Apple gain another patent

Apple on Tuesday gained a touch-screen LCD technology patents, the use of the patented technology can touch components integrated into the display circuit, to produce thinner and lighter panels. Apple iPhone smartphone may just be using this patented technology, enabling the mobile phone has become lighter and thinner.

Apple called the "touch LCD Patent U.S. Patent No. 8,243,027 patent describes the tactile component of the touch screen integrated into the LCD in a variety of methods. With existing technology, existing technology is the touch layer on top of the screen panel. The patent document also this new patents and many multi-point touch and LCD technology patent control.

Currently used in the iPhone 4S on the LCD touch screen technology on cell technology, namely glass and glass structure, that is touch capacitor element is sandwiched between the top of the display unit glass and tempered glass protection. In the bottom of the LCD top-level glass for liquid crystal array, the bottom of the glass and backlight device.

In-cell technology is to go in addition to top-level substrate, the glass layer, the LCD and touch components integrated into a single structure. Integration of these components, as described in this patent document, there are a number of ways. Apple said in the patent document, integrated LCD hierarchy with the touch sensor, can bring many advantages, not only can reduce the structural level, in order to reduce the cost and the thickness of the touch-screen LCD, but also can simplify the production process.

Apple described in this patent document, including an integrated approach is particularly interested in this method can be applied to conventional and board switching (IPS) panel, the iPhone 4S retinal displays and many other Apple products are used within the board switching technique. Apple patents related to the in-cell IPS panel concept, the technology support for display update of the same electrode was used for touch perception in order to achieve the touch function.

In April of this year, there are market rumors that Apple will in-cell touch screen technology, reduce the weight of the phone when the phone screen from 3.5 inches to 4 inches and the thickness of the new generation of iPhone. In July of this year, "Wall Street Journal confirmed market rumors. Display manufacturers such as Sharp and LG have the class in-cell technology, it is believed a new generation of iPhone display will adopt this technology.

Tuesday's patent document describes the display of similar rumors in-cell technology, including integration of the tactile component to the method of the LCD array, but also an overview of the manufacturing process of the production of this new type of display
