Abstract: An adaptive magnetic wireless charger comprises a charging dock and a power line. A wireless charging module is arranged in the charging dock, an accommodating cavity is defined around the charging dock by a partition plate, the power line is connected to the wireless charging module, a holding plate is disposed in the accommodating cavity, a magnetic and a spring are mounted on the holding plate, and one end of the spring abuts against an inner top surface of the charging dock.

Abstract: An electronic device protective case for wireless charging comprises a shell used for clamping an electronic device. A magnetism-isolation sheet is laid on the inner bottom surface of the shell, A hollowed-out part matched with a wireless charging coil is formed in the magnetism-isolation sheet. A mismatched electromagnetic field is shielded by means of the magnetism-isolation sheet to avoid an influence on metal in the electronic device, so that the situation that the metal becomes hot under the effect of the magnetic field is avoided, damage to components and welding spots on a circuit board is also avoided, and thus, metal parts in the mobile phone or the tablet computer will not be affected no matter whether or not the protective case matches the mobile phone or the tablet computer in position; and meanwhile, diffusion of the electromagnetic field is reduced, and charging efficiency is effectively improved.

Abstract: The present application describes a plasma display panel structure with high contrast ratio and high luminance. In one embodiment, display cells in the plasma display panel are arranged in a delta structure. The delta structure of display cells enhances the luminance and contrast ratio of the plasma display panel. In some embodiments, a light-shielding layer is configured to selectively exclude display cells of one or more selected colors to enhance the color temperature of the plasma display panel.

Abstract: An alternating current drive type plasma display panel (AC PDP) having a discharge cell-defining barrier structure with minimized firing shrinkage distortions provided by selecting different line widths for the barrier rib row and column members, and/or adding supplementary barrier rib members adjacent the peripheral edges of the barrier rib structure, and/or reducing the zig-zag distances of the edge profile of the barrier rib structure.
