Stereoscopic surface display device and operation method thereof

A manufacturing method of a stereoscopic surface display device, comprising:

• forming a light absorption layer on a carrier substrate;
• forming a preliminary polymer layer covering the light absorption layer on the carrier substrate;
• and
• forming a polymer layer by curing the preliminary polymer layer,
• wherein the curing of the preliminary polymer layer comprises irradiating the preliminary polymer layer with first light,
• the light absorption layer heats one area of the preliminary polymer layer to apply thermal stress during the curing, and
• the one area is cured to have a stereoscopic shape by the thermal stress.

An operation method of a stereoscopic surface display device comprising a light source unit and a stereoscopic display unit having a curved first cell area with a curvature,

• wherein the stereoscopic display unit comprises:
• a polymer layer;
• and
• a light absorption layer buried in the polymer layer,
• the light absorption layer comprises a first light absorption pattern disposed in the first cell area, and
• the light source unit comprises a first optical element disposed below the first cell area,
• wherein the operation method comprises:
• irradiating the first light absorption pattern with first light from the first optical element, wherein the first light absorption pattern generates thermal energy by receiving the first light;
• heating the first cell area to a first temperature by using the thermal energy;
• and
• decreasing the curvature of the first cell area by the first temperature.
