Abstract
Disclosed are a flat panel display and a method for fabricating the same to connect defective sub-pixels to normal sub-pixels adjacent thereto, drive defective sub-pixels using thin film transistors of the normal sub-pixels and thereby repair the defective sub-pixels.
Claims20
A flat panel display comprising:
- a display panel including a plurality of sub-pixels defined by intersections of a plurality of gate lines and a plurality of data lines, each sub-pixel including a thin film transistor and a pixel electrode connected to the thin film transistor;
- and
- a link pattern connecting a pixel electrode of a defective sub-pixel from the plurality of sub-pixels to a pixel electrode of a sub-pixel that is not defective and is adjacent to the defective sub-pixel.
A method for fabricating a flat panel display comprising:
- forming a display panel comprising a plurality of sub-pixels defined by a plurality of gate lines and a plurality of data lines, wherein each sub-pixel comprises a thin film transistor, a pixel electrode connected to the thin film transistor, and a common electrode overlapping the pixel electrode via an insulating film to form fringe field switching;
- identifying a defective sub-pixel from among the plurality of sub-pixels;
- and
- connecting a pixel electrode of the defective sub-pixel to a pixel electrode of a sub-pixel that is not defective and is adjacent to the defective sub-pixel through a link pattern.
A method of operating a flat panel display including a plurality of sub-pixels defined by intersections of a plurality of gate lines and a plurality of data lines, each sub-pixel including a thin film transistor and a pixel electrode connected to the thin film transistor, and a link pattern connecting a pixel electrode of a defective sub-pixel from the plurality of sub-pixels to a pixel electrode of a sub-pixel adjacent to the defective sub-pixel, the method comprising:
- transmitting a data voltage to the defective sub-pixel via the sub-pixel adjacent to the defective sub-pixel;
- and
- in response to the data voltage, driving both the sub-pixel and the defective sub-pixel adjacent to the sub-pixel.
