| dc.description.abstract | This thesis mainly discusses the improvement of optical quality and reliability of automotive liquid crystal displays. It is well known that the environmental test of automotive liquid crystal displays is more stringent than general electronic products, so the optical quality and reliability of automotive liquid crystal displays are very important requirements.
This study focuses on three research is aimed at the center console of a vehicle using a liquid crystal display. First, explore how cushioning tape can improve light leakage of the optical quality of the vehicle displays. Then, after the environmental test., how to improve optical film producing backlight Mura phenomenon and affecting the optical quality of the vehicle displays Final, after the environmental test, how to adjust the gap and fixing materials to improve the noise problem and prevent the film waving from affecting the optical quality of the vehicle display.
The light leakage phenomenon of the vehicle display of this study was tested by comparing the characteristics of the cushioning tape. After the experiment, it was found that the acrylic foam cushioning tape made the optical quality of the vehicle display more uniform. After the automobile display was placed at 90℃ for 240 hours under high temperature storage, the backlight Mura produced by scratching the prism structure in the optical film was improved, and after the experiment, it was found that the scratch was improved. The UV adhesive material is characterized by high elasticity and ductility, which effectively prevents the optical film from damaging the surface structure during the thermal expansion and contraction in the environmental test. Improve the noise problem of the car display and prevent the optical film waving. Designed by the linear expansion formula to improve the optical film to reserve the gap and fix the material with noise to facilitate the car display to be placed at 90℃ under high temperature storage. The optical film does not wave to make the optical quality of the vehicle display more uniform.
According to the above research, it is important to consider the expansion and contraction of the optical film and the prevention of abnormal sound, as well as the selection of the characteristics of the cushioning tape and the choice of the material of the optical film. These need to be considered to design a good vehicle display.
