On the 10th, Samsung held a galaxy a8s new product release conference in Beijing, and released a new version of the world's leading screen hole digging design. In two days, Huawei nova4's hole digging screen will also be officially unveiled. Today, let's analyze the hole digging screen that is about to become popular and the domestic large aircraft project has driven the development trend of high-end manufacturing industry

first, let's talk about the hole digging screen of Samsung Galaxy a8s. Officials say that this design adopts Samsung's unique structure and packaging technology. It can be seen from the figure that the camera is integrated with the fuselage. There are three layers outside the camera, Blu backlight layer and LTPS liquid crystal layer from inside to outside. Although there are relevant research reports on such polyurethane materials and 2.5D glass panels in China

Samsung's camera is located in the upper left corner, and the screen is made into a hole digging screen by using the "through-hole" technology. In order to achieve this effect, this Samsung Galaxy a8s adopts an LCD screen. At present, there are two types of hole digging screens, "blind hole" and "through hole"

what is "blind hole"? The camera is placed under the screen, and the "through hole" is to make a hole in the screen, and the camera runs through the whole screen. Compared with the "blind hole", the "through hole" is relatively simple in terms of technology, with less screen shielding. The camera does not need to consider the impact of the screen after the light enters from the outside. The "through hole" can effectively reduce the screen layer's shielding of the front camera, so it has more advantages in taking photos to obtain light. Therefore, the solution only needs to consider the perfect connection between the perforated part of the screen and the camera, and the final imaging effect of the screen will not have gaps and unnatural connection. But there is also a problem, that is, the visual integrity of the "through hole" is much worse. Because there is no need to consider the impact of the screen on the camera, the "through hole" punched on the screen will be larger than the camera itself, that is, larger than the "blind hole" hidden under the screen

compared with "through hole", "blind hole" has higher visual integrity, but it is relatively more difficult to realize. Because the camera is hidden under the screen, the light transmittance and color deviation of the light passing through the screen must be considered

in conclusion, the current hole digging screen technology has nothing to criticize. The two hole digging methods have their own advantages and disadvantages

since the first half of this year, panel manufacturers such as shentianma, BOE and csot have been vigorously launching their own hole digging screen schemes, so why is it that they have started to work towards hole digging screens recently? Some of them, such as the elastic elements in the gun barrel and sensors for measuring load and displacement, are provided by the supplier. In addition, there is really no innovation in recent years. Except that the processors are upgraded from generation to generation, there are more and more cameras, and the systems are updated from generation to generation, there are basically no other changes. What should we do if we want to make innovations on the Internet? Manufacturers are targeting the screen and are committed to continuous innovation on the screen. So, there are liuhaiping, meimeijian, shuidi screen, and Now dig holes under the screen. Of course, it does not rule out the lifting cameras launched by oppo and vivo, as well as the Nubian dual screen to achieve a comprehensive screen effect

everything is just pursuing the ultimate comprehensive screen, but whether the screen is a comprehensive screen is really different. Is WDS series liquid crystal electronic tensile testing machine a new material testing machine combining electronic technology and mechanical transmission? What we need to know is that the full screen is just a gimmick. At present, no real full screen has been implemented. What we are doing now is only the solution before the real full screen. However, even though the current technical conditions are not enough, we can only rely on the hardware to present its functions to us. Due to the limited hand conditions, the space left is only a few inches at present. In addition to continuously developing ways to increase the screen share, we still hope that manufacturers can find a way to truly upgrade
