Abstract

The invention discloses the flat display panel, picture quality controlling apparatus and method thereof. The method of controlling a picture quality of a flat panel display device includes: storing a first compensation data used to compensate a panel defect area of a display panel, wherein the first compensation data is judged by a first inspection process, storing a second compensation data used to compensate a boundary between the panel defect area and a non-defect area of the display panel, wherein the second compensation data is judged by a second inspection process; a first compensation step to modulate data using the first compensation data stored in a memory, wherein first modulated data are supplied to the panel defect area; a second compensation step to modulate data using the second compensation data stored in the memory, wherein second modulated data are supplied to the boundary of the panel defect area and the non-defect area; and displaying the second modulated data on the display panel.

Description

[0001] This application claims priority from Korean Patent Application No. P2005-0118966 filed on December 7, 2005, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a flat panel display device, and in particular, to a flat panel display device suitable for improving image quality by compensating panel defects with electrical data, and an apparatus and method for controlling the image quality thereof. Background technique [0003] In today's information society, display devices have never been more important as a visual information communication medium. Cathode ray tubes (CRTs) or Braun tubes, which are the mainstream at present, have problems such as large weight and large size. Various types of flat panel display devices have been developed that overcome the limitations of cathode ray tubes. [0004] Flat panel display devices include liquid crystal display LCD, field emission display FED, plasma d...
