| 摘 要： | 动态图像的显示质量是平板显示器的一个重要指标,通过讨论液晶显示器和等离子体显示器不同的性能参数,提出了一种能够精确采集多种灰度条件下的响应曲线的电路设计方案并通过PSPICE模拟对其进行了验证.为了将测量的结果与人眼感知的亮度相互对应,采用标准的亮度计对采集电路的输出进行了校准,并进而得出了被测PDP最高亮度时的荧光粉响应曲线.实验证明该电路在精确度、带宽和信噪比等方面符合采集系统的要求.

| Abstract: | The display quality of dynamic images is one of the most important characteristics for FPD.The performances of LCD and PDP are discussed separately.A measurement circuit is proposed for the acquisition of luminance step response curve based on different parameters of LCD and PDP individually.The circuit has been designed through the simulation with PSPICE.In order to compare the output voltage and the actual luminance directly,the output voltage of the circuit is calibrated with the help of a standard illuminometer.And then,we obtain the phosphor response curves of the PDP on testing when the grayscale is set to 255.The test results proved that the performance of circuit met the requirement on accuracy,bandwidth and SNR. |
