Introduction

As a window for human-computer interaction, display devices have made great progress during the period of rapid development of information technology. Currently, popular display technologies are liquid crystal display, light-emitting diode and laser display, and OLED, as a rising star, has the greatest development potential. As people's requirements for displays increase, display testing becomes particularly important. Based on this, LCD, which has the largest market share, and OLED, which has the greatest development potential, are selected as the research objects by the experiment, in which LCD and OLED optoelectronic characteristic testing experiments are developed to help students understand the testing and evaluation methods of displays. The testing conforms to international standards and also highlights the respective characteristics as the advantages and disadvantages of LCD and OLED.
