Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.

Abstract: A calibrating device includes a memory and a processor. The memory is configured to store at least one computer readable instruction. The processor is electrically coupled to the memory, and configured to access and execute the at least one computer readable instruction to: analyze an image of a target region which a seam between two LED panels disposed side by side is in, to obtain characteristic data associated with the seam; compare the characteristic data associated with the seam with a predetermined value to generate a comparison result; and adjust grayscale data of pixels which are arranged in two lines of the two LED panels and adjacent to the seam, based on the comparison result, for adjusting luminance-chromaticity of the pixels, wherein the two lines are in a first direction or a second direction, and the first direction is perpendicular to the second direction.

Abstract: A method and an image processing device for mura detection on a display are proposed. The method includes the following steps. An original image of the display is received and segmented into region of interest (ROI) patches. A predetermined range of spatial frequency components are filtered out from the ROI patches to generate filtered ROI patches. A mura defect is identified from the display according to the filtered ROI patches and predetermined mura patterns.

Abstract: An optical element configured to allow an image beam passing through is provided. The optical element includes a first and a second birefringent layer and a gas layer between the first and the second birefringent layer. An extension direction of the gas layer is inclined with respect to an extension direction of the optical element, wherein the image beam passes through the first birefringent layer, the gas layer and the second birefringent layer in sequence. A first and a second sub image beam having different deflection angles are generated from the image beam when the image beam enters the gas layer. After the first and the second sub image beam are emitted from the second birefringent layer, a transmission path of the first and the second sub image beam are offset from each other by an offset distance, thereby improving resolution of an image to be viewed.
