Detecting device of 2D/3D switchable scene separation element

Abstract

The invention discloses a detecting device of a 2D / 3D switchable scene separation element. The detecting device comprises a light source module, a polarizing module and a detecting module. The light source module comprises at least one laser emission unit. The polarizing module is used for receiving a laser beam and converting the laser beam into a polarized beam. The detecting module comprises aprocessing unit and at least one detecting unit. The detecting units are used for receiving refracted beams passing through the 2D / 3D switchable scene separation element and for detecting light intensity of the refracted beams at different times. The processing unit is connected with the detecting units and is used for receiving light intensity of the refracted beams at different times and for determining the switching time of the 2D / 3D switchable scene separation element switching between a 2D mode and a 3D mode according to the corresponding time when the refracted beams are at the first preset light intensity and the corresponding time when the refracted beams are at the second preset light intensity. The detecting device of the 2D / 3D switchable scene separation element solves the problems of low efficiency and low accuracy of manual switching time detection.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of 3D display, and in particular to a detection device for a 2D / 3D switchable view separation element. Background technique [0002] With the development of stereoscopic display technology, 2D / 3D switchable products with both 2D and 3D display functions have emerged at the historic moment. Compared with pure 2D display devices or 3D display devices, products with both 2D and 3D displays are more likely to be attracted by users. of favor. [0003] For switchable 2D / 3D products, in practical applications, mutual switching between 2D mode and 3D mode is often involved. Generally speaking, when switching between the 2D mode and the 3D mode, the shorter the switching time, the better the user experience. Therefore, detecting the time it takes for the 3D product to switch between the 2D mode and the 3D mode is an important index for testing the quality of the 3D product. [0004] In the pr...

Problems solved by technology

However, on the one hand, the efficiency of manual observation is low, time-consuming and labor-intensive, and the cost is high, which is not conducive to the mass production of 3D products

On the other hand, limited by the structure of the human eye, the accuracy of manual observation is low, and it is impossible to accurately record the switching time of 3D products, and it is also impossible to directly judge whether the mode switching of 3D products is complete.
