    Abstract: A touch sensing structure with improved illumination includes a first substrate, a decoration layer, a light-shielding layer, a light-emitting element, a pressure-sensitive element, a first reflective layer, and a second reflective layer. The pressure-sensitive element is farther away than the light-emitting element from the first substrate. The decoration layer shows a function icon. The light-emitting element emits light to illuminate the function icon. When the first substrate is pressed, the touch sensing structure determines a magnitude of the pressing force by detecting a change in the resistance or voltage value of the pressure-sensitive element. If the pressing force reaches a specific value, the function identified by the function icon is executed, otherwise no function is executed.
