  • Method for detecting a flexion exerted on a flexible screen and device equipped with such a screen for implementing the method
    Patent number: 8564573
    Abstract: Present day, technology allows flexible screens to be produced, particularly the OLED screen technology. The invention relates to a device equipped with a flexible screen emitting light. Part of the light rays emitted by the optical cells is imprisoned between the substrate layers and reflecting from one layer to the other exit at the side of the screen. Photoelectric detectors are arranged on the side of the screen in order to capture the incident light. Depending on the position of the cells emitting the light and the values supplied by the detectors, the central processing unit determines the areas of flexion applied to the screen. Hence, it is possible to introduce commands by exerting flexions on certain areas of the screen. The invention also relates to a device having a flexible screen and flexion sensors capable of executing the method for the introduction of commands.
