Data Line Shielding for Electronic Device Displays With Touch Sensors - A simplified explanation of the abstract

This abstract first appeared for US patent application 18323659 titled 'Data Line Shielding for Electronic Device Displays With Touch Sensors

Simplified Explanation

The patent application describes an electronic device with a display that has touch sensors. The display includes transistors with gate conductors, and there are one or more shielding layers between the display and the touch sensors. The display also has planarization layers, source-drain layers, and data lines. A data line shielding structure is formed in one of the source-drain layers within the planarization layers.

• The electronic device has a display with touch sensors.
• Shielding layers are placed between the display and touch sensors.
• The display includes transistors with gate conductors.
• Planarization layers are formed over the gate conductors.
• Contacts are formed in a source-drain layer within the first planarization layer.
• Data lines are formed in a source-drain layer within the second planarization layer.
• A data line shielding structure is formed in a source-drain layer within the third planarization layer.

Potential applications of this technology:

• Mobile phones and tablets: The technology can be used to improve the touch sensitivity and accuracy of the displays in mobile devices.
• Gaming consoles: The touch sensors and shielding layers can enhance the gaming experience by providing precise and responsive touch controls.
• Automotive displays: The technology can be implemented in car infotainment systems to improve touch functionality and reduce interference from external sources.

Problems solved by this technology:

• Interference reduction: The shielding layers help minimize interference between the display and touch sensors, resulting in more accurate touch detection.
• Improved touch sensitivity: The use of planarization layers and shielding structures enhances the sensitivity of the touch sensors, allowing for more precise touch input.

Benefits of this technology:

• Enhanced user experience: The improved touch sensitivity and accuracy provide users with a more seamless and responsive interaction with the electronic device.
• Reduced interference: The shielding layers help eliminate interference from external sources, ensuring reliable touch detection.
• Versatile applications: The technology can be implemented in various electronic devices, expanding its potential applications.

Original Abstract Submitted

An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The display may include transistors with gate conductors, a first planarization layer formed over the gate conductors, one or more contacts formed in a first source-drain layer within the first planarization layer, a second planarization layer formed on the first planarization layer, one or more data lines formed in a second source-drain layer within the second planarization layer, a third planarization layer formed on the second planarization layer, and a data line shielding structure formed at least partly in a third source-drain layer within the third planarization layer. The data line shielding structure may be a routing line, a blanket layer, a mesh layer formed in one or more metal layers, and/or a data line covering another data line.
