Description

Technical Field [0001] The present invention relates to a stylus pen for displaying a contact surface,

The present invention relates to a stylus pen, and more particularly, to a stylus pen and a contact surface display method for a contact surface display in which display is possible in a real contact surface shape in which a stylus pen contacts.

With the development of computers using digital technology, auxiliary devices of computers are being developed together. Personal computers, portable transmission devices, and other personal information processing devices use various input devices such as a keyboard and a mouse And performs text and graphics processing.

However, as the use of computers is gradually increasing due to the rapid progress of the information society, there is a problem that it is difficult to efficiently operate a product by using only a keyboard and a mouse which are currently playing an input device. Therefore, there is an increasing need for a device that is simple and less error-prone, and that allows anyone to easily input information.

In addition, the technology related to the input device is shifting beyond the level that satisfies the general functions, such as high reliability, durability, innovation, design and processing related technology, etc. In order to achieve this purpose, A touch screen has been developed as a possible input device.

Personal computers, portable transmission devices, and other personal-purpose information processing devices perform text and graphics processing using various input devices such as a keyboard, a mouse, and a digitizer.

In particular, a digitizer is a device that digitally detects the position of a stylus or finger placed on a specially manufactured flat plate and outputs it in XY coordinates. It is a device that outputs text or pictures compared to conventional mouse, keyboard, It has the advantage of being able to input conveniently and precisely.

Digitizers are distinguished in three ways, depending on the input tool. The first is to use a pen specially designed as a stylus method, the second is to use a finger as a finger touch method and the last is a touch panel method, Use an object with a protrusion.

The stylus method is widely used for a graphic device, a CAD device, a finger touch method is used for a device using a touch screen, and a touch panel method is used for an electronic notebook or a personal digital assistant (DA) Is used.

In implementing the digitizer system, a tablet for giving coordinate data, a stylus for designating a point in the coordinate system expressed by the tablet, a pointing device such as a finger, and a digitizer controller for controlling them are required.

Tablets have a specially designed rectangular plate. A flat plate called a panel is a sheet of resistance component (stylus and finger touch), or a sheet of two resistance components arranged so that they can be separated by a spacer and contacted with each other by pressing ) (Touch panel method).

At this time, the sensor panel receives coordinates and pressure around the touch area A of the stylus 30.

At this time, a method of calculating the magnitude of the signal and the intensity of the pressure according to the type of the stylus has been proposed. However, in this conventional method, even if the magnitude of the signal changed by the stylus and the intensity of the pressure are known, there is no way to know how the stylus is actually connected to the sensor panel. This also detects only the coordinates and the pressure corresponding to the touched sensor panel regardless of the actual contact shape, and displays it in a predetermined shape (for example, point, circle, line, etc.) regardless of the contact shape. In other words, the virtual thicknesses different from the actual ones were displayed with different points or lines.
