Not long ago, Japanese related TV stations said that they would use the 8K signal to broadcast the 2020 Tokyo Olympic Games, and have begun to try to play 8K programs. Today, the display device's iterative update speed is accelerating. The picture quality of the display screen directly affects the user's perception experience. In order to meet the needs of consumers, the development speed of each display device in screen resolution has been accelerated.
From the earliest QVGA (320 & TImes; 240) to the current mainstream WXGA, 1080P, 2K, 4K, etc., the screen resolution changes witness the progress and improvement of the display industry.
Stagnation means being eliminated. This is the true truth of all industry development. As early as a few years ago, Volkswagen still expects 1080P resolution to appear and be widely used. Today, 1080P, which has become the standard for most display devices, is clearly at a disadvantage in the face of 4K impact, and consumers' appetites follow the development of technology and pursue higher resolution.
The current position of 1080P in the market has shown a downward trend, but from the perspective of the entire display industry, the resolution of all display devices is actually different. In the display, TV and other devices, 4K products have begun to spread, and In the field of projectors and the like, 1080P has been popularized in the field of home projection, but among the smart micro-investment products, 1080P is still very few. This kind of development is inevitably worrying. In the era of high scores, how should smart micro-investment products be faced?
Resolution display effect
Resolution is a parameter that you can often see. It is composed of dots of different colors, which are all magnified by the display device. For a picture with low resolution, the number of points carried is relatively small, while the picture with high resolution has more points in the same area, so the direct distinction of the human eye to different pixel pictures is the picture. Sharpness, because the contrast between the light and dark of the pixels is higher and the detail is more obvious.
At present, the popularity of 1080P products has reached a saturated state. In real life applications, ultra-high resolution is easy to implement, but the source is difficult to come by, so the initial stage of development can basically be regarded as a gimmick. In the field of projection, 1080P still occupies a mainstream position, and even a lot The goal of product line development, such as smart micro-investment.
From the perspective of resolution, the implementation of the resolution upgrade does not seem to be a problem, but currently in the field of domestic smart micro-investment, there are very few products with 1080P. For projection products based on visual experience, the lack of high-definition image quality is a flaw that cannot be ignored. This is mainly due to the fact that upstream chip manufacturers have not provided full HD 1080P chips. Although there are already 1080P chips, many manufacturers still have no choice but to purchase because of the high price.
Resolution and brightness are a pair of "difficult brothers"
The problem of brightness of intelligent micro-projection has always been the focus of consumer discussion, so that many people ignore the resolution in the low-injection of micro-injection. The initial measured brightness of intelligent micro-projection is generally around 100-200 lumens, most of which can achieve an ideal projection effect in an all-black environment. Until now, the brightness of intelligent micro-projection has been significantly improved, close to thousands of lumens. The products have also been published, and the experience has been significantly improved.
Since the advent of the smart micro-projection, it has been mainly small and portable, and the appearance volume is usually light and thin, and one of the main reasons why the brightness is difficult to effectively improve is this. So is the factor that causes micro-investment to the current 1080P product to be rare because of it? Of course, the main reason is the problem of upstream chip manufacturers, but there is indeed a certain connection with the improvement of resolution, because the increase of resolution will inevitably lead to an increase in power consumption during signal input and output, so that the heat generation will increase. It is necessary to have a good heat dissipation for the projector, but the smart micro-projection is just the opposite. It is difficult to improve with the brightness.
Another reason for the resolution of the smart micro-projection is the price. Because smart micro-investment has always been a pro-people route in terms of selling price, the average price is around 2,000 yuan, and improving product resolution will inevitably bring about price increases. However, the current consumer perception of smart micro-investment products has just become popular, so it is reasonable for manufacturers not to rush to test the water.
Editor's summary:
There are many fields involved in the development of display resolution. Each upgrade affects not only product innovation, but also a revolution in visual experience. The improvement of the resolution of intelligent micro-projection still needs to solve many problems. The resolution and brightness are the same as the development direction of smart micro-investment in the future. We look forward to the continuous upgrading of technology, and we also look forward to the rise of high-definition micro-investment in the future. The problem of resolution is not particularly prominent. After all, 1080P chips have appeared. In the future, with the price drop, there will definitely be more high-resolution smart micro-projections. However, it is more difficult to increase the brightness now, and it is necessary to work hard to solve this problem.
ECU Connector Section.
ECU-MEM-CONNECTOR is used to connect the ECU-MEM to the DIAG-LAYER. This part of ODX also links the ECU-MEM-objects with DIAG-COMMS e.g. used to read idents, download or upload the data. It allows an ECU to be flashed using ODX.
There are nearly 100 kinds of connectors used in general automobiles, and hundreds of connectors are used in a single vehicle model. With the increasing demand for automobile safety, environmental protection, comfort and intelligence, the application of automotive electronic products is increasing, which will make the number of Automotive Connector applications increase.
Four basic structural components of automobile connector
1. Contact
It is the core part of automobile connector to complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electrical connection is completed by inserting the female and male contacts. The positive contact is a rigid part, and its shape is cylindrical (round pin), square cylinder (square pin) or flat (insert piece). The positive contact is generally made of brass and phosphor bronze.
The female contact, namely jack, is the key part of the contact pair. It relies on the elastic structure to produce elastic force due to elastic deformation when it is inserted with the pin, and forms a close contact with the positive contact to complete the connection. There are many kinds of Jack structures, such as cylinder type (split slot, shrink mouth), tuning fork type, cantilever beam type (longitudinal slot, 9-shaped), box type (square socket) and hyperboloid linear spring jack.
2. Shell
Also known as the shell, it is the cover of automobile connector, which provides mechanical protection for the built-in insulation mounting plate and pin, and provides the alignment of plug and socket when inserting, so as to fix the connector to the equipment.
3. Insulator
Insulator is also called automobile connector base or insert. Its function is to arrange the contact according to the required position and spacing, and to ensure the insulation performance between contacts and between contact and shell. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials to be processed into insulators.
4. Annex
Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring, sealing gasket, etc. Install accessories such as screws, nuts, screws, coils, etc. Most accessories have standard parts and general parts. It is these four basic structural components that enable the automotive connector to act as a bridge and operate stably.
Application characteristics of automotive connector
From the use purpose of the automobile connector, in order to ensure the better driving of the car, we can divide the reliability of the connector into the sealing property in use and the fireproof performance in the driving of the car. In addition, in the driving of the car, the connector can also show the shielding performance and temperature control performance. In general, when discussing the sealing property of automobile connector, the sealing performance of automobile connector is not only for water.
In this field, the current international management standard is IP67, which is also the highest level in the automotive closure industry. Although the waterproof requirements are different in different parts of the car, many automobile manufacturers will choose IP67 to ensure the airtight performance of their car connectors.
In the driving of the car, power supply is a very important energy source, not only related to the normal work of the engine, but also often involved in the use of power supply in the process of driving. Therefore, in the automotive power system, the automotive connector has different division, between the male connector and the equipment, between the male connector and the cable, between the male and female connector, and between the female connector and cable, there are certain sealing measures that can be implemented.
Sealing ring is a common tool in the sealing performance of automotive connector. This tool can not only achieve the effect of fixing between different hole positions, but also achieve the sealing effect. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment in work. Most of the sealing rings are made of silicone rubber, which is made of liquid silicon and solid silicon after certain chemical changes.
Now the car is in use, electronic circuit technology is an important aspect of the automotive industry, not only in the driver's entertainment, but also in the driver's driving car control system, electronic circuit technology plays an important role in the stable work of the car. In order to ensure the stable work of electronic circuit technology, people have applied a lot of shielding technology in automobile production.
These shielding technologies not only play a protective role in the electronic circuit of the automobile, but also have the ability of anti-interference and anti radiation in the parts of the car. In addition, they can also play a protective role for the stable work of the automobile connector. These can be divided into two types of external shielding and internal shielding.
When using external shielding to protect automobile connector, two identical shielding shells are usually assembled together to form a shielding layer, and the length of the shielding layer can cover the whole length of the connector. On the shielding layer shell, there should be enough locking plate structure to ensure the reliable installation of the shielding layer. In addition, the shielding materials used should not only be treated by electroplating, but also be treated to prevent chemical corrosion.
The future trend of automotive connector
At present, the global automotive connector industry accounts for about 15% of the connector industry. In the future, it is expected to take a larger proportion under the drive of automotive electronic products. In terms of product cost structure, the average cost of connectors used in each car in China is only a few hundred yuan, compared with that of foreign countries
