It is provided. The optional display units 140, 150, 160, and 170 are made of one of PDLC, PSCT, and transparent OLED, and the panel is an expensive image control component. As the area where the selective display unit 140, 150, 160, 170 is used increases, the manufacturing cost increases by that amount. In order to prevent the manufacturing cost of the image display apparatus 100 according to an exemplary embodiment of the present invention, the manufacturing cost increases in FIG. 7. As shown, the transparent part 190 in which the polymer liquid crystal is not disposed is formed.

In this case, as described above, the local area parts 142 to 148, 152 to 158, 162 to 168, and 172 to 178 of each of the optional display parts 140, 150, 160, and 170 may be optional if the specific local area of the optional display part becomes opaque. The local area portion corresponding to the specific local area portion of the selective display portion located in the image output direction A of is controlled to be transparent so that the image image bound to the specific local area portion is controlled to be identified from the front.

On the other hand, the image display apparatus 100 according to an embodiment of the present invention, as shown in Figure 6, one of the case 110 in a state in which the image projection apparatus 120 is disposed outside the case 110 The reflection mirror unit 195 for reflecting the image projected from the image projection apparatus 120 in the direction in which the selective display units 140, 150, 160, and 170 are disposed may be mounted at an angle θ.

Since the image output direction A may be refracted through the reflective mirror 195 as described above, the image display apparatus 100 may be installed to meet the spatial constraints of the place where the image display apparatus 100 is installed.

In addition, the image reflected by the reflective mirror unit 195 is preferably provided to be reflected in the shape and size corresponding to the selective display unit (140,150,160,170), for this reason, each of the optional display unit (140,150,160,170) is an optional display unit disposed at the front end Minimizing shadows can be minimized by

Next, the operation principle of the image display apparatus according to an embodiment of the present invention will be described.

First, the main device 200 outputs an image signal for a predetermined image to be projected through the image projection apparatus 120 to the image output controller 121 through a signal line, and the image output controller 121 outputs the image signal. In response to the image projection apparatus 120 is converted into a recognizable signal and output to the image projection apparatus 120. Accordingly, the image projection device 120 turns on the light source in accordance with the converted signal to project a predetermined image in the image output direction (A).

At the same time, the main device 200 is configured to display images projected from the image projection device 120 according to a preprogrammed matter, in each of the local area portions 142 to 148, 152 to 158, 162 to 168 of the optional display units 140, 150, 160 and 170. 172 to 178) and outputs a control signal to the microcontroller 181 to be formed on the surface of the star, the microcontroller 181 is selected by the display device controller 180 in response to the control signal (140, 150, 160, 170) and each The transmittance control signal is output so that a driving voltage divided by each of the local regions 142 to 148, 152 to 158, 162 to 168, and 172 to 178 can be applied.

In this case, when the microcontroller 181 is not provided, the main device 200 is the display device controller 180, and each of the optional display units 140, 150, 160, and 170, and the local area units 142 to 148, 152 to 158, and 162 to 168. , 172 to 178) may directly output the transmittance control signal so that the driving voltage divided by.

As shown in FIGS. 2 and 3, the display device controller 180 receiving the transmittance control signal from the main device 200 or the microcontroller 181 may include the optional display units 140, 150, 160, and 170, and the local region units 142 ˜. 148, 152 to 158, 162 to 168, and 172 to 178 are applied to selectively control the transmittance of the local region of the desired selective display unit.

For example, as shown in FIG. 2, the first local region 142 of the first selective display unit 140, the second local region 154 of the second selective display unit 150, and the third selective display unit 160 of When the image of the image projection apparatus 120 is to be formed on the fourth local region 178 of the third local region 166 and the fourth selective display unit 170, the corresponding display units 140, 150, 160, and 170 are arranged in order. The local regions 142, 154, 166, and 178 are controlled to be opaque because no driving voltage is applied, and the remaining local regions 144, 146, 148, 152, 156, 158, 162, 164, 168, 172, 174, 176 of each of the optional display units 140, 150, 160, and 170 are controlled to become transparent and thus opaque. The image bound to the local regions 142, 154, 166, and 178 is identified from the front.

In addition, as shown in FIG. 3, the first local region 142 of the first selective display unit 140, the second local region 164 of the third selective display unit 160, and the third of the fourth selective display unit 170 are illustrated. When the image is formed in the four local region parts 176 and 178, the driving voltage is not applied to the corresponding local region parts 142, 164, 176 and 178 so that the image becomes opaque. The remaining local area parts 144, 146, 148, 152, 154, 156, 158, 162, 166, 168, 172, 174 are driven. By applying the control to be transparent, the image formed in the local region (142.164, 176, 178) to be identified from the front.

As described above, the image formed on each of the optional display units 140, 150, 160, and 170 is displayed at a different depth in front of the user according to the location of each of the optional display units 140, 150, 160, and 170 and the size of the predetermined interval spaced between each of the optional display units. You can feel the three-dimensional feeling when looking from the front.

On the other hand, the fourth selective display unit 170 is an image in the front end when there is no local region in which the image is formed in the first selective display unit 140, the second selective display unit 150, and the third selective display unit 160 installed at the front end. By controlling the local area portion corresponding to the unlocalized local area portion to become opaque, the image of the image projection apparatus can be seen without a sense of depth from the front.

As described above, according to the configuration and function of the image display apparatus according to an embodiment of the present invention, a plurality of display panels may be stacked by using a selective display unit, which is transparent by an applied voltage, as a display panel. An image having a sense can be provided, and even if a plurality of display panels are stacked, the image quality of the image can be reduced.

In addition, the projector uses an image projection type that projects an image to form an image on a predetermined screen. Therefore, it is unnecessary to use a special filter for preventing a light source and a moire phenomenon for a backlight, and using an existing LCD panel. Compared with multilayer displays, manufacturing costs are reduced and production processes can be simplified, and one optional display unit is formed by dividing into a plurality of local area units whose transmittance is individually controlled by a control signal. Since the shape and the size of each local area formed in the selective display of the corresponding to each other are formed to correspond to each other, the display manner of the display is varied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
