DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18120025 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a sub-pixel design for a display device that includes a transistor, a light emitting part, and a capacitor. The capacitor has two overlapping electrodes with an insulating layer in between.
- The sub-pixel design includes a first transistor with a gate electrode, a first terminal connected to a power line, and a second terminal connected to a node.
- A light emitting part, which includes at least one light emitting element, is connected to the second node and a power line.
- A capacitor is formed between the first and second nodes, consisting of a first capacitor electrode and a second capacitor electrode.
- The second capacitor electrode has a protrusion that extends further in one direction than the edge of the first capacitor electrode.
- Additionally, the second capacitor electrode has a protrusion that extends further in the opposite direction from a portion of its edge.
Potential applications of this technology:
- Display devices such as televisions, computer monitors, and mobile device screens.
- Virtual reality and augmented reality headsets.
- Automotive displays and infotainment systems.
Problems solved by this technology:
- Improved display quality and resolution.
- Enhanced power efficiency and performance of display devices.
- Reduction of artifacts such as pixelation and ghosting.
Benefits of this technology:
- Higher pixel density and sharper image quality.
- Lower power consumption and longer battery life for portable devices.
- Improved visual experience for users with enhanced color accuracy and contrast.
Original Abstract Submitted
A sub-pixel of a display device includes: a first transistor including a gate electrode connected to a first node, a first terminal connected to a first power line, and a second terminal connected to a second node; a light emitting part connected to the second node and a second power line and including at least one light emitting element; and a capacitor formed between the first and second nodes. The capacitor includes a first capacitor electrode, and a second capacitor electrode overlapping the first capacitor electrode with an insulating layer interposed therebetween in a plan view. The second capacitor electrode includes a first protrusion part protruding further in an extending direction than an edge of the first capacitor electrode, and a second protrusion part protruding further in a direction opposite to the extending direction from a portion of an edge of the second capacitor electrode in a plan view.
