The pace of the Spring Festival is approaching, and many consumers are beginning to consider buying their favorite flat-screen TVs. Go around the store, and the boom of LED LCD TVs will inevitably ......Different from the previous **rampant,LED LCD TV has a price and no market,On the eve of the National Day,In LG、Skyworth and other brands of LED LCD TVs have been listed in batches,The actual sales of LED LCD TVs have been pulled a lot。 Many consumers who are holding on to buy have begun to release their enthusiasm for consumption.
So,In the face of this new force in LCD TV,How can consumers pick a truly outstanding LED LCD TV in all aspects。 Expert reminder: look at the panel first, then compare the backlight.
Buying LED LCD TV Cheats 1: The panel is the key At the beginning of the launch of LED LCD TV, a brand directly named it "LEDTV", which was questioned by industry insiders and consumers. LCD TVs are televisions that use liquid crystal display (LCD) technology on the display.
So the real sense of the LED TV,It should be a TV with a LED panel。 The so-called "LED TV" has nothing to do with the LED image display, but the LED light source is added to the backlight of the LCD TV. Therefore, this kind of TV should be called "LED backlit LCD TV".
The controversy over the naming actually reflects the key and importance of the panel from another aspect. Because the panel is the real decisive factor in the image quality, the backlight is really just an improvement. Therefore, for LCD TVs,The panel has always been the core of LCD,The quality of the panel is the key to determining the quality of the picture display effect,It also determines the quality of LCD60%.
And when it comes to the panel, the advantages of IPS hard screen have to be mentioned. Compared with VA soft screen,IPS hard screen due to the creative arrangement of liquid crystal molecules horizontally,Improve the stability of the LCD screen,With stable picture,Fast response time,Higher dynamic image quality,Wide viewing angle,Small color distortion,In LCD TV,With IPS hard screen panel products with the best picture quality,Widely welcomed by machine manufacturers and consumers。 In the LED backlight LCD TV, the model with an IPS hard screen panel is also the best picture quality.
It is precisely because of this that IPS hard-screen LCD TVs have been in short supply. Relevant experts reminded that the way to judge whether it is a hard screen is very simple, just touch the TV screen, because the IPS hard screen will not produce water ripples when touched like a soft screen. Although the panel technology has not changed, the change in the backlight still brings about an improvement in image quality.
According to authoritative tests,LEDLCD TV has been greatly improved in picture performance、Environmental protection and energy saving、Ultra-thin appearance、Color performance, etc.,And direct-down LED LCD TV,These characteristics are vividly exerted。

In 1888, liquid crystal materials were discovered;
1888 1968 was a period of research on the properties and applications of liquid crystal materials.
In 1968, the United States was the first to make LCD products;
In 1973, Sharp made TN-LCD;
1973 1985 was the period when TN LCD was widely used.
In 1984, STN-LCD and TFT-LCD were invented.
1985 1993 was the period of promotion and application of STN LCD.
1993 2000 is the period of great development of TFT LCD, during this period the performance of TFT LCD has been comparable to CRT.
The development of LCD has greatly expanded the application range of displays, making it possible for individuals to use mobile handheld displays, so after 2000, LCD and CRT will enter the era of competing for the mainstream market of displays.
Color low-power reflective LCD technology.
Low-temperature polysilicon (PSI) LCD mass production technology.
Development of large-size, wide-view, high-resolution color TFT LCDs. Before 1993, the main products produced were sub-inches, 640 480 pixels; 1993 In 1997, the main production was 10 inches, 13 inches, 1024 768 pixel products; From 1997 to 1999, it mainly produced 15-inch 18-inch, 1024 768 and above pixel products; After 1999, it began to produce 20-inch and 30-inch products.
After 1998, he began to vigorously develop high-resolution, large-screen LCD projection TVs.
In 2008, people paid more attention to the beauty and thickness of LCD TVs, and the thinnest TV under 26 inches can now be 22 mm.
The white screen of the TV may be caused by the screen cable falling off; The fuse of the circuit board is blown and the picture tube of the TV is fused, the components in the TV are aging, the positive and negative voltage of the liquid crystal display is insufficient, and the reception signal of the TV is abnormal. >>>More
