Abstract
The present application provides an electronic device. After a display screen of the electronic device is attached to a screen frame, the display screen extends beyond the screen frame at at least two opposite edges and extends toward the second side of the display screen by taking the screen frame as an axis, and then the display screen is mounted by a mounting structure connected with the screen frame, so that the display screen is kept flat by a tensile force provided to the display screen via the mounting structure.
Claims9
An electronic device, comprising:
- a host, configured to project light to a display screen and send an electrical signal to at least one electromagnetic driver;
- the display screen, configured to receive the light projected from the host and display an image on a first side of the display screen according to the light;
- the at least one electromagnetic driver, disposed on a second side of the display screen, and configured to receive the electrical signal sent from the host and drive the display screen to generate sound via vibration according to the electrical signal;
- a screen frame, attached to edges of the second side of the display screen, and configured to hold the display screen, wherein the display screen extends beyond the screen frame at at least two opposite edges and extends toward the second side of the display screen;
- and
- at least one mounting structure, disposed on the second side of the display screen;
- wherein the mounting structure has a first end connected with the screen frame and a second end connected with the display screen extending toward the second side, and is configured to keep the display screen flat;
- wherein the mounting structure is configured to keep the display screen flat by providing a tension to the display screen;
- wherein the display screen includes:
- a sound-generating substrate and a display structure, wherein the sound-generating substrate is attached to the display structure, and the at least one electromagnetic driver is disposed on one side of the sound-generating substrate;
- the sound-generating substrate includes:
- a first skin, a second skin and a middle layer;
- wherein the first skin and the second skin are attached to two sides of the middle layer, respectively;
- the first skin and/or the second skin of the sound-generating substrate extend beyond the screen frame at at least two opposite edges and extend toward the second side of the display screen;
- the second end of the mounting structure is connected with the first skin and/or the second skin of the sound-generating substrate extending toward the second side;
- wherein the first skin and the second skin are made of polymer material, wherein the polymer material includes:
- polyurethane or polystyrene.

A laser television, comprising:
- a box, configured to send projection light;
- a display screen, configured to receive the projection light and display an image on the display screen;
- at least one electromagnetic driver, configured to drive the display screen to generate sound via vibration;
- a screen frame, disposed on edges of the display screen, and configured to hold the display screen;
- and
- at least one mounting structure, having a first end connected with the screen frame and a second end connected with the display screen that extends, and configured to keep the display screen flat;
- wherein the mounting structure is configured to keep the display screen flat by providing a tension to the display screen;
- wherein the display screen includes:
- a sound-generating substrate and a display structure, wherein the sound-generating substrate is attached to the display structure, and the at least one electromagnetic driver is disposed on one side of the sound-generating substrate;
- the sound-generating substrate includes:
- a first skin, a second skin and a middle layer;
- wherein the first skin and the second skin are attached to two sides of the middle layer, respectively;
- wherein the first skin and/or the second skin of the sound-generating substrate extend beyond the screen frame at at least two opposite edges and extend toward the second side of the display screen;
- the second end of the mounting structure is connected with the first skin and/or the second skin of the sound-generating substrate extending toward the second side;
- wherein at least one opening is disposed on the first skin and/or the second skin of the sound-generating substrate extending toward the second side, and the at least one opening has one-to-one correspondence with the at least one mounting structure;
- a hollow rivet is disposed on one of the at least one opening, and the second end of the at least one mounting structure is connected with the hollow rivet disposed on one of the at least one opening.
