This paper presents a microcomputer-controlled liquid crystal display (LCD) speedometer with a digital seven-segment display where the response times is improved by a new driving technique employing phase control. According to this driving scheme, the rise and fall times have improved 60 percent and 40 percent as compared with the conventional driving scheme, respectively. A microcomputer controls optimum phase shift of complex timing signals at each temperature, and as a result, the digital LCD provides excellent readability because of the equal rise and fall times.
