The technology industry continues to be a hotbed of patent innovation. Activity is driven by the increasing demand for vibrant and energy-efficient display technologies, as well as the expanding application of OLED screens in various consumer electronics and professional displays, and growing importance of technologies such as algorithms and control circuits to dynamically adjust pixel luminance levels, ensuring consistent and high-quality visual output. In the last three years alone, there have been over 4.1 million patents filed and granted in the technology industry, according to GlobalData’s report on Innovation in technology: OLED pixel compensation circuits.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

190+ innovations will shape the technology industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the technology industry using innovation intensity models built on over 1.5 million patents, there are 190+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, network-on-a-chip, in-memory computing, and aural exciters are disruptive technologies that are in the early stages of application and should be tracked closely. Electron beam lithography, OLED pixel compensation circuits, and PCI power management are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are capacitive touch panels and emergency communications network, which are now well established in the industry.

Innovation S-curve for the technology industry

OLED pixel compensation circuits is a key innovation area in technology

OLED pixel compensation circuits are integral components found in image display devices and pixel circuits. Their purpose is to rectify irregularities in pixel brightness that arise from disparities in OLED materials and production processes. These circuits commonly employ amplifiers, data drivers, and capacitors to regulate the voltage supplied to the pixels, thus mitigating non-uniformity.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 100+ companies, spanning technology vendors, established technology companies, and up-and-coming start-ups engaged in the development and application of OLED pixel compensation circuits.
