Technology trends for improving contrast ratio in IPS mode
The IPS mode is going to lead the large TFT LCD technology for application among other liquid crystal (LC) mode. TFT-LCD TV has begun to rapidly occupy a large portion of the TV display market due to features including thinness, light weight, compactness. Aside from specification of features, the most emphasized aspect has been the contrast ratio for better image quality. To increase contrast ratio, Back Light (B/L) optical configuration, color filter material, sub-pixel structure, rubbing condition optimization, and all that cell characteristics have been investigated. As the results from experimental, applications of a newly developed color resin, new light collimation optical sheet, and surface morphology of finger electrode were the most effective for achieving high contrast ratio.
