Samsung Display said on Tuesday it has developed SmartPower HDR, a technology it built with Intel that cuts OLED emission power consumption in laptop HDR mode by up to 22 percent. The technology reduces power use compared with existing HDR mode by adjusting the driving voltage by content. It can improve battery efficiency and the HDR viewing environment as the spread of AI PCs expands.

Existing HDR mode fixed the driving voltage regardless of content. It maintained a high voltage to match maximum brightness. For example, it caused unnecessary power consumption in environments that can operate at low voltage, such as web browsing or document work.

SmartPower HDR varies the voltage depending on content. It cuts OLED emission power consumption by 22 percent versus existing HDR mode in general use environments and by up to 17 percent in high-quality operation environments.

The two companies began development after signing a memorandum of understanding in February last year and have produced results. It analyzes peak brightness values for each frame in real time on the laptop SoC and sends them to the T-CON for OLED panel control. The T-CON analyzes the brightness data and the OPR to adjust the driving voltage to match the content. OPR refers to the ratio of active pixels among all pixels.

Samsung Display IT Strategy Marketing Team Vice President Yongwook Jung said SmartPower HDR is a complete HDR that lets consumers feel and experience HDR’s strengths in real use environments beyond the spec sheet. He said the company will further advance the SmartPower HDR technology and continue developing technologies so more consumers can enjoy clear, high-quality HDR content on laptops through various OLED low-power technologies.

Todd Lewellen, Intel vice president and head of the PC ecosystem and AI solutions, said the display accounts for more than half of a laptop’s total power consumption, making it a key target for efficiency improvements. He said the collaboration goes beyond the limits of visual innovation and represents important progress in boosting performance and optimizing power.
