Description

Technical Field

[0001] This application relates to the field of testing technology, specifically a backlight testing device for display modules. Background Technology

[0002] The display module is a core component in electronic devices responsible for converting electrical signals into visual images, and it is a key interface for user interaction with the device.

[0003] Backlight testing of display modules is a quality inspection process for the backlight module in LCD display modules. Its core purpose is to ensure that the backlight module can provide a uniform, stable and compliant planar light source, thereby ensuring the display effect of the LCD display panel.

[0004] For example, patent CN221248470U discloses a quality inspection device for LCD backlight modules. This patent uses a movable adjustment unit and an adjustment clamping unit to achieve positioning and clamping of backlight modules of different sizes, and the positioning and clamping is quick.

[0005] In actual use, the display module may be at different tilt angles (such as when the user adjusts the screen angle). However, backlight testing is usually a fixed-angle test, which cannot simulate these scenarios. Therefore, it is impossible to verify whether the backlight performance at different angles meets the design requirements. If the display module is not tilted, it may lead to optical performance distortion, user experience degradation, and product reliability risks.

[0006] Therefore, it is necessary to provide a display module backlight detection device to solve the above problems.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] like Figures 1-3As shown, this application provides a display module backlight testing device. This backlight testing device is mainly installed inside the factory and is used to test the backlight brightness, uniformity, and color of the display module. Specifically, the testing device includes a housing 1, and a bracket 2 is fixedly installed inside the housing 1. In order to smoothly perform backlight testing on the display module, a testing mechanism 3 is provided on the upper end of the bracket 2. The testing mechanism 3 has a camera 38 and a supplementary light 39. The supplementary light 39 is arranged on both sides of the camera 38 for illuminating the display module, so as to provide sufficient light source during the test. The backlight test process is recorded by the camera 38, thereby completing the backlight testing of the display module.

[0040] The detection mechanism 3 also includes a sealing plate 6 fixedly installed on the upper end of the bracket 2, and a displacement component 30 is provided on the upper end of the sealing plate 6. In this application, the displacement component 30 adopts a dual-axis screw transmission mechanism commonly used in the prior art and applicable to this embodiment. The camera 38 and the fill light 39 are installed on the displacement component 30, so that by activating the displacement component 30, the camera 38 and the fill light 39 are moved along the X / Y axis plane, thereby realizing the full-view backlight detection of the display module.

[0041] like Figure 2 and Figures 4-5 As shown, in order to verify whether the performance of the display module at different angles meets the design requirements, a fixing mechanism 4 is provided inside the housing 1 at the lower end of the detection mechanism 3. The fixing mechanism 4 is used to adjust the angle of the display module during the detection process.

[0042] The fixing mechanism 4 includes a base 40 fixedly installed inside the housing 1 at the lower end of the detection mechanism 3, and a large bevel gear 41 rotatably installed on the base 40 at the middle position. A first motor 42 is fixedly installed on one side of the upper end of the base 40. A small bevel gear 50 is fixedly installed at the output end of the first motor 42. The small bevel gear 50 meshes with the large bevel gear 41, so that the first motor 42 can be started to drive the large bevel gear 41 to rotate on the base 40 through the small bevel gear 50.

[0043] Meanwhile, two sets of vertical plates 43 are fixedly installed on the upper end of the large bevel gear 41, and a second motor 44 is fixedly installed on one side of one of the vertical plates 43. The output end of the second motor 44 passes through the vertical plate 43 and is fixedly installed with a gear 45. Meanwhile, a rotating shaft 51 is rotatably installed between the upper ends of the vertical plates 43, and an arc-shaped gear 46 is fixedly installed between the rotating shaft 51. The arc-shaped gear 46 meshes with the gear 45 so that the second motor 44 can be started to drive the arc-shaped gear 46 through the gear 45 to drive the rotating shaft 51 to rotate between the vertical plates 43.

[0044] Furthermore, a fixing seat 47 is fixedly provided at both ends of the rotating shaft 51, and a placement plate 48 is fixedly provided on the upper end of the fixing seat 47. The placement plate 48 has multiple sets of slots 49, which are used to place the display module.

[0045] Therefore, during the testing process, the first motor 42 can be started to drive the large bevel gear 41 to rotate on the base 40 to a suitable position through the small bevel gear 50. Then, the second motor 44 can be started to drive the arc gear 46 through the gear 45 to drive the rotating shaft 51 to rotate between the upright plates 43. While rotating, the fixed seat 47 can be used to drive the placement plate 48 to adjust the angle, thereby enabling the testing of display modules at different angles.
