Complete the guide to this technology

Call makers are always looking to innovate, with new designs, features, and developments. Cameras are one of the most developed forums, there are many changes in the market. Technology that has been making a lot of noise for a few months is now available using the camera at the bottom of the screen. In fact, many types of work on Android are working.

Although it has been talked about a lot over the months, the truth is The concept of the camera at the bottom of the screen is unknown for many users. So, below we gather everything we know about this technology and what we can expect from the market.

What is the camera at the bottom of the screen

As its name implies, it is a form of the camera is placed at the bottom of the screen from the phone. The sensor is located at the bottom of the device screen, so we can't see it. Or in order for this sensor to function, a series of very important requirements must be met.

The camera must be flexible and the screen must it becomes obvious when we take a picture, in addition to letting go of light. There should also be continuity between the entire screen and the location of the lens. In addition, the software must be compatible as well, in order to improve image conversion.

How this might be a little different. Xiaomi for example has introduced into its ownership the small transparent screen that the camera has just mentioned. As a result, the sensor has the ability to capture the external image, in addition to controlling the amount of light entering the sensor, thus obtaining better images. While other models like OPPO use a different program on their on-screen camera.

The use of this type of camera will allow manufacturers are introducing new construction, models are very close to the concept of the whole screen. You will no longer need to save space on the panel that is set to position the sensor, either by a notch or a hole. It thus opens up new possibilities for telecommunications projects, something that is needed today.

What products work in it

To date, many products have been patented and have produced their own programs. OPPO and Xiaomi are the two most effective products creating a camera at the bottom of the screen. They have both introduced or shown us how these applications will work on their phones. So you can see that they are more advanced than other products in the industry.

Huawei is another hybrid and the use of this type of camera, as can be seen in one of his rights. Redmi will also have another device that uses the camera at the bottom of the screen on one of its phones, which was its purpose at least, though its CEO said in an interview that it was almost impossible.

Although these products are the subject of many articles, Samsung was a pioneer, by making patents at the end of the year 2018 for the camera system at the bottom of the screen, so far not much is known. The Korean product may still work today, but at least we know it's a concept they've been considering using on their other phones.

For now unknown or other products Android works by using these types of cameras. It would be unusual for a lot to be available, or to add more products to this list, something we will definitely find in months.

Why does it take so long to get there?

We have heard for months about the concept of the camera under the phone screen. OPPO and Xiaomi have officially introduced such technology, but so far no phone was issued to use this type of camera. There are several reasons for this, those that delay their arrival in the market.

For precisely two reasons, at least at the general level, that restrict the use of the camera at the bottom of the screen has become commonplace in the Android phone market.

Two main reasons

One of the biggest fears when the announcement of this technology has come true: Image quality is compromised. OPPO itself had to admit that the quality of the images was worse. This is a problem that must be solved before even considering starting production of this type of sensor or phone. So far it hasn't happened, so this causes you to wait.

Another major problem is the production itself. In contrast to the standard sensor and standard displays, the mass production of these types of cameras under the display cannot be done yet. There are two reasons why this happened, namely the collection of pixels on the screens and the transfer of light:

1. Maximum pixel: Screens today have a lot of pixels, something that makes it difficult to fit the camera at the bottom of the screen, because they block too much light.
2. Low light transmission: This pixel restriction directly affects the transmission of negative light through the screen, making the sensor's output much lower than it would otherwise receive in normal conditions.

Because on today's screens, pixel sizes are about 400 on average, Light transmission is low, it causes worse images. When that PPI value is reduced and the light is transmitted, there is a gap between the camera area and the entire screen, which causes colored spots in the camera area.

This forces brands to work on solutions to there is a balance between the two, which allows for great photos, without having to touch the screen, just the opposite. At present it is not known when these solutions will arrive, which causes a significant delay in their actual application on phones. There are also products like Redmi for this question, at least for now, that a solution might work.

It seems so it's been a few years before it became available the market. The on-screen camera is something most manufacturers want to use, but there are a few issues that they have to overcome first before it can become a thing of the market. What is clear is that it will not be the last to hear about this technology.
