Abstract

The invention belongs to the technical field of liquid crystal televisions and discloses a liquid crystal module. The liquid crystal module includes a glass panel, a middle frame, a front frame and a COF, wherein the middle frame is arranged under the glass panel, and the outer wall of the middle frame is provided with grooves; the front frame covers the outside of the glass panel and the middle frame, and Ribs are provided on the inner wall of the surface frame; one end of the COF is set on the glass panel, and the other end presses against the ribs and bends toward the groove. In the present invention, ribs are provided on the inner wall of the surface frame corresponding to the COF, and grooves are provided on the outer wall of the middle frame corresponding to the COF, so that the liquid crystal module does not need to add any limiting materials when assembling, but only uses the ribs to adjust the COF. Pressure is applied to make the COF bend towards the inside of the groove, and the relative position of the groove and the rib is used to fix it, which efficiently and concisely solves the COF bending and positioning protection, thereby realizing the design of the ultra-narrow bezel LCD module.

Description

technical field [0001] The invention relates to the technical field of liquid crystal televisions, in particular to a liquid crystal module. Background technique [0002] Due to different manufacturing processes, liquid crystal panels (open cells) can be divided into two types: Chip On Film (COF) without sides and COF with sides. COF is a flexible circuit board (Flexible Printed Circuit, FPC) containing circuits and integrated circuits (integrated circuit, IC) bonded on a glass panel, which is characterized by being bendable and easily damaged. [0003] LCD TVs have higher and higher requirements for narrow bezels, so products with ultra-narrow bezels and no bezels have emerged as the times require. However, for LCD panels with side COFs, it is very difficult to achieve ultra-narrow bezels. To achieve an ultra-narrow bezel, COF must be bent downward, and how to limit and fix COF after bending and how to protect it safely have become the focus of research and design in the i...
