DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240036672 titled 'DISPLAY DEVICE
Simplified Explanation
The abstract describes a display device that includes a light-emitting element, a pixel-defining film, a sensing electrode, a light-blocking pattern, and a color filter. The light-emitting element consists of a first electrode, a second electrode, and a light-emitting layer. The pixel-defining film has a pixel opening that exposes the first electrode and includes a sensing electrode. The sensing electrode has a light-blocking pattern and a color filter on top of it. The light-blocking pattern is composed of a first pattern part and a second pattern part, which have different optical densities with respect to first light.
- The display device includes a light-emitting element with electrodes and a light-emitting layer.
- A pixel-defining film with a pixel opening is used to expose the first electrode.
- A sensing electrode is present on the pixel-defining film.
- A light-blocking pattern is applied on the sensing electrode.
- A color filter is placed on top of the sensing electrode.
- The light-blocking pattern consists of two parts with different optical densities.
Potential applications of this technology:
- Display devices: This innovation can be used in various display devices such as televisions, computer monitors, and mobile phones.
- Virtual reality (VR) and augmented reality (AR): The display device can enhance the visual experience in VR and AR applications.
- Wearable technology: The technology can be integrated into wearable devices like smartwatches and smart glasses to provide visual information.
Problems solved by this technology:
- Improved display quality: The different optical densities of the light-blocking pattern help in achieving better contrast and color accuracy in the displayed images.
- Enhanced visual experience: The use of a pixel-defining film and a sensing electrode allows for precise control of the displayed pixels, resulting in sharper and more vibrant images.
- Reduction of light leakage: The light-blocking pattern prevents unwanted light from passing through the sensing electrode, reducing glare and improving image clarity.
Benefits of this technology:
- High image quality: The combination of the light-emitting element, pixel-defining film, and sensing electrode ensures high-resolution and high-contrast display capabilities.
- Customizable color representation: The color filter on the sensing electrode allows for accurate color reproduction and customization.
- Energy efficiency: The display device can be designed to consume less power, leading to improved energy efficiency and longer battery life in portable devices.
