DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18382316 titled 'DISPLAY DEVICE
Simplified Explanation
The display device described in the patent application includes a control layer that affects the transmittance of light at a specific wavelength band, particularly in the green wavelength band. This control layer is designed to decrease the front luminance spectrum more than the side luminance spectrum, resulting in improved display performance.
- The display device includes pixels with light emitting elements and a control layer that affects the transmittance of light.
- The control layer is positioned in a way that reduces front luminance more than side luminance.
- The transmittance of the control layer at the green wavelength band is lower than at other visible light regions.
Potential Applications
The technology described in the patent application could be applied in various display devices such as TVs, monitors, smartphones, and wearable devices to enhance the visual performance of the screens.
Problems Solved
This technology addresses the issue of uneven luminance distribution in display devices, ensuring a more consistent and high-quality viewing experience for users.
Benefits
The benefits of this technology include improved display performance, enhanced visual quality, and a more uniform luminance distribution across the screen.
Potential Commercial Applications
The technology could be utilized in the manufacturing of high-end display devices for consumer electronics, automotive displays, medical monitors, and other applications where visual quality is crucial.
Possible Prior Art
One possible prior art could be the use of polarizing filters in display devices to control light transmittance and improve visual performance.
What is the manufacturing process for integrating the control layer into the display device?
The manufacturing process involves depositing the control layer onto the pixels containing the light emitting elements, ensuring precise alignment and uniform coverage across the screen.
How does the control layer specifically target the green wavelength band to achieve the desired effect on luminance?
The control layer is designed with specific optical properties that selectively reduce transmittance at the green wavelength band while allowing light to pass through at other visible light regions, resulting in the desired luminance effect.
Original Abstract Submitted
A display device includes a plurality of pixels including a first pixel representing green, where each of the pixels includes a light emitting element including an anode, a light emitting layer, and a cathode. The display device further includes a control layer disposed in a direction in which the light emitting element emits light and overlapping the first pixel, and a transmittance of the control layer at a first wavelength band, within a green wavelength band, is lower than a transmittance at a remaining visible light region such that a decrease in a front luminance spectrum by the control layer is greater than a decrease in a side luminance spectrum by the control layer.
