Description

Technical Field

[0001] This utility model relates to the field of testing flexible components, specifically a device for testing the bending resistance of a bendable polarizer for flexible display devices. Background Technology

[0002] The full name of a polarizer is polarizing film. The imaging of liquid crystal displays relies on polarized light. All liquid crystals have two polarizers, one in front and one behind, closely attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. If either polarizer is missing, the liquid crystal sheet cannot display an image. 3D glasses use this principle. During the production of polarizers, a bending resistance testing device is needed to test the bending resistance of the polarizers.

[0003] For example, a display screen performance testing device (authorization announcement number CN218584322U) includes a flipping structure and a clamping component; the two ends of the flexible display screen to be tested are placed on a rotating plate and a fixed plate, then two clamping plates are placed on each end of the flexible display screen, and then connecting screws are inserted into the insertion holes at both ends of the four clamping plates. The connecting screws are then rotated so that they enter the corresponding connecting threaded holes. As the connecting screws continue to enter the connecting threaded holes, the flexible display screen is pressed and fixed on the fixed plate and the rotating plate. Then, a motor drives the rotating plate to rotate towards the fixed plate.

[0004] The aforementioned device can clamp and fix flexible displays of different sizes by setting up a clamping plate. The fixing process is very convenient and replaces tape without wasting resources. However, the aforementioned device does not have a device to simulate the test environment, which results in poor test results because the device cannot simulate extreme use environments or performance degradation under light aging.

The dustproof net 47 is fixedly connected to the rear end of the fixed bracket 41, placed at the two end slots, and placed at the rear end of the first fan 45 and the second fan 46.

[0033] In this embodiment:

[0034] When simulating the testing environment is required, the UV camera 33, temperature and humidity sensor 34, and UV lamp 36 can be activated via the display controller 12. After the UV lamp 36 is activated, it emits ultraviolet light to irradiate the polarizer. Simultaneously, after the UV camera 33 is activated, it can photograph and record the bending of the polarizer to study performance degradation under photomechanical coupling. After the temperature and humidity sensor 34 is activated, it can detect the temperature and humidity inside the isolation housing 31. The temperature and humidity sensor 34 and UV camera 33 can send the detected data to the display controller 12 via a data cable for processing and display. When the display controller 12 receives the temperature data and finds that the temperature inside the isolation housing 31 is low, it can activate the heating element 44 and the first fan 45. After the heating element 44 is activated, it heats the surrounding air. After the first fan 45 is activated, it draws in external air, forces it through the dustproof net 47 to block dust, and then blows it out. Inside the isolation housing 31, air blown into the isolation housing 31 drives the hot air around the electric heating tube 44 into the isolation housing 31 to heat and simulate a high-temperature operating environment. When the display controller 12 detects that the temperature inside the isolation housing 31 is high, it can control the first fan 45, the second fan 46 and the semiconductor heat sink 43 to start. After the semiconductor heat sink 43 is started, the cold end on the left can cool the air on the left side and the hot end on the right can dissipate heat. After the first fan 45 is started, the heat inside the isolation housing 31 and the heat dissipated from the hot end on the right side of the semiconductor heat sink 43 can be drawn in through the heat conduction channel 42 and blown to the external environment. After the second fan 46 is started, the external air can be drawn in, and the air can pass through the dustproof net 47 to block the dust before being blown into the isolation housing 31. The air blown into the isolation housing 31 drives the cold air on the left side of the semiconductor heat sink 43 into the isolation housing 31 to cool down and simulate a low-temperature operating environment.

[0035] This invention provides an improved test device for the bending resistance of a bendable polarizer for flexible display devices. By incorporating an environment simulation component 4 that can simulate the testing environment, the device can simulate performance degradation under extreme usage conditions or light aging, resulting in better testing results.
