Curved Surface Display Device and Its Curvature Adjusting Mechanism

Abstract

The invention discloses a curvature adjusting mechanism of a curved surface display device. The mechanism comprises a bottom plate and a traction assembly, the bottom plate is used for being connected with the two ends of a flexible display screen, and the traction assembly is fixed to the bottom plate and used for being connected with the middle of the flexible display screen; the traction assembly comprises a rotary shaft, a cam and a translation part, the cam is fixed at one end of the rotary shaft, and the other end of the rotary shaft is rotationally arranged on the bottom plate; the translation part comprises a connecting part used for being connected to the back of the flexible display screen, and a blocking strip perpendicular to the connecting part; the rotary shaft is arranged between the free end of the connecting part and the blocking strip; the cam surface of the cam abuts against the surface, facing the connecting part, of the blocking strip. The invention further discloses the curved surface display device. The curvature of the display screen can be adjusted through the special curvature adjusting mechanism, and under the rotation of the rotary shaft, the cam drives the translation part to drive the middle of the flexible display screen to be indented; a plurality of bending curvatures of the flexible display screen can be achieved by utilizing the contact fit between different portions of the cam surface and the translation part, and the watching requirements of different environments are met.

Description

technical field [0001] The invention relates to the technical field of curved surface display, in particular to a curved surface display device and a curvature adjustment mechanism thereof. Background technique [0002] With the development of display technology, curved surface display technology has gradually emerged and is sought after by major manufacturers of electronic display devices and display panels. The curved screen of the display device can keep the distance from the entire screen to the lens of the human eye consistent, which can ensure the clarity of images on both sides of the screen. [0003] At present, there are two main ways to realize the curved surface of the curved surface module on the market. One is to use the bracket to force the backplane to bend into the target curve and then fix the backlight module. The other is to directly form the curved surface structure on the backplane and then fix the backlight module. Group. However, the backplanes of th...

Problems solved by technology

However, the backplanes of the above two structures cannot adjust the curvature of the curved surface module, and can only be displayed with a single fixed curvature.

However, the optimal curvatures suitable for viewing environments of different sizes are different, but general fixed-curvature curved displays cannot meet the requirements of environmental compatibility
