[0023] The functions of the layered structures of the present utility model are as follows:

[0024] 1. Hardening protection layer: A silicon dioxide coating with a relatively high hardness is used, with a thickness of about 2 - 5 microns, which can withstand friction and scratches during daily use and protect the panel surface.

[0025] 2. Anti-fingerprint layer: Composed of a fluoropolymer coating, with a thickness of about 0.1 - 0.5 microns, having a low surface energy, making fingerprints and grease not easily adhere and being easy to wipe clean.

[0026] 3. Blue light blocking layer: Formed by uniformly dispersing nano-scale organic dye particles in a polymer matrix, with a thickness of about 1 - 3 microns, which can absorb blue light with a wavelength of 400 - 480 nanometers.

[0027] 4. Touch sensing layer: Adopts a capacitive touch structure, made of indium tin oxide (ITO) conductive film, and senses touch actions by detecting capacitance changes, with a thickness of about 0.1 - 0.3 microns.

[0028] 5. Bonding layer: Uses optically transparent adhesive (OCA), with a thickness of about 20 - 50 microns, to tightly bond the touch sensing layer and the display layer together, ensuring good optical properties and bonding strength.

[0029] 6. Display layer: Adopts an OLED display structure, composed of an organic light-emitting material layer, an electrode layer, etc., which can emit light by itself, providing high contrast and vivid colors, with a thickness of about 0.2 - 0.5 millimeters.

The control system processes the received signals to achieve corresponding operations, such as clicking, swiping, zooming, etc. The display layer presents clear and vivid images according to the image signals output by the device, through the arrangement change of liquid crystal molecules (for liquid crystal display) or the light emission of light-emitting diodes (for OLED or quantum dot display). The blue light blocking layer reduces the amount of blue light entering the human eye by absorbing or reflecting blue light of specific wavelengths, playing a role in protecting the eyes. The anti-fingerprint layer, due to its special surface properties, makes fingerprints not easily adhere or easily wiped off. The hardening protection layer prevents external objects from scratching and damaging the panel surface. The thermal insulation layer reduces the incoming external heat and the internal heat dissipation, keeping the device working within a suitable temperature range.

[0036] 3. Fabrication of the display layer: Sequentially deposit the organic light-emitting material layer, electrode layer, etc. required for OLED display on the thermal insulation layer through processes such as vacuum evaporation and sputtering.

[0037] 4. Application of the bonding layer: Uniformly coat optical clear adhesive (OCA) on the display layer.

[0038] 5. Preparation of the touch sensing layer: Form an ITO conductive film on the bonding layer through sputtering or printing processes to constitute the touch sensing layer, and perform patterning treatment.

[0039] 6. Fabrication of the blue light blocking layer: Coat a polymer solution containing nano-scale organic dye particles on the touch sensing layer by spin coating or spraying, and form the blue light blocking layer after drying.

[0040] 7. Application of the anti-fingerprint layer: A fluorine-containing polymer coating is deposited on the blue light blocking layer by means of vapor deposition or dip coating to form the anti-fingerprint layer.
