Patent Issues
LG Display is explaining its patent competitiveness in China. In the rapidly-growing Chinese market, this is a preemptive move on the possible infringement of patent rights in the future.
The company held a briefing session on LG Display’s major technologies for 150 patent examiners at the Guangdong Patent Examination Center under the State Intellectual Property Office (SIPO) of the People’s Republic of China located in Guangzhou, Guangdong Province on Oct. 27.
During the meeting, Chief Technology Officer Kang In-byeong introduced its company and major technologies, and Convergence Technology Research Team Researcher Lee Deuk-soo explained about the overall touch technologies and its own advanced in-cell touch (AIT) technology.
The AIT is a touch technology that is independently developed by LG Display. It employs a touch sensor embedded within an LCD panel, replacing the “add-on” type that places a touch panel on top of the LCD. Since the technology eliminates the space needed for a touch function cover glass, and as a result reduces the panel’s thickness, it offers a slimmer design and an excellent touch response. In addition, there is no need for an additional process to install a touch panel, reducing production costs, and it features precise calibration of the touch point even with water drops on the screen.
At the session, Kang said, “LG Display applied for 1,900 patents in China, which was over 30 percent of the total patents applied overseas, in the last five years, strengthening patents in China.”
Meanwhile, the cumulative number of patent registrations of LG Display stands at 13,487 in Korea and 13,985 abroad. In the Ocean Tomo, the index based on the value of intellectual property, it received a grade of “Valuable,” which is the highest level. LG Display’s patent competitiveness is being recognized in terms of both quantity and quality.
