DISPLAY DEVICE AND INSPECTION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18469768 titled 'DISPLAY DEVICE AND INSPECTION METHOD THEREOF
Simplified Explanation:
The patent application describes a display device that includes a touch panel and a display panel. The touch panel outputs touch sensing signals, and at least one of these signals is converted from a time domain to a frequency domain to detect information on the thickness of a common electrode without damaging the device.
- The touch panel of the display device outputs touch sensing signals.
- One or more touch sensing signals are converted from a time domain to a frequency domain.
- Information on the thickness of a common electrode is detected based on the peak of the converted touch sensing signal.
- This allows inspection of the uniformity of the common electrode thickness without causing damage to the display device.
Potential Applications:
This technology could be applied in various industries such as consumer electronics, automotive displays, medical devices, and industrial control panels.

Original Abstract Submitted
A display device includes a touch panel and a display panel. The touch panel outputs touch sensing signals. At least one of a plurality of touch sensing signals is converted from a time domain to a frequency domain, and then information on a thickness of a common electrode is detected based on a peak of the converted touch sensing signal. As a result, it is possible to inspect whether the common electrode is formed with a uniform thickness without destroying the display device.
