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 Video Wall Display size, how to choose
In the large-screen display market, the LCD splicing wall display unit by virtue of its slim body of the screen has become a trendsetting new tiled display technology to the LCD screen (LCD) for the splicing unit rapid rise of large-screen system, on the big screen Monitor fields has been widely used, making LCD Video Wall screen gradually attracted much attention. As more and more manufacturers invested in this technology, LCD screen parameters gradually improved, low power consumption, light weight, long life (generally work more than 50,000 hours), with no radiation, the screen brightness uniformity, bright color, etc., and splicing gap is gradually narrowing, gradually reduced from 7.6mm to today's patchwork of bilateral total 5.3mm, prices are declining day by day, the price continues to improve. However, for industrial control, information distribution, video surveillance, entertainment and other fields bars slit LCD Video Wall Display System requirements relative to lower construction costs, it also makes an excellent cost-effective ultra-slim bezel graphic lcd display module Video Wall Display System should be shipped Health. How to choose their own splicing program, but also of great concern to the user, the following example for you to simply explain:
LCD Video Wall Display size selection
5.3mm Ultra Narrow LCD Video Wall Display System is now mainly a 40-inch, 46-inch and 55-inch two specifications. We can according to project requirements, the height and width of the room began to start counting:
For example, a room LCD tiled display wall reserved area is: W 8 .5 m, height 3 .1 m: a first step, with a height of about 1 m minus the bottom support height, 3.1 m-1.1 m = 2.1 m; access down from the display highly selective display size, display size 16:9, 40-inch is generally 910.2mm (W) × 520.8mm (H), 46-inch General 1025.7mm (W) × 579.9mm (H), 55 inch general 1215.3mm (W) × 686.1mm (H).
Then, according to this basic dimensions we calculate the number of layers stacked: 40-inch, 2100 ÷ 520.8 ≈ 4.0, rounded up to 4 layers; 46-inch, 2100 ÷ 579.9 ≈ 3.6, rounded up to three layers; 55-inch, 2100 ÷ 686.1 ≈ 3.0, rounded, the maximum three layers; Next, we want to confirm the display width, 8m net size of the room, the area should be displayed with the middle part, need to subtract both sides of the door or decorative width of at least 3m, that is the reality of the wall width at most 5 .5 m, since you can then calculate the number of monitors arranged, 40-inch, 5500 ÷ 910.2 ≈ 6.0, go to an integer, a maximum of six; 46-inch, 5500 ÷ 1025.7 ≈ 5.4 , rounded up to 5; 55-inch, 5500 ÷ 1215.3 ≈ 4.5, rounded, up to four.
Thus, in theory, splicing out the scale: 40-inch, for up to 4 × 6; 46 inches, the maximum of 3 × 5; 55 inches, a maximum of only reach 2 × 4.
Next, we will choose it. 40 inch to choose the applicable size: 2 × 2,2 × 3,2 × 4,2 × 6,3 × 2,3 × 3,3 × 4,3 × 6,4 × 4,4 × 6; 46 inch can select the following scale: 2 × 2,2 × 3,2 × 4,3 × 2,3 × 3,3 × 4,3 × 5; 55-inch size, then have the following options: 2 × 2,2 × 3,2 × 4,3 × 2,3 × 3,3 × 4.
If it is a large screen video monitor screen display along the entire image or a dispatching room high-resolution image display is recommended to choose the right size, usually, 2 × 2,3 × 3,4 × 4, because it is a 16:9 display screen, so the general principle of choice is the number of columns ≤ rows, or graphic prolate type display.
If only single-screen lcm module, no combination of zoom display purposes, the size of its LCD Video Wall can design according to the maximum size.
This example, a more appropriate choice LCD Video Wall is: 3 × 3,55 inch; 4 × 4,40 inch.
Choose one of the two best principles generally follow the same general area, the large size priority on the grounds that the large size of LCD Video Wall gap small number, the overall style is more concise.
Another option is to, on the same plane, select the number of multi-unit LCD Video Wall displays, video surveillance is generally used in a large number of occasions.
More than just a simple case illustrates, the user can according to their own projects, the number of display units such as integrated aspects of requirements and cost themselves a rough calculation, to choose the most suitable for their own projects LCD Video Wall solutions.

Dehumidifier selection
Currently softgel drying technology are the following: ① tumble drying, ② ③ static crawler drying tray drying. Because the static tray drying technology has to ensure soft capsule surface gloss, no breakage, etc., after four or five years of practical experience relatively static tray drying technology is a trend. Only because the material drying air temperature, humidity, wind speed, its volatilization of the four relevant elements. As the soft capsules own factors, drying temperature is not too high, so in order to improve production efficiency, it had to reduce the air humidity, the drying chamber increases the number of ventilators aspects to find solutions.
To ensure the soft capsule drying chamber temperature, humidity, cleanliness, large number of ventilators, and in accordance with the GMP standard, we must create an artificial environment to meet the requirements of more than four parameters. Current domestic manufacturers of clean air in the drying chamber to ensure temperature, Character LCD Modules cleanliness, a large quantity of air without any problems, difficulty lies in humidity control in this regard. The humidity at 50 to 70%, in the summer air conditioning alone can solve, and soft capsules the best drying humidity is 20 to 30%, generally air-conditioning and compression refrigeration dehumidifier (belonging to the physical and mechanical dehumidification France) simply can not achieve this humidity requirements, to meet this requirement will have to rely on chemical desiccant. Now widely used chemical desiccant is lithium chloride / silica / zeolite dehumidifier. Since lithium chloride is highly corrosive, easily soluble in water, life is short and other shortcomings in foreign countries has been eliminated; while the domestic is now in a variety of reasons, some units are still used. Silicone (SilicaGel) Traditional Chinese word for the silicone, silicon chemical element silicon words of the old name instead of some manufacturers in the alleged sale of its unique, unique silicone. Silica gel desiccant wheel development in the country tends to be slow, has not yet mature, easy to fall off, moisture absorbent fiber paper is coated on the surface of the efficiency of its moisture is less than 20% of mature products internationally.OLED modules Silicone runner mature products imported into the wind parameters in ensuring the premise of 27-30 ℃, the unit volume of 6g/kg dry air dehumidification or so, and made only 2g/kg dry air dehumidification unit below. Molecular sieve desiccant wheel is suitable for air humidity usually requires a very low 1% -10% of occasions, such as cell phone lithium battery manufacturing, specialty plastics industries. Since molecular sieve desiccant wheel regeneration temperature is generally above 160 ℃, high energy consumption, high prices, so pharmaceutical companies in general should not be used.

LED technology advantages and characteristics
According to some data suggest that attention to environmental protection famous European, LED color printer has accounted for the local market share of 30%, and the upward momentum is very fierce. Even in Canada, emphasis on environmental protection and national intelligence applications, LED color printer sales is more than the traditional laser printers. What is the reason for LED popularity so quickly in developed countries in Europe?
This begins with the advantages of OLED Module technology to analyze. First, both in the way the different optical scanning imaging, the LED color printer does not focus the lens from the rotating polygon mirror and other optical components, the advantages of the LED image that the print speed is more efficient, to continuously improve the resolution, and the overall structure of can be done easier.
Secondly, because LED technology resulting dot small, even can be done with image pixel is completely on the other, it is possible to ensure that the actual resolution is consistent with the theoretical resolution, for clear imaging results.
Again, LED imaging system is not as complicated as laser printing system, long lamp life, the use of more reliable and long-term. Fourth, the laser printer laser head is required to reach the photosensitive drum on the optical data for each row scanning and calibration, the calibration level of assurance of the integrity of the rotation speed of the photosensitive drum has certain limitations. LED printing is the use of multi-point light source, without tedious scanning process can be maintained at a high resolution high-speed printing.
Finally, LED color printer energy saving, energy saving, and the work process produces no ozone, odor, LED technology has a well-deserved green energy characteristics can be generated directly in the bright light under low pressure conditions.
With health and environmental protection, high-speed high-quality and smart highlight the advantages of ease of use, custom lcd display technology is increasingly mature, the sudden emergence as a healthy generation of products in Europe, America, Japan and the market share is climbing, is not surprising. And a new term "healthy office", will more and more people's attention.

LCD TV, port knowledge
RS-232
Digital display devices appear RS-232 interface is not as video transmission, but the image adjustment device.
RS232C connector: RS-232C standard (protocol) stands for EIA-RS-232C standards, including EIA (ElectronicIndustryAssociation) on behalf of the American Electronics Industry Association, RS (ecommededstandard) represent recommended standard identification number is 232, which provides cable and mechanical , electrical characteristics, functions and signal transmission process. The maximum transmission rate of 20kbps, cable up to 15 meters. RS232C port is used for computer input control signal.OLED Display
DVI (DVI-I, DVI-D, DVI-A)
In some high-end product specifications, some would otherwise have DVI (DigitalVisualInterface) connector, DVI interface is mainly used in conjunction with a digital display output is connected to a computer graphics display the computer's RGB signals. DVI (DigitalVisualInterface) digital display interface, by September 1998, at the Intel Developer Forum, established by the Digital Display Working Group (DigitalDisplayWorkingGroup referred DDWG), developed by digital display interface standard.
DVI digital signal terminals is better than the standard VGA terminal, the entire contents of the digital interface ensures a digital format for transmission to ensure that the host computer to monitor the integrity of data during transmission (no interference signal into), you can get a clearer image. The main purpose is to allow DVI graphics card via digital picture signals transmitted to the computer screen. Because the previous CRT screen uses an analog signal, so the traditional D-sub15pin computer screen connector is taking the analog signal (composite signal) will display the card of the digital picture signal into an analog signal to the computer screen to go.
Since the digital display (LCD projectors, plasma TV, LCDTV and other digital display products) uses pure digital device, then directly through the digital interface input digital signal will be better of course, but through D-sub15pin becomes somewhat unwise ( first digital signal to an analog signal, and then the analog signals into digital displays, and finally through the digital display to digital signals inside again).160x160 lcd
DVI connector, there are three, namely DVI-Digital (DVI-D), DVI-Analog (DVI-A) with DVI-Integrated (DVI-I), DVI-Digital (DVI-D) only supports digital display devices, DVI -Analog (DVI-A) only supports analog display devices, DVI-Integrated (DVI-I) is to support digital display with analog display. There is such a mix of all, because although DVI digital display device to the standards set, but because through digital transmission does not reduce the effect of the screen, along with in order to consider can be converted into analog signals, so will There are DVI-D, DVI-A DVI-I with three joints, which can be compatible with DVI-I DVI-D devices (including cable), but the DVI-D connector is not able to use the DVI-I cable, so you will see a digital display device is DVI-D connector, cable connector is DVI-I, DVI-I graphics card is the connector. And DVI-I adapter also become D-sub15pin.
HDMI
HDMI interface called the next century international digital TV standard "High-DefinitionMultimediaInterface (HDMI)" is on 9 December 2002 by the HDMIFounders (HDMI Forum) Confirm High-DefenitionMultimediaInterfaceSpecificationVersion1.0 specifications. Pioneere more in October 18, 2003 launched the world's first HDMIDVD player DV-S969AVi-N, HDMI interface, is now almost a fever-level representative.
HDMI-1
HDMIFounders (HDMI Forum) by a Hitachi, Matsushita Electric, RoyalPhilips, SiliconImage, Sony, Thomson, Toshiba and other seven international appliance manufacturers components. HDMI to DVI-based but offers higher bandwidth, maximum bandwidth of 5Gbit/Sec, the highest quality HDTV requires only 2Gbit/Sec, there is a great amount set aside for possible future higher standards of digital signal . And joined the HDCP copy protection mechanisms while increasing the digital audio transmission, thus becoming a dedicated multimedia interface. HDMI support 1920 * 1080P high-definition digital signals, and supports DolbyDigital / DTS digital audio formats.
