The long axis direction of the electrified liquid crystal is parallel to the direction of the electric field, the refractive index of the cylindrical lens is not matched with that of the liquid crystal, light enters left and right eyes of a person respectively after refraction, and a 3D image is formed after brain integration, and the mode is a 3D mode.
In the process of switching between the 2D and 3D modes, the alignment of the liquid crystal in the designated direction requires a certain response and flip time, similar to the response time of an LCD display. For the switchable naked eye 3D display, the switching time between the two is a very important index, and the shorter the time, the better the user experience. Therefore, we need to measure and optimize the switching time accurately during the production process.

Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As described in the background art, in the prior art, the switching time between the 2D mode and the 3D mode cannot be obtained, and in order to solve the above technical problems, the present application provides a method and a system for detecting the switching time between the 2D mode and the 3D mode.
In an exemplary embodiment of the present application, as shown in fig. 1, a method for detecting a switching time between a 2D mode and a 3D mode is provided, where the method includes: step S1, acquiring the maximum haze value and the minimum haze value of the 3D display device in the power-on and/or power-off process, wherein the minimum haze value in the power-on process is T1, the maximum haze value in the power-on process is T2, the maximum haze value in the power-off process is T3, and the minimum haze value in the power-off process is T4; step S2, obtaining Δ T1 by subtracting T2 from T1, and/or obtaining Δ T2 by subtracting T4 from T3, and further obtaining at least one switching time between 2D mode and 3D mode, where Δ T1>0 and Δ T2> 0.
The applicant finds that the 2D mode and the 3D mode of the 3D display device respectively correspond to the minimum haze value and the maximum haze value of the display screen, because the refractive index of the electro-optic material (generally, liquid crystal) in the 3D display device is the same as that of the view separation structure layer in the 2D mode, and at this time, light can directly pass through the display device, so the haze value of the display screen corresponding to the 2D mode is minimum, and the refractive index of the electro-optic material in the 3D display device is different from that of the view separation structure layer in the 3D mode, and at this time, the light is refracted and scattered, and cannot directly pass through the display device, so the haze value of the display screen corresponding to the 3D mode is maximum.
Therefore, by testing the haze of the display screen in the switching process of the 3D display device between the 2D mode and the 3D mode, namely in the power-on or and/or power-off process, the maximum haze value and the minimum haze value in the power-on or power-off process can be obtained, and then the time point corresponding to the maximum haze value and the minimum haze value in a maximum value pair is found, the maximum haze value and the minimum haze value form a time pair, the time maximum value and the minimum value in the same time pair are subjected to difference, the switching time of the 2D mode and the 3D mode is obtained through calculation, and then the user experience effect can be optimized according to the switching time.
Note that since Δ T1>0 in the present application, "difference between T2 and T1" in the present application does not limit the order of specific decrements and decrements, and is smaller than the larger of T1 and T2; also, since Δ T2>0 in the present application, "differencing T4 and T3" in the present application does not limit the order of specific decrements and decrements, but all subtract smaller from the larger of T3 and T4.

For the 3D display device, when the power is on, the 3D display device is switched from the 2D mode to the 3D mode, the minimum haze value appears first, and the maximum haze value appears later, namely T2> T1; when the power is off, the 3D mode is switched to the 2D mode, the maximum haze value appears first, and the minimum haze value appears later, namely T4> T3. Therefore, for such a 3D display device, the above step S2 of acquiring the switching time includes: subtracting the smaller T1 from the larger T2 to obtain a switching time Δ T1 for switching the 2D mode to the 3D mode of the 3D display device, wherein the switching time Δ T1 is obtained by taking the difference between the T2 and the T1; the difference between T4 and T3 is obtained by subtracting a smaller T3 from a larger T4, thereby obtaining a switching time Δ T2 for switching the 3D mode of the 3D display device to the 2D mode.
In another embodiment of the present application, as shown in fig. 3, the view separating element 20 in the above-mentioned 3D display device includes a lenticular lens layer 21, and the lenticular lens layer includes a plurality of concave lenses arranged in sequence, that is, a plano-concave lens layer, the plano-concave lens layer is disposed on the first substrate 10, and the electro-optical material 30 is disposed on a surface of the plano-concave lens layer away from the first substrate 10, that is, between the second substrate 40 and the plano-concave lens layer. For the 3D display device, when the power is on, the 3D display device is switched from the 3D mode to the 2D mode, the maximum haze value appears first, and the minimum haze value appears later, namely T1> T2; when the power is off, the 2D mode is switched to the 3D mode, the minimum haze value appears first, and the maximum haze value appears later, namely T3> T4. Therefore, for such a 3D display device, the above step S2 of acquiring the switching time includes: subtracting the smaller T2 from the larger T1 to obtain a switching time Δ T1 for switching the 3D mode of the 3D display device to the 2D mode, wherein the difference is obtained between the T2 and the T1; the difference between T4 and T3 is obtained by subtracting a smaller T4 from a larger T3, thereby obtaining a switching time Δ T2 for switching the 2D mode to the 3D mode of the 3D display device.
