Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display device for preventing IC chip failure. Background Technology

[0002] Traditional display devices include a FOG module and a backlight module. The FOG module includes an IC chip and a glass ribbon cable electrically connected to the IC chip. The backlight module includes a light strip and a lower frame. The light strip is fixedly connected to the lower frame, and the side where the light strip is located is defined as the light-incident side. The IC chip and the glass ribbon cable are respectively located on the light-incident side. When the light strip is used for a long time, it will continuously generate heat. Since the IC chip is located on the light-incident side, the high temperature caused by the continuous heat of the light strip can easily lead to IC chip failure, thereby affecting the normal display effect of the display device and the stable operation of the car driving system. This not only affects the driver's comfort experience during car driving, but also affects the driver's safety. Utility Model Content
