1 is a schematic view showing an image of a projector 200 displayed on a first display unit 400 in a first image transmission direction X and FIG. 3 is a schematic view of the projector 200 according to an embodiment of the present invention. Referring to FIG. 3, Is transmitted by the image transmission path 300 in the second image transmission direction Y and is projected to the outside of the vehicle by the first image diffusion unit 700 disposed at the end of the image transmission path.

The projector 200 of the present invention can selectively project an image in the first image transmission direction X or the second image transmission direction Y by the first driving unit 201. [ That is, the first driving unit 201 can operate in two directions. It is also preferable that the first image transmission direction X and the second image transmission direction Y of the projector 200 face the front of the vehicle.

The first driving unit 201 can be applied to any device capable of driving the projector 200 in two directions (X, Y). The first driving unit 201 may be a rotatable driving motor integrally formed at the end of the projector 200. The operation of the motor can be operated by a control unit (not shown), and can be applied manually or automatically. The rotational center axis of the rotatable drive motor can coincide with the longitudinal center axis C of the image transmission path.

In the case of the automatic method, according to the sensor recognizing the external environment, for example, when the external light is too bright, it operates in the first image transmission direction X as shown in FIG. 1, A system operating in the transmission direction Y may be applied.

A driving system in which the projector 200 operates in the first image transmission direction X will be described with reference to the embodiment of FIG. The projector 200 may be disposed closer to the driver than the first display unit 400 on the basis of the driver. That is, the projector 200 can be positioned in front of the first display unit 400. [ The projector 200 can be positioned in front of the first display unit 400, thereby enhancing the space utilization of the integrated projector display device 100. In the case of a conventional rear screen type projector, there is a problem that the visibility due to external light is lowered, and there is a problem in that the structure of the screen is complicated and the manufacturing cost is increased. The present invention solves the problem of low visibility due to external light by applying a front screen, i.e., a reflective screen, and enables the implementation of the first display unit 400 by a simple and inexpensive construction.

The first display unit 400 may be a vehicle cluster 400. Basically, since a transmitted image must be reflected, it is possible to apply a sheet having a reflection function. A sheet of various materials such as a metal sheet, a composite sheet, and a cholesteric polarizing sheet which can have a reflection function can be applied. Further, it is possible to further apply an optical film capable of improving optical function such as improvement of visibility and straightness of light by external light.

The present invention may further include a second image diffusion unit 701 that diffuses an image transmitted to the first display unit 400 and is disposed in a first image transmission direction (X) path. As shown in FIG. 1, the second image diffusion unit 701 may be formed integrally with the first display unit 400 or may be formed as a separate device. The second image diffusion unit 701 may be any structure as long as it optically diffuses the image of the projector 200. It is preferable to apply the convex lens 701 which can be easily applied.

1, the projector display apparatus 100 for a vehicle according to the present invention may be formed integrally with the first display unit 400 or may have a separate insertion structure.

Hereinafter, a process of projecting the image of the projector 200 shown in FIGS. 2 and 3 in the second image transmission direction Y and transmitting the image to the second display unit 500 and the outside of the vehicle will be described.

The projector 200 of the present invention can be turned in the second image transmission direction Y by the first driving unit 201 to project an image. As shown in FIGS. 2 and 3, the image of the second image transmission direction Y may include an image transmission path 300 for guiding the image transmitted from the projector 200.

Between the video transmission path 300 and the projector 200, an optical medium (non-base material) for assisting the transmission of light can be disposed. The optical medium transmits the image to the image transmission path 300 without distortion of the image.

A reflective member 600 may be disposed between the image transmission paths 300. The reflective member 600 reflects the image guided by the image transmission path 300 to the second display unit 500. The reflective member 600 may be a reflective mirror 600, and the reflective member 600 may be disposed on any surface of the reflective surface 600, which is not limited thereto.

The reflective member 600 may include the second driving unit 601 integrally. The second driving unit 601 drives the reflective member 600 to perform selective reflection. The reflective member 600 transmits the image to the second display unit 500 through the reflection function when the reflective member 600 is up between the image transmission paths 300 by the operation of the second driving unit 601, The image is transmitted to the first image diffusion unit 700 at the end of the image transmission path 300 to transmit the image to the outside of the vehicle. The angle formed with the longitudinal direction of the image transmission path 300 may be varied according to the inclination and curvature of the vehicle front glass 500 that is the second display unit 500. [

Up and down operations of the reflective member 600 are realized by the second driving unit 601. The second driving unit 601 is also operated in the same manner as the first driving unit 201, (Down). ≪ / RTI > Preferably, the link structure can be achieved by driving the motor.

When the reflective member 600 is up, the image is transmitted to the second display unit 500 as shown in FIG. A third image diffusion unit 702 may be disposed between the reflective member 500 and the second display unit 500. Like the first image diffusion unit 700, the third image diffusion unit 702 may have any optical configuration capable of diffusing an image, and preferably a convex lens may be disposed. The image realization by the second display unit 500 serves as a head-up display (HUD). The application of the technology to the head-up display is well known and is not described in the description of the present invention.

When the reflection member 600 is down, the image is transmitted to the first image diffusion unit 700 disposed at the end of the image transmission path 300 as shown in FIG. At this time, when the reflection member 600 is down, it is down in parallel with the inner bottom of the image transmission path 300 without disturbing the transmission of the image transmitted to the image transmission path 300. When it goes down, the surface opposite to the reflection function of the reflection member 600 operates so as to be directed to the inside of the image transmission path. It is preferable that the reflection surface of the reflection member 600 is formed in the same manner as the material, the curvature, and the like of the image transmission path.

The first image diffusion unit 700 is preferably an optical convex lens having a light diffusion function. The image transmitted to the first image diffusion unit 700 is diffused to a screen (not shown) outside the vehicle, and a TV, a movie, and the like implemented in the projector can be appreciated. The exterior screen for the vehicle may be formed separately from the vehicle, or may be arranged separately from the vehicle so as to be integrated with the vehicle.

The projector 200 of the present invention may be a DLP (Digital Light Processing) projector. The technical details of the DLP projector are well known in the art, and therefore, the present invention is not described herein.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have.
