Embodiment Construction

[0024] The flexible OLED display deformation sensing system of the present invention includes a sensor base layer attached to the back of the flexible OLED display. The outer line layer is a set of control circuits. The sensor array can sense the bending, curling, bending, and deformation of the OLED display screen under local stress. Changes in resistance or capacitance or inductance of the sensor.

[0025] The deformation sensing device is to arrange the strain sensors into a horizontal and vertical matrix respectively, and the horizontal strain sensor 4 and the vertical sensor 5 are fabricated on the sensor base layer 2 by printing, vapor deposition, magnetron sputtering, inkjet printing, spraying, dispensing, etc. On the surface, the sensor array layer is attached to the back of the flexible OLED display and can be deformed with the flexible OLED screen. Its thickness can be 0.001mm-2mm, the bending radius can be 0.1mm-50000mm, and the local force deformation > 0.0002mm (...

Abstract

The invention relates to a flexible OLED (Organic Light Emitting Diode) display deformation sensing system, which comprises a sensor substrate layer attached to the back of a flexible display, whereinthe sensor substrate layer is provided with a sensor array layer, and the sensor array layer is provided with a plurality of leading-out wires. The sensor array layer comprises a strain sensor matrixformed by a transverse array and a longitudinal array, wherein the transverse array is composed of a plurality of transverse strain sensors, the longitudinal array is composed of a plurality of longitudinal strain sensors, each transverse strain sensor is provided with a transverse leading-out wire, and each longitudinal strain sensor is provided with a longitudinal leading-out wire. The transverse array sensor capture longitudinal strain point coordinates and strain values, and the longitudinal array sensors capture transverse strain point coordinates and strain values. The sensor layer cancapture a deformation mode and a deformation device of the display screen in real time. The flexible deformation action of the OLED display is captured into a digital signal so as to be used for controlling the display, a data interaction action and other control actions.
