一种采用多片垂直偏转板、带有水平方向偏转电极的新型扁平阴极射线管(FCRT)。有关 FCRT的基础部分的概念和实验模型加以了说明。通过实验和计算研究了模型的静电特性。如果在两片连续的垂直偏转板上依次施加适当的聚焦电压和偏转电压,在垂直扫描过程中,垂直方向的束点尺寸未发生变化。如果在水平方向的偏转电极上施加适当的偏转电压,水平方向的束点尺寸减小。电子束偏转的计算结果表明与测试的结果相符。
A new flat cathode ray tube (FCRT) with multiple vertical deflection plates and horizontal deflection electrodes. The basic concepts and experimental models for the FCRT are illustrated. The static characteristics of the model were studied experimentally and computationally. If the appropriate focus voltage and deflection voltage are sequentially applied on two continuous vertical deflection plates, the vertical spot size does not change during vertical scanning. If a suitable deflection voltage is applied to the horizontal deflection electrodes, the beam spot size in the horizontal direction is reduced. The electron beam deflection calculation results show that the results of the test are consistent.
