  • Mounting film for liquid crystal display drive chip and method for manufacturing the same
    Patent number: 7746439
    Abstract: The present invention provides a mounting film for a liquid crystal display drive chip and a method for manufacturing the same. The mounting film is provided with a slit cut from a side edge thereof, or provided with a weakened line for forming the slit. When a distance between a liquid crystal display panel and a control circuit substrate of the liquid crystal display unit is un-uniform, the opening degree of the slit is variable accordingly to accommodate variations in the distance. Such a COF mounting film for a liquid crystal display drive chip may be generally used even though a distance between the liquid crystal display panel and the control circuit substrate varies slightly. Therefore, the manufacturing cost of the liquid crystal display unit may be reduced.
