Abstract: Isolated power supply control circuits, isolated power supply and control method thereof are disclosed, the control circuit for controlling an isolated power supply includes a secondary-side control signal generator and a primary-side control signal generator. The secondary-side control signal generator produces a secondary-side transistor switch control signal containing information about a turn-off instant of a secondary-side synchronous rectification transistor, which serves as a second turn-on instant. The primary-side control signal generator derives, from a feedback signal, a supposed turn-on instant for a primary-side transistor switch, which serves as a first turn-on instant. The primary side turn-on signal generator further derives a turn-on instant for the primary-side transistor switch from the second or first turn-on instant whichever is later and responsively generates a primary-side transistor switch control signal.

Abstract: Disclosed is a watch, including a main body and a watch strap. The main body includes a middle frame and a decorative ring; the middle frame is provided with a sliding groove; an outer wall of the middle frame is provided with a watch strap insertion opening that is communicated with the sliding groove; the decorative ring is rotatably connected to the middle frame; the decorative ring is provided with a latch portion; the latch portion extends into the sliding groove; an end of the watch strap is provided with a latch engagement portion; at least the latch engagement portion can be inserted into the sliding groove through the watch strap insertion opening; and the decorative ring has a first location and a second location relative to the middle frame.

Abstract: A gamma correction method and an apparatus. In the method, RGB adjustment values corresponding to a target binding point are determined through RGB measurement values of a previous binding point of a corresponding target binding point at low-grayscale fault for an OLED module to be corrected, and then voltages of the target binding point are determined according to the RGB measurement values and the RGB adjustment values, and gamma correction is performed on the OLED module to be corrected according to the voltages of the target binding point, resolves the problem of low-grayscale fault caused in terms of the low-grayscale binding point correction. Moreover, the correction process of the embodiments of the present application is simple where a low-grayscale binding point is corrected using the above-mentioned method, and a high-grayscale binding point is automatically adjusted using an optical device, without changing the gamma correction architecture.

Abstract: The present application relates to a display device. The display device includes a body; a display screen disposed on the body. The display screen includes a first display region and a light transmissive region. The first display region has a light emitting surface facing away from the body, a light receiving module located between the display screen and the body, a second display region disposed between the display screen and the body, and the second display region is configured to compensate the light transmissive region to display image information in the light transmissive region; and a light path structure positioned between the display screen and the body.
