lcd display refresh rate made in china

Created by the Chinese manufacturer BOE, the fastest gaming monitor in the world has been announced via social networks and comes with a refresh rate of 500Hz, enough even for the most demanding competitive gamers.

Available to buyers in China, the monitor for gaming enthusiasts who put speed first comes with a 27-inch diagonal and only Full HD resolution. While the clarity of the image certainly suffers, the framerate has at least a chance to get close to the stunning values ​​needed to highlight the capabilities of this monitor, at least in some games.

By comparison, the fastest gaming laptops delivered by manufacturers such as Asus, Acer and Alienware cap the image refresh rate at 360Hz, which is generally considered sufficient for most situations.

Although it looks good in the spec list, the refresh rate is not exactly the absolute measure of performance, outlined by some monitor manufacturers. The equations include other factors such as the response time of the LCD technology used, the ability of the PC used to reach that frame rate, and the user’s ability to notice the difference, for example, between a monitor with a refresh rate of 144Hz and a monitor. 240Hz, or more. In general, the perceived benefits on the image clarity side are more easily noticeable between the 60Hz and 120Hz thresholds, with the actual speed of the LCD panel (response time, measured in milliseconds) becoming more important after this threshold. For example, an LCD monitor with TN technology and 120Hz refresh rate will be noticeably better than a hypothetical LCD monitor with IPS technology and refresh rate at 240Hz, simply because the ghosting effect is less noticeable on the TN monitor.

In this case, it seems that we are dealing with a new generation LCD technology, called high-mobility oxide backplane, which allows the use of ultra-high reresh rates without the benefits being canceled by the screen with time. insufficient response.

Unfortunately, the announced product still exists at most at the prototype stage, it remains to be seen how long it will take until the new type of screen will be commercially available. In addition, being a niche product for a select category of users, the new ultra-fast LCD screen is unlikely to deliver the viewing angles and contrast levels appreciated by conventional IPS solutions. Another potential obstacle to an absolutely ideal gaming experience is hardware requirements, with only a few models of NVIDIA and AMD graphics accelerators being able to reach the threshold of 500 frames per second in games, the cost of such a PC quickly reaching dizzying.

Zhongguancun online news: On February 23, according to the official public account of Visionox. Visionox officially released the first 1Hz low-power AMOLED display in China, which can achieve a wide range of dynamic refresh rates from 1 to 120Hz, equipped with the screen by Visionox (Hefei) G6 full-flexible AMOLED production line for mass production.

According to Visionox, the AMOLED display can achieve a wide range of dynamic refresh rates from 1-120Hz through Hybrid-TFT technology. It is understood that Hybrid-TFT technology can greatly reduce the power consumption of the mobile phone screen power consumption, when the mobile phone is in the screen-off display, reading and other low refresh rate application scenarios, automatically reduce the screen refresh rate to 1Hz, thereby reducing power consumption. In addition, the screen features Visionox"s "Top Pixel Arrangement", which has the world"s highest visually equivalent pixel density, making the display more uniform, sharper and more detailed.

The Realme Q3t runs on Realme UI 2.0 based on Android 11. This device features a 6.67-inch FHD+ IPS LCD panel with a resolution of 1080×2412 pixels. The display is capable of a 144Hz refresh rate and 600 nits of peak brightness. That said, the Realme Q3t has an impressive 90.8 percent screen-to-body ratio, indicative of razor-thin bezels on the front, although the bottom bezel is rather prominent. The Realme Q3t also has a side-mounted fingerprint sensor.

Realme’s approach to the display differs from its competitors that offer AMOLED displays with the standard 60Hz refresh rate but support HDR content playback or a DCI-P3 color gamut in some cases.

The Realme Q3t has a hole-punch cutout for the camera on the upper left corner of the display. The front-facing camera is a 16MP unit. On the rear, the three-camera array comprises a 48MP primary camera flanked by what is reported to be a 2MP macro lens and a 2MP depth sensor.

The screen in question is actually a laptop display, a 16-inch LCD that the Chinese site IT Home(opens in new tab) brought to our attention (via Tom’s Hardware(opens in new tab)).

The panel was shown off at the World Conference on Display Industry in China, but besides the size and refresh rate, no other specs were provided for the screen, although it was demonstrated at the event.

BOE showed off the display in a laptop with an AMD Ryzen CPU and Nvidia GPU – presumably, or at least those logos were on the chassis of the notebook, so it’d be very odd if the stickered components weren’t inside the portable.

The 600Hz screen seems like it’s still in the earlier stages of development, mind you, because while functioning, the display was attached to the laptop base using tape, apparently.

Does the world really need a 600Hz panel? Is there any point to this seemingly relentless drive to up refresh rates to increasingly colossal levels? At the beginning of the year, BOE was trumpeting a 500Hz gaming monitor, and already before the year is out, a 600Hz screen has trumped that effort, and by a considerable distance.

Isn’t this all getting very silly? Well, we think that’s true in the main, but that said, there is a target audience for this kind of ultra-high refresh rate panel, though it’s arguable exactly what such a display brings to the table.

That target audience would be professional gamers, playing the likes of Counter-Strike: Global Offensive, where it’s possible to drive really, really high frame rates (as they aren’t demanding titles).

It’s worth noting that we can presume the 600Hz screen is 1080p resolution, given that the need to push high frame rates means it won’t be higher-res. In that case, 600 fps would never be attainable – and remember, this is a laptop too, making hitting those heights a trickier task in terms of available GPU grunt. This is another point – we’re not sure why this has been created as a laptop panel, rather than a standalone monitor like BOE’s aforementioned 500Hz effort.

As Tom’s Hardware rightly points out, one advantage of cranking the refresh rate of panels this high is that you get a better frame time – a smoother and more consistent delivery of frames – but there are very much diminishing returns on this front as you go up to dizzying refresh rates. 360Hz for example offers a frame time of 2.7ms, whereas 600Hz drops that to 1.66ms. Now, a basic 60Hz panel is 16.66ms, which is fine for casual gaming, so the drop in going from here to 360Hz and 2.7ms is a sizeable one (at least to competitive gamers). But further decreasing that to 1.66ms is pretty marginal, to say the least.

Is a person really likely to appreciate that tiny difference? Can the human eye even detect the benefits of 600Hz (or even 500Hz, or lower) panels? In truth, the answer for the vast, vast majority of folks, is probably not. But for a vanishingly small niche of the top pro gamers, they might benefit from an ultra-high refresh rate panel in terms of a smidgeon of a smoother gameplay experience that may be perceptible only in terms of a very slight difference in the feel of the game. But then, even the thinnest wisp of a potential advantage is something high-earning gaming pros could well find value in chasing.

For the rest of us non-gamer-god types, though, these screens built to reach towering refresh rates are pretty pointless. And the extreme heights to which all this has been pushed over the course of 2022 will inevitably seem silly to us mere mortals of the gaming world. Realistically, we’ll be absolutely fine and dandy with 144Hz, or 240Hz if you want to push the boat out.

Supposedly there are 480Hz monitors coming for 2023 inbound from AU Optronics and LG Display, too, so whatever your feelings about superfast refresh rates, presumably we’ll see some of these models pitching up at some point next year.Today"s best Gaming Monitor deals

One of such trade-offs that buyers often have to bear is choosing between a higher refresh rate or an AMOLED panel. But which is more important for a better experience: a fast 120Hz LCD panel or a 60Hz AMOLED one? Let"s find out.

How fast a screen can refresh affects how well it can simulate motion. In other words, it makes animations appear more natural and fluid as opposed to laggy and jittery. Earlier, the standard refresh rate for smartphones used to be 60Hz. But ever since OnePlus popularized high refresh rate displays, they have become common in the tech industry.

​​​​Today, even some budget models come with a 120Hz refresh rate, mostly Chinese phones. You can notice the difference between a 60Hz and a 90Hz/120Hz panel when gaming and scrolling through apps or social media.

But before you get too excited, note that the jump in performance, i.e., how smooth the animations feel, doesn"t keep increasing consistently. A jump from 60Hz to 90Hz is a 50% upgrade, whereas a jump from 90Hz to 120Hz is only a 33.33% upgrade. And a jump from 120Hz to 144Hz is a negligible 20% upgrade. That means that you"re going to get to the point of diminishing returns beyond 120Hz, which is the sweet spot for smartphone refresh rates.

Unlike a regular LCD, an AMOLED display provides more vivid image quality, consumes less power, and does a better job at reducing screen glare. This means that any content you consume on your phone—from games to movies to social media—will appear brighter and more colorful, all while saving your battery life.

Each pixel produces its own light on an AMOLED panel, unlike LCD or IPS panels that use a backlight to illuminate the screen. Because of this, the former can show darker colors and deep blacks more accurately since it can just turn a pixel off to represent an absence of light. On the latter, the same colors appear washed out or faded.

When using Dark Mode (or Night Mode) on an AMOLED panel, the workload of the display is reduced since a measurable portion of the screen is basically turned off. Only the pixels that show colors need to be illuminated, whereas the black pixels can remain shut off. As a result, you save battery life while viewing dark content on an AMOLED screen.

If you"re a gamer, a high refresh rate display will serve you better than an AMOLED one, making your gaming experience much smoother. However, note that the higher the refresh rate, the faster you will drain your battery. Also, keep in mind that many mobile games only support 60Hz, so the benefit of having a 90Hz or 120Hz screen may be redundant.

As premium features become more common, they"re quickly making their way into budget phones. Having a high refresh rate AMOLED display is obviously better if you can find such a device in the budget category. But if you can"t, you have to trade one for the other.

Since budget phones come with weaker chips, the games you play may not always take advantage of that high refresh rate screen, making them a bit unnecessary apart from smoother scrolling of social media feeds. However, an AMOLED panel will continue to enrich your viewing experience no matter what.

Recently, a few LCD displays with 240 Hz frame rate have appeared on the market. I evaluated a LCD display with 240 Hz frame rate in terms of its temporal characteristics, progression between frames, and chromatic characteristics. The display showed (a) accurate frame durations at millisecond level, (b) gradual transition between adjacent frames, and (c) acceptable chromatic characteristics.

LCD technology is constantly improving in ways that are beneficial to the needs of visual scientists. It used to be that LCD displays were not suitable for displaying objects in high-speed motion because of relatively slow updating speeds of LCD pixels. Recently, a few LCD displays with 240 Hz frame rate have appeared on the market, designed for computer game players. Here, I evaluate a LCD display (ROG PG258Q, ASUS) with 240 Hz frame rate in terms of its temporal characteristics, progression between frames, and chromatic characteristics. The display showed accurate frame durations at millisecond level and a gradual transition between adjacent frames, with no evidence of ghosting from one frame to the next. The full response spectra for the three color channels are also presented.

Stimuli were controlled by web pages using HTML, JavaScript, and WebGL technology on a PC (Intel Core i7-6700 CPU, NVidia GeForce GTX 1060 GPU). The LCD display was connected to the graphics card through a DisplayPort cable of a PC running 64-bit Microsoft Windows 10 Home Edition (Chinese version). The web browser was Firefox (version number 53.0, 64-bit). OpenGL shader programs were used to make sure the stimuli were generated in real-time on the GPU and to make sure the stimuli were displayed reliably at the 240 Hz frame rate. The driver of the LCD display was set to a 1920 × 1080 resolution, 240 Hz frame rate, 32-bit color mode, and G-Sync was turned on (G-Sync is a sync technology developed by Nvidia aimed to eliminate screen tearing, and more details are available on the Nvidia web site).

Temporal characteristics were measured by a light meter (LM03, Cambridge Research Systems Ltd., which is a demonstration product, provided freely at Asia Pacific Conference on Vision 2014, but not available for sale by CRS Ltd.) and a high-speed video camera (RX100-V, SONY). The LM03 light meter was designed for high temporal resolution but not necessarily accurate measurement of intensity. Precise measurement of output intensities to measure the gamma properties, for instance, is not the aim of this review. Temporal intensity variations of red, green, and blue channels and frame switching were measured as described later.

A sequence of frames was presented, with red, green, and blue separately increasing (in 240 steps) from 0 to 1 and then decreasing again, with a black frame (r = 0, g = 0, b = 0) inserted between two continuous frames in order to separate continuous change clearly. The sample interval of the light meter was set as 500 microseconds and the monitor frame rate was set to 240 Hz. A subset of the data from the green channel measurements can be seen in Figure 1, which shows (a) the temporal intensity variation between the minimum value and the peak value was regular, sharp, and rapid; (b) transitions from dark-to-light were slower than transitions from light-to-dark; and (c) distance between adjacent peaks were in the range 8 to 8.5 ms which was consistent with frame duration 8.3 ms (two frames in 240 Hz frame rate). The variability may derive from aliasing between the sampling frequency (500 Hz) and the display frequency (240 Hz) rather than any actual imprecision in the frame rate.

Animated numbers were displayed on a constant changing background. The number increased one at each frame. The frame rate was set as 240 Hz. The frame sequence was recorded by the high-speed video camera with a sample rate 1000 Hz.

Figure 2 shows nine continuous frames captured by the camera, representing three display frames on the monitor (labeled 680, 681, and 682). Display Frame 681 corresponded to camera Frames 2, 3, 4, and 5 and display Frame 682 corresponded to camera Frames 6, 7, 8, and 9. Camera Frames 2, 3, 4, 6, 7, and 8 showed the gradual changes between two display frames as the LCD pixels switched.

Continuous frames captured by the camera (sampling at 1 kHz) with the monitor updating at 240 Hz. Each displayed frame showed the frame number (680–682 here). Camera frames (numbered 1–9 here) showed the smooth transition from one display frame to the next, taking four frames to change, as expected. In camera Frames 1, 5, and 9, you can see that the frame has completely switched, with no evidence of ghosting from the previous frame.

Frame switching between hexagons and checkerboard. From left to right and from top to down, there were six continuous camera frames (1–6). Frame 1 corresponded with a hexagon display frame and frames from 2 to 6 show the transition to a checkerboard display frame. There was fusion between the hexagons and the squares in frames from 2 to 5.

The stimulus frames were full screen uniform background which r, g, b values varied from 0 to 1 in 16 steps separately. A spectrometer (eye-one pro, X-rite) measured spectrum of the display from 390 nm to 740 nm with 5 nm step, as shown in Figure 4. Further testing is needed to determine the monitor’s chromatic characteristics precisely.

Spectrum of red, green, and blue channels. The r, g, and b values were varied from 0 to 1 in 16 steps separately and are shown as increasing lines in their corresponding color.

This 240 Hz LCD display has the following characteristics: (a) accurate frame durations at millisecond level; (b) gradual transition between adjacent frames; and (c) acceptable chromatic characteristics.

The Chinese display maker BOE has showcased a new display panel which sets a new benchmark in the world of gaming monitors. BOE"s new monitor offers a refresh rate of up to 500Hz, surpassing the current best monitors that can reach up to 360Hz.

The 27-inch monitor uses a high-mobility oxide TFT technology and offers full HD 1080p resolution (via Videocardz). The lower resolution is understandable considering the insanely high 500Hz refresh rate of the display. Even current 360Hz monitors are limited to 1080p resolution. The panel uses an 8-lane DisplayPort connection and offers a 1ms response time and 8-bit color gamut support.

BOE is one of the leading manufacturers of LCD, LED and OLED panels. The company is a market leader in the oxide semiconductor display market. It also makes foldable displays, which have been featured on smartphones like the Motorola Razr and Huawei Mate X.

"With years of technology accumulation, BOE has made important breakthroughs in the field of oxide semiconductor display technology, overcoming industry problems such as copper (Cu) easy to diffuse, easy to oxidize, and easy to drill and engrave, and is the first in the industry to achieve mass production of copper interconnect stack structures. And the integration of high refresh rate, high resolution, low power consumption oxide display technology," reports Chinese publication Sina.com (machine-translated by Google).

Note that this monitor is a prototype unit, meant for demonstration only. We don’t know when, if ever, BOE plans to commercially launch a monitor with a 500Hz refresh rate. BOE also didn’t detail whether there are any tangible benefits of having a display that offers a whopping 500Hz refresh rate. In any case, you"ll definitely need one of the best graphics cards out there to drive this thing.

Recently, we often have customers ask us about the refresh rate of led screen, most of them are for filming needs, such as XR virtual photography, etc. I would like to take this opportunity to talk about this issue To answer the question of what is the difference between a high refresh rate and a low refresh rate.

Refresh rate and frame rate are very similar. They both stands for the numbers of times a static image is displayed per second. But the difference is that the refresh rate stands for the video signal or display while the frame rate stands for the content itself.

The refresh rate of a LED screen is the number of times in a second that the LED screen hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate for LED screens includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.

The frame rate of video is usually 24, 25 or 30 frames per second, and as long as it is higher than 24 frames per second, it is generally considered smooth by the human eye. With recent technological advances, people can now watch video at 120 fps in movie theaters, on computers, and even on cell phones, so people are now using higher frame rates to shoot video.

Refresh rate can be divided into vertical refresh rate and horizontal refresh rate. The screen refresh rate generally refers to the vertical refresh rate, that is, the number of times the electronic beam repeatedly scanned the image on the LED screen.

In conventional terms, it is the number of times that the LED display screen redraws the image per second. The screen refresh rate is measured in Hertz, usually abbreviated as “Hz”. For example, a screen refresh rate of 1920Hz means that the image is refreshed 1920 times in one second.

What you see on the LED video wall is actually multiple different pictures at rest, and the motion you see is because the LED display is constantly refreshed, giving you the illusion of natural motion.

Because the human eye has a visual dwelling effect, the next picture follows the previous one immediately before the impression in the brain fades, and because these pictures are only slightly different, the static images connect to form a smooth, natural motion as long as the screen refreshes quickly enough.

A higher screen refresh rate is a guarantee of high-quality images and smooth video playback, helping you to better communicate your brand and product messages to your target users and impress them.

Conversely, if the display refresh rate is low, the image transmission of the LED display will become unnatural. There will also be flickering “black scan lines”, torn and trailing images, and “mosaics” or “ghosting” displayed in different colors. Its impact in addition to video, photography, but also because tens of thousands of light bulbs flashing images at the same time, the human eye may produce discomfort when viewing, and even cause eye damage.

A higher led screen refresh rate tells you the ability of a screen’s hardware to reproduce the screen’s content several times per second. It allows the motion of images to be smoother and cleaner in a video, especially in dark scenes when showing fast movements. Other than that, a screen with a higher refresh rate will be more suitable for the content with a more significant number of frames per second.

Typically, a refresh rate of 1920Hz is good enough for most LED displays. And if the LED display needs to display high speed action video, or if the LED display will be filmed by a camera, the LED display needs to have a refresh rate of more than 2550Hz.

The refresh frequency is derived from the different choices of driver chips. When using a common driver chip, the refresh rate for full color is 960Hz, and the refresh rate for single and dual color is 480Hz. when using a dual latching driver chip, the refresh rate is above 1920Hz. When using the HD high level PWM driver chip, the refresh rate is up to 3840Hz or more.

HD high-grade PWM driver chip, ≥ 3840Hz led refresh rate, screen display stable and smooth, no ripple, no lag, no sense of visual flicker, not only can enjoy the quality led screen, and effective protection of vision.

In professional use, it is critical to provide a very high refresh rate. This is especially important for scenes geared towards entertainment, media, sporting events, virtual photography, etc. that need to be captured and will certainly be recorded on video by professional cameras. A refresh rate that is synchronized with the camera recording frequency will make the image look perfect and prevent blinking. Our cameras record video usually at 24, 25,30 or 60fps and we need to keep it in sync with the screen refresh rate as a multiple. If we synchronize the moment of camera recording with the moment of image change, we can avoid the black line of screen change.

LED display refresh rate of not less than 3840Hz, the camera to capture the picture screen stability, can effectively solve the image of the rapid motion process of trailing and blurring, enhance the clarity and contrast of the image, so that the video screen delicate and smooth, long time viewing is not easy to fatigue; with anti-gamma correction technology and point-by-point brightness correction technology, so that the dynamic picture display more realistic and natural, uniform and consistent.

Therefore, with the continuous development, I believe the standard refresh rate of led screen will transition to 3840Hz or more, and then become the industry standard and specification.

One thing we should be aware of is that, unlike grayscale, there is a certain risk of too high a refresh rate. When the refresh rate gets higher, it demands more and more quality of LEDs. If the quality of the LED is not good, it will not be able to withstand the impact of high refresh rates and will be easily damaged. Normally, we should set the refresh rate below the maximum value set at the factory, such as 3840Hz, if the refresh rate is too high, it will affect the life of the LED.

Whether you want to use an indoor or outdoor advertising LED screen for branding, video presentations, broadcasting, or virtual filming, you should always choose an LED display screen that offers a high screen refresh rate and synchronizes with the frame rate recorded by your camera if you want to get high-quality images from the screen, because then the painting will look clear and perfect.

The best — and easiest — way to know what refresh rates your system can support is by playing games and seeing how they perform. Use a frame rate monitoring utility like Fraps to display your current FPS (frames per second) as you play. Most frame rate monitoring utilities will have the ability to benchmark your average FPS , which keeps track of how your system performs over the course of a gameplay session.

Ideally, you’ll want the game’s frame rate to match the monitor’s refresh rate 1:1 for an ideal experience. For example, your system should be outputting 144 FPS to get the full benefit of a 144Hz monitor.

That said, you can still enjoy a higher refresh rate, even if it doesn’t reach the limits of what your display is capable of. Playing at 110Hz is better than playing at 60Hz, and you can always upgrade your CPU and GPU later to get to 144 FPS.

If your system struggles to run games higher than 60 FPS, it’s unlikely you’ll see much benefit from a high-refresh rate display, but it might be worth investing in one if your PC is capable of producing higher than 60 FPS.
