Why do apple, Samsung, Xiaomi and others use 2.5D glass displays

these days, many technology companies use the same technology on their smart devices, and are likely to encounter 2.5D glass displays

2.5d glass trend now sounds strange, because there is nothing between two-dimensional and three-dimensional space. However, you need to consider that this term is based on the real design fact that it is one of the trends of environmental protection and energy conservation of building materials, rather than the im head used to sell invalid screen protection devices. Today, most intelligent devices are equipped with such 2.5D glass displays. Many questions are raised in the minds of many people, what is the meaning of this term, what is its difference from traditional displays, what makes it beneficial, and so on

what is a 2.5D glass display? 2.5D is a term used for glass displays, which have a slight curvature at an edge called a contour edge. Remember, the curved edge may not be obvious from a distance, but when you hold the 2.5D glass in your hand, you can see and feel the difference. Do not confuse the 2.5D glass display with the curved display. This kind of display cannot be bent or bent, but has slight curvature at the edge

following the general terminology, the 2.5D glass display screen is a flat 2D screen, but will not have a 90 degree glass edge. It will have an elegant and smooth appearance, making the device more fashionable and soft. There are many distinctive 2.5D glass displays, including Xiaomi's largest, Huawei honor 8, Apple iPhone 7, 7 + and so on. These screens can be further strengthened by Corning Glass

2.5d vs 3D display as described above, there will be a slight curve at the edge of the 2.5D glass display panel. If there are more curves on the edge, the result will be a three-dimensional display in the Samsung Galaxy Note Series. The key difference between the two displays is that the 3D display depends on flexible electronic components, while the 2.5D display does not. How to make 2.5D glass? It is worth noting that there is nothing special about the design or manufacturing method of the 2.5D glass display. The reason is that the actual electronic display components are not bent in the case of flexible displays. 2.5D glass is similar to straight glass panels. However, there are some additional molding processes involved in the manufacturing process. According to the requirements of intelligence, the glass edges are trimmed and smoothed through additional processor layers, and each glass sheet is cut from a larger sheet. It is relatively more expensive, but it can provide a high-quality appearance for the equipment

then the glass is hardened by heating the formed glass in a molten salt solution at a very high temperature. Then it cools rapidly, forcing the glass to compress. These two processes, forming and hardening, are based on stronger structural integrity of the glass, and there will be no risk in reshaping at the end of the process. Models with curved glass displays (such as Galaxy S7 edge) require the transistor backplane and circuit lamp assembly of the display to comply with the curve. Such displays are more complex and quite expensive to produce. The main advantage of 2.5D glass display is that 2.5D glass is purely aesthetic and ergonomic. Especially in intelligence, users will touch and slide on the screen, and it should be smooth, which is very important

another advantage is that in the curved glass edge intelligence, the 2.5 display sample section selection box D glass will be a little higher than the bezel above the display edge. It also ensures that the glass fits the body. In terms of toughness and scratch resistance, manufacturing technology determines its performance. Toughness will vary according to the manufacturing process. 2.5D glass display screen is not stronger or weaker than ordinary flat glass display. The only difference can be seen at the edge of the display. Disadvantages the only significant disadvantage is that users may not be able to obtain third-party products suitable for the shape of 2.5D glass when seeking additional screen savers intelligently, which is precisely due to the curve at the edge compared with flat glass displays. To sum up, we want to say that the 2.5D display may pave the way for some beautiful designs, but this is not a term that can help you make a purchase decision
