Abstract

The invention discloses a sensor, a driving method of the sensor, an OLED device and a display device. The sensor comprises a conductive layer, a contact layer and an expansion layer. The contact layer is located between the conductive layer and the expansion layer. The contact layer comprises a first contact structure and a second contact structure. The first contact structure is located on the conductive layer. The second contact structure is located on the expansion layer. The expansion layer is used for increasing the contact area between the first contact structure and the second contactstructure during the expansion process. Or, the expansion layer is used for reducing the contact area between the first contact structure and the second contact structure during the contraction process. According to the invention, the driving current of the OLED device is changed by expanding or contracting the expansion layer. The operation is simple, and the scheme for changing the driving current of the OLED device is simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a sensor and a driving method thereof, an OLED device and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, referred to as: OLED) is an electroluminescent device, which has the characteristics of self-luminescence, high luminous efficiency, low operating voltage, light and thin, flexible and simple process technology, and is used in display lighting and other fields. more extensive. In the existing OLED devices, the change of the driving current of the OLED device is mainly realized by changing the driving voltage of the device. [0003] However, in the prior art, the scheme of changing the driving current is relatively complicated. Contents of the invention [0004] The invention provides a sensor and its driving method, an OLED device and a display device, which are used for simplifying the scheme of changing the dr...
