Embodiment Construction

[0040] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

The present application discloses a display module, a manufacturing method of the display module, and a display device. The display module includes a display panel, an adapter flexible circuit board, a drive module, and a main flexible circuit board; the display panel is divided into a display area and a non- The display area, the non-display area includes a binding area, the binding area is provided with m rows of first pads, the transfer flexible circuit board includes m first flexible circuit boards, and one of the first flexible circuit boards The board is correspondingly bound and electrically connected to a row of the first pads, and along the direction perpendicular to the plane where the array substrate is located, the m first flexible circuit boards are sequentially stacked; the driving module includes a driving chip and For COG glass, m rows of second pads are arranged on the surface of the same side of the COG glass bound with the driver chip, and one of the first flexible circuit boards is electrically connected to a row of the second pads; The reliability of the transfer flexible circuit board binding process can be guaranteed, and it is beneficial to the narrow frame design of the display module.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module, a method for manufacturing the display module, and a display device. Background technique [0002] With the development of consumer electronic devices in terms of thinness, narrow bezels, high resolution, and high screen-to-body ratio, the size of the lower frame of the display module is required to be smaller and smaller, and the integrated circuit chip is bound to the glass (COG, Chip On Glass) ) is a technology used more in current display modules, but this kind of direct binding of integrated circuit chips (IC) on the glass of the display panel will occupy the non-display area of ​​the display panel, which is not conducive to the realization of narrow LCD panels. Border full screen design. In order to overcome this, the integrated circuit chip (IC) and the main flexible circuit board are first bound on the transfer glass, and then the signal is t...
