the second display module to enter a non-adjustment mode; a confirmation unit for receiving a confirmation signal indicating that the first adjustment unit has completed the adjustment; a second adjustment unit for triggering the second display module to enter the diopter adjustment mode and/or the interpupillary distance adjustment mode and for triggering the first display module to enter the non-adjustment mode after the confirmation unit has received another confirmation signal.

Abstract: The present application refers to a head-mounted electronic device including a headphone, a display portion, and two position limiting structures. The headphone includes a C-shaped elastic belt which has two connection ends, two movable members, each rotatably connected to one connection end around a first axis, and two sound generators, each rotatably connected to one movable member around a second axis. The display portion includes a main body generating and projecting images, and two connection members connected to opposite ends of the main body. Each of the two connection members is rotatably connected to the sound generators around a respective third axis. When rotating around the third axis, the headphone is driven by the display portion to rotate around the first axis and the second axis, which avoids distortion of the elastic belt and the connection member, and ensures the display portion can be folded together with the headphone.

Abstract: A capacitive touchscreen includes a substrate and a transparent conductive layer arranged on the substrate. The conductive layer includes a sensing area. The sensing area has a first side and a second side opposite to the first side. The capacitive touchscreen further includes multiple transparent and conductive first electrodes, multiple transparent and conductive second electrodes, and transparent and nonconductive patterns. Each first electrode includes a first trunk extending from the first side toward the second side. Each second electrode includes a second trunk and a wiring coupled to the second trunk. Both the second trunk and the wiring extend from the first side toward the second side, and each second trunk cooperates with a corresponding first trunks to be operable to sense a touched position. The transparent and nonconductive patterns are located between the first and second electrodes to electrically isolate the first electrodes from the second electrodes.
