A liquid crystal driving circuit (340), a backlight lamp circuit, a terminal, a device, and a method, related to the technical field of displays. In an open-window display mode, the output start position and number of outputs of a scan voltage are controlled by a scan driver chip (2), data line switches (4) corresponding to data lines (31) not intersecting an open window area are set to a disconnected state; a display content corresponding to the size of the open window area is generated, grayscale voltages corresponding to the display content are transmitted to data lines (31) intersecting the open window area via a data driver chip (3); and backlight lamps having lighting positions intersecting the open window area are controlled by a backlight circuit (710) into emitting a light. This solves the problem of power wastage caused by the data lines (31), scan lines (21), and backlight lamps not in the open windows area being in an operating state in the open window display mode. This achieves the effect of reduced power consumption by having only the data lines (31), scan lines (21), and backlight lamps corresponding to the open window area in operating state in the open window display mode. |
