Display apparatus

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.

AI Technical Summary

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 poor bending uniformity of the curved display screen, which forms a shortcoming for high-quality display device products

[0004] Since the density uniformity of the material forming the support backplane 10 is relatively fixed, for the same display screen 1, different curvatures require support backplanes 10 with different pre-curvatures, resulting in numerous models, which is not conducive to manufacturing costs and product management

At the same time, the existing curved surface display devices still have the problem of fixed bending radius, fixed optimal viewing distance, and limited application occasions.
