1. The clarity of the LCD screen is fixed
LCD screens are widely used in TVs, monitors, splicing screens, and some small-sized smart display devices. The reason is that it uses LED backlighting, the entire screen is clearer and the light is more uniform. There are mainly two kinds of resolutions. For the LCD splicing screen and computer monitor we usually use, the resolution of an LCD screen is basically 1920*1080 or 3840*2160, which is what we often call 2K, which belongs to HD and UHD display. It can meet most of the current playback needs, because the conventional film source is magnetic at most, which can fully meet the normal display needs.
For example, if we have a 4K movie that needs to be displayed, then the resolution of the TV can be satisfied, and it can display its proper video effect as it is. If there is a higher resolution display requirement, you can use an LCD splicing screen. After splicing, the resolution can be superimposed, which can realize the point-to-point display needs and achieve a maximum 16K display.
2. The clarity of the LED screen is determined by the dot pitch
Before understanding the clarity of the LED screen, we must first know how the clarity of the LED screen is determined. The LED screen is spliced together by small modules, and a module is distributed with many small lamp beads, lamps and lamps. The distance between them and the number of lamp beads is also its resolution. The smaller the dot pitch, the more lamp beads, the higher the resolution and the better the natural clarity.
For example, a P3 LED module, its size is 304*152mm, then when calculating its resolution, its length and width can be divided by the dot spacing, that is, 304 divided by 3, 152 divided by 3, and a The resolution of the P3 LED module is about 101*51. In order to achieve the resolution of 1920*1080, 19*21 modules need to be spliced together, so that a P3 LED screen needs to display a complete display. 1920*1080 image, then the whole screen should be 5776*3192mm
We can see that using the P3 LED screen to display a 2x image requires the screen to be more than five meters wide. It can be seen that its resolution is much lower than that of the LCD screen, because the ordinary LCD screen is only one meter wide. Of course, using some small-pitch LED screens can greatly reduce the size of the LED screen. For example, we use 0.9, which is a relatively mature small-pitch LED screen, but it is still not as high as the LCD screen in terms of clarity.
Therefore, from the comparison point of view, the LCD screen is clearer than the LED screen, so if we are using some indoor large-screen display systems for close-up viewing, it is better to use the LCD screen, such as the exhibition halls of some companies. , big data display platform, media advertisement and conference display.
