OLED displays are generally considered to be less harmful than LED displays because they do not require a backlight, which can emit blue light that may be harmful to the eyes. OLED displays emit light directly from the individual pixels, resulting in better contrast and color accuracy. However, both OLED and LED displays can still emit blue light, which may cause eye strain and disrupt sleep patterns if used for extended periods of time. It is important to use both types of displays in moderation and take regular breaks to reduce the potential negative effects on eye health. **
