Abstract

The embodiment of the invention discloses a display panel and a preparation method thereof. In the embodiment of the present invention, the display panel includes a binding area, the binding area includes an insulating layer, and a first metal layer and a chip-on-chip stacked on the insulating layer in sequence, and the non-display area also includes a conductive Medium, the conductive medium is located between the insulating layer and the first metal layer, and between the first metal layer and the chip-on-chip film, since the conductive medium wraps the upper and lower surfaces of the terminal, the bonding is increased A certain contact area improves the bonding strength and reduces the risk of peeling between the conductive medium and the terminal, thereby improving the quality and life of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] Existing flat panel display devices on the market include liquid crystal display devices (Liquid Crystal Display, LCD) and active-matrix organic light emitting diode (Active-matrix organic light emitting diode, AMOLED) display devices. [0003] Existing flat panel display devices generally include a display panel (Panel) and an external circuit. When the display panel is normally displayed, an external circuit is required, such as a flexible circuit board (Free Pascal Compiler, FPC), or a chip-on-film (ChipOn Film, COF ), and the electrical connection between the external circuit and the display panel is completed through a bonding (Bonding) process. The display panel is first bound to the chip-on-chip film, and then connected to the flexible circuit board through the chip-on-chip film, so as to real...
