Abstract: An in-cell capacitive touch screen and a display device using the same are provided. The touch screen includes an array substrate having a common electrode layer, a color-filter substrate having an array of filter cells, and a liquid crystal layer. The array substrate may include a pixel cell array corresponding to the array of filter cells of the color-filter substrate. The common electrode layer may include a plurality of driving electrodes extending along a row direction of the pixel cell array. The color-filter substrate may further include a black matrix to interval filter cells in the array of filter cells. The color-filter substrate may further include a plurality of sensing electrodes extending along a column direction of the pixel cell array. The projection of the sensing electrodes on the color-filter substrate overlaps the corresponding columns of the black matrix.

Abstract: An anti-collision device for a plasma vertical cutting gun including a lifting frame of a plasma cutting machine; a connection mechanism; a fixing plate of a cutting gun fixed on the connection mechanism; a concave support plate connected with the lifting frame of the plasma cutting machine; and a proximity switch mounted on the concave support plate. The connection mechanism is mounted between the lifting frame of the plasma cutting machine and the fixing plate of the cutting gun. A contact surface between the connection mechanism and the concave support plate matches. One side of a joint plane between the connection mechanism and the concave support plate is of ferromagnetic materials and the other side is provided with a magnet, thereby attracting each other to realize a magnetic connection. The anti-collision device has comprehensive functions, convenient installation, reasonable structure, and short response time in case of impact.
