Standing on the edge of the narrow frame, let's imagine the future of screen technology

Huawei's full screen notebook has recently set off a small upsurge. Now, the full screen has become one of the future trends of notebook screens. It not only meets people's needs for visual effects and efficient life, but also unlocks more potential interaction methods

day after day, new technological innovations will also burst out because people have new needs, and the future interactive experience and screen effect will only be better and better

the inevitable result of the call of the times

a major feature of our era is the pursuit of a fast-paced and efficient life. The simple and elegant design style is the mainstream of our era

the narrow border and even the full screen are applied to notebook screen design under such an environment. In 2014, the thickness of the border of most notebooks was still a full centimeter thick. After the blowout of narrow border notebooks in 15 and 16 years, the border of notebooks became narrower and narrower

nowadays, even if the current advertising law without a full screen was implemented in 1995, notebook manufacturers are trying their best to launch products such as "micro frame" and "ultra narrow frame"

before 2012, the border of XPS looked very thick. The 09 XPS 13 had a border thickness of no less than one centimeter. After that, Dell has been trying to increase the screen share on XPS. In 2012, XPS 13 has reduced the border to less than one centimeter

in the past 15 years, the frame of XPS 13 has been close to the screen share of full screen - now the full screen notebook is an inevitable result of the general trend

large screen brings a better experience, and a more efficient use experience is exactly what people need. The reason why people like the design of the comprehensive screen is not only the aesthetic imperceptible reason, but also the visual impact of the large screen brought by the comprehensive screen, multi-threaded processing of various transactions, and browsing more information at the same time, so that they can complete their work more efficiently

for users who experience audio-visual entertainment while brushing social networks, small screen naturally cannot browse multiple information sources at the same time. Large screen can not only bring extreme visual impact when entertaining in full screen, but also enjoy multiple information sources at the same time when using multiple windows, and improve the overall visual experience

how is the narrow border achieved

the increase in the proportion of screen size is not as simple as it seems. The thickness and manufacturing technology of the screen are closely related to whether it can be safely used. As a mobile electronic product, notebook naturally needs a safe and reliable screen

from the initial thick circle of screen frame to the emergence of comprehensive screen, it has not only experienced changes in public aesthetics, but also a victory in technology accumulation and manufacturer promotion

because the liquid crystal is a liquid crystal, it is poured into the panel interlayer. In order to prevent its leakage, it is necessary to seal the frame - and because the dripping of liquid crystal and the bonding of frame colloid are synchronous in the production process of liquid crystal screen, the narrower the plastic frame, the higher the accuracy requirements of liquid crystal dripping

the existing liquid crystal display device mainly includes two parts: the backlight module and the liquid crystal panel installed above the backlight module. The backlight module specifically includes LED light, rubber frame, mouth glue, light guide plate, brightening film and astigmatism film. When working, the LED light is emitted by the LED light, scattered by the light guide plate, and then concentrated by each layer of diaphragm, so that the whole surface of the backlight module is evenly illuminated

the glue frame is located at the periphery of the light guide plate, and the backlight module uses the structure of the glue frame and the word of mouth glue to fix the LCD panel above it - at present, the main way to realize the narrow frame design is to reduce the frame width by reducing the width of the glue frame (so the width of the side frame is first affected by the frame glue coating process)

but the waste of plastic frame and liquid crystal surface can also be degraded into non polluting objects; Third, because of its weak crystallization ability, the edge of the activearea (AA) of the board must always keep a certain distance (usually at least 0.75mm) to prevent the occurrence of light leakage at the large viewing angle of the display edge, which also limits the extent to which the frame can be narrowed to a certain extent

grid line layout

the width of the frame is not only related to the frame adhesive coating process, but also related to the layout of the screen grid drive circuit

there will be flat lines and circuit boards under the LCD screen. This circle of flat lines is not only responsible for transmitting image data, but also for driving the action of filter switches of each pixel, so as to display images of different colors - the traditional layout method is direct layout

the width of the screen border is related to the width of the grid line and the number of pixels on the screen (that is, the resolution). The greater the resolution, the greater the width required for this circle of grid lines. Therefore, improving the layout of grid lines has become an important method to reduce the thickness of the border

it consumes machine time and network bandwidth capital when collecting pages

the problem is

it is true that as long as the manufacturing process is improved, technical difficulties will inevitably be involved

there are two main difficulties in improving the plastic frame process. The first is the control of light leakage - the realization of ultra narrow frame requires the width of the frame glue to be reduced, but if the width of the frame glue is too narrow, it is easy to have the problem of light leakage, which needs to be handled carefully

to achieve a detailed treatment effect, we will encounter another difficulty - the current glue applicator has been imperfect in the treatment process of high viscosity frame glue

in the process of large-scale production, the pursuit of meticulous processing effect will undoubtedly increase the cost (so manufacturers who can produce narrow frame/full screen notebooks should still have certain strength)

as for the grid line layout mode, it also faces the problem of rising costs - the new grid wiring mode requires workers to skillfully operate the new connection mode, which increases the labor cost required for production to a certain extent - in other words, all these require money

it will be better in the future

the design of narrow frame not only effectively reduces the thickness of screen frame and improves the proportion of screen, but also improves the mobility of the whole machine, making the notebook lighter and thinner

this is also one of the reasons why thin instinct is so amazing today - a better and more comfortable life has always been the pursuit of people, and major manufacturers are also secretly working on it. In the future, such products will only be more and more

the development of comprehensive screen also reflects the subtle change of notebook interaction mode. From the computer without mouse pure code at the beginning to the current comprehensive screen and touch screen operation interaction mode, it reflects the change of people's use of notebook

in the future, people will certainly not be satisfied with writing only on the size of the screen, and directly carry out a variety of gesture operations on the screen. New screen technology, VR, holographic imaging may become a new way of notebook imaging and interaction

maybe one day, the notebook we use will no longer have the traditional screen. It is also possible to use it directly in the air as long as we take the thin body to various occasions
