Abstract

The invention provides a narrow-frame display panel and a display device. The narrow-frame display panel comprises a display area and a non-display area surrounding the display area. The narrow-framedisplay panel further comprises a color film substrate, an array substrate, a frame glue, a first conducting layer and a power supply circuit. In the invention, two metal wires are additionally arranged on a side of the color film substrate, on one hand, signals of a common electrode are connected into the color film substrate from a COF so that peripheral wires of the common electrode on the sideof the array substrate, needed when an existing array substrate is powered on, and conversion terminals and gold balls needed for conducting an upper substrate and a lower substrate, are removed; andon the other hand, the two metal wires are arranged in the non-display area and are connected with ITO wires so that a contact area of the metal wires and the ITO wires is increased, and purposes ofeffectively reducing a contact impedance and reducing signal voltage drop are achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel with a narrow frame and a display device. Background technique [0002] Conventional LCD cell (LCD optical film) is designed to input signals from the array substrate side (Thin Film Ttransistor, TFT), where the common electrode CF-Com signal on the color filter substrate (color filter, CF) passes through the transfer terminal (Transfer pad) The gold ball (Au ball) is transferred from the TFT board to the CF board to realize the power supply to the common electrode CF-Com. [0003] For LCD products with normal borders, the LCD has enough border (frame) space to ensure the conduction area of ​​the Transfer pad and meet the requirements of low contact impedance between the TFT board and the CF board. [0004] However, for ultra-narrow bezel LCD products, the gap between the bezels is generally less than 1 mm, and the space in the border area is narrow, w...
