An OLED screen life test device

Abstract

The present invention discloses an OLED screen life test device, including a workbench, a signal generator is fixedly connected to one side of the workbench, and a control panel is fixedly connected to the side wall of the workbench. In addition to being able to move in three axes, the multi-axis moving component used to carry the test head assembly of the present invention is also provided with a guide assembly for the curved OLED screen. When detecting the curved OLED screen, an arc guide rail consistent with the curvature of the curved OLED screen is used, and the arc guide rail is rolled in contact with the first guide wheel by pressing down the pressure rod, so that when the adjustment block moves in the X-axis direction, it will be subjected to the pressure of the arc guide rail. Under the action of the spring, the first guide wheel is always close to the arc guide rail, so that the moving trajectory of the adjustment block is a path with a curvature consistent with the arc guide rail and an arc path consistent with the curvature of the curved OLED screen, ensuring that the distance between the test head assembly carried by it and the surface of the curved OLED screen is always consistent, and the movement is smooth. Such temperature test data is more reliable, and the test reliability is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of OLED screen testing, and in particular to an OLED screen life testing device. Background Art

[0002] OLED is also known as organic electric laser display and organic light-emitting semiconductor. OLED screen has the characteristics of low power consumption, thin thickness, pure and delicate colors, and flexibility, so more and more display screens are now using OLED screens. OLED screen is an organic self-luminous display screen. Each pixel is independent and can be lit or turned off individually. Since each pixel is self-luminous, rather than being lit as a whole like LCD, this will cause each pixel of OLED to work for a different time. For example, if some pixels display blue for a long time, then their blue attenuation will be greater than other pixels. When blue is displayed again in the future, the blue of this pixel will be lighter than the others. The same is true for red and green. Therefore, OLED is prone to screen burn-in (residue caused by uneven screen aging). OLED uses organic materials, and its aging speed is much faster than that of inorganic LCD. Therefore, the lifespan of OLED organic materials is not as good as that of LCD. In order to improve the yield rate and extend the service life of OLED screens, it is necessary to continuously improve the production process and select more suitable organic materials. The OLED screen life measurement system provides a reliable basis for these improvements. The current OLED screen life measurement device uses a signal generator to test the current and voltage data of the OLED screen, and uses a temperature probe and a colorimeter to detect the temperature and chromaticity state of the screen surface. The life of the OLED screen is estimated, and a heating system is also used to accelerate the aging of the OLED screen and speed up the test. For example, the Chinese invention patent with the authorization announcement number CN111458109A discloses an OLED screen life measurement system, which includes a gantry frame, an XYZ motion mechanism, a measuring component, a heating cavity, a signal generator, a temperature heating control module and a fixture for fixing the OLED screen, wherein the XYZ motion mechanism is mounted on the gantry frame, the measuring component is connected to the XYZ motion mechanism, the temperature heating control module and the fixture are arranged in the heating cavity, the signal generator is connected to the OLED screen placed in the heating cavity, the signal generator includes an FPGA mainboard, multiple FPGA signal boards and multiple signal transfer boards, the FPGA mainboard is respectively connected to multiple FPGA signal boards, one FPGA signal board is correspondingly connected to one signal transfer board, and one signal transfer board is correspondingly connected to one OLED screen placed in the heating cavity; however, this OLED screen life test device has the following defects:

[0003] The light source of the OLED screen has a planar geometric structure and planar luminescence and heat generation characteristics, and is a non-point light source structure. In the OLED screen studio, the thermal temperature distribution on the light source is very uneven. Therefore, when testing the surface temperature, the temperature probe is required to test the temperature of all locations on the entire surface. For example, the above-mentioned OLED screen life measurement system uses a three-axis XYZ motion mechanism equipped with a temperature measurement structure to detect the surface of the OLED screen. It is necessary to keep the same distance between the temperature measuring head and the OLED screen detection point position to ensure data reliability. However, the OLED screen itself has the characteristic of being bendable and is widely used in curved screens. However, when testing the curved OLED screen, the above-mentioned three-axis XYZ motion mechanism is difficult to maintain a consistent measurement distance. The Z axis needs to be continuously adjusted to maintain the distance. The movement of the temperature measuring head is not smooth, and it is difficult to ensure that the distance between all detection positions and the temperature measuring head is consistent, resulting in unreliable data.
