Abstract: A flexible circuit board designed for chip integration is provided. The flexible circuit board includes an insulating substrate, a conductive copper layer, a first tin layer, a second tin layer, and a first solder resist layer. The first tin layer has a first tin thickness, and the second tin layer has a greater second tin thickness. A first tin surface of the first tin layer and a second tin surface of the second tin layer are substantially level.

Abstract: A layout structure of a flexible circuit board includes a flexible substrate, a circuit layer and a dummy circuit layer which are arranged on the flexible substrate. The circuit layer includes first inner leads, second inner leads, an inverted U-shape connection line and a horizontal inner lead. A first distance between the first inner leads is less than a second distance between the second inner leads. One of dummy leads of the dummy circuit layer is located between the first and second inner leads, another dummy lead is located between the second inner leads. The dummy leads are provided to allow lead spaces on both sides of the inverted U-shape connection line is the same. Thus, etching solution will not flow laterally in an etching space between the inverted U-shape connection line and the horizontal inner lead.

Abstract: The present invention provides a display device, including: a first chromatic light source configured to generate first chromatic light, a dichroic reflection layer disposed on a light emergent side of the first chromatic light source and allowing the first chromatic light to pass through, and a quantum dot layer. The dichroic reflection layer has a first surface facing away from the first chromatic light source, and the first surface has a plurality of recessed portions. The quantum dot layer includes a plurality of quantum dot blocks, and the quantum dot blocks are disposed corresponding to the recessed portions.

Abstract: A display device is provided. The display device includes a self-emissive layer and a color filter layer. The self-emissive layer includes a plurality of self-emissive units and a plurality of first non-visible light generating units which is respectively disposed among the self-emissive units. The color filter layer is disposed on the self-emissive layer, and includes a shading matrix. The first non-visible light generating units and the shading matrix respectively have a first projection area and a second projection area on a projection plane parallel to the color filter layer. The first projection area and the second projection area at least partially overlap, and the shading matrix at least partially permits the passing through of the first non-visible light generated by the first non-visible light generating units.

Abstract: A display switch method for a portable device and an electronic device which are coupled to each other. In the method, when the portable device is coupled to the electronic device, the portable device stores a current operation status of the portable device according to a display switching signal. According to the hardware parameters of the display of the electronic device, the portable device adjusts a display setting. According to the stored operation status and the display setting, a first operation frame displayed on the portable device is changed to be a second operation frame displayed by a display of the electronic device.
