This paper introduces the display principle of LCD by combining a singlechip(MC68HC05SR3,MOTOROLA)with a lattice liquid crystal display controller T6963C.
In view of the characteristics of liquid crystal display controller T6963CFG from TOSH1BA company and HS240128 display,the application of image LCD in embedded system is introduced.
When using LCD, suitable liquid crystal display controller should be chosen. Based on the analysis of several dot matrix liquid, crystal graphic display controller-SED1520, HD61202U, T6963C, SED1335, HD61830, their similarities, differences and apply area is pointed out through comparation.
The paper introduces the principle and application of liquid display controller SED1330 newly made by SEIKO EPSON,puts special stress on studying realization of Chinese characters display technology under graphic mode,write the concrete and practical program code,and applies it to display graph and Chinese characters in medical system,its effect is very good.
The characteristic of dot matrix graphical LCD controller T6963C is presented and the function of each pins of the chip and conjunction are showed. Else, the controlling com
In this paper, the features and composition of Dot Matrix LCD, and the working principles when it is used as a computer display terminal are analyzed. The design and working principle of LCD controller are studied with moore emphasis, the function and working process of it's every part are discussed in detail.
Based upon the display standards of IBM-PC CGA and the principle of thin film transistor(TFT ) active matrix(AM ) liquid crystal display(LCD),a control module including the circuits of LCD controller(LCDC) and encoding cir-cuit et.al .are designed , which operats as CGA model and is able to replace CRT monitor in personal computer.
