“…The first display was invented in 1897 by Karl Ferdinand Braun, a physicist, and inventor using Cathode-Ray Tube. However, before becoming a popular and comprehensive device as of today, it had taken decades of research and innovation in technology [3]. Since then, the display screen has changed the way information is absorbed.…”

Since the end of 2019, COVID-19 has left several impacts on people's life. To reduce the chance of infection, avoiding crowded places has been recommended by the authority. It raises a need to find an effective way to avoid high occupancy levels inside public places. One approach is using a screen located outside to display the occupancy information. This study aims to examine this method's effect and screen size on people's attention. To evaluate, various screen sizes were investigated in a natural arrangement meaning that people's activities and behaviors are observed and captured. The results show that placing a monitor outside is a sufficient way to inform customers about the occupancy's level; and the larger screen size increases the chance of getting people's attention. The research questions are implied in the sentence above. Our findings benefit those seeking a suitable solution to provide the occupancy level of the public places.

“…Karl Ferdinand Braun, a Nobel Prize-winning physicist, and inventor designed the first Cathode Ray Tube in 1897. High-speed electrons are emitted by the electron gun, and their deflection angle is controlled by vertical and horizontal deflection coils [1]. The high-speed electrons finally strike the screen, causing it to glow.…”

People's demand for lighting and display is gradually increasing as society and technology progress. Therefore, the scientific community has been eager to find a new kind of luminescent material suitable for industrial society. The effort paid off, as scientists discovered light conversion and its efficient Organic Light Emitting Diode materials through experiments. These materials can be divided into three distinct generations as a result of continuous updating and iteration: the first-gen (first generation) of fluorescent materials, the second- gen of phosphorescent materials, and the third-gen of TADF. In order to let the public better understand the development history of OLED materials, this paper will focus on the mechanism of different materials to discuss the schemes and introduce some of the latest applications of these materials. At the end of this review, it will illustrate why TADF the third generation of OLED light emitting material is the most promising in terms of practical applications compared with other materials and the vision of the future of OLED.
