Display Manufacturing

Excimer Laser Annealing

Coherent pioneered the development of Excimer Laser Annealing for producing Low Temperature Polysilicon TFTs (LTPS and LTPO backplanes) enabling high resolution OLED and MicroLED displays.

Laser Lift-Off

Laser Lift-Off (LLO) gently separates the flexible OLED displays from rigid carriers as well as MicroLED dies from the growth wafer. Scalable UV laser power ensures high throughput and yield.

Flexible OLED Cutting

Ultrashort Pulse and CO₂ lasers perform singulation and trimming of flexible OLEDs, with small kerf width and minimal process affected zone, at high throughput.

MicroLED Processing

Excimer laser based Laser Lift-Off (LLO), Laser Induced Forward Transfer (LIFT), and Individual Pixel Repair are key processes in mass production of MicroLED displays.

Sapphire Wafer Dicing

Ultrashort pulse laser dicing of LEDs fabricated on sapphire substrates for lighting applications reduces production costs and enhances yields.

Success Stories

Amplifier Stability Enables in-situ Studies of Ferroelectric Film Polarization

See how researchers successfully used Coherent Astrella/TOPAS to determine both the degree and direction of polarization, in films from zero to 20 unit cells (u.c.).

Amplifier thermal stability is critical. Our chamber runs at up to 950°C internally and heats the lab significantly during long experiments. The power, beam shape, and pointing of Astrella are all unaffected by these ambient changes.
