Key Patent Report - Single Layer Touch Sensor - 2013
Intellectual Properties 2013
As smartphones have become common, the touch user interface (UI) has emerged as a global standard. It is even threatening the position of keyboard and mouse, which have dominated the market as the only UI for the past 50 years. Tablet PC has further accelerated the spread of touch UI, and global leading companies are putting spurs to the technological development for touch panels larger than 10 inches, increasing competition in this sector. The capacitive touch technology has settled as the basic touch UI in small- and mid-sized mobile devices. Recently, the single layer touch technology, which uses a single ITO layer, is adopted more and more. The single ITO layer is lighter and thinner than such touch methods as the GFF, which uses double ITO layers, and can reduce costs and simplify the process. In addition, there are attempts to apply the single layer touch to mid- and large-sized touch panels, including tablet PC and laptops along with the recent release of Windows 8.
Scope of Technologies for Patent Analysis
Report Overview
• Patent Search and Related Patent Selection - Research Period: 1 January 1993 – 19 November 2012 - Research Scope: Published or issued U.S. patents - Patent Search DB: FOCUST, USPTO • Patent Analysis Method - Quantitative Analysis (Trend): A total of 1,904 patents related to capacitive touch technology were selected from the raw-data of 2,335 patents to analyze the trend of patent application (by year, by applicant, and by applicant’s nationality). - Qualitative Analysis (In-Depth): First, 105 patents related to the single layer touch technology were selected from the 1,904 patents related to the capacitive touch technology, and then 96 legally valid patents were chosen as key patents. This report includes an in-depth analysis on these key patents from various angles by major company. It analyzes the status of key patents; the technology development map; major indicators of key patents; key patent abstract; and embodiments of key patents. (* The details of nine invalid patents were also included as reference.) Frequency • Special Format • PDF Length • 138 pages
Displaybank, recently acquired by IHS, recently published a report on a key patent analysis of single layer touch sensor technology. This report covers patents on G1 touch sensor based on single ITO layer; and those related to the G2, GG2 (SITO), on-cell/in-cell touch sensors based on 1.5 ITO layers using the bridge electrode. The report is expected to be of a great help to see the development trends of the single layer touch sensor technology and the key patent technologies as it provides patent application trends of the single layer touch sensor technology and the analysis of key patents of major companies. Patent Application Trends Looking at the 1,904 patents related to capacitive touch technology, the number of application has shown a stiff increasing trend since 2007 (600 patents) after Philips and IBM first applied for related patents in 1993. Meanwhile, the patents related to the single layer touch started to be applied in 2002 with the application of 3M (1 patent) followed by 35 patents applied (7.3%) in 2010, 28 patents (7.4%) in 2011, and seven applied (8.0%) in 2012. It is found that the proportion of the patents on single layer touch technology has been steadily increasing in the total patents on the capacitive touch technology. Key Patent Analysis Of the total of 105 patents, related to single layer touch, 96 legally valid patents published or issued in the U.S. were extracted as key patents for an in-depth analysis by major company. Key patent analysis includes the status of key patents; technology development map; key patent abstract; and analysis of key patent embodiments. -Samsung Electro-Mechanics (13 patents), Samsung Display (8 patents), Apple (6 patents), Cypress Semiconductor (6 patents), LG Display (5 patents), TPK Touch Solutions (5 patents), Others (53 patents, total 35 assignees)
