Why do laptops have worse viewing angles than desktop screens?

The material of the screen is different The material of the desktop monitor may be IPS This type of screen has the highest viewing angle The maximum seems to be 178°, basically it looks like there is no dead angle.

And most of the screens of this book are made of TFT material, only a few high-end machines are made of IPS screens, and the viewing angle of TFT is generally only 130°. So that's how the difference came about.

The display screen of the laptop has advantages and disadvantages compared with the desktop,Its advantages are that it can protect eyesight,Easy to carry, etc.,The so-called angle affects the picture,If you buy a super screen notebook, there will be no such problem at all,Of course, it's much more expensive!

The disadvantage is that it is expensive and easy to damage, and the life of the LCD screen is relatively short, which is much different from that of a desktop. Except for ultra-brilliant screen notebooks, the color of ordinary LCD screen screens is much worse than that of desktop ones.

Regarding the viewing angle, it has nothing to do with the laptop or the LCD screen.

The viewing angle of a notebook refers to the angle at which the screen of the notebook can be rotated.

However, the LCD is divided into LCD screen and LED screen, the viewing angle of the LED screen is better, the viewing angle of the LCD will be relatively small, and the best angle of the LCD is the vertical line of sight, that is, the eyes and the screen are in a 90-degree vertical state!

Viewing angle refers to the angle from which the user can clearly see everything on the screen from different directions. Generally, the viewing angle is 120 degrees, and the viewing angle of most notebook screens is not much different. Users can observe the viewing angle of the notebook from different angles, generally from the four directions of up, down, left and right**, so as to judge the size of the screen viewing angle.

Let's take a closer look at the viewing angle of the screen: Since the light source that provides the LCD display display has a certain directionality when it is refracted and reflected, color distortion occurs beyond this range**. The size of the viewing angle determines the size of the user's viewing range and the best viewing angle.

If it's too small, the user will deviate slightly from the front of the screen, and the picture will be discolored. The average user can use the viewing angle of 120 degrees as the selection criterion. At present, the viewing angle of the best LCD display on the market is symmetrical, but the upper and lower angles are not necessarily symmetrical, and the upper and lower angles are often smaller than the left and right angles.

When we say that the viewing angle is 80 degrees to the left and right, it means that the screen image can still be clearly seen when standing at a position of 80 degrees from the normal of the screen (i.e., the imaginary line in the middle of the display). The larger the viewing angle, the better the angle, and the more applicable the LCD display. Since everyone's vision is different, we use the contrast ratio, and the greater the contrast measured at the maximum viewing angle, the better.

At present, most products on the market have an angle of view of more than 120 degrees, and some products have reached more than 170 degrees. It should be noted that the nominal value of viewing angle is also different under different measurement methods, and since display manufacturers usually do not specify specific measurement methods, in general, viewing angle is only a reference value. Although the viewing angle of the laptop screen is not a big issue, it is still worth noting when buying a laptop.

Due to the different LCD screens used in various brands of notebooks, the viewing angle is also uneven, so it is best for you to test it yourself when you buy, and show the display effect at different angles, so that you can have a more comfortable viewing effect in the future use process.

There are about 90 degrees to 120 degrees, but the LCD angle is basically more than 140 degrees.

This is generally related to the angle of sight, and it is OK to look at it comfortably. It's usually 90-100 degrees.

Since the light from the LCD is emitted forward at a near-vertical angle through the liquid crystal, when we look at the screen from other angles, we will not see it as clearly as we can see the CRT monitor, but will see obvious color distortion. This is due to the size of the viewing angle. Specifically, viewing angles are divided into horizontal viewing angles and vertical viewing angles.

When choosing an LCD monitor, you should try to choose a product with a large viewing angle. At present, the LCD display is basically at an angle of more than 140 degrees, which can meet the needs of ordinary users. Regardless of the value of the viewing angle, whether it is convenient for your own use is the key, and it is best to choose according to your daily usage habits.
