lcd module Introduction and principles
LCD module simple point that is screen and backlight components. LCD TV display unit is a liquid crystal module, its status is equivalent to the CRT tube. The other part includes a power supply circuit, a signal processing circuit, etc., and of course the housing or something. The main screen is divided into modules and backlight components. The two parts are assembled together, but when the work is independent of (Character LCD
Modules , the circuit is not relevant). Principle of LCD backlight unit is uniform surface emitted light, the light transmitted through the LCD screen of our eyes. The screen in pixels is the role of these light processing to display an image. When the liquid crystal panel manufacturing selected control IC, filters and accessories directed film, the contrast with the panel about the relative CRT monitors easily reach 500: 1 contrast ratio even higher in terms. Only high-end LCD monitors in order to achieve this such an extent. LCD is a TFT Lcd
Modules that is between the solid and liquid itself is not light, and requires the use of an additional light source to the job. Therefore, the relationship between the number of lamp LCD monitor brightness. The first LCD monitor only down two lamp, to the present, universal minimum is four lights, high-end six lights. Four lamp design placed into three forms: one is the four sides each have a lamp, but the drawback is in the middle there will be shadows, the solution is on the way from the lower level of the four lamps arranged, the last one is placed in the form of a "U" is in fact a disguised produced two lights two lamps.

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 .

Adjust the brightness allows a more realistic color representation
Brightness is the brightness of the LCD TV is the brightness of the screen, it is also an important parameter index LCD TVs. Reasonable brightness can make our eyes more comfortable, but it will not affect the color performance of the screen. In general, high brightness hand easily cause visual fatigue, but also to reduce the black and white contrast , the impact of color gamut and grayscale performance. Because the brightness of the LCD TV is achieved by adjusting the backlight . The higher the backlight brightness , LCD TV itself more easily to dilute colors , picture whiten.
Now available in many of the hundreds of known brightness of the LCD TV 1000 lumens, 2000 lumens , is not good , you know the brightness of traditional CRT TVs generally about 300-600 lumens, has a very good performance . The actual use situation, adjust the brightness of LCD TVs 50% is more appropriate . If you feel too bright , some may be further reduced in accordance with the actual situation. If the brightness of more than 70 %,I2C Lcd Display it may affect the performance of the color screen .
Small with disabilities : The current general brightness of the LCD TV backlight control by using CCFL (cold cathode fluorescent lamp ) backlight technology, the performance of the NTSC color gamut for only about 75% , while the use of LED backlight LCD TV can show more wide color gamut can be more than 100% NTSC color gamut .
Contrast adjustment presented with more picture detail
Contrast is the same point on the screen when the brightest ( white ) when the ratio of the darkest (black ) of brightness , higher contrast ratio means that the screen can show more detail , can show more color scale, which makes colors more gorgeous. Unfortunately , the current market value of most LCD TVs contrast marked , are called dynamic contrast ratio, basically not much real meaning.
That is why when we adjust the LCD TV QVGA lcd, nor can it adjust the contrast is too high , otherwise it could lead to a situation picture whitening ; If too low , it may be an excellent screen color is very light situations. In general, about 50% of the contrast value is more appropriate . In addition, if a non- special needs , the best dynamic contrast feature LCD TV off.

Large screen manufacturers brand development is the mainstream
At present , the domestic Ultra Narrow LCD splicing system the main technology manufacturers are concentrated in the hands of foreign countries , resulting in the domestic market is flooded with assembly machines , product homogeneity serious, in this case , how to grasp their brand positioning in order to achieve brand value and have their own advantages to develop marketing channels is the current mainstream big screen manufacturers to develop the direction of development .
Homogeneity in all competitive industry are likely to occur , the lcd module splicing homogeneity within the industry is mainly homogenous liquid crystal panel , but the panel is not equivalent to the homogeneity of the homogeneity of splicing systems , in fact, because the level of technology, manufacturing quality control, differences in levels of production , LCD splicing market products in quality , there are very different , with the upper panel displays superior resources and have long experience in the production of the vendor's products quality and more reliable.
DID Technology technicians Tangxiang En said: "The 46 -inch LCD panel production line investment is huge, requires huge capital investment, research and development costs greater worldwide manufacturers do not have much , but this market in China has been investing overdose ; domestic the strength of the enterprises do not need self-built LCD panel production line, you can deepen their own image processor chip R & D , and Apple phones similar , even if the screen , and many other hardware products are not their own production, but can also make high-quality products . "
Development of market channels to be combined with manufacturers to their own characteristics , the ultimate aim is to achieve win-win complementary vendors and channels together for the vast number of projects and provide customers with better products, more convenient access and more attentive service .
Currently TFT Lcd Modules splicing industry infighting makes good and bad quality of products on the market , many small and medium enterprises in the service can not keep up , the lack of systematic application development and implementation of the solution is poor , allowing customers to choose products face greater risk ; another vicious price competition makes the whole industry is in profit or even negative interest is not conducive to the LCD splicing overall industry 's healthy development. But the fierce market competition will make those who pay attention to brand , technology, products and channels, enterprises gradually grow , liquid crystal display market in the future , those who have a complete industrial chain advantage , continuous technological innovation, overall service ability, the ability to customize client solutions strong manufacturers will be the ultimate winner.
Brand positioning and value realization requires a long time to see results , you can use market segmentation approach to the delineation of the scope of their markets and increase their brand added value. In fact, the large-screen display system now has presented brand development trends, industry threshold is gradually improving , large-screen enterprise wants to become bigger and stronger , and in the fierce competition, brand development is the only one can go road.

lcd back lighting method
Electroluminescent (EL) back light thin lightweight body provides uniform light. Its low power consumption, the required operating voltage of 80 ~ 100Vac, provides the operating voltage of the inverter can be converted to 5/12/24Vdc input AC output.
As the EL back light of limited life (at 50% brightness average life under the conditions of 3000 to 5000 hours in the life of a higher brightness level will be greatly shortened), so the ideal inverter for EL back light allows the output voltage and frequency with increasing aging of the EL lamp, and thus the rear extension of the EL display of the effective light source life.
EL back light for like a watch, a digital desktop clock and monochrome PDA, etc. require extremely faint illumination so dimly lit or dark conditions using a small reflective LCD applications, it is more suitable. However, low efficiency, low brightness, and its use in short-life such as a laptop computer and a desktop flat panel monitors such as requirements of large transmissive graphic lcd modules backlighting applications.
LED back light EL longer than the life (over 5000 hours), and a DC voltage, typically used in small monochrome display, such as front cellular phone, remote control, microwave, stereo audio equipment. However, the brightness is not enough to provide for large transflective display with back light.
Small cold cathode fluorescent lamp (CCFL) are provided for large OLED Display Module desired brightness and life (as well as lighting control capacity), which it is still the most common method of backlighting causes. However, the heat accumulation is a matter of concern.
Rear light assembly from the past with relatively moderate power levels driven one or two CCFL increased to 30W or 60W of power for up to 12 (or 16) Root lamps. As in a relatively small space with so much power used, so heat accumulation makes the back of the monitor light source assembly of all the elements are in most of the early application of the LCD module not occur on the force level. Moreover, electrical efficiency and lighting control capabilities are also close to the limit.

Response time of the LCD market competition
LCD monitor for now ordinary consumers already not a strange term, and with the growing market demand, consumer demand for LCD monitors is unprecedented high level of concern. It is with a "no radiation, no flicker, low power consumption," the environmental concept of a display device is now mainstream of development, especially 17 inches is exceptionally compelling products, which were a very important reason is that the price record lows.
Response time for LCD important technical indicators
As the price of approachable, LCD monitors are now as many consumers choose one of the objects, and as LCD monitors become mainstream, consumers have a single price of this small space to jump out, eyes locked on the LCD important technical aspects, the most prominent point is the response time of liquid crystal displays, it also became the focus of manufacturers and media publicity.
From the current LCD technology development perspective, shorten the reaction time, improve reaction speed, become the dominant direction of the liquid crystal development. The original has been plagued by fatal LCD response time is also a qualitative leap in nearly two years, a longer response time LCD display on the display, when the object moves quickly appear "smear" phenomenon, which makes Some gamers extremely uncomfortable. To overcome this limitation, now on the market can continue to see the latest and fastest LCD market, a single crystal from the response time of the important details of the performance point of view, the manufacturers for its improvement is obvious from the original 60m s, 50m s, 25m s times to the present 12m s, 8m s has become the market mainstream, the pursuit of a shorter response time vendors and users have always been trying to pursue the limit.
Gray response time to become a new selling point products
Because people's constant pursuit of LCD screen, from last year, a new concept --- "gray response time" frequently mentioned by the maker, it makes use of LCD response time, such as meter race records, time and again to be refreshed, to create a new history, and the original concept of mini lcd module response time to give a new definition.
Original response time, generally refers to a black screen from the white screen sum of the time required for conversion, in a real application environment, pure black and white screen and rare, actual use More to the transition between different gray levels, which is most of the time because the LCD display screen to be displayed in color, and the color picture is a combination of the three primary colors RGB, the three colors according to the different scale display color. RGB color sub-pixels according to the different colors, there will be changes in different shades, so that the change process is called "gray." The above mentioned maker gray response time, which is GTG (GreyToGrey), refers to the process of transformation between different gray levels mean, this parameter can be more truly reflect the performance of a single monitor, it subverts traditional response time is calculated on the improvement of smear achieve a qualitative leap in LCD technology to become a new bright spot. However, it is noted that, due to changing the speed between different gray are not equal, so gray response time is only a statistical average, is not a uniform time.
Gray response time to fully reflect the multi-color LCD to switch the authenticity of the energy use in the technical advantages, grayscale Low Temperature Displayproducts for the control of smear more in place, the human eye can see the screen smear phenomenon minimize the situation to ensure that the motion picture clarity and stability. We have reason to believe that, by virtue of the above-mentioned technical advantages, it is bound to gradually replace the traditional black and white switching response time LCD products.

Plastic antistatic agent profile
Plastics are widely used in modern society, polymer composite materials, it has a high surface resistivity (25 ℃, RH60%, resistance 1017Ω). Therefore, when the friction charged, the static electricity easily removed and retained by the conductive surface of the plastic. Since the presence of static electricity, not only affects the appearance of plastic products (cleaning, etc.), but the main thing is the impact of the manufacture and use of plastics. To this end, plastic anti-static agent, its role is to reduce the plastic surface and the surface resistivity polymer charge density, so as to achieve the purpose of electrostatic hazards released. In general, the resistance of the plastic is very large, it is charged by friction or contact with, easy to trigger a variety of electrostatic effects, such as discharge, shock, dust and damage absorption appearance, IC short circuit. In order to avoid this effect are generally used antistatic agent.
Typically, in order to prevent generation of static electricity plastics, the following methods are mostly used,Character LCD Display one normal humidity environment to maintain and use, suitable for addition to the motor; the second is applied to the surface of plastic low-molecular type antistatic agent; Third, the use of carbon , filtered and the permanent conductive antistatic agent; Fourth, in the conductive polymer material to improve its molecular structure. In addition to using the plastic antistatic agents, but also used in the fiber, paper, paints, inks, petroleum products, etc. These products are often static adhesion of stains situation.
From the comparison of various anti-static technology point of view, in addition to static physical means, material characteristics are not changed, but the equipment expensive, can only be applied in some shapes; for product surface treatment method is simple, but the lack of durability; conductive paint coating, can be used in complex shapes, 240x64 lcd module and is applicable to a wide range of materials, equipment, costs less, but the price is high, the risk of peeling, and uniform coated film is difficult; metallised there are no partial peeling, but Application materials are limited and costly equipment, resulting in environmental pollution problems.
Within the method of adding an antistatic agent, a surfactant (low molecular weight antistatic agent), cheap, easy to operate, easy to change but the material surface characteristics, friction, easily washed off, and is not colored; add permanent antistatic agent (hydrophilic polymer), electrical conductivity, good stability, but the price is high, the added amount is greater, and will be subject to the physical properties of plastics.

Blue LED
A long period of time are unable to provide blue light emitting of the Lcd display modules . Design engineers can only use the existing colors: red, green and yellow. Early "blue" devices are not really blue LED, but surrounded by a blue incandescent light scattering material.
A few years ago, the use of pure silicon carbide (SiC) material developed the first "true blue" LED, but their light efficiency is very low. Next-generation devices using gallium nitride-based material, its luminous efficiency can reach several times the initial product. Current manufacturing blue LED epitaxial material is indium gallium nitride (InGaN). Emission wavelength range of 450nm to 470nm, indium gallium nitride GaN LED can produce five times the lcd module light intensity.
