Mobile communication terminal case and tablet pc case

Abstract

The present invention relates to a mobile communication terminal case capable of accurately measuring the position of an electronic pen tip. The mobile communication terminal case comprises: a main body unit arranged at an outer surface of the mobile communication terminal such that a touch screen of an electronic device may be exposed outwardly; a position measuring unit including an electronic pen for inputting a content to be displayed on the touch screen, and position measuring means arranged at one side of the main body unit to measure the position of the electronic pen tip; and a communication unit which transmits information on the position of the electronic pen tip measured by the position measuring unit to the mobile communication terminal. Thus, the position of a character or symbol to be inputted can be accurately measured in inputting the character or symbol in an electronic device with a touch screen, thereby improving the reliability and preventing the erroneous operation of the device. Thus, time taken to input a character or symbol is shortened to achieve improved convenience of use.

Description

technical field [0001] The invention relates to a mobile communication terminal cover and a tablet computer cover, in particular to a mobile communication terminal cover and a tablet computer cover capable of accurately measuring the position of an electronic pen tip. Background technique [0002] A touch pad is attached to a display portion of a general touch screen to perform corresponding functions. This kind of touch screen is generally configured in a personal data assistant (Persnal Digital Assistant, PDA) is relatively stable and typical, but with the development of a graphical user interface (Graphic User Interface) in various instruments, it is also widely used in navigators (Navigation), Electronic payment machines (Point-Of-Sale, POS), automatic teller machines (Automatic Teller Machine, ATM), portable multimedia players (Portable Multimedia Player, PMP) and mobile communication terminals and other electronic instruments. [0003] In the above-mentioned touch scr...

Problems solved by technology

[0005] However, in this existing text or symbol input method, due to the relatively limited size of the touch screen, the text or symbols displayed on the character board or symbol board are arranged at relatively dense intervals, so that it often happens that the electronic pen or symbol cannot be correctly perceived. The phenomenon that the user's finger touches the position on the touch screen with pressure changes or the phenomenon that static electricity cannot be sensed

[0006] Not only the reliability of the product is lowered because the characters or symbols required by the user cannot be input correctly, but also it takes a long time to input the required characters or symbols due to malfunction, resulting in inconvenience in use.
