Demultiplexer and display device

A display device, wherein the display device includes a demultiplexer applied in a display panel, the demultiplexer is connected with a scanning driving circuit, and the scanning driving circuit comprises multiple scanning driving units connected sequentially, wherein, the demultiplexer comprises:

• a data signal terminal for outputting a data signal;
• a control signal unit for outputting a first group of control signals and a second group of control signals;
• a switching unit connected with the data signal terminal and the control signal unit, and the switching unit includes a first switching group and a second switching group;
• and
• a pixel unit connected with the first switching group and the second switching group;
• wherein, when odd rows of the scanning driving units of the scanning driving circuit output scanning signals, the first group of control signals controls the first switching group to be turned on, and the second group of control signals controls the second switching group to be turned off such that the data signal outputted by the data signal terminal charges the pixel unit connected with the odd rows of the scanning driving units of the scanning driving circuit through the first switching group;
• and
• when even rows of scanning driving units of the scanning driving circuit output scanning signals, the second group of control signals controls the second switching group to be turned on, and the first group of control signals controls the first switching group to be turned off such that the data signal outputted by the data signal terminal charges the pixel unit connected with the even rows of the scanning driving unit of the scanning driving circuit through the second switching group such that a refresh rate of the first group of control signals and the second group of control signals are decreased.
