Abstract: The present disclosure provides a backlight source flatness detection system and a backlight source flatness detection method. The backlight source flatness detection system includes: a working table, a support column, a detection device, a processor and a display device. The working table is transparent and carries a to-be-detected backlight source. The support column supports the working table. The detection device is below the working table and detects distances between the detection device and at least two detection positions of the to-be-detected backlight source. The at least two detection positions includes at least one position of a center area and at least one position of a peripheral area. The processor is connected to the detection device and processes a detection result from the detection device so as to acquire a warpage value. The display device is connected to the processor and to display the warpage value acquired by the processor.

Abstract: A fabricating method of grid points on light guiding plate, a fabricating method of light guiding plate, and a backlight module comprising the light guiding plate fabricated by the fabricating method of light guiding plate and a display device. The fabricating method of grid points on a light guiding plate comprises following steps of: forming a layer of photosensitive material on a mold for the light guiding plate (S1); and performing photolithography on the photosensitive material in order to form grid points on the light guiding plate (S2). Since the mold for the light guiding plate is not etched directly, the grid points on the light guiding plate can be made without damaging the surface of the mold for the light guiding plate, and the cost for polishing the mold surface is saved and the overall process is simplified.
