LCD screens have a longer lifespan, lower energy consumption and lower cost than CRTs. LCD screens are used in medical equipment, money counters, automotive instruments, etc. Today, I will talk to you about how to choose a suitable vehicle-mounted Liquid Crystal Display. 1. The choice of the size of the car LCD screen: it needs to be selected according to the size, space and positioning of the car. 2. The choice of the installation method of the vehicle LCD screen. A. Long-distance passenger transport usually adopts some products in the form of manual flipping. Among them, there is also the difference between front flipping and rear flipping. Luxury buses generally use electric flipping products, which will show the decoration of the entire car. luxury. B. The interior of the bus should be a fixed installation method. After the LCD TV is installed in the bus, passengers cannot fold or flip the LCD TV at will, so that the TV is always in a state of display. C. There are many places where screens are used in ordinary household cars, and it depends on your entire structure! 3. The choice of TV voltage: General gasoline engine models are 12V voltage, diesel engine models are generally 24V, when choosing the voltage, you need to choose according to the specific voltage tolerance of the LCD TV, generally 12V, 24V This general statement is disapproved, and it is prone to failure. Now the car LCD TVs produced by more regular manufacturers are generally 12V and 24V divided voltage. 4. Regarding the selectivity of the vehicle-mounted Liquid Crystal Display Module: Everyone should like the brand new vehicle-mounted LCD TV, but there are many refurbished TVs on the market, which disrupts the competitiveness of the entire market and confuses the choices of some consumers. . Generally, the price of refurbished second-hand TVs in the market is very low, and the quality of the products is not guaranteed, so it is necessary to have the ability to identify old and refurbished TVs. A. The general sizes of mainstream car LCD screens on the market are: 7 inches, 8.4 inches, 5.6 inches, 15 inches (4:3), 17 inches (4:3), 19 inches (16:9 widescreen). If there are other sizes, and the price is particularly low, you need to pay attention to the quality of the screen. B. Special attention should be paid to when the brightness of the screen is too low or high. So far, the brightness of the 15-inch is generally between 250-400, the brightness of the 17-inch is generally between 250-500, and the brightness of the 19-inch is generally between 300 -550 between. If it is too low, it must be an old screen, if it is too high, it may be a refurbished screen. At present, it is no secret that old screens and lamps are added. For those old screens with modified lamps, some monochrome images can be played, and light leakage can also be seen. C. The interface for viewing the screen. If the current car LCD screen is still an analog interface, there is no need to make a selection. The LVDS digital interface has already become the mainstream interface three years ago. 5. The choice of the inverted screen: The vehicle LCD screen has special design requirements for the lower viewing angle due to the restrictive environmental conditions, so the current manufacturers have designed a screen inverted technology, how to judge whether this LCD screen can be inverted. , you only need to light up its product, and then you can distinguish it after comparing it up and down. 6. Explosion-proof treatment: The car LCD screen needs to be used in public places, so it must be protected well, so we must choose the kind of explosion-proof treatment when choosing, especially on buses and passenger cars. The crowd is relatively concentrated, for safety reasons, so be sure to choose explosion-proof ones.
