Abstract

The invention provides a flexible circuit board of a display screen, which comprises a circuit board body, wherein the side surface of the middle part of the circuit board body is attached to the sidesurface of a backlight module; two sides of the middle part are respectively connected with a first bending part and a second bending part; the first bending part is connected with a golden finger; the second bending part is connected with the back surface of the backlight module; the bending angles of the first bending part and the second bending part are adjusted to reduce stress; a first bending guide line and a second bending guide line are arranged in the first bending part and the second bending part respectively; a first row of bending guide grooves and a second row of bending guide grooves are formed in the circuit board body along the first bending guide line and the second bending guide line respectively; and the first row of bending guide grooves and the second row of bending guide grooves are parallel to each other. By arranging the first bending part and the second bending part, the middle part is enabled to be more attached to the backlight module, and the problem that the display brightness of a display screen is not uniform due to bounce of the flexible panel is effectively solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible circuit board of a display screen. Background technique [0002] In addition to being connected to the display module, the flexible circuit board in the display module is also bent and fixed to the back of the display screen according to assembly requirements. When the flexible circuit is bent 180 degrees to the reverse side of the display, the rebound height of the flexible circuit is greater than the gap between the backlight and the iron shell covered by the backlight surface, which affects the structure of the backlight, further causing uneven brightness of the display and affecting the display effect. Contents of the invention [0003] In view of the above problems, the present invention provides a structure of a flexible circuit board of a display screen, which aims to solve the problem in the prior art that the display device has uneven display brightness due...
