lcd panel grades supplier
What is the grading standard of LCD manufacturers? Many people have been vague about the grading of LCD screens, because they have not seen a unified standard. In fact, the grading standards of each manufacturer are different, so I will give you a detailed introduction today. The following LCD manufacturer classification standards.Then the basis of LCD manufacturers to distinguish LCD screen grades:
According to the quality of the LCD panel, it can be divided into three levels: A, B, and C, and the basis for the classification is the number of dead pixels. Of course, some manufacturers will make more detailed distinctions of LCD screen specifications, such as "A+", "A-", "B+", etc.;
We all know that the LCD screen can be subdivided into each sub-pixel, and the sub-pixel can display black and white and three primary colors of red, green and blue. The dead pixel of the LCD screen means that no matter what the image displayed on the LCD screen is, a certain sub-pixel point on the display screen will always display the same color. Dead pixels can be roughly divided into two categories. One is that the sub-pixels are always black no matter how the screen is, which is called a dark point, and the other is that there is always a bright spot on the screen as long as the screen is turned on, which is called a bright spot. Generally speaking, screen dead pixels cannot be repaired, and can only be repaired by replacing the entire screen.
A+ level LCD screen: LCD screen without any dead pixels is called A+ level LCD screen. Through the professional testing software test, there are no bright spots in the power-on state, no dark spots after the display screen, and the display screen is stable and smooth. A+ grade LCD screen is the highest quality LCD screen, suitable for display fields with extremely high display quality requirements, such as LCD monitors, vehicle displays, medical displays, etc.
A-level LCD screen: The total number of dead pixels does not exceed 3, and there can only be one bright spot at most, and the bright spot is not in the central area of the screen, we call it A-class LCD screen. The screen display is still high-quality and smooth, and there is generally no obvious dead pixel feeling during use. General application and LCD TV, home appliance display and other fields.
B-level LCD screen: The total number of dead pixels does not exceed 5, and the bright spot can only have 2 at most, and the bright spot is not in the central area of the screen, which is called a B-level LCD screen. The brightness of the screen is relatively uneven, and the color saturation is relatively insufficient. Most of the cheap LCD monitors use this type of B-level panel, and the cost is relatively economical and cheap.
C-level LCD screen: In addition to the dead pixel of the LCD screen, the screen with line defects is called a C-level LCD screen. A line defect refers to a bright line or a dark line on the screen, which is a display defect formed by a short circuit or an open circuit in the screen. The image color reproduction ability of the c-class LCD screen is poor, and the appearance may even be damaged. It is basically not used in large-screen products. Most of the LCD panels that are cut into small areas are used in small-sized display fields.
The grading of products by LCD panel manufacturers varies from place to place: Korean manufacturers, below 3 are grade A; Japanese manufacturers, below 5 are grade A; Taiwan manufacturers, below 8 are grade A. The nominal grade standard of mainstream liquid crystal display products is: AA grade, and the LCD display without any dead pixels is AA grade; A grade: less than 3 dead pixels, of which no more than one bright spot, and the bright spot is not in the central area of the screen; B Level: 3 dead pixels or less, including no more than two bright spots, and the bright spots are not in the central area of the screen.
A wide variety of grade a lcd panel options are available to you, You can also choose from original manufacturer, odm and agency grade a lcd panel,As well as from tft, ips, and standard.
NDSsi uses only “Grade A” LCD panels in all of its products, while many competitors use “Grade B” panels in order to save cost, and as a result compromise quality. In medical applications, it is important not to compromise the quality of the displayed image since it is often the basis for making clinical decisions. The following tables and images show the differences between “Grade A” and “Grade B” LCD panels in terms of different types of allowable defects.
There are essentially two different types of pixel defects, bright (stuck pixels) and dark (dead pixels).The table and images below show the differences between Grade A and Grade B LCD panels in terms of allowable pixel defects.
Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.
According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?
As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.
For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.
Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.
Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.
With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.

CRTs were the standard of personal home computers and industrial computers for most of the 90’s. The innovative technology that goes into liquid crystal displays (LCDs), outperforms the CRT displays of the past. After the rise of LCD monitors, it is difficult to find the once-standard tube monitors. After the proliferation of LCD screens came true “industrial” grade rugged monitors. AbraxSys industrial monitors meet quality standards far above what a typical screen would ever need to endure. AbraxSys Industrial Grade LCDs will operate much longer than a normal LCD; sometimes over 100,000 hours longer. Industrial monitors with available touch screen configurations are commonly used in industrial markets requiring sunlight readable LCD systems.
It may seem like overkill, but mission critical LCD monitors often need to operate high-dust, high-moisture and below-zero and high-heat temperatures (as low -40C, and heat well over +60C degrees). These rugged displays need to be able to withstand extreme temperatures, dust and debris, as well as being durable to the industrial work environments. Rugged, industrial LCD displays by AbraxSys are very different in quality from the LCD one would normally use in a retail or home environment. AbraxSys Industrial grade displays outperform the quality of regular LCDs and with thin film transistor technology the true industrial LCD monitors now produce a better picture quality along with improved durability.

These 15” models now boast 500 nits of brightness and a high 2500:1 contrast ratio resulting in bright, crystal-clear images. This series of rugged 15.0" monitors is ideal for use in a wide range of industrial, law enforcement, aviation, marine, military, inspection, advertising and transportation applications where 24/7/365 usage is necessary and where temperatures can reach exceptionally high.
AbraxSys recently released a new series of 18.5” industrial LCD monitors. These rugged 18.5” models meet a growing demand for higher performance industrial displays than typically available through other industry suppliers. This newly released series offers such features as 1920 x 1080, true High-Definition 1080P resolution, with choice of 350 nits brightness or 1000 nits Sunlight Readability, extended operational temperature ranges, a multitude selection of inputs including VGA, DVI, S-Video. DisplayPort, HDMI, and Composite, and a host of possible mechanical configuration options and add-on features.
AbraxSys explains the difference between true industrial LCD monitors and the consumer grade monitors which are often repackaged and sold as "industrial grade" to compete with the cheaper LCD manufacturers.
AbraxSys" business model is different. We"ve dedicated our business to engineering high-quality, innovative rugged computer systems and LCD products from top to bottom. AbraxSys carefully considers each component to be utilized within a specific design to ensure our products can withstand your harsh application environments.
