摘要： A liquid crystal display device includes a display panel with a switchable viewing angle and a driving circuit for driving the display panel. The display panel can switch between wide and narrow viewing angles. The driving circuit includes a display control unit, a viewing angle control unit, a viewing angle control voltage generating circuit, and a gamma voltage generating circuit. The viewing angle control unit is connected to the display control unit, the viewing angle control voltage generating circuit and the gamma voltage generating circuit. The display control unit is used to control the display panel to realize picture display. The viewing angle control unit is used to control the display panel to switch between wide viewing angle display and narrow viewing angle display.
