DETAILED DESCRIPTION OF THE INVENTION

[0029] Please refer to FIG. 2 to FIG. 4, the magnifying display screen device A of the present invention includes:

[0030] a stand 1, a shaft 11 is set on it;

[0031] a display module 2, its one side is pivoted on the shaft 11, the display module 2 is provided to display an image;

[0032] a reflective module 3, which includes a reflective sheet 31 and a light shield 32, the reflective sheet 31 is a convex mirror, the reflective sheet 31 is provided to receive the image displayed by the display module 2 and reflect a reflection image, the light shield 32 is fixed on two sides of the display module 2 and a box body is formed;

[0033] a magnifying module 4, which includes a magnifying sheet 41 and a bracket 42, the bracket 42 is fixed to the top of the display module 2, the magnifying sheet 41 is a concave mirror, principle of virtual imaging is imaging by using a concave mirror, the imaging formula of a concave mirror is: 1/p+1/q=1/f, wherein f: focal distance, q: object distance, p: image distance. By using a general magnification, virtual images could be enlarged and virtual image distance could also be farther at the same ratio, the magnifying sheet 41 is provided to receive an reflection image of the reflective sheet 31 and display a magnified image of the reflection image.

[0034] The above shaft 11 includes an elastic piece 111, the shaft 11 could be rotated at will to adjust and fix its angle by the elasticity provided by the elastic piece 111, the position and the angle of the shaft 11 would be fixed after being adjusted because the elasticity of the elastic piece 111 is pushed and supported it.

[0035] The stand 1 is an L-shaped frame, multiple non-slip pads 12 are set on its bottom to prevent the magnifying display screen from slipping.

[0036] The display module 2 is a LCD screen, a LED screen, a computer screen or a TV screen.

[0037] The above display module 2 further includes an input connector 21, a back cover 22, the input connector 21 is a HDMI slot, a DVI slot, a DisplayPort slot, a D-sub slot, a USB slot, a SD memory card slot, the back cover 22 is provided to cover outside the input connector 21.

[0038] The above display module 2 further includes a keypad 23, the keypad 23 is provided to operate the display module 2. The keypad 23 includes a power key 231, a menu key 232, an exit key 233, a cursor up key 234 (shown as sign <) and a cursor down key 235 (shown as sign >). The power key 231 is used to start or close the display module 2; the menu key 232 is pressed to shown a screen display menu; when the display module 2 shows the screen display menu, the exit key 233 is pressed to exit the screen display menu; the cursor up key 234 or the cursor down key 235 is pressed to change the setting of current function.

[0039] The above display module 2 further includes a speaker unit (not shown in figure), the speaker unit is provided to inform users voice messages.

[0040] The above display module 2, the shaft 11 is pivoted to its one side, its ideal pivot position is the back side of the display module 2 (namely, the shaft 11 is fixed to the back side of the display module 2) or the bottom of the display module 2 (namely, the shaft 11 is fixed to the bottom of the display module 2).

[0041] The above bracket 42 is fastened to the display module 2 by using multiple screws 421, a back cover 22A is covered outside of the screws 421.

[0042] Please refer to FIG. 5, FIG. 6, the projection light path L of the present invention includes a reflective light path L1 and a magnifying light path L2, wherein when a user uses the magnifying display screen device, first, the input connector 21 of the display module 2 is used to connect to a mobile phone (or a computer, a video player, a USB flash drive or a SD memory card) to let the display module 2 displays an image, through the reflective light path L1 of the reflective sheet 31, the eye E of the user could receive the reflection image of the reflective sheet 31 through the magnifying sheet 41, through the magnifying light path L2, the user could watch the magnified image in the remote imaging area E1. As the illustration of the projection light path L of the present invention, the implementation of the present is using the principle of virtual imaging of concave mirrors in Optics to let objects be magnified several times and imaged far longer than several times of the object distance (about two meters). The problem of watching near objects for a long time could be solved by using the optical technology, what the eyes see is magnified with a visual distance of two meters away, so that the users would not have myopia caused by too close to the screen for a long time.

[0043] In the present invention, since the projection light path L of the image has already be optimized with fixed distances and fixed angles of the display module 2, the reflective module 3 and the magnifying module 4, a user needs not to adjust the distance and the projection angle between the display module 2, the reflective module 3 and the magnifying module 4, the user only needs to slightly adjust the angle of the shaft 11 according to user's body size and watching position to easily obtain the optimized watching angle, so that the user could watch an ideal magnified image, to thereby reduce the burden on eyes. Simultaneously, since the present invention could be connected to a mobile phone, a computer, a video player, a USB flash drive, a SD memory card, the screen image of the mobile phone, the computer, the video player, the USB flash drive, the SD memory card could be magnified, to thereby effectively improve its range of use.
