MERGED FLOATING PIXELS IN A TOUCH SCREEN - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240134479 titled 'MERGED FLOATING PIXELS IN A TOUCH SCREEN

Simplified Explanation

The patent application discusses touch sensor panel configurations aimed at reducing wobble error for a stylus moving over and between electrodes on the panel. Some examples include electrodes with more linear signal profiles correlating with lower wobble error, as well as diffusing elements made of floating segments of conductive materials that can diffuse signals from the stylus to multiple electrodes, improving signal profiles and optical uniformity of the panel.

• Electrodes with linear signal profiles correlated with lower wobble error
• Diffusing elements made of floating conductive segments improve signal diffusion and optical uniformity
• Diffusing elements can be formed on the same layer as floating dummy pixels, resembling merged floating dummy pixels

Original Abstract Submitted

touch sensor panel configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of the touch sensor panel are disclosed. in some examples, electrodes with more linear signal profiles are correlated with lower wobble error. in some examples, diffusing elements formed of floating segments of conductive materials can diffuse signal from a stylus to a plurality of electrodes, thus, making the signal profiles associated with the electrodes more linear. in addition, diffusing elements can be configured to improve the optical uniformity of the touch sensor panel. in some examples, the diffusing elements can be formed on the same layer as floating dummy pixels and resemble a plurality of merged floating dummy pixels.
