Flexible Preparation Of Liquid Crystal Display Device And Control Box Of Thick Research

As an important part of electronic information industry, display technology has developed rapidly in recent years. The main two direction of development are optimization of the display quality and the improvement of the device size. From heavy CRT to flat panel display nowadays, many efforts have been made to reduce the size of display device. With the displays becoming thinner and lighter, the application of displays is also entering various areas. And now the next goal of this direction is flexible display.Using flexible glass, plastic instead of traditional glass substrate, the displays can be foldable and rollable. With the advantages in resistance, portability and low power consumption, flexible display has won the wide attention and huge market potential. Many companies and research institutes have proposed several kinds of technology to achieve flexible device. Among these technologies, liquid crystal display occupied an important position as its mature process technology, relatively simple device structure and lower costs. However, there are still many problems to solve during the fabrication of the flexible liquid crystal display (FLCD) device such as substrate processing, cell gap control and so on.In this work, plastic transparent conductive film was used as substrate to research the fabrication of FLCD cell. It was figured out a reliable process of sub-strate treatment including cutting, cleaning, annealing, etc. The research about the cell gap control started with conventional technique of spin-coating bead s-pacer. And in order to solve the problem with the bead spacer, screen printing and photo spacer were researched as method more suitable for flexible substrate. With these two techniques, the spacer patterns can be produced accurately and cell gap of FLCD cell can also be maintained accurately and stably. The coefficient of variation of the cell gap was under5%. The optical-electric characteristic was measured and the FLCD cell can be driven successfully at6V, which proved the reliability of the the fabrication process.
