The invention provides a car roof display device and a control method thereof. In the car roof display device, a controlled end of a conductive glass skylight is connected with an output end of an electronic control unit, and the conductive glass skylight is opened or closed under the control of the electronic control unit; the conductive glass skylight is in a transparent state when being opened and is in a non-transparent state when being closed; the controlled end of a projection unit is connected with the output end of the electronic control unit, and the projection unit is turned on or off under the control of the electronic control unit; the projection unit receives and projects a projection image sent by the electronic control unit, and a projection focal plane of the projection unit is located on the conductive glass skylight; and the electronic control unit outputs a first control signal after responding to a car roof display signal, and controls the projection unit to be turned on while controlling the conductive glass skylight to be closed. In the scheme provided by the invention, the conductive glass skylight is easy to control and has a good display effect, and meanwhile, the projected image displayed on the conductive glass skylight has good uniformity, so that the user experience is improved.
Description
technical field [0001] The present application belongs to the technical field of automobile accessories, and in particular relates to a vehicle roof display device and a control method thereof. Background technique [0002] With the development of science and technology and the improvement of people's quality of life, my country's automobile industry has entered a period of rapid development, and people's requirements for driving experience are also getting higher and higher. The atmosphere of the roof plays an important role in satisfying the driving experience. [0003] In some existing vehicles, optical fibers are inserted into the ceiling of the interior, and the light of different colors is controlled by the optical fibers to form a starlight roof effect. In this implementation, the depth of optical fiber insertion is difficult to control and affects the brightness of the light spot. For vehicles with transparent sunroofs, the display effect is poor. At present, there ...
