The present invention provides a method and a device for detecting defects in a pressing test of a touch screen. The method for detecting defects in a pressing test of a touch screen includes: Step S: acquiring, after each test point of the touch screen is tested, an image of a test region in which the test point is located, when performing the pressing test; Step S: identifying a quantity of abnormal points in the acquired image; and Step S: comparing the identified quantity of abnormal points with a quantity of abnormal points allowed in the pressing test, and determining that the touch screen has defects if the identified quantity of abnormal points exceeds the quantity of abnormal points allowed in the pressing test. The above method for detecting defects can check instantly and accurately whether defects arise on the touch screen during the pressing test.

The present invention relates to the field of display techniques, and discloses a light guide plate and a manufacturing method thereof, as well as a backlight module; the light guide plate comprises a light guide plate body and lattice points, wherein the light guide plate body is provided with a light output surface, and a receiving groove for receiving a light source is formed in a surface of the light guide plate body facing away from the light output surface thereof, and a side surface and a bottom surface of the receiving groove form a light input surface. The lattice points are distributed inside the light guide plate body along a plane parallel with the light output surface; the further the lattice points are distanced from the light input surface, the more densely they are distributed. When the above light guide plate is in use, the light source is situated in the receiving groove, and light emitted from the light source is directed into the light guide plate through the side surface and the bottom surface of the receiving groove. Besides, since the further the lattice points are distanced from the light input surface, the more densely they are distributed, the uniformity of light emitted from the light output surface of the light guide plate body can be ensured; in addition, since the lattice points are located inside the light guide plate body, friction is avoided between the lattice points of the light guide plate and the reflecting sheet of the backlight module, which prolongs the life time of the backlight module.

The present invention provides a backlight module and a display device. The backlight module comprises a light source and a backplate comprising a baseplate and a side plate surrounding edges of the baseplate, wherein the light source is provided on the side plate, the baseplate is formed by jointing a plurality of sub-baseplates with different heat conductivities together, and the plurality of sub-baseplates can allow heat generated by the light source to be circulated and led out. In the backlight module provided by the present invention, by jointing a plurality of sub-baseplates with different heat conductivities together to form the baseplate, heat generated by the light source can be circulated and conducted along the sub-baseplates with different heat conductivities, which greatly accelerates heat conduction in the baseplate, may cause the overall temperature of the baseplate to be lowered rapidly and be more uniform, and avoids appearance of wrinkles in film layer with smaller thickness in the backlight module. With the above backlight module, the display device becomes lighter and thinner, and can also ensure good display luminance and display quality.
