Abstract
A flexible display device and a method for accurately recognizing a user's flex input bending of the flexible display device is described. The present invention is able to discard unintentional flexing of the flexible display device while being able to accurately recognize a user's intended flex input command based on a number of bending degree thresholds. A first bending threshold must be overcome in order to initially recognize a user's flex input as a valid flex input command. Then the user's flex input must fall below a second bending threshold in order to cease the recognition of the user's flex input as a valid flex input.
Claims26
A method for detecting a bend on a flexible display device having a display unit for displaying images, the method comprising:
- detecting, by the flexible display device, a first bend of a first direction on the flexible display device and measuring a first degree of the first bend;
- recognizing the first bend as a first valid flex input when the measured first degree surpasses a first error threshold value;
- and
- recognizing an end of the first valid flex input when the measured first degree falls below a first release threshold value,
- wherein a maximum degree of bend measured during the first bend is recognized as a first peak value,
- wherein the first error threshold value is determined based on a degree before the flexible display device is bent, and the first release threshold value is determined based on the first peak value, and
- wherein the first release threshold value is greater than the first error threshold value.
