[0057] The aforementioned and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with accompanying drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only referring to the directions of the drawings. Accordingly, the directional terms are used to illustrate and not to limit the invention.

[0058] figure 1 is a schematic cross-sectional view of the display device according to the first embodiment of the present invention. Please refer to figure 1 , the display device 1000 of this embodiment may include a backlight module 100 and a display panel 200 . The backlight module 100 of this embodiment includes a light emitting unit 110 and a light control element 120 . The light emitting unit 110 is used for providing a pair of parallax light beams L, wherein the light emitting unit 110 has a ligh...

[0088] Figure 6 It is a schematic cross-sectional view of a display device 2000 according to the second embodiment of the present invention. Please refer to Figure 6 The display device 2000 of this embodiment is similar to the display device 1000 of the first embodiment, and the functions it can achieve are also similar to those of the display device 2000 of the first embodiment. However, in this embodiment, the arrangement of the light control element 120 is different from that of the first embodiment, and only this part will be described in detail below, and the similarities will not be repeated.

[0089] In this embodiment, the first plane 122c of each light control unit 122 of the light control element 120 faces away from the light emitting unit 110 . In this way, the light beam L1 emitted by the first light emitting element 112 will be split into three light beams L1-a, L1-b, L1- c, the light rays L1-a, L1-b, L1-c will carry the right eye image after passing through ...

Abstract

The invention discloses a backlight module including a light emitting unit and a light controlling element. The light emitting unit is capable of providing a pair of parallactic light beams, wherein the light emitting unit has a light emitting surface. The light controlling element includes a plurality of light controlling units. Each of the light controlling units has a first inclined surface, a second inclined surface, and a first plane. The first inclined surface is inclined with respect to the light emitting surface. The second inclined surface is inclined with respect to the light emitting surface, wherein the inclined direction of the second inclined surface is opposite to the inclined direction of the first inclined surface. The first inclined surface, the second inclined surface, and the first plane are capable of dividing the pair of the parallactic light beams into a plurality of pairs of sub-parallactic light beams. A display apparatus is also provided.

Description

technical field [0001] The invention relates to a backlight module and a display device, and in particular to a backlight module and a display device for displaying stereo images. Background technique [0002] With the advancement of display technology, displays with good picture quality, rich colors and good effects are constantly being introduced. In recent years, stereoscopic display technology has a tendency to be extended from movie theaters to home displays. Since the key of the stereoscopic display technology is to let the left eye and the right eye see the left-eye picture and the right-eye picture with different viewing angles respectively, the stereoscopic display technology in the prior art mostly adopts the method of letting the user wear special glasses to screen the left and right eyes. Eye frame and right eye frame. [0003] However, it usually causes a lot of inconvenience for users to wear special glasses, especially for users who are nearsighted or farsig...
