After determining a good buy LCD TV or plasma television and screen size , then choose which one to change the brand's consumers want TV should bother . So in the end is to buy domestic brands more affordable LCD TVs , LCD TVs or buy joint brand more protection?
Of course, the main selling point of these brands among various flat-panel TV or different , and some advocacy functions , and some main appearance, in fact, most can not be ignored or quality , after all, the most basic and most important function of the TV or take look . Quality , but off function also appears to have no other meaning . First, determine whether the quality 1080P Full HD screen , and second, whether there is full HD video processing chip, especially to enhance the circuit for LCD TV picture , best before buying consumers through a network or other information to find out.
One of the most popular feature is network television , first-line domestic brands have the appropriate product launch, but differ on the functional details in 2009 , and a joint follow-up product is less.
In fact, from the entire flat-panel TV market, domestic brands and foreign brands are very close in many ways , such as flat-panel TVs on their overall R & D structure that is synchronized ; using the Tsingtek Character LCD
Modules screen is now domestic brands and foreign brands are almost the same. Of course , some of them in the design, chip technology , there are many differences in their service areas . The main selling point of the various flat-panel TVs differ
If the current domestic and foreign brands a detailed comparison, most foreign brands as international brands have a higher visibility among Chinese consumers ; In design terms , compared to domestic brands and foreign brands, with respect to weak some, but the past two years , many domestic manufacturers , such as in the design aspects of the rapid development. For specific product performance and functionality , the domestic brands and foreign brands also continued to narrow the gap , such as contrast , brightness, response time and other key parameters of many composite indicator of domestic brands is even higher than the foreign brands.
When purchasing products , Tsingtek Serial Lcd
Display Module we also choose what aftermarket . In this regard the domestic brand marketing network and after-sales service network is very robust , they are more perfect after-sales service policy, and also offers a range of branded service projects, in terms of the consumer is also very practical, and this is no one foreign brands can not do , a good reputation and customer satisfaction services are very crucial factor.

How much is appropriate screen election
For nearly two years, with flat-panel TV prices continue to drop , more and more people will buy the target focused on large flat-screen TVs body. But for an optional flat-panel televisions, not blindly size bigger the better, but the right to select the appropriate viewing distance size is the most important . Many , especially for small living ,Tsingtek TFT LCD
Module it is not suitable to buy 46 inches above products , while 40 -inch large-size flat-panel TV can be better achieved less than the effect .
For flat-panel TV purchase size problem , this topic also gives some advice to define the International Radio Consultative Committee (CCIR) is : When viewing distance is three times the height of the screen , high-definition television system display should be equal to or a person close to normal vision , as in the original spot to watch the demo scene or when feeling. In addition, some TV manufacturers have released a number of flat-panel TV viewing distance and screen size to match , for the majority of consumers to buy large flat-screen TVs provide a reference .
Matching principle states that under the same effective angle from the best high-definition picture perception needs 16:9 widescreen, large-size flat-panel TV to achieve the best display effect. Households watching television at a distance of 1.7 m , 2.0 m , 2.4 m , 2.5 m , 2.7 m , 3.0 m , 3.3 m , the 26 inch, 32 inch , 37 inch, 40 inch, 42 inch , 47 inch, 52 inch LCD TVs are able to maximize the effect of high-definition display , giving an immersive experience ; while in the distance under the 17-inch ,Tsingtek 16x4 lcd 21 inch, 25 inch, 28 inch, 29 inch, 34 inch, 43 -inch CRT TV is enough to play their best to achieve the display.
CRT and flat-panel TVs have such a big reason for the difference is that ordinary CRT is designed to show the current analog television system and preparation of , at best, only reached half of its clarity of high -definition TV resolution , in addition it uses a 4 : 3 aspect ratio , these factors leading to the selection criteria of high -definition LCD TV with ordinary CRT TVs differ .

LCD projection technology
LCD (LiquidCrystalDisplay) projection imaging modality for the transmission , the imaging device is a liquid crystal panel , is a passive projection. It uses external sources ( metal halide or UHP lamp ) , so long as the lamp power can be improved to enhance the brightness. It uses LCD projection technology is relatively mature , with good color reproduction , brightness and contrast are better than CRT rear projection. With the continuous development of technology, the lamp life currently plaguing the industry issues will also be a better solution . Currently Tsingtek Character LCD
Module projection did not become mainstream in its main reasons for the high cost . Also LCD rear projection, limited to works on its reasons , its warm-up and cooling after shutdown takes time , you can not do that with the open with CRT rear projection off .
LCD projector LCD panels in accordance with the number of slices into three-piece and monolithic . Currently, three-piece projector Tsingtek 5.7 TFT display module panels are the main types of projectors , the schematic diagram below:
Three -LCD panel of the projector optical system principle is light emitted by the source is formed R, G, B three beams by the beam splitter , respectively, is transmitted through the R, G, B three-color liquid crystal panel ; the control signal source through the A / D after conversion modulation, to the liquid crystal panel , the liquid crystal cell by controlling the opening and closing to control the R, G, B three-color light -off path , and three colored light path through the aggregate , the color combiner prisms together , the final after the projection lens , forming a color image on the screen .

led routine maintenance
LCD monitor relationships with our users most closely , good sanitation work is also very necessary . In fact, the LCD display is also particularly vulnerable to significant dirty, white appearance is really nice, but pay attention to maintenance , it will soon become yellowish ; piano paint really performance, but with one week off , the shell is certainly full of fingerprints ; even the plain black matte material , some time down on the screen is certainly a piece of dust . Many users know to regularly clean the LED display , but you know how to properly clean the Tsingtek lcd module it?
We want to consider purchasing a priority compared to the excellent quality cleaning kit , the cost of cleaning solution generally include the electrolyte , high purity distilled water , antistatic fluid, etc. , can effectively clean the dust on the screen , finger prints and other dirty mark, you can buy some well-known brand products. And good cleaning cloth is also very particular about , it must be ultra- fine fiber -based products , high-end glasses generally send glasses can also be used to make cloth cleaning cloth .
Some people believe that water can be, but also will not damage the LCD screen. However, the relatively poor cleaning effect of water , and clean the dust will be attached over again . Of course , if you want to save money , it will be with water , and better than those of unknown origin cleaning solution to be good. Also note that the point is , do not spray water on the screen , but you want a little cleaning solution is sprayed onto the cleaning cloth , then wipe gently along the same direction , but before cleaning , you need to put the power cord pull out.
For most Tsingtek 122x32 lcd backlit display , they are the most vulnerable place is the screen , the screen is generally less hardness in 3H ( pencil hardness ) , usually do not pay attention to other devices can easily be "friendly fire " when used, and once the screen by loss means that this LED displays basic scrapped.

IPS hard screen advantage
Large viewing angle for the whole family to share
Traditional soft -screen LCD TV , when viewed from the side , color drift phenomenon will occur , resulting in blurred pictures . Because IPS hard screen has a unique molecular structure level conversion , so can reach 178 degrees vertical and horizontal viewing angle , color performance is not compromised at any angle , almost reached the limits of LCD technology , basically eliminating the visual "dead ." Meanwhile, the phenomenon did not appear like a soft color drift screen , can be seen clearly from the side of the screen. It is understood that the opening of the Olympic Games in Beijing Metro Line 5 , the use of almost all IPS hard screen LCD TV technology .
Color accuracy restore the true picture
As the world leader in LCD technology field , LGDisplay IPS hard screen technology was unanimously favored professionals on the world 's top LCD display, such as EIZO, NEC, APPLE and so on professional display products , exclusively uses IPS hard LCD panel screen technology to meet the design, printing, aerospace and other industries demanding professionals of color .
Design and printing of color is the most demanding industries, the reduction in saturation and color accuracy are demanding . IPS hard screen display technology is currently the most accurate color reproduction technology with very high contrast , black level is more clear, therefore , professionals in the field of design through the use of generally considered IPS hard screen LCD monitor designed to effectively reduce the and finally produced the error between samples . In addition , depending on the degree of scientific examination of modern medicine increasingly high ,5.7 TFT display module IPS hard screen ideal black contrast effect is to help improve the speed and accuracy of diagnosis. Relatively speaking , IPS panel, better consistency , more detail for ultra- fine grayscale display requirements .
Size advantage
On the size of the LCD screen , compared with the traditional soft- hard screen LCD screen is also obvious advantages. For example, the mainstream market , and 40 -inch 42-inch panels , with a hard screen technology than the 42 -inch LCD TV screen technology on soft 40-inch area of more than 67.58 square inches , this is not just literally two inches difference, but more of a full laptop . On the 42 -inch display screen digital TV more complete picture , so that consumers can enjoy a larger picture of events . The 40 -inch screen is slightly inferior , but also a small part of the corner does not show up on the restore screen has IPS hard screen to identify missing
( 1 ) touch color lcd display module screen , without waterlines phenomenon, can be recognized as IPS hard screen ; If there waterlines phenomenon, can be recognized as a soft screen .
( 2 ) to use a magnifying glass, liquid crystal molecular shape comparison chart , scaly direction toward the left is full pixel IPS hard screen .

Plasma TVs achieve the 3D effect of the three technical advantages
Plasma TVs name is PlasmaDisplayPanel, Chinese called plasma TV, which is injected into the gas mixture between two thin glass plates , and the use of light-emitting phosphor imaging voltage is applied to the device . Compared with the CRT tube display with high resolution, large screen , slim rich colors , bright features. Compared with TFT LCD
Module, with high brightness, high contrast, viewing angle, bright colors and rich interface features .
Plasma TV Plasma (PDP) as compared with the conventional CRT TV TV TV PDP most prominent feature is the " large and thin," but also in other characteristics : thin and light structure ; Wide ; against electromagnetic interference ; flat image without distortion ; no convergence and focus problems.
The disadvantage ; Because the use of R, G, B phosphor from the light on, he addressed a fixed pixel display images , time display of high brightness, high contrast of still images , it is easy to produce residual images , and even burns screen phenomenon . So when you watch TV , without affecting the normal viewing conditions , to minimize the TV brightness and contrast. Plasma (PDP) and compare LCD liquid crystal (LCD, LED) televisions (Lcd display module) televisions , plasma and LCD televisions are contemporary mainstream technology , represent two different directions. Two flat-panel TVs have their advantages and disadvantages , plasma TV with a flicker-free images , thin , lightweight , colorful , lifelike images and other characteristics, and relatively easy in terms of large-scale screen . The disadvantage is the relative LED TV is slightly heavier.
LCD TV also has a flicker-free images , thin , light weight and other characteristics, and the LCD screen is widely used in PC area, but higher in terms of the big screen of LCD technology behind plasma , big screen LED TVs cost , easy to watch affected by the viewing angle .
