[0030] Next, embodiments of the present application will be described in detail with reference to the drawings.
[0031] As Figure 1 shown, the anti-glare camera module 100 includes a lens 20, a blue glass filter 30, a base 40, and an image sensing and processing component 50. Among them, the base 40 is disposed between the lens 20 and the image sensing and processing component 50.
[0032] As Figure 2 shown, the base 40 includes a bonding part 41 located on the outer periphery of the base 40 and a main body part 42 located inside the base 40. Among them, the upper surface of the bonding part 41 is provided with an adhesive layer for bonding the lens 20. The adhesive layer can specifically be a glue layer. The main body part 42 protrudes above the bonding part 41 to form a step structure 43, and the step height of the step structure 43 is greater than or equal to a height threshold. The height threshold is equal to the maximum thickness of the adhesive layer before the lens and the base are pressed together.
[0033] As Figure 2 - Figure 3As shown, the blue glass filter 30 is embedded in the upper surface of the main body 42; the upper surface of the blue glass filter 30 includes a light-transmitting area 31 and a peripheral area 32; the peripheral area 32 surrounds the light-transmitting area 31 externally and is provided with an ink layer 33. In a specific example, the ink layer 33 is a screen printing ink layer.
[0034] It should be noted that the relationship between structures should be understood in a broad sense. For example, the orientation or positional relationship indicated by "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
[0035] It can be understood that the image sensing and processing component 50 is used to collect and process images based on the image light converged by the lens 20. In a specific example, it may include an image sensor, an image processing chip, and a circuit board.
[0036] According to the anti-glare camera module of the embodiment of the present application, by making the main body corresponding to the photosensitive area protrude above the bonding part for bonding the lens to form a step structure, and the step height of the step structure is greater than or equal to the thickness of the glue layer before the lens is pressed onto the base; and by embedding the blue glass filter in the upper surface of the main body, and an ink layer is arranged on the peripheral area of the upper surface thereof. Thereby, it can effectively prevent the adhesive from overflowing onto the blue glass filter, help avoid glare in the camera module, improve the imaging quality, and thus be beneficial to improving the yield rate of the camera module.
[0037] In the embodiment of the present application, the upper surface of the blue glass filter 30 is flush or nearly flush with the upper surface of the main body 42 of the base 40.
[0038] Preferably, the step height of the step structure 43 is less than twice the thickness of the glue layer to balance the reliability of anti-glare and the spatial layout. In a specific example, the thickness of the glue layer is 0.6 mm, and the step height of the step structure 43 is 1 mm.
[0039] In the embodiment of the present application, the light-transmitting area 31 of the blue glass filter 30 includes a main area 34 and four extended areas 35. Among them, the main area 34 is rectangular, and the four extended areas 35 correspond to the four vertices of the main area 34 one by one; the extended area 35 is an area extended from the corresponding vertex to the outside of the main area 34. Thereby, it can effectively improve the illuminance of the edge area, further improve the overall quality and visual effect of the image, and help improve the user experience.
[0040] Preferably, the first boundary line between the outward expansion area 35 and the outer peripheral area 32 is perpendicular or parallel to the second boundary line between the light-transmitting area 31 and the outer peripheral area 32. Thus, it is suitable for matching the screen printing process and can improve the printing quality. Further preferably, the distance range between the vertex and the first boundary line of the corresponding outward expansion area 35 is 0.1 mm - 0.5 mm.
[0041] In a specific example, compared with the conventional solution without the outward expansion area structure, the embodiment of the present application adopting the above-mentioned outward expansion area structure can increase the ratio of the image edge to the central illuminance from 80% to 85%, significantly improving the overall quality and visual effect of the image.
