目前市場上,大尺寸液晶顯示器的需求正大幅增加,而液晶顯示器的品質好壞如果能在不增加製程費用之前提下,予以改善大尺寸液晶顯示器的亮度均勻問題,則亦即提高液晶顯示器的品質。
基於此,本文即應用框架速率控制的原理及動態輸出致能的方式,予以進行液晶顯示器驅動線路控制晶片之研發,以改善大尺寸液晶顯示器之水平及垂直亮度不均的問題。其中本文所提之驅動線路控制晶片具有微處理器、記憶體、數位電路、類比電路等功能之系統晶片整合,而其並具有電路成本降低、應用電路減少及整體系統之穩定度提升之優點。
本文並將所研製之驅動線路控制晶片予以測試,其結果應足以說明其已可有效改善亮度不均之問題,且此驅動線路控制技術並可視製程需要,進行各個控制參數大小之調整,如將其廣泛應用於液晶顯示器產業領域中,應具有節省電能開發、提升製程良率及故障率降低之特點,對於未來相關控制晶片之設計,亦具有實用參考價值。
The application of large-scaled Thin Film Transistor Liquid Crystal Display (TFT-LCD) is seen more popular nowadays, yet the problem of unequal luminance of panels is still an obstacle with the growing size of the panel. In view of such drawback, based on the use of frame rate control (FRC) and dynamic output enable concept, the thesis has proposed an integrated in anticipating of solving this problem.
In the method, the system-on-a-chip (SOC) was also developed, where the microprocessor, memory, digital circuit and analog circuit were all considered to be integrated. By which, it can both reduce the external wires and investment cost, while the stability of the system can be better maintained. It is expected that with the application of the proposed method in the TFT-LCD industry, the reduction of power consumption, the increment of yield rate, and the decrement of defect rate can be all benefited. This proposed approach also owns a practical value as the reference for the control IC design.
