3D and 2D compatible receiving apparatus of adjustable shutter type 3D glasses, and method thereof

Abstract

The invention discloses a 3D and 2D compatible receiving apparatus of adjustable shutter type 3D glasses, and a method thereof. The 3D and 2D compatible receiving apparatus comprises: a signal receiving module, a signal processing module, an adjusting receiving mode module, a left shutter control module, a right shutter control module, a left shutter, a right shutter and a receiving mode state display. Input terminals of the signal processing module are respectively connected with the signal receiving module and the adjusting receiving mode module. Output terminals of the signal processing module are respectively connected with the input terminals of the left shutter control module and the right shutter control module. The output terminals of the left shutter control module and the right shutter control module are respectively connected with the left shutter and the right shutter. The signal processing module is also connected with the receiving mode state display. By adopting a technology scheme of the invention, compatible receiving of 3D and 2D frames can be reached through changing the receiving apparatus, and control of external display equipment does not need to be changed. Meanwhile, the 3D and 2D frames can be respectively and simultaneously watched by different users under a same screen through adjusting the receiving mode of the receiving apparatus by the users.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a receiving device and method compatible with 3D and 2D of adjustable shutter type 3D glasses. Background technique [0002] At present, 3D display technology can be divided into two categories: glasses type and naked eye type. For the current civilian market, due to technical limitations and cost considerations, the glasses type is more popular, and the naked eye type is rarely listed. Glasses-type 3D display technology mainly includes three types: chromatic aberration type, polarized light type, and active shutter type, which are commonly referred to as color separation, light separation, and time division methods. Widely adopted by display device manufacturers. [0003] In the 3D display technology that is popularized in the family, the active shutter display principle is: the external display device first displays the picture for the left eye, then the 3D glasses will si...

Problems solved by technology

[0004] Therefore, when the user selects the 3D mode, the user can watch the 3D images by wearing special 3D glasses, but in the 3D mode, if the user directly watches the display screen with naked eyes, the images sent by the display screen are different for the left and right eyes. , so that users can only see blurry images with ghosting, that is, when some users wear 3D glasses and watch in 3D display mode, other users cannot directly watch clear screen images with naked eyes, nor can they use glasses to watch 2D images

In addition, due to the limitations of the current 3D display technology, watching 3D images for a long time will easily cause users to feel uncomfortable. If the user exits the 3D display mode and chooses the 2D display mode at this time, it will definitely affect other viewers who are watching the 3D display mode at the same time.

All in all, the current 3D display and receiving devices cannot realize simultaneous viewing of 3D and 2D display images
