Unit cell thin film glass manufactured by means of glass cutting and post-processing method

Thin glass in cell unit (4) installed on the front surface of an electronic device or a display unit of an electronic device,

• wherein the thin glass in cell unit (4) is manufactured by glass cutting and post-processing methods, wherein:
• a bevel-shaped cut portion (41) is formed at an end of one side of the thin glass in cell unit (4) in contact with the front surface of the display unit;
• and
• the tilt angle of a side portion(S) of the thin glass in cell unit (4) is 85 degrees to 95 degrees with respect to a horizontal surface, and
• the glass cutting and post-processing methods include:
• (S1) coating one side of thin mother glass (1) with a coating solution for preventing chemical contact in order to proceed with selective chemical treatment;
• (S2) drying the coating solution to form a coating film (2) on one side of the thin mother glass (1);
• (S3) cutting the thin mother glass (1) to obtain thin glass in cell unit (4), which is applied to an electronic device or a display unit of an electronic device, from the thin mother glass (1);
• (S4) healing a cut surface of the thin glass in cell unit (4) through performing selective chemical treatment on the cut thin glass in cell unit (4) in order to remove a thermally-damaged area and a defective area generated around the cut surface of the thin glass in cell unit (4) during the cutting process;
• (S5) ablating the coating film (2) of the thin glass in cell unit (4);
• and
• (S6) chemically healing a surface of the thin glass in cell unit (4), from which the coating film (2) has been ablated, in order to remove a defect or a flaw on the surface of the thin glass in cell unit (4) from which the coating film (2) has been ablated,
• wherein
• in (S3) of the cutting of the thin mother glass (1) to obtain the thin glass in cell unit (4), which is applied to an electronic device or a display unit of an electronic device, from the thin mother glass (1), if the coating film (2) is formed only on one side of the thin mother glass (1), a surface of the thin mother glass (1) on which the coating film (2) is not formed is irradiated with a laser beam output from an infrared laser (3) generating a wavelength of 1000 nm or greater to cut the thin mother glass (1) and the coating film (2), wherein:
• a nanosecond infrared laser (3), a picosecond infrared laser (3), or a femtosecond infrared laser (3) is used as the infrared laser (3);
• and
• the infrared laser (3) outputs a Bessel beam, and
• in (S4) of the healing a cut surface of the thin glass in cell unit (4) through performing selective chemical treatment on the cut thin glass in cell unit (4) in order to remove a thermally-damaged area and a defective area generated around the cut surface of the thin glass in cell unit (4) during the cutting process, a bevel-shaped cut portion (41) is formed at an end of one side of the thin glass in cell unit (4) in contact with the coating film (2) by using a healing solution, and the laser beam (3) outputting a Bessel beam has a laser beam wavelength of 1020 nm to 1040 nm,
• the thin glass in cell unit (4) is bent toward the front of the display unit.
