Abstract

The invention relates to a curved-surface display device, which comprises a curved-surface display panel, at least a printed circuit board and at least two chip on film tapes. The printed circuit board is arranged on one side of the curved-surface display panel. At least two chip on film tapes are electrically connected with and arranged between the curved-surface display panel and the printed circuit board, and are separately arranged on two sides of a phantom line, and the phantom line goes through the printed circuit board and is vertical to the tangent line of the part that the phantom line intersects with the curved-surface display panel, wherein the chip on film tapes on the different sides of the phantom line are in different shapes and are in mirror symmetry with the phantom line as a standard. The pulling tolerance is improved when the chip on film tapes are bended, and the crack risk of the chip on film tapes is reduced.

Description

technical field [0001] The present invention relates to a curved display, in particular to a curved display that prevents a chip on film (COF) from being damaged due to pulling. Background technique [0002] A curved display is a display with a curved display surface. When watching a curved display, the distance between the viewer's eyes and each position of the curved display is about the same, and the viewer can watch the picture displayed in the central area or the left and right edge areas at a near right angle, so compared with Compared with flat-panel displays, curved-surface displays will not cause problems such as brightness deviation and color deviation when viewed at large viewing angles. In addition, curved displays have a stereoscopic-like visual effect. Therefore, curved displays have become highly desirable display products. [0003] In the curved display, a chip-on-film tape is provided to connect the curved display panel and the printed circuit board, wher...
