Resolution increase

XTPL disruptive deposition technology gives the ability to print single micron feature sizes with competitive XY resolution. Such precision opens up vast potential for application in manufacturing of new genera

XTPL technology can be applied in the OLED display manufacturing to precisely deposit active materials, resulting in resolutions for the new generation displays. Modern smartphone displays exhibit high pixel densities approaching 800 PPI. But while display is closer to human eye, the density needs to be higher. For full experience of virtual reality in head mounted devices there is strong need for ultra-high density displays.

OLED displays for VR application currently available in the market have pixel densities of about 1500 PPI. To improve the virtual experience manufacturers are developing displays up to 4000 PPI. Unfortunately, due to the fine metal mask (FMM) approach limitations and lack of additive deposition method for small RGB OLED feature sizes (~2 um of subpixel pitch in 4000 PPI RGB), manufacturers are using WOLED with color filter approach, which decreases potential brightness and lifetime of displays.

Unlike the currently used fine metal mask (FMM) approach, structures obtained with the XTPL printing method do not exhibit shadowing effect. This advance allows for reduced feature size irrespective of the scale. Since XTPL solution is purely additive, no active material is wasted and there is no need for masks to be replaced between the deposition cycles.

XTPL direct deposition approach


Ultra-precise deposition technology developed by XTPL has the ability to print single micron feature sizes with competitive XY resolution. Versatility of the potential materials gives perspective of printing up to 4000 PPI OLED or QDEL (Quantum Dot Electroluminescent) RGB pixel matrices on the currently available TFT backplanes or microLED substrates.

Direct deposition of electroluminescent materials, separate for each of the RGB colors, gives higher brightness (color filters absorbs up to 70% of light), simultaneously decreasing the power consumption and increasing lifetime.

Currently used state-of-the-art ink-jet printers deposit structures with a minimal diameter of 20 um, while the XTPL technology provides microdots as small as 1 um in diameter.
