TN Encyclopedia wide viewing angle

In 2009 TN panel LCD rapid development, but because of too rapid development and pursuit of the shortcomings exposed by also attracted the attention of consumers . TN panel LCD color gamut is limited, narrow viewing angle , while the backlight is not ideal , and many other issues experiencing severe test of the market and consumers . Coupled with the expansion of product lines too fast , and manufacturers in order to seize the time to market similar products and innovative enough to ignore the phenomenon , so many consumers lose confidence in such products .

Wide viewing angle is due to lcd module viewing angle is small, a large angle to the side when viewing the screen will be pale, contrast and color performance is also poor , so the plant was developed by a panel of a technology. Wide viewing angle technology department only related to the display 's viewing angle , but also affect the monitor's response time and brightness and other parameters. So adding wide viewing angle panel display has also been awarded the title of high-end products .

LCD panel changes concern most consumers , this change also allow consumers to experience high-end technology to the LCD display strong incoming civilian attitudes . But with the growing number of types of LCD panels , each vendor near perfect qualifier for consumers in the purchase of intangible opportunities, what is the difference of these LCD panels ,OLED Module you know how much more they ? Today we have for you to spread knowledge about the type of panel .

Uncover the history of the three major fallacy LCD TV

About 10 years ago , LCD TVs began to emerge, smaller size and larger display area means that the traditional CRT LCD TVs will be replaced , then the terminal market has long been predicted candidates , LCD TV to replace the CRT tube TVs even faster exceed industry expectations, followed by the traditional CCFL LCD TV backlighting is also the transition to LED backlighting , followed by another 3D TV and the emergence of smart TVs , LCD TVs can be said that the entire development process is very fast .

● One fallacy : LCD TVs more energy efficient compared to CRT TV

See this title , it is inevitable that some readers feel weird, do not worry, then I will explain in detail . Recalling the beginning of LCD TVs coming time, that is the early development of LCD TV , LCD TV manufacturers to strongly assert more power than television CRT tube , which is an instant success and even irresponsible.

LCD technology is mainly used in LCD monitors and LCD TVs , and in the early development of LCD technology , LCD compared to CRT monitors indeed the same size to be more energy efficient , while compared to the same size LCD TV CRT TV but did not dominant, there are even more costly electricity is suspect. Also LCD technology , why does this happen ?

● The second fallacy : Dynamic Contrast quality is more

LCD technology development at the beginning of the consumer from the parameters of the liquid crystal panel LCD products will be able to read the approximate performance of a panel attributes (TN, MVA, PVA, IPS , etc. ) , brightness , response time , contrast , viewing angle etc., and even experienced users can identify a little MVP, PVA, IPS LCD panel strengths and weaknesses, then LCD is really a very simple areas of the world . Until the emergence of dynamic contrast , the original field of liquid crystal pure world has changed ...... become dirty .

Injustice has a head debt of the Lord , the dynamic contrast ratio is brought into the field of liquid crystal Korean manufacturers , OLED Module was the best LCD panel contrast ratio of 1000:1 , and dynamic contrast appears, even a TN panel can also easily over 1000 : 1 dynamic contrast ratio from the outset quite converge to 1500:1 start, followed by endless 2000:1,3000:1,5000:1,8000:1,10000:1,50000:1,100000:1 All LCD manufacturers are exaggerated than the data , until the ultimate consumer unbearable, lcd module manufacturers seems to have realized the seriousness of the situation , the dynamic contrast ratio only gradually fade from view .

● The third fallacy : the new LED backlight technology is stronger than traditional CCFL backlight picture

A naughty little boy to grow into mature man , take some time and process . For a new technology , in fact, is the same reason , back in 2009 or so , the new LED backlight technology just around the corner , much to replace the traditional CCFL backlight technology momentum , TV LED TV manufacturers in order to squeeze more profits, blind LED backlight technology for landscaping , most can not tolerate is : LED backlight technology quality performance better than traditional CCFL backlight .

What makes a good flat-panel TVs

With the continuous development of the TV , it looks and has has been changed . TV from a big box transformed into a chunky tall, thin guy now . Not only look endearing , and its connotation ( application functions ) also improved, to the user who brought many surprises .
When consumers buy TV time , the choice of brand name products better.
Housing size :graphic lcd display module Optional TV when we can housing size , population size , economic conditions and other factors to select the TV . Determines the size of the TV housing sizes , such as 16 to 20 square meters room , choose 32 inches to 39 -inch TV will be able to achieve the best visual effects, 20 to 30 square meters room , choose 39 inches to 47 inches TV on the line .
The ideal distance to watch a TV 3 times the TV screen , 42-inch television can be seen that the optimum viewing distance of 2 to 2.5 m; 50-inch television optimum viewing distance of 2.3 to 3 m; 60 inches TV best viewing distance of 2.7 to 3.6 m .
Service: pick service , mainly to see the LCD screen warranty. Under normal circumstances, manufacturers are providing the machine ? Some parts warranty does not contain or alternatively a short time, other parts of the three-year free warranty service. So , to remind consumers Repairs must ask more questions , oh.
Resolution: For LCD TV , the resolution is an important parameter . LCD TV resolution (resolution) is about the panel displays an important indicator of image formats .serial display modules Typically we are referring to the physical resolution refers to the resolution of the panel , the screen displays the number of points , the horizontal and vertical pixel values ​​, this value determines the resolution of the LCD screen , it is also very important.
