Description

TECHNICAL FIELD [0001] The present invention relates to a touch-enabled screen device having a frame and a projector-integrated screen device for preventing shadows from being generated. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

The present invention relates to a touchable screen device having a frame and a projector-integrated screen device for preventing shadows from being generated. More specifically, the present invention relates to a device for preventing the generation of shadows due to the touch of an object by providing a protective film on the front surface of the touchable screen in combination with the frame.

Projectors are typically used to provide lectures or presentations at schools, academies, and conferences, or through lectures on projectors and screens on the wall.

It is a common practice to lecture the projector with a laser pointer on the screen when presenting a lecture or presentation through a large screen installed on the projector and the wall. However, since the contents of the prepared lecture are reflected directly on the screen through the projector, the contents to be explained further during the lecture are transmitted only to the voice information, and the lecturer has to rely on the memory of the lecture contents. Therefore, there is a disadvantage that it is impossible to express a written form and a line drawing which require supplementary explanations in order to increase the understanding of the learner.

In order to overcome such disadvantages, a hardware type sensor is installed on the inner and outer surfaces of the touch panel in a large frame structure, or a flexible (flexible) structure constituting a sensing line is formed by using wires and indium tin oxide (ITO) It was developed to use the electronic pen by recognizing coordinates by installing a touch panel of one material.

However, such a flexible touch panel has a problem that movement occurs when touching using an electronic pen, a finger, or the like, and the sensing coordinates are not accurately measured. Further, there is a problem that the user hides the light projected from the projector due to the approach of the electronic pen, the finger or the like for touching the touch panel or a touch, thereby generating a shadow and covering the image.

The touch panel 20 includes a base panel 22, a touch sensing line 24, and a protection sheet 26. The touch panel 20 is provided with a sensing line 24 adhered to the upper surface of the base panel 22 with an adhesive and a protective sheet 26 adhered to the upper surface of the sensing line 24 using an adhesive, The panel 20 can be constructed. The protective sheet 26 may be applied with an adhesive to adhere to the screen 52. Or the protective sheet 26 can display an image transmitted from the projector 10 like the screen 52. [

The sensing line 24 may be composed of the conductive wire 24-1 and the insulating layer 24-2 configured to surround the conductive wire 24-1. The sensing line 24 may be installed by forming a matrix structure in the X axis and the Y axis.

Fig. 3 is a view showing a structure of a frame and a drive mode thereof, and Fig. 4 is a view showing a form in which the touch panel is wound.

3 and 4, the frame 30 includes a first frame 32, a second frame 34, a third frame 36, a fourth frame 38, a tiltable member 31, (33). The first frame 32 and the second frame 34 are installed at both ends of the touchable screen 50 so as to face each other. The tiltable member 31 may be selectively installed in any one of the first frame 32 and the second frame 34. [ The pivoting member 31 can be connected to the third frame 36 and the fourth frame 38 and can be rotated to be rotatable. The third frame 36 and the fourth frame 38 are driven in a fan shape by the tiltable member 31 and fixed by the fixing means 33. The third frame 36 and the fourth frame 38 are combined with the fixing means 33 to have a rectangular shape. That is, the frame 30 can be folded or unfolded through the tiltable member 31 and can be fixed by the fixing means 33. The frame 30 fixes the touchable screen 50 associated with the frame 30 when it is fixed in a rectangular shape. The fixed touchable screen 50 is free from distortion of the image projected from the projector 10 because the movement due to the user's touch is fixed. Further, when the frame 30 is folded, the touchable screen 50 can be wound, so that it can be easily stored and moved.

Referring to FIG. 5, a protective film 40 may be provided on the front surface of the touchable screen 50 according to the second embodiment. The protective film 40 is made of a transparent material and can be installed apart from the touchable screen 50. In addition, the protective film 40 is fixed by the frame 30 to prevent movement due to the touch of the object, thereby accurately recognizing the touch coordinates.

The projector 10 must be used in combination with the first frame 32. [ The projector 10 transmits an image between the touchable screen 50 and the protective film 40 so that an image is displayed on the front surface of the touchable screen 50. [ The protection film 40 prevents the image transmitted from the projector 10 from being obscured by the touch of the object, thereby preventing the generation of shadows.

The touchable screen 50 may include a touch panel 20 including a touch sensing line for sensing a touch of an object and a screen 52 using the touch panel 20 attached thereto. The screen 52 can be selectively used either as a flexible material or as a rigid material.
