Abstract

The invention provides a display device and a backlight module using the same. The backlight module comprises a collimated light source and a light guide plate. The light guide plate is provided witha bottom surface and a top surface which are opposite to each other, and light incident surfaces which are respectively connected to the end parts of the bottom surface and the top surface to receivecollimated light from the collimated light source. The bottom surface inclines from the end portion connected with the light incident surface to the top surface. The bottom surface is provided with aplurality of first grooves which are arranged side by side and extend along the light incident surface. The first groove is provided with a first light receiving surface which is provided with a firstend facing the top surface and obliquely extending away from the light incident surface. Compared with the first light receiving surface closer to the light incident surface, the first end of the first light receiving surface farther away from the light incident surface is closer to the top surface at the vertical projection position of the light incident surface.

Description

technical field [0001] The present invention relates to a backlight module and a display device using the same; specifically, the present invention relates to a backlight module capable of providing collimated backlight and a display device using the same. Background technique [0002] Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and so on. However, with the continuous improvement of specifications such as resolution, narrow bezel, and thinning, the optical design in the display device is also tested. [0003] Taking a liquid crystal display device as an example, its optical performance is usually closely related to the backlight module disposed behind the display panel. In some designs, it is necessary to use a more collimated backlight to cooperate with the front display panel to achieve the expect...
