lcd panel grades brands

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.

AGDisplays offers zero pixel inspections in bulk for customers who have a zero-fail pixel standard. Our technicians inspect panels for hot, stuck dead pixel and evaluate LCD quality standards; we then confirm and document our findings for verification purposes.

How does it work? We can receive panels directly from the OEM before they reach you or your customer. You may send LCD panels directly to AGDisplays for inspection. If a panel fails OEM specification grade, we perform an exchange for panels that are standard or above standard for your industry.

There are thousands—if not millions—of pixels in every LCD panel. A panel with 1080x1920 contains 2,073,600 pixels. Business applications that require zero-fail pixel standards can range vastly from medical equipment, to airline entertainment systems and cockpit applications, to indoor and outdoor digital signage.

With so many pixels packed into the incredibly bright and colorful LCD technologies, there are bound to be a few dud pixels. Even turning on a brand-new screen, a user may see a dead spot here or there. When an LCD is manufactured, it may not come off the production line with 100% pixel defect free.

Dead pixel policies vary from manufacturer to manufacturer. Many have created a grading system to categorize the variations in pixel quality from LCD to LCD. Even ISO 13406-2 guidelines specify an acceptable amount of pixels by display category; and each industry has different standards in which pixel defects are acceptable. Many expect LCDs to have absolutely zero dead pixels.

In an LCD screen, resolution is the number of pixels contained in a display monitor. Resolution is represented as a pair of numbers indicating the number of pixels vertically and horizontally, such as 800x600. Image sharpness is determined by the resolution as well as the size of the display. A smaller monitor with a resolution of 800x600 will have a better resolution than a larger monitor with the same 800x600 resolution.

•What is Our Grade A LCD Monitor:: LCD Monitor is in Good physical and working condition, LCD screen is bright and nice and there is no bruise, blemish or Dead Pixels/Bright Pixels(dead or defective pixels.), since the LCD is used so casing does have minor scratch or scuffs comes from normal use.

•What is Our Grade B LCD Monitor:LCD Monitor has gone through our extensive Test program and is in working condition, but has some issue preventing us from selling them as our normal "Grade A" monitors. LCD Monitor maybe has some bruise, blemish ,Dead Pixels/Bright Pixels(dead or defective pixels.),scratch or scuffs on the screen or case.

An LCD video wall is a large visualization surface that is built from multiple LCD displays (also known as ‘tiles’). These individual displays are designed specifically for use in these applications, and differ highly from normal television sets. The biggest differences are the bezel width, the mounting system, and the reliability. Normal television sets are designed to play a few hours per day, these specific panels are expected to play much more. Often even 24/7. And because the environments in which these video walls are deployed are sometimes critical, the uptime needs to be as high as possible.

Especially important for video walls, is a perfect calibration. This is not only restricted to a single panel. More critical, is that the color and brightness settings of the complete wall match. This means that the values of all panels need to be synchronized with the surrounding displays. If not, even the slightest deviation in color or brightness will make the wall seem out of balance.

High brightness: The light output of LCD video walls is generally quite high. Especially compared to LED-lit rear-projection cubes, LCD scores better. This allows the use in most lighting conditions - even in daylight.

Low real estate needs: Rear-projection cubes are quite deep, and (unless front access is available) need a rear maintenance area. As such, they need a lot of real estate space. LCD video walls only take the place on the wall of the panel depth and the wall mounting. This is usually less than 20 cm / 7.9”.
