Transparent effect on the gray scale perception of a transparent OLED display

Area of Science:

• Visual Perception
• Display Technology
• Human-Computer Interaction

Background:

• Transparent OLED displays offer unique visual properties.
• Understanding gray scale perception is crucial for display optimization.
• Existing tone curves may not account for transparency effects.

Purpose of the Study:

• To investigate the impact of transparent OLEDs on gray scale perception.
• To quantify the 'transparent effect' in visual stimuli.
• To develop and validate a new tone curve for transparent displays.

Main Methods:

• Comparing luminance differences between transparent and non-transparent gray stimuli.
• Experimentally determining the range of the transparent effect.
• Proposing a novel tone curve derived from the transparent effect.
• Conducting a preference experiment with human participants.

Main Results:

• The transparent effect was observed in gray scale perception.
• The range of this effect was experimentally defined.
• The proposed tone curve, based on the transparent effect, received higher preference scores.
• Participants favored the new tone curve in preference tests.

Conclusions:

• The transparent effect significantly influences gray scale perception on OLED displays.
• The developed tone curve is effective and practically applicable.
• This research validates the transparent effect for real-world display applications.
