Abstract

The invention provides a display panel and a frame substrate thereof. The frame substrate includes a bending area and a plurality of routing lines, each of the plurality of routing lines includes a first line area and a second line area, the first line area and the second line area are disposed on the bending area, and the width of the first line area of each of the plurality of routing lines is greater than the width of the second line area of the plurality of routing lines, and the first line areas of the adjacent routing lines are staggered from each other.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a display panel with a chip-on-film package (COF). Background technique [0002] With the increasing demand for display devices, the requirements for display appearance are getting higher and higher, especially for mobile phone display products. The smaller the size, the better the display. [0003] In order to achieve a higher screen-to-body ratio, the glass adopts a chip-on-film package (COF, Chip On Film), that is, the chip is bound on a flexible circuit board (FPC, Flexible Printed Circuit) and folded to the back of the display substrate. package, thereby reducing the occupation of the glass substrate, and can shorten the lower frame of the small-sized display module to achieve a narrow frame, however, when the film-on-chip package is in an assembled state, the film-on-chip package has a One end of the upper part is bent to be installed under the display pan...
