Array substrate, display panel and display device

A display panel, wherein the display panel includes an array substrate, and the array substrate comprises multiple scanning lines, multiple data lines, multiple shift registers and multiple switching units;

• wherein the multiple scanning lines and the multiple data lines are intersected in order to form multiple pixel units;
• wherein each shift register is used for inputting a scanning signal to one terminal of a corresponding scanning line, the other terminal of each scanning line is connected with a first terminal of the switching unit, a second terminal of the switching unit receives a first reference voltage, a control terminal of the switching unit receives a first control signal;
• and wherein the shift register and the switching unit simultaneously pull down a voltage level of the scanning line to a low level;
• wherein the multiple shift registers includes multiple odd-numbered stage of the shift registers and multiple even-numbered stage of the shift registers, the multiple odd-numbered stage of the shift registers are disposed at a left side of a display region of the array substrate, the multiple even-numbered stage of the shift registers are disposed at a right side of the display region of the array substrate, the multiple odd-numbered stage of the shift registers are respectively connected with terminals of odd-numbered stage of the scanning lines, and the multiple even-numbered stage of the shift registers are respectively connected with terminals of even-numbered stage of the scanning lines;
• wherein the multiple switching units include multiple first switching units and multiple second switching units, the multiple first switching units are disposed at the right side of the display region, and the multiple second switching units are disposed at the left side of the display region;
• wherein the multiple first switching units are respectively connected with the other terminals of the odd-numbered stage of the scanning lines, and the multiple second switching units are respectively connected with the other terminals of the even-numbered stage of the scanning lines;
• and
• wherein the multiple shift registers are disposed at the left side of the display region of the array substrate, the multiple switching units are disposed at the right side of the display region.
