Mura defects seriously affect the image quality of
products, resulting in low product yield and reduced profitability. With
increasingly end customer stringent requirements on the image quality of OLED
products and the continuous improvement of the OLED manufacturing process, the
application of DEMURA equipment for repairing mura defects has become an
important quality control method for brand manufacturers.
TZTEK's De-mura equipment adopts an innovative
detection technology and image processing algorithm to effectively remove moiré
and other optical interferences, and output high-precision pixel-level luminance data, which can be applied well after the OTP process
of OLED panels, so as to effectively reduce uneven luminance. The luminance difference after compensation is less than 1 nit, and
the compensation yield is ≥98%.
1.TZTEK’s independently developed visual algorithm is
adopted for pixel-level positioning, grayscale extraction, and other analysis,
and matches the IC to complete the Demura process.
2.De-mura compensation yield exceeds 98%; the luminance difference between mura and normal zones after
compensation is at 1 nit level.
3.Strong universality, suitable for special-shaped
screens, flexible screens, and various IC models.
4.Compatible panel size 3 - 8 inch
