Embodiment 1

[0015] like figure 1 As shown, a projection electronic photo frame includes a micro projector 101; a screen 103; a mechanical photo frame 105; an electronic control device 107;

[0016] The electronic device 107 stores or receives the information of the photo, and sends it to the micro projector 101, and the micro projector projects a large-format picture. projected onto the screen 103 . The screen is installed in the mechanical photo frame 105 described above. The above-mentioned micro projector 101 is connected with a mechanical photo frame 105 by a mechanical device 109 . The above-mentioned electronic device 105 is installed in the mechanical photo frame or on the back of the screen. Since the weight of the micro projector is very light, the weight of the other components mentioned above is also very light, so when in use, the user installs the mechanical photo frame on the wall or on the desktop in a similar way to the ordinary photo frame.

[0017] The above-mentione...

Embodiment 2

[0020] like figure 2 As shown, a projection electronic photo frame includes a micro projector 201 ; a screen 203 ; a mechanical photo frame 205 ; and an electronic control device 207 . The pico projector 201 and the electronic device 207 are connected together by a mechanical device 209 and are installed on the ceiling 211 . The screen 203 and the mechanical photo frame 205 are connected together and mounted on the wall. Different from Embodiment 1, the two are installed separately.

[0021] The electronic device 207 stores or receives the information of the photo and sends it to the micro projector 201, and the micro projector projects a large-format picture. projected onto the screen 203. The screen is installed in the mechanical photo frame 205 described above. The above-mentioned pico projector 201 is connected to the electronic control device 207 by a mechanical device 209 . The electronic device is installed in the mechanical device, and the mechanical device 209 i...

Embodiment 3

[0023] like image 3 As shown, a projection electronic photo frame includes a micro projector 301; an electronic control device 307;

[0024] The electronic device 307 stores or receives the information of the photo and sends it to the micro projector 301 , and the micro projector projects a large-format picture on a white wall 305 . Different from Embodiments 1 and 2, the screen described in Embodiment 3 can be a white wall, which can reduce the system cost.

[0025] In the above three embodiments, the electronic control device may further include a TV receiving circuit, and the device can be used as a TV when no photos are displayed.

[0026] In the above three embodiments, the electronic control device may further include a wireless or wired network connection circuit, and the device can be used to surf the Internet when the photo is not displayed.

Abstract

The invention discloses a projective electronic photo frame, which is formed by combining a miniature projector, a projection screen, a mechanical photo frame, an electronic control device and a mechanical device for connecting the parts. The electronic control device transmits picture information to the miniature projector. The miniature projector projects a picture onto the projection screen of the photo frame, and is preferably a super short-throw projector to shorten a projection distance. The projection screen is preferably a high-contrast and high-resolution screen to darken ambient light, improve projection brightness and ensure image contrast and definition under any ambient light to achieve a good visual effect. The size of the electronic photo frame can be far smaller than that of the conventional liquid crystal display-based electronic photo frame, so that a high-definition large screen is provided for image display.

Description

technical field [0001] The invention relates to an electronic photo frame, in particular to a projection type electronic photo frame. Background technique [0002] With the development of modern electronics, electronic photo frames appear in many occasions such as homes, desks, shops and even coffee shops. The traditional electronic photo frame is mainly composed of LCD liquid crystal display. Due to cost and weight constraints, its screens cannot be too large, most are smaller than 10 inches. High-contrast, large-format photos cannot be displayed. Not a complete replacement for traditional large format photos. [0003] Therefore, the market is in urgent need of an electronic photo frame capable of displaying a large format. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a projection-type electronic photo frame that displays large-format photos for people to watch. [0005] The technical scheme of the present invention is: a proje...
