LG Display was considering applying microlens on its OLED panels aimed at TVs, TheElec has learned.
Microlenses can be used to control the direction of the light reflected from the panel to the direction of the viewer.
This improves the efficiency of light extraction, increasing the brightness of the screen while also decreasing power consumption, sources said.
LG Display is expecting the method to increase the brightness of its OLED panels by up to 20%, they added.
The company is already planning to apply its OLED.EX technology to panels it will start pass producing during the second quarter.
LG Display had claimed this technology increases the brightness of the panels by 30%.
Adding microlens technology to this will mean a brightness increase of 50%, the sources said.
The South Korean company will start applying microlens this year at the earliest, they added.
LG Display, prior to announcing OLED.EX, had said its OLED panels offer up to 800nit in brightness.
OLED.EX, instead of using hydrogen in the blue organic materials used for previous OLED panels, only deuterium is used for the organic material.
This extends the life span of the blue organic materials, allowing LG Display to increase the brightness of the screen.
Meanwhile, microlens technology isn’t something new in the display panel space. Liquid Crystal Display that uses LED backlights uses microlens as the optical sheet, while Samsung’s Galaxy S21 Ultra also used microlens in its OLED panel.
