Array substrate, display panel and display device

A display panel, comprising an array substrate, wherein the array substrate comprises:

• a base substrate, wherein the base substrate comprises a display region and a non-display region which surrounds the display region, and the base substrate further comprises a first side extending in a first direction and a second side extending in a second direction, and the first direction and the second direction are intersected with each other;
• at least one pressure sensor is disposed in the non-display region of the base substrate;
• wherein the at least one pressure sensor comprises a first resistor, a second resistor, a third resistor and a fourth resistor, and a bridge structure is formed by the first resistor, the second resistor, the third resistor and the fourth resistor;
• wherein
• the non-display region of the based substrate further comprises a plurality of shift registers successively arranged along the second direction, a length of each of the plurality of shift registers in the first direction is greater than a length of each of the plurality of shift registers in the second direction, and the first resistor, the second resistor, the third resistor and the fourth resistor are disposed at least one of following positions:
• inside the shift register, between adjacent two of the plurality of shift registers, at a side of the plurality of shift registers close to the display region, and at a side of the plurality of shift registers away from the display region;
• and
• wherein when one of the first resistor, the second resistor, the third resistor, and the fourth resistor is disposed between adjacent two of the shift registers, an extension length of the resistor disposed between the adjacent two of the shift registers along the first direction is greater than that along the second direction;
• and
• wherein when one of the first resistor, the second resistor, the third resistor, and the fourth resistor is disposed at a side of the display region closer to the plurality of shift registers, an extension length of the resistor disposed at the side of the display region closer to the plurality of shift registers along the second direction is greater than that along the first direction.
