The present invention relates to an integrated projector device equipped with a screen for outputting an image.

As the information age rapidly develops, the importance of a display device that implements a large screen is being emphasized. As an example of a device implementing such a large screen, there is a projector having a function of enlarging and projecting an image.

Recently, as the performance of a projector is considered important, various new attempts are being applied in terms of hardware or software. For example, there is an attempt to implement a projector using a laser diode (LD), a light emitting diode (LED), an organic light emitting diode (OLED), and a phosphor as a light source.

For example, when a voltage is applied to both ends of a laser diode, coherent light having a certain wavelength, that is, laser, is emitted through stimulated emission and constructive interference. Lasers emitted from each of the plurality of laser diodes are condensed through a lens to form a high-brightness light source. Recently, with the miniaturization of the projector itself, users' needs to use it indoors as well as outdoors while carrying it are increasing.

However, in order to output an image from the projector, a screen is required, and in order to display the output image in an appropriate size, it is inconvenient to install the screen at an appropriate distance from the projector module.

Accordingly, the present invention is to provide an integrated projector in which a screen for outputting an image and a projector are integrally formed.

In order to achieve the object of the present invention, a projector device according to an embodiment includes a projector module for outputting an image, an extension unit including a plurality of extension units mounted on the projector module and having a variable length, and the plurality of extension units. A screen is connected and realized in an expanded state and a collapsed state as the lengths of the plurality of extensions change, and the image is displayed on the screen in the expanded state.

As an example related to the present invention, a speaker unit including at least one speaker module mounted on a portion of the plurality of expansion units may be further included, and the at least one speaker module may be connected to one corner of the screen. Accordingly, there is no need to provide a separate speaker module.

As an example related to the present invention, a support part including at least one support frame disposed in the remaining area of the plurality of expansion parts is further included, and the at least one support frame and a part of the at least one speaker module are placed on the ground. The screen is supported on and the speaker module can be deactivated when supported on the ground. Accordingly, the screen may be arranged so that an image can be output based on the projector module.

As an example related to the present invention, a sensor unit for detecting a distance between the screen and the projector module and a movement of the screen may be further included, and the projector module may output the image based on the distance and the movement of the screen. And since the output direction can be changed, an appropriate image can be provided according to the position of the screen.

According to the present invention, the screen is connected to the projector module in a movable state, and the screen can be accommodated based on the deformation of the extension, so it is easy to use anywhere because there is no need to separately install the screen and the projector module.

In addition, since the length of the extension part fixing the screen is variable, the position of the screen can be adjusted according to the output image, and the sensor unit detects the position of the screen to output guide information or change the output state of the image. may be provided with an image of improved quality.

FIG. 5 is a conceptual diagram for explaining a structure for adjusting the position of a screen by the projector device of FIG. 3A.

The first to fourth expansion parts 810, 820, 830, and 840 according to the present embodiment may be made of a deformable elastic material. That is, it may be made of a material that can be bent by an external force.

For example, the second and fourth extension parts 820 and 840 may be bent when the screen 400 is unfolded. When bent by the user by the bent second and fourth extension parts 820 and 840 , the upper end of the screen 400 moves adjacent to the body part 600 . Accordingly, the user sees the upper end length W1 shorter than the lower end length W2. Although the drawings are shown as a pair of extensions are deformed, it is not limited thereto. For example, a more rounded screen may be implemented by deforming one extension so that only one corner of the screen is bent, or by deforming all four extensions.

According to this embodiment, the user can change the shape of the screen using a deformable extension.

6A to 6D are conceptual diagrams for explaining a control method of a projector device based on the length of an extension and an output image.

Referring to FIG. 6A , the projector module 100 outputs a first image 10 . The first image 10 is displayed on the screen 400 unfolded in use. The screen 400 according to this embodiment is formed with different horizontal and vertical lengths. In a state where the screen 400 is supported by the support frames 311 and 312, the first and second speaker modules 321 and 322 output auditory data.

The screen 400 is rotated 90 degrees, and the screen 400 is supported from the ground by the second speaker module 322 and the second support frame 312 . Due to the rotation, a short area of the screen 400 is disposed substantially parallel to the ground.

In this case, the projector module 100 is also rotated by about 90 degrees, and the control unit of the projector module 100 rotates the output direction of the image by 90 degrees and outputs the image. That is, the output direction of the image is the same with respect to the ground. In addition, the control unit adjusts the output ratio or output size of the video. That is, the first image 10 displayed on the screen 400 is displayed on the screen 400 as a reduced image 11 .

Accordingly, the user can receive an image in the same output direction even when the projector device 1000 rotates and the ratio of the screen 400 changes, and the entire image can be displayed on the screen 400 without loss of area. can

In addition, the second speaker module 322 supporting the ground may block the output of auditory data. That is, the speaker module supported on the ground is inactivated, and the remaining speaker modules are selectively activated or controlled to increase in sound.

Referring to FIG. 6B, when the distance between the screen 400 and the projector module 100 is extended from the first distance D1 to the second distance D2 in use, the projector module 100 outputs Controls the output size of the image to be played. That is, this corresponds to the case where the length of the plurality of extensions increases.

The projector device 1000 further includes a sensor unit that detects the distance of the screen 400 . The sensor unit may include a distance sensor for detecting a distance or a sensor module for measuring a distance through lengths of the plurality of extension parts. Accordingly, the sensor unit can detect the distance between the projector module 100 and the screen 400 .

For example, when the distance between the screen 400 and the projector module 100 increases from the first distance D1 to the second distance D2, the output size of the image is increased or the output image is changed. It can be controlled to output more clearly.

Referring to FIG. 6C , the controller detects the distance between the projector module 100 and the screen 100 through the sensor unit. The control unit of the projector module 100 compares the size of the output image and the distance information. The control unit of the projector module 100 provides first guide information 21 for guiding the movement of the screen when the image is output to the outside of the screen 400 or when it is determined that the size of the screen 400 is too large. can output

The first guide information 21 may be output together with the image 10 . The first guide information 21 may include text or guideline formed along the edge of the image 10 .

The user can adjust the expansion unit through the first guide information 21 and change the position of the screen so that all output images are displayed on the screen.

6D describes a case in which the screen 400 is arranged larger than the output size of the output image. The projector module 100 controls to output guide information when the display area of the screen is larger than the size of the output image (ie, when a blank space occurs) through the distance information of the screen detected through the sensor unit. . In particular, when the output ratio of the image and the ratio of the width and height of the screen 400 do not match, the controller outputs the second guide information 22 .

In this case, the user can adjust the size of the screen itself according to the second guide information 22 . The control unit may also output a guide line 23 for adjusting the size of the screen 400 . The guide line 23 may correspond to an edge area of the image.

Referring to FIGS. 2B and 6D together, the user uses the plurality of additional connection holes formed in the screen to form the blank area 400' of the screen 400 so that the support part and the speaker part and the screen ( 400) can be connected.

Accordingly, the user can implement a screen suitable for the output size of the image.

7A is a conceptual diagram for explaining a control method of a projector device according to an embodiment of the present invention, and FIGS. 7B to 7D are conceptual diagrams for explaining a control method for a projector device according to an embodiment.

Referring to FIG. 7A and FIG. 7B , the sensor unit of the projector device 1000 according to an embodiment of the present invention detects the distance D between the screen 400 and the projector module 100 (S1100).

The control unit of the projector device 1000 compares the size of the output image to be output on the screen 400 and the distance to the screen 400 (S1200). The controller detects the distance between the projector module 100 and the screen 400 in a state in which the image is output on the screen 400 or in a state in which the output image is selected.

The controller determines whether the image output from the projector module 100 can be output to the space of the screen 400 separated by the detected distance D. Accordingly, the projector module 100 outputs an indicator or adjusts the output size of an image (S1300).

The projector module 100 may output an image 10 in which the output size of the first image 12 being output is reduced. The projector module 100 may calculate the ratio to be output based on the basic size of the image to be output and the distance D.

Alternatively, the projector module 100 may output first guide information 21 . In this case, the projector module 100 may not output the image that was being output, and the first guide information 21 is the length of the extension to be adjusted or the distance between the screen 400 and the projector module 100. may contain information about

Accordingly, the user may be provided with an image adjusted to fit the screen.

Referring to FIG. 7C , the projector module 100 outputs an image 13 on the screen 400 . However, the control unit displays the image 13 in the entire display area on the screen 400 based on the distance between the projector module 100 and the screen 400 and the output size (ratio) of the output image. If it is determined that it does not, the third guide 24 is output.

The third guide 24 is output together with the image 13, and may be configured as a direction indication to expand or reduce the size or ratio of the image 13. Accordingly, the user can change the output setting of the image 13 according to the third guide 24 . Here, the output setting may include an output ratio of the image, an output size, and the like.

Referring to FIG. 7D , in the projector device 1000 according to the present embodiment, the screen 400 is unfolded by an external force. The control unit 400 detects the distance between the screen 400 and the projector module 100 or the length of the extension part detected by the sensor unit. Accordingly, the control unit of the projector device 1000 can determine whether the screen 400 is unfolded in a state capable of outputting an image. The controller of the projector device 1000 activates the projector module 100 when the screen 400 is in an unfolded state to the extent that an image can be output. When activated, the projector module 100 may output an activation display 30 on the screen 400 .

Conversely, when the screen 400 is folded again, the controller may switch the projector module 100 to an inactive state.

Since the projector module 100 is controlled to be activated only when it is in a usable state, power consumption while not in use can be cut off.
