MEASURING STRAIN ON DISPLAY DEVICE

A display includes a thin-film transistor (TFT) glass layer having a top surface and a bottom surface and a color-filter glass layer having a top and a bottom surface. The TFT glass layer extends beyond the color-filter glass layer to form an overhanging portion of the TFT glass layer. The overhangi...

Beschreibung
Zusammenfassung:	A display includes a thin-film transistor (TFT) glass layer having a top surface and a bottom surface and a color-filter glass layer having a top and a bottom surface. The TFT glass layer extends beyond the color-filter glass layer to form an overhanging portion of the TFT glass layer. The overhanging portion is flexible, and a flexible printed circuit (FPC) is affixed to the overhanging portion. The FPC includes an integrated strain gauge for measuring strain at a plurality of locations on the overhanging portion of the TFT glass layer. The display device may be incorporated into a chassis to secure the display in the device. A processor, within the housing, may instruct the strain gauge to measure the strain.
