Abstract: A carrying structure is provided and is defined with a main area and a peripheral area adjacent to the main area, where a plurality of packaging substrates are disposed in the main area in an array manner, a plurality of positioning holes are disposed in the peripheral area, and a plurality of positioning traces are formed along a part of the edges of the plurality of positioning holes, such that the plurality of positioning traces are formed with notches. Therefore, a plurality of positioning pins on the machine can be easily aligned and inserted into the plurality of positioning holes by the design of the plurality of positioning traces.

Abstract: A display system supporting a privacy function and a display control method are disclosed. The method includes the following. A first light source driving signal is provided to a display through a first signal path of a switch circuit to drive the display to display a first image in a first display mode. A trigger signal is generated in response to a user operation. A second light source driving signal is provided to the display through a second signal path of the switch circuit in response to the trigger signal to drive the display to display a second image in a second display mode. The first signal path is different from the second signal path. A screen brightness of the display in the second display mode is lower than a screen brightness of the display in the first display mode.

Abstract: An optical recording apparatus includes an optical pickup unit for generating and directing optical signals onto a given optical medium, and for detecting corresponding reflected optical signals from the optical medium; a focus motor for moving a focusing lens on the optical pickup according to a focus signal for adjusting a defocus of the optical signals on the optical medium; and a focus controller for generating the focus signal. During write operations of the optical recording apparatus, the focus controller is for performing write defocus calibration on the given optical medium to determine an optimal write defocus value for the optical medium. If the optical medium has multiple layers, the write defocus calibration is performed on a particular layer of the optical disc toward which write operations are directed. If the optimal defocus write value is different than a starting write defocus value, an updated write defocus value is stored.

Abstract: An electronic apparatus is disclosed. The electronic apparatus includes an electronic device, a supporting base, at least a fixing member and at least a protrusion structure. The electronic device has at least a first fixing hole. The supporting base has at least one supporting rod, wherein the supporting rod has at least a second fixing hole. The fixing member is inserted through the first fixing hole and the second fixing hole. The protrusion structure is positioned on the supporting rod and is positioned between the electronic device and the supporting rod such that the center of gravity of the electronic device is shifted to substantially coincide with that of the supporting base to steadily position the electronic device on the supporting base.
