Nowadays, the electronics industry is booming, the car LCD screen has developed rapidly in just a few years, and the choice of the car display screen has gradually evolved into a kind of knowledge, so when the project uses the car LCD screen, how to select it?
1. Selection of On-board Screen Size
The size of the car screen needs to be selected according to the size, space and positioning of the car.
2. Selection of installation mode of vehicle-mounted screen
A. Long-distance passenger transport usually uses some products in the form of manual turnover. Among them, there is also a difference between front turnover and rear turnover. Luxury buses generally use electric turnover products, which will make the whole car look luxurious and high-end.
B. The interior of the bus should be fixed. When the LCD screen is installed in the bus, passengers can not fold or turn the LCD screen at will, so that the screen will always be in a state of display.
C. There are many places where screens are used in ordinary family cars, depending on the whole structure.
3. Selection of on-board screen voltage
Generally, the voltage of gasoline engine models is 12V, and that of diesel engine models is 24V. When selecting the voltage, it is necessary to select according to the specific voltage endurance of the LCD screen. Generally, the statement that 12V and 24V are universal is not agreed, and it is easy to fail. At present, the vehicle LCD screens produced by more formal manufacturers are generally 12 V and 24 V.
4. Selection of new and old on-board screens
Everyone should like the new car LCD screen, but in the current market, there are many refurbished screens, which disrupt the competition of the whole market and confuse the choice of some consumers. Generally, the price of second-hand screens renovated in the market is very low, and the quality of products is not guaranteed, so we must have the ability to distinguish the old and renovated screens.
A. The general sizes of mainstream screens on the market are: 7-inch, 8.4-inch, 5.6-inch, 15-inch (4:3), 17-inch (4:3), 19-inch (16:9 widescreen). If there are other sizes, and the price is particularly low, we need to pay attention to the quality of the screen.
B. Pay special attention to the brightness of the screen when it is too low or very high. So far, the brightness of the 15-inch screen is generally between 250-400, and that of the 17-inch screen is generally between 250-500.The 19-inch is generally between 300 and 550. If it's too low, it's definitely an old screen, and if it's too high, it's probably a refurbished screen. At present, it is no secret that old screens are added with light tubes. For those old screens with modified tubes, some monochrome images can be played, and light leakage can also be seen.
C. The interface for watching the screen. If the on-board LCD screen is still an analog interface, there is no need to select it. The LVDS digital interface has been a mainstream interface for more than three years.
5. Selection of inverted screen
Because of the limitation of environmental conditions, the vehicle LCD screen has very special design requirements for the downward viewing angle, so now manufacturers have designed a screen inversion technology, how to judge whether this LCD screen can be inverted, just light its product, and then compare it up and down to distinguish it.
6. Explosion-proof treatment
Vehicle LCD screen needs to be used in public places, so we must protect it well, safety first, so we must choose the kind of explosion-proof treatment when we choose, especially in buses and passenger cars, the crowd is relatively concentrated, for the sake of safety, we must choose the explosion-proof treatment.
When users buy screens, they usually try to choose the products with high-definition lines, so that the images they play are clearer. After-sales service is also very important, do not choose assembled products.
