Abstract

The present invention provides a display panel and a spliced ​​display panel. The display panel includes: a GOA circuit, a GOA signal bus and a chip-on-chip film area. In the present invention, the chip-on-chip film area is output from the traditional two sides, and the signal output is performed by each film chip, so as to reduce the signal difference of the GOA bus line, so that the GOA circuit received by each level of GOA circuit The signal difference is reduced as much as possible, thereby reducing the output signal difference of the GOA circuit and reducing the impact on the charging of the pixels in the display area.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a display panel with an ultra-narrow frame and a spliced ​​display panel. Background technique

[0002] In response to market demand, large-size and high-resolution displays and ultra-narrow borders (UNB: Ultra Narrow Border) have become market trends. In recent years, splicing screens, which have attracted wide attention from the market, have raised the bar for display products with extreme narrow border technology. Demand, seams are extremely reduced, and the distance between adjacent splicing panels needs to be less than 1mm has become a future trend. The GOA circuit is located on one side of the panel (GOA in Source), which has three narrow and one wide products, because it can be used for three-sided splicing, and has a non-negligible price advantage compared with existing products, which has attracted widespread attention in the industry in recent years. . Such as figur...
