Abstract

A display panel can reduce cost, overheating risk and line width precision requirements, and comprises: a first substrate; a second substrate, which is arranged below the first substrate and is provided with a joint end part, and the joint end part is provided with an upper surface and a side surface which are connected with each other; a plurality of first circuits, which are arranged on the second substrate at intervals, wherein each first circuit is provided with a first joint end arranged on the upper surface; a plurality of second circuits, which are arranged on the second substrate at intervals and are separated from the first circuits, wherein each second circuit is provided with a second joint end arranged at the joint of the side surface and the upper surface; a first circuit board, which is located on the upper surface and provided with a plurality of third joint ends, wherein the third joint ends are electrically connected with the first joint ends respectively; and a second circuit board, which is positioned on the side surface and is provided with a plurality of fourth joint ends, wherein the fourth joint ends are electrically connected with the second joint ends respectively.

Description

technical field [0001] The invention relates to a display panel. Background technique [0002] The vertical gate (Vertical-gate) technology that the display panel has developed so far pulls the data (data) line and the gate (gate) line to one side of the display panel, and uses a double-layer chip on film (2-layered chip on film) ), the source driver chip and the gate driver chip are made on the double-layer chip-on-chip film, so that the border on the non-outer lead bonding side can be less than 1 mm, in order to achieve Need for ultra-narrow bezels. However, today’s vertical gate technology must use double-layer chip-on-chip films, resulting in a significant increase in the cost of the display panel, and the fine line width design required by this vertical gate technology also has doubts about the accuracy, and it will also be used for a long time. Problems that cause circuits to overheat. Contents of the invention [0003] The present invention provides a display pan...
