Abstract: A backsheet of a solar cell module including a substrate, a first protection layer, and a second protection layer is provided. The substrate includes a first surface and a second surface opposite to each other. The first protection layer is disposed on the first surface of the substrate. The second protection layer is disposed on the second surface of the substrate, wherein the first protection layer and the second protection layer include a silicone layer. At least one of the first protection layer and the second protection layer includes diffusion particles, wherein the diffusion particles include zinc oxide, titanium dioxide modified with silicon dioxide, or a combination thereof. A thickness of the first protection layer and a thickness of the second protection layer are respectively 10 ?m to 30 ?m. A solar cell module including the backsheet is also provided.

Abstract: A format conversion circuit applied to a set-top box (STB), which is coupled to a display device, is disclosed. The format conversion circuit includes an electro-optical transfer function (EOTF) circuit, a mapping circuit and an opto-electronic transfer (OEFT) circuit. The EOTF circuit converts an input image signal having a first format to a first optical signal. The mapping circuit, coupled to the EOTF circuit, converts the first optical signal to a second optical signal having a second format, wherein at least one of the first optical signal and the second optical signal is generated according to a maximum luminance of the display device. The OETF circuit, coupled to the mapping circuit, converts the second optical signal to an output image signal.
