Problems solved by technology

[0006] The technical problem to be solved by the present invention is: currently, when designing the fan-out structure, only the influence of the uneven distribution of the resistance on the display effect is considered, and the influence of the uneven distribution of the capacitance on the display effect is not considered; in addition, in the prior art There is no overlap between the fan-out lines of the fan-out structure, resulting in an increase in the overall height of the fan-out structure, which is not conducive to the narrow frame of the LCD panel

Abstract

The invention discloses a fanout structure and an electronic device. First fanout lines and second fanout lines of the fanout structure are located on different metal layers respectively, and vertical projections of the first fanout lines on a second metal layer are partially overlapped with the second fanout lines, so that capacitance is formed between the first fanout lines and the second fanout lines. With the adoption of the fanout structure, frame narrowing of the electronic device is facilitated on the basis that the display effect of a display panel is significantly improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a fan-out structure, and also to an electronic device with the fan-out structure. Background technique [0002] The liquid crystal display panel is an important component of the liquid crystal display device. With the cooperation of the backlight module and the drive of the driving circuit, the liquid crystal display panel can display images. [0003] Usually, a TFT (Thin Film Transistor) array area is provided on the array substrate of the liquid crystal display panel. The TFT array area is covered with signal lines and TFTs. The driving circuit board connects the signal lines of the array substrate with the welding pins of the driving circuit board through a fan-out structure having a plurality of fan-out lines (FanoutLine). Generally speaking, since the solder pins are closely arranged and the signal lines are scattered (that is, the distances from the solder pins t...
