Abstract
By varying the beam current of a color CRT(cathode ray tube) monitor, the misconvergence, spot size, display luminance, and chromaticity coordinate of a white pattern were measured at 4 screen positions. The misconvergence was measured with a linear CCD (charge coupled-device). The resolution was obtained by using SQRI (square root integral) method. The misconvergence of a color monitor was not influenced by the beam current but by the screen position. The misconvergence on a screen perimeter caused the resolution to decrease.
칼라 CTR(cathode ray tube) 모니터의 빔 전류와 화면위치를 변화시키면서 misconvergence, 스폿 크기, 디스플레이 휘도, 색도 좌표를 측정하였다. 일차원 CCD(charge coupled device)를 사용하여 misconvergence를 측정하였으며, 시감효과를 고려하는 SQRI(square-root integrals)를 도입하여 분해능을 나타내었다. 모니터의 miscovergence는 빔 전류에 영향을 받지 않고 화면의 위치에 따라 변하였으며, 화면 주변부에서의 misconvergence는 분해능을 저하시켰다.
