Description

Display module and display device Technical Field The utility model relates to the technical field of batteries, in particular to a display module and a display device. Background With the continuous development of optical technology and semiconductor technology, display devices are evolving towards light weight, miniaturization and high integration. This trend has driven the widespread use of new materials and new packaging technologies. The Chip On Film (COF) technology is used as a key packaging mode, and can be directly fixed On a flexible circuit board through an integrated circuit Chip and electrically connected with a display panel through a binding process, so that the high-efficiency and reliable signal transmission requirement is met, and the Chip On Film (COF) technology is widely applied to various high-resolution display products. In the actual use of the display device, when the ambient temperature changes drastically, water vapor in the air inside the display device is likely to condense on low-temperature surfaces such as metal or glass inside the display panel. Because a certain height difference exists between the driving chip and the flexible substrate in the COF structure, condensed water drops are easy to collect and stay in the concave area. The water drops may carry corrosive ions such as potassium, sodium and the like dissolved in the air in the condensation process, and the long-time retention is easy to cause corrosion damage to electrodes, wires or chips in the COF structure, so that the driving function is caused to fail, abnormal phenomena such as picture flickering, stripe interference and even black screen and the like of the display device are caused, and the stability and the user experience of the product are seriously influenced.
