摘要： An electric power assist device and a driving method for an electric vehicle are provided. The electric power assist device adapted for the electric vehicle includes an angle sensing unit, a driving module, and a control module. The angle sensing unit senses a tilting angle of the electric vehicle on the road. The driving module includes a power driving unit and a motor. The driving module receives a control signal for driving the electric vehicle by the motor. The control module is coupled to the angle sensing unit and the driving module. The control module adjusts the control signal according to a change of the tilting angle to increase a torque force of the motor when the electric vehicle is on an uphill road.

摘要： A backlight module includes a light guide plate (LGP), a light source, and at least one prism sheet. The LGP includes a light emitting surface, a bottom surface, a light incident surface, and a plurality of first microstructures on the bottom surface. Each of the first microstructure is a recessed structure and includes a first surface and a second surface. An included angle between the first surface and the bottom surface ranges from 15 degrees to 27 degrees. An included angle between the second surface and the bottom surface ranges from 50 degrees to 90 degrees. The light source provides a light beam, and an included angle between a light emitting direction of the light beam emitted from the light emitting surface of the LGP and a normal direction of the light emitting surface is greater than 30 degrees. The prism sheet is disposed above the light emitting surface.
