DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18462522 titled 'DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

Simplified Explanation

The abstract describes a display device that includes a substrate, a gate line, a transistor, and a light-emitting element. The gate line consists of three layers: a first layer made of aluminum or an aluminum alloy, a second layer made of titanium nitride, and a third layer made of metallic titanium nitride. The metallic titanium nitride has an N/Ti molar ratio ranging from about 0.2 to about 0.75.

• The display device includes a substrate, gate line, transistor, and light-emitting element.
• The gate line is composed of three layers: aluminum or an aluminum alloy, titanium nitride, and metallic titanium nitride.
• The metallic titanium nitride has an N/Ti molar ratio between 0.2 and 0.75.

Potential Applications

This technology can be applied in various display devices, such as:

• Televisions
• Computer monitors
• Smartphones
• Tablets
• Wearable devices

Problems Solved

The display device addresses the following issues:

• Improved performance and efficiency of the gate line
• Enhanced durability and longevity of the display device
• Reduction in power consumption

Benefits

The use of the three-layer gate line in the display device offers several advantages:

• Higher conductivity and improved signal transmission
• Increased resistance to corrosion and wear
• Lower power consumption and improved energy efficiency

Original Abstract Submitted

Provided is a display device. The display device includes: a substrate; a gate line disposed on the substrate; a transistor including a part of the gate line; and a light-emitting element connected to the transistor, in which the gate line includes a first layer including aluminum or an aluminum alloy, a second layer including titanium nitride, and a third layer including metallic titanium nitride. An N/Ti molar ratio of the metallic titanium nitride may be in a range from about 0.2 to about 0.75.
