One, led splicing screen and lcd splicing screen appearance difference
lcd splicing screen looks like a home TV, only considering that it is mainly splicing use, so it's a very narrow bezel, only a few millimeters, at present, it is mainly in inches for the size of the unit of measure, the current mainstream on the market are 46 inches, 49 inches, 55 inches, 65 inches and so on.Led color screen is By a small lamp bead composed of different sizes of the unit plate, according to the different lamp spacing of its unit plate is also different, and then by a number of boards spliced into a large screen. Can be visualized from the gap can be distinguished.
Two, led splicing screen and lcd splicing screen display effect difference
lcd splicing screen is the use of led back-illumination, so it is the whole of the luminescence is more uniform, the brightness and contrast is more balanced, the most critical is that it can realize the single-screen 1920 * 1080 resolution display, and the highest can also realize 4K and point to point display. So we see lcd splicing screen will be more clear, the screen will not be harsh.
And led full-color display all the lamp beads are exposed outside, and maintain a high brightness display, and because its resolution is determined by the size and spacing of the lamp beads, so it is in the overall aspect of the resolution is lower than the lcd splicing screen. And the led screen will be more harsh if you watch for a long time, this is because it is too high brightness reason.
From the brightness point of view, the two splicing technology do not have to worry about not enough. Instead, the small pitch LED electronic screen known for high brightness faces the problem of over-brightness. Contrast indicators above, small pitch LED is the best, but from the demand side, the contrast of the two technologies are more than the real display needs and the human eye's resolution limit.
Three, led splicing screen and lcd splicing screen use different environments
lcd splicing screen can only be used indoors, because it consists of many internal electronic parts, with all the electronic products, it does not have the characteristics of waterproof, so it is suitable for indoor use in a dry environment. The led color screen that can be used indoors, can also be installed in the outdoors, which is also its special structure decided to add waterproof measures can be used in outdoor environments.
In the resolution (PPI) indicators, although the small spacing LED has been in the breakthrough, but still not able to compete with the LCD splicing screen, currently in the 55-inch unit to achieve 2K popularity of only the LCD screen, the future has the hope and the ability to popularize the 4K even more only LCD screen. For small pitch LED electronic screen, higher pixel density means that the stability of the design of the difficulty of geometric growth, the pixel pitch down 50%, the backplane density will have to enhance the 4 times, which is why the small pitch LED has broken through the bottleneck of the 1.0, 0.8 and 0.6, but the real mass of only 3.0/2.5 products such as this is the root of the reason.
Fourth, led splicing screen and lcd splicing screen hardware defects are different
Product characteristics, hardware differences make them also have a difference, such as refresh frequency, which is effective in suppressing the screen screen flicker sense of the key indicators. LED screen refresh frequency is generally very high, most of the LCD is 60-120Hz level, have exceeded the human eye's discernment limit. lcd Splicing screen not only in the display has certain advantages, and its stability is excellent, rarely after-sales situation, at the same time, its panel is processed through the industrial grade, so it can withstand the whole day continuous power on work, which is why it began to enter the security monitoring display field is the main reason.
And in terms of unit thickness, liquid crystal has an inherent advantage, and has been constantly optimizing it has been progress; small pitch LED display has been achieved although the super-boom, but the future of the progress of the space will not be too big. Optical pollution and visual comfort, LCD mainly refers to glare and high-frequency blue light, small pitch LED is too bright and high-frequency blue light problem.
In the consumables and display core life indicators, mainly refers to the LED display beads and backplane, LCD screen and light source, LCD life advantage in this regard is the most clear, the overall can reach 100,000 hours, LED screen beads individual differences and the stability of the backplane problem determines the life of such products between the individual splicing body life difference is more significant, individual units may soon need to be replaced.
Fifth, led splicing screen and lcd splicing screen application
Finally, according to the lcd splicing screen splicing seam, its application areas mainly include security monitoring, conference, display, big data, fusion media, advertising and other occasions. Although the resolution of the full-color lcd display is low, the impact will be much smaller if viewed from a distance, and because it is spliced without a gap, it is widely used in advertising, brand release, display advertising and other fields.
There is no absolute who is better, we all have their own advantages and disadvantages, accurately speaking, should be in a certain occasion, who is more suitable. Although it is said to be the same industry, but each has its own advantages and characteristics, only to see whose advantages and characteristics more in line with the needs of users. The demand is the king.
