The invention provides a light guide plate, a back light source and a display. The back light source comprises at least two light source groups, wherein each light source group comprises a luminous light source and a light guide plate, each light guide plate is used for guiding light sent out by the luminous light source and comprises a first side surface, and a first reflecting sheet used for reflecting the light sent out by the luminous light source to the inside of the light guide plate in the first direction is arranged on each first side surface. A plurality of stripped light guide plates form the back light source through parallel permutation and combination, the reflecting sheet is pasted on each light guide plate, in addition, light guide points are formed, the uniform spreading of the light sent out by the luminous light source in the corresponding light guide plate can be ensured, the light cannot be scattered into the peripheral light guide plates, the line-by-line scanning technology of the back light source can be preferably realized, and the problems of complicated manufacture process of the light guide plate and insufficient light spreading and scattering uniformity in the prior art can be solved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight source and a display. Background technique [0002] In liquid crystal display technology, the shutter type is one of the methods to realize 3D display. The shutter-type 3D display technology is to refresh the LCD screen at a fast display frequency (at least 120HZ), and at the same time use 3D glasses to ensure a fast refresh of 60Hz for the left eye and right eye, so that the audience's two eyes will see fast switching Different pictures of different images, and create an illusion in the brain, and then watch the three-dimensional image. [0003] At present, 3D display technology often uses the backlight screen to scan area by area at the same time, that is, when the screen outputs the left-eye signal, the backlight in the left-eye signal area is basically controlled to emit light, and the backlight area of the right-eye signal screen remains unillum...
