摘要

随着技术的进步，图像传感器可以轻松地获得高动态范围图像，而传统显示设备的显示范围只有100：1。目前采用投影仪、发光二极管阵列等双屏结构的高动态范围显示系统存在体积庞大、局部对比度低等缺点。据此提出采用场致发射背光源，利用图像分割算法，完成高动态范围图像的显示。文章提出的系统具有提高高动态范围液晶显示器的局部对比度与减淡光晕的优点，实验结果表明，文中的场致发射背光结构的局部对比度提高到近65 025：1，具有较高的实用价值。

Abstract

With the development of technology

the image sensor can easily obtained High Dynamic Range (HDR) image just as the large dynamic range of luminance values in a scene of real life

while the display range of conventional display device is only 100:1. The systems of HDR display based on the dual structure of the projector or LED array has many shortcomings

such as huge volume and low local contrast. So this paper presents a backlight of liquid crystal display using field emission backlight. HDR images have been displayed by using image segmentation algorithm. The point-by-point control mechanism of front and back panel

which divides the high dynamic image in the systems of two panels is proposed. The experiment result demonstrates that the field emission backlight structure can increase the LCD local contrast to 65 025:1. And it has higher practical value for displayer.
