Features And Aesthetics

Front View

As a TV manufacturer, we carefully pick the pretty model for all TVs. The Webos 55-inch TV(MH-55WF01U) is a frameless model. The LCD panel is A-grade so the front view(display) is 100% perfect without any bright defective dots. Meanwhile, the frame is only 6 mm from its edge, providing a good watching experience. Since it is a 55-inch TV and it requires the users to sit at least 3 meters, then the frame can be easily ignored. Meanwhile, we measured the distance between the LCD panel and the frame is 1mm only, which is insanely small. The distance between the display region and the frame is about 6mm only and it is fairly good enough for most of the users. We have tried to eliminate the distance gap to make everything perfect from the front view.

If the TV is powered off, then the TV will become a mirror. Since this 55-inch Webos TV uses a Haze 1% LCD screen(Glass), which is a light-level matte(anti-glare) surface, it can provide the clearest view for a single image in a frame. Some users may prefer the heavy-level matte surface because they hate the “glare” effect when the light in the room or the sunlight from outside is sharing directly towards the screen. A quick graph is provided below to help differentiate the pros and cons between matte and glossy screens.

 Matte(Anti-Glare) ScreenGlossy(Clear) Screen
Glare on ScreenLess glare if the more matte coatEasily affected by indoor lighting, sunlight, etc.
LifespanDisperses glare, no need to increase screen brightness to view content, so backlight and LCD lifespan will be longerNeed to maintain higher brightness to view content affected by glare. Increased backlight power will also reduce the life of the LCD.
Display QualityThe thicker the matte layer, the more it affects image quality (color, clarity)No coating, maintain accurate native color performance
CleanlinessCoating resists fingerprints and smudges, keeping the screen cleanMore prone to fingerprints and smudges

Side View

From the side view, the TV is in the ‘S’ shape to provide more beauty. The thinnest point is about 1cm, at the top of the TVs. Because this 55-inch WebOS TV is an LCD TV it must have the components that increase its width. For example, the backlight module takes some space and it needs extra space to take out the heat. Overall, the side is in the smooth ‘S’ shape and we have tried our best to put more components into the TVs while keeping it lightweight. It seems like most of the users do not care about the side view because they spend 99% of the time viewing the TV’s front side. The thickest part is in the middle of the TV because the mainboard(motherboard) is installed over there. Except for the LED light stripes that produce lots of heat, the mainboard will produce heat as well because it contains CPU and GPU(for smart TVs). We will review the back later to see how the cooling system deals with the heat.

Back View

The back of this 55-inch WebOS TV is plastic material as we want to decrease the weight and the degree of interference to wifi signals, compared to the metallic back. Do not worry, as a TV manufacturer if you prefer a metallic back and bezel. The back design is not usual because it contains some “reinforcement ribs”. These reinforcement ribs are added to keep the back more stable when the TV falls into the ground by any accident, by sacrificing some of the width spaces. On the other hand, the protection shell of the motherboard is designed to leave with some extra gap to help reduce the heat. Besides, nothing more extra components are placed at the back. The back is extra clean and lightweight, to make sure that it is easy to use the TVs by connecting cables to the ports.

Accessories View

As a TV producer, we need to make sure that the accessories coupled with the TVs are good enough. When the clients buy TVs from us, they will get the package, remote, power cord, user manual, TV machine, TV mount(stand), or extra cost of wall mount. Here is an example of what these accessories look like with the 55-inch WebOS TV.

A WebOS-style remote control is provided as default. The shape of this remote is on the oval side, with a semi-circular shape at the very top, so the overall layout of the remote will be compact, with buttons that are a small distance to the sides. The bottom of the remote control also looks oval, but in fact the bottom is flat, so the remote control is able to stand on the table without having to rely on any object, which is a very advanced design. In addition, the remote control provides some shortcut program entrances, and we can also customize the entrances of these programs according to the customer’s needs. It’s worth noting that the Webos TV supports the mouse function, which means that a mouse can appear on the TV screen to allow the user to quickly select the function he wants without having to look for it slowly with the cross keys. WebOS remote control also comes with a voice input function, which is a feature that is not available on the average Android AOSP system. One last feature of this remote is that the center of the cross keys has a scroll wheel that provides quick up and down swipes just like a mouse. This wheel can be pressed down, just like the “Enter” button, and it feels great, with just the right amount of damping.

Let’s focus on another component that doesn’t look very impressive – the TV stand. For this 55-inch WebOS TV, we used a matte textured black plastic stand that resists stains and gives an overall more premium look. To make sure that this relatively large 55-inch TV can stand safely, we used a kickstand with a span of 23 centimeters, which has a triangular design that supports this machine very well.
As a TV factory, we have different suppliers of stands, so customers don’t have to worry that we only use matte black plastic stands. On the contrary, we are able to match different stands according to your needs, such as metal stands, silver stands, mirror texture stands, and so on. Below is a picture of a matte black plastic tripod and a black mirror plastic tripod, so you can compare them carefully.

Triangle curved tripod design, not a pure triangle, curved triangle design more balanced aesthetics. The span is 22cm wide to ensure that the two stands can fully support the stability of the TV.

Display Performance

As a 55″ WebOS TV, or to use it as a monitor, we need it to be able to provide a good display,
Next, we will use a Datacolor SpyderX Elite colorimeter to test the display of this TV, our engineering room is equipped with more professional instruments, such as the CA-310. Since this article is our first test article, we will use a more convenient colorimeter to test, if you are interested in our 55-inch TV (Bulk) If you are interested in our 55-inch TV (buy in bulk) and want to know more details parameters, you are welcome to contact us at any time!

We will test these items: brightness, contrast, color uniformity, brightness uniformity, color gamut, color accuracy, and grayscale response. All these tests are performed in a dark room.

Brightness & Contrast

The MH-55WF01F uses DLED backlighting technology, DLED stands for Direct Entry, which means that the light beads and strips are mounted evenly on the back of the TV, which maximizes the maximum brightness to be displayed evenly on the screen. For larger TVs we will use DLED technology, for smaller sizes such as 32″ we will use ELED technology (Edge). Since we are a TV factory, we can even use ELED technology if you want to reduce costs.

After resetting the display settings in the TV’s menu, which defaults to 100% brightness, we used Spyder X Elite to read the brightness of this 55-inch TV. After resetting the display settings in the TV’s menu, which defaults to 100% brightness, we used the Spyder X Elite to read the brightness of this 55″ TV. It had a default setting of 278.1 cd/m² of maximum brightness. This brightness is pretty standard and is perfectly adequate for a TV set for indoor use. We also tested it in the dark in order to get its contrast ratio. At 100% brightness, a black picture was only 0.25 cd/m², which makes up a contrast ratio of 1090:1. Additionally, we tested it at 75% brightness, 50% brightness, 25% brightness, and 0% brightness respectively, and the data is in the table below.

Menu Brightness SettingsWhite luminance (cd/m²)Black luminance (cd/m²)Contrast Level (x:1)
100%278.10.251090:1
75%237.10.211120:1
50%192.80.181050:1
25%141.70.131120:1
0%92.20.091080:1

As a result, the average contrast level is 1092:1, about 1100:1. It is a little lower than 1200:1 as indicated by the panel default data. Please notice this data is measured by its default setting. There are several picture modes (basic, Standard, Vivid, Cinema, Sports, Game). We will test and show the data below.

SettingsWhite luminance (cd/m²)Black luminance (cd/m²)Contrast Level (x:1)
Basic261.60.201320:1
Standard280.50.181530:1
Vivid280.60.181530:1
Cinema248.90.201260:1
Sports281.10.191479:1
Game292.30.181590:1

The test data from these different modes shows that this 55-inch WebOS TV still has a lot of room for operational improvement in terms of brightness and contrast (if the customer is happy to use these modes), with Game mode, for example, approaching a brightness of 300 and bringing the contrast ratio in Sport mode to a staggering 1,590:1. Of course different people will have different preferences, and we’ll be making sure that these settings can satisfy most people.

Luminance Uniformity

It is the task of our engineers to make the light emanate evenly from the TV screen. Generally speaking, the number of backlight strips, the way they are distributed, the various optical films (diffusers, reflectors, etc.), and the uniformity of the LCD glass affect the Luminance Uniformity. we tested the following data to make sure that the luminance of this 55-inch TV would be very uniform, but unfortunately, the luminance of this TV in the showroom was not uniform enough and was concentrated in the four corners.

QuadrantLuminance (cd/m²)Difference To MAX
1164.926%
2208.96%
3177.720%

5(MAX)221.50%
6213.04%
7179.419%
8211.35%
9175.221%

All four corners are much less bright than the center, probably because of the diffusion panel.

Color Gamut

This 55-inch TV utilizes white LEDs as backlights, so its color gamut depends a lot on the parameters of these backlights. If it’s a QLED TV with a quantum coating, or quantum film, then its color gamut will be very good. As a TV manufacturer, we also progress, so we have also produced QLED TVs and sold a very large number of them last year in 2023. In the long run, QLED TVs are going to be one of the products that we’re going to use to enter the high-end market. The graph below shows the results of our color gamut test with the SpyderX Elite, which would have been more accurate if we had used the CA-310 color analyzer in the engineering room.

The color gamut of this TV is very standard, reaching 72% of the NTSC color gamut and 77% of the DCI-P3 color gamut, which is a must-have color gamut value for modern TVs. Some wide-gamut QLED TVs, or OLED TVs, are capable of reaching close to 100% DCI-P3 color gamut. We’ll be testing a QLED 75-inch TV in our showroom next.
