Displays

Displays represent a fundamental component in modern electronics, providing visual interfaces for a wide range of devices, from smartphones to large-scale flat-panel displays (FPD). Display technologies depend on materials with diverse electrical conductivity, like ITO. These materials are layered onto substrates, forming the basis for pixelated displays. Utilizing photolithography, intricate patterns are transferred into these materials using masks or direct writing techniques.

Heidelberg Instruments tools are utilized in multiple stages of display production, including the precise and uniform patterning of large photomasks, up to 1400 x 1400 mm² (VPG⁺ 1400), used for insulating and conducting layers prior to integrating liquid crystals or organic compounds (in LCDs and OLEDs). They succeed in generating highly uniform color-filtering arrays. They also find application in the fabrication of backlight illumination panels, in 2.5D micro-structures like diffusers or micro-lens arrays (DWL 2000 GS / DWL 4000 GS), and in the packaging process for integration into electronic devices (MLA 300).
