When choosing an LED display, it is more important to clarify our own use requirements, and then communicate with professionals according to their needs, and find a practical solution to this problem, which will be more important than looking at more parameters and technical terms. solve our problems. Of course, we can also see from what angle other users view the product. However, if you have your own needs, it is even more important to have a solid understanding of them.
For example: installation environment, required size, approximate budget, etc. Shenzhen Huarong Electronic Technology Co., Ltd. Class A users explain the LCD screen.
The XXX LCD screen is relatively good in terms of viewing angle, color, and animation display quality. Most of the big screens in the circle around our city use this company. Led display is a display method by controlling semiconductor light-emitting diodes.
It roughly consists of many LEDs, usually red, that turn the lights on and off to display characters. A display screen for displaying various information such as text, graphics, images, animations, references, video and video signals. Advantages: The cost of raw materials is the most advantageous, the production and processing technology is simple, and the quality is stable.
Disadvantages: poor color consistency, serious mosaic phenomenon, and poor display effect. Group b users explain the LCD screen. The LCD screen you mentioned should refer to the LCD screen, and you should choose the LED screen.
Choose LEDs: Compared with LCDs, LED displays have advantages in terms of brightness, power consumption, viewing angle, and refresh rate. Navigation for this page has been disabled. Using LED technology, it is possible to create displays that are thinner, brighter and clearer than LCDs.
1. The power consumption ratio of light-emitting diodes and liquid crystal displays is about 1:10, and light-emitting diodes are more energy-efficient. 2. LED has a higher refresh rate and better performance in video. 3. LED provides 160° wide viewing angle, can display various text, numbers, color images, animation information, and can play color video signals such as TV, video, VCD, DVD, etc.
4. The single-element reaction speed of the LED display is 1000 times that of the LCD screen. It can be taken care of under strong light and can adapt to the low temperature of minus 40 degrees. Simply put, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, and LED is a display screen composed of light-emitting diodes.
The LED displays currently on the market are not real LED displays, but LED-backlit LCDs, and the LCD panel is still a traditional LCD display. In a sense, this is somewhat fraudulent! South Korea's Samsung was once judged by the British Advertising Association to violate the country's advertising law because its "LEDTV" LCD TV was suspected of misleading consumers. For LCD, the most critical is the type of LCD panel and backlight.
The LCD panels on the market generally use TFT panels, and the same is true. The only difference between LED and LCD is the type of backlight: LED backlight and CCFL backlight (that is, fluorescent lamps), which are diodes and cold cathode tubes, respectively. The difference between LED display and LCD display: LED backlight: power saving (compared to CCFL power saving 30%~50%), high price, high brightness and saturation.
CCFL backlight: Compared with LED backlight, it consumes less power (it still saves a lot of power than CRT), and it is cheaper. Screen difference: LED backlight has brighter colors and higher saturation (the natural light sources of CCFL and LED are different). How to distinguish: LED backlight will emphasize LEDTV, while CCFLCDTV will not be emphasized.
LED advantages: 1. Self-illumination, saving power in dark places and power consumption in bright places. The black areas simply do not emit light. 2 The color is more vivid than LCD.
3 itself is a light source, so there is basically no problem that the TV is getting darker and darker after using it for a long time. The quality is also better. 4 It is not a pure liquid crystal, it is a light-emitting diode, so there will be no faults such as screen lines.
5 In the face of strong light (such as sunlight), it can still display most of the images, and you can’t see clearly with ordinary LCDs. Disadvantages: 1. To put it bluntly, it is a reduced version of a large billboard on the road. Because each A pixel is a light source. So your eyes are not very comfortable after looking at it for a long time. 2 You know, the technology is advanced, and the price is relatively high... LCD Advantages 1 Traditional LCD, skilled in technology.
I don’t know how many generations of products there are, and there are very few design defects. 2 The former has bright colors, while the LCD has softer colors. Because the LCD is a liquid crystal panel + backlight 3 Price advantages Disadvantages 1 The old fluorescent tube backlight LCD will have the disadvantage of dimming the screen light after a long time. Now basically use LED backlight.
This kind of problem is almost a lot less 2-screen lines and dead pixels, which are common problems of a small number of LCD products. If there are too many bumps and bumps, it will happen if you are unlucky. .
