플렉서블 디스플레이의 왜곡 보정 방법 및 이를 이용한 기기 {method for correcting distortion of flexible display and device using the same}Method for correcting distortion of flexible display and device using the same}

플렉서블 디스플레이Flexible display

일반적으로 이동 단말기에서 디스플레이 모듈은 시각적으로 정보를 표시하기위해 사용되는 것으로, 액정디스플레이(liquid crystal display), 박막트랜지스터액정디스플레이(thin film transistor-liquid crystal display), 유기발광다이오드(organic light-emitting diode), 플렉시블디스플레이(flexible display), 3차원디스플레이(3D display) 등으로 구성될 수 있다. 또한 최근에는 플렉시블 디스플레이(flexible display) 기술이 개발되어 디바이스를 접거나 말수 있게 되었지만, 동시에 사용자 시각에서 디스플레이의 정보 왜곡 발생된다.In general, a display module in a mobile terminal is used to visually display information, such as a liquid crystal display, a thin film transistor-liquid crystal display, and an organic light-emitting diode. ), A flexible display, a 3D display, or the like. In addition, in recent years, a flexible display technology has been developed to fold or roll a device, but at the same time, information distortion of the display occurs from the user's perspective.

따라서 이러한 정보 왜곡을 줄이기 위한 방법이 요구된다. 또한 손쉬운 소프트웨어 방식으로 왜곡을 보정할수 있는 방법이 요구된다.Therefore, a method for reducing such information distortion is required. There is also a need for an easy software method for correcting distortion.

플렉서블 디스플레이의 구부림 강도에 따라 사용자에게 왜곡되어 보여지는 문제를 해결하기 위해 화면을 역왜곡을 시키는 방법 및 이를 이용한 기기을 제공한다. The present invention provides a method for reverse-distorting a screen and a device using the same in order to solve a problem in which a user is distorted according to the bending strength of a flexible display.

플렉서블 디스플레이부가 휘어진 위치 및 강도를 판별하는 구부림 판별부; 상기 구부림 판별부의 값에 따라 역왜곡된 정보를 구성하는 정보 구성부; 그리고 상기 정보구성부의 정보를 디스플레이하는 디스플레이부를 포함하는 기기를 제공한다.A bend determination unit that determines a bending position and strength of the flexible display unit; An information constructing unit constituting reversely distorted information according to the value of the bending discriminating unit; And it provides a device including a display unit for displaying information of the information configuration unit.

간단한 알고리즘을 통해 왜곡문제를 실시간으로 해결할수 있다.A simple algorithm can solve the distortion problem in real time.

손목밴딩, 세워두기, 기울여두기 등 다양한 컨텍스트에서 생길수 있는 왜곡문제를 해결함.Resolves distortion issues that can occur in various contexts, such as wrist banding, standing up, and tilting.

더 나아가, 표현되는 정보의 역왜곡 뿐 아니라 입력에서의 왜곡(경사가 높은부분과 낮은부분의 불일치성)도 동일한 역왜곡 알고리즘을 적용할 수 있음.Furthermore, the same inverse distortion algorithm can be applied not only to the inverse distortion of the represented information but also to the distortion (inconsistency between high and low inclinations) in the input.

도 1은 일실시예에 따른 플렉서블 디스플레이의 왜곡 보정 방법을 설명하기 위한 도면이다.1 is a diagram for describing a distortion correcting method of a flexible display, according to an exemplary embodiment.

본 발명은 플렉서블 디스플레이의 구부림 강도에 따라 사용자에게 왜곡되어 보여지는 문제를 해결하기 위해 화면을 역왜곡을 시키는 방법 및 이를 이용한 기기에 대한 것으로, 플렉서블디스플레이부가휘어진위치 및 강도를 판별하는 구부림 판별부; 상기 구부림 판별부의 값에 따라 역왜곡된 정보를 구성하는 정보구성부; 그리고 상기 정보구성부의 정보를 디스플레이하는 디스플레이부를 포함하는 것을 특징으로 한다.The present invention relates to a method for reverse-distorting a screen and a device using the same in order to solve the problem that the user is distorted according to the bending strength of the flexible display, and a device using the same; An information constructing unit constituting reversely distorted information according to the value of the bending discriminating unit; And a display unit for displaying the information of the information structure unit.

본 발명은 플렉서블 디스플레이의 구부림 강도에 따라 사용자에게 왜곡되어 보여지는 문제를 해결하기 위해 화면을 역왜곡을 시키는 방법 및 이를 이용한 기기에 대한 것으로, 일실시 예에서 좌우로 구부리는 경우 구부리는 중심점을 기점으로 좌우를 expand 시킨다(도 1 참조).The present invention relates to a method for reverse-distorting a screen and a device using the same in order to solve a problem of being distorted to a user according to the bending strength of a flexible display. To expand the left and right (see Fig. 1).
