Abstract: A method and a device for a picture detection, a display panel and a computer-readable storage medium. The method includes steps of: obtaining a grayscale value of each sub-pixel in each minimum detection unit respectively; and exiting a picture detection function if at least one of the x minimum detection units meets a first preset condition corresponding to the at least one of the x minimum detection units when the picture detection function for a preset detection area is in an enabled state. A first preset condition corresponding to a first minimum detection unit is that the grayscale value of at least one sub-pixel of a first type is smaller than or equal to a first value, or alternatively, the grayscale value of at least one sub-pixel of a second type is greater than or equal to a second value.

Abstract: Related to the field of display panels, an array substrate, a manufacturing method thereof, and a display panel. The array substrate includes: the base substrate, the buffer layer, the active layer, the gate insulation layer, the gate, the interlayer insulation layer, the source, and the drain, which are stacked together. By using the gate insulation layer as a conductive mask of the active layer, and by adjusting the width of the gate and the width of the gate insulation layer, a width difference between the channel region and the gate is within the preset range, which reduces the problem of excessive width difference caused by the diffusion phenomenon of the channel region, and can at the same time meet the switching characteristics requirements of the thin film transistor and the definition requirements of the display panel.
