Since the premiere of the futuristic Apple Vision Pro, many mocking memes have appeared on the Internet, supporters enchanted by the new possibilities, and skeptics who ask: “who needs it?” Regardless of our opinion, AR goggles from a company from Cupertino are a demonstration of today’s peak of technical thought. That’s why iFixit decided to discuss and disassemble this device. We invite you to take a look at the analysis of their interior.
iFixit has disassembled the Apple Vision Pro, allowing us to take a look at the inside of the popular AR goggles online. Furthermore, we discuss how this futuristic technology works.
You can play Palworld and other PC games on Apple Vision Pro goggles, but it requires knowledge and some effort
The disassembly began with removing the textile band that holds the AR goggles to the face. They are attached to the “glasses” with two latches that can be unfastened with your fingers. The cushions were then removed and the modular speakers removed. To do this, all you had to do was press a button similar to the one used for SIM card trays in smartphones. According to iFixit, the band and speakers are the fastest replaceable components Apple Vision Pro. Unfortunately, dismantling the actual element is very difficult because the parts are very well fitted together and permanently glued. There is a fairly thick layer of protective film on the front transparent glass. Below the first layer of glass there is another, black layer. Only at this point do we discover the external display layer.
Will Apple Vision Pro goggles soon breathe new life into the VR/AR market? Meta strongly believes in this
Then we started disassembling the other side of the AR goggles. The lenses were removed along with two displays, one for each eye. By default, the modules are located on the mounting rail and are connected to the motherboard with a huge number of tapes. It is worth noting how extremely advanced the micro-OLED panels that Apple used in the Vision Pro are. It turns out that the matrix consists of a silicon substrate produced by TSMC, on which Sony has “grown” OLED microstructures. The individual display measures 27.5 mm x 24 mm and each pixel is approximately 7.5 μm x 7.5 μm. After multiplying the values, it turns out that the resolution for each eye is 3660 x 3200 pixels. The pixel density per inch in this case is 3880 PPI, which means that in one pixel of the iPhone matrix we can fit 50 pixels from just one Vision Pro goggle display. Additionally, in one standard pixel of a 65-inch 4K TV, we could cram as many as 2,500 pixels from this micro-OLED matrix.
Right behind the mentioned displays there are fans cooling the micro-OLED panels and the M2 and R1 systems. The motherboard consists of two PCBs connected together by a flexible tape. On one page there is Apple M2 ARM processorwhich is responsible for the operating system and applications, while on the other we find the R1 coprocessor, which is a system that coordinates the operation and calculates data from all cameras, diodes and infrared sensors, as well as LIDAR and TrueDepth. Additionally, there is 8 GB LPDDR5 SDRAM RAM on board from Micron and 256 GB NAND flash memory from Kioxia. Despite such advanced technology, we can still notice some imperfections and delays, especially in a dark environment or with rapid head movements.
Apple is developing two prototypes of a foldable smartphone. However, we cannot count on a quick premiere
Too much iFixit also analyzed the included battery, which is almost impossible to disassemble because a small chisel and hammer were used to open it. Despite the destruction of the aluminum cover, there were three cells connected together inside. They were somewhat similar to those used in smartphones iPhone 15 Plus. A single cell had a size of 15.36 Wh, which suggests a combined capacity of 46.08 Wh. As we know from official data, the capacity of the entire cell is 35.9 Wh, which is about 20% less than the rated value. This is probably because Apple wanted to increase the life of the included cells by limiting the capacity to 80%. It is also worth mentioning that the Vision Pro goggles also receive higher voltage than standard devices with USB-C connectors. Therefore, the product uses a special, large version of the Lightning connector. Ultimately, iFixit rated the repairability of the Apple Vision Pro at 4/10.
