A control method of a display includes a statistics circuit, a backlight determining circuit and a backlight control circuit. The display includes a backlight module having a maximum luminance. The statistics module receives frame, and generates luminance statistical information of a plurality of blocks included in the frame. The backlight determining circuit determines a backlight intensity corresponding to each of the blocks according to the luminance statistical information of the blocks and the maximum luminance. At least one of the backlight intensities corresponding to the blocks is greater than a normal luminance, which is a backlight intensity corresponding to one of the blocks when a maximum power is evenly distributed on light emitting elements of the display. The backlight control circuit controls the luminance of the backlight module according to the backlight intensities.

Backlight control and image compensation method applied to display and associated control method

A fabricating method of a device substrate including the following procedures is provided. First, a substrate is provided and a patterned structure is formed on the substrate, wherein the patterned structure includes a plurality of openings. Then, a protective layer is formed on the patterned structure, wherein the protective layer does not fully fill the openings of the patterned structure such that a gap is existed between the protective layer and the patterned structure. Later, a device layer is formed on the protective layer.
