As indicated by its name, Vehicle LCD Screen takes on LCD as its display screen. Comparing to the traditional CRT lorry monitors, Vehicle LCD Screens has evident technical benefits. As the cost of LCD decreased in 2008, presently, Lorry LCD Displays has entirely replaced the conventional CRT lorry monitors.

Vehicle LCD Monitor has the following recognized functions: tiny volume, light, entirely flat, low consumption, no glittering as well as no distortion. Prior to choosing an Automobile LCD Monitor, we need to have a look at the standard criteria.

1. Dot pitch
Dot pitch describes the range between the 2 neighboring pixel point on the display screen. The screen with a smaller sized dot pitch provides a clearer as well as fine picture if the display dimension if set. The data of dot pitch originates from the visible location separating the resolution. For the general LCD, a dot pitch of 0.279 mm can present a fine and also delicate image. When it comes to the car display manufacturers LCD Screens, which normally takes on CF Card Player or Automobile Hard Disk Gamer, the dot pitch can completely meet the demand, therefore, this criterion can be disregarded when it comes to Vehicle LCD Screens.

2. Resolution
Resolution is among one of the most essential getting specifications of Vehicle LCD Displays. The greater of the resolution is, the far better of the picture will certainly be. Because Vehicle LCD Displays are usually of small size, it is a respectable LCD if the resolution can get to 720 × 480.

3. Brightness
The maximum illumination of Vehicle LCD Monitor is usually established by the backlight. Currently, the illumination of the LCD varies in between 250 ~ 500cd/m2. The higher of the brightness is, the image will be more stunning, nevertheless, the cost will certainly additionally be higher. Generally, the display screen with an illumination less than 250cd/m2 is unworthy thinking about.

4. Comparison ratio
The comparison ratio is also of much importance in the direction of Automobile LCD Show. The higher it is, the image will be extra saturated, and more stereo. However, the lower it is, the color will certainly be poorer as well as plain. Usually, the proper comparison proportion is over 200:1, and also a greater one is approximately 400:1. If it is less than 150:1, you must pass by it.

5. Watching angle
Checking out angle describes the optimum angle where people' eyes can see the display. The lager, the much better. If the checking out angle is small, there will certainly be distortion on the picture if the customer's eyesight drifted a little from the screen, also can't see the image. The suitable watching angle of the Automobile LCD Screen is over 120 level (Horizontal) and the upright downwards checking out angle is over 70 °. Considering its cost, LCD is usually developed with a upwards watching angel of 75 ° and also a downwards watching angle of 55 °. If we do not give it technical procedure, this sort of display screen will squandered its upwards checking out angle as well as at the exact same time, the downwards checking out angle can not satisfy the requirement. For that reason, the Automobile LCD Screen must maintain its display upside down to satisfy the requirement in the vehicle environments.

6. Feedback time
This specification is very important, on account of the fact that it determines if there will be tail phenomena. Reaction time describes the moment the LCD requires to switch over from illumination to darkness or the other way around. Generally speaking, the shorter the action time is, the much better. Individuals will not come across blur or remaining traces when they are looking at the relocating photos if the reaction time is brief. According to the reaction time of the eyes, there will certainly be slow-moving moving pictures if the response time mores than 100 nanoseconds. At existing, the common feedback time varies in between 50-80 milliseconds, as well as some top-quality LCD's response time ranges between 25-30 nanoseconds. If the action time is at 80 milliseconds, there won't be tailing phenomena. What is worth observing is that feedback time includes ascending time and also descending time, while some produces only imply rising time or coming down time, which might misleads our customers.

7. Color
The expressiveness of the color is one of the most vital criterion when choosing Lorry LCD Screens. As we all know, any kind of shade of the nature is made up of three basic colors, namely, red, blue and eco-friendly. Each independent pixel shade of the LCD is managed by the three fundamental colors. Many of the LCD's fundamental color gets to 6 digits, that is 64 sorts of performance signs, after that each independent pixel has 64 × 64 × 64= 262144 kinds of colors. A bulk of the LCD has just 262,144 shades, also the state-of-the-art ones. The 32 digits( 16,777,216) labeled by the manufacturers originates from interpolation or dithering formula, which is far poorer than the actual 32 numbers. The display can provide a good shade if it reaches 26M.

The above discussed are some important parameters when selecting a LCD, and most definitely, there are some other parameters and also techniques to check the quality of the display screen. Nonetheless, you will certainly obtain a gratifying LCD item if you maintain the above 7 crucial parameters in mind.

Next, we will have a look at just how to choose the Car LCD Monitor

1. Size
Currently, three sizes are available for the coaches: 15", 17", 19", 26". The option of the size must be the initial step of choosing Automobile LCD Screen. If it's extra-large, it will lead to not only waste in investment, but the area also, consequently, the selection of dimension is extremely essential. Generally, the if the instructor's length is less than 7 meters, it should be 15", and 17" or 19" for the trainer of 7 meters to 10 meters, and also for the instructors longer than 10 meters, it needs to select 17" or 19". Some high-grade instructors may choose 26", as well as sleeper instructor typically pick 15".

2. Setup
Long-distance trains generally select hands-on flip monitors, including forward-flip and also backward-flip. Top-quality instructors take on mechanized flip screens, making the inside more glamorous. Bus marketers must choose set installation, therefore it can not be folded up once it is installed, so that the monitor is constantly on.

3. Voltage
Generally, gas engine lorry is 12V, and diesel engine automobile is 24V, and we must select corresponding products. We do not always need to choose supposed 12,24 V interchangeable items, on account of the reality that it might lead to many issues. Currently, the regular domestic and also abroad Automobile LCD Screen makes all take on 12V, 24 V apart design.

4. LCD
To get a brand name brand-new Vehicle LCD Screen is the most significant desire of every client, nonetheless, there are great deals of spruced up pre-owned Vehicle LCD Screens of small cost as well as certainly, the high quality of the item can not be guaranteed. Here, I will offer you some pointers on distinguish whether the display screen is brand-new or old:

Presently, the mainstream size are: 15"( 4:3), 17"( 4:3), 19"( 16:9). If you see other dimensions with pretty small cost, after that you need to beware.

On top of that, we need to observe the illumination. If the illumination is also reduced or too high, we need to be alert. The illumination of 15" varies between 250-400, 250-500 for 17" and also 300-550 for 19". It is 2nd handed if the brightness is as well reduced, and spruced up one if the brightness is too expensive. It's nothing of a key to set up fluorescent tube on old display screens.

Ultimately, we need to take a look at the port. If the recently produced Vehicle LCD Monitor is simulated port, after that you should not pick it, considering that LVDS digital port has actually been the mainstream port since 3 years earlier.

5. Upside down Display
Given that downwards seeing angle is of much significance to the vehicle screens, upside down display technology is additionally important. You can activate the screen and also make a comparison of the downwards and also upwards, then you will certainly know whether it is a great one or poor.

6. Explosion-proof
Since Vehicle LCD Displays are used in public places, the protection of the LCD is of much value, as well as select the explosion-proof item is the first selection when purchasing the Lorry LCD Monitors, specifically in buses. Furthermore, you need to try to pick HD products when possible, considering that it actually offers great photos. Besides the qualified excellent products, we after-sales solution is one more key aspect. You should pass by the constructed items, since it has genetic issues in there style, even though it promises a 3 months warranty.
