Problems solved by technology

[0004] The known paired stereoscopic image imaging technology adopts a spatial-multiplexed method (spatial-multiplexed method, such as lenticular screen and parallelax barrier), that is, the pixels of the liquid crystal layer are divided into multiple stereoscopic imaging pairs, and the images of the left and right eyes are respectively projected to the left and right eyes to form a stereoscopic image; however, the spatial multitasking method has the disadvantages of halving the resolution and brightness, and has alignment problems. In addition, the system is bulky, which is not conducive to production

[0083] Figure 4 It is a schematic diagram of the second embodiment of the stereoscopic imaging device of the present invention. The difference between the stereoscopic imaging device 1' of this embodiment and the stereoscopic imaging device 1 of the first embodiment lies in: the first guide of this embodiment The first micro-groove structure surface 11a' of the light plate 11' faces the second micro-groove structure surface 13a' of the second light guide plate 13', and in the backlight assembly 10' of this embodiment, a third The reflective plate 17' replaces the absorbing plate 17, wherein the third reflective plate 17' is disposed under the first light guide plate 11' to reflect the light emitted from the bottom surface of the first light guide plate 11' back to the first light guide plate 11' .

[0084] Compare Figure 4 and figure 1 It can be known that, in this embodiment, the traveling direction of the light L4 emitted from the second light source 14 ′ is the same as...

Abstract

It is an aphototropism element and the space image-forming device and method by use of it, wherein the aphototropism element comprises one first light conductive plate, one first light source, one second light conductive plate and one second light source. The first light conductive plate has one first micro-groove structure surface, one first side, and one-second side against to the first side. The fist light source is set on the first side of the light conductive plate and the second one is set on the first light conductive plate and comprises one-second micro groove structure surface, one third side and fourth side against to the third one. The second light source is set on the fourth side of the second light conductive plate.

Description

technical field [0001] The invention relates to a backlight assembly, in particular to a backlight assembly applicable to a stereoscopic image imaging device. Background technique [0002] The principle of artificial stereoscopic image imaging is to simulate the real situation, produce real three-dimensional objects, or project different images (paired stereoscopic images, stereo pairs) to the left and right eyes, and provide additional depth information to form a stereoscopic image. [0003] The known stereoscopic imaging techniques can be divided into three types: holographic, multi-plane and paired stereoscopic. Due to the difficulties in processing a large amount of data and the disadvantages of poor display effects in the holographic and multi-plane displays, the research on stereoscopic image displays in recent years has focused on paired stereoscopic images. [0004] The known paired stereoscopic image imaging technology adopts a spatial-multiplexed method (spatial-m...
