Abstract
The invention discloses a light guide plate, a backlight module group, and a display. The light guide plate comprises a light outgoing surface, a reflecting surface, and a side surface which surrounds the light outgoing surface and the reflecting surface, wherein the light outgoing surface and the reflecting surface are arranged to be opposite to each other. The reflecting surface is provided with a reflector, and the reflector comprises a convex block and an annular groove, wherein the convex block is bulged from the reflecting surface, and the annular groove is arranged around the convex block, and is recessed towards the interior of the light guide plate from the reflecting surface. The convex block is shaped like a spherical crown, and a concave surface of the annular groove is provided with a plurality of scattered network sites which are bulged from the convex surface. According to the technical scheme, the light guide plate will carry out the repeated reflection, diffraction and total reflection when the light entering the light guide plate runs into the above reflector, then enables the light to go out from the light outgoing surface through the repeated use of a reflecting sheet disposed at one side of the reflecting surface, and enables the light energy to be used completely, so as to achieve the optimal effect and improve the market competiveness.
Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a light guide plate, a backlight module and a display. Background technique [0002] With the development of the economy and the improvement of people's living standards, various electrical products (such as TVs, computers, etc.) have been integrated into our lives, and the display on the electrical product is the key to the size, performance and user experience of the electrical product Factors, the display has become the focus of attention of users when choosing electrical products. Among them, LED displays have advantages in thickness, picture quality, lifespan, energy saving and environmental protection, and have gradually replaced traditional CCFL backlight displays. With increasingly fierce market competition, LED display thinning products are the main competitive technology point. [0003] Among them, the backlight module is a key component in the display. The backlig...
