How to Fix a Cracked Huawei Mate LCD

Having a cracked LCD screen or an unresponsive touch panel can be really frustrating. Fortunately, this can be fixed easily at home by following the steps below.

This replacement kit includes LCD display screen and Touch digitizer, but does not include Front Housing Frame. High quality tools and adhesive will be included in this kit.


The Mate 9’s IPS Huawei Mate LCD LCD panel has a very wide color gamut. This is a benefit for some applications, but it can also lead to excessive saturation and muddy, overcooked colors.

It’s easy to correct for this with proper calibration, something Huawei has struggled with in the past. This time around, the display performs well with a well-balanced RGB profile. The Mate 9 is also bright enough to avoid noticeable aliasing on curved edges.

Like many of its competitors, the Mate 9 has some issues with off-axis viewing. There’s a white, red-tinted glow that’s clearly visible at angles greater than about 15deg and starts to wash out blacks around 45deg. It’s even more pronounced when viewed through polarized sunglasses. This is a result of stress birefringence in the cover glass, which Huawei says it has fixed with its new version of the phone. It’s a little frustrating, but it’s not a deal breaker. The screen has a Low Blue Light mode that removes the most harmful blue light from the display, and it passes TUV Rheinland’s low blue light certification tests with flying colors.


Huawei, best known for its phones, laptops and tablets, has a small range of monitors under the MateView brand that are aimed at style-conscious creatives who want top notch colour accuracy. They come pre-calibrated to a Delta-E of less than 2 and their IPS panels cover the full sRGB imaging gamut and a respectable percentage of the much wider DCI-P3 video gamut.

This display supports up to 10 bits per color, but by default it runs at 8 bits with only the sRGB mode enabled (other modes cause the display to run in a very dark and unbalanced aqua tint). It does not support HDR, although its high contrast ratio, low black point and sRGB coverage results suggest that you should be able to see huge punch and depth in games.

The default Warm and Cold white point settings are both too far from the D65 target, increasing imbalances between blue and red while reducing green primary slightly to give the screen a minty green tint. Manually calibrating to a custom white point yields better results but still leaves the display lacking compared with competitors.


The display on the Huawei Mate LCD is bright enough to handle most environments with ease. It also supports HDR content, giving it a more realistic and immersive visual experience.

The screen on the Huawei Mate LCD is an IPS-NEO panel manufactured by JDI. It uses a PenTile RGBW matrix that includes an extra white subpixel to increase brightness without increasing power consumption. This allows the screen to reach higher maximum brightness levels than traditional QuadHD LCD screens.

Color accuracy in default mode is decent but not spectacular. Average DE2000 errors are below 3 and only highly saturated colors show significant error. However, a custom calibration with better RGB balance reduces the error component due to hue shift and drops the error significantly.

Unfortunately, this calibration suffers from a strange gamma behaviour. It’s closer to 2.2 than the target and produces a distinctly reddish image. The sRGB/Natural setting fixes this somewhat but still leaves the greens quite bluish. Manual adjustments with the colour wheel are not able to correct this issue. As a result, the display doesn’t meet the high expectations of creatives.

Response Time

Huawei is better known for its phones, tablets and laptops, but it also makes a small range of monitors. Its curved and flat displays are available under the MateView branding. The company offers a wide variety of features, including support for AMD FreeSync and Nvidia G-Sync.

The screen has an impressive maximum brightness of 411cd/m2 and provides a rich, deep colour experience in games. Its sRGB and DCI-P3 coverage results are excellent, too. However, the display doesn’t offer any contrast boosting or smart dimming options which could have made it more useful for gaming and photo editing.

The display has a VA panel, which means its pixel response time isn’t the best. This causes some blurring in fast-moving scenes. The overdrive mode helps to reduce this, but it isn’t ideal. The viewing angles are also a little limited, which makes the display less suitable for professional work. Despite these flaws, the MateView GT is a solid gaming monitor with an attractive design and good motion handling. But it’s expensive, and cheaper rivals offer more features and realistic colours.


The Huawei Mate LCD joins a tiny club of phones that use the company’s own brand of near-bezel-less display design. It’s called FullView, and it propels the Mate into a class of Huawei Mate LCD its own beyond what other manufacturers call QuadHD (2560×1440).

It’s the first phone from Huawei to sport a 1440p-class display. At 5.9 inches, this IPS panel delivers a pixel density of 499 PPI. The panel doesn’t suffer from the backlight bleed and uniformity issues seen on other panels we’ve tested. However, it does exhibit some off-axis viewing problems, such as a noticeable white glow and a rainbow effect that’s most pronounced on a white background. These appear to be caused by stressed birefringence in the cover glass.

The display can reach a very high brightness, up to 730 NIT. This allows the Mate to easily display HDR content, and the screen’s black level is also very good—equal to the Mate 8, LG G5, and slightly better than the HTC 10. The Huawei’s color space coverage is also excellent. It covers the DCI-P3 gamut very well, though it doesn’t quite match the wider Adobe RGB.
