Introduction to Automotive Displays
There are two types of car monitors. One is a TV placed on a passenger car, which is essentially a car TV. The other is a small size car monitor with 3.5-inch, 4.3-inch, 7-inch, and 9-inch. Generally, there are two channels of video. Input, one way can be used for car DVD, the other way is used for reversing video car camera, and some also have MP5 video playback and Bluetooth function, which can be used on the display of similar sports tools in cars, which is convenient for use in car sports. Car TV is simply the mobile reception of digital TV (different from digital TV), which mainly includes set-top boxes, LCD screens, antennas, and car power supplies. In order to facilitate the installation and use, various types of mobile TV products have been developed, such as desktop car TVs, baffle car TVs, top-suction car TVs, and rearview mirror displays.
Product definition
The main purpose of the car monitor is to add a car camera for reversing or for advertising on buses, subways, trains, etc., as long as the mainstream products on the market have functions such as TV, external sound, readable SD card, and USB. Some products have developed in the direction of on-board computer monitors,
In the future, car monitors will be connected with more cross-age technologies, just like 3D. Maybe one day we will bring the excitement brought by 3D technology into our car.
display screen
Vehicle-mounted display devices are usually LCD screens, with external sound, readable SD cards, USB and Bluetooth, and other functions. The on-board display of the onboard navigator has an incoming call voice reporting function. This is because the size of the LCD screen is relatively small and easy to install. It can be installed near the dashboard, on the roof, behind the seat back, or even on the sun visor. Used in various situations. In addition, vehicle-mounted display devices often integrate other functions, such as simple power amplifiers, TV receiving functions, audio output, etc., with more types and functions than TVs or computer monitors.
Specification requirements
The basic specifications of car monitors must provide anti-dust and anti-vibration functions. In terms of temperature, they must be able to withstand the high and low-temperature difference of -30℃~+85℃ and 120℃, because the liquid crystal in the LCD panel will appear in a low-temperature environment. The phenomenon of freezing, causing the screen to be unable to be displayed normally, or the ability to be displayed is completely destroyed.
development trend
TFT LCD has become mainstream
According to forecasts, TFT liquid crystal displays, due to their high-performance ratio and low cost, will cause a significant increase in the ratio of cars equipped with liquid crystal panels, and will become the mainstream of car-mounted audio-visual systems and car-mounted navigation system displays. However, as the content to be played continues to be enriched, the specifications of automotive LCD panels are also increasing day by day, such as high-definition display quality, high brightness, large size, wide viewing angle, thinner, lighter weight, high reliability, low power consumption, etc. Wait. For example, in order to make it clear to users when driving a car, it is bound to become a development trend to provide higher definition and high-quality images.
In the future, the resolution of on-board displays will be 800×400 and higher, and the screen will be expanded within a certain range. Thus, avoiding the embarrassment of excessively focusing on watching the screen due to the small screen during driving. Furthermore, a single-screen dual-display LCD panel has also been developed by the industry. In this way, a single display panel can provide different image information for the driver’s seat and the passenger’s seat at the same time. The driver can watch the navigation screen, The passenger in the passenger seat can watch video programs or other information and materials. The two display devices can independently adjust the screen update rate, resolution, and color depth, and can support different applications.
Touch panel enters the market
The touch panel can provide a more convenient operation interface for the user, which is more convenient than using the remote control in the passenger seat to operate the car navigation system in the past. In the future, the car display market is bound to develop.
Vehicle monitors are generally divided into several styles
Rearview mirror display. Sun visor display/car mount display Folding display
There are also different operations for monitor the use
Touch screen: Generally the price is more expensive
Buttons or remote control are more and more cost-effective
product features
High definition, undistorted color, can provide a high-quality picture
Remote control operation is more convenient
Simple and convenient installation does not damage the car body
Specially customized for in-vehicle video display, with good shock resistance
Good image smoothness, no smear
In summary, this article has explained the car monitor for everyone, I believe that everyone will have a deeper and deeper understanding of the car monitor, and I hope this article can be of greater reference value for readers.
