Abstract: Experiments were conducted to examine the visual display performanceof Chinese characters with ten different dot matrixes and less than twen-ty-three strokes. The experiments demonstrated that the effect of dot ma-trix on visual display performance is dependent on dot matrix size. Usingdot matrixes less than 24×24 and strokes with single dot width, Chinesecharacfer display performance increased with the size of dot matrixes andreached its optimum in the size of 24×24. The performance deterioratedwith further increase of size of dot matrix. This is because the strokewith single dot width is too narrow to display Chinese characters withreasonable quality. The result shows that the minimum dot matrix forChinese characters with more than twenty strokes is 20×20,strokes withsingle dot width is not appropriate for the dot matrix larger than 32×32.
