Touch device comprising pressure-sensing layer and flat touch sensing layer

A touch device, comprising:

• a pressure-sensing layer configured to detect touch strength, wherein:
• the pressure-sensing layer comprises at least one radial pressure-sensing electrode,
• the radial pressure-sensing electrode has a plurality of extension portions, and
• each of the plurality of extension portions is presented as a radial pattern outwards from a center of the radial pressure-sensing electrode;
• and
• a display panel, wherein:
• the display panel is composed at least by a polarizer, an upper substrate, a color filter set, a liquid-crystal layer, a driver layer and a bottom substrate from top to bottom, and
• the pressure-sensing layer is embedded in the display panel between the polarizer and the upper substrate.

A touch device, comprising:

• a protection cover, used as an outer protection shield, an upper surface of the protection cover provided to users for a pressing action;
• a pressure-sensing layer, disposed under the protection cover, configured to detect touch strength;
• a flat touch-sensing electrode layer, disposed between the pressure-sensing layer and the protection cover, configured to detect position of the pressing action, wherein the flat touch-sensing electrode layer is disposed directly on a bottom surface of the protection cover;
• and
• a display panel, wherein:
• the display panel is composed at least by a polarizer, an upper substrate, a color filter set, a liquid-crystal layer, a driver layer and a bottom substrate from top to bottom, and
• the pressure-sensing layer is embedded in the display panel between the upper substrate and color filter set.
