Referring to fig. 1 and 2, fig. 1 is a schematic diagram illustrating a first structure of a flexible panel testing apparatus 100 according to the present invention, and fig. 2 is a top view illustrating the first structure of the flexible panel testing apparatus 100 according to the present invention. Therein, the flexible screen testing apparatus 100 includes a transmission member 10. The two ends of the transmission component 10 are provided with mounting tables 101, the transmission component 10 is provided with an annular groove 102, the annular groove 102 is located between the mounting tables 101 and the mounting tables 101, the flexible screen 20 is rolled on the mounting tables 101, and the transmission component 10 rotates to unfold the flexible screen 20. The flexible screen 20 includes a testing portion 201 and a display portion 202, the testing portion 201 is located around the display portion 202, the testing portion 201 is installed on the mounting table 101, the display portion 202 is arranged corresponding to the annular groove 102, and a gap is formed between the display portion 202 and the transmission member 10.
The display portion 202 may refer to an Active Area (AA) of the flexible screen 20, i.e., an operable Area of the display screen on which text and graphics are displayed.
In one embodiment, the display portion 202 is disposed on one side of the testing portion 201, and partially covers the testing portion 201, so that the testing portion 201 is disposed around the display portion 202. Specifically, the test section 201 may employ any one of Polyethylene (PE), polyimide (PI), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), or polyethylene naphthalate (PEN). The polymer material has good flexibility, light weight and impact resistance, and can well disperse stress. In this setting manner, it is not necessary to set an individual test area for the flexible screen to be tested, and only the flexible screen to be tested is required to be attached to the test portion 201 as the display portion 202. The method of arranging the display part 202 on one surface of the test part 201 has the advantages of convenient manufacturing process and high production efficiency.
In one embodiment, a mounting area is disposed within the test portion 201, and the display portion 202 is embedded in the mounting area and connected to the test portion 201. Specifically, the test portion 201 may refer to a non-effective display area or a Dummy area (Dummy area) of the flexible screen 20.
The Dummy area (Dummy area) is generally used to protect the display area in a test process of the display panel. For example, in the photolithography process, the influence on the accuracy of the physical pattern of a key component and further the influence on the size of the key component due to the reflection and diffraction of light in the photolithography process is avoided. Or, prevent the chip from causing etching failure due to over or under exposure during the manufacturing process. The Dummy area can also prevent the influence of interference signals in the chip on the key signals. Therefore, the Dummy area is an area usually set in the display panel, and in the embodiment of the present invention, the Dummy area may be set on the mounting table 101 as the test portion 201, so that during the test of the flexible screen 20 being rolled and unrolled, the mounting table 101 can be prevented from pressing the display portion 202, which may cause uneven display.

The transmission component 10 includes a mounting table 101 and a connecting shaft 103, the connecting shaft 103 has a first end 103a and a second end 103b opposite to each other, and the mounting table 101 is disposed at the first end 103a and the second end 103b. Since the mounting tables 101 are disposed at the first and second ends 103a and 103b of the connecting shaft 103, an annular groove 102 is naturally formed between the mounting tables 101 and 101.
By forming the transmission member 10 in the embodiment shown in fig. 3, the mount 101 and the connecting shaft 103 are detachable and not of an integral structure. Therefore, the distance between the mounting tables 101 and 101 can be conveniently adjusted, and the transmission component 10 is suitable for flexibility tests of flexible screens 20 with different sizes. In addition, mounting platforms with different sizes and shapes can be replaced at two ends of the connecting shaft 103, so that different flexible test requirements can be met, and the flexible screen test equipment 100 is wider in application.
