Embodiment Construction

[0028] Embodiments of the inventive concept will be described as follows with reference to the accompanying drawings. These examples are given as teaching examples and should not be construed as limiting the scope of the inventive concept.

[0029] In the following description, where a component is referred to as being “formed on” another component, it may be directly formed on another component, or other intervening components may be present. In contrast, where an element is referred to as being "formed directly on" another element, there are no intervening elements or layers present. Other words used to describe the relationship between elements or layers may be interpreted in a similar fashion (e.g., "between" versus "directly between", "adjacent" for "immediately adjacent", etc.).

[0030] Although the terms first, second, third, etc. are used herein to describe various components, the components are not limited to these terms. Rather, these terms are only used to disti...

Abstract

A method of operating a touch system is provided, the method comprising: storing a look-up table for correcting touch coordinate values ​​of a touch panel; obtaining touch data generated in response to a touch conductor on the touch panel and calculating touch data from the obtained touch data. coordinate values; measure the dimensions of the touch conductor; and correct the touch coordinate values ​​by accessing a lookup table using the touch coordinate values ​​and the dimensions of the touch conductor as input parameters.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0058225 filed on June 18, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the inventive concept generally relate to display systems for electronic devices. More particularly, embodiments of the inventive concept relate to a display system including a touch interface such as a touch panel. Background technique [0004] Certain electronic devices include displays with touch interfaces. Such displays are often referred to as touch screens. A touch interface allows a user to interact with the electronic device through the touch screen by placing an input object, such as a finger or a stylus, in close proximity to the touch screen. Examples of devices with touch screens employed include smartphones, automated teller machines (ATMs), televisions (TVs), and home appliances, to name a ...
