Problems solved by technology
[0003] The usual practice in the prior art is to take the bending stress into consideration in the early stage of flexible panel design, but when making flexible panels, there is no real-time monitoring of whether the panel bending stress exceeds the design value or changes over time. The detection device of the situation, which leads to the problem that the reliability of the whole machine cannot be guaranteed

The invention relates to a detection device and method, and the device comprises a detection element which is disposed in a bending region, is connected with a flexible panel, and is bent along with the bending of the flexible panel; a control device which is connected with the detection element and comprises a resistance value and stress curve unit corresponding to the detection element, a resistance value calculation unit and a current transmission unit, wherein the current transmission unit is used for transmitting current to the detection element, and the resistance value calculation unitis used for calculating the resistance value of the detection element; the resistance value and stress curve unit is used for displaying the bending stress of the detection element according to the resistance value calculated by the resistance value calculation unit; and a voltage measurer which is connected with the detection element, wherein the voltage measurer is used for measuring the voltagevalue of the detection element. According to the invention, the bending stress change condition of the metal wire in the flexible panel during bending can be monitored in real time.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device and a detection method for detecting the bending stress of a bending area on a flexible panel. Background technique [0002] In the application of flexible panels, when the flexible panel is bent, if the bending stress is too large, it will often lead to de-lamination of the metal traces on the flexible panel or even the failure of the whole machine. Therefore, how to know the metal traces at an early stage? The rule of changing the bending stress that the wires bear when bending with the flexible panel is an important issue for panel manufacturers and brand manufacturers. [0003] The usual practice in the prior art is to take the bending stress into consideration in the early stage of flexible panel design, but when making flexible panels, there is no real-time monitoring of whether the panel bending stress exceeds the design value or changes over time. The detection de...
