    Abstract: A display panel and a spliced display are provided. The display panel includes a substrate, a plurality of light-emitting elements, a driving circuit, and an optical sensor. The substrate includes a through hole, and the through hole includes a hole. The plurality of the light-emitting elements are disposed on the substrate. The through hole is located in a region between two of the plurality of the light-emitting elements. The driving circuit is disposed on the substrate and electrically connected to the plurality of the light-emitting elements. The optical sensor is disposed corresponding to the through hole and receives sensing light through the hole. The width W of the hole meets the equation of H≤W

    Abstract: A control method applied in a display device is provided. The display device includes an image generator and a screen. The image generator is directed to output an output image. The screen is directed to operate in a first operation mode or a second operation mode. The screen has a first light-transmittance in the first operation mode and has a second light-transmittance in the second operation mode. The first light-transmittance is different from the second light-transmittance. In response to the screen operating in the first operation mode or the second operation mode, the image generator outputs the output image onto the screen in a light-emitting period and stops outputting the output image onto the screen in a non-light-emitting period after the light-emitting period.

    Abstract: A backlight module includes a substrate, light-emitting elements, circuit elements and a reflective sheet. The light-emitting elements are bonded onto the substrate. The circuit elements are bonded onto the substrate and electrically connected to the light-emitting elements. At least four of the light-emitting elements are disposed around one of the circuit elements. The reflective sheet is disposed on the substrate and has first openings exposing the light-emitting elements and protrusions. The protrusions corresponds to the circuit elements and cover the circuit elements. One of the protrusions has an opening formed of two crossing slits. Extending directions of the two crossing slits do not cross the at least four of the light-emitting elements. The one of the protrusions corresponds to the one of the circuit elements. The at least four of the light-emitting elements are closer to the one of the circuit elements than other of the light-emitting elements.
