Description
Summary:碩士 === 國立交通大學 === 電機學院電子與光電學程 === 103 === In the thin film transistor liquid crystal display (thin-film transistor liquid-crystal display, referred to as TFT-LCD) drive system , the gate drive circuit , gate drivers (or said scan driver circuit, scan drivers) , is mainly responsible for a column on the screen The transistors are sequentially turned on , so that data can be entered into the liquid crystal voltage and the storage capacitor. Recently, in consumer products, the gate drive circuit has a high degree of integration in the lower part of the glass substrate, rather than the traditional use of IC chip type. and reducing the cost associated with the LCD module slimmer , Also the original a-Si production line can be used to import and transition into the IGZO material can produce higher-resolution products. This paper proposes two main circuit patterns (DMUX 1 and DMUX 2) , two types of circuits are aimed at saving layout of the space , so IGZO products in border design can be more competitive, DMUX 1 is the use of a pre-charge circuit to increase the ability to achieve a single-stage multi-output function , and the use of the protection circuit DMUX 2 from a set of multi-level Noise shared space-saving layout design concept of the two circuits can be applied at all GOA on the circuit, after a slight change to the layout to save space, and does not change the design concept of the original circuit, after the actual layout simulation and layout can really save space and also successfully design in 6.8 "WQXGA panel, circuit output quality with no difference between the original circuit , then through RA validation will be used in the products.
