And other dynamic definition plasma and Character LCD Modules

Dynamic definition refers to the dynamic image 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 of the LCD TV because the basic 8 milliseconds or less , which will produce significant smearing . The response speed plasma TVs up to 2-3 microseconds , 1-3 microseconds with traditional CRT flat , beyond the range of the human eye can recognize completely negligible in terms of the dynamic image viewing , plasma become the first choice of consumers flat-screen TVs .

LCD TVs rely on rotating LCD panel in LCD control light by forming an image , rotate LCD (ie pixels from dark to bright or dim the lights ) There is a process that requires a reaction time. Response speed of LCD TVs generally slower , so the performance of the screen when there is a lag dynamic picture of the phenomenon , the so-called liquid crystal "tail " phenomenon. Values ​​greater response speed , screen appears tailing phenomenon more serious image overlay . From the current perspective of the development of Tsingtek Lcd display module technology , the response rate has improved ( horizontal scanning improved vertical still did not improve ) , but by the principle of limited , tailing problem difficult to eradicate.

Currently more fashionable LED LCD TV , has been strengthened in terms of dynamic definition , but because LED LCD TV LCD TV is still using the principles of manufacturing , so in terms of response time is still not completely ignored .

Response speed plasma TVs up to 2-3 microseconds , 1-3 microseconds with traditional CRT flat , beyond the range of the human eye can recognize completely negligible . The latest chip technology can be a dynamic industry's highest resolution 1080 lines .

April 22, 2008 released by the China Video Industry Association, the " dynamic definition plasma digital TV test method " standard, the measuring method: a dynamic display screen on the established dynamic resolution measurement mode to 4.5PPF ( per Course number of pixels ) of the speed , that is about 8.5 seconds per frame to move again , and then determine whether the picture is clearly visible by visual inspection , after the speed change to 5.0PPF, also by visual inspection to determine whether the picture is clearly visible.Tsingtek Character LCD Modules These two dynamic resolution measurement data is averaged. The eye of the flat panel display dynamic performance of real feeling , it can be evaluated by the measurement . 4.5PPF ( picture from left to right lateral movement of about 8.5 seconds ) and 5.0PPF ( picture from left to right lateral movement of about 7.7 seconds ) , more than twice the average number of lines for the TV test .

Select only hard-screen Character LCD Modules TV Buying Guide

The first method , the black screen with a finger touches the screen , if there is no white flashes , it shows a hard screen, and vice versa is soft screen ; second method is in a moving picture , gently tap the LCD panel, if you will severe smearing the screen , the screen proved to be soft , otherwise it is hard screen . For a more professional friends , you can discern from the pixel structure of the LCD panel , it can be said more accurately foolproof. Technology , IPS wide viewing angle is the top technology, which uses a transparent ITO electrode layer , so the higher aperture ratio obtain higher light output , but expressive than soft pure black screen slightly inferior. We know that the LCD pixel which is composed of three primary colors , red, green , and blue. So in LCD TV , a full pixel is composed of red, Character LCD Module green and blue , and we need to see is this three-color pixel is what shape , as shown below , IPS hard screen panel scaly .

Insiders pointed out that , in fact, pick an LCD TV is also very simple, there is no best , only the most suitable, just remember that the main purpose of buying an LCD TV on it. The most important thing is to buy a TV , is always to look at . The survey shows that for consumers who have a flat- screen TV , watching movies, playing digital camera / camcorder content , playing games is to watch television programs in addition to their maximum use of features, Utah to see the movie for the most , reaching 70.6% . Thus , quality , clarity , LCD TV is undoubtedly the key to the selection of key indicators .

Talk function , depending on demand , just enough , but also to avoid unnecessary waste. In addition to the optional graphic lcd display module TV above described these " cheats " , there are other places to consider , such as the various configuration interfaces , etc., is always good LCD panel is important. I do not know read these , if you are into the store to buy time users can be aware of ? !

Response time of liquid crystal TFT Display Module

The so-called reaction time of each pixel LCD display of the input signal reaction speed, ie the pixels from dark to bright or dim light by the time needed ( the principle is the voltage applied to the liquid crystal molecules of the liquid crystal molecules twist and replies ) . Often say 25ms, 16ms is referring to the reaction time, the shorter the time to see if the user does not have a more dynamic picture shadow tail dragging feeling. The reaction time is generally divided into two parts: the rise time (Risetime) and fall time (Falltime), which means that when the sum of both prevail.



CRT monitors , as long as the electron beam hitting phosphor instantly luminous , while the residual glow very short time , so the traditional CRT monitors response time of only 1 ~ 3ms. Therefore, the reaction time in the CRT display is generally not been mentioned. And because the LCD display is the use of liquid crystal molecules twist control light off, while reversing the liquid crystal molecules is a process, so the response time is significantly longer than the liquid crystal display CRT.

25ms to 12ms from the early well-known 16ms then recently appeared , the reaction time is continuously shortened stereotypes are not suitable for liquid crystal displays and entertainment are being huge challenge. You can do a simple conversion : 30 ms = 1/0.030 = 33 per second display screen ; 25 ms = 1/0.025 = 40 per second display screen ;OLED Display 16 ms = 1/0.016 = 63 per display frames ; 12 ms = 1/0.012 = 83 per second display screen . As can be seen the birth of a great progress means 12ms LCD manufacture.

It should be noted that the LCD display has a scanning frequency of restrictions , especially for field frequency ( also known as refresh rate ) , many of which are limited to 75Hz or less , but in terms of general concepts , 75Hz refresh 75 means one second screen looks like this reach 12ms frames per second, corresponding to a 83 .

In fact , we said above, the 12ms response time is the time for switching between black and white screen required , this full white drive voltage required to switch the black screen is relatively high , it is more switching speed fast , up to 12ms; most of the practical applications of the switching gray screen ( LCD and its essence is not completely reversed , incomplete light transmission ) , the required driving voltage is relatively low , the switching speed is relatively slow. So together, in the gray screen refresh rate of 75Hz 12ms has to meet the needs of the Lcd display module .

According to the data showed that:
Reaction time = 30 ms = 1/0.030 per second display screen can display 33 , which is already able to meet the needs of DVD playback ;
Reaction time = 25 ms = 1/0.025 per second monitor can display 40 images, a DVD player and fully meet the needs of the majority of the game ;
While playing the kind of intense action game ( eg QUAKEIII/UT2003/DOMMIII), Speed ​​Pursuit and other games to be achieved if there is no ghosting , the screen displays the desired reaction time at 60 frames per second, the speed should be more than that required = 1 / 60 frames per second display screen capable of displaying = 16.6 ms.

Character LCD Modules screen pixel repair tips

Thank Chen Qu delivery
Now monitors, laptops , tablet PCs , mobile phones and digital cameras and other devices use the color lcd display module screen . Sometimes when we stare at the screen , you will find it at more than a few small points, that is, we often say that the dead pixels. Although fewer dead pixels does not affect the image display , but it looks unsightly always compare , then here we use a few tips to get these small dead pixels.

Causes dead pixels

As the LCD panel production defects , appears on the LCD screen, dead pixels is a very common problem , the LCD screen is composed of a lot of points, each point of the pixel from the RGB color changing color and image formation . But when the pixel problems, so that the color does not change , the formation of dead pixels. Dead pixels are usually divided into several, if it is colored bright spot, it shows that the point of the pixel is just stuck , we can repair this kind of dead pixels . However, if it is black dark point , it means that the point completely broken, even if the restoration is invalid . If you are a new user purchased the product and found more dead pixels , it is best to find a vendor to be exchanged immediately . Note, however, that some manufacturers do not pay for the small amount of dead pixels , for example, some of the liquid crystal display , if the dead pixels or less in three words , I would not swap users .

Marker extrusion

Turn on the computer and the monitor , the screen display is set to a plain black screen ( or other contrasting colors and dead pixel solid ) , so you can make highlights at a glance. Got the pen cap is smooth , it would be the highlight of the cap gently squeeze the front , then you can see the white light, if not, you can slightly increase little harder . About 5 to 10 under after extrusion , the internal Graphic LCD Module screen flow , you can let stuck pixel back to normal, and then let the bright spot disappears.

Gently squeeze with a cap will have some effect dead pixels

Hot towel heating

Use cap squeeze LCD screen may be because the user's force is too large for the screen damage , if you doubt the power , then we can also use relatively safe method to repair a hot towel heating highlights . A towel soaked in hot water , if possible , the use of fire for heating the pot filled with water until it appears at the bottom bubbles. To remove the towel , wear insulated gloves wring it . Will be placed in a plastic bag in a hot towel on the screen there are bright spots , try to ensure that heat is concentrated in bright office , heat about 10 minutes, making the internal LCD display heat flow , so that the bright spot disappears.

How to detect the screen appears a small crack on the panel oled module

Screen panels are very sophisticated things in the manufacture and use of the process if done incorrectly , may cause the screen suffer damage. So Apple is how to detect whether the device's screen was damaged , there were minor cracks and other problems?

Screen panels are very sophisticated things in the manufacture and use of the process if done incorrectly ,mini lcd module may cause the screen suffer damage. So Apple is how to detect whether the device's screen was damaged , there were minor cracks and other problems?

Last week, the U.S. Patent and Trademark Office published the acquired patents, these patents and manufacturing processes, improvements and other related small adjustments . Here we highlight a set of apples used to detect cracks in the screen system patents . Apple's use of external resistors way to detect trace debug screen panels or other devices on the crack pattern .

This system typically includes screens and data processing circuit . Screen with a display panel may be , its periphery is the external resistor tracking facility . Screen intermittent detection circuit can detect external resistor tracking facility fracture, while the data processing circuit can determine the seriousness of the display panel is being damaged. If the display panel is severely damaged, OLED Display the data processing circuit can also be issued a warning to the user's screen destruction issue.

Bar Character LCD Modules TV wall system requirements outlined Analysis

With the flat-panel TV prices fall, more and more bars opted to transform the flat-panel TVs ,4.3 TFT display module combined into a large bar LCD TV wall mosaic in order to achieve modern , dynamic site-specific display. Suitable for bar display splicing system needs to use the increasing bar LCD TV wall system generally consists of large screen display wall , display processor and sound control system.
Because bar special environment , the use of bar TV wall system requires the following characteristics:
( 1 ) LCD Video Wall with a bar and splicing processors are often continuous working time is longer, the work day boot time up to 9 hours or more, and require seven days a week . Therefore requires the use of continuous and stable work can not easily damaged display device and splicing processors. Civilian large-size LCD TVs continuous working time is too long , LCD TV life will be greatly affected , while Beijing Kaibo Tai Qi production of LCD splicing screen or large-sized LCD screen , using industrial-grade display panel, support 7 × 24 hours a day, and brilliant color, high brightness, life is much higher than ordinary household LCD TV.
( 2 ) require low cost , relative to large enterprises and government investment projects , bars for the high prices reflected endurance is very fragile, so the overall LCD splicing wall bar prices are not too expensive. The Beijing Kaibo Tai Qi company has its own manufacturer, also has regional branches, with in addition to the LCD panel ( not grasp the domestic production of LCD splicing screen panel technology ) outside of the whole industry chain downstream . Spread avoid middlemen and high logistics costs, the real benefit of our customers , so splicing LCD screen is very good value for money .
( 3 ) the signal requires a simple , often only need to live video signals from a computer or a dynamic picture playback , but not more complex signal input; also requires simple manipulation of the display processor , the actual application is often no need for control , or mode conversion , requires only a power-up to ;
( 4 ) signal output display requiring a simple and generally only need to assemble into a large screen ,Character LCD Module or the same combination of different splicing , does not require a variety of different signals at the same time display, and fancy window control and other complex functions are not practical ;
( 5 ) Since the liquid crystal display different splicing unit , requiring a splicing processor can support different splicing unit placement , requires splicing processor can support a display unit such as horizontal and vertical angles side , and asked to show the picture can be a complete mosaic ;
( 6 ) some bars on the screen, the entire screen display is less demanding, allow some splicing gap , you can use the LCD wide-brimmed seam stitching . Of course, some of the bar to pursue the kind of full-screen display of the shock effect , you can use our Narrow LCD screen between each patchwork stitching unit is only 6.7 mm , this range comply with the principle of human visual perception , does not affect the viewing.
( 7 ) Certain upscale bars, often also require different mosaic wall bar linkage site , also shows a mosaic wall row / column of the screen, or if you need the system to automatically run a different display modes. Previously to achieve a more dynamic, modern display.

The working principle of the color filter TFT Display Module

TFT LCD panel has been able to produce color changes, mainly from color filters (Color Filter; CF); through the so-called liquid crystal panel driver IC voltage is changed, so that the liquid crystal molecules in a row standing or was reversed shape, forming the gate to select a backlight or light penetration, resulting in the screen, the picture presented at this time just black and white, in addition, the need through the red color filter (R), green (G), blue ( B) layer provides three color hue, form a color display. TFT LCD Misplays
Color filter manufacturing method comprising the dyeing method, a pigment dispersion method, a printing method, a plating method, an inkjet method, etc., in which the pigment dispersion due to the color characteristics, quality, and other aspects * are dominant, thus becoming the color filter rays of the mainstream production methods, the so-called pigment dispersion method color filter manufacturing engineering, including black matrix engineering, RGB works, finishing works, shipping works, first in black matrix project is the first in-alkali borosilicate glass substrate formed by sputtering on chromium / chromium low-reflection layer film, used as a substrate, this low-reflection layer film is called Metal Black, then, then Metal Black side of the positive type photoresist spin coating (Spin Coating), then through the black matrix mask pattern, exposure to UV irradiation and, after developing the photoresist, the Metal Black etched to form a black matrix (BM) pattern, the pattern on a black matrix is ​​formed, then goes RGB engineering, construction is the so-called RGB form the opening R, G, B three-color pattern works first of R colored with Spin coating color resist, a pattern mask by R, and irradiated with ultraviolet light exposure, and then using a base of the Department of the developer to remove the unexposed portion, forming a first color pattern of R, Zaishi above 200 degrees Celsius post-baking (Post Coating), the pattern having a resistance, and then patterned to form the same engineering R G, and B, repeat, the black matrix between the patterns are to be separated, this feature is to increase the display contrast, and to prevent noise light generation, followed in the latter works, is the formation of TFT Array opposite electrode substrate ITO transparent electrode layer, that is, color filters, and finally, shipping and packing engineering is the final inspection. color lcd display module
Color filter process technology critical to note that the RGB color between the segment deviation, segment deviation will affect the LCD performance segment deviation as large displays have faults produce, in addition, RGB works for the high temperature process, so the selection of raw materials shall be resistant to potency does not happen recession Furthermore BM mainly isolated RGB three colors, the key to improve the color contrast and BM generally require low reflection, reflection smaller the better color performance will be better.
