Abstract: Proposed is a technology related to a compensation method for excess loop delay (ELD) using a time division switching (TDS) technique. A delta-sigma modulator (DSM) to which the compensation method for excess loop delay is applied includes a single op-amp resonator (SOR) loop filter.

For at least two of the plurality of resistor units, a resistance value of each of the at least two resistor units is changed according to a clock signal, and a coefficient of a third-order transfer function of the loop filter is changed according to the clock signal, thereby effectively compensating for excess loop delay of the delta-sigma modulator.

Abstract: Present disclosure discloses a dense-viewpoint three-dimensional display system and display method thereof, which uses the smallest surface structure that can emit light independently as a display cell. A light-guiding element of an eyebox-generating device guides beams from corresponding display cells to discretely arranged eyeboxes with dense viewpoints. In present disclosure, a display cell projects a beam along a special projecting path to the corresponding viewpoint. Relative to traditional 3D display which takes a pixel as a display unit and lets all sub-pixels of a pixel correspond to a common projecting path, present disclosure can effectively increase the reachable viewpoint number. Furthermore, configuring discretely distributed eyeboxes to keep tracking a viewer's pupils also can reduce necessary viewpoint number for implementing a VAC-free 3D display.

Abstract: The present invention relates to a method for crystallization of a metal oxide thin film by using thermal dissipation annealing (TDA) and exhibits an effect enabling high-temperature thermal annealing, which is essential for the performance improvement of a semiconductor material, a sensor material, and the like deposited on a thin-plate substrate, even without degrading the performance of the thin-plate substrate. In addition, a metal oxide thin film prepared by the method of the present invention is in the form of a two-dimensional nanosheet, and thus may have a low defect density (high crystallinity) and a wide surface area. Accordingly, based on the improved photosensitivity and photoreactivity, the metal oxide thin film may be utilized in a high-performance photoelectric device.

Abstract: Quantitative phase imaging (QPI) is a label-free computational imaging technique that provides optical path length information of objects. Here, a diffractive QPI network architecture is disclosed that can synthesize the quantitative phase image of an object by converting the input phase information of a scene or object(s) into intensity variations at the output plane.
