Title:
DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2018/027450
Kind Code:
A1
Abstract:
A display screen, comprising a glass substrate; said display screen further comprising: a first electrode plate, located on a surface of the glass substrate, and a second electrode plate, located on a lower portion of the glass substrate, the first and second electrode plates forming a capacitor, wherein a gap having a pre-determined width exists between the first and second electrode plates, such that the first electrode plate elastically deforms when the display screen is subjected to external pressure; a controller, which is connected to the first electrode plate and is used to calculate a changed capacitance according to a change in the distance between the first and second electrode plates when the display screen is subjected to external pressure; and calculating a pressure value according to the changed capacitance. By configuring the first electrode plate as an electrode material on the substrate, the materials involved in providing a pressure sensor alone can be saved, and as the electrode material is made on the substrate in the form of coating film or printing, thus minimizing the thickness of the display screen.
