Electronic Devices Having Moisture-Insensitive Optical Touch Sensors - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18175672 Titled 'Electronic Devices Having Moisture-Insensitive Optical Touch Sensors'
Simplified Explanation
This abstract describes an electronic device with a touch-sensitive display that can still work even when it is wet or exposed to moisture. The display uses a two-dimensional optical touch sensor, which includes light sources and light detectors. These components are mounted on the same surface as the display pixels, which are made of a type of semiconductor called a light-emitting diode. The touch sensor also includes filters that help distinguish between a user's finger and water droplets, improving accuracy.
Original Abstract Submitted
An electronic device may have a touch sensitive display that is insensitive to the presence of moisture. The display may have a two-dimensional optical touch sensor that gathers touch input while the electronic device is immersed in water or otherwise exposed to moisture. The optical touch sensor may include light sources and light detectors. The light sources and the light sensors may be mounted on a common substrate with an array of image pixels. The image pixels may be formed by crystalline semiconductor light-emitting diode dies. Angular filters may be included over the light sources and/or the light detectors to improve discrimination between a user's finger and water droplets. The angular filters may be on-axis light blocking angular filters or off-axis light blocking angular filters.
