Graphic lcd modules course consumers should be cautious to use some non-ammonia

In fact, both the liquid crystal display maintenance, generally you can use microfiber cloth dampened with water to clean the glasses can ; But if you can not effectively achieve the clean effect, then consider buying a dedicated screen currently marketed cleaning kit ; course consumers TFT Display Module should be cautious to use some non-ammonia, alcohol , and inorganic salts ingredients cleaning fluid to clean up , so the screen is the correct maintenance of the road .

Maintenance points to note :

1 Whenever possible, use microfiber glasses cloth.

(2) If there is dust on the optical Character LCD Display mirror , first pat shake the dust leakage ; re- wiping action , so that it can be avoided in friction due to dust particles by wiping cloth swab , while the mirror caused by scratching.

Graphic lcd modules even achieve prevention and early diagnosis of the disease

Its base is golden silk, attached to the skin by electrostatic after this electronic skin through real-time monitoring pulse, heart rate , body temperature, vibration, and other muscle groups physiological indicators of human health , human health data changes and make timely feedback , even achieve prevention and early diagnosis of the disease.
Because the electronic skin is extremely sensitive with conductive nanomaterials , even if it is a bit of quivering muscles electrical changes , it can be accurately sensed.
This is a University of Texas research team at Seoul National University in Korea jointly developed electronic skin . It is only 4 cm long, 2 cm wide, 0.003 cm thick , stick in your hand graphic lcd display module looks a bit like a tattoo.
And electronic skin developed by Chinese scientists , as it built a variety of human data monitoring sensor with high sensitivity , but it also equipped with a memory that can store and transmit the work to complete the monitoring data .
More cattle is that this electronic skin also designed a pharmaceutical interface for real-time data and Serial display modules according to human health, the drug is released directly into the human body through the electronic skin more quickly and efficiently complete the course of treatment .
However , whether domestic or foreign electronic skin , they also need the help of an external power supply and data transmission devices to work properly, form and function from the wearable device market there is a certain distance.

Lyotropic liquid lcd module displays crystal to generate example is soapy water

 found the dish (discotic) liquid crystal , is a nematic or column line system high symmetry intact molecule composed of overlapping . In addition to pattern classification , the LCD because the condition ( condition ) generated is divided into different thermotropic liquid crystal (thermotropic LC) and lyotropic liquid crystal (lypotropic LC), respectively, by heating , adding a solvent to form a liquid crystal phase liquid crystalline phase heat generated two kinds of situations .
Lyotropic liquid crystal to generate example is soapy water . At high concentrations , the soap molecules lcd module are smectic interlayer water molecules . Lower concentrations , the combination is different.
In fact, a substance may have a variety of liquid crystal phase. It was also found that the two kinds of liquid crystal mixture is heated , then cooled to give an isotropic liquid , can be observed sequence of a nematic , smectic liquid crystal . This phase china lcd module change material , known and reproducible crystal (recentrant LC). The molecular structure .
Vanderbilt magic liquid crystal phase is stable between molecules . Because of the high density molecular assembly , repulsion anisotropy greater impact, but the attraction is to maintain a high density , so that the liquid crystalline state to achieve collective strength, repulsion and attraction of mutual checks and balances is very important. Another example is when molecules have polar groups, dipole-dipole interaction has become an important attraction.

How to choose flat-panel TVs peripheral functions

With the rapid development of today's flat-panel TVs , watching TV is no longer the sole function of the TV. After entering the liquid crystal , plasma era, additional features of the TV even more. In addition to watching TV, DVD, play games, video, recording, Tsingtek OLED Display Module browsing with photos , Internet ...... so a dizzying array of new features coming out on the flat-panel TV .

See this, and some people may get confused by the same author . We buy televisions, mainly to watch TV and DVD, or play the next game consoles connected . Those with cameras , recording, processing photos and browse features flat-screen TVs , for us, in the end it is more practical or flashy it? Not blindly require multiple attachments

Faced with this problem , I believe that the current flat-panel TV has its distinctive features highlights , but for different additional functions corresponding to different consumer groups. For example, now many of my friends like to download movies / dramas on from the network , and then connect the TV to be viewed through a computer , and with access to the Internet network TV appearance , no longer need so much trouble, the TV directly connected to the network , directly enjoy the movie , do not need so much trouble , it is more practical for those who like to watch movies / dramas elderly .

For example, an office worker also football fans , to work on time every day , often miss some exciting football tournament program , which can record function can be a good solution to this problem. But for one do not like the football program , but just watch some TV programs , see the news network of friends, this feature is a little redundant, Tsingtek custom lcd display somewhat superfluous .

Of course , we can not blindly require multiple attachments , the blind pursuit of additional features can pay more money, and get what they need, we want to choose according to their needs .

Buy LCD or Plasma ?

For a flat-panel TV without regular contact with ordinary consumers, prior to purchase flat-panel TV will have a question: " is to buy an LCD TV or Plasma TV is good and what difference does it both ? ? "

From now on, LCD TVs and plasma TVs are the mainstay products in the field of flat-panel TVs , both have their own strengths , competing with each other , have their own space for development , especially with the development of flat panel technology , plasma Resolution reach high standards, bigger and expensive LCD TV , motion picture tailing serious problems have been overcome , the difference is narrowing.

A technical comparison

Of course, from a technical point of view , there are still some differences between the two . Such as high-definition LCD TV image , body thinner, more stylish and beautiful ; Tsingtek 128x64 lcd display plasma in brightness, color , layering , and so has certain advantages. Here we were to look at the technical characteristics of both understanding :

LCD technology principle: a liquid crystal projection display (Liquid Crystal Display, LCD) LCD is a rearward light-emitting fluorescent tubes , then through a set of lenses and turbot backlight module , the light is uniformly transmitted to the front , in accordance with the received video signal , the liquid crystal liquid crystal molecules within the pixel layer of the glass should be arranged relative to which the light is deflected or barrier to be determined .

Plasma Technical principle: the light-emitting principle of plasma display (Plasma Display Panel) PDP is to inject an inert gas or mercury gas in the glass tube , using a voltage mode , the gas generating a plasma effect , emit ultraviolet light, the individual RGB three excitation type fluorescent body have different primary colors visible by using the length of time to generate the excitation of different brightness.

2 , the dynamic contrast resolution

During the discussion , such as whether to buy an LCD TV or plasma TV, a dynamic definition of a contrast is also very important items. General speaking , the dynamic definition refers to the moving image during playback screen resolution , sharpness, dynamic screen presence embodied in the "tail " , the impact of presence and overlapping . This depends mainly on the TV itself, the response rate, response speed should be noted that this concept is generally concerned for LCD TVs .

LCD TVs currently on the market , the response time is generally 4-8 ms encountered rapid screen ( fast motion such as soccer , racing, etc. ) , it will produce smearing . However, with the advent of 100Hz/120Hz even 200Hz/240Hz multiplier technology, smearing improved, but limited by the working principle , trailing difficult to eradicate the problem . For plasma TV , the response speed of up to 2-3 microseconds Tsingtek low temperature 240x128 lcd, 1-3 microseconds with traditional CRT flat , beyond the scope of the human eye can recognize completely negligible .

In LCD and plasma performance synchronous upgrade stage, we still have to choose according to their needs , after all, is the best fit . If you are a hardcore amateur sporting events , or to vote for a big plate plasma care of yourself aesthetic movement concept, but also pay attention to their energy problems , after all, is the long-term benefits of energy-saving , energy-saving recommendations must purchase a plasma . If the pursuit of fashion and aesthetic quality , it can be carefully selected in numerous boutique in LCD .

DLP rear projection technology

DLP (DigitalLightProcessing) refers to the digital light processing technology, which we first video signals through digital processing, then projected , the projection display good quality. Transmissive Tsingtek graphic lcd display module projection and imaging different , DLP is a reflective way . Its kernel is TI ( Texas Instruments ) has developed a digital micromirror device -DMD (DigitalMicromirrorDevice), DMD is the final part of the visual display of digital information , which is the standard CMOS semiconductor process , coupled with a tunable reflection formed on the surface of the rotating mechanism device . Typically , about 1.3 million DMD chip installed hinged micromirrors , a micro-mirror corresponds to one pixel. The principle is to use a rear projection DLP integrator (Integrator) homogenizing the light , the three primary colors through a color wheel (ColorWheel), separating the light into R, G, B three- color light source is inclined to the mirror , the reflected light to the lens , equivalent to the optical switch "ON " state. When the mirror tilt to the light source in the opposite direction , the reflected light is less than the lens , equivalent to the optical switch "off " state. The gray level of each second optical switches , switching frequency ratio determined . Therefore, the use of synchronous signal method for processing digital signals lens rotation , continuous light into gray , with R, G, B three colors and the color shown, the final projection imaging , we can produce high -quality, high-ash grade images.

Currently there are DLP projector DMD chip machine, two-piece and three DMD DMD machine machine . According to their different characteristics , with different applications. Which is mainly used in portable monolithic projection products , two-piece used in large tiled display wall and three type is mainly used in high brightness projector. DLP rear projection TVs generally have 4-5 times more common definition TV , and has the advantages of high brightness, high contrast ratio , 1000:1 contrast ratio can be achieved . In addition , the use of digital technology, improve the image gradation , image noise disappears , the picture quality is more stable. However Tsingtek Serial Lcd Display Module, TI is currently the only manufacturer worldwide DMD chip supply caused by the projector's weak areas , inadequate supply of core components , low yield, expensive, and therefore to some extent limit the development of this product , Besides the long run DLP projection technology is restricted in ultra-high resolution ( 2000 lines or more ) terms .

Cleaning and maintenance of the four criteria for flat-panel TVs

Spring and more sand , I remember a few days ago on the gale blew times , because I forgot to close the window before leaving the house made ​​of dust everywhere , even to buy a new LCD TV also cast a very thick layer of ash . Although grazed changed again after the clean, dust can be life if long-term erosion of the TV will be shortened. We must also have the same experience and the author , then how should we care and maintenance of their own LCD TV in more sand in the spring it? Here I gave you a few suggestions .
It is important to properly clean

I once for the easy way with a paper towel or a rag dipped in water to clean the dust on the LCD screen , I believe many of my friends also to do so . In fact , this method is very undesirable. Because both the paper towel or rag Although seemingly weak , but they are for the screen is still too rough and the water cleaning effect is not very good , if the water is too large screen, easy to damp short-circuit .
The correct way is to choose a professional cleaning cloth and cleaning fluid in the cleaning , should not spray cleaning solution directly onto the screen , first sprayed onto the cleaning cloth in the same direction regularly wipe gently. And do not use excessive force when wiping to avoid damaging the screen. This dust more like spring season, we want to ensure that at least one week to clean them once .

Select the correct placement

Dust is to make television shortened a major factor , then in addition to that we also need to maintain the cleanliness of how to do ? Here will have a problem when it comes to television placement . First choice is not to be placed upwind , because the wind would carry some dust falls on television , is likely to cause an increase in its internal dust is not conducive to heat, shortened life expectancy. The second is the spring easily from static electricity , a home theater with a friend on the particular attention to the subwoofer do not put together with the LCD TV , as the subwoofer will produce a strong magnetic field magnetization LCD TV components , it will not work long magnetization work .
Avoid TV continuous work

We often talk about work and rest , in fact, the Tsingtek lcd modules TV is the same. If continuous working temperature will cause the TV itself , heat will accumulating in LCD TVs inside the fuselage , it was not enough as much of a threat to electronic components, but the LCD panel is likely to burn , thus forming a large area of ​​dead pixels the .
In addition , there are now a lot of TV pause function , we have to be careful not to let the TV fixed on a screen for too long, longer if time had to be shut down. Because this will damage the screen a .

Avoid hard object impact

LCD screens are fragile , easily damaged if you do not pay attention , once the screen repair damage means a series of trouble . To avoid such problems occur , we should avoid strong shock and vibration , the home of friends with children should pay special attention to this point .
In addition, some friends accustomed to pointing at the screen , and even some people feel ripples generated by the LCD screen is very interesting, so intentionally or unintentionally, to press the Tsingtek color lcd display module screen. It does not matter for CRT TV , LCD TV but may cause fatal damage.

Summary:

In summary, we have time to get their own LCD TVs use longer , at least pay attention to the points above problems. This will not only prolong its life but also eliminates the need for maintenance, trouble, effort and money , why not.
