Slit Grating Type Oled Free Stereoscopic Display Design Research

The room we live in is a three-dimensional space. In the space we can feel the information which is also three-dimensional. So if we want to restore the world in the flat two-dimensional display, it could not do without the three-dimensional display technology. How to maximize the function of the stereoscopic display technology is the main content what the most scientists should study. Display information could not be separated with the display. With the development of today display technology, flat panel displays become more and more popular with the most people. From the research and commercial popularization, the organic light-emitting display (OLED) is becoming the current focus of the display field. OLED display is an all-solid-state semiconductor light emitting devices, it has many unparalleled characteristics that other display devices do not have, such as:self-luminous, high brightness, low power consumption, and a broad perspective. Thus three-dimensional display applications on the new OLED displays have a certain scientific research and practical significance.The article starts from the principle of three-dimensional display and OLED display technology. First, it explained the generation of the stereoscopic vision and how to get stereoscopic vision from binocular stereo images; then it introduced two kind of three-dimensional display technology based on parallax barrier. It focuses on two key points:one is the design of the OLED driver circuit, and the other is the design of the parallax barrier. It applied related technologies to design and an OLED auto stereoscopic display based on parallax barrier finally.The system mainly includes three parts:the design of OLED display driver circuit, the design of autostereoscopic display based on parallax barrier, and the acquisition and synthesis of parallax images. In the first task, the system gets AMOLED from CMEL Co., LTD as the display part and S3C2410A as the main processor. In the second task, use Matlab software to make barrier model. In the last task, use software and camera to obtain the binocular images, and get composite images by special algorithm. Finally, the system has achieved a better visual effect and some practical value.
