In other instances, well-known steps or operations are not described in detail to avoid obscuring the invention.

Example one

The invention provides a method for playing a film on an automobile, which can be applied to the automobile, wherein the whole automobile glass of the automobile is attached to a PDLC dimming film, and as shown in figure 1, the method can comprise the following steps:

in step S21, a first dimming control signal is generated when the vehicle state of the automobile is determined to meet a preset condition.

Specifically, in the present solution, a vehicle control unit of the vehicle may be used as an execution main body of the method of the present solution, where the vehicle control unit is used to control each hardware device of the vehicle. The user may send a viewing instruction for the vehicle, for example, when the user wants to watch a movie in the vehicle, the user may operate the central control panel to input the viewing instruction, that is, the user inputs a signal requesting to open a theater function to the vehicle, the vehicle controller determines a current vehicle state, and when the vehicle state of the vehicle is determined to meet a preset condition, the vehicle controller generates a first dimming control signal, and it needs to be noted that the first dimming control signal is used for controlling light in the vehicle. It should be noted that the preset condition may be that the vehicle state of the automobile satisfies a safe state. Such as the vehicle being stationary, etc.

The movie may be any image with a screen.

And step S23, sending the first dimming control signal to a relay of the PDLC dimming film of the automobile, wherein the relay of the PDLC dimming film of the automobile executes the first dimming control signal, so that the PDLC dimming film is converted from an initial state to a target state.

Specifically, in this scheme, the vehicle control unit can be connected with the relay of the PDLC dimming film, and after the vehicle control unit generates the first dimming control signal, the vehicle control unit can send the first dimming control signal to the relay of the PDLC dimming film, and the relay of the PDLC dimming film executes the first dimming control signal, so that the PDLC dimming film is converted from the initial state to the target state. The initial state may be that the PDLC dimming film is transparent, and the target state may be that the PDLC dimming film is opaque. It should be noted that, referring to fig. 2, when the PDLC dimming film relay is powered on, the PDLC dimming film is under the action of the electric field, and the polymer liquid crystal material in the middle of the film is orderly arranged, so that the light outside the automobile can penetrate through the film, and the effect is seen as a transparent and colorless film, and the light inside the automobile can be bright. When the light adjusting film is powered off, the polymer liquid crystal materials in the light adjusting film are arranged in disorder, so that light cannot penetrate through the film, the light is in a milky opaque state when the light adjusting film is seen, and the light in an automobile can be dim. It should be noted that, under dim light, a comfortable atmosphere for the automobile user to see the fixation can be created, which increases the user experience.

The PDLC is a Polymer Dispersed Liquid Crystal, which is generally called Polymer Dispersed Liquid Crystal, and the PDLC dimming film is a mature technical product at present, and the PDLC is a material obtained by mixing a low-molecular Liquid Crystal with a prepolymer, performing a polymerization reaction under a certain condition to form micron-sized Liquid Crystal droplets, uniformly dispersing the micron-sized Liquid Crystal droplets in a Polymer network, and then utilizing dielectric anisotropy of Liquid Crystal molecules to obtain a material with an electro-optic response characteristic. The PDLC light modulation film is a film capable of adjusting the light passing state, and mainly works between a scattering state and a transparent state, namely the film can be changed between the transparent state and the non-transparent state, and the transparency of the film is adjusted by voltage.
