A device for testing mechanical properties of flexible devices

Abstract

The invention discloses a device for mechanical performance test of a flexible organic light-emitting diode (FOLED), a flexible solar cell (FOPV), a flexible field effect transistor (FTFT) and other flexible devices. The device comprises a fixed bottom plate; a control circuit part is fixedly arranged at one side of the fixed bottom plate, and a mechanism part is arranged at the other side of the fixed bottom plate; the mechanism part comprises a power device, a transmission device, a linear displacement device and two clamping parts; the power device, the transmission device and the linear displacement device are in transmission connection with one another in sequence; the two clamping parts respectively are a static clamping head fixedly connected with the fixed bottom plate and a movable clamping head fixedly connected with the linear displacement device; and the control circuit part is connected with the power device. The device has the advantages that in the process of simulating a hand curved substrate, an electrode can not be damaged, the performance is stable, the test of the organic flexible devices is facilitated, the cost is low, and the manufacture is easy.

Description

technical field [0001] The invention is used for testing the mechanical properties of flexible devices, such as flexible organic light-emitting diodes (FOLED), flexible solar cells (FOPV), flexible field-effect transistors (FTFT), flexible organic electrical storage (FOTM), and other flexible devices. Bend test of substrate. Background technique [0002] OLED is commonly known as Organic Light-Emitting Diode (OrganicLight-EmittingDiode), also known as Organic Electroluminescence Display (OELD). Because of its thinness, power saving, wide viewing angle, and flexibility, it has been widely used and gradually entered the stage of practical application. And its most eye-catching is the flexible display FOLED, which is a significant advantage that all displays on the market do not have. FOLED is an OLED made on flexible substrates such as flexible PET (Polyethyleneterephthalate) or ultra-thin glass, PI (polyimide), etc. Usually, flexible substrates are required to withstand hig...

Problems solved by technology

[0006] Therefore, the research on mechanical properties has always been a hot spot in FOLED experiments, and usually we only use human hands or some simple manual mechanical equipment to test flexible devices, which makes the test results have many human factors, such as: the grease on human hands Stains such as sweat and sweat are easy to contaminate the device, and it is easy to damage the layers and electrodes of the thin film device. It cannot guarantee uniform bending, and cannot guarantee that the bending angle (ie curvature) is the same each time, and the general number of bending times is thousands of times. Tens of thousands of times, so such a test needs to be completed by fully automatic equipment
