Abstract
A method of fabricating LCD devices from large array substrates having redundant pixels. Large array substrates without defects can be used to fabricate large LCD device and the redundant pixels can be disabled. Large array substrates with defects can be cut into smaller array substrates and then used to form small LCD devices. The pixels around the cutting lines of the large array substrate are redundant and can be covered or disabled.
Claims21
A method of manufacturing a liquid crystal display device, comprising;
- forming an array substrate having (M+m) gate lines and (N+n) data lines to define a matrix of (M+m)×(N+n) pixels, wherein the (M+m)×(N+n) pixels include (M×N) display pixels and (Mn+Nm+mn) redundant pixels;
- testing the display pixels for electrical defects;
- and
- disabling the redundant pixels if the display pixels are defect free.
A method of manufacturing a liquid crystal display device, comprising;
- forming a plurality of pixels in a matrix on a first substrate;
- testing the formed pixels for defects;
- cutting the first substrate into a plurality of small substrates when a defect is found;
- providing a plurality of second substrates that correspond in size to the cut small substrates, wherein the cut small substrates are comprised of defect free pixels;
- assembling a second substrates to each small substrate, respectively;
- injecting liquid crystal into a space between the small substrates and the second substrates;
- and
- sealing the space using a sealant.
