LED displays and LCD splicing screens account for nearly 80% of the large-screen splicing display market. However, LEDs use lamp bead packaging technology, while LCD splicing screens use LCD technology, so their display effects are very different, with obvious advantages and disadvantages. Which is better for users? It also depends on our display purpose, such as for video surveillance or small meeting rooms. At this time, LCD splicing screen is more suitable. If used for outdoor advertising screens, LED screens are more suitable.
First, the advantages of LED display
- No seams
The unit of the LED display screen is a unit board, and the unit board is distributed with lamp beads of different sizes, different spacings and different numbers. The color of the chip is controlled by the chip, and the color of the chip is controlled by the chip. If you want to assemble a big screen, you need to splice multiple unit boards together, and it has no splicing obstacles. There is no seamless connection between the boards, and there is no border like an LCD splicing screen, so there is no trouble of splicing.
- Waterproof and sunscreen
The structure of the LED makes the LED display waterproof and sunscreen, so we can see that some outdoor displays are LED.
- High brightness adjustable
The brightness of the LED display can be adjusted freely, and under different lighting conditions, such as outdoor facing the sun and facing away from the sun, the brightness is completely different. In order for the screen to be clearly visible, it is necessary to adjust its brightness.
two,Disadvantages of LED display
The resolution of the LED display is much lower than that of the LCD splicing screen. Even the resolution of small-pitch products cannot be compared with that of LCD splicing screens. The direct consequence is that LEDs will appear mosaic when displaying images. When looking up, the text will be composed of small squares, and the picture clarity will be poor.
- Low Contrast
Low contrast will lead to insufficient brightness and layers of the picture, so the picture is not good, which is not as good as the LCD splicing screen.
- High after-sales service rate
The lamp beads on the LED display screen will fall off, die and other phenomena, and they are more frequent, which will increase the after-sales rate and cost.
- Auxiliary cooling is required
If installed outdoors, sometimes the temperature of the LED display will be higher. In order to achieve rapid cooling, air conditioning will be installed, which is equivalent to an additional cost.
Third, the advantages of LCD splicing screen
- High resolution
One of the advantages of LCD splicing screen is high resolution, the resolution of each screen is 1920*1080, the resolution after splicing can be superimposed, so it can achieve full HD display, such as playing 4K video, so we see the clarity of LCD splicing screen degree is very high.
- Appropriate brightness
The brightness of the LCD splicing screen is the same as that of the TV, which is suitable for long-term viewing without glare. If you use the LED screen indoors, you will feel high brightness and hurt your eyes.
- High contrast
The contrast between light and dark is strong, and the picture is rich and delicate.
- Stable and durable, low after-sale rate
The LCD screen has a low usage rate in the later maintenance, which can greatly reduce the later use cost of the LCD screen.
- Powerful display
The LCD splicing screen can use a single screen as a unit to achieve internal segmented display, and can also display multiple computer signals on different screens, and the display screen has powerful functions. If there are 5 computers in a conference room that need to be displayed on the screen at the same time, you can assign a computer signal to each LCD splicing screen and switch a matrix.
Fourth, the shortcomings of LCD splicing screen
- There are seams
The traditional LCD splicing screen is limited by the LCD panel itself, and there will be a border around the screen, so that after splicing, a splicing gap with a width of several millimeters is formed, which looks like a black edge. If it is displayed in full screen, it will affect the viewer’s experience. However, our company has launched a seamless LCD splicing screen product, which indirectly realizes the elimination of splicing and achieves the effect of splicing.
- Can only be used indoors
The LCD splicing screen is mainly composed of LCD panels with electronic components inside, which are not waterproof and can only be used in a dry indoor environment.
If we are faced with a choice, our advice is that if we are using a lecture hall or press conference for remote viewing outside or indoors, we can mostly show a big picture. At this time, we can consider using LED display.
