P‐3.1: Display Quality and Visual Fatigue Effect of LTPO and LTPS

With the daily application of mobile phones, the frequency and length of mobile phone use has increased greatly, and the research on the impact of display screens on human eye fatigue has become increasingly important. OLED screens on the market now mainly use LTPO and LTPS technologies. In order to discuss the display quality and visual comfort of these two display technologies, this paper studies the optical performance measurement and subjective evaluation. The results show that LTPO and LTPS display have good visual comfort in solid color screen. Under long‐term dynamic display, LTPO response time is shorter, residual image dissipation is faster, screen switching almost leaves no trace, animation fluency is higher, and the post‐00s and myopic people are more inclined to the visual comfort of LTPO products. The difference between LTPO and LTPS fatigue becomes smaller with age, and the difference in fatigue increases with vision.
