Problems solved by technology

Generally, when the brightness of the displayed image is high, even if there are obvious defects in the display device (for example, blurring due to a defect in the driver IC), blurring defects, mottle formation, etc. are not fully felt
[0006] As can be seen from the above description, since the operator's subjectivity is involved in the evaluation of the image quality of the display device, it is difficult to give an objective and fair evaluation between the manufacturer and the purchaser of the display device standard
