Explain the latest developments in automotive display technology
An on-board monitor is a television placed on a car, and an on-board monitor is essentially a car-mounted television. A display that can be used on the same type of sports vehicle in a car, convenient for use in car sports. Car TV is simply the mobile reception of digital TV (different from digital TV). It mainly includes set-top boxes, LCD screens, antennas, and car power supplies. For the convenience of installation and use, a variety of car mobile TV products such as desktop car TVs, bezel car TVs and ceiling-mounted car TVs have been developed.
The main uses of the on-vehicle display include the use of the EV-103 camera for reversing or for public transportation, subway trains, etc. The advertisements on the above are advertised. Now, as long as mainstream products on the market are provided with TVs, voice-over, and readable SD cards, USB and other functions. Even better is like the domestic brand EVERVOX, and some of them have developed alongside on-board computer monitors.
The future will be like what the future of on-board displays will look like, EVERVOX's week always says, “The future of on-board displays will be linked with more cross-age technology, just like 3D now, maybe one day we Will bring the wonderful things brought by 3D technology into our car"
On-board display equipment The on-board display device is usually a liquid crystal display, with an external sound, readable SD card, USB and other functions. This is because the LCD screen is relatively small and easy to install. It can be installed near the instrument panel, on the roof, behind the seat back, or even on the sun visor, which is convenient for use in various situations. In addition, in-vehicle display devices often integrate other functions, such as simple amplifiers, TV reception functions, audio output, etc., and the types and functions are more numerous than TV or computer monitors.
The specifications of the on-board monitor require that the basic specifications of the on-board monitor must provide anti-dust and anti-seismic functions. In terms of temperature, it must be able to withstand the difference of -30°C to +85°C and 120°C, because the liquid crystal in the LCD panel will be at a low temperature. In the environment, there is a phenomenon of freezing, which results in failure to display the screen properly or the ability of the display to be completely destroyed.
Development trend of on-vehicle display TFT liquid crystal display becomes mainstream According to the prediction of car2100, TFT liquid crystal displays rely on their high performance ratio and low cost, resulting in a substantial increase in the ratio of car-configured liquid crystal panels, and will become a vehicle-use audio-visual system and a vehicle-mounted navigation system. The mainstream of the display. However, as the content being broadcast continues to be enriched, the specifications of vehicle-mounted liquid crystal panels are also increasing, such as high-definition display quality, high brightness, large size, wide viewing angle, thin profile, lightweight, high reliability, and low power consumption. Wait. For example, in order to allow users to see the car at a glance, providing higher definition, high-quality images will inevitably become a trend.
In the future, the resolution of the on-vehicle display will be 800×400 and higher, and the screen will also expand within a certain range. Thus, the ambiguity of watching the screen too much due to the small screen during driving is avoided. Further, the single-screen, dual-display LCD panel has also been developed by the industry. This way, a single display panel can provide different image information for the driver's seat and passenger's seat. The driver can watch the navigation screen. The passenger seat passengers can watch video programs or other information and data. The two display devices can independently adjust the screen update rate, resolution and color depth, and can support different applications.
The touch panel has entered the market. The touch panel can provide a more user-friendly operation interface, which is more convenient than using a remote controller to operate a vehicle-mounted navigation system in the front passenger seat. In the future, the automotive display market will be developed.
Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
