Display and Touch Panel Inspection

Dr. Schenk offers precise and reliable optical inspection and glass measurement solutions for all kinds of display and touch panel manufacturing technologies. Touch panels and display cover glass must meet the requirements of crystal clear images, withstand every day application and allow smooth touch screen use.

GlassInspect inspects 100% of the glass surface for local defects and GlassMeasure monitors large area material variations, e.g. homogeneity of coating layer thickness during all steps of touch panel and display glass production.

    • Cover glass inspection (e.g. bare / decorated / printed / coated glass)
    • Touch sensor inspection (e.g. one-glass-solutions OGS)
    • Cell inspection
    • Liquid crystal module inspection

    The glass can be inspected at each and every step during the manufacturing process offering comprehensive quality and process control.

    Dr. Schenk's solutions offer in-line inspection of all glass types involved in the making and processing of various kinds and sizes of displays. For example, they are used in mobile display inspection (smart phones, tablet-PCs and e-readers), touch-sensitive display glass inspection for all kinds of touch panels, e.g. OGS, TOL, etc.

    GlassInspect & GlassMeasure for cover glass and touch panel inspection use Dr. Schenk’s unique MIDA Technology so one defect generates multiple images to deliver the most comprehensive material analysis on the market.
