Problems solved by technology

When the glass substrate is cut, the cutting knife wheel needs a certain pressure, which will cause cracks or defects on the cutting edge of the glass substrate, so that the cracks or defects extend to the top of the glass substrate for a certain distance. distance, causing the metal pad to crack or damage, thereby affecting the performance of chip bonding, resulting in poor contact conductivity between the metal pad and the chip

Abstract

The invention discloses a COG glass substrate structure and a display panel. The COG glass substrate structure comprises a glass substrate and a chip, the glass substrate comprises a cut edge, and thechip is fixed to the glass substrate and comprises a plurality of metal pads away from the cut edge of the glass substrate. Since the metal pads are arranged away from the cut edge of the glass substrate, damages of the metal pads due to cracks and incompleteness of the cut edge of the glass substrate can be reduced, and accordingly chip binding performances are improved, and contact conductivityof the metal pads and the chip is promoted.

Description

【Technical field】 [0001] The present disclosure relates to the field of display technology, in particular to a COG glass substrate structure and a display panel. 【Background technique】 [0002] In the current COG glass substrate structure, a plurality of metal pads of the chip are disposed adjacent to the cutting edge of the glass substrate. When the glass substrate is cut, the cutting knife wheel needs a certain pressure, which will cause cracks or defects on the cutting edge of the glass substrate, so that the cracks or defects extend to the top of the glass substrate for a certain distance. distance, causing the metal pad to be cracked or damaged, thereby affecting the performance of chip bonding, resulting in poor electrical conductivity between the metal pad and the chip. [0003] Therefore, it is necessary to provide a COG glass substrate structure and a display panel to solve the problems existing in the prior art. 【Content of invention】 [0004] To solve the abov...
