Abstract: A source driver, a method and a display device are provided. The source driver includes a data receiving circuit, a peak processing circuit, a control circuit, a digital-to-analog conversion circuit, and a driver. The data receiving circuit is configured to receive pixel data and a control timing signal; the peak processing circuit is configured to generate peak over-driving data according to the received pixel data; the control circuit is configured to control to sequentially output the peak over-driving data and the corresponding pixel data to the digital-to-analog conversion circuit according to the received control timing signal; the digital-to-analog conversion circuit is configured to receive the peak over-driving data and the pixel data, convert the peak over-driving data into a first driving signal, and convert the pixel data into a second driving signal; and the driver is configured to output the first driving signal and the second driving signal.

Abstract: A jointing device for metal mask plate welding includes a jointing device body. A height of the jointing device body is smaller than a welding height of a welding gun. The jointing device body has a through-hole corresponding to a welding area of a metal mask. A width of the through-hole is larger than a welding spot diameter of the welding gun. The jointing device body is used for jointing the metal mask to a metal mask receiving frame.
