1. Dot pitch
Populate pitch refers to the distance between the 2 bordering pixel factor on the display screen. If the display size if established, the display screen with a smaller sized dot pitch offers a more clear as well as fine photo. The data of dot pitch stems from the visible location dividing the resolution. For the general LCD, a dot pitch of 0.279 mm can present a penalty and also delicate picture. When it comes to the Lorry LCD Monitors, which generally takes on CF Card Player or Vehicle Hard Drive Player, the dot pitch can totally satisfy the requirement, hence, this specification can be disregarded when it pertains to Lorry LCD Displays.
2. Resolution
Resolution is one of the most vital acquiring parameters of Car LCD Screens. The greater of the resolution is, the better of the picture will be. Given That Vehicle LCD Displays are typically of tiny dimension, it is a respectable LCD if the resolution can reach 720 × 480.
3. Brightness
The optimum brightness of Lorry LCD Monitor is generally identified by the backlight. Currently, the illumination of the LCD varies between 250 ~ 500cd/m2. The greater of the illumination is, the image will certainly be more attractive, nevertheless, the rate will also be greater. Generally, the display with a brightness less than 250cd/m2 is unworthy considering.
4. Comparison proportion
The contrast proportion is additionally of much importance in the direction of Automobile LCD Present. The higher it is, the image will be much more saturated, and also much more stereo. However, the reduced it is, the color will certainly be poorer as well as plain. Normally, the correct comparison proportion is over 200:1, as well as a higher one is around 400:1. If it is reduced than 150:1, you need to pass by it.
5. Viewing angle
Seeing angle refers to the maximum angle from which individuals' eyes can see the screen. The lager, the better. If the viewing angle is little, there will be distortion on the picture if the customer's sight departed a little from the screen, also can't see the image. The suitable watching angle of the Car LCD Display is over 120 level (Straight) as well as the vertical downwards seeing angle is over 70 °. Considering its expense, LCD is generally developed with a upwards seeing angel of 75 ° and a downwards watching angle of 55 °. If we do not provide it technical procedure, this type of screen will squandered its upwards seeing angle and at the very same time, the downwards seeing angle can not satisfy the need. Therefore, the car lcd screen, Full Review, must keep its display screen upside-down to meet the requirement in the vehicle environments.
6. Response time
This criterion is essential, therefore the reality that it establishes if there will be tail phenomena. Response time refers to the time the LCD needs to change from illumination to darkness or the other way around. Generally speaking, the much shorter the action time is, the far better. If the response time is short, people will not run into blur or sticking around traces when they are considering the moving images. According to the action time of the eyes, there will be slow-moving relocating photos if the response time mores than 100 milliseconds. Presently, the standard feedback time varies between 50-80 milliseconds, and some high-grade LCD's reaction time varies in between 25-30 nanoseconds. If the action time is at 80 nanoseconds, there won't be trailing phenomena. What deserves noticing is that reaction time consists of rising time and also coming down time, while some makes only indicate rising time or descending time, which might misdirects our consumers.
7. Color
When choosing Automobile LCD Displays, the expressiveness of the color is the most vital specification. As we all know, any type of color of the nature is comprised of three standard shades, namely, red, eco-friendly as well as blue. Each independent pixel color of the LCD is controlled by the 3 basic shades. The majority of the LCD's standard shade reaches 6 digits, that is 64 sorts of efficiency indications, after that each independent pixel has 64 × 64 × 64= 262144 type of shades. A bulk of the LCD has only 262,144 colors, even the high-grade ones. The 32 digits( 16,777,216) labeled by the manufacturers comes from interpolation or dithering formula, which is far poorer than the actual 32 digits. The display screen can provide a great color if it reaches 26M.
The above stated are some vital specifications when choosing a LCD, and also absolutely, there are some other criteria as well as methods to keep an eye on the high quality of the display screen. However, you will get a satisfying LCD product if you keep the above 7 vital criteria in mind.
1. Dimension
Currently, 3 sizes are available for the coaches: 15", 17", 19", 26". The selection of the size should be the primary step of selecting Vehicle LCD Screen. If it's large, it will certainly lead to not only waste in financial investment, however the space as well, therefore, the choice of dimension is extremely important. Typically, the if the train's size is less than 7 meters, it ought to be 15", as well as 17" or 19" for the coach of 7 meters to 10 meters, as well as for the trains longer than 10 meters, it ought to pick 17" or 19". Some top-quality trainers might pick 26", as well as sleeper train normally select 15".
2. Installation
Long-distance trainers normally select hands-on flip monitors, consisting of backward-flip as well as forward-flip. Top-quality instructors adopt motorized flip screens, making the inside a lot more extravagant. Bus advertisers should choose set installation, therefore it can not be folded up once it is mounted, to ensure that the display is constantly on.
3. Voltage
Generally, gas engine vehicle is 12V, and also diesel engine lorry is 24V, as well as we need to choose equivalent items. We do not always have to choose so-called 12,24 V interchangeable items, on account of the truth that it might result in several issues. Currently, the regular residential and abroad Lorry LCD Screen manufactures all embrace 12V, 24 V separated style.
4. LCD
To get a brand-new Automobile LCD Screen is the biggest wish of every customer, nonetheless, there are great deals of revamped used Automobile LCD Screens of small cost and also absolutely, the top quality of the product can not be guaranteed. Here, I will provide you some suggestions on differentiate whether the screen is old or brand-new:
At present, the mainstream dimension are: 15"( 4:3), 17"( 4:3), 19"( 16:9). If you see various other dimensions with quite reduced rate, then you ought to be careful.
On top of that, we must observe the brightness. We ought to look out if the illumination is as well high or also reduced. 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 also reduced, as well as overhauled one if the brightness is too expensive. It's absolutely nothing of a key to set up fluorescent tube on old screens.
Lastly, we need to have a look at the port. If the recently made Vehicle LCD Screen is simulated port, then you must pass by it, given that LVDS digital port has been the mainstream port because three years earlier.
5. Upside down Display
Since downwards viewing angle is of much relevance to the car displays, upside down display technology is additionally crucial. You can change on the display as well as make a comparison of the downwards and also upwards, then you will understand whether it is an excellent one or poor.
6. Explosion-proof
Because Lorry LCD Monitors are made use of in public areas, the security of the LCD is of much value, and also pick the explosion-proof item is the front runner when purchasing the Vehicle LCD Monitors, particularly in buses. In enhancement, you ought to attempt to pick HD products preferably, given that it truly presents fine pictures. Besides the reputable first-class items, we after-sales solution is an additional crucial element. You ought to pass by the constructed products, because it has genetic problems in there design, although it assures a 3 months service warranty.
