LCD TV has a slim appearance, lightweight body, power saving and environmental protection. Since 2004, it has been popularized in the domestic market, and after years of continuous development and technological progress, it is still rejuvenated today. Although OLED technology TVs have ambitions to replace them in recent years, factors such as high market prices and shorter service life than LCD TVs have been plaguing the market popularity of OLED technology TVs.
On the other hand, the TFT-LCD panel used by LCD TVs is still evolving in technology, and recently we learned from TCL Huaxing that the HVA technology developed by Huaxing Optoelectronics is constantly improving the existing TFT-LCD panel products, from a market point of view, it makes the market popularity of OLED panels greatly delayed again, and the large-screen TFT-LCD panels under the blessing of HVA technology have achieved a leap in energy consumption, contrast, response speed, refresh rate and curvature angle of view. HVA technology can even be used on Mini LED TVs, knowing that Mini LEDs are a strong competitor to OLED.
Comparison of traditional VA soft screen and IPS hard screen technology
In terms of traditional TFT-LCD panels, the LCD VA soft screen technology is much better than the early LCD TN screen technology, but compared with the IPS hard screen launched by the Korean manufacturer LG, the early VA soft screen still has a slight gap in terms of various parameters and display effect comparison.
Specifically, the IPS viewing angle is better than that of ordinary VA screens, and users can see more clearly when standing on the side of the screen. In terms of color, the panel of IPS technology is better than the VA soft screen in terms of color gamut and color accuracy, and the contrast is higher in terms of contrast, the tolerance and contrast of the VA screen are higher, the black and white in the picture are more pure, and the VA screen is stronger than the IPS. The order of liquid crystal molecules of the IPS screen is horizontal, and its liquid crystal molecules can withstand the slight pressure of our hands, bringing a harder touch, so the IPS screen is also called a hard screen. The LIQUID crystal molecules of the VA screen present a vertical arrangement order, when encountering ordinary slight external force touch, there will be a crow's feet pattern, so it is also called a soft screen, of course, on the terminal large-size LCD TV, the TV using the VA screen will generally add a layer of high transmittance plate on the outside of the screen, which can play a better protective role.
After such a comparison, the ordinary VA soft screen seems to be inferior to the IPS hard screen in terms of overall technology, but things are constantly evolving, and the same is true for technological progress.
HVA technology debuted and laid a number of strengths to catch up
Since the advent of VA technology, technological innovation for it has been continuous, and MVA and PVA representative technologies have emerged, competing with IPS technology and even performing better in the high-end market. Unfortunately, MVA and PVA technology cost are higher, MVA is developed by the Japanese, representative of the product is Sharp screen. PVA technology is from South Korea's Samsung, MVA and PVA technology is not mastered by Chinese companies.
If domestic panel manufacturers want to complete the breakthrough of high-end TFT-LCD panel technology in the non-OLED large-screen panel market and achieve independent control, they must bypass and avoid MVA and PVA. As a result, a technology called HVA was born at TCL Huaxing. The emergence of HVA technology is an innovation in the existing VA soft screen technology.
Compared with the traditional Japanese MVA technology, HVA technology does not produce light leakage caused by excess protruding parts of the panel surface, it simplifies the manufacturing process, reduces costs at the same time, improves the opening rate, can display higher brightness, and presents a more three-dimensional and sharper picture quality; The penetration rate of HVA technology can be increased by about 15% to 20%; Under the same picture quality, the higher the penetration rate of the product, the lower the brightness of the required backlight, and the corresponding consumption of less power. HVA technology not only improves the penetration rate of products, but also makes the product energy consumption lower, energy saving and more environmental protection.
In terms of contrast, VA technology has done a good job, HVA technology has gone further, especially for the dark state light leakage has been greatly improved, making the dark state darker, so that the corresponding products have an absolute advantage in contrast, the intuitive feeling of high contrast is that black looks more pure, and the picture layering is stronger; Compared to IPS technology, HVA technology can have a contrast ratio of 3 times or more, TCL
Wang Zui, director of Huaxing MNT development platform, said that the contrast ratio of mass-produced products has reached 4000:1, and in the field of ultra-high-end products, it can even reach 8000:1.
In addition, products using HVA technology can achieve OD1ms, which is the highest level in the industry today. In use, whether it is dealing with speed games, first-person shooters, or intense screen scenes, you can achieve high-speed screen switching without smearing.
Not only that, under the design, process, material and drive of HVA technology, the liquid crystal is faster when it is rotated to achieve picture transformation; The better circuit design drives more efficiently, thus achieving a high refresh rate specification of up to 360Hz or even 480Hz, which is also an indispensable key to watching TV and playing games, and a high refresh rate means that the picture is smoother.
In the B-end market, HVA technology can also enable high-end curved products to achieve greater viewing angles, providing users with a wider field of view and a stronger immersive experience.
Wang Drunk introduced, TCL ultra-high-definition 4K TV, quantum dot high-end TV and curved TV have used HVA technology, HVA technology has now covered most of the Huaxing panel production line, and even the next generation of COMPETITION with OLED technology Mini LED also benefited, under the cost reduction and efficiency increase, the use of HVA technology Mini LED panel is expected to win the battle with OLED panel, "on who is the future display technology" line battle.
The various benefits of HVA technology have been infinitely expanded in high-end scenarios. Gao Xiang, director of TCL Huaxing MNT Product Planning Department, revealed that TCL's high-end e-sports display products and curved screen products have been welcomed by hardcore players and people in the financial industry. In addition, in the split-screen scene, high-end medical and other special use scenarios, TCL terminal products using HVA technology have been warmly welcomed by the market.
