Buying a 200 yuan Head-up Monitor on the Internet has achieved basic functions and met our driving needs.

But if you want to display more content and support more functions, it is really beyond the original factory.

In addition, there are different kinds of head-up displays on the market. If you want to spend a little money to get close to the original factory effect, you still need some tips.

Can the two kinds of heads-up displays compete with the original factory?

At present, there are two main schemes for head-up display in the market, whether it is the original factory or we bought it for 200 yuan.

C-HUD with small screen

1 is a C-HUD with its own small screen. Most cars are equipped with original heads-up displays, which are characterized by turning out or protruding a small transparent screen when in use.

Because the screen is small, even the original one doesn't show much, and the content is quite simple, generally on speed and speed. ...

We installed a connecting cable to read data from OBD, and then the power consumption of this equipment is relatively small, so there is not much risk in getting electricity from OBD interface.

As long as you buy the kind that starts with the car, there will be no obvious damage or problems when you use the battery for a long time.

Some friends may be worried: will the data delay be displayed after I install it? This mainly depends on the equipment.

Because unlike the original factory, it is directly the data given by the car machine. After all, it is an external device that processes data and then displays it on the screen. Theoretically, there is a processing time, and this processing time is a delay.

This size depends on the processing capacity of the device itself.

If you buy it online, I suggest you try it on first. I think the delay is high, so I will return it and change it to a better one. Offline stores are more recommended.

W-HUD is cast on the front windshield.

The second head-up display scheme is a W-HUD directly projected onto the front windshield.

When using it to navigate, it is a bit like: when playing games and doing tasks, you bring your own guide route with HP value.

Here are your skills, too. Can you switch between drinking red drops and blue drops? It's more interesting.

The original car with W-HUD is basically more expensive. Generally, 300,000 to 400,000 cars are available, and the price is not cheap.

Take BMW 3 Series as an example, and choose HUD innovation package 10 100 RMB.

We bought the head-up display for 200 yuan. In principle, there is also a W-HUD, but actually I want to compare it with the original 1 10,000 yuan. "Ha ha", right? This is beyond my ability.

Because this kind of head-up display factory is equipped with a special front windshield, the cost is relatively high, so it costs more than RMB 10.

Ran, Jiang Haibo, and others published the paper "Lighting and Lighting" and "Design of LCD Image Source Lighting System for Automotive Head-up Display".

Internal: In the optical amplification system of W-HUD, the windshield has a great influence on the optical system.

The curved shape will introduce aberration and distortion in reflection imaging, and the sunlight reflected by the system will also cause glare.

Therefore, this kind of head-up display often has special interlayer and coating, and a special high-precision aspheric mirror is designed for the size and curvature of the front bumper.

Look at this process, right? 200 yuan to find someone to see, maybe there are not enough people? Therefore, it is not realistic to change the front gear and match 200.

Therefore, the general treatment method is to stick a special reflective film on the front windshield to improve the display effect.

You can feel such a piece when you don't open it. "alas," my ETC card is there, and it doesn't look good either. Actually, I don't think it's much different to put a screen film on it.

Why do you recommend bringing your own small screen?

The two heads-up displays mentioned just now, although they are all around 200 yuan on the Internet, have similar functions, but 1 C-HUD with its own small screen is still recommended.

Throwing it on the windshield is not stable.

Because its content appears directly on this small screen, the pattern is clearer.

If we install it ourselves, as long as we don't buy the colorful lamp that looks like a jack-o'-lantern, we choose a simpler monochromatic one, which is actually similar to the original factory and elegant.

Even if the light is very strong, you can clearly see the highlighted data.

The second W-HUD, although it can be projected on the windshield, will have a larger area and look more comfortable, but the displayed content has not changed much.

Because the external one, read from OBD, can display navigation, where to turn left, how much speed limit ... This data is not available, what is the relationship with the screen size?

Moreover, there will still be some ghosts after pasting, and the improvement will not be particularly obvious.

The specific effect can be referred to: the mobile phone selects the navigation projection mode and puts it on the front windshield. Looking at that glass, it is almost the same feeling.

In addition, there is glare when the light is strong during the day. Because this film has its own thickness, under a certain angle, if you are not careful, the edge of the film is prone to glare and glare.

Although the impact is not great, I often feel bored when I see it, and occasionally it flashes suddenly. Blindness for half a second and 1 second are also tangled, or I wiped my eyes and shed a tear.

Moreover, our previous video has also been measured, and we also found a problem: once the position of the membrane is fixed, the driver will sit slightly askew and shake his head, or the husband driver will become the wife driver.

The contents of the head-up display may not be in the position of the reflective film. If you can't see it, it will be very uncomfortable. This thing also needs our attention.

The installation of W-HUD is troublesome, which also affects the appearance.

As I said just now, it is troublesome to film the W-HUD projected on the windshield.

Like a cell phone sticker. If you post it yourself, you accidentally leave a bubble in the middle. It's disgusting not to deal with it, right? To uncover the secret of the connection.

There may still be a mark when the sticker is uncovered, and a fingerprint was accidentally stuck. When I tore it off again, a hair fell in, killing me.

I can't stick my mobile phone film well, and I can't stand the window film, so I have to pay attention to this thing.

Song and He also published a paper "Consumer Psychology in the New Era and Its Influence on Marketing" in Business Research.

It said: the psychology of seeking beauty not only shows that consumers are willing to buy more exquisite goods, but also contains the expectation of being recognized by others.

To put it bluntly, we buy things not only to look good, but also to be praised by others, to make ourselves feel better, to praise our good eyes and to buy well, right?

This movie, when we look out from the cab, seems to be just a little dark.

But others look in from the outside, in fact, this piece is quite obvious, just like a patch.

The C-HUD with its own small screen is relatively simple to install, and the advanced configuration of "Oh Yo" will rise. This is a trivial matter. Why didn't my car? It feels different.

200 heads-up displays are generally fine.

So in general, the 200-yuan head-up display bought online is actually no problem to use.

For stable and clear display and quick installation, just buy a "basic model" with a small screen, and don't pursue fancy functions. Each * * * is only 200 yuan.

If the display effect is not good, the whole thing will be discarded. Isn't it not worth the loss?
