【摘要】：为了提高裸眼3D显示的光学膜层与显示屏的贴合效率和全局对位精度,提出了一种全局的、高效率的、实时的3D显示光学特性测量方案,并开发出了相应的测量系统,实现了对3D显示屏幕的亮度均匀性和串扰率均匀性的实时测量。设计并开发了测量系统的光电二极管阵列,制作了高灵敏度和高精度的电路控制模块,同时编写了上位机软件,用以实时显示数据结果。光电二极管的光谱响应与人眼光谱响应基本一致,经过标定和方向性校正后,可以实时得到屏幕不同局部在视区中的光强分布数据。基于这一数据,可以计算出屏幕不同局部定量化的串扰率数据。在实验中,测试系统能够有效测量23.7cm宽度范围内的空间光强分布,覆盖了一对左右眼视区。系统的测量精度为1.58mlx。实验表明,所得的数值结果能够定量化地反映人眼亮度和串扰率视觉感受,可用于实时检测3D显示器的视区光强分布,计算串扰率分布,有助于提高3D裸眼显示设备的装机效率。
[Abstract]:In order to improve the matching efficiency and global alignment accuracy of the optical film layer and the display screen, a global, efficient and real-time measurement scheme of optical properties of 3D display is proposed. The corresponding measurement system is developed to realize the real-time measurement of the brightness uniformity and crosstalk uniformity of 3D display screen, and the photodiode array of the measurement system is designed and developed. The circuit control module with high sensitivity and precision is made, and the upper computer software is written to display the data results in real time. The spectral response of photodiode is basically consistent with the spectral response of human eyes. After calibration and directionality correction, the light intensity distribution data of different parts of the screen in the view area can be obtained in real time. Based on this data, the crosstalk rate data of different parts of the screen can be calculated. The measuring system can effectively measure the spatial light intensity distribution in the width range of 23.7cm, covering a pair of left and right eye visual areas. The measuring accuracy of the system is 1.58mlx. The numerical results can quantitatively reflect the visual perception of human eye brightness and crosstalk rate, and can be used to real-time detect the intensity distribution of 3D display and calculate the crosstalk rate distribution. It is helpful to improve the efficiency of 3 D naked eye display equipment.
