Abstract

PURPOSE: A portable foldable screen is provided to have a high brightness of a screen, to rotate the screen as a width or a height shape, to see the screen by only a user, to carry the screen conveniently, and to install the screen conveniently. CONSTITUTION: A portable foldable screen comprises a reflective screen (1), a turn table (2), a support stand (4), and a prop (5). In the reflective screen, image is imaged in a surface. The turn table is comprised in a rear side of the screen. In the support stand, the turn table is connected by each bending line (3). The prop is connected by the support stand and the bending line.

Description

Portable folding screen {Portable folding screen}

The present invention relates to a projection screen for watching an image projected from a mobile phone with a built-in projector, in particular the screen is rotated. The screen's field of view is limited so that no one else can see it. A portable folding screen, characterized in that it is easy to carry and install and use.

In order to add computer functions to mobile phones and to see the screen larger, portable phones with micro projector functions are being released.

   The micro-projector function is very low brightness, the mobile phone screen is often used in the vertical rather than the horizontal form and the mobile phone screen content should not be seen by other people as needed.

     In addition, the screen for this purpose must be portable, such as a mobile phone, should be easy to carry and easy to use and install.

In the past, there were no screens that could meet these conditions.

In the small screen structure with the screen size of 10 ″ -20 ″, the screen brightness is high, and the screen is rotated horizontally or vertically as needed, and the screen structure is easy to carry and easy to install and use. I would like to.

To solve the above problems

   A rotating shaft is provided on the back of the screen to rotate the screen as needed. The screen is composed of a surface reflective screen.

    Consists of a spherical or curved screen that properly adjusts the viewing angle

    When carrying, it is easy to carry and fold, and when using, it combines the screen with a folding case for easy unfolding.

In the present invention, since the screen is rotated by the rotation axis, the screen width: vertical aspect ratio 16: 9 screen can be rotated to 9:16 screen as needed, and the curvature and the reflective surface of the spherical or curved reflective screen are The viewing range is limited within the viewing range of the user, the brightness is increased by more than 2 times, and the reflective screen is configured in the case structure so that it is simple in the form of a thin film when carrying, and it is simple to install and can easily adjust the reflection angle of the screen.

The present invention is as shown in Figures 1, 2 and 3 (a), (b), (c)

The screen (1) consists of a front screen of the image on the screen surface

 The screen 1 is provided with a swivel table 2 having a circular ring structure in contact with the support 4 to rotate the screen 1.

 The swivel 2 consists of a support 2 joined by a bending line 3 in which a part of the support 4 can be freely folded on the upper end of the support 4.

   The lower part of the support 4 is provided with a pedestal 5 by forming a fold line (3) for easy folding

    Upper and lower sides of the pedestal 4 are provided with an angle support 6 for adjusting the installation angle of the screen 1.

    Such a structure of the present invention, as shown in Figure 2 and Figure 3 (a) when carrying the entire structure of the screen is folded (foldable) is easy to carry in a thin film structure

   In use, it is very easy to adjust the installation angle by setting up the screen 1 as shown in FIGS. 3 (b) and 3 (c) and fixing it by the angle support 6 at an arbitrary installation angle.

     When carrying, the screen 1 structure can be folded and inserted between the support base 4 and the base 5, and can be easily converted into a thin case and carried.

     In addition, as shown in (a) of FIG. 4, the screen 1 is simply rotated so that an image such as a movie uses the screen 1 in a horizontal form, while the image of a mobile phone screen may be used in a vertical form. .

     The present invention is composed of a screen (1) having a reflective surface having a surface reflectance of 2 or more, as shown in Figure 5, the curvature (R) of the screen (1) is twice the curvature of the projection distance of the projector (a) R), the projection distance of the projector d is configured to match the focal length F of the curvature R of the screen 1.

The curvature R of this screen 1 is applied to both spherical and curved screens.

    As described above, the screen 1 having the reflectance to the reflecting surface having a surface reflectance of 2 or more reflects the image of the projector a projected at the focal length F position of the screen 1 straight on the screen 1.

    The diffusion range that diffuses at the scattering rate of the screen itself in the straight reflection range of the screen 1 becomes the viewing range E.

     Within the viewing range (E) you can watch twice as bright

    Outside the viewing range (E), since the image is not visible, the user 7 cannot see it.

The present invention is composed of a structure in which the support (4), pedestal (5), the angle support (6) can be folded and the screen (1) is rotated by the swivel (2) can be used in the horizontal and vertical directions as needed Not only can it be easy to use and portable installation, and if necessary, only the user 7 will be able to view the screen (1) image.
