With the release of Apple's Vision Pro, iFixit, a well-known disassembler known for disassembling fashionable IT products and providing Apple's repair manuals, has released the world's first teardown of Vision Pro, and every circuit board, every screw, and every camera is unreservedly presented in front of everyone.
From the exterior design, the front of the Vision Pro looks like a pair of ski goggles, and the front display actually has four layers: a glass cover, an OLED outer screen lens, a lens layer, and the OLED display itself.
The first layer is a curved 3D laminated polished glass panel of fully curved glass, weighing about 34 grams, and its exclusive supplier is Lens Technology, one of the domestic fruit chain giants.
From the original glass to the finished product, the cover glass needs to go through a series of processing and production processes such as cutting, CNC, polishing, ultrasonic cleaning, vacuum forging die, tempering, silk screen printing, etc., and any problems in the processing link will lead to the screen quality is not up to standard; WhileThe shape (curved surface) and material particularity (transparency) of the cover glass have high requirements for the optical stability and depth of field of the vision system, you can consider using itHigh-precision sensor based on point-line spectral confocal technologyTake a specific measurement.
The second layer is the OLED outer screen lens on top of the biconvex lens layer on the surface of the screen.
The thickness of the lensIn addition to affecting the calculated angle of the picture projection, it will also directly affect its weight and thus the overall weight of the device, thereforeThickness inspection of VR AR spectacle lensesIt has gradually become one of the basic operations of equipment manufacturers and can be consideredHigh-precision sensor based on line spectral confocal technologyTake a specific measurement.
This is followed by the third layer, the biconvex lens layer, which is used to stretch and enlarge the image displayed on the screen so that it fills the entire Vision Pro.
Why does the face displayed by Eyesight look strange, iFixit analyzes it from the level of display principle.
First, Vision Pro will generate your face through the internal camera and sensors, then VisionOS will "slice and interpolate" the face, and then render it on the EyeSight display, and the image will pass through a layer of lenses and then a layer of lenses, and finally achieve the visual effect of a 3D face image.
As can be seen from the slice of the lens layer**, the structure of this layer of lenses is very fine, and the width of each "wave" type structure is less than 05 mm; WhileThe quality of the lens will directly affect the display effect, given its transparency characteristics, wave structure, micron-level width, and other characteristics, recommendedHigh-precision sensor based on line spectral confocal technologyPerform a visual inspection.
Finally, there is the Micro OLED screen composed of Sony's 4K Micro OLED screen Yujing Optoelectronics' 3P Pancake solution, which has up to 23 million pixels, making the resolution of a single eye more than 4K.
At present, Sony's Micro OLED screen production yield is only about 5%, which not only leads to the price of 2 Micro OLED panels as high as 700 US dollars, but also limits the number of panels it can actually supply this year, estimated at about 1 million pieces. Obviously, Micro OLED is undoubtedly the key component that has the most decisive impact on the current Vision Pro when it comes to reducing cost efficiency and expanding shipments.
Transferring tiny LED lamp beads to the base on a PCB board or glass substrate is a key process in the production process of Mirco Mini-LED products. As the volume of lamp beads is getting smaller and smaller, the appearance inspection of incoming substrates through manual visual inspection can no longer meet the existing testing needs
In order to quickly screen out qualified substrates, improve the yield of mini-LED products in automated production, reduce defective products and reduce the overall production costHigh-precision visual inspection of the mini-LED baseIt's becoming more and more important.
Product Introduction
3D Line Spectral Confocal Sensor & Point Spectral Confocal Displacement Sensor.
Hypersen HPS-LCX seriesIt is a non-contact optical precision measurement sensor based on the principle of spectral confocal method, which has the characteristics of fast detection speed, high imaging resolution and strong material adaptability. The product uses line-scan CMOS imaging to realize the 3D feature analysis of the appearance of the measured object, which breaks through the limitations of traditional detection methods in technology, and the measurement process is not affected by the intensity of reflected light.
Hypersen HPS-CF seriesIt is a high-end optical precision detection sensor based on the principle of spectral confocal method, which uses non-contact measurement method to obtain the surface distance value data of the object to realize the surface profile and defect detection and analysis of the measured object.
It effectively solves the problem of high-precision appearance inspection of transparent body, highly reflective mirror, black rubber and other materials in the industry, and is suitable for first-class testing applications in the fields of 3C electronics, semiconductors, automotive electronics, medical treatment and scientific research.
