Patent ID: 8648850

Claim:
A method of compensating for a display defect of a flat panel display, the method comprising: reading identification information of a display panel using a barcode reader, wherein the identification information is a model identification, formed with a barcode type on the display panel, and includes the size, the resolution and the pitch between cells of the display panel; automatically generating predetermined directional data of the display defect and gray level region data of the display panel according to the identification information, wherein the directional data indicates whether the display defect appears on the display panel in a vertical direction or a horizontal direction, inputting the first information including a coordinate value indicating the position of the display defect according to the directional data; inputting the second information including defect level information indicating the degree of the display defect; generating positional information indicating the position of the display defect and the form of the display defect of the display panel on the basis of first input information and the identification information; generating a compensation value for compensating the degree of the display defect on the basis of second input information; storing the positional information and the compensation value in a memory; and reading the positional information and the compensation value from the memory, modulating data to be displayed at the position of the display defect by the compensation value, and displaying the modulated data on the display panel, wherein the display defect includes a central compensation region and gradient compensation regions, which are located at both sides of the central compensation region, positioned, wherein the number of the gradient compensation regions is adjusted according to the compensation value of the central compensation region, wherein the number of the gradient compensation regions increased as the compensation value of the central compensation region is increased and is decreased as the compensation value of the central compensation region is decreased, and wherein a width of each gradient compensation region is defined to the number of pixels divided by a multiple of 4.
