Pixel array substrate and display device

A display device, comprising a pixel array substrate and a display medium disposed on the pixel array substrate, wherein the pixel array substrate comprises:

• a substrate;
• a plurality of first scan lines;
• a plurality of second scan lines, wherein the first scan lines and the second scan lines are disposed alternately and enabled for different time durations in the same frame time;
• a plurality of data lines, intersecting with the first scan lines and the second scan lines;
• and
• a plurality of pixel structures, disposed on the substrate and arranged in an array, each of the pixel structures comprising:
• a first active device, controlled by the one of corresponding first scan lines;
• a second active device, controlled by the one of corresponding second scan lines;
• a pixel electrode, connected to the second active device, and the first active device being connected to the one of data lines;
• and
• a gate drive circuit disposed on the substrate and comprising a plurality of gate block signal lines and a plurality of gate selection signal lines,
• wherein a distance between the first scan line and the second scan line adjacent to each other is a third to a half of a pitch of the pixel structures, N consecutive first scan lines are classified as a first scan line group, each of the first scan line groups is connected to an identical one gate block signal line, N consecutive second scan lines are connected to N gate selection signal lines sequentially, N is a positive integer, and the N gate selection signal lines are enabled sequentially within a time duration of each of the gate block signal lines being enabled.
