Abstract

The invention discloses a display module and a display device. The display module comprises a display panel and a backlight module, wherein the backlight module is arranged opposite to the display panel and comprises a backlight light bar, a main flexible circuit board and a COF flexible circuit board, the COF flexible circuit board is connected with the display panel and the main flexible circuit board separately, and the COF flexible circuit board can be bent to make the main flexible circuit board arranged at the side, away from the display panel, of the backlight module; the backlight light bar is connected with the main flexible circuit board through the COF flexible circuit board. According to the display module and the display device, the backlight light bar is connected with the main flexible circuit board through the COF flexible circuit board to achieve driving control of the main flexible circuit board over the backlight light bar, the length of leads drawn forth the backlight light bar can be obviously shortened when the backlight light bar builds circuit connection, the backlight light bar is directly connected with the COF flexible circuit board near to the backlight light bar, when connection is conducted, the problem that the locating precision is hard to guarantee does not exist, and the product yield is increased.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module and a display device. Background technique [0002] With the rapid development of science and technology, electronic smart devices have become an indispensable part of people's lives. While pursuing smooth user experience and diverse functional experience, people are also constantly pursuing better visual experience, such as high contrast display devices, high screen-to-body ratio display devices, etc. Among them, one way to realize a display device with a high screen-to-body ratio is to narrow the lower frame of the display panel. An existing COF (Chip On Film, chip-on-film) technology is a technology that fixes a driver IC to a flexible circuit. On-board (Flexible Printed Circuit, FPC) chip soft film construction technology, using a soft additional circuit board as a package chip carrier to bond the chip to the flexible substrate circuit. In...
