Problems solved by technology

Normally, the supporting backplane 10 is arc-shaped and pre-bent to a smaller radius, but many factors such as the shape of the arc, the radius of pre-bending, the thickness of the plate, and the uniformity of the density of the material all affect the resulting The rebound force has a great influence, resulting in poor consistency of the rebound force of the finally obtained arc-shaped support backplane 10, so that the final curvature radius of the assembled display screen 1 has a large distribution around the target curvature radius value. The target curvature radius value deviates more, resulting in

Embodiment 1

[0037] This embodiment provides a display device, the back plate mechanism in the display device is easy to process, the resilience consistency is better, and the variable curvature can be further adjusted to form the back plate mechanism, and then the curved surface display with better curvature consistency can be assembled device.

[0038] Such as image 3 As shown, the display device includes a display screen 1 and a back plate mechanism 2 arranged on the non-display side of the display screen 1, wherein the back plate mechanism 2 includes a plurality of straight support plates 21, and two adjacent straight support plates 21 are connected at an angle, and the display screen 1 is arranged tangentially with two adjacent straight support plates 21 , and multiple straight support plates 21 make the display screen 1 form a curved structure. The different included angles between two adjacent straight support plates 21 correspond to different radii of the inscribed circles formed...

Embodiment 2

[0050] This embodiment provides a display device, the back plate mechanism of the display device is easy to process, the resilience is better in consistency, and the curved surface display device with better curvature consistency is assembled. The difference between this embodiment and Embodiment 1 is that the curvature of the back plate mechanism 2 in this embodiment is fixed and not adjustable.

[0051] Two adjacent straight support plates 21 in the back plate mechanism 2 form a fixed-angle angle portion, and the overall structure formed by all the straight support plates 21 makes the display screen 1 form a set curved surface structure. Such as Figure 8 As shown, the overall structure formed by all the straight support plates 21 is symmetrical with respect to the center vertical line of the display screen 1, thereby forming a center-symmetrical curved display device. Wherein, the angle range between two adjacent straight support plates is 30°-270°, and the shape displayed...

Abstract

The invention belongs to the technical field of display and concretely relates to a display apparatus comprising a display screen and a back plate mechanism arranged on a non-displaying side of the display screen. The back plate mechanism comprises a plurality of straight supporting plates; two adjacent straight supporting plates are connected and form an included angle; the display screen is arranged between the two adjacent straight supporting plates and tangent to the same; and the display screen forms a curved surface structure by the plurality of straight supporting plates. The back plate mechanism of the display apparatus can be easily manufactured, possesses even resilience and can further possesses various curvature; and a curved display device having great consist curvature can be achieved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display device. Background technique [0002] Currently, the mainstream display device is a flat panel display device. With the advancement of science and technology, curved surface display devices have emerged. The curved display device can make the viewer feel the theater effect, so it is a popular trend. [0003] In the manufacture of existing curved surface display devices, especially in the manufacture of large-size curved surface display devices, such as figure 1 and figure 2 As shown, the most commonly used method is: directly apply external force on both ends of the flat panel display, such as placing the display 1 in a curved support backplane 10 (also called a module frame) structure, through the external force of the support backplane 10 , counteract the elastic force of the display screen 1, so that the display screen 1 remains in a curved shape. T...
