Description

Technical Field

[0001] The utility model relates to the technical field of display module production, in particular to a light leakage detection system for a camera hole of a display module. Background Art

[0002] In a mobile phone display module, a blind hole structure design is usually adopted to hide the installation of a camera therein. Please refer to Figure 1 As shown, that is, a camera hole 110 is formed in the display module 100. Since the light of the camera hole has a great influence on the imaging effect of the camera, two glue processes are designed at the edge of the camera hole to prevent the backlight light from entering the hole area.

[0003] However, the camera hole is usually small. At the same time, due to the dispensing process and the characteristics of the glue, the required dispensing area cannot be fully coated, so a certain degree of light leakage will occur. Therefore, after the production line is completed, it is usually necessary to manually check by QC to confirm whether the light leakage of the camera hole is okay. However, in the manual detection process, the detection angle and the degree of light leakage cannot be quantified, and it is easy to cause visual fatigue, resulting in low detection efficiency and the problem of light leakage. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a light leakage detection system for a camera hole of a display module, so as to improve the detection efficiency and avoid the problem of missed detection at the same time.

[0021] Figure 3 is Figure 2 Schematic structural diagram of a lighting fixture for a light leakage detection system of a camera hole of a display module in; Detailed implementation manners

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] Please refer to Figure 2 As shown, a light leakage detection system for a camera hole of a display module includes: a display module 100, a lighting fixture 200, a support frame 300, and a brightness detection module 400. A camera hole 110 is provided on the display module 100. The display module 100 is placed on the lighting fixture 200. The lighting fixture 200 is used to position the display module 100, and the display module 100 is also electrically connected to the lighting fixture 200. The lighting fixture 200 is further used to light up the display module 100. The support frame 300 is arranged on one side of the lighting fixture 200. The brightness detection module 400 is arranged on the support frame 300. The brightness detection module 400 includes an isolation lens barrel 410 and a brightness sensing member 420. One end of the isolation lens barrel 410 covers the camera hole 110, and the brightness sensing member 420 is arranged at the other end of the isolation lens barrel 410. The brightness sensing member 420 is used to perform light collection sensing on the light in the isolation lens barrel 410. And the lighting fixture 200 is electrically connected to the brightness sensing member 420, so that the brightness sensing member 420 feeds back the detection result to the lighting fixture 200.

[0024] It should be noted that the display module 100 is placed on the lighting fixture 200. The lighting fixture 200 is used to position the display module 100, and at the same time, the display module 100 is electrically connected to the lighting fixture 200. For example, a connector matching the flexible circuit board connector on the display module 100 is provided on the lighting fixture 200, so that the display module 100 and the lighting fixture 200 form an electrical connection; further, the isolation barrel 410 is sleeved on the camera hole 110, that is, the camera hole 110 is surrounded by the isolation barrel 410 to separate the camera hole 110 from the outside world and prevent external light from affecting the light collection induction of the light intensity sensor 420; then the light leakage condition of the camera hole 110 can be detected by the light intensity sensor 420, and then the detection result is fed back to the lighting fixture 200 by the light intensity sensor 420. After receiving the feedback signal, the lighting fixture 200 displays the words "PASS" or "NG" on the display screen of the display module 100. In this way, the QC inspector at this position can directly determine whether the camera hole 110 passes the light leakage test through the result on the display screen. Thus, the light leakage detection can be quantified, visualized, and speeded up, improving the detection effect and accuracy to avoid missed inspections. That is, the lighting fixture 200 and the light intensity sensor 420 can be connected through the detection result feedback circuit. Further, the light intensity sensor 420 can be a light intensity sensor.

[0025] Please refer to Figure 3 As shown further, a positioning plane is provided on the lighting fixture 200, and at least two positioning blocks 210 are provided on the positioning plane. The two positioning blocks 210 are respectively used to limit the display module 100. In this way, the position deviation of the display module 100 can be avoided. For example, the positioning block 210 has an "L" - shaped structure, and each positioning block 210 abuts against two of the corners of the display module 100.

[0026] Further, the positioning block 210 is a rubber buffer block to avoid bump damage between the display module 100 and the positioning block 210.

[0027] Preferably, the isolation barrel 410 has a circular structure. That is, the inner diameter structure of the isolation barrel 410 has a circular structure to match the outer shape structure of the camera hole 110. Further, the aperture of the isolation barrel 410 is larger than the aperture of the camera hole 110 to ensure that the isolation barrel 410 can completely cover the camera hole 110.

[0028] In one embodiment, a light-shielding buffer member is provided at one end of the isolation lens barrel 410 facing the display module 100. When the isolation lens barrel 410 covers the camera hole 110, the light-shielding buffer member surrounds the periphery of the camera hole 110. In this way, by providing the light-shielding buffer member, it is not only possible to prevent the isolation lens barrel 410 from damaging the surface of the display module 100, but also to further play a role in light-shielding and sealing, preventing light from leaking out through the gap between the isolation lens barrel 410 and the display module 100. For example, the light-shielding buffer member is a black foam pad.

[0029] Furthermore, in order to improve the intelligence of the display module camera hole light leakage detection system, the display module camera hole light leakage detection system further includes a lifting module. The lifting module is connected to the support frame 300 and is used to drive the support frame 300 to move up and down, so that the isolation lens barrel 410 moves up and down in a direction closer to or farther from the lighting fixture 200. That is, when the display module 100 is placed on the lighting fixture 200, the lifting module drives the support frame 300 to move up and down, so that the isolation lens barrel 410 can move closer to the camera hole 110. When the detection operation is completed, the lifting module is used again to move the isolation lens barrel 410 away from the camera hole 110. In this way, it is convenient to remove the display module 100. For example, the lifting module is a linear motor module.

[0030] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
