A control circuit of universal serial bus (USB) port includes a charge control unit providing a first operating voltage and a second operating voltage to a first operating voltage end and a second operating voltage end of the USB port, and a first circuit unit coupled to the charge control unit. Furthermore, the first circuit includes a first output end and a second output end. When a external apparatus is inserted into the USB port, the charge control unit connects the first output end and the second output end to a differential positive end and a differential negative end of the USB port, respectively, to enter a rapid charging mode.

A battery includes a casing, a battery pack, and at least two electrical connecting assemblies. The casing includes an inner space and plural contact planes. Vertical directions of the contact planes are different. The battery pack includes a battery cell disposed in the inner space, and the battery cell includes a positive and a negative electrodes. The electrical connecting assemblies are electrically connected to the positive electrode and the negative electrode respectively, so as to transmit power between the battery pack and an electronic device. The electrical connecting assembly electrically connected to the positive electrode is arranged on at least two of the contact planes, and the electrical connecting assembly electrically connected to the negative electrode is arranged on at least two of the contact planes. If power supply in one certain direction is interrupted, the battery transmits power in the other directions, thereby avoiding power supply from being interrupted.

An electronic device with supporting stands includes an input/output module, two stands and a limiter. The two stands are obliquely disposed on the back side of the input/output module. The stands are limited by the limiter to move synchronously. At the same time, the limiter has two slots penetrated by the stands to limit moving range for the stands. Then the stands are controlled to swing with an angle and finally the visual angle of the input/output module is varied in suitable range.

A three-dimensional display apparatus and a data processing method thereof are provided. The three-dimensional display apparatus includes a data processing module. The data processing module includes an image comparison unit and an image compensation unit. The image comparison unit receives a first eye frame and a second eye frame in order, compares a plurality of first gray-scale data of the first eye frame with a plurality of second gray-scale data of the second eye frame respectively, and outputs a plurality of comparison results. The image compensation unit is coupled to the image comparison unit and generates a compensation frame corresponding to the second eye frame according to the comparison results. Therefore, image sticking can be avoided.

A portable electronic device with switchable input/output portions is provided. A control portion is disposed at a main body module of the portable electronic device, and it includes multiple input/output portions. Only one of the input/output portions is exposed out of the main body module to allow the user to operate. In addition, the user may switch the input/output portions corresponding to different modes by rotating, sliding and other operations. This is not only space-saving, but also facilitates the operation of the user.

A portable electronic device includes a screen module, a main body module and an input/output module. The screen module is pivotally connected with the body module. The input/output module is electrically connected with the main body module. An actuating element is disposed at a bottom of the screen module. When the screen module is opened respectively to the body module to be opened, the actuating element is driven to swing to push a front end of the input/output module to be lifted to drive the input/output module to be out of a state that the keyboard abuts against the main body module. Therefore, the portable electronic device is easy to be operated. Moreover, the heat dissipation is improved to keep the internal temperature low and reduce energy consumption.
