With the increasing attention of flat-panel TV, TV has indeed ushered in a period of upgrading. CRT TVs in stores are gradually being asked out of the counter or the most conspicuous position, and manufacturers have stopped production or reduced production of CRT production lines, which also provides a good development space for the popularization of flat-panel TVs.
Now it is about to enter the sales peak of flat-panel TV in 2009. Color TV manufacturers launched many preferential activities for this period, such as direct drop, gift giving and cash back. The price of flat-panel TVs is not as high as it was two or three years ago. Both small-size and large-size LCD TVs have experienced a great price dive, which is very attractive.
Don't spend less than five thousand. How to choose LCD?
With the further development of promotional activities, I believe many consumers have been paying attention to the market dynamics and want to seize the opportunity to buy their favorite LCD TVs in the near future. However, when attacked by the financial storm, even if we have money, we must save it. This is a netizen running out and asking, "What LCD TV can I buy for 5000 yuan? Can you buy a 42-inch full HD? "
Two years ago, I would definitely recommend a good 32-inch LCD TV to you, but today, there are many options to buy a full HD LCD TV over 40 inches. Below, I would like to recommend some popular LCD TVs below 5,000 yuan to netizens, hoping to help you buy LCD TVs in the near future.

liquid crystal TV
At present, the life span of LCD TVs on the market is marked as 50,000 hours by most brands, while it is marked as 60,000 hours by companies such as Sharp and Samsung. If you use it for 8 hours every day, you can use it for 17 and 20 years respectively. It is the TV set that has been publicly marked for the longest time, so you can use it with confidence.
The service life of TV is generally calculated by its wearing parts, and the service life of LCD is calculated by the service time of its backlight. Judging from the current backlight production technology, as many manufacturers say, it is basically no problem to reach 500 million hours. But the problem is that there are few problems with the backlight of many large-screen TVs, and most of them are problems with software or small parts such as Sony. In other words, under the condition of superior quality of panels, chips, backlights and other large pieces, manufacturers still have the ability to assemble and manufacture.
RoHS does not limit the mercury content of CCFL.
In general, when discussing CCFL as the light source of BLU, environmental protection issues are often discussed, and the mercury content of CCFL is often taken as a topic. After the implementation of RoHS specification in EU, it is believed that the future of CCFL will be cast a shadow. However, if we have a deep understanding of RoHS's specification on mercury, CCFL as LCD backlight is actually included as an exception, that is, RoHS has no specification to limit the mercury content of CCFL, so if RoHS is used to limit the development of CCFL in backlight, it will cause considerable misunderstanding.
LED has good image quality, and color filter-free technology can replace color filter.
With regard to the development of LED application in LCD TV, Sony first announced the installation of LED backlight module on large-size LCD TV in August 2004, and at the FPD International Exhibition held in Yokohama from June 5 to 10, 2004, many manufacturers exhibited LCD TVs with LED backlight module. Such as mitsubishi electric, Fujitsu display technology and NEC liquid crystal technology, as well as Samsung Electronics, Taiwan Province AUO, Chi Mei CMO, Hanyu Color Crystal HSD and Huaying Color Tube are also on display.
The most important purpose of using LED as the backlight of LCD TV is to improve the picture quality, especially the color saturation, which can reach NTSC ratio 100% or more. Among them, Son introduced the LCD TV panel with LED backlight, with special emphasis on bright red and dark green, which can display more realistic colors than the previous methods.
The dynamic adjustment of the picture can not only improve the color saturation, but also dynamically correct the brightness and contrast when displaying different pictures, thus achieving better picture quality.
In addition, the advantage of LED as backlight is that it can replace the use of color filters. Three-color RGB LED adopts color sequence technology, and realizes full-color effect by using the characteristics of human visual persistence, so it can replace color filter. Of course, this must be achieved by the reaction speed of liquid crystal. However, there are still many difficulties that must be overcome to reach this level.
However, LED backlight module is not without its shortcomings, and power consumption is still an important problem that LED backlight module must overcome. With the increasing use of led, in addition to increasing power consumption, it will also lead to the problem of temperature rise. Therefore, cooling system and sensor must be added to solve this problem, so it is thicker than CCFL backlight products in thickness.
HCFL is suitable for LCD TVs over 40 inches.
Regarding the application and development of hot cathode tube in LCD TV backlight module, Philips demonstrated a series of innovative technologies of display technology in SID 2006. One of the technologies is to use HCFL as the backlight of LCD TV, which can reach three times the brightness of traditional LCD, and can also be applied to 66-inch products in size.
Because the brightness of HCFL is higher than CCFL, the number of lamps, the number of inverters and the overall cost can be reduced. However, the diameter of HCFL is relatively large (16 φ). Compared with CCFL (4φ), HCFL is not suitable for emphasizing thin products.
Continuing to improve the cost advantage is still the best choice for CCFL technology.
Although LED and HCFL have their own advantages in technology, there are still some difficulties that must be overcome. The technology of CCFL is constantly improving. In terms of color saturation, CCFL can also achieve 92% high color rendering (HCR). In addition, in terms of brightness improvement, the luminous efficiency of CCFL is also improved by 10%-20%. On the one hand, the improvement of CCFL brightness can reduce the number of lamps and inverters, and reduce the cost and power consumption; Or change the structure of the backlight module and add a diffusion film instead of a high-cost brightness enhancement film (BEF) to reduce the overall cost of the backlight module.
