Abstract

The invention discloses a display device and a preparation method thereof. The method comprises the following steps: providing a display panel which comprises an array substrate and is divided into a first region and a second region, wherein the second region and the surface of the array substrate are provided with bonding terminals; providing a driving element, and bonding the driving element on the bonding terminal; forming an ink layer on the array substrate and the driving element in the second area through an ink-jet printing technology, wherein the surface of the ink layer is flush with the surface of the first area of the display panel; and providing a polaroid, and attaching the polaroid to the display panel and the ink layer. The ink-jet printing technology is used to form the ink layer on the bonding element, the method is simple in technology, the difficulty of achieving the frameless display panel is greatly reduced, and the industrialization value is high.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a manufacturing method thereof. Background technique [0002] At present, the preparation process of the display panel in the module section process is usually: attaching a polarizer on the display panel; bonding COF (Chip On Film, chip-on-film); bonding PCB (Printed Circuit Board, printed circuit board); and side seals. However, since the bonded COF will be exposed on the upper surface of the display, the customer needs to add a lower frame to cover the COF when designing the whole device, so that the whole device cannot be flat. [0003] Therefore, there is an urgent need to develop a simple and mass-producible process technology to cover the bonded COF to achieve the borderless requirement of the display panel. Contents of the invention [0004] Embodiments of the present application provide a display device and a manufacturing method thereo...
