Abstract: Provided are a driver board, a display panel, and a display apparatus. The driver board includes a driver circuit. The driver circuit includes N pixel electrodes, N pixel switches, a data switch, and a storage capacitor, N is a positive integer, and N?2. The storage capacitor includes a reference electrode and a counter electrode. A control terminal of the pixel switch receives a gating signal, a first terminal of the pixel switch is connected to the counter electrode, and a second terminal of the pixel switch is connected to the pixel electrode. The driver board further includes data lines, and each data line is connected to the counter electrode via the data switch.

Abstract: A solderless battery pack is provided that includes a battery port, a protective plate, an upper end plate, a lower end plate, cell groups and a cell locking mechanism. The cell groups are arranged between the upper end plate and the lower end plate and include a cell installation bracket, cells and a PCB busbar. The cell locking mechanism includes a metal upper pressing plate, a metal lower pressing plate and a fastening long bolt that passes through the metal upper pressing plate, the metal lower pressing plate, the upper end plate, the lower end plate and the cell groups.

Abstract: Disclosed are a virtual clothing changing method and apparatus. One specific embodiment of the method comprises: extracting foot images from a target image in which the feet are displayed; generating foot posture information on the basis of the foot images; and on the basis of the foot posture information, superimposing a clothing pattern onto the feet displayed in the target image. The embodiment not only makes it convenient for a customer to buy suitable clothing, but also ensures the accuracy of virtual clothing changing, thereby facilitating an improvement in the experience of the customer buying the clothing.

Abstract: The disclosure provides a locking and separating mechanism capable of achieving sequential release of multiple satellites and a working method thereof.

Abstract: The method for collecting information includes obtaining, based on a method identifier of the target method, the quantity of times of invoking the target method, recording method information of the target method based on the quantity of times of invoking the target method, a first threshold, and a second threshold, and setting a method status of the target method, the method status is one of a first state and a second state, the first state corresponds to the first threshold, the second state corresponds to the second threshold.

Abstract: The disclosure provides a locking and separating mechanism capable of achieving sequential release of multiple satellites and a working method thereof.

Abstract: The method for collecting information includes: when a quantity of times of invoking a target method in a running lifecycle of a target program increases, obtaining, based on a method identifier of the target method, the quantity of times of invoking the target method; and recording method information of the target method based on the quantity of times of invoking the target method, a first threshold, and a second threshold, and setting a method status of the target method, the method status is one of a first state and a second state, the first state corresponds to the first threshold, the second state corresponds to the second threshold.
