In the fast-paced realm of technology, where innovation is the holy grail, Samsung and LG Display have emerged as the undisputed titans of the OLED panel industry. Renowned for their cutting-edge displays and relentless pursuit of excellence, these two South Korean giants continue to shape the future of visual technology.

To continue maintaining this standard, the two tech giants are reported to have joined forces together to develop higher light efficiency and long-life OLED panels. As reported by TheElec, the upcoming OLED panels will be 20% brighter and have a longer life. Last year, Samsung introduced the Eco2 OLED panel, which has higher energy efficiency and is currently used on the Galaxy Z Flip 4 and Galaxy Z Fold 4.

Samsung and LG OLED Panels

Using a low-refractive CPL (cover layer), Samsung and LG are developing OLED panels. The CPL, which is a remarkably thin coating covering the cathode, prevents light from being lost when it is reflected by neighboring electrodes.

The CPL now in use has a high index of refraction. The light loss can be decreased by adding a layer of low-refractive CPL, enhancing light efficiency, energy efficiency, and product life. However, incorporating a low-refractive CPL could push up the price and complexity of OLED panels even higher.

Previously, LG employed a similar technique known as MLA (microlens array) in its large-size OLED TV panels. This layer, which is composed of countless convex lenses, collects the light produced by the emissive layer and stops it from bouncing. As a result, an OLED panel with MLA can use the same amount of power while being 20% brighter.

According to reports, Samsung Display and LG Display are in discussions with their two largest clients, Apple and Samsung MX (the smartphone division). LG Display and Samsung Display can create OLED panels for phones, tablets, and even laptops if they agree to employ more expensive OLED panels.

Currently, Donjin Semiconductor, Hodogaya, Labto, and PNH Tech are among the businesses creating CPL layers for OLED panels. While PHN Tech is a component of LG Display’s supply chain, Dongjin Semiconductor, Hodogaya, and Labto have approached Samsung Display about doing business. These smaller OLED material producers have already submitted LG Display and Samsung Display samples, and scaled production of OLED panels with low-refractive CPL layers that can start if Apple and Samsung MX agree.

Given the collaboration, it is expected that in the future, Samsung may introduce smartphones, tablets, or laptops with new OLED screens that are brighter, consume less power, and last longer. Thus, stay connected with TechGenyz for more updates.
