EasyInspect for ITO/TCO hard-coated film inspection ensures optimum OLED and TFT quality of the base material and of the coatings of the finished product.
EasyMeasure monitors physical material properties, such as area distribution of local coating thickness, doping, uniformity of optical density or local surface resistivity/capacity.
EasyInspect for ITO/TCO hard-coated film inspection is used for local defect detection, for example scratch detection, hole detection and particle detection of particles as small as 1 µm.
The brightness of an OLED-based illumination or display is determined by the following factors:
By measuring electrical resistivity, coating variations become visible as variations in brightness and color, and can be displayed and monitored by EasyMeasure.
The surface sensitivity of touchscreens depends largely on the local surface resistivity or capacity which is mainly influenced by the TCO coating thickness and/or doping. Deviations in this can cause different levels of light transmissibility which are monitored by EasyMeasure.
